[Why]
Should have been picked up in 0.1.69.0 promotion commit.
[How]
Add the missing DMUB command-header definitions in dmub_cmd.h:
1. DMUB_CMD__CACP_GET_ACE_CURVE_AREA command ID.
2. Request/response data and command structs.
3. PR runtime flag bit.

[Why]
ABM does not take effect when brightness
is below twenty percent on VABC LCD panels.
[How]
Create new VESA aux path for brightness
translation functions. When VESA aux enabled
use zero-anchored linear interpolation to
translate instead of the legacy min max
backlight mapping.

Add dm_test_crtc_destroy_state_releases_stream to cover the cur->stream
branch of amdgpu_dm_crtc_destroy_state(), complementing the existing
no-stream test.
The test attaches a DC stream to the CRTC state and takes an extra stream
reference so the destroy path drops back to the KUnit-managed reference
instead of freeing the stream, then verifies exactly one reference was
released.

Add dm_test_crtc_enable_vblank_ips_restore_replay to cover the
pr->config.replay_supported side of the sr_supported OR in
amdgpu_dm_crtc_set_vblank().
The existing IPS restore test establishes self-refresh support via the PSR
version. This test instead marks the PSR version unsupported and sets
replay_supported, forcing the sr_supported computation to fall through to
the replay branch while still calling drm_crtc_vblank_restore().

Add dm_test_crtc_enable_vblank_ips_restore to cover the IPS/self-refresh
branch of amdgpu_dm_crtc_set_vblank() that calls drm_crtc_vblank_restore().
The test primes the DC with ips_support set and IPS not fully disabled, a
supported PSR version (self-refresh supported) and an immediate-disable
vblank config, so all four conditions gating the restore hold. A stub
get_vblank_timestamp hook is installed on the CRTC so the restore helper
passes its sanity check, and the enable path then runs to completion.

Add dm_test_crtc_enable_vblank_queues_work and
dm_test_crtc_disable_vblank_queues_work to cover the
vblank_control_workqueue branch of amdgpu_dm_crtc_set_vblank():
- The enable test installs a real workqueue, retains the stream and
queues the control worker, then drains it and checks the active vblank
IRQ count was incremented.
- The disable test drives the no-stream sub-branch (the stream-retain is
skipped) and checks the worker decremented the count.
Both seed the ISM so the queued worker takes no state-machine transition,
keeping coverage on the vblank accounting; the ISM state machine itself
is covered by the ISM tests.

Add coverage for the amdgpu_dm_crtc_set_vblank() paths reached through
amdgpu_dm_crtc_enable_vblank() and amdgpu_dm_crtc_disable_vblank():
- dm_test_crtc_enable_vblank_full_path: VRR-active enable that walks the
vupdate-irq branch and acquires the crtc/pageflip IRQ references.
- dm_test_crtc_enable_vblank_vupdate_busy: vupdate IRQ rejection aborts
the enable with -EBUSY.
- dm_test_crtc_enable_vblank_crtc_irq_error: crtc IRQ acquire failure
aborts the enable with -ENOENT.
- dm_test_crtc_enable_vblank_in_reset: an in-progress GPU reset returns
early before the vblank workqueue branch.
- dm_test_crtc_disable_vblank_vrr: the VRR disable path turns the vupdate
IRQ off and releases both IRQ references.

[Why]
The connector exposed a single force_yuv420_output boolean debugfs and
carried force_yuv420_output / force_yuv422_output boolean fields to force a
chroma encoding. This cannot express "force RGB" or "force YCbCr444", and
diverges from the upstream amdgpu_dm which uses a single
force_yuv_pixel_format field keyed on enum dc_pixel_encoding.
[How]
- Replace the two boolean fields with a single uint8_t
force_yuv_pixel_format holding an enum dc_pixel_encoding value
(PIXEL_ENCODING_UNDEFINED == no override).
- Replace the force_yuv420_output boolean debugfs with a read/write
force_yuv_pixel_format file that takes the encoding directly
(1=RGB, 2=YCbCr422, 3=YCbCr444, 4=YCbCr420), validated against
PIXEL_ENCODING_COUNT.
- Convert the existing readers/writers in amdgpu_dm_connector.c to the
new field, preserving current behaviour.
- Add YCbCr444 force support now that the field can express it.

