Currently we do not have full support for broadcast from

The code in wmi_call uses the wil->wmi_call completion
structure to wait for a reply.
In some scenarios, complete was called twice on the
completion structure. This happened mainly with a disconnect
event which can arrive both unsolicited and as a reply to
a disconnect request. In this case the completion structure
was left marked as "done" and the next wmi_call returned
immediately with a corrupted reply buffer. This caused
unexpected results including crashes.
Fix this by adding the missing call to reinit_completion.

By default, AP SME is handled by driver/FW.
In case disable_ap_sme is true, driver doesn't turn-on
WIPHY_FLAG_HAVE_AP_SME and the responsibility for
AP SME is passed to user space.
With AP SME disabled, driver reports assoc request frame
to user space which is then responsible for sending assoc
response frame and for sending NL80211_CMD_NEW_STATION.
Driver also reports disassoc frame to user space
which should then send NL80211_CMD_DEL_STATION.
NL80211_CMD_SET_STATION with NL80211_STA_FLAG_AUTHORIZED

Not clearing the previous tx bit rate status
results in a ambigous tx bit rate reporting to
mac80211/cfg80211, for example the previous bit
rate status would have been marked as legacy rate
, while the current rate would have been an HT/VHT
rate with the tx bit rate flags set and this results
in exporting tx bitrate as legacy rate but with HT/VHT
rate flags set, fix this by clearing the tx bitrate

Station pointers are RCU protected so driver must
be extra careful if it tries to store them
internally for later use outside of the RCU
section it obtained it in.
It was possible for station teardown to race with
some htt events. The possible outcome could be a
use-after-free and a crash.
Only peer-flow-control capable firmware was
affected (so hardware-wise qca99x0 and qca4019).
This could be done in sta_state() itself via
explicit synchronize_net() call but there's
already a convenient sta_pre_rcu_remove() op that
can be hooked up to avoid extra rcu stall.
The peer->sta pointer itself can't be set to
NULL/ERR_PTR because it is later used in
sta_state() for extra sanity checks.

In countries where basic operation of channel 169 is allowed,
this fixes the below WARN_ON_ONCE in Rx and fixes the station
connectivity failure in channel 169 as the packet is dropped
in the driver as the current check limits to channel 165. As of
now all the packets beyond channel 165 is dropped, fix this
by extending the range to channel 169.

Currently, the common ath9k_common module needs to have a
dependency on RELAY and DEBUG_FS in order to built. This
is usually not a problem. But for RAM and FLASH starved
AR71XX devices, every little bit counts.
This patch adds a new symbol CONFIG_ATH9K_COMMON_DEBUG
which makes it possible to drop the RELAY and DEBUG_FS
dependency there and move it to ATH_(HTC)_DEBUGFS.
Note: The shared FFT/spectral code (which is the only user
of the relayfs in ath9k*) needs DEBUG_FS to export the relayfs
interface to dump the data to userspace. So it makes no sense
to have the functions compiled in, if DEBUG_FS is not there.

The 10.4 firmware adds extended peer information to the
firmware's statistics payload. This additional info is
stored as a separate data field and the elements are
stored in their own "peers_extd" list.
These elements can pile up in the same way as the peer
information elements. This is because the
ath10k_wmi_10_4_op_pull_fw_stats() function tries to
pull the same amount (num_peer_stats) for every statistic
data unit.

For several reasons, it is desirable to use {READ,WRITE}_ONCE() in
preference to ACCESS_ONCE(), and new code is expected to use one of the
former. So far, there's been no reason to change most existing uses of
ACCESS_ONCE(), as these aren't currently harmful.
However, for some new features (e.g. KTSAN / Kernel Thread Sanitizer),
it is necessary to instrument reads and writes separately, which is not
possible with ACCESS_ONCE(). This distinction is critical to correct
operation.
It's possible to transform the bulk of kernel code using the Coccinelle
script below. However, for some files (including the ath9k ar9003 mac
driver), this mangles the formatting. As a preparatory step, this patch
converts the driver to use {READ,WRITE}_ONCE() without said mangling.

The txpower is being recalculated when adding interface to make sure
txpower won't overshoot the spec, and when removing the interface,
the txpower should again to be recalculated to restore the correct value
from the active interface list.
Following is one of the scenario
vdev0 is created as STA and connected: txpower:23
vdev1 is created as P2P_DEVICE for control interface: txpower:0
vdev2 is created as p2p go/gc interface: txpower is 21
So the vdev2@txpower:21 will be set to firmware when vdev2 is created.
When we tear down the vdev2, the txpower needs to be recalculated to
re-set it to vdev0@txpower:23 as vdev0/vdev1 are the active interface.

Whenever firmware crashes, and both CONFIG_ATH10K_DEBUGFS and
CONFIG_ALLOW_DEV_COREDUMP are enabled, dump information about the crash via a
devcoredump device. Dump can be read from userspace for further analysis from:
/sys/class/devcoredump/devcd*/data
As until now we have provided the firmware crash dump file via fw_crash_dump
debugfs keep it still available but deprecate and a warning print that the user
should switch to using dev_coredump.
Future improvement would be not to depend on CONFIG_ATH10K_DEBUGFS, as there
might be systems which want to get the firmware crash dump but not enable
debugfs. How to handle memory consumption is also something which needs to be
taken into account.

Ath10k reports the phy capability that supports P2P_DEVICE interface.
When we use the P2P supported wpa_supplicant to start connection, it'll
create two interfaces, one is wlan0 (vdev_id=0) and one is P2P_DEVICE
p2p-dev-wlan0 which is for p2p control channel (vdev_id=1).
ath10k_pci mac vdev create 0 (add interface) type 2 subtype 0
ath10k_add_interface: vdev_id: 0, txpower: 0, bss_power: 0
...
ath10k_pci mac vdev create 1 (add interface) type 2 subtype 1
ath10k_add_interface: vdev_id: 1, txpower: 0, bss_power: 0
And the txpower in per vif bss_conf will only be set to valid tx power when
the interface is assigned with channel_ctx.
But this P2P_DEVICE interface will never be used for any connection, so
that the uninitialized bss_conf.txpower=0 is assinged to the
arvif->txpower when interface created.
Since the txpower configuration is firmware per physical interface.
So the smallest txpower of all vifs will be the one limit the tx power
of the physical device, that causing the low txpower issue on other
active interfaces.
wlan0: Limiting TX power to 21 (24 - 3) dBm
ath10k_pci mac vdev_id 0 txpower 21
ath10k_mac_txpower_recalc: vdev_id: 1, txpower: 0
ath10k_mac_txpower_recalc: vdev_id: 0, txpower: 21
ath10k_pci mac txpower 0
This issue only happens when we use the wpa_supplicant that supports
P2P or if we use the iw tool to create the control P2P_DEVICE interface.

This reworks the ath9k driver to schedule transmissions to connected
stations in a way that enforces airtime fairness between them. It
accomplishes this by measuring the time spent transmitting to or
receiving from a station at TX and RX completion, and accounting this to
a per-station, per-QoS level airtime deficit. Then, an FQ-CoDel based
deficit scheduler is employed at packet dequeue time, to control which
station gets the next transmission opportunity.
Airtime fairness can significantly improve the efficiency of the network
when station rates vary. The following throughput values are from a
simple three-station test scenario, where two stations operate at the
highest HT20 rate, and one station at the lowest, and the scheduler is
employed at the access point:
Before / After
Fast station 1: 19.17 / 25.09 Mbps
Fast station 2: 19.83 / 25.21 Mbps
Slow station: 2.58 / 1.77 Mbps
Total: 41.58 / 52.07 Mbps
The benefit of airtime fairness goes up the more stations are present.
In a 30-station test with one station artificially limited to 1 Mbps,
we have seen aggregate throughput go from 2.14 to 17.76 Mbps.

The ar9300_eeprom logic is already using only 8-bit (endian neutral),
__le16 and __le32 fields to state explicitly how the values should be
interpreted.
All other EEPROM implementations (4k, 9287 and def) were using u16 and
u32 fields with additional logic to swap the values (read from the
original EEPROM) so they match the current CPUs endianness.
The EEPROM format defaults to "all values are Little Endian", indicated
by the absence of the AR5416_EEPMISC_BIG_ENDIAN in the u8 EEPMISC
register. If we detect that the EEPROM indicates Big Endian mode
(AR5416_EEPMISC_BIG_ENDIAN is set in the EEPMISC register) then we'll
swap the values to convert them into Little Endian. This is done by
activating the EEPMISC based logic in ath9k_hw_nvram_swap_data even if
AH_NO_EEP_SWAP is set (this makes ath9k behave like the FreeBSD driver,
which also does not have a flag to enable swapping based on the
AR5416_EEPMISC_BIG_ENDIAN bit). Before this logic was only used to
enable swapping when "current CPU endianness != EEPROM endianness".
After changing all relevant fields to __le16 and __le32 sparse was used
to check that all code which reads any of these fields uses
le{16,32}_to_cpu.

There are two ways of swapping the EEPROM data in the ath9k driver:
1) swab16 based on the first two EEPROM "magic" bytes (same for all
EEPROM formats)
2) field and EEPROM format specific swab16/swab32 (different for
eeprom_def, eeprom_4k and eeprom_9287)
The result of the first check was used to also enable the second swap.
This behavior seems incorrect, since the data may only be byte-swapped
(afterwards the data could be in the correct endianness).
Thus we introduce a separate check based on the "eepmisc" register
(which is part of the EEPROM data). When bit 0 is set, then the EEPROM
format specific values are in "big endian". This is also done by the
FreeBSD kernel, see [0] for example.
This allows us to parse EEPROMs with the "correct" magic bytes but
swapped EEPROM format specific values. These EEPROMs (mostly found in
lantiq and broadcom based big endian MIPS based devices) only worked
due to platform specific "hacks" which swapped the EEPROM so the
magic was inverted, which also enabled the format specific swapping.
With this patch the old behavior is still supported, but neither
recommended nor needed anymore.

The AR5416_VER_MASK macro does the same as get_eeprom_rev, except that
one has to know the actual EEPROM type (and providing a reference to
that in a variable named "eep"). Additionally the eeprom_*.c
implementations used the same shifting logic multiple times to get the
eeprom revision which was also unnecessary duplication of
get_eeprom_rev.
Also use the AR5416_EEP_VER_MINOR_MASK macro where needed and introduce
a similar macro (AR5416_EEP_VER_MAJOR_MASK) for the major version.
Finally drop AR9287_EEP_VER_MINOR_MASK since it simply duplicates the
already defined AR5416_EEP_VER_MINOR_MASK.

The eepMisc field was not set explicitly. The default value of 0 means
that the values in the EEPROM (template) should be interpreted as little

With maximum number of vap's configured in a two radio supported
systems of ~256 Mb RAM, doing a continuous wifi down/up and
intermittent traffic streaming from the connected stations results
in failure to allocate contiguous memory for tx buffers. This results
in the disappearance of all VAP's and a manual reboot is needed as
this is not a crash (or) OOM(for OOM killer to be invoked). To address
this allocate contiguous memory for tx buffers one time and re-use them
until the modules are unloaded but this results in a slight increase in
memory footprint of ath10k when the wifi is down, but the modules are
still loaded. Also as of now we use a separate bool 'tx_mem_allocated'
to keep track of the one time memory allocation, as we cannot come up

During firmware crash (or) user requested manual restart
the system gets into a soft lock up state because of the
below root cause.
During user requested hardware restart / firmware crash
the system goes into a soft lockup state as 'napi_synchronize'
is called after 'napi_disable' (which sets 'NAPI_STATE_SCHED'
bit) and it sleeps into infinite loop as it waits for
'NAPI_STATE_SCHED' to be cleared. This condition is hit because
'ath10k_hif_stop' is called twice as below (resulting in calling
'napi_synchronize' after 'napi_disable')
'ath10k_core_restart' -> 'ath10k_hif_stop' (ATH10K_STATE_ON) ->
-> 'ieee80211_restart_hw' -> 'ath10k_start' -> 'ath10k_halt' ->
'ath10k_core_stop' -> 'ath10k_hif_stop' (ATH10K_STATE_RESTARTING)
Fix this by calling 'ath10k_halt' in ath10k_core_restart itself
as it makes more sense before informing mac80211 to restart h/w
Also remove 'ath10k_halt' in ath10k_start for the state of 'restarting'

Radar pulse and spectral scan reports are provided by the HW
with the ATH9K_RXERR_PHY flag set. Those are forwarded to
the dfs-detector and spectral module for further processing.
For some older chips, the pre-conditions checked in those
modules are ambiguous, since ATH9K_PHYERR_RADAR is used to
tag both types. As a result, spectral frames are fed into
the dfs-detector and vice versa.
This could lead to a false radar detection on a non-DFS
channel (which is uncritical), but more relevant it causes
useless CPU load for processing invalid frames.
This commit ensures that the dfs-detector and spectral
collector are only fed when they are active.

changing the return on success from 1 to BIT(gpio). This broke some callers
like ath_is_rfkill_set(). This doesn't fix any known bug in mainline at the
moment, but should be fixed anyway.
Instead of fixing all callers, change ath9k_hw_gpio_get() back to only
return 0 or 1.

- set_tsf assumed a simple offset was applied against
get_tsf(), which works, except in the case of

Current set_tsf is implemented in terms of TSF_INCREMENT

export these through offset_tsf. Advantage is we get
more accurate TSF adjustments, and don't calculate wrong
offset in case absolute TSF was calculated from rx_mactime
(actual TSF).
The new WMI command is available in firmware

Indicate hardware (or firmware) supports that CQM packet-loss report
will be generated based on station kickout algorithm. As of now mac80211
tracks connection loss by missing msdu counts (50) whereas ath10k
firmware tracks them by missing ppdus (+ BAR tries). While firmware is
trying to adapt its rate table, mac80211 might send out low_ack event to
hostapd. This is causing frequent connect and disconnect iteration under
noisy environment or when station is roaming around.

ath.git patches for 4.10. Major changes:
ath9k
* add device tree bindings
* switch to use mac80211 intermediate software queues to reduce
latency and fix bufferbloat
The hostap_80211_rx() function is supposed to set up the mac addresses
for four possible cases, based on two bits of input data. For
some reason, gcc decides that it's possible that none of the these
four cases apply and the addresses remain uninitialized:
drivers/net/wireless/intersil/hostap/hostap_80211_rx.c: In function ‘hostap_80211_rx’:
arch/x86/include/asm/string_32.h:77:14: warning: ‘src’ may be used uninitialized in this function [-Wmaybe-uninitialized]
drivers/net/wireless/intel/ipw2x00/libipw_rx.c: In function ‘libipw_rx’:
arch/x86/include/asm/string_32.h:77:14: error: ‘dst’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
arch/x86/include/asm/string_32.h:78:22: error: ‘*((void *)&dst+4)’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
This warning is clearly nonsense, but changing the last case into
'default' makes it obvious to the compiler too, which avoids the
warning and probably leads to better object code too.
The same code is duplicated several times in the kernel, so this
patch uses the same workaround for all copies. The exact configuration
was hit only very rarely in randconfig builds and I only saw it
in three drivers, but I assume that all of them are potentially
affected, and it's better to keep the code consistent.

