drm/i915 fixes for v5.6-rc7:
- Track active elements during dequeue
- Fix failure to handle all MCR ranges
- Revert unnecessary workaround
Signed-off-by: Dave Airlie <airlied@redhat.com>
From: Jani Nikula <jani.nikula@intel.com>
Link: https://patchwork.freedesktop.org/patch/msgid/877dzgepvu.fsf@intel.com
Commit '16f17eda8bad ("drm/amd/display: Send vblank and user
events at vsartup for DCN")' introduces a new way of pageflip
completion handling for DCN, and some trouble.
The current implementation introduces a race condition, which
can cause pageflip completion events to be sent out one vblank
too early, thereby confusing userspace and causing flicker:
prepare_flip_isr():
1. Pageflip programming takes the ddev->event_lock.
2. Sets acrtc->pflip_status == AMDGPU_FLIP_SUBMITTED
3. Releases ddev->event_lock.
--> Deadline for surface address regs double-buffering passes on
target pipe.
4. dc_commit_updates_for_stream() MMIO programs the new pageflip
into hw, but too late for current vblank.
=> pflip_status == AMDGPU_FLIP_SUBMITTED, but flip won't complete
in current vblank due to missing the double-buffering deadline
by a tiny bit.
5. VSTARTUP trigger point in vblank is reached, VSTARTUP irq fires,
dm_dcn_crtc_high_irq() gets called.
6. Detects pflip_status == AMDGPU_FLIP_SUBMITTED and assumes the
pageflip has been completed/will complete in this vblank and
sends out pageflip completion event to userspace and resets
pflip_status = AMDGPU_FLIP_NONE.
=> Flip completion event sent out one vblank too early.
This behaviour has been observed during my testing with measurement
hardware a couple of time.
The commit message says that the extra flip event code was added to
dm_dcn_crtc_high_irq() to prevent missing to send out pageflip events
in case the pflip irq doesn't fire, because the "DCH HUBP" component
is clock gated and doesn't fire pflip irqs in that state. Also that
this clock gating may happen if no planes are active. This suggests
that the problem addressed by that commit can't happen if planes
are active.
The proposed solution is therefore to only execute the extra pflip
completion code iff the count of active planes is zero and otherwise
leave pflip completion handling to the pflip irq handler, for a
more race-free experience.
Note that i don't know if this fixes the problem the original commit
tried to address, as i don't know what the test scenario was. It
does fix the observed too early pageflip events though and points
out the problem introduced.

There is the code in the read_symbol function in 'scripts/kallsyms.c':
if (is_ignored_symbol(name, type))
return NULL;
/* Ignore most absolute/undefined (?) symbols. */
if (strcmp(name, "_text") == 0)
_text = addr;
But the is_ignored_symbol function returns true for name="_text" and
type='A'. So the next condition is not executed and the _text variable
is always zero.
It makes the wrong kallsyms_relative_base symbol as a result of the code
(CONFIG_KALLSYMS_BASE_RELATIVE is defined):
if (base_relative) {
output_label("kallsyms_relative_base");
output_address(relative_base);
printf("\n");
}
Because the output_address function uses the _text variable.
So the kallsyms_lookup function and all related functions in the kernel
do not work properly. For example, the stack trace in oops:
Call Trace:

There is measurable performance impact in some synthetic tests due to
commit 6d390e4b5d (locks: fix a potential use-after-free problem when
wakeup a waiter). Fix the race condition instead by clearing the
fl_blocker pointer after the wake_up, using explicit acquire/release

This does mean that we can no longer use the clearing of fl_blocker as

This is just a cleanup addition to Jann's fix to properly update the
transaction ID for the slub slowpath in commit fd4d9c7d0c ("mm: slub:
add missing TID bump..").
The transaction ID is what protects us against any concurrent accesses,
but we should really also make sure to make the 'freelist' comparison
itself always use the same freelist value that we then used as the new
next free pointer.
Jann points out that if we do all of this carefully, we could skip the
transaction ID update for all the paths that only remove entries from
the lists, and only update the TID when adding entries (to avoid the ABA
issue with cmpxchg and list handling re-adding a previously seen value).
But this patch just does the "make sure to cmpxchg the same value we
used" rather than then try to be clever.

