Some Plantronics headset as the below send an unexcept opposite
volume key's HID report for each volume key press after 200ms, like
unecepted Volume Up Key following Volume Down key pressed by user.
This patch adds a quirk to hid-plantronics for these devices, which
will ignore the second unexcepted opposite volume key if it happens
within 220ms from the last one that was handled.
Plantronics EncorePro 500 Series (047f:431e)
Plantronics Blackwire_3325 Series (047f:430c)
The patch was tested on the mentioned model, it shouldn't affect
other models, however, this quirk might be needed for them too.
Auto-repeat (when a key is held pressed) is not affected per test
result.

Create a helper function that can be used to dump the GuC log to dmesg
in a manner that is reliable for extraction and decode. The intention
is that calls to this can be added by developers when debugging
specific issues that require a GuC log but do not allow easy capture
of the log - e.g. failures in selftests and failues that lead to
kernel hangs.
Also note that this is really a temporary stop-gap. The aim is to
allow on demand creation and dumping of devcoredump captures (which
includes the GuC log and much more). Currently this is not possible as
much of the devcoredump code requires a 'struct xe_sched_job' and
those are not available at many places that might want to do the dump.

The dump of the CT buffers was only showing the unprocessed data which
is not generally useful for saying why a hang occurred - because it
was probably caused by the commands that were just processed. So save
and dump the entire buffer but in a more compact dump format. Also
zero fill it on allocation to avoid confusion over uninitialised data
in the dump.

Add a worker function helper for asynchronously dumping state when an
internal/fatal error is detected in CT processing. Being asynchronous
is required to avoid deadlocks and scheduling-while-atomic or
process-stalled-for-too-long issues. Also check for a bunch more error
conditions and improve the handling of some existing checks.
v2: Use compile time CONFIG check for new (but not directly CT_DEAD
related) checks and use unsigned int for a bitmask, rename
CT_DEAD_RESET to CT_DEAD_REARM and add some explaining comments,
rename 'hxg' macro parameter to 'ctb' - review feedback from Michal W.
Drop CT_DEAD_ALIVE as no need for a bitfield define to just set the
entire mask to zero.
v3: Fix kerneldoc
v4: Nullify some floating pointers after free.
v5: Add section headings and device info to make the state dump look
more like a devcoredump to allow parsing by the same tools (eventual
aim is to just call the devcoredump code itself, but that currently
requires an xe_sched_job, which is not available in the CT code).
v6: Fix potential for leaking snapshots with concurrent error
conditions (review feedback from Julia F).
v7: Don't complain about unexpected G2H messages yet because there is
a known issue causing them. Fix bit shift bug with v6 change. Add GT
id to fake coredump headers and use puts instead of printf.

Split the GuC log dump into a two stage snapshot and print mechanism.
This allows the log to be captured at the point of an error (which may
be in a restricted context) and then dump it out later (from a regular
context such as a worker function or a sysfs file handler).
Also add a bunch of other useful pieces of information that can help
(or are fundamentally required!) to decode and parse the log.
v2: Add kerneldoc and fix a couple of comment typos - review feedback
from Michal W.
v3: Move chunking code to this patch as it makes the deltas simpler.
Fix a bunch of kerneldoc issues.
v4: Move the CS frequency out of the coredump snapshot function into
the debugfs only code (as that info is already part of the main
devcoredump). Add a header to the debugfs log to match the one in the
devcoredump to aid processing by a unified tool. Add forcewake to the
GuC timestamp read so it actually works.

Add an extra stage to the GuC log print to copy the log buffer into
regular host memory first, rather than printing the live GPU buffer
object directly. Doing so helps prevent inconsistencies due to the log
being updated as it is being dumped. It also allows the use of the
ASCII85 helper function for printing the log in a more compact form
than a straight hex dump.
v2: Use %zx instead of %lx for size_t prints.
v3: Replace hexdump code with ascii85 call (review feedback from
Matthew B). Move chunking code into next patch as that reduces the
deltas of both.
v4: Add a prefix to the ASCII85 output to aid tool parsing.