This switches ath9k over to using the mac80211 intermediate software
queueing mechanism for data packets. It removes the queueing inside the
driver, except for the retry queue, and instead pulls from mac80211 when
a packet is needed. The retry queue is used to store a packet that was
pulled but can't be sent immediately.
The old code path in ath_tx_start that would queue packets has been
removed completely, as has the qlen limit tunables (since there's no
longer a queue in the driver to limit).
The mac80211 intermediate software queues offer significant latency
reductions, and this patch allows ath9k to realise them. The exact gains
from this varies with the test scenario, but in an access point scenario
we have seen latency reductions ranging from 1/3 to as much as an order
of magnitude. We also achieve slightly better aggregation.
Median latency (ping) figures with this patch applied at the access point,
with two high-rate stations and one low-rate station (HT20 5Ghz), running
a Flent rtt_fair_var_up test with one TCP flow and one ping flow going to
each station:
Fast station Slow station
Default pfifo_fast qdisc: 430.4 ms 638.7 ms
fq_codel qdisc on iface: 35.5 ms 211.8 ms
This patch set: 22.4 ms 38.2 ms
Median aggregation sizes over the same test:
Default pfifo_fast qdisc: 9.5 pkts 1.9 pkts
fq_codel qdisc on iface: 11.2 pkts 1.9 pkts
This patch set: 13.9 pkts 1.9 pkts
This patch is based on Tim's original patch set, but reworked quite
thoroughly.

The active_high LED of my Wistron DNMA-92 is still being recognized as
active_low on 4.7.6 mainline. When I was preparing my former commit
0f9edcdd88 ("ath9k: Fix LED polarity for some Mini PCI AR9220 MB92
cards.") to fix that I must have somehow messed up with testing, because
I tested the final version of that patch before sending it, and it was
apparently working; but now it is not working on 4.7.6 mainline.
I initially added the PCI_DEVICE_SUB section for 0x0029/0x2096 above the
PCI_VDEVICE section for 0x0029; but then I moved the former below the
latter after seeing how 0x002A sections were sorted in the file.
This turned out to be wrong: if a generic PCI_VDEVICE entry (that has
both subvendor and subdevice IDs set to PCI_ANY_ID) is put before a more
specific one (PCI_DEVICE_SUB), then the generic PCI_VDEVICE entry will
match first and will be used.
With this patch, 0x0029/0x2096 has finally got active_high LED on 4.7.6.
While I'm at it, let's fix 0x002A too by also moving its generic definition
below its specific ones.

The old WDS 4-addr frame support is very limited, e.g.
* no encryption is possible on such links
* it cannot support rate/HT/VHT negotiation
* management APIs are very restricted
These make the WDS legacy mode useless in practice.
All of these are resolved by the 4-addr AP/client support,
so there's also no reason to improve WDS in the future.
Therefore, add a Kconfig option to disable legacy WDS.
This gives people an "emergency valve" while they migrate
to the better-supported 4-addr AP/client option; we plan
to remove it (and the associated cfg80211/mac80211 code,
which is the ultimate goal) in the future.

Currently mac80211 determines whether HW does fragmentation
by checking whether the set_frag_threshold callback is set
or not.
However, some drivers may want to set the HW fragmentation
capability depending on HW generation.
Allow this by checking a HW flag instead of checking the
callback.

Commit 0b8e3c4ca2 ("ath10k: move cal data len to hw_params") broke retrieving
the calibration data from cal_data debugfs file. The length of file was always
zero. The reason is:
static ssize_t ath10k_debug_cal_data_read(struct file *file,
char __user *user_buf,
size_t count, loff_t *ppos)
{
struct ath10k *ar = file->private_data;
void *buf = file->private_data;
This is obviously bogus, private_data cannot contain both struct ath10k and the
buffer. Fix it by caching calibration data to ar->debug.cal_data. This also
allows it to be accessed when the device is not active (interface is down).
The cal_data buffer is fixed size because during the first firmware probe we
don't yet know what will be the lenght of the calibration data. It was simplest
just to use a fixed length. There's a WARN_ON() in
ath10k_debug_cal_data_fetch() if the buffer is too small.
Tested with qca988x and firmware 10.2.4.70.56.

Unfortunately ath10k does not generally allow modifying the coverage class
with the stock firmware and Qualcomm has so far refused to implement this
feature so that it can be properly supported in ath10k. If we however know
the registers that need to be modified for proper operation with a higher
coverage class, then we can do these modifications from the driver.
This is a hack and might cause subtle problems but as it's not enabled by
default (only when user space changes the coverage class explicitly) it should
not cause new problems for existing setups. But still this should be considered
as an experimental feature and used with caution.
This patch implements the support for first generation cards (QCA9880, QCA9887
and so on) which are based on a core that is similar to ath9k. The registers
are modified in place and need to be re-written every time the firmware sets
them. To achieve this the register status is verified after certain WMI events
from the firmware.
The coverage class may not be modified temporarily right after the card
re-initializes the registers. This is for example the case during scanning.
Thanks to Sebastian Gottschall <s.gottschall@dd-wrt.com> for initially
working on a userspace support for this. This patch wouldn't have been

Firmware is running watchdog timer for tracking copy engine ring index
and write index. Whenever both indices are stuck at same location for
given duration, watchdog will be trigger to assert target. While
updating copy engine destination ring write index, driver ensures that
write index will not be same as read index by finding delta between these
two indices (CE_RING_DELTA).
HTT target to host copy engine (CE5) is special case where ring buffers
will be reused and delta check is not applied while updating write index.
In rare scenario, whenever CE5 ring is full, both indices will be referring
same location and this is causing CE ring stuck issue as explained
above. This issue is originally reported on IPQ4019 during long hour stress
testing and during veriwave max clients testsuites. The same issue is
also observed in other chips as well. Fix this by ensuring that write
index is one less than read index which means that full ring is
available for receiving data.

In QCA99X0 (QCA99X0, QCA9984, QCA9888 and QCA4019) family chips,
hw adds padding at the begining of the rx payload to make L3
header 4-byte aligned. In the chips doing this type of padding,
the number of bytes padded will be indicated through msdu_end:info1.
Define a hw_rx_desc_ops wrapper to retrieve the number of padded
bytes and use this while doing undecap. This should fix padding
related issues with ethernt decap format with QCA99X0, QCA9984,
QCA9888 and QCA4019 hw.

There are slight differences in Rx hw descriptor information
among different chips. So far driver does not use those new
information for any functionalities, but there is one important
information which is available from QCA99X0 onwards to indicate
the number of bytes that hw padded at the begining of the rx
payload and this information is needed to undecap the rx
packet. Add an abstraction for Rx desc to make use of the
new desc information available. The callback that this patch
defines to retrieve the padding bytes will be used in follow-up
patch.

carl9170_usb_stop() is used from several places to flush and cleanup any
pending work. The normal pattern is to send a request and wait for the
irq handler to call complete(). The completion is not reinitialized
during normal operation and as the old comment indicates it is important
to keep calls to wait_for_completion_timeout() and complete() balanced.
Calling complete_all() brings this equilibirum out of balance and needs
to be fixed by a reinit_completion(). But that opens a small race
window. It is possible that the sequence of complete_all(),
reinit_completion() is faster than the wait_for_completion_timeout() can
do its work. The wake up is not lost but the done counter test is after
reinit_completion() has been executed. The only reason we don't see
carl9170_exec_cmd() hang forever is we use the timeout version of
wait_for_copletion().
Let's fix this by reinitializing the completion (that is just setting
done counter to 0) just before we send out an request. Now,
carl9170_usb_stop() can be sure a complete() call is enough to make
progess since there is only one waiter at max. This is a common pattern
also seen in various drivers which use completion.

The ath6kl driver attempts to get the txpower value from the radio by first
clearing the existing stored value and then watching the value to become
non-zero.
APs allow setting client power to values from -127..127, but this radio
is not capable of setting values less then 0 and so will report txpower
as 0dbm for both negative and 0 client power values.
When the radio has txpower set to 0dbm txpower (equivalent to 1mw) the
ath6kl_cfg80211_get_txpower() function will remain in the
wait_event_interruptible_timeout() loop waiting for the value to be
non-zero, and will eventually timeout. This results in a 5 second delay in
response. However, the correct value of zero is eventually returned.
The 6004 defaults to 63dbm which is then limited by regulatory and
hardware limits with max of 18dbm (6003 max is 16dbm), therefore we can
use values larger then these to be able to determine when the value has
been updated.
To correct the issue, set the value to a nonsensical value (255) and wait
for it to change to the valid value.
Tested on both 6003 and 6004 based radios. Return value of zero is
correctly returned in an expected amount of time (similar to when
returning non-zero values) when AP client power is set to both 0 and
negative values.

commit 7a0adc83f3 ("ath10k: improve tx scheduling") is causing
severe throughput drop in multi client mode. This issue is originally
reported in veriwave setup with 50 clients with TCP downlink traffic.
While increasing number of clients, the average throughput drops
gradually. With 50 clients, the combined peak throughput is decreased
to 98 Mbps whereas reverting given commit restored it to 550 Mbps.
Processing txqs for every tx completion is causing overhead. Ideally for
management frame tx completion, pending txqs processing can be avoided.
The change partly reverts the commit "ath10k: improve tx scheduling".
Processing pending txqs after all skbs tx completion will yeild enough
room to burst tx frames.

Add NAPI support for rx and tx completion. NAPI poll is scheduled
from interrupt handler. The design is as below
- on interrupt
- schedule napi and mask interrupts
- on poll
- process all pipes (no actual Tx/Rx)
- process Rx within budget
- if quota exceeds budget reschedule napi poll by returning budget
- process Tx completions and update budget if necessary
- process Tx fetch indications (pull-push)
- push any other pending Tx (if possible)
- before resched or napi completion replenish htt rx ring buffer
- if work done < budget, complete napi poll and unmask interrupts
This change also get rid of two tasklets (intr_tq and txrx_compl_task).
Measured peak throughput with NAPI on IPQ4019 platform in controlled
environment. No noticeable reduction in throughput is seen and also

In the wake tx queue path, we are not checking if the frame to be sent
takes management path or not. For eg. QOS null func frame coming here will
take the management path. Since we are not incrementing the descriptor
counter (num_pending_mgmt_tx) w.r.t tx management, on tx completion it is
possible to see negative values.
When the above counter reaches a negative value, we will not be sending a
probe response out.
if (is_presp &&

For IPQ4019, max_probe_resp_desc_thres (u32) is 24 is compared against
num_pending_mgmt_tx (int) and the above condtions comes true if the counter
is negative and we drop the probe response.

txqs_lock is interfering with wake_tx_queue submitting more frames.
so queues don't get filled in and don't keep firmware/hardware busy
enough. This change helps to reduce the txqs_lock contention and
wake_tx_queue() blockage to being possible in txrx_unref().
To reduce turn around time of wake_tx_queue ops and to maintain fairness
among all txqs, the callback is updated to push first txq alone from
pending list for every wake_tx_queue call. Remaining txqs will be
processed later upon tx completion.
Below improvements are observed in push-only mode and validated on
IPQ4019 platform. With this change, in AP mode ~10Mbps increase is
observed in downlink (AP -> STA) traffic and approx. 5-10% of CPU
usage is reduced.
Major improvement is observed in 1-hop Mesh mode topology in 11ACVHT80.
Compared to Infra mode, CPU overhead is higher in Mesh mode due to path
lookup and no fast-xmit support. So reducing spin lock contention is
helping in Mesh.

HW Rx filters and masks are not configured
properly by firmware during boot sequences. The
MAC_PCU_ADDR1 is set to 0s instead of 1s which
allows the HW to ACK any frame that passes through
MAC_PCU_RX_FILTER. The MAC_PCU_RX_FILTER itself
is misconfigured on boot as well.
The combination of these bugs ended up with the
following manifestations:
- "no channel configured; ignoring frame(s)!"
warnings in the driver
- spurious ACKs (transmission) on the air during
firmware bootup sequences
The former was a long standing and known bug
originally though mostly harmless.
However Marek recently discovered that this
problem also involves ACKing *all* frames the HW
receives (including beacons ;). Such frames
are delivered to host and generate the former
warning as well.
This could be a problem with regulatory compliance
in some rare cases (e.g. Taiwan which forbids
transmissions on channel 36 which is the default
bootup channel on 5Ghz band cards). The good news
is that it'd require someone else to violate
regulatory first to coerce our device to generate
and transmit an ACK.
The problem could be reproduced in a rather busy
environment that has a lot of APs. The likelihood
could be increased by injecting an msleep() of
5000 or longer immediately after
ath10k_htt_setup() in ath10k_core_start().
The reason why the former warnings were only
showing up seldom is because the device was either
quickly reset again (i.e. during firmware probing)
or wmi vdev was created (which fixes hw and fw
states).
It is technically possible for host driver to
override adequate hw registers however this can't
work reliably because the bug root cause lies in
incorrect firmware state on boot (internal
structure used to program MAC_PCU_ADDR1 is not
properly initialized) and only vdev create/delete
events can fix it. This is why the patch takes
dummy vdev approach.
This could be fixed in firmware as well but having
this fixed in driver is more robust, most notably
when thinking of users of older firmware such as
999.999.0.636.

