drm/amd/display: Simplify brightness initialization

2023-11-29T23:01:05+00:00

[Why] Remove the brightness cache in DC. It uses a single value to represent the brightness for both SDR and HDR mode. This leads to flash in HDR on/off. It also unconditionally programs brightness as in HDR mode. This may introduce garbage on SDR mode in miniLED panel. [How] Simplify the initialization flow by removing the DC cache and taking what panel has as default. Expand the mechanism for PWM to DPCD Aux to restore cached brightness value generally.

drm/amd/display: Add z-state support policy for dcn35

2023-11-29T22:52:00+00:00

[Why] DML2 means that the dcn3x policy for calculating z-state support no longer runs from validate_bandwidth. This means we are unconditionally allowing Z8, the hardware default. [How] Port the policy over to DCN35, but with a few modifications: - Don't use min_dst_y_next_start as a check for Z8/Z10 allow - Add support for overriding the Z10 stutter period per ASIC - Cleanup the code to make the policy assignment more clear Reviewed-by: Charlene Liu Acked-by: Hamza Mahfooz Signed-off-by: Nicholas Kazlauskas Signed-off-by: Alex Deucher

drm/amd/display: Fix IPS handshake for idle optimizations

[Why] Intermittent reboot hangs are observed introduced by "Improve x86 and dmub ips handshake". [How] Bring back the commit but fix the polling. Avoid hanging in place forever by bounding the delay and ensure that we still message DMCUB on IPS2 exit to notify driver idle has been cleared.