There is a need to include the GuC log and other large binary objects
in core dumps and via dmesg. So add a helper for dumping to a printer
function via conversion to ASCII85 encoding.
Another issue with dumping such a large buffer is that it can be slow,
especially if dumping to dmesg over a serial port. So add a yield to
prevent the 'task has been stuck for 120s' kernel hang check feature
from firing.
v2: Add a prefix to the output string. Fix memory allocation bug.
v3: Correct a string size calculation and clean up a define (review

The xe_guc_exec_queue_snapshot is not really a GuC internal thing and
is definitely not a GuC CT thing. So give it its own section heading.
The snapshot itself is really a capture of the submission backend's
internal state. Although all it currently prints out is the submission
contexts. So label it as 'Contexts'. If more general state is added
later then it could be change to 'Submission backend' or some such.
Further, everything from the GuC CT section onwards is GT specific but
there was no indication of which GT it was related to (and that is
impossible to work out from the other fields that are given). So add a
GT section heading. Also include the tile id of the GT, because again
significant information.
Lastly, drop a couple of unnecessary line feeds within sections.
v2: Add GT section heading, add tile id to device section.

Commit c938ab4da0eb ("net: phy: Manual remove LEDs to ensure correct
ordering") correctly fixed a problem with using devm_ but missed
removing the LED entry from the LEDs list.
This cause kernel panic on specific scenario where the port for the PHY
is torn down and up and the kmod for the PHY is removed.
On setting the port down the first time, the assosiacted LEDs are
correctly unregistered. The associated kmod for the PHY is now removed.
The kmod is now added again and the port is now put up, the associated LED
are registered again.
On putting the port down again for the second time after these step, the
LED list now have 4 elements. With the first 2 already unregistered
previously and the 2 new one registered again.
This cause a kernel panic as the first 2 element should have been
removed.
Fix this by correctly removing the element when LED is unregistered.

(which is pretty much equivalent to s2idle). We can check in_s0ix, to
prevent the system from entering idle optimizations before it actually

[Why]
Since the surface/stream update flags aren't cleared after applying
updates, those same updates may be applied again in a future call to
update surfaces/streams for surfaces/streams that aren't actually part
of that update (i.e. applying an update for one surface/stream can
trigger unintended programming on a different surface/stream).
For example, when an update results in a call to
program_front_end_for_ctx, that function may call program_pipe on all
pipes. If there are surface update flags that were never cleared on the
surface some pipe is attached to, then the same update will be
programmed again.
[How]
Clear the surface and stream update flags after applying the updates.

This commit applies isolation enforcement to the GFX and Compute rings
in the gfx_v10_0 module.
The commit sets `amdgpu_gfx_enforce_isolation_ring_begin_use` and
`amdgpu_gfx_enforce_isolation_ring_end_use` as the functions to be
called when a ring begins and ends its use, respectively.
`amdgpu_gfx_enforce_isolation_ring_begin_use` is called when a ring
begins its use. This function cancels any scheduled
`enforce_isolation_work` and, if necessary, signals the Kernel Fusion
Driver (KFD) to stop the runqueue.
`amdgpu_gfx_enforce_isolation_ring_end_use` is called when a ring ends
its use. This function schedules `enforce_isolation_work` to be run
after a delay.
These functions are part of the Enforce Isolation Handler, which
enforces shader isolation on AMD GPUs to prevent data leakage between
different processes.

When updating connector under drm_edid infrastructure, many calculations
and validations are already done and become redundant inside AMD driver.
Remove those driver-specific code in favor of the DRM common code.

Replace raw edid handling (struct edid) with the opaque EDID type
(struct drm_edid) on amdgpu_dm_connector for consistency. It may also
prevent mismatch of approaches in different parts of the driver code.

[Why]
Initialize the new backlight_level_params structure as part of the ABC
framework, the information in this structure is needed to be passed down
to the DMCUB to identify the backlight control type, to adjust the
backlight of the panel and to perform any required conversions from PWM
to nits or vice versa.
[How]
Created initial framework of the backlight_level_params struct and
modified existing functions to include the new structure.

[Why]
Idle worker thread serves for periodic detection of HPD while system is in IPS2.
Currently it is used in headless and static screen scenarios.
IPX can be configured not to execute IPS2 for static screen.
In this case idle worker is redundant.

Only use periodic detection for static screen if IPS is fully enabled.

This is caused by lost memory during early init phase. First time driver
is removed, memory is freed but when second time the driver is inserted,
VBIOS dmub is not active, since the PSP policy is to retain the driver
loaded version on subsequent warm boots. Hence, communication with VBIOS
DMUB fails.
Fix this by aborting further communication with vbios dmub and release
the memory immediately.
