c52238c9fb drm/amd/pm/powerplay/smumgr: Fix PCIeBootLinkLevel value on Fiji
Previously this was initialized with zero which represented PCIe Gen
1.0 instead of using the
maximum value from the speed table which is the behaviour of all other
smumgr implementations.

fca0c66b22 drm/amd/pm: fix smu table id bound check issue in smu_cmn_update_table()
'table_index' is a variable defined by the smu driver (kmd)
'table_id' is a variable defined by the hw smu (pmfw)

This code should use table_index as a bounds check.

13ff4f63fc drm/amd/display: Don't program BLNDGAM_MEM_PWR_FORCE when CM low-power is disabled on DCN30
Before commit 33056a97ae ("drm/amd/display: Remove double checks for
`debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL)
checked the low-power debug flag before calling
dpp3_power_on_blnd_lut(false).

After commit 33056a97ae ("drm/amd/display: Remove double checks for
`debug.enable_mem_low_power.bits.cm`"), dpp3_program_blnd_lut(NULL)
unconditionally calls dpp3_power_on_blnd_lut(false). The BLNDGAM power
helper writes BLNDGAM_MEM_PWR_FORCE when CM low-power is disabled, causing
immediate SRAM power toggles instead of deferring at vupdate. This can
disrupt atomic color/LUT sequencing during transitions between
direct scanout and composition within gamescope's DRM backend on
Steam Deck OLED.

To fix this, leave the BLNDGAM power state unchanged when low-power is
disabled, matching dpp3_power_on_hdr3dlut and dpp3_power_on_shaper.

3eb8c0b4c0 drm/radeon: Remove calls to drm_put_dev()
Since the allocation of the drivers main structure was changed to
devm_drm_dev_alloc() drm_put_dev()'ing to trigger it to be free'd
should be done by devres.

However, drm_put_dev() is still in the probe error and device remove
paths. When the driver fails to probe warnings like the following are
shown because devres is trying to drm_put_dev() after the driver
already did it.

[    5.642230] radeon 0000:01:05.0: probe with driver radeon failed with error -22

3ac635367e drm/amd: Check that VPE has reached DPM0 in idle handler
[Why]
Newer VPE microcode has functionality that will decrease DPM level
only when a workload has run for 2 or more seconds.  If VPE is turned
off before this DPM decrease and the PMFW doesn't reset it when
power gating VPE, the SOC can get stuck with a higher DPM level.

This can happen from amdgpu's ring buffer test because it's a short
quick workload for VPE and VPE is turned off after 1s.

[How]
In idle handler besides checking fences are drained check PMFW version
to determine if it will reset DPM when power gating VPE.  If PMFW will
not do this, then check VPE DPM level. If it is not DPM0 reschedule
delayed work again until it is.

v2: squash in return fix (Alex)

which caused it to become negative.

cdfdec6f16 drm/amd/pm: Avoid writing nulls into pp_od_clk_voltage
Calling `smu_cmn_get_sysfs_buf` aligns the
offset used by `sysfs_emit_at` to the current page boundary, which was
previously directly returned from the various `print_clk_levels`
implementations to be added to the buffer position.
Instead, only the relative offset showing how much was written
to the buffer should be returned, regardless of how it was changed
for alignment purposes.

8c6a023473 drm/amd/display: add additional hdcp traces
[why]
Current hdcp trace only tracks hdcp errors. We need to expand the trace
structure for more tracing information.

[how]
Add following traces for hdcp1:
- attempt_count
- downstream_device_count
Add following traces for hdcp2:
- attempt_count
- downstream_device_count
- hdcp1_device_downstream
- hdcp2_legacy_device_downstream

bf95cf7f7a drm/amd/display: Fix performance regression from full updates
[Why]
full_update_required is too strict at update_planes_and_stream_state,
causing a performance regression due to too many updates being full.

[How]
* Carve out weak version of full_update_required for use inside
update_planes_and_stream_state.

03a593b1ac drm/amd/display: Remove dc state from check_update
[Why]
dc_check_update_surfaces_for_stream should not have access to entire
DC, especially not a mutable one. Concurrent checks should be able
to run independently of one another, without risk of changing state.

[How]
* Remove access to dc state other than debug and capacity.
* Move some checks from DC to DM caller.