When kmem_cache_alloc_bulk() attempts to allocate N objects from a percpu
freelist of length M, and N > M > 0, it will first remove the M elements
from the percpu freelist, then call ___slab_alloc() to allocate the next
element and repopulate the percpu freelist. ___slab_alloc() can re-enable
IRQs via allocate_slab(), so the TID must be bumped before ___slab_alloc()
to properly commit the freelist head change.
Fix it by unconditionally bumping c->tid when entering the slowpath.

By default, tty_port_init() initializes those parameters to a multiple
of HZ. For instance in line 69 of tty_port.c:
port->close_delay = (50 * HZ) / 100;
https://github.com/torvalds/linux/blob/master/drivers/tty/tty_port.c#L69
With e.g. CONFIG_HZ = 250 (as this is the case for Ubuntu 18.04
linux-image-4.15.0-37-generic), the default setting for close_delay is
thus 125.
When ioctl(fd, TIOCGSERIAL, &s) is executed, the setting returned in
user space is '12' (125/10). When ioctl(fd, TIOCSSERIAL, &s) is then
executed with the same setting '12', the value is interpreted as '120'
which is different from the current setting and a EPERM error may be
raised by set_serial_info() if !CAP_SYS_ADMIN.

We have been receiving bug reports that ethernet connections over
RTL8153 based ethernet adapters stops working after a while with
errors like these showing up in dmesg when the ethernet stops working:
[12696.189484] r8152 6-1:1.0 enp10s0u1: Tx timeout
[12702.333456] r8152 6-1:1.0 enp10s0u1: Tx timeout
[12707.965422] r8152 6-1:1.0 enp10s0u1: Tx timeout
This has been reported on Dell WD15 docks, Belkin USB-C Express Dock 3.1
docks and with generic USB to ethernet dongles using the RTL8153
chipsets. Some users have tried adding usbcore.quirks=0bda:8153:k to
the kernel commandline and all users who have tried this report that
this fixes this.
Also note that we already have an existing NO_LPM quirk for the RTL8153
used in the Microsoft Surface Dock (where it uses a different usb-id).
This commit adds a NO_LPM quirk for the generic Realtek RTL8153
0bda:8153 usb-id, fixing the Tx timeout errors on these devices.

The num_remote_opens counter keeps track of the number of open files which must be
maintained by the server at any point. This is a per-tree-connect counter, and the value
of this counter gets displayed in the /proc/fs/cifs/Stats output as a following...
Open files: 0 total (local), 1 open on server
^^^^^^^^^^^^^^^^
As a thumb-rule, we want to increment this counter for each open/create that we
successfully execute on the server. Similarly, we should decrement the counter when
we successfully execute a close.
In this case, an increment was being missed in case of smb2_query_dir_first,
in case of successful open. As a result, we would underflow the counter and we
could even see the counter go to negative after sufficient smb2_query_dir_first calls.
I tested the stats counter for a bunch of filesystem operations with the fix.
And it looks like the counter looks correct to me.
I also check if we missed the increments and decrements elsewhere. It does not
seem so. Few other cases where an open is done and we don't increment the counter are
the compound calls where the corresponding close is also sent in the request.

Newer GCC warns about possible truncations of two generated path names as
we're concatenating the configurable sysfs and debugfs path prefixes
with a filename and placing the results in buffers of the same size as
the maximum length of the prefixes.
snprintf(d->name, MAX_STR_LEN, "gb_loopback%u", dev_id);
snprintf(d->sysfs_entry, MAX_SYSFS_PATH, "%s%s/",
t->sysfs_prefix, d->name);
snprintf(d->debugfs_entry, MAX_SYSFS_PATH, "%sraw_latency_%s",
t->debugfs_prefix, d->name);
Fix this by separating the maximum path length from the maximum prefix
length and reducing the latter enough to fit the generated strings.
Note that we also need to reduce the device-name buffer size as GCC
isn't smart enough to figure out that we ever only used MAX_STR_LEN
bytes of it.

