On GC 9.4.3, DW 41 in MQD is repurposed as compute_tg_chunk_size for cooperative dispatch. When it's a AQL queue, set compute_tg_chunk_size as 1 to spread work groups evenly among XCCs. If it's PM4 queue, unset compute_tg_chunk_size to disable cooperative mode. v3: set compute_tg_chunk_size as 1 instead of #CUs per XCC v2: set compute_tg_chunk_size as #CUs per XCC instead of total wave slots per XCC Signed-off-by:

v1: Check new exception bits in TRAPSTS register Remove single step exception workaround, now part of exception bits v2: GC 9.4.3 uses ttmp11 to store {1’b0, dispatch index [24:0], wave_id_in_workgroup[5:0]}, so use ttmp13 instead of ttmp11 to preserve ib_sts.

Commit 075e2099c32c ("drm/amd/display: Fix race condition in DPIA AUX transfer") was backported to stable, which I noticed because of git saying linux-6.1/.git/rebase-apply/patch:37154: space before tab in indent. while applying patch-6.1.21.

[Why] The 6.75 GBps link rate is part of the new eDP specification version 1.5 is going to be supported in the future. Since this standard is very new and there are no existing 6.75 GBps panels on the market yet, we should put a condition in the driver on enabling this feature until we can validate it with real hardware. [How] - Add boolean flag support_eDP1_5 in struct dc_debug_options. - Enable the 6.75 link rate in reduce_link_rate(...) only when the flag is true. Reviewed-by:

[Why] Observing underflow on dcn30+ system config at 4k144hz [How] We set the UCLK hardmax on AC/DC switch if softmax is enabled and also on boot. While booting up the UCLK Hardmax is set to softmax before the init sequence and the init sequence resets the hardmax to UCLK max which enables P-state switching. Just added a conditional check to avoid setting hardmax on init. Reviewed-by:

[Why] DPP Root clock optimization when combined with 4to1 MPC combine results in the screen turning black. This is because the DPPCLK is stopped during the middle of an optimize_bandwidth sequence during commit_minimal_transition without going through plane power down/power up. [How] The intent of a 0Hz DPP clock through update_clocks is to disable the DTO. This differs from the behavior of stopping the DPPCLK entirely (utilizing a 0Hz clock on some ASIC) so it's better to move this logic to reside next to plane power up/power down where we gate the HUBP/DPP DOMAIN. The new sequence should be: Power down: PG enabled -> RCO on Power up: RCO off -> PG disabled Rename power_on_plane to power_on_plane_resources to reflect the actual operation that's occurring.