The use of config_enabled() against config options is ambiguous. In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED(). Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention
clearer.
This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.
I noticed two cases where config_enabled() is used against a tristate
option:
- config_enabled(CONFIG_HWMON)
[ drivers/net/wireless/ath/ath10k/thermal.c ]
- config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
[ drivers/gpu/drm/gma500/opregion.c ]
I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

When enabling WLAN tethering, a new AP is visible and a STA could
connect to it. When the STA tries to authenticate to the newly created
AP, the WPA authentication mechanism is stuck in the 1/4 msg of 4-Way
Handshake.
In ath6kl_rx(), the ath6kl_find_sta() function is looking for the
h_source field of the Ethernet frame header received by the STA. The
datap pointer that points to the Ethernet frame header is incorrect,
and was pointing at the wrong offset in the buffer.
This commit adds a pad_before_data_start offset to set the datap pointer

This patch fixes some issues with interface reconfiguration. It could
for example happen that an AP interface in beacon slot 0 was removed
leaving an IBSS station in one of the other slots. When this happens
the driver never sends out the beacon as it only tries to send a beacon
from slot 0.
Appart from that the tracking of required changes to the beacon config is
relatively complicated and prone to errors.
The approach taken here is to solve reconfiguration issues is to
reconfigure the beacons when any interface changes. This means that
the complexity of deciding whether an interface change may modify the
beacon configuration is gone. It also means that the beacon config will
be reliably updated when an interface is removed.
The issue that a single non-AP interface might not be in beacon
slot 0 and wouldn't be send out is solved by moving it into the
first slot. The TSF value in hardware is adjusted accordingly so
that the timestamp of the beacons stay consistent.

Beacons were not send out at (timestamp % beacon_time == 0) for interfaces
other than the primary one. To send out beacons with the correct timestamp
according to 10.1.3.2 of the 802.11 standard the tsf_adjustment has to be
set to the negative time difference instead of positive. This way the
later beacons get corrected to have a lower (and similar) timestamp with
regard to the beacon from slot 0.

It is expected that all pktlog events for 10.4 firmware based solutions
should come through CE8 where as in case of 10.2 firmware based solutions,
it should come through one of the HTT events (HTT_T2H_MSG_TYPE_PKTLOG).
But from experiments with 10.4 based solutions, it is observed that pktlog
event for ATH_PKTLOG_TYPE_TX_MSDU_ID is coming through HTT pktlog event.
Currently, we always parse with 10.2 pktlog header which will lead to
pktlog decoding issues (payload length mismatch exceptions)
For trace points, it is required to provide only the payload size. So
fixing this by simplifying the payload size calculation without the use of
ath10k pktlog headers.

Add the following to support beacon report radio measurement
with the measurement mode field set to passive or active:
1. Propagate the required scan duration to the device
2. Report the scan start time (in terms of TSF)
3. Report each BSS's detection time (also in terms of TSF)
TSF times refer to the BSS that the interface that requested the
scan is connected to.

Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.
In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.
Supporting beacon report is required for Multi Band Operation (MBO).

The below warning message seems to hit occasionally with the following
combination (IPQ4019 + ACS scan) where we receive packets as a self peer
when hostapd does ACS when we bring up AP mode . ath10k has the below
fall back mechanism to fetch current operating channel in rx (it will
check for the next channel tracking variable if the current one is NULL)
[scan channel] --> [rx channel] --> [peer channel] -->
[vdev channel] --> [any vdev channel] --> [target oper channel]
'scan channel' and 'target operating channel' are directly fetched from
firmware events. All the others should be updated by mac80211.
During ACS scan we wouldn't have a valid channel context
assigned from mac80211 ('ar->rx_channel'), and also relying on
('ar->scan_channel') is not helpful (it becomes NULL when it goes to
BSS channel and also when the scan event is completed). In short we
cannot always rely on these two channel tracking variables.
'Target Operating Channel' (ar->tgt_oper_chan) seems to keep track of
the current operating even while we are doing ACS scan and etc. Hence
remove this un-necessary warning message and continue with
target_operating channel. At the worst case scenario when the target
operating channel is invalid (NULL) we already have an ath10k warning
message to notify we really don't have a proper channel configured in
rx to update the rx status("no channel configured; ignoring frame(s)!")

Usually when the firmware crashes we check for the value
'FW_IND_EVENT_PENDING' in 'FW_INDICATOR_ADDRESS' and proceed with
disabling the irq and dumping firmware 'crash dump'. Now
when the PCI card is unplugged from the device the PCI controller
seems to generate a spurious interrupt after some time which
was as treated a firmware crash and resulting in the below race
condition (and eventually crashing the system)
ath10k_core_unregister -> ath10k_core_free_board_files
...... device unplug spurious interrupt .........
ath10k_pci_taklet -> ath10k_pci_fw_crashed_dump ...etc
Clearly even after the firmware board files related data structure
is freed up we are getting a spurious interrupt from PCI with 0xfffffff
in the 'FW_INDICATOR_ADDRESS' resulting in scheduling of the pci tasklet
and doing a crash dump, printing f/w board related info resulting in the
below crash. Fix this by detecting this spurious interrupt in ath10k PCI
irq handler itself and return IRQ_NONE. Thanks to Michal Kazior for
helping us conclude the most appropriate fix.

The nl80211 layer expects P2P search operation to be aborted
if needed when stopping P2P device. If the P2P search operation
is still running after returning from stop_p2p_device
it causes a WARN_ON and possibly a kernel crash.
Fix this by aborting the P2P search in wil_cfg80211_stop_p2p_device
and preventing P2P search from being started on a stopped P2P
device.
Note, the fix does not cover the case where a regular scan
is started on the P2P device. It will be completed in the

In QCA4019, cycle counter wraparound is not tied to rx
clear counter. Each counter would wraparound individually
and after wraparound the respective counter will be reset
to 0x7fffffff while other counter still running unaffected.
Define a new wraparound type for this behaviour and handle
it separately so that rx clear counter wraparound is also
handled just like cycle counter. With this type of

There are 2 possible race conditions, both are solved by addition of

1. wil_tx_complete reads the swhead to determine if the vring is
empty. In case the swhead was updated before the descriptor update
was performed in __wil_tx_vring/__wil_tx_vring_tso, the completion
loop will not end and as the DU bit may still be set from a previous
run, this skb can be handled as completed before it was sent, which
will lead to double free of the same SKB.
2. __wil_tx_vring/__wil_tx_vring_tso calculate the number of available
descriptors according to the swtail. In case the swtail is updated
before memset of ctx to zero is completed, we can handle this
descriptor while later on ctx is zeroed.

WARN_ON_ONCE when we receive packets for self peer when mac80211
had not assigned a proper channel context. This scenario happens
in QCA4019 when we start the AP via hostapd in background and start
it once again in the background without killing the previous instance!
This happens intermittently when we start / stop hostapd in a while loop
(incase the hostapd is not properly killed). This results in mac80211
chancontext to be unassigned, while the self peer continuous receive
packets in target operating channel. This results in lot of call traces
in the rx path. Make this as a WARN_ON_ONCE to avoid flooding the console
which result in rebooting low memory systems, while still reporting the
warning once that we are receiving packets in target operating channel and
to indicate that something is happening which is not the expected result.

Store pci chip secific reset funtions in struct ath10k_pci

adds two callback in ath10k_pci, one for doing soft reset and

During hw scan, firmware sends two channel information events (pre-
complete, complete) to host for each channel change. The snap shot of cycle
counters (rx_clear and total) between these two events are given for
survey dump. In order to get latest survey statistics of all channels, a
scan request has to be issued. In general, an AP DUT is brought up, it
won't leave BSS channel except few cases like overlapping bss or radar
detection. So survey statistics of bss channel is always referring to
older data that are collected before starting AP (either ACS/OBSS scan).
To collect latest survey information from target, firmware provides WMI
interface to read cycle counters from hardware. For each survey dump
request, BSS channel cycle counters are read and cleared in hardware.
This makes sure that behavior is in align with ath9k survey report.
So survey dump always gives snap shot of cycle counters b/w two survey
requests.

According to the spec, VHT doesn't exist in 2.4GHz.
There are vendor extensions to allow a subset of VHT to work
(notably 256-QAM), but since mac80211 doesn't support those
advertising VHT capability on 2.4GHz leads to the behaviour
of reporting VHT capabilities but not being able to use any
of them due to mac80211's code requiring 80 MHz support.
Remove the VHT capabilities from 2.4GHz for now. If mac80211
gets extended to use the (likely Broadcom) vendor IEs for it
and handles the lack of 80 MHz support, it can be added back.

In idle times 60G device can enter deep sleep and turn off
its XTAL clock.
Host access triggers the device power-up flow which will hold
the AHB during XTAL stabilization until device switches from
slow-clock to XTAL clock.
This behavior can stall the PCIe bus for some arbitrary period
of time.
In order to prevent this stall, host can vote for High Latency
Access Policy (HALP) before reading from PCIe bus.
This vote will wakeup the device from deep sleep and prevent
deep sleep until unvote is done.

current txpower limit in the regulatory, but not
against the user set value. It ensures that the
resulting EIRP is below the limit defined by the
active countrycode, but not below the value the
user requested.
In a scenario like e.g.
a) antenna_gain=6
b) countrycode limits to eirp=18
c) user set txpower=15
this will cause a setting for AR_PHY_POWER_TX_RATE
regs resulting in an EIRP > 15.
This patch ensures that antenna-gain is considered
whenever the txpower limit is adjusted and with that
the user set limits are kept.

push-pull mode needs certain amount the host driver involvement for
managing queues in the host memory and packet delivery to firmware.
qca4019 wifi firmware has an option to stay in push mode for less
number of active traffic flow and then switch to push-pull mode when
the active traffic flow goes beyond the certain limit.
The advantage of staying in push mode for less active traffic is, the
host cpu consumption is reduced. qca4019 firmware supports this
flexibility of the mode switch. It takes the host driver interest
(LOW_PERF/HIGH_PERF) via WMI_EXT_RESOURCE_CFG_CMDID,
LOW_PERF - fw would stay in push mode and switch to push-pull
based on demand.
HIGH_PERF - fw would stay in push-pull mode from the boot.
To make this configuration generic, new WMI services
WMI_SERVICE_TX_MODE_PUSH_ONLY, WMI_SERVICE_TX_MODE_PUSH_PULL,
WMI_SERVICE_TX_MODE_DYNAMIC are introduced to take dynamic tx mode
switch support availability in firmware.
Based on WMI_SERVICE_TX_MODE_DYNAMIC, LOW_PERF or HIGHT_PERF is
configured to the firmware.

Whenever htt rx indication i.e target to host messages are received
on rx copy engine (CE5), the message will be freed after processing
the response. Then CE 5 will be refilled with new descriptors at
post rx processing. This memory alloc and free operations can be avoided
by reusing the same descriptors.
During CE pipe allocation, full ring is not initialized i.e n-1 entries
are filled up. So for CE 5 full ring should be filled up to reuse
descriptors. Moreover CE 5 write index will be updated in single shot
instead of incremental access. This could avoid multiple pci_write and
ce_ring access. From experiments, It improves CPU usage by ~3% in IPQ4019

qca4019 calibration data is stored in the host memory and it's mandatory
to download it even before reading board id and chip id from the target.
Also, there is a need to execute otp (download and run) twice, one after
cal data download and another one after board data download.
Existing cal data file name 'cal-<bus>-<id>.bin' and device tree entry
'qcom,ath10k-calibration-data' used in ath10k has assumption that it
carries other data (like board data) also along with the calibration data.
But, qca4019 cal data contains pure calibration data (doesn't include
any other info). So, using existing same cal file name and DT entry
in qca4019 case would alter the purpose of it. To avoid this, new cal
file name 'pre-cal-<bus>-<id>.bin' and new device tree entry name
'qcom,ath10k-pre-calibration-data are introduced.
Overall qca4019's firmware download sequence would look like,
1) Download cal data (either from a file or device tree entry)
at the address specified by target in the host interest area
member "hi_board_data".
2) Download otp and run with 0x10 (PARAM_GET_EEPROM_BOARD_ID)
as a argument.
At this point, otp will take back up of downloaded cal data
content in another location in the target and return valid
board id and chip id to the host.
3) Download board data at the address specified by target
in host interest area member "hi_board_data".
4) Download otp and run with 0x10000 (PARAM_FLASH_SECTION_ALL) as
a argument.
Now otp will apply cal data content from it's backup on top
of board data download in step 3 and prepare final data base.
5) Download code swap and athwlan binary content.
Above sequences are implemented (step 1 to step 4) in the name of
pre calibration configuration.

against QCA988X_CAL_DATA_LEN (2116 bytes). It was written by keeping
qca988x in mind. In fact, cal data length is more chip specific.

Both ath10k_download_cal_file() and ath10k_download_cal_dt() uses
hard coded file pointer (ar->cal_file) and device tree entry
(qcom,ath10k-calibration-data) respectively to get calibration
data content.
There is a need to use those two functions in qca4019 calibration
download sequence with different file pointer and device tree entry name.
Modify those two functions to take cal data location as an argument.
So that it can serve the purpose for other file pointer and device
tree entry.

not for mgmt frames per se. In 16 MBSSID scenario, these reserved slots
will be easy exhausted due to frequent probe responses. So for 10.4
based solutions, probe responses are limited by a threshold (24).
management tx path is separate for all except tlv based solutions. Since
tlv solutions (qca6174 & qca9377) do not support 16 AP interfaces, it is
safe to move management descriptor limitation check under mgmt_tx
function. Though CPU improvement is negligible, unlikely conditions or
never hit conditions in hot path can be avoided on data transmission.

Whenever firmware is configuring operating channel during scan or
home channel, channel change event will be indicated to host. In some
cases (device probe/ last vdev down), target will be configured to
default channel whereas host is unaware of target's operating channel.
This leads to packet drop due to unknown channel and kernel log will be
filled up with "no channel configured; ignoring frame(s)!". Fix that
by handling HTT_T2H_MSG_TYPE_CHAN_CHANGE event.

Code that was added back in 2.6.38 has an obvious overflow
when accessing a static array, and at the time it was added
only a code comment was put in front of it as a reminder
to have it reviewed properly.
This has not happened, but gcc-6 now points to the specific
overflow:

Certain 6004 firmware releases redefine the WMI_TXE_NOTIFY_EVENTID event
number and sends the new event frequently. However it doesn't have the

the firmware package. By guarding the processing of this event by the same
method we guard the sending of the WMI_SET_TXE_NOTIFY_CMDID command, we
can ignore the spurious event that we don't know how to process.

