[Why] comparing pwm bl values (coverted) with user brightness(converted) levels in commit_tail leads to continuous setting of backlight via dmub as they don't to match. This leads overdrive in queuing of commands to DMCU that sometimes lead to depending on load on DMCU fw: "[drm:dc_dmub_srv_wait_idle] *ERROR* Error waiting for DMUB idle: status=3" [How] Store last successfully set backlight value and compare with it instead of pwm reads which is not what we should compare with.

The value actual_pix_clk_100Hz is dereferencing pointer pix_clk_params before pix_clk_params is being null checked. Fix this by assigning pix_clk_params->requested_pix_clk_100hz to actual_pix_clk_100Hz only if pix_clk_params is not NULL, otherwise just NULL. Signed-off-by:

Flush TLB needs wait for GPU update fence done. MMU notify callback to unmap range from GPUs uses unlocked GPU page table update, so add tlb_cb to unlocked update fence to increase vm->tlb_seq. Signed-off-by:

[Why] On resume we do link detection for all non-MST connectors. MST is handled separately. However the condition for telling if connector is on mst branch is not enough for mst hub case. Link detection for mst branch link leads to mst topology reset. That causes assert in dc_link_allocate_mst_payload() [How] Use link type as indicator for mst link. Reviewed-by:

[Why] In init_hw() we call init_pipes() before enabling power gating. init_pipes() tries to power gate dsc but it may fail because required force-ons are not released yet. As a result with dsc config the following errors observed on resume: "REG_WAIT timeout 1us * 1000 tries - dcn20_dsc_pg_control" "REG_WAIT timeout 1us * 1000 tries - dcn20_dpp_pg_control" "REG_WAIT timeout 1us * 1000 tries - dcn20_hubp_pg_control" [How] Move enable_power_gating_plane() before init_pipes() in init_hw() Reviewed-by:

[Why] Once DSC slice cannot fit pixel clock, we incorrectly reset min slices to 0 and allow max slice to operate, even when max slice itself cannot fit the pixel clock properly.