[Why]
amdgpu_dm_create_validate_stream_for_sink() drove its RGB -> YUV422 ->
YUV420 chroma fallback by recursing and toggling the shared
aconnector->force_yuv420_output / force_yuv422_output fields, resetting
them after each recursive call. Those fields have no locking and the
function runs concurrently on the same connector from two paths: the
connector probe worker (->mode_valid) and a compositor's atomic check
(dm_update_crtc_state). When both run at once, one thread can clear the
override just before the other tests its exit condition, so the exit is
missed and validation loops indefinitely, hanging the modeset path.
[How]
- Replace the recursion with an explicit loop over the chroma encodings
wrapping the existing bpc walk.
- Carry the encoding/bpc selection on the stack, passed by value into
create_stream_for_sink() / fill_stream_properties_from_drm_display_mode(),
instead of mutating shared connector state.
- Derive the supported encodings and bit depths into bitmaps and drive
validation from them, gating each candidate on the sink's advertised
capability so unsupported encodings are never retried.
- Move encoding selection entirely to the caller and pass the chosen
dc_pixel_encoding into fill_stream_properties_from_drm_display_mode().

transition
[Why]
The seamless mode switch was not getting triggered during HDR to SDR
transitions, and no DPCD write was observed. Root cause analysis
revealed that incorrect panel capabilities were being reported for PSR
SU panels. Due to the wrong capabilities, the OS was not invoking the
seamless mode switch API, resulting in no DPCD communication and also
gated eDP teardown across the seamless mode switch hold.
[How]
Fixed by setting the correct power panel capabilities for PSR SU panels.
This ensures the OS receives accurate panel capability information and
triggers the seamless mode switch API as expected, restoring proper
DPCD writes during HDR to SDR transitions.
The DC commit sequence was tearing the eDP down anyway -- backlight off,
ABM disable, DPMS off, PSR/Replay enable state cleared, PHY TX off,
OTG/OPTC off; all these actions are blocked now with the
skip_implict_edp_power_control

[Why]
hdmi_frl_status_polling_work() skipped any link whose connector_signal
was not SIGNAL_TYPE_HDMI_FRL. connector_signal is not reliably set to
SIGNAL_TYPE_HDMI_FRL while a link is actually running FRL, so links that
were operating in FRL mode were skipped and their status flags never got
polled, missing link-retrain events.
[How]
Use frl_link_settings.frl_link_rate to decide whether a link is running
FRL. A non-zero rate means FRL is active, so only links with a zero rate
are skipped. This ensures every link actually operating in FRL mode is
polled for status changes.

sized to AMDGPU_DM_MAX_DISPLAY_COUNT, which matches the DRM connector

AMDGPU_DM_MAX_DISPLAY_INDEX is 31. It suggest a maximum number of

Hence we're off by one with DRM core, which supports a max of 32
connectors.
Rename AMDGPU_DM_MAX_DISPLAY_INDEX to AMDGPU_DM_MAX_DISPLAY_COUNT
to match its actual use, and increase the size to 32 to match the
originally intended size.

Allocate each ring buffer separately. A single allocation summing all
ring sizes can exceed the page allocator's MAX_ORDER limit and fail;
per-ring buffers stay small enough to satisfy. The existing allocation
style doesn't capture any ring data if the huge allocation fails.
Splitting into multiple allocations helps to capture as much data as
possible for the core dump.
A failed ring is left with a NULL buffer and skipped when formatting.

Also guard the allocation with ring_count to avoid passing 0 size to

On GFX rings, amdgpu_cs_p2_ib() passed user-supplied ib_bytes through
to ib->length_dw without a limit, while ring_emit_ib() encodes length
into packet fields. Oversized values can corrupt adjacent control bits
and destabilize command submission.
Add a per-ring IB packet size limit helper and reject command
submissions exceeding the corresponding dword limit before IB
allocation. Use the documented 20-bit limit for GFX/compute/SDMA/VPE,
and apply the MM fallback limit for other ring types.

Creating a user queue can race with a GPU reset. While recovery holds
reset_domain->sem for write, MES is unresponsive, so the ADD_QUEUE from
amdgpu_userq_map_helper() times out (-110) and an otherwise valid queue
create fails:
amdgpu: MES(0) failed to respond to msg=ADD_QUEUE
[drm:mes_userq_map [amdgpu]] *ERROR* Failed to map queue in HW, err (-110)
amdgpu: [drm] *ERROR* ... Failed to map Queue
amdgpu: [drm] *ERROR* ... Failed to create usermode queue
Take reset_domain->sem for read around the map so it runs only once MES
is back up. This mirrors amdgpu_userq_cleanup() and honors the
userq_mutex -> reset_domain->sem order; the reset path never takes
userq_mutex, so there is no deadlock.

mes_userq_reset() unmaps the queue via the low-level mes_userq_unmap()
(REMOVE_QUEUE) but does not update queue->state, so the queue still looks
MAPPED. The destroy path then issues a second, redundant REMOVE_QUEUE for
the already-removed queue; for gfx that unmap waits on an EOP that never
arrives, times out (-110) and escalates to a full GPU reset.
Mark the queue UNMAPPED on a successful reset-path unmap so destroy skips
the redundant REMOVE_QUEUE.

