7e62a699aa iwlwifi: mvm: use dev_coredumpsg()
iwlmvm currently uses dev_coredumpm() to collect multiple
buffers, but this has the downside of pinning the module
until the coredump expires, if the data isn't read by any
userspace.

Avoid this by using the new dev_coredumpsg() method. We
still copy the data from the old way of generating it, but
neither hold on to vmalloc'ed data for a long time, nor do
we pin the module now.

7948b87308 iwlwifi: mvm: enable dynamic queue allocation mode
New firmwares support dynamic queue allocation (DQA), which enables
on-demand allocation of queues per RA/TID, instead of allocating them
statically per vif.  This allows an AP to send, for instance, BE
traffic to STA2 even if it also needs to send traffic to a sleeping
STA1, without being blocked by the sleeping station.

The implementation in the driver is now ready, so we can enable this
feature by default when running firmwares that support it.

8236f7db27 iwlwifi: mvm: assign cab queue to the correct station
Currently when configuring the cab queue the scheduler is configured
without station id - which results in station id 0.
In DQA mode this causes firmware to assert later on when the actual
station 0 is added with an empty tfd_queue_mask.
Fix that by configuring the queue to the broadcast station.
This is a bit trickier since the queue should not be included in the
tfd_queue_mask of the ADD_STA since it is a multicast queue, and the
tfd_queue_mask is only unicast queue. As a result the queue should be
enabled only after the broadcast station is added.

its AID to be able to compute the TIM IE by itself.
In DQA, the firmware has all the information it needs to

AID.

65e254821c iwlwifi: mvm: use firmware station PM notification for AP_LINK_PS
When using RSS on 9000 series devices, we can't rely on processing the
received frames for station powersave handling, since they could be
processed on different CPUs and out of order.

In order to still manage the powersave of stations, the firmware sends
a notification on sleep->wake, wake->sleep and - for U-APSD - frames
received with PM while already sleeping (with the TID.)

With this, the driver can set AP_LINK_PS, which is required for real
parallel RX. In addition, this requires checking for PS-Poll frames
and calling ieee80211_sta_pspoll() appropriately.

ad5de73734 iwlwifi: mvm: fix dqa deferred frames marking
When a STA has deferred traffic to TX, an appropriate bit
is turned on in %deferred_tx_frames to indicate deferred
traffic. This marking is never turned off, resulting in
iterating over TIDs with no deferred traffic.

Although this didn't cause any failures/errors/bugs, there
is still no point of iterating over these TIDs when not
needed.

3a732c65de iwlwifi: mvm: wake the wait queue when the RX sync counter is zero
When we sync the RX queues the driver waits to receive echo
notification on all the RX queues.
The wait queue is set with timeout until all queues have received
the notification.
However, iwl_mvm_rx_queue_notif() never woke up the wait queue,
with the result of the counter value being checked only when the
timeout expired.
This may cause a latency of up to 1 second.

2b55f43f8e iwlwifi: mvm: Add mem debugfs entry
In order to access cached/paged memory, there are a couple of firmware
commands (one for UMAC and one for LMAC) that let the host access memory
and registers indirectly. Since this is done by the firmware on behalf
of the host, even if memory is paged out or cached, the host will
retrieve the memory as the firmware sees it (paged out memory will get
paged in).

Export this mechanism via a debugfs entry for both read and write
access.

WARNING: This mechanism has no protections at all. Invalid addresses may
crash or hang the firmware. Writing to arbitrary memory also comes with
no guarantees.

186cd49a4d iwlwifi: mvm: move AP-specific code to right function
There's no need for the common MAC context function to have an
if on AP mode, the values can be overridden in the AP-specific
function later. Clean that up by adding the full command as a
new parameter to the AP-specific function, and doing it there.

3ee0f0e23e iwlwifi: mvm: fix DQA AP mode station assumption
There was recently a Full AP mode feature added where hostap adds
the station at auth stage, and not assoc.
However, when running with legacy hostapd, we get the auth response
before station was added, and tx_skb_non_sta fails to allocate
a queue, resulting in a complete failure of association.
Take care of this situation as well.
Add a warning when no valid queue is returned at all and make mvm
drop the packet instead of passing it on.
Refactor the function a bit while at it.
