4 weeks agodrm/amd/display: Only restore backlight after amdgpu_dm_init or dm_resume

drm/amd/display: Only restore backlight after amdgpu_dm_init or dm_resume

On clients that utilize AMD_PRIVATE_COLOR properties for HDR support,
brightness sliders can include a hardware controlled portion and a
gamma-based portion. This is the case on the Steam Deck OLED when using
gamescope with Steam as a client.

When a user sets a brightness level while HDR is active, the gamma-based
portion and/or hardware portion are adjusted to achieve the desired
brightness. However, when a modeset takes place while the gamma-based
portion is in-use, restoring the hardware brightness level overrides the
user's overall brightness level and results in a mismatch between what
the slider reports and the display's current brightness.

To avoid overriding gamma-based brightness, only restore HW backlight
level after boot or resume. This ensures that the backlight level is
set correctly after the DC layer resets it while avoiding interference
with subsequent modesets.

Alexander Usyskin [Fri, 5 Sep 2025 15:49:46 +0000 (21:19 +0530)] 
mei: late_bind: add late binding component driver

Introduce a new MEI client driver to support Late Binding firmware
upload/update for Intel discrete graphics platforms.

Late Binding is a runtime firmware upload/update mechanism that allows
payloads, such as fan control and voltage regulator, to be securely
delivered and applied without requiring SPI flash updates or
system reboots. This driver enables the Xe graphics driver and other
user-space tools to push such firmware blobs to the authentication
firmware via the MEI interface.

The driver handles authentication, versioning, and communication
with the authentication firmware, which in turn coordinates with
the PUnit/PCODE to apply the payload.

This is a foundational component for enabling dynamic, secure,
and re-entrant configuration updates on platforms like Battlemage.

potential retry goto targets, although strictly only one

drm/xe: Fix error handling if PXP fails to start

we need to cleanup what was done in that function in case of a PXP
start error.
__xe_exec_queue_init calls the submission backend init() function,
so we need to introduce an opposite for that. Unfortunately, while
we already have a fini() function pointer, it performs other
operations in addition to cleaning up what was done by the init().
Therefore, for clarity, the existing fini() has been renamed to
destroy(), while a new fini() has been added to only clean up what was
done by the init(), with the latter being called by the former (via
xe_exec_queue_fini).

GuC it already knows is not there. So fix that up.

As a stop-gap and to help with debug of load failures due to invalid
GuC init params, a wedge call had been added to the inner GuC load
function. The reason being that it leaves the GuC log accessible via
debugfs. However, for an end user, simply aborting the module load is
much cleaner than wedging and trying to continue. The wedge blocks
user submissions but it seems that various bits of the driver itself
still try to submit to a dead GuC and lots of subsequent errors occur.
And with regards to developers debugging why their particular code
change is being rejected by the GuC, it is trivial to either add the
wedge back in and hack the return code to zero again or to just do a
GuC log dump to dmesg.

v2: Add support for error injection testing and drop the now redundant
wedge call.

drm/amd/display/dml2: Guard dml21_map_dc_state_into_dml_display_cfg with DC_FP_START

dml21_map_dc_state_into_dml_display_cfg calls (the call is usually
inlined by the compiler) populate_dml21_surface_config_from_plane_state
and populate_dml21_plane_config_from_plane_state which may use FPU.  In

Thus it needs to be guarded with DC_FP_START.  But we must note that the
current code quality of the in-kernel FPU use in AMD dml2 is very much
problematic: we are actually calling DC_FP_START in dml21_wrapper.c
here, and this translation unit is built with CC_FLAGS_FPU.  Strictly
speaking this does not make any sense: with CC_FLAGS_FPU the compiler is
allowed to generate FPU uses anywhere in the translated code, perhaps
out of the DC_FP_START guard.  This problematic pattern also occurs in
at least dml2_wrapper.c, dcn35_fpu.c, and dcn351_fpu.c.  Thus we really
need a careful audit and refactor for the in-kernel FPU uses, and this
patch is simply whacking a mole.  However per the reporter, whacking
this mole is enough to make a 9060XT "just work."

drm/amd/display: Keep PLL0 running on DCE 6.0 and 6.4

DC can turn off the display clock when no displays are connected
or when all displays are off, for reference see:
- dce*_validate_bandwidth

DC also assumes that the DP clock is always on and never powers
it down, for reference see:
- dce110_clock_source_power_down

In case of DCE 6.0 and 6.4, PLL0 is the clock source for both
the engine clock and DP clock, for reference see:
- radeon_atom_pick_pll
- atombios_crtc_set_disp_eng_pll

Therefore, PLL0 should be always kept running on DCE 6.0 and 6.4.
This commit achieves that by ensuring that by setting the display
clock to the corresponding value in low power state instead of
zero.

This fixes a page flip timeout on SI with DC which happens when

This patch modifies the user queue management to use preempt/restore
operations instead of full map/unmap for queue eviction scenarios where
applicable. The changes include:

1. Introduces new helper functions:
   - amdgpu_userqueue_preempt_helper()
   - amdgpu_userqueue_restore_helper()

2. Updates queue state management to track PREEMPTED state

3. Modifies eviction handling to use preempt instead of unmap:
   - amdgpu_userq_evict_all() now uses preempt_helper
   - amdgpu_userq_restore_all() now uses restore_helper

The preempt/restore approach provides better performance during queue
eviction by avoiding the overhead of full queue teardown and setup.
Full map/unmap operations are still used for initial setup/teardown
and system suspend scenarios.

amdgpu_userq_restore_helper/amdgpu_userq_preempt_helper for consistency. (Alex)

5 weeks agodrm/amd/display: Add DSC padding for OVT Support
Relja Vojvodic [Thu, 4 Sep 2025 19:38:24 +0000 (15:38 -0400)] 
drm/amd/display: Add DSC padding for OVT Support

[Why]
-Certain OVT timings require DSC configurations which divide the
horizontal active unevenly across DSC slices
-DSC slices must be even, so padding needs to be added to the active
to make this possible
-The pixel clock of the HW now needs to be increased to accommodate
the extra padded pixels
-To keep the line time the same, the blank of the HW timing needs to
be increased as well

[How]
-Calculate h_active padding, h_total padding, and pixel clock based
off of the original OVT timing and DSC calculations
-Store these values in the pipe and program HW with these modifications
-Added general support for cases where DSC slice config does not evenly
split the horizontal active by fixing some slice width calculations
-Updated PPS calculations for these cases

5 weeks agodrm/amd/display: Add fallback path for YCBCR422
Mario Limonciello [Wed, 27 Aug 2025 17:17:19 +0000 (12:17 -0500)] 
drm/amd/display: Add fallback path for YCBCR422

[Why]
DP validation may fail with multiple displays and higher color depths.
The sink may support others though.

[How]
When DP bandwidth validation fails, progressively fallback through:
- YUV422 8bpc (bandwidth efficient)
- YUV422 6bpc (reduced color depth)
- YUV420 (last resort)

This resolves cases where displays would show no image due to insufficient
DP link bandwidth for the requested RGB mode.

SMU hang can occur if the interrupts are not enabled appropriately,
causing a vblank timeout.

This patch reverts commit 5009628d8509 ("drm/amd/display: Remove unnecessary
amdgpu_irq_get/put"), but only for RX6xxx & RX7700 GPUs, on which the

This will re-enable interrupts regardless of whether the user space needed
it or not.