Added support for the P2P_DEVICE virtual interface. This interface
is intended for P2P management operations such as discovery and
GO negotiation. Normally it is implemented by drivers to allow
a separate interface for P2P management with its own MAC address,
but for 11ad drivers it is needed to support P2P search, since it
cannot otherwise be separated from normal scan.
Since we only support a single interface/MAC address, we can't
easily separate between primary and P2P_DEVICE interfaces.
For example when a management packet arrives we can't tell for
which interface it is intended. To work around this, we store
a pointer to the interface where the last "radio operation" was
triggered such as scan or remain on channel, and we forward
management packets and scan results to this interface.

PBSS (Personal Basic Service Set) is a new BSS type for DMG
networks. It is similar to infrastructure BSS, having an AP-like
entity called PCP (PBSS Control Point), but it has few differences.
For example, stations inside a PBSS can communicate directly, and
the PCP role can be transferred between stations.
This change adds PBSS support, and has 2 main parts:
1. When starting an AP, add an option to start as a PCP instead.
This is implemented by a new PBSS flag which is passed as part of

This allows sending the RX and TX BACK commands from the WMI event

This is a better approach as it can decrease the handshake time
in the connect flow and prevent race conditions in case of fast
disconnects. An example for such a race is handling of wil_back_rx_handle

The current/old tx path design was that host, at
its own leisure, pushed tx frames to the device.
For HTT there was ~1000-1400 msdu queue depth.
After reaching that limit the driver would request
mac80211 to stop queues. There was little control
over what packets got in there as far as
DA/RA was considered so it was rather easy to
starve per-station traffic flows.
With MU-MIMO this became a significant problem
because the queue depth was insufficient to buffer
frames from multiple clients (which could have
different signal quality and capabilities) in an
efficient fashion.
Hence the new tx path in 10.4 was introduced: a
pull-push mode.
Firmware and host can share tx queue state via
DMA. The state is logically a 2 dimensional array
addressed via peer_id+tid pair. Each entry is a
counter (either number of bytes or packets. Host
keeps it updated and firmware uses it for
scheduling Tx pull requests to host.
This allows MU-MIMO to become a lot more effective
with 10+ clients.

Firmware 10.4.3 onwards can support a pull-push Tx
model where it shares a Tx queue state with the

The host updates the DMA region it pointed to
during HTT setup whenever number of software
queued from (on host) changes. Based on this
information firmware issues fetch requests to the
host telling the host how many frames from a list
of given stations/tids should be submitted to the
firmware.
The code won't be called because not all

The pull-push functionality of 10.4 will be based
on peer_id and tid. These will need to be mapped,
eventually, to ieee80211_txq to be used with
ieee80211_tx_dequeue().
Iterating over existing stations every time
peer_id needs to be mapped to a station would be
inefficient wrt CPU time.
The new firmware, which will be the only user of
the code flow-wise, will guarantee to use low
peer_ids first so despite peer_map's apparent huge
size d-cache thrashing should not be a problem.

Tx pending counter logic assumed that the sk_buff
is already known and hence was performed in HTT

However, for the sake of future wake_tx_queue()
usage the driver must be able to tell whether it
can submit more frames to firmware before it
dequeues frame from ieee80211_txq (and thus long
before HTT Tx functions are called) because once a

In some configurations, this function uses more than the warning limit
of 1024 bytes:
drivers/net/wireless/ath/ath9k/ar9003_aic.c: In function 'ar9003_aic_cal_post_process':

It turns out that there are two large arrays on the stack here, but
almost all the data in them is never used outside of the loop in
which it gets written, so we can replace the array with a single
instance.
The .valid flag is used later, so I'm replacing the array of structures
with an array of bools. An obvious follow-up optimization would be
to replace it with a bitmask and set_bit()/find_first_bit()/
find_last_bit()/... operations. However, I have not tested this patch,
so I sticked to the simpler transformation that does the job of
reducing the stack usage to a harmless level.

To enable per peer stats feature we are reducing the number of peers.
Firmware has introduced tx stats feature. We have memory limitation in
firmware to add these additional bytes.
These are the new variables introduced in the firmware.
======== =======================
Variable Bytes required/per rate
======== =======================
TX success packets 1
TX failed packets 1
Retry packets 1
Success bytes 2
TX failed bytes 2
Retry bytes 2
Tx duration 4
Rate 1
Bw and AMPDU flags 1
Total 16 (because of allocation in word pattern)
Firmware sends these tx_stats in pktlog.
If we consider 4 feedbacks at a time, Frimware need about ~1K memory for coding
and 8192 bytes required / per rate [ 4*16*128(peers)].
To accommodate this firmware needs to reduce 10 peers.

qca4019 uses ahb instead of pci where it slightly differs in device
enumeration, clock control, reset control, etc. Good thing is that
ahb also uses copy engine for the data transaction. So, the most of
the stuff implemented in pci.c/ce.c are reusable in ahb case too.
Device enumeration in ahb case comes through platform driver/device
model. All resource details like irq, memory map, clocks, etc for
qca4019 can be fetched from of_node of platform device.
Simply flow would look like,
device tree => platform device (kernel) => platform driver (ath10k)
Device tree entry will have all qca4019 resource details and the same
info will be passed to kernel. Kernel will prepare new platform device
for that entry and expose DT info to of_node in platform device.
Later, ath10k would register platform driver with unique compatible name
and then kernels binds to corresponding compatible entry & calls ath10k
ahb probe functions. From there onwards, ath10k will take control of it
and move forward.
New bool flag CONFIG_ATH10K_AHB is added in Kconfig to conditionally
enable ahb support in ath10k. On enabling this flag, ath10k_pci.ko
will have ahb support. This patch adds only basic skeleton and few

There is a plan to use most of stuff available in pci.c

of pci wake/sleep for every read/write is not required
in AHB case (qca4019). All those reusable areas in pci.c

read and write.
In fact, ath10k_pci_read32/write32() should do what it does
today for PCI case. But for AHB, it has to do differently.
To make ath10k_pci_read32/write32() more generic, new function
pointers are added in ar_pci for the function which does
operation more close to the bus. Later, corresponding bus
specific read and write function will be mapped to that.

Warm Reset trigger in continuous beacon stuck for one of the customer for
other chip, noticed the MAC was stuck in RTC reset. After analysis noticed
DMA did not complete when RTC was put in reset.
So, before resetting the MAC need to make sure there are no pending DMA
transactions because this reset does not reset all parts of the chip.
The 12th and 11th bit of MAC _DMA_CFG register used to do that.
12 cfg_halt_ack 0x0
0 DMA has not yet halted
1 DMA has halted
11 cfg_halt_req 0x0
0 DMA logic operates normally
1 Request DMA logic to stop so software can reset the MAC
The Bit [12] of this register indicates when the halt has taken effect or
not. the DMA halt IS NOT recoverable; once software sets bit [11] to
request a DMA halt, software must wait for bit [12] to be set and reset
the MAC.

In the start_ap/change_beacon API, when we set up probe response
offloading, we only use the IE list from the probe response
template and not the IE list from the proberesp_ies argument.
As a result, we miss important IEs and it causes problems with
some scenarios such as P2P.
With this change, we merge the list of IEs from the probe response
template and proberesp_ies and send the merged list to the FW
for offloading. It is still FW responsibility to filter out
irrelevant IEs when sending probe response, based on the actual
contents of the probe request.
Also in case association response termplate is not provided,

Currently the privacy flag calculation in change_beacon
checks for RSN IE inside proberesp_ies, but normally it
is not found there. It works today because of code inside
the function wil_fix_bcon, but wil_fix_bcon is not directly
related to change_beacon, and it may be changed or removed
in the future and break the calculation.
To fix this issue, change the privacy flag calculation
to check RSN IE inside the beacon itself. The new check is more
reliable and will not be sensitive to changes in wil_fix_bcon.

Enable support for periodic peer stats update when peer stats
service is enabled. The host to update the peer stats received
from the firmware periodically, since firmware will reset this to zero
after sometime (due to memory constraints)
While enabling periodic peer / vdev stats cleanup the existing
list in debugfs if max limit is reached, so that the new stats is
updated.
Ideally speaking based on 'Michal Kazior's' suggestion
we need to completely move to periodic update of all the stats making
the 'ping - pong' method obselete. This requires a bit of re-work and
some testing as well, also confirmation regarding backward comptability
for various firmware and chipsets. Hence allow periodic update only
for peer_stats.

Lawrence reported that git clone could make system crash on a
Qualcomm ARM soc based device (DragonBoard, 1G memory without
swap) running 64bit Debian.
It's turned out the crash is related with rx skb allocation
failure. git could consume more than 600MB anonymous memory.
And system is in extremely memory shortage case.
But driver didn't handle the rx allocation failure case. This patch
doesn't submit skb to upper layer if rx skb allocation fails.
Instead, it reuse the old skb for rx DMA again. It's more like
drop the packets if system is in memory shortage case.
With this change, git clone is OOMed instead of system crash.

This patch is derived from
commit 6301566e0b ("ath9k: export HW random number generator"),
We evaluated the entropy of the ADC data on QCA9531, QCA9561, QCA955x,
and AR9340, and it has sufficient quality random data (at least 10 bits
and up to 22 bits of min-entropy for a 32-bit value). We conservatively
assume the min-entropy is 10 bits out of 32 bits. Thus, ATH9K_RNG_BUF_SIZE
is set to 320 (u32) i.e., 1.25 kilobytes of data is inserted to fill up
the pool as soon as the entropy counter becomes 896/4096 (set by random.c).
Since ADC was not designed to be a dedicated HW RNG, we do not want to bind
it to /dev/hwrng framework directly. This patch feeds the entropy directly
from the WiFi driver to the input pool. The ADC register output is only
used as a seed for the Linux entropy pool. No conditioning is needed,
since all the conditioning is performed by the pool itself.

The three eeprom implementations had quite some duplicate code when it
came to endianness swapping.
Additionally there was a bug in eeprom_4k and eeprom_9287 which
prevented the endianness swapping from working correctly, because the
swapping code was guarded within an "if (!ath9k_hw_use_flash(ah))". In
eeprom_def this check did not exist, so it seems that eeprom_def was the
only implementation where endianness swapping worked.
This patch takes the duplicate code and moves it from eeprom_* to
eeprom.c. The new code is derived from eeprom_def, while taking into
account the specifics from the other implementations.

QCA988X firmware starting from 10.2.4.70.12-2 has capability to support
Mesh Control Field Present bit in QoS field in native Wi-Fi mode.
Hence apply Mesh subtype according to the WMI service map.
Firmware will allows unicast, broadcast, multicast, and WDS frame
(FromDS = 1 and ToDS = 1) to be received via the interface, once Mesh
subtype is used.
The firmware and this patch together make native Wi-Fi mode comply to
IEEE802.11s Mesh frame in open mode, but the firmware doesn't yet
support secured Mesh mode.

Of a word in struct htt_data_tx_desc htt version >= 3.4 firmware uses
LSB 16-bit for frequency configuration which is used for offchannel tx
and MSB 16-bit is for peerid. But other firmwares using version 2.X
(10.1, 10.2.2, 10.2.4 and 10.4) are using 32-bit for peerid in htt tx
desc. So far no issue is found with the existing code setting peerid and
freq for HTT version 2.X, this could be mainly because of 0 as frequecy
(home channel) is being always passed with those firmwares. There may be
issues when non-zero freq is passed with firmware using < 3.4 htt version.
To be safe use target_version_major and target_version_minor along with
htt-op-version before configuring peer id and freq in htt tx desc. This
patch extends ath10k_mac_tx_frm_has_freq() to check for htt_op_version_tlv
and uses the helper while setting peerid in htt_tx_desc.

For the messages from host to target, shadow copy of CE descriptors
are maintained in source ring. Before writing actual CE descriptor,
first shadow copy is filled and then it is copied to CE address space.

The physical address necessary to unmap DMA ('bufferp') is stored
in ath10k_skb_cb as 'paddr'. ath10k doesn't rely on the meta/transfer_id
when handling send completion (htc ep id is stored in sk_buff control
buffer). So the unused output arguments {bufferp, nbytesp and transfer_idp}
are removed from CE send completion. This change is needed before removing
the shadow copy of copy engine (CE) descriptors in follow up patch.

Currently to avoid uncached memory access while filling up copy engine
descriptors, shadow descriptors are used. This can be optimized further
by removing shadow descriptors. To achieve that first shadow ring
dependency in ce_send is removed by creating local copy of the

European Union has made it mandatory that all devices working in 2.4 GHz
has to adhere to the ETSI specification (ETSI EN 300 328 V1.9.1)
beginnig this year. The standard basically speaks about interferences
in 2.4Ghz band.
For example, when 802.11 device detects interference, TX must be stopped
as long as interference is present.
Adaptive CCA is a feature, when enabled the device learns from the
environment and configures CCA levels adaptively. This will improve
detecting interferences and the device can stop trasmissions till the
interference is present eventually leading to good performances in
varying interference conditions.
The patch includes code for enabling adaptive CCA for 10.2.4 firmware on
QCA988X.

wcn36xx implements a ring buffer for transmitted frames for each
(high and low priority) DMA channel. The ring buffers are lockless:
new frames are inserted at the head of the queue, while finished
packets are reaped from the tail.
Unfortunately, the list manipulations are missing any kind of barriers
so are susceptible to various races: for example, a TX completion
handler might read an updated desc->ctrl before the head has actually
advanced, and then null out the ctl->skb pointer while it is still
being used in the TX path.
Simplify things here by adding a spin lock when traversing the ring.
This change increased stability for me without adding any noticeable
overhead on my platform (xperia z).

Some of the ath9k_phyerr enums were wrong from the
beginning (and even before). Most of the time the
codes were used for counters to be displayed over
debugfs, which made this a non-functional issue.
Some (e.g. ATH9K_PHYERR_FALSE_RADAR_EXT) are used
for radar detection and require the correct code
to work as intended.
This patch includes:
a) fixes
ATH9K_PHYERR_FALSE_RADAR_EXT: 24 => 36
ATH9K_PHYERR_CCK_LENGTH_ILLEGAL: 32 => 28
ATH9K_PHYERR_CCK_POWER_DROP: 33 => 29
ATH9K_PHYERR_HT_CRC_ERROR: 34 => 32
ATH9K_PHYERR_HT_LENGTH_ILLEGAL: 35 => 33
ATH9K_PHYERR_HT_RATE_ILLEGAL: 36 => 34
b) extensions
ATH9K_PHYERR_CCK_BLOCKER = 24
ATH9K_PHYERR_HT_ZLF = 35
ATH9K_PHYERR_GREEN_FIELD = 37
Aside from the correction and completion made in
the enum, the patch also extends the display of
the related counters in the debugfs.

