drm/amd/display: add ODM case when looking for first split pipe

2023-06-14T09:16:55+00:00

commit 59de751e3845d699e02dc4da47322b92d83a41e2 upstream. [Why] When going from ODM 2:1 single display case to max displays, second odm pipe needs to be repurposed for one of the new single displays. However, acquire_first_split_pipe() only handles MPC case and not ODM case [How] Add ODM conditions in acquire_first_split_pipe() Add commit_minimal_transition_state() in commit_streams() to handle odm 2:1 exit first, and then process new streams Handle ODM condition in commit_minimal_transition_state() Cc: Mario Limonciello Cc: Alex Deucher Cc: stable@vger.kernel.org Acked-by: Stylon Wang Signed-off-by: Samson Tam Reviewed-by: Alvin Lee Tested-by: Daniel Wheeler Signed-off-by: Alex Deucher Signed-off-by: Greg Kroah-Hartman

drm/amd: Disallow s0ix without BIOS support again

2023-06-14T09:16:55+00:00

commit 30c3d3b70aba2464ee8c91025e91428f92464077 upstream. commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") showed improvements to power consumption over suspend when s0ix wasn't enabled in BIOS and the system didn't support S3. This patch however was misguided because the reason the system didn't support S3 was because SMT was disabled in OEM BIOS setup. This prevented the BIOS from allowing S3. Also allowing GPUs to use the s2idle path actually causes problems if they're invoked on systems that may not support s2idle in the platform firmware. `systemd` has a tendency to try to use `s2idle` if `deep` fails for any reason, which could lead to unexpected flows. The original commit also fixed a problem during resume from suspend to idle without hardware support, but this is no longer necessary with commit ca4751866397 ("drm/amd: Don't allow s0ix on APUs older than Raven") Revert commit cf488dcd0ab7 ("drm/amd: Allow s0ix without BIOS support") to make it match the expected behavior again.
