Currently Tyr's struct GpuInfo is manually copied and updated from
include/uapi/drm/panthor_drm.h. But an auto generated struct is
available, so use that instead to avoid copy/paste errors and to stay
up-to-date with the panthor uapi.

DRM_IOCTL_MODE_CREATEPROPBLOB allows userspace to allocate arbitrary-sized
property blobs backed by kernel memory.
Currently, the blob data allocation is not accounted to the allocating
process's memory cgroup, allowing unprivileged users to trigger unbounded
kernel memory consumption and potentially cause system-wide OOM.
Mark the property blob data allocation with GFP_KERNEL_ACCOUNT so that the memory
is properly charged to the caller's memcg. This ensures existing cgroup
memory limits apply and prevents uncontrolled kernel memory growth without
introducing additional policy or per-file limits.

Since commit 56de5e305d4b ("clk: renesas: r9a07g044: Add MSTOP for RZ/G2L")
we may get the following kernel panic, for some panels, when rebooting:
systemd-shutdown[1]: Rebooting.
Call trace:
...
do_serror+0x28/0x68
el1h_64_error_handler+0x34/0x50
el1h_64_error+0x6c/0x70
rzg2l_mipi_dsi_host_transfer+0x114/0x458 (P)

mipi_dsi_dcs_set_display_off_multi+0x9c/0xc4
ili9881c_unprepare+0x38/0x88
drm_panel_unprepare+0xbc/0x108
This happens for panels that need to send MIPI-DSI commands in their
unprepare() callback. Since the MIPI-DSI interface is stopped at that
point, rzg2l_mipi_dsi_host_transfer() triggers the kernel panic.
Fix by moving rzg2l_mipi_dsi_stop() to new callback function
rzg2l_mipi_dsi_atomic_post_disable().
With this change we now have the correct power-down/stop sequence:
systemd-shutdown[1]: Rebooting.

With some panels informing support for Panel Replay we are observing
problems if having Panel Replay enable bit set on sink when forced to use
PSR instead of Panel Replay. Avoid these problems by not setting Panel
Replay enable bit in sink when Panel Replay is globally disabled during
link training. I.e. disabled by module parameter.
The enable bit is still set when disabling Panel Replay via debugfs
interface. Added note comment about this.

Some GPUs like A612 doesn't use a named register range resource. This
is because the reg-name property is discouraged when there is just a
single resource.
To address this, retrieve the 'gmu' register range by its index. It is
always guaranteed to be at index 0.

The hw clock gating register sequence consists of register value pairs
that are written to the GPU during initialisation.
The a690 hwcg sequence has two GMU registers in it that used to amount
to random writes in the GPU mapping, but since commit 188db3d7fe66
("drm/msm/a6xx: Rebase GMU register offsets") they trigger a fault as
the updated offsets now lie outside the mapping. This in turn breaks
boot of machines like the Lenovo ThinkPad X13s.
Note that the updates of these GMU registers is already taken care of
properly since commit 40c297eb245b ("drm/msm/a6xx: Set GMU CGC
properties on a6xx too"), but for some reason these two entries were
left in the table.

There's no need to check a userspace-provided GT ID (which may come from
any tile) against the number of GTs that can be present on a single
tile. The xe_device_get_gt() lookup already checks that the GT ID passed
is valid for the current device.(Matt Roper)

Add a way to track the detailed DSC pipes-per-line, streams-per-pipe,
slices-per-stream configuration instead of the current streams-per-pipe
and slices-per-line value. This way describes the slice configuration in
a clearer way, for instance providing a
2 pipes-per-line x 2 streams-per-pipe x 2 slices-per-stream = 8 slices-per-line
view, instead of the current, coarser
2 streams-per-pipe, 8 slices-per-line
view, the former better reflecting that each DSC stream engine has 2
slices. This also let's optimizing the configuration in a
simpler/clearer way, for instance using 1 stream x 2 slices, or 1 stream
x 4 slices instead of the current 2 stream x 1 slice, or 2 streams x 2
slices configuration (so that 1 DSC stream engine can be powered off in
each pipe).
Follow-up changes will convert the current slices-per-line computation
logic to compute instead the above detailed slice configuration.