This patch disables PCI PS for QCA988X and QCA99X0, Since PCI PS is
validated for QCA6174, let it be enabled only for QCA6174. It would be
better to execute PCI PS related functions only for the supported devices.
PCI time out issue is observed with QCA99X0 on x86 platform, We will
disable PCI PS for QCA988X and QCA99X0 until PCI PS is properly implemented.
Taking and releasing ps_lock is causing higher CPU consumption. Michal Kazior
suggested ps_lock overhead to be reworked so that ath10k_pci_wake/sleep
functions are called less often, i.e. move the powersave logic up (only during

Currently target to host (T2H) HTT messages are received at copy engine 1.
These messages are processed by HTC layer in both host and target.
To avoid HTC level processing overhead in both host and target,
the unused copy engine 5 is being used for receiving HTT T2H messages.
This will speedup the receive data processing as well as htt tx completion.
Hence host and target copy engine configuration tables are updated
to enable CE5 pipe. The in-direction HTT mapping is now pointing to CE5
for all HTT T2H.
Moreover HTT send completion messages are polled from HTC handler
as CE 4 is not interrupt-driven. For faster tx completion, CE4 polling
needs to be done whenever CE pipe which transports HTT Rx (target->host)
is processed. This avoids overhead of polling HTT messages from HTC
layer. Servicing CE 4 faster is helping to solve "failed to transmit
packet, dropping: -105".

QCA6174 needs different board files based on board type. To make it easier to
distribute multiple board files and automatically choose correct board file
create a simple TLV file format following the same principles as with FW IEs.
The file is named board-2.bin and contain multiple board files. Each board file
then can have multiple names.
ath10k searches for file board-N.bin (where N is the interface version number
for the board file, just like we for firmware files) in /lib/firmware/*, for
example for qca99x0 it will try to find it here:
/lib/firmware/ath10k/QCA99X0/hw2.0/board-2.bin
If ath10k doesn't find board-2.bin then it will fallback to the old board.bin file.
This patch adds a simple name scheme using pci device id which for now will be
used by qca6174:
bus=%s,vendor=%04x,device=%04x,subsystem-vendor=%04x,subsystem-device=%04x
This removes the old method of having subsystem ids in ar->spec_board_id and
using that in the board file name.

Add the option to configure multiple 'scan plans' for scheduled scan.
Each 'scan plan' defines the number of scan cycles and the interval
between scans. The scan plans are executed in the order they were
configured. The last scan plan will always run infinitely and thus
defines only the interval between scans.
The maximum number of scan plans supported by the device and the
maximum number of iterations in a single scan plan are advertised
to userspace so it can configure the scan plans appropriately.
When scheduled scan results are received there is no way to know which
scan plan is being currently executed, so there is no way to know when
the next scan iteration will start. This is not a problem, however.
The scan start timestamp is only used for flushing old scan results,
and there is no difference between flushing all results received until
the end of the previous iteration or the start of the current one,
since no results will be received in between.

The DFS pattern detector ought to reset the
detector lines when a pulse is added with
lower time stamp than the previous (which
indicates a TSF restart).
This did not work so far and is fixed with
this patch.
The modification does not change detection
performance within the driver, since it

After processing received packets from copy engine, host will allocate
new buffer and queue them back to copy engine ring for further
packet reception. On post rx processing path, skb allocation and
dma mapping are unnecessarily handled within ce_lock. This is affecting
peak throughput and also causing more CPU consumption. Optimize this
by acquiring ce_lock only when accessing copy engine ring and moving
skb allocation out of ce_lock.
In AP148 platform with QCA99x0 in conducted environment, UDP uplink peak
throughput is improved from ~1320 Mbps to ~1450 Mbps and TCP uplink peak
throughput is increased from ~1240 Mbps (70% host CPU load) to ~1300 Mbps
(71% CPU load). Similarly ~40Mbps improvement is observed in downlink

when all it needs is a boolean pointer.
It would be better to update this API to make it accept 'bool *'

Over that bool takes just a byte.
That required updates to all user sites as well, in the same commit

PRI value is used as divider when DFS detector analyzes candidate
radar pulses.
If PRI deviation is big from its origin PRI, DFS detector could miss
valid radar reports since HW often misses detecting radar pulses and
causes long interval value of pulses.
For instance from practical results, if runtime PRI is calculated as
1431 for fixed PRI value of 1428 and delta timestamp logs 15719,
the modular remainder will be 1409 and the delta between the remainder
and runtime PRI is 22 that is bigger than PRI tolerance which is 16.
As a result this radar report will be ignored even though it's valid.
By using spec defined PRI for fixed PRI, we can correct this error.

Current kernel support only one fw name with theoretically only one

compatibility problem which was decided to solve by firmware name and
location:
- new firmware is located now in
firmware/ath9k_htc/htc_[9271|7010]-1.4.0.fw
- old version 1.3 should be on old place, so old kernel have no issues
with it.
- new kernels including this patch should be able to try different
supported (min..max) fw version.
- new kernel should be able to support old fw location too. At least for
now.
At same time this patch will add new module option which should allow user
to play with development fw version without replacing stable one. If user
will set “ath9k_htc use_dev_fw=1” module will try to find

Add support for mesh to ath10k. We simply use an AP virtual interface
in the firmware in order to enable beaconing without TSF adoption, and
use the raw (802.11) transmit mode.
Due to firmware limitations, the firmware must operate in raw
(non-native 802.11) mode. As this is configured at firmware init time,
a new "rawmode" modparam is added, and mesh interfaces are available
only if rawmode=true. The firmware must advertise support for rawmode;
tested successfully with firmware 10.2.4.70.6-2.
When the module is loaded with (newly implemented) modparam rawmode=1, it
will enable operating an open mesh STA via something like the following:
ip link set wlan0 down
iw dev wlan0 set type mp
ip link set wlan0 up
iw dev wlan0 set freq 5745 80 5775

During long hours of stress testing like AP interface up/down along
with continuous ping flood from a station doing connect/disconnect,
it is observed that the system is not able to allocate DMA consistent
memory of size > 512KB chunks as requested by firmware in WMI_SERVICE_EVENTID.
With the system memory getting fragmented during the run based on the
size of the memory requested, the failure to return physically continguous
memory of high order can happen. Once the system gets to this situation,
bringing up the wifi interface will fail and a system reboot may be needed
to make it work again. This problem is obseved with QCA99X0.
To fix this issue, allocate the DMA memory requested by firmware during
device probe time and keep it during the life time of the device. WMI service
ready event handler is changed to allocate the memory chunks if it is
not already allocated or if the memory allocated for the previous ready
event is not same as the current requested ones. After this patch the
memory usage when wifi is inactive will be inceased by few 100KB to
3MB based on the target type.

MU-MIMO Rx involves different interpretation of
the VHT-SIG-A compared to SU-MIMO.
The incorrect interpretation led ath10k to report
VHT MCS values greater than 9 which subsequently
prompted mac80211 to drop such frames. This
effectively broke Rx with MU-MIMO in many cases
and manifested with a kernel warning in the log
which looked like this:

This adds additional 0x0041 PCI Device ID
definition to ath10k for QCA6164 which is a 1
spatial stream sibling of the QCA6174 (which is 2
spatial stream chip).
The QCA6164 needs a dedicated board.bin file which
is different than the one used for QCA6174. If the
board.bin is wrong the device will crash early
while trying to boot firmware. The register dump
will look like this:

To enable/configure spectral scan parameters in 10.4 firmware, existing
wmi spectral related functions can be reused. Link those functions in
10.4 wmi ops table.
In addition, adjust bin size (only when size is 68 bytes) before reporting
bin samples to user space. The background for this adjustment is that
qca99x0 reports bin size as 68 bytes (64 bytes + 4 bytes) in report
mode 2. First 64 bytes carries in-band tones (-32 to +31) and last 4 byte
carries band edge detection data (+32) mainly used in radar detection
purpose. Additional last 4 bytes are stripped to make bin size valid one.
This bin size adjustment will happen only for qca99x0, all other chipsets
will report proper bin sizes (64/128) without extra 4 bytes being added
at the end. The changes are validated in qca99x0 using 10.4 firmware.

Existing phyerr event handlers directly uses phyerr header format
(ie, struct wmi_phyerr and struct wmi_phyerr_event) in the code
exactly on how firmware packs it. This is the problem in 10.4 fw
specific phyerr event handling where it uses different phyerror
header format. Before adding 10.4 specific handler, little bit of
refactor is done in existing phyerr handlers.
Two new abstracted structures (struct wmi_phyerr_ev_hdr_arg and
struct wmi_phyerr_ev_arg) are introduced to remove dependency of using
firmware specific header format in the code. So that firmware specific
phyerror handlers can populate values to abstracted structures and
the following code can use abstracted struct for further operation.
.pull_phyerr_hdr is added newly to pull common phyerr header info
like tsf, buf_len, number of phyerr packed. Existing .pull_phyerr
handler is changed and called to parse every sub phyerrs in the event.
Validated these refactoring on qca988x hw2.0 using fw 10.2.4 version.

There are three WMI_CHAN_INFO events reported per channel
in QCA99X0 firmware. First one is a notification at the begining
of the channel dwell time with cmd_flag as CHAN_INFO_START(cmd_flag = 0),
second one is a notification at the end of the dwell time with cmd_flag
CHAN_INFO_PRE_COMPLETE (cmd_flag = 2) and the third is the indication
with CHAN_INFO_COMPLETE (cmd_flag = 1) which is the last indication for
the channel. Since there is a new state before the completion, the handler
is to fixed so that the counts are deducted from the ones reported with

Vif's vdev_id is used as queue number. However due
to the tx pausing design in ath10k it was possible
for a new interface to be created with its tx
queue stopped (via ieee80211_stop_queues). This
could in turn leave the interface inoperable until
ath10k_mac_tx_unlock() was called.
This problem only affected multi-vif scenarios when
new interfaces were created some time later after
other interfaces have been running for some time
and had Tx queue full at some point prior.
Possible manifestation of the bug was
authentication timeout for a client vif.

If peer creation failed during offchannel Tx the
driver attempted to delete the peer nonetheless.
This caused the ar->num_peers counter to be
incorrectly decremented. This subsequently could
cause the counter to drop below 0 and also
eventually lead to firmware crash because host
would think there are less peer entries created in
firmware then there really were.

Even though there's a WMI enum for fragmentation
threshold no known firmware actually implements
it. Moreover it is not possible to rely frame
fragmentation to mac80211 because firmware clears
the "more fragments" bit in frame control making
it impossible for remote devices to reassemble
frames.
Hence implement a dummy callback just to say
fragmentation isn't supported. This effectively
prevents mac80211 from doing frame fragmentation
in software.
This fixes Tx becoming broken after setting
fragmentation threshold.

Allow network stack part of Rx processing to run on separate core,

If RXHASH feature is enabled, the driver sets rxhash of each skb to 1
to enable RPS. The core for processing the rx skb is determined by RPS
mechanism according to rx_cpus bit mask which is configured at user level.
For processing skbs on different core from the core which processes

Initial QCA99X0 support has a known issue with TCP Tx throughput.
All other path such as UDP Tx/Rx and TCP Rx meet their expectation
(> 900Mbps), but TCP Tx marked as low as 5Mbps when single pair is
used on iperf.
The root cause is turned out because TSO flag is not initialized
properly so that firmware configures TSO in wrong way.
TSO flags in msdu extension descriptor is required to be reset
to indicate firmware there is no TSO is enabled, otherwise it
could act as TSO is enabled which causes huge throughput drop.
In fact, it's enough by resetting TSO flags only to prevent the
unexpected behavior, but initializing whole msdu ext. descriptor
will help to clear uncertainty of firmware could bring on as it
constantly updated.

Host memory required for firmware is allocated while handling
wmi service ready event. Right now, wmi service ready is handled
in tasklet context and it calls dma_alloc_coherent() with atomic
flag (GFP_ATOMIC) to allocate memory in host needed for firmware.
The problem is, dma_alloc_coherent() with GFP_ATOMIC fails in
the platform (at least in AP platform) where it has less atomic
pool memory (< 2mb). QCA99X0 requires around 2 MB of host memory
for one card, having additional QCA99X0 card in the same platform
will require similarly amount of memory. So, it's not guaranteed that
all the platform will have enough atomic memory pool.
Fix this issue, by handling wmi service ready event in workqueue
context and calling dma_alloc_coherent() with GFP_KERNEL. mac80211 work
queue will not be ready at the time of handling wmi service ready.
So, it can't be used to handle wmi service ready. Also, register work
gets scheduled during insmod in existing ath10k_wq and waits for
wmi service ready to completed. Both workqueue can't be used for
this purpose. New auxiliary workqueue is added to handle wmi service
ready.

cryptmode:

encapsulation to the firmware. This is the default mode.
1: Use sofware crypto engine globally with raw mode TX/RX
encapsulation to the firmware.
Known limitation:
A-MSDU must be disabled for RAW Tx encap mode to perform well when

When using DFS channels on Ath10k, kernel log has repeated warning message
'failed to process fft: -22' typically under medium/heavy traffic.
This patch switches the warnings to driver debug (WMI events) mode only
thus reducing log file noise.
DFS and spectral scan share underlying HW mechanisms and enabling one
(DFS) enables the other (spectral scan) as far as event reporting from
firmware to driver is concerned. Spectral scan events take no part in
processing of DFS radar pulses which are delivered as distinct events,
so the fft (spectral event) warning is harmless and DFS interference
detection/protection still occurs.

HTT_H2T_MSG_TYPE_MGMT_TX msg in 10.4 firmware carries additional
4 byte in htt_mgmt_tx_desc where it tells to firmware that at what
rate mgmt frame has to go out in the air. It's an optional parameter,
setting this field to zero will force firmware to choose auto rate
and send the frame out.
Those 4 byte info is missed out in the current code and 10.4 firmware
ended up reading some junk in those 4 byte and sometime malfunctioning.
Fix it by adding 4 byte in struct htt_mgmt_tx_desc. Non 10.4 firmware
will not process those four byte. So, adding 4 byte at the end of
struct htt_mgmt_tx_desc will not create any impact on other chipset.