Set the SDHCI_QUIRK2_PRESET_VALUE_BROKEN quirk flag. Otherwise, the
High Speed DDR mode on the eMMC controller (MMC_TIMING_MMC_DDR52)
would not work.
I split the platform data to give no impact to other platforms,
although the UniPhier platform is currently only the upstream user
of this IP.
The SDHCI_QUIRK2_PRESET_VALUE_BROKEN flag is set if the compatible
string matches to "socionext,uniphier-sd4hc".

On the Acer Aspire Switch 10 (SW5-012) microSD slot always reports the card
being write-protected even though microSD cards do not have a write-protect
switch at all.
Add a new DMI_QUIRK_SD_NO_WRITE_PROTECT quirk which when set sets
the MMC_CAP2_NO_WRITE_PROTECT flag on the controller for the external SD
slot; and add a DMI quirk table entry which selects this quirk for the
Acer SW5-012.

Based on a sample of 7 DSDTs from Cherry Trail devices using an AXP288
PMIC depending on the design one of 2 possible LDOs on the PMIC is used
for the MMC signalling voltage, either DLDO3 or GPIO1LDO (GPIO1 pin in
low noise LDO mode).
The Lenovo Miix 320-10ICR uses GPIO1LDO in the SHC1 ACPI device's DSM
methods to set 3.3 or 1.8 signalling voltage and this appears to work
as advertised, so presumably the device is actually using GPIO1LDO for
the external microSD signalling voltage.
But this device has a bug in the _PS0 method of the SHC1 ACPI device,
the DSM remembers the last set signalling voltage and the _PS0 restores
this after a (runtime) suspend-resume cycle, but it "restores" the voltage
on DLDO3 instead of setting it on GPIO1LDO as the DSM method does. DLDO3
is used for the LCD and setting it to 1.8V causes the LCD to go black.
This commit works around this issue by calling the Intel DSM to reset the
signal voltage to 3.3V after the host has been runtime suspended.
This will make the _PS0 method reprogram the DLDO3 voltage to 3.3V, which
leaves it at its original setting fixing the LCD going black.
This commit adds and uses a DMI quirk mechanism to only trigger this
workaround on the Lenovo Miix 320 while leaving the behavior of the
driver unchanged on other devices.

Even though INITRAMFS_SOURCE kconfig option isn't set in most of
defconfigs it is used (set) extensively by various build systems.
Commit f26661e127 ("initramfs: make initramfs compression choice
non-optional") has changed default compression mode. Previously we
compress initramfs using available compression algorithm. Now
we don't use any compression at all by default.
It significantly increases the image size in case of build system
chooses embedded initramfs. Initially I faced with this issue while
using buildroot.
As of today it's not possible to set preferred compression mode
in target defconfig as this option depends on INITRAMFS_SOURCE
being set. Modification of all build systems either doesn't look
like good option.
Let's instead rewrite initramfs compression mode choices list
the way that "INITRAMFS_COMPRESSION_NONE" will be the last option
in the list. In that case it will be chosen only if all other
options (which implements any compression) are not available.

In order to preserve backwards compatability with kmod tools, we have to
move the namespace field in Module.symvers last, as the depmod -e -E
option looks at the first three fields in Module.symvers to check symbol
versions (and it's expected they stay in the original order of crc,
symbol, module).
In addition, update an ancient comment above read_dump() in modpost that
suggested that the export type field in Module.symvers was optional. I
suspect that there were historical reasons behind that comment that are
no longer accurate. We have been unconditionally printing the export
type since 2.6.18 (commit bd5cbcedf4), which is over a decade ago now.
Fix up read_dump() to treat each field as non-optional. I suspect the
original read_dump() code treated the export field as optional in order
to support pre <= 2.6.18 Module.symvers (which did not have the export
type field). Note that although symbol namespaces are optional, the
field will not be omitted from Module.symvers if a symbol does not have
a namespace. In this case, the field will simply be empty and the next
delimiter or end of line will follow.

A lenovo pixart mouse (17ef:608d) is afflicted common the the malfunction
where it disconnects and reconnects every minute--each time incrementing
the device number. This patch adds the device id of the device and
specifies that it needs the HID_QUIRK_ALWAYS_POLL quirk in order to
work properly.