An LRC timestamp getting stuck is a somewhat normal occurrence. If a
single VF submits a job that does not get timesliced, the LRC timestamp
will not increment. Reduce the LRC timestamp stuck message on VFs to
notice (same log level as job timeout) to avoid false CI bugs in tests
where a VF submits a job that does not get timesliced.

clangd reports many "unused header" warnings throughout the Xe driver.
Start working to clean this up by removing unnecessary includes in our
.c files and/or replacing them with explicit includes of other headers
that were previously being included indirectly.
By far the most common offender here was unnecessary inclusion of
xe_gt.h. That likely originates from the early days of xe.ko when
xe_mmio did not exist and all register accesses, including those
unrelated to GTs, were done with GT functions.
There's still a lot of additional #include cleanup that can be done in
the headers themselves; that will come as a followup series.
v2:
- Squash the 79-patch series down to a single patch. (MattB)

[Why&How]
Right now, the HDMI HPD filter is enabled by default at 1500ms.
We want to disable it by default, as most modern displays with HDMI do
not require it for DPMS mode.
The HPD can instead be enabled as a driver parameter with a custom delay
value in ms (up to 5000ms).
Fixes: c918e75e1ed9 ("drm/amd/display: Add an HPD filter for HDMI")
Closes: https://gitlab.freedesktop.org/drm/amd/-/issues/4859

The user mode queue keeps a pointer to the most recent fence in
userq->last_fence. This pointer holds an extra dma_fence reference.
When the queue is destroyed, we free the fence driver and its xarray,
but we forgot to drop the last_fence reference.
Because of the missing dma_fence_put(), the last fence object can stay
alive when the driver unloads. This leaves an allocated object in the
amdgpu_userq_fence slab cache and triggers
This is visible during driver unload as:
BUG amdgpu_userq_fence: Objects remaining on __kmem_cache_shutdown()
kmem_cache_destroy amdgpu_userq_fence: Slab cache still has objects
Call Trace:
kmem_cache_destroy
amdgpu_userq_fence_slab_fini
amdgpu_exit
__do_sys_delete_module
Fix this by putting userq->last_fence and clearing the pointer during
amdgpu_userq_fence_driver_free().
This makes sure the fence reference is released and the slab cache is
empty when the module exits.
v2: Update to only release userq->last_fence with dma_fence_put()

This reverts commit 820b3d376e8a102c6aeab737ec6edebbbb710e04.
It’s better to validate VM TLB flushes in the flush‑TLB backend
rather than in the generic VM layer.
Reverting this patch depends on

Internal backlight levels are initialised from ACPI but the values
are sometimes out of sync with the levels in effect until there has
been a read from hardware (eg triggered by reading from sysfs).
This means that the first drm_commit can cause the levels to be set
to a different value than the actual starting one, which results in
a sudden change in brightness.
This path shows the problem (when the values are out of sync):
amdgpu_dm_atomic_commit_tail()
-> amdgpu_dm_commit_streams()
-> amdgpu_dm_backlight_set_level(..., dm->brightness[n])
This patch calls the backlight ops get_brightness explicitly
at the end of backlight registration to make sure dm->brightness[n]
is in sync with the actual hardware levels.

[Why]
DP-HDMI dongles can execeed bandwidth requirements on high resolution
monitors. This can lead to pruning the high resolution modes.
HDMI 1.3 bumped the clock to 340MHz, but display code never matched it.
[How]
Set default to (DVI) 165MHz. Once HDMI display is identified update
to 340MHz.

When an eGPU is unplugged the KFD topology should also be destroyed
for that GPU. This never happens because the fini_sw callbacks never
get to run. Run them manually before calling amdgpu_device_ip_fini_early()
when a device has already been disconnected.
This location is intentionally chosen to make sure that the kfd locking
refcount doesn't get incremented unintentionally.