QCA99X0 chip has an extra 4 bytes in rx_msdu_start,
20 bytes in rx_msdu_end and 20 bytes in rx_ppdu_end structure
which are used in htt_rx_desc and HTT Rx ring offset setup.
This is necessary for correct Rx for QCA99X0 or Rx descriptors

Since QCA99X0 uses fragmentation descriptor differently from
other ones on tx path, we need to handle it separately.
QCA99X0 is using 48 bits for address and 16 bits for length
out of 2 dword and each values have to be programmed by frag
desc base addr + msdu id, so that hardware can retrieve
corresponding frag data.

It is observed that during cold reset pcie access right
after a write operation to SOC_GLOBAL_RESET_ADDRESS causes
Data Bus Error and system hard lockup. The reason
for bus error is that pcie needs some time to get
back to stable state for any transaction during cold reset. Add
delay of 20 msecs after write of SOC_GLOBAL_RESET_ADDRESS
to fix this issue. This patch is tested on QCA988X. This is
also tested on QCA99X0 which is WIP.

A long time ago, ath9k had issues during reset where the DMA engine
would stay active and could potentially corrupt memory.
To debug those issues, the driver would print warnings whenever they
occur.
Nowadays, these issues are gone and the primary cause of these messages
is if the MAC is stuck during reset or busy processing a long
transmission. This is fairly harmless, yet these messages continue to
worry users.
To reduce the number of bogus bug reports, turn these messages into
debug messages and count their occurence in the "reset" debugfs file.

FCC long pulse radar (type 5) requires pulses to be
checked for chirping. This patch implements chirp
detection based on the FFT data provided for long
pulses.
A chirp is detected when a set of criteria defined
by FCC pulse characteristics is met, including
* have at least 4 FFT samples
* max_bin index moves equidistantly between samples
* the gradient is within defined range
The chirp detection has been tested with reference

Pre qca99X0 chipsets follows the model where dynamically allocate
memory for frag desc on getting new skb for TX. But, this is not
going to be the case in qca99X0. It expects frag desc memory to be
allocated at boot time and let the driver to reuse allocated memory
after every TX completion. So there won't be any dynamic frag memory
memory allocation in qca99X0 during data transmission.
qca99X0 hardware doesn't need fragment desc address to be programmed
in msdu descriptor for every data transaction. It needs to know only
starting address of fragment descriptor at the time of the boot.
During data transmission, qca99X0 hardware can retrieve corresponding
frag addr by adding programmed frag desc base addr + msdu id.
Allocate continuous fragment descriptor memory (same size as number of
descriptor) at the time of target initialization and configure allocated
dma address to the target via HTT_H2T_MSG_TYPE_FRAG_DESC_BANK_CFG.
How this is allocated continuous memory is going to be used is not
covered in this patch. It just allocates memory and hand over to firmware.
If we don't do it at init time, qca99X0 will stall when firmware tries
to do TX.

Due to 512 client support in 10.4 firmware, size of tim ie is going
to be slightly higher than non 10.4 firmware. So, size of tim_bitmap
what is carried in swba event from 10.4 firmware is bit higher.
The only bottle neck to reuse existing swba handler
ath10k_wmi_event_host_swba() for 10.4 is that code designed to deal
with fixed size tim bitmap(ie, tim_info[].tim_bitmap in wmi_swba_ev_arg).
This patch removes such size limitation and makes it more suitable
to handle swba event which has different size tim bitmap.
All existing swba event parsing functions are changed to adapt this
change. Actual support to handle 10.4 swba event is added in next patch.
Only preparation is made in this patch.

In the PRI detector, after the current radar pulse
has been checked agains existing PRI sequences, it
is considered as part of a new potential sequence.
Previously, the condition to accept a new sequence
was to have at least the same number of pulses as
the longest matching sequence. This was wrong,
since it led to duplicates of PRI sequences.
This patch changes the acceptance criteria for new

As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.
This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.
The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the

switching became broken which I failed to notice
until now.
Function ath10k_mac_vif_chan() reports current

In practice there's no point in having a copy of
chanctx_conf.
Most of the time the channel pointer (and band
along with it) is accessed and this can't change
after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().
The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback
context which guarantees safe access to the
chanctx data.

In some cases some channel survey data was
reported incorrect.
Channel info events were expected to come in pairs
without and with COMPLETE flag set respectively
for each channel visit during scan.
The known deviation from this is rule for last
scan chan info and first (next) scan chan info
both have COMPLETE flag set. This was either
programmed with the intent of providing BSS cycle
count info or this is an artefact of firmware scan
state machine. Either way this is useless due to
short wraparound time, wraparound quirks and no
overflow notification.
Survey dumps now include only data gathered during
scan channel visits that can be computed
correctly.
This should improve hostapd ACS a little bit.

When QCA988X cycle counter HW register wraps
around it resets to 0x7fffffff instead of 0. All
other cycle counter related registers are divided
by 2 so they never wraparound themselves. QCA61X4
has a uniform CC and it wraparounds in a regular
fashion though.
Worst case wraparound time is approx 24 seconds
(2**31 / 88MHz). Since scan channel visit times
are max 5 seconds (offchannel case) it is
guaranteed there's been at most 1 wraparound and
it is possible to compute survey active time
value. It is, however, impossible to determine the
point at which Rx Clear Count has been divided by
two so it is not reported upon wraparound.
This fixes some occasional incorrect survey data
on QCA988X as some channels (depending on how/when
scan/offchannel requests were requested) would
have approx 24 sec active time which wasn't
actually the case.
This should improve hostapd ACS a little bit.

When we disconnect from the AP, drivers call cfg80211_disconnect().
This doesn't know whether the disconnection was initiated locally
or by the AP though, which can cause problems with the supplicant,
for example with WPS. This issue obviously doesn't show up with any
mac80211 based driver since mac80211 doesn't call this function.
Fix this by requiring drivers to indicate whether the disconnect is
locally generated or not. I've tried to update the drivers, but may
not have gotten the values correct, and some drivers may currently
not be able to report correct values. In case of doubt I left it at
false, which is the current behaviour.
For libertas, make adjustments as indicated by Dan Williams.

Some firmware revisions pad 4th hw address in
Native Wifi Rx decap. This is the case with 10.x
and it was assumed that this is true for all
firmware images.
However QCA988X with 999.999.0.636 and QCA61X4
with WLAN.RM.2.0-00088 don't have the padding.
Hence add a feature flag indicating that the
padding isn't present so firmware images can
advertise it appropriately. This way driver will
behave as it was before with old firmware blobs
and doesn't cause any regressions from user
perspective.
Effectively this patch enables QCA988X with
999.999.0.636 and QCA61X4 with WLAN.RM.2.0-00088
to set up client bridging provided user has an
updated firmware blob.

By using SOC_WAKE register it is possible to bring
down power consumption of QCA61X4 from 36mA to
16mA when associated and idle.
Currently the sleep threshold/grace period is at a
very conservative value of 60ms.
Contrary to QCA61X4 the QCA988X firmware doesn't
have Rx/beacon filtering available for client mode
and SWBA events are used for beaconing in AP/IBSS
so the SoC needs to be woken up at least every
~100ms in most cases. This means that QCA988X
is at a disadvantage and the power consumption
won't drop as much as for QCA61X4.
Due to putting irq-safe spinlocks on every MMIO
read/write it is expected this can cause a little
performance regression on some systems. I haven't
done any thorough measurements but some of my
tests don't show any extreme degradation.
The patch removes some explicit pci_wake calls
that were added in 320e14b8db51aa ("ath10k: fix
some pci wake/sleep issues"). This is safe because
all MMIO accesses are now wrapped and the device
is woken up automatically if necessary.

Four minor merge conflicts:
1) qca_spi.c renamed the local variable used for the SPI device
from spi_device to spi, meanwhile the spi_set_drvdata() call
got moved further up in the probe function.
2) Two changes were both adding new members to codel params
structure, and thus we had overlapping changes to the
initializer function.
3) 'net' was making a fix to sk_release_kernel() which is
completely removed in 'net-next'.
4) In net_namespace.c, the rtnl_net_fill() call for GET operations
had the command value fixed, meanwhile 'net-next' adjusted the
argument signature a bit.
This also matches example merge resolutions posted by Stephen

Spectral scan supported by ath10k has capability to monitor and report
through whole bands and channels, but current buffer size is too small
to save reported spectral scan data.
This results in dropping 5G channel reports at all when dual band card
is used, so that users are not able to analyze spectral environments.
Hence increase the buffer size to fix the problem.
A spectral data size is vary based on the number of bins, so the unit
buffer size, 1140, is chose to minimize relay buffer fragmentation.
The total buffer size is also chose in tradeoff with spectral scan
support vs. kernel memory consumption.
Since theoretical maximum buffer size, 9.5MB, can be consumed with
512 bins in dual bands, we target to cover up to 128 bins for all
channels in dual bands and due to the buffer size limitation,
spectral scan with bin number bigger than 128 needs to be run on
single band each.

Since we can identify the FFT frames on the report by checking the
consistency of their magnitude info, we can process all of them,
even when some of them are corrupted.
This patch introduces two functions to quickly verify the integrity
of the mag_info fields and some further tweaks to detect the frames
in the report and process them.
Note that in case of missing bytes we don't duplicate them, instead
we leave them as zeroes. This way we get less noise on the FFT plot.

Maximum magnitude index is a 5bit signed integer,
convert to an 8bit signed integer and then "shift" it so that it can be used
as an array index. Note that the current implementation adds +1 to the index
value (so it can't be used as an array index) and it's only valid for HT20
channels.
Note that the maximum magnitude index is not being used by
the userspace tools that parse FFT samples (they just use
maximum magnitude) so this doesn't break userspace compatibility.

Major changes in ath10k:
* enable channel 144 on 5 GHz
* enable Adaptive Noise Immunity (ANI) by default
* add Wake on Wireless LAN (WOW) patterns support
* add basic Tunneled Direct Link Setup (TDLS) support
* add multi-channel support for QCA6174
* enable IBSS RSN support
* enable Bluetooth Coexistance whenever firmware supports it
* add more versatile way to set bitrates used by the firmware
Until now only a single fixed tx rate or nss was
allowed to be set.
The patch attempts to improve this by allowing
most bitrate masks. The limitation is VHT MCS
rates cannot be expressed separately using
existing firmware interfaces and only the
following VHT MCS ranges are supported: none, 0-7,
0-8, and 0-9.
This keeps the old behaviour when requesting
single tx rate or single nss. The new bitrate mask
logic is only applied to other cases that would
return -EINVAL until now.
Depending on firmware revisions some combinations
may crash firmware so use with care, please.
This depends on "ath10k: don't use reassoc flag".
Without it key cache would effectively be
invalidated upon bitrate change leading to
communication being no longer possible.
These work:
iw wlan0 set bitrates legacy-5 6 12 ht-mcs-5 1 2 3
iw wlan0 set bitrates legacy-5 ht-mcs-5 7 8 9

These won't work:

Some devices differ slightly and require different
board files. If wrong board data is used they
crash or behave incorrectly.
These devices can be differentiated by looking at
PCI subsystem device id. That is the case for
qca61x4 devices at least.
The board specific filename is constructed as:
board-<bus>-<id>.bin
For PCI in particular it is:
board-pci-<vendor>:<dev>:<subsys_vendor>:<subsys_dev>.bin
These files are looked in device/hw specific
directories. Hence for Killer 1525 (qca6174 hw2.1)
ath10k will request:
/lib/firmware/ath10k/QCA6174/hw2.1/board-pci-168c:003e:1a56:1525.bin
To not break any existing setups (e.g. in case
some devices in the wild already have subsys ids)
if a board specific file isn't found a generic one
is used which is the one which would be used until
now. This guarantees that after upgrading a driver
device will not suddenly stop working due to
now-missing specific board file. If this is the
case a "fallback" string is appended to the info
string when driver boots.
Keep in mind this is distinct from cal-pci-*.bin
files which contain full calibration data and MAC
address. Cal data is aimed at systems where
calibration data is stored out of band, e.g. on
nand flash instead of device EEPROM - an approach
taken by some AP/router vendors.
Board files are more of a template and needs some
bits to be filled in by the OTP program using
device EEPROM contents.
One could argue to map subsystem ids to some board
design codename strings instead of using raw ids
when building the board filename. Using a mapping
however would make it a lot more cumbersome and
time consuming (due to how patches propagate over
various kernel trees) to add support for some new
device board designs. Adding a board file is a lot
quicker and doesn't require recompilation.

WLAN survey data provides several informative values on each channels
such as noise, active time, transmit time, and etc.
Regarding the channel activity time data, it is reported from firmware
in different form which is number of cycles instead of time itself.
Hence host driver converts it to time unit by dividing it by clock rate
that is used at baseband MAC.
Using difference clock rate from that actual HW is using will result in
inaccurate survey data. For instance, channel active time can be reported
with bigger than 150ms even though we set Dwell time to 150ms.
Therefore set the clock rate to 88000 (88 MHz) which is ath10k baseband
MAC is using.

With latest additions to the driver it seems
viable to enable support for IBSS-RSN.
It seems to work on QCA988X and 999.999.0.636 but
is a bit slow to exchange RSN keys for some
reason. This may be a firmware quirk or ath10k is
missing something. Nevertheless it makes sense to
finally enable IBSS-RSN in ath10k even if somewhat
handicapped.
QCA6174 firmware doesn't seem to be able to Tx
EAPOL frames at all now (they get stuck in hw
queues for some reason) so it never gets to set
the keys in driver. It's fairly safe to assume that
once this is fixed IBSS-RSN will work with QCA6174

Also there seems to be some kind of issue with

Frames are logged via tracing in two slices:
header and payload, separately. This is done for
performance reasons when one wants to, e.g.
analyse metadata only of frames only.
If for some reason device delivered a frame buffer
which was sized below what 802.11 header implied
tracing logic would blow doing an invalid memory
accesses.
I've hit this problem when running IBSS on QCA988X
with 999.999.0.636 and tracing at the same time.

Japan's W53 band requires 50% data traffic during its DFS test,
but WLAN baseband used by ath9k and ath10k is not able to achieve
current threshold rate, 50%, under the data traffic rate.
In other words, HW occasionally fails detecting radar pulses,
so that SW cannot get enough radar reports to achieve the rate.