If a priv/bad-op fault does not match a kernel queue slot, it belongs to a
MES-scheduled user queue. Extend the shared amdgpu_gfx_handle_priv_fault()
helper introduced by commit d8ab7636160e ("drm/amd/amdgpu: remove
duplicated code in gfx_v11 and gfx_v12") to recover it: gate on
adev->gfx.disable_uq, reset a compute user queue directly from its
doorbell, and for a gfx user queue (whose IV carries no doorbell) record
the HW slot and schedule the per-IP recovery worker.
v2:
- gate on adev->gfx.disable_uq instead of !adev->enable_mes (Alex)
- document why both the doorbell (compute) and HW-slot (gfx) reset
paths are needed (Alex)
v3:
- rebase amd-staging-drm-next. adapt to the
commit 9243cf4777fc ("drm/amd/amdgpu: remove duplicated code in gfx_v11 and gfx_v12");
no functional change

drains adev->gfx.userq_priv_fault_slots, reads the doorbell back from each

A gfx priv/bad-op fault IV carries only the HW slot (ring_id), not the
faulting user queue's doorbell. Add userq_priv_fault_slots (an atomic
bitmap of faulted slots, so concurrent faults are not dropped) and
userq_priv_fault_work to struct amdgpu_gfx; a worker drains the bitmap
and reads the doorbell back from each HQD to locate and reset the queue.

Move fs_reclaim_acquire() to before all lock acquisitions to eliminate
false positive circular locking dependency warning.
This is a 7.2-cycle regression fix suitable for stable backport.
v3: Address Mikhail Gavrilov technical review:
- Clarify that fs_reclaim_acquire/release pair only REGISTERS the
fs_reclaim lock class, does NOT create a static edge when called
with no locks held
- Explain that the actual fs_reclaim -> notifier_lock edge is
established at runtime during memory reclaim -> MMU notifier path
- Add Cc: Arunpravin PaneerSelvam
v2: Address Mikhail Gavrilov review feedback:
- Fix author name: Michael -> Mikhail Gavrilov in all trailers
- Add Fixes: tag to link regression to original commit
- Add Tested-by: Mikhail Gavrilov (tested on RX 7900 XTX)
Fixes: 1d0f5838b126 ("drm/amdgpu: Add lockdep annotations for lock ordering validation")

Replace the simple exact-match loop in emit_clk_levels with a call
to smu_v14_0_0_find_clk_level() introduced in patch 1. The helper
already handles both exact and closest-match semantics.
Build a stack-local frequency table from the DPM levels (using
reverse index for SMU_MCLK since MemPstateTable stores levels
high-to-low), then call the helper once to find the active level.
The SMU reports time-filtered average frequencies that often do not
match any DPM table entry exactly. Without closest-match fallback,
MCLK, FCLK and other clocks show DPM levels but never display the
* marker, breaking userspace tools that rely on it to identify the
active frequency.

SmuMetrics_t has no DclkFrequency field but DCLK and VCLK have
separate DPM clock tables with different frequencies at each level.
Introduce smu_v14_0_0_find_clk_level(), a shared helper that
finds the closest DPM level for a given target frequency in a
frequency array.
For METRICS_AVERAGE_DCLK, use the helper to find the DPM level
whose VCLK frequency matches the reported VclkFrequency and
return the DCLK frequency at that same level index, since both
clocks share the same level count (VcnClkLevelsEnabled /
Vcn0ClkLevelsEnabled).
The original code returned 0 for METRICS_AVERAGE_DCLK, which broke
the active-level marker in pp_dpm_dclk entirely.

GPU reset reinitializes PMFW and reloads the platform power table. The
saved user policy remains valid, but suspend-only restore does not run
because adev->in_suspend is clear.
Restore the active PPT policy from SMU late initialization while the
device is in reset recovery. Route each value through the common range
validation and ASIC setter before updating PMFW.