Separate Japan's DFS pattern from FCC to control PPB threshold.
Currently all the radar detectors use the same threshold rate at
50%, but it's not able to achieve if data traffic rate is higher
than 40% because WLAN baseband used by ath9k and ath10k often fails
detecting radar pulses, so that SW cannot get enough radar reports
to achieve the rate.
Since Japan's W53 band requires 50% data traffic during its DFS
test we need to apply different threshold rate than others on it.
Hence define its own pattern to give flexibility to threshold rate.

This improves chances of getting onto a foreign
channel and thus makes P2P a bit more reliable.
Without scan burst it was possible for firmware to
not switch to foreign channel resulting in "failed
to switch to channel for roc scan" warning. This
would also effectively fail some offchan tx
requests and lead to P2P find/connect taking
longer. This could be observed when other vifs

Add support for new FCC DFS rules released on August 14, 2014.
FCC has added a new radar type named Radar Type 1 and original
Radar Type 1 is renamed to Radar Type 0 in consequence.
During the certificate test, Type 1 PRI values are randomly selected
within the range of 518 and 3066 and we divide it to 3 groups based on
practical test result data collected for more than a year.
For about Radar type ID, it does nothing to functionalities.
In other words, even if we re-order the IDs, DFS detection will
work as well, but we give the ID with matching to FCC doc.
By adding this support, the drivers using this DFS function are
able to support both of old and new FCC DFS rules simultaneously
without any other changes.

The number of 3 vdevs wasn't enough to handle the

wpa_supplicant may need up to 4 vifs to have 2
vifs actually connected, i.e. p2pdev + client + 2x
p2p (either p2p client or p2p go).
This fixes worst case warning:
Free vdev map is empty, no more interfaces allowed.
This keeps the ability to associate 32 stations in

This will expose in /sys whether the ifname of a device is set by
userspace or generated by the kernel. The latter kind (wlanX, etc)
is not deterministic, so userspace needs to rename these devices
to names that are guaranteed to stay the same between reboots. The
former, however should never be renamed, so userspace needs to be
able to reliably tell the difference.

patch:
c23e31cf7b mac80211: initialize rate control earlier for tdls station
Firmware 10.2.4.48-3 now supports management frames over HTT feature and has
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX. But as 10.2.4 branch has conflicting HTT ids
patch "ath10k: add ATH10K_FW_IE_HTT_OP_VERSION" is needed to fix the issue.
Older ath10k versions don't have support that support and to maintain backwards
compatibility we need bump up the FW API to 5 not break older versions.
Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
Target to host HTT messages are conflicting between 10.x and other
firmware revisions. By maintaining separate HTT T2H tables for each
firmware revisions (main, 10x and tlv) similar to WMI abstraction,
solves the conflicts. Add ATH10K_FW_IE_HTT_OP_VERSION so that the firmware can
advertise the HTT interface to ath10k.
This fix is needed to get management frames over HTT (ie.
ATH10K_FW_FEATURE_HAS_WMI_MGMT_TX disabled) working with 10.2.4.48-2 firmware.
Otherwise there will be unknown htt events and nothing works:
[30087.438343] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30087.448691] ath10k_pci 0000:02:00.0: htt event (19) not handled
[30149.032974] ath10k_pci 0000:02:00.0: htt event (19) not handled
If the firmware does not have ATH10K_FW_IE_HTT_OP_VERSION use the main HTT
interface. That way old firmware images will still work.

Since thermal daemon is unaware of the device state, it might
try to adjust the throttle state when the device is powered down.
So the driver caches the value and will configure it while
powering up the target. The cached value will be programed later
once the device is brought up. In such case, returning error
status is confusing and misleading the user application. Hence
moving the driver state check before sending wmi command to target.

For the networking code and for hardware network accelerators,
it is better to have IP header 4*n aligned. On the other side,
DMA on Rx path require buffer to be aligned on 4*n as well.
Having 14 bytes of Ethernet header, these 2 alignment
requests are in contradiction.
To solve this, order hardware offload block to not remove
SNAP header. This adds extra 6 bytes between addresses and
ethertype, making it 20 bytes total. This way, both buffer and
IP header are 4*n aligned. Remaining is only to remove SNAP
by shifting addresses 6 bytes. This involves data copying, so
this feature should be disabled unless required by the platform.

introduced to control this feature. Feature is completely disabled
when parameter is false.

Some firmware revisions (tested with qca6174
rm2.0-00088) deliver unsolicited unknown (kind of
garbled) HTC ep0 event to host in some cases.
This issue was mainly observed with both qca988x
and qca6174 being installed on a single host
system. During driver probing if qca6174 booting
sequences were somehow deferred (e.g. by qca988x
implicitly making some resources busy presumably)
the unsolicited event would came around 1s after
ATH10K_HTC_MSG_READY_ID was delivered to host for
qca6174.
The unsolicited event would confuse driver and
cause HTT initialization (and subsequently
driver probing) to fail.
Make the ep0 event processing more robust. The
event will still be caught but instead will
only generate a warning now.

ath10k association). Some ath9k APs would

* sniffing own tx frames via radiotap because,
e.g. wireshark was seeing QoS bit set but
since QoS Control was stripped in ath10k it
would parse beginning of LLC/SNAP

To prepare for reset ath5k should finish all asynchronous tasks. At
first, it disables the interrupt generation, then it waits for the
interrupt handler and tasklets completion, and then proceeds to the HW
configuration update. But it does not consider that the interrupt
handler or tasklet re-enables the interrupt generation. And we fall in a
situation when ath5k assumes that interrupts are disabled, but it is
not.
This can lead to different consequences, such as reception of the frame,
when we do not expect it. Under certain circumstances, this can lead to
the following warning:

Fix this issue by adding a new status flag, which forbids to re-enable
the interrupt generation until the HW configuration is completed.
Note: previous patch, which reorders the Rx disable code helps to avoid
the above warning, but not fixes the root cause of unexpected frame
receiving.

ath5k updates the channel pointer and after that it stops the Rx logic
and apply channel to HW. In case of channel switch, such sequence
creates a small window when a frame, which is received on the old
channel is considered as a frame received on the new one.
The most notable consequence of this situation occurs during the switch
from 2 GHz band (CCK+OFDM) to the 5GHz band (OFDM-only). Frame received
with CCK rate, e.g. beacon received at the 1mbps, causes the following
warning:

The easiest way to reproduce this warning is to run scan with dualband
NIC in noisy environments, when the channel 11 runs multiple APs. In my
tests if the APs num >= 12, the warning appears in the first few
seconds of scanning.
In order to fix this, the Rx disable code moved to a higher level and
placed before the channel pointer update. This is also makes the code a
bit more symmetrical, since we disable and enable the Rx in the same
function.
In fact, at the pointer update time new frames should not appear,
because interrupt generation at this point should already be disabled.
The next patch should address this issue.

Promiscuous mode is enabled when wlan interface is added to
bridge. ath10k creates a monitor mode when promiscuous mode
is enabled. When monitor vdev is running along with other
vdev(s) there is a huge number of interrupts generated
especially in noisy condition. Fix this by not enabling
promiscuous(monitor) mode when already a vdev is running.
As disabling promiscuous mode may have issues with 4-address
bridging in STA mode, the change is done specific to non-sta/ibss
mode types. This does not change the support of virtual interface of
type monitor along with other vdevs of any type.
This could fix management frame drop in fw due to unavailable
buffers because in monitor mode device receives everything seen
on the air. In noisy condition, disabling monitor mode helps assoc
go through without any issue.

In order to get the BSS struct for the new PBSS networks, change the

argument with the valid network types, as "capa_mask" and "capa_val"
no longer work correctly (the search must be band-aware now.)

Boot loader reports MAC address and detects radio chip connected.

Sometimes while CPU have some load and ath5k doing the wireless
interface reset the whole WiSoC completely freezes. Set of tests shows
that using atomic delay function while we wait interface reset helps to
avoid such freezes.
The easiest way to reproduce this issue: create a station interface,
start continous scan with wpa_supplicant and load CPU by something. Or
just create multiple station interfaces and put them all in continous
scan.
This patch partially reverts the commit 1846ac3dbe ("ath5k: Use
usleep_range where possible"), which replaces initial udelay()
by usleep_range().
I do not know actual source of this issue, but all looks like that HW
freeze is caused by transaction on internal SoC bus, while wireless
block is in reset state.
Also I should note that I do not know how many chips are affected, but I
did not see this issue with chips, other than AR5312.

Ath10k driver sets wrong default key idx that results in
sending unicast frames with multicast key.
The reason for this behavior is that cached broadcast key
is installed for station MAC address on association. After
dot1x completes, unicast key is installed for station
MAC address. Default key idx is set to broadcast key id when
driver tries to send broadcast frame. This causes firmware
to use broadcast key id to transmit unicast frames to stations.
Used TX_USAGE flag to set default key for stations.
Added callback for setting unicast default idx which will be
invoked on every default key idx configuration.

Advanced interrupt moderation bypasses misc, and handles separately tx

Max burst duration timer which defines how long to postpone interrupt after
first event (receive event for rx and tx complete event for tx), and
interframe timeout which defines how to determine the end of the burst and
issue interrupt even if the first timer still pending.
Capabilities flags in wil_priv is set on initialization according to
HW. The rest of the code checks for advanced interrupt capability bit
in capabilities flags field.
Debugfs is split accordingly: "legacy" interrupt moderation remains
unchanged, new debugs files added for advanced interrupt moderation
support.
Module params are aligned to support advanced interrupt moderation
(tx & rx). When not available (for legacy interrupt moderation) will
use only rx configuration; Tx configuration will be ignored in this

Introduce BACK establishment procedures; decision logic is not implemented
yet; debugfs entry 'addba' used to manually trigger addba/delba for ringid 0.
debugfs usage:
to establish BACK with agg_wsize 16:
echo 16 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba
to delete BACK:
echo 0 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba
to change agg_wsize, one need to delete BACK and establish it anew
ADDBA flow for:
- originator
Tx side (initiator) sends WMI_VRING_BA_EN_CMDID providing
agg_wsize and timeout parameters.
Eventually, it gets event confirming BACK agreement - WMI_BA_STATUS_EVENTID
with negotiated parameters. On this event, update Tx vring data
(struct vring_tx_data) and display BACK parameters on debugfs
- recipient
Rx side (recipient) firmware informs driver about ADDBA with
WMI_RCP_ADDBA_REQ_EVENTID, driver process it in service work
queue wq_service. It adjusts parameters and sends response
with WMI_RCP_ADDBA_RESP_CMDID, and final confirmation provided
by firmware with WMI_ADDBA_RESP_SENT_EVENTID. In case of success,
driver updates Rx BACK reorder buffer.
policy for BACK parameters:
- aggregation size (agg_wsize * MPDUsize)) to not exceed 64Kbytes
DELBA flow for:
- originator
driver decides to terminate BACK, it sends WMI_VRING_BA_DIS_CMDID
and updates struct vring_tx_data associated with vring; ignore
WMI_DELBA_EVENTID.
- recipient
firmware informs driver with WMI_DELBA_EVENTID,
driver deletes correspondent reorder buffer
ADDBA request processing requires sending WMI command, therefore
it is processed in work queue context. Same work queue used as for
connect, it get renamed to wq_service

Due to some changes in power_up/reset sequences
sometimes when fw crashed ath10k would print the

is done using hw MAC quiet time setting. Period, duration and offset
from TBTT can be set up to quiet the MAC transmits for the required duty
cycle (% of quiet duration). The thermal device allows user to configure
duty cycle.
The quiet params are derived as follows.
period = max(25TU, beacon interval / number of bss)
duration = period * duty cycle / 100
Quiet mode can be disabled by setting the duty cycle to 0. The cooling

Pull driver core update from Greg KH:
"Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes,
just removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There
are some ath9k patches coming in through this tree that have been
acked by the wireless maintainers as they relied on the debugfs
changes.
Everything has been in linux-next for a while"

Introduce a new wmi interface controls noise floor (NF) calibration
period via debugfs as firmware has introduced it on v10.2.
It allows users to modify frequency of NF calibration in millisecond
and changes RSSI reporting frequency consequently.
Short calibration period will trigger more frequent NF calibration,
so that RSSI reported in receive frames is more realistic.
Till now calibration was done at 30 seconds.

Add mem_val debugfs file for dumping the firmware (target) memory and also for
writing to the memory. The firmware memory is accessed through one file which
uses position of the file as the firmware memory address. For example, with dd
use skip parameter for the address.
Beucase target memory width is 32 bits it's strongly recommended to use
blocksize divisable with 4 when using this interface. For example, when using
dd use bs=4 to set the block size to 4 and remember to divide both count and
skip values with four.
To read 4 kB chunk from address 0x400000:
dd if=mem_value bs=4 count=1024 skip=1048576 | xxd -g1
To write value 0x01020304 to address 0x400400:
echo 0x01020304 | xxd -r | dd of=mem_value bs=4 seek=1048832
To read 4 KB chunk of memory and then write back after edit:
dd if=mem_value of=tmp.bin bs=4 count=1024 skip=1048576

When static keys are used in shared WEP, when a

deauth, the auth frame is decrypted by the HW.

Currently, when a roc period expires, the offchannel
timer calls ieee80211_remain_on_channel_expired(), but
the roc state is cleared only when the queued work
to switch to the operating channel gets a chance to run.
This race is a problem because mac80211 can issue a
new roc request in this window. To avoid this, handle
roc completion in the offchannel timer itself.

In a GO/STA setup, when we switch to the STA context,
the channel context timer is scheduled with a period of
half the beacon interval. If a beacon is received in
this duration, the timer is adjusted to accommodate
TSF sync done by the HW.
But, if the actual channel switch is delayed for some
reason, we end up rearming the timer every time a new
beacon is received. Avoid this by doing the adjustment
only once.

When a pending roc or scan operation is cancelled,
the offchannel operation is cleared, but the offchannel
state in the main scheduler is not cleared. This causes
problems since an active GO will try to process a stale

(roc/scan) operation.

This patch "ath9k_htc_firmware: fix the offset of CCMP header

this is not working and we still need CCMP encryption of
transmitted management frames to be done in software.
So this patch allows the software encryption for transmitted
management frame to be done in software but remain the hardware
decryption for received management frame.
This patch is tested with the following hardwares:

disconnect 5 of them, leaving sta0 up
Start trying to bring up the other 5 one at a time. It will

While testing other things I've found that CE

null dereferences in BMI.
To prevent that make sure CE revoking clears the
nbytes value (which is used as a buffer completion
indication) and memset the entire CE ring data
shared between host and target when
(re)initializing.
Also make sure to check BMI xfer pointer and print

One of the problems with warm reset I've found is
that it must be guaranteed that copy engine

Instead of using sleeps and hoping the device is

firmware indication register.

Disconnect flow may be invoked either from upper layer request,

In case of firmware event, driver need to release resources for the station but

In case of upper layer request, WMI_DISCONNECT_STA_CMDID command need to
be issued for the firmware to perform disconnect on the MAC layer. Eventually,

mac80211 currently has a race which can be hit
with this sequence:
* Start a scan operation.
* TX BA is initiated by ieee80211_start_tx_ba_session().
* Driver sets up internal state and calls
ieee80211_start_tx_ba_cb_irqsafe().
* mac80211 adds a packet to sdata->skb_queue with
type IEEE80211_SDATA_QUEUE_AGG_START.
* ieee80211_iface_work() doesn't process the
packet because scan is in progress.
* ADDBA response timer expires and the sta/tid is
torn down.
* Driver receives BA stop notification and calls
ieee80211_stop_tx_ba_cb_irqsafe().
* This is also added to the queue by mac80211.
* Now, scan finishes.
At this point, the queued up packets might be processed
if some other operation schedules the sdata work. Since
the tids have been cleaned up already, warnings are hit.
If this doesn't happen, the packets are left in the queue
until the interface is torn down.
Since initiating a BA session when scan is in progress
leads to flaky connections, especially in MCC mode, we
can drop the TX BA request. This improves connectivity
with legacy clients in MCC mode.

The flush timeout in MCC mode is very small, since
we are constrained by the time slice for each
channel context, but since only the HW queues are
flushed when switching contexts, it is acceptable.
Since the SW queues are also emptied in the mac80211 flush()

is called in MCC mode. This allows the driver to

In MCC mode, the duration for a channel context
is half the beacon interval and having a large
flush timeout will adversely affect GO operation,
since the default value of 200ms will overshoot
the advertised NoA absence duration.
The scheduler initiates a channel context switch
only when the slot duration for the current
context expires, so there is no possibility of
having a fixed timeout for flush.
Since the channel_switch_time is added to the
absence duration when the GO sets up the NoA
attribute, this is the maximum time that we
have to flush the TX queues. The duration is very
small, but we don't have a choice in MCC mode.

When a HW reset is done, the interrupt tasklet is
disabled before ISRs are disabled in the HW. This
allows a small window where the HW can still generate
interrupts. Since the tasklet is disabled and not killed,
it is not scheduled but deferred for execution at a later
time.
This happens because ATH_OP_HW_RESET is not set when ath_reset()
is called. When the hw_reset_work workqueue is used, this
problem doesn't arise because ATH_OP_HW_RESET is set
and the ISR bails out.

In MCC mode, currently the decision to enable

This allows the driver to switch to the other

A frequent request have been to be able to provide calibration data from a

This patchset adds support for that and also makes it easier to add Device Tree
support later on.
The calibration data is found by using the id string provided by dev_name()
using this format:
cal-<bus>-<id>.bin
With PCI the id string contains bus, slot and func values. For example for a
PCI device in bus 2 slot 0, ath10k will try to retrieve a calibration data from
a file:
/lib/firmware/ath10k/cal-pci-0000:02:00.0.bin
The calibration data sequence is:
1. Check with request_firmware() if there's a calibration file
("cal-<bus>-<id>.bin") on the filesystem for this device. If yes, use that. If
not, goto 2
2. Check if otp.bin is able to successfully load the calibration data
from OTP. If yes, use that. If not, goto 3.
4. Print an error message that no calibration data found and stop driver

Based on GFP flag given to DMA coherent allocation, the behaviour of
dma_free_coherent is changed. This behavioural diffrence is noticeable
in ARM platform. If DMA memory is allocated with GFP_KERNEL, free
coherent can not be called inside spin lock. This is causing kernel
crash in ARM platforms. Fix this by changing GFP flag to atomic.
This is most likely a regression from commit 64badcb6d6 ("ath10k: workaround
fw beaconing bug").

Fabian Frederick tweaks some kernel-doc bits to avoid warnings.
Larry Finger corrects a possible unaligned access in the rtlwifi code.
Marek Puzyniak avoids a kernel panic in ath9k_hw_reset.
Sujith Manoharan goes for the hat trick -- he fixes a smatch warning
in the shared ath code, he fixes a crash in ath9k, and he corrects
a sequence number assignment problem in ath9k too.

Currently, ath9k uses a global counter for all
frames that need to be assigned a sequence number.
QoS-data frames are handled properly since they
have a per-tid counter. But, beacons and other
management frames use the same counter even if
multiple interfaces or contexts are present.
Fix this issue by making the counter per-interface
and using it when mac80211 sets IEEE80211_TX_CTL_ASSIGN_SEQ.

This results in unfairness for the inactive context.

there is a context mismatch, we can awaken all the

Some firmware revisions don't wait for beacon tx
completion before sending another SWBA event. This
could lead to hardware using old (freed) beacon
data in some cases, e.g. tx credit starvation
combined with missed TBTT. This is very very rare.
On non-IOMMU-enabled hosts this could be a
possible security issue because hw could beacon
some random data on the air. On IOMMU-enabled
hosts DMAR faults would occur in most cases and
target device would crash.
Since there are no beacon tx completions (implicit
nor explicit) propagated to host the only
workaround for this is to allocate a DMA-coherent
buffer for a lifetime of a vif and use it for all
beacon tx commands. Worst case for this approach
is some beacons may become corrupted, e.g. garbled
IEs or out-of-date TIM bitmap.
Keep the original beacon-related code as-is in
case future firmware revisions solve this problem
so that the old path can be easily re-enabled with
a fw_feature flag.

The NoA duration for a GO is half the beacon interval
and a concurrent context like a STA can be active only
for that duration, before switching back to the GO's
operating channel.
Currently, when multiple beacons are missed, the dwell
time for the STA context is extended to improve the
chances of receiving a beacon. But the NoA is not updated
and this will cause problems since the GO is offline
for a period that is longer than the advertised duration.
Fix this by ensuring that the NoA is updated first before
extending the time slot for the STA context. Also make
sure that non-periodic NoA is used for a one-time, longer
absence period.

Reason is the following: when removing Rx vring
(wil_netdev_ops.ndo_stop -> wil_stop -> wil_down -> __wil_down -> wil_rx_fini),
Rx interrupt occurs. It trigger Rx NAPI, calling wil_rx_handle() that reaps
(already cleaned) buffer, causing skb referring to garbage memory being set into reorder buffer.
Then, network stack trying to access this buffer and fails.
Prevent Rx NAPI from being scheduled if device going to stop. Bit wil_status_napi_en reflects
NAPI enablement state, check it when triggering Rx NAPI.
Testing shows that check for wil_status_napi_en sometimes gets negative, and new error message
get printed - in this case kernel oops would be observed. Original oops is no more reproducible.
This change requires also changes in the AP flows.
Properly enable/disable NAPI for the AP. Make sure Rx VRING is disabled
when resetting target.
For this, promote __wil_up() and __wil_down() to the module scope, and use it
in the relevant flows.

This reverts commit 09ebb81092.
ath9k_hw_set_sta_beacon_timers() configures AR_TIM_PERIOD with
the beacon interval. Before this commit, the sleepduration was
never greater than the beacon interval. But now, the behavior
has changed. For example, with an AP that uses a beacon interval of 100:
ath: phy9: next beacon 61128704
ath: phy9: beacon period 204800
ath: phy9: DTIM period 204800
If the sleepduration is calculated based on the listen time, then
the bmiss threshold should also be changed since the HW would
be in sleep state for a longer time, but that is not done currently.
To avoid configuring a higher beacon interval based on the sleepduration,
revert to the original behavior. Power consumption is not a
problem since PS is disabled in ath9k anyway.

Scanning is curently broken when two channel contexts
are active. For example in a P2P-GO/STA setup, the
offchannel timer allows HZ / 10 to elapse before initiating
a switch to the next scan channel from the current operating
channel, which in this case would be the P2P-GO context.
But, the channel context timer might decide to switch
to the STA context when an SWBA comes early and a beacon
is sent out. Since pending offchannel requests are processed
in EVENT_BEACON_PREPARE, this causes inconsistent scanning.
Fix this by making sure that a context switch happens
before processing the pending offchannel request. This
also makes sure that active channel contexts will always
have higher priority than offchannel operations and the
scan sequence looks like this:
p2p-go, sta, p2p-go, offchannel, p2p-go, sta, p2p-go, offchannel,.....
The oper-channel is p2p-go, so the STA context has to
switch to p2p-go again before switching offchannel.

When multiple channel contexts are active, an offchannel
request will not be handled immediately, but will be
queued to be handled later. But, currently, the channel definition
is not copied to the local offchannel state. This

The start time field in the NoA attribute needs to be
updated based on the TSF timer when an absence notification
is sent by the P2P GO. When two channel contexts are active,
continuous, cyclic NoA is announced by setting the count value to 255,
but the start time is updated only once, for one beacon and
the same value is sent in all subsequent beacons, even
though the timestamp keeps moving.
Fix this by removing the check for 'periodic_noa_duration'
and assign the interface's start_time/duration values directly
when there is more than one active context.

If a station interface is already assigned to a context
and is active and a second interface of type AP is added,
then beaconing on the new interface has to be begin only
after the BSS_CHANGED_BEACON_ENABLED flag is sent by mac80211
to the driver.
But, since we issue ATH_CHANCTX_EVENT_ENABLE_MULTICHANNEL as soon
as a new channel context is added, a switch occurs almost immediately
before BSS_CHANGED_BEACON_ENABLED is received. When a HW reset
is done for the new context, beacons are enabled for the
interface since "enable_beacon" in the BSS config maintained
in mac80211 is true - but the driver hasn't been notified yet.
This causes a panic, since the beacon interval is zero for this
interface and ath9k_cmn_beacon_config_ap() doesn't have a safety check.
Fix this panic by checking if the beacon params has been cached
for this context and use the "enable_beacon" flag maintained
locally in the driver. Also, recalculate the summary data
after the beacon params have been cached when BSS_CHANGED_BEACON_ENABLED
is received.

In channel context mode, when a new context is added,
mac80211 issues a bss_info_changed() notfication when
preparing the connection for the new interface/context.
But, this is done prior to the mgd_prepare_tx() call which
is where we switch to the new context. Since the current
context will be different when the earlier bss_info_changed()
is handled, the beacon information for the VIF is not
updated, but discarded since the rules for the current context
disallows it.
In the subsequent association process for the new context/vif,
this becomes a problem because the beacon parameters are invalid.
This causes problems with the TSF timer, causing large jumps.
To fix this, check if the beacon info is being updated for a
different context and if so, allow it without any checks since
we limit the max. interfaces to two anyway.

Recent changes done to start/restart sequences
broke hw recovery in some hw configurations. The
pci transport was stopped twice however due to a
workaround in the pci disabling code the
disable/enable for first msi interrupt was not
balanced. This ended up with irqs not being
properly re-enabled and the following print out
during recovery:
ath10k: failed to receive control response completion, polling..
ath10k: Service connect timeout: -110
ath10k: Could not init core: -110
Legacy interrupt mode was unaffected while msi
ranged mode would be partially crippled (it would
miss fw indication interrupts but otherwise it
worked fine).
This fixes completely broken fw recovery for a
single msi interrupt mode and fixes subsequent fw
crash reports for msi range interrupt mode.

According to RCU_INIT_POINTER()'s block comment 3.a, it can be used if
"3. The referenced data structure has already been exposed to readers either
at compile time or via rcu_assign_pointer() -and-
a. You have not made -any- reader-visible changes to this structure since
then".
This case fulfills the conditions above because between the rcu_dereference()
call (cvif = rcu_dereference(ar->beacon_iter);) and the rcu_assign_pointer()
call there is no update of the "cvif" variable.
Therefore, this patch makes the replacement.
The following Coccinelle semantic patch was used:
@@
identifier v;
@@
v = rcu_dereference(...);
... when != rcu_dereference(...);
when != v = ...;
when != (<+...v...+>)++;
when != \(memcpy\|memset\)(...);
(
- rcu_assign_pointer
+ RCU_INIT_POINTER
(..., v);
|
if(...) {
... when != v = ...;
- rcu_assign_pointer
+ RCU_INIT_POINTER
(..., v);
... when any
}
)
Because there are cases where between a “rcu_dereference()” call and a
“rcu_assign_pointer()” call might be updates of the value that interests us,
the Coccinelle semantic patch ignores them and replaces with
"RCU_INIT_POINTER()" only when the update is not happening.

The carl9170_op_ampdu_action() function is used only by the mac80211
framework.
Since the mac80211 already takes care of checks and properly serializing
calls to the driver's function there is no need for the driver to do the same
thing.

This patch ensures that the module parameter "use_chanctx" is
visible only when CONFIG_ATH9K_CHANNEL_CONTEXT is selected.
Also register the channel context callbacks with mac80211 only
when it is explicitly enabled and compile them out of the driver
when CONFIG_ATH9K_CHANNEL_CONTEXT is not selected.

Channel contexts are supported only for P2P right now,
so make sure that the 'normal' path remains unaffected
by using a config option. This will also reduce the size

Add the missing null termination after strncpy().
This isn't actually a buffer overflow in this case since we use
snprintf() appropriately to fill the buffer passed by the caller,
but in the interest of not turning this into a bug down the road,
go ahead and force termination here.

Based on a quick test with AR9271, TDLS seems to be working fine.
Tests were done with 2 Atheros AR9271 based devices with firmware
1.3 (sha1 8d49f928aa40ac53c729189bff1333cd373a7fb5), associated
with a WAP54G access point. TDLS worked fine both in WPA2 mode and
without encryption. Stations maintained ping flood traffic between
each other and towards the AP without significant losses.
Not tested with AR7010.
TDLS was enabled in earlier patches the same way for other
Atheros drivers:
ath9k (fd6562344d),
and carl9170 (d1f3de71a5).

Recent crash dump patches introduced a regression.
If debugfs was disabled upon crash user could only
see the following:

In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation.
But, memory get allocated under spin_lock_bh(), this implies atomic context.
So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all
occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake),
and it should be this way or warning triggered in the memory allocation code.
Remove @gfp parameter as no actual choice exist, and use hard coded
GFP_ATOMIC for memory allocation.
