drm/amd: Don't reset dGPUs if the system is going to s2idle
An A+A configuration on ASUS ROG Strix G513QY proves that the ASIC reset for handling aborted suspend can't work with s2idle. This functionality was introduced in commit daf8de0874ab5b ("drm/amdgpu: always reset the asic in suspend (v2)"). A few other commits have gone on top of the ASIC reset, but this still doesn't work on the A+A configuration in s2idle. Avoid doing the reset on dGPUs specifically when using s2idle. Fixes: daf8de0874ab5b ("drm/amdgpu: always reset the asic in suspend (v2)") Link: https://gitlab.freedesktop.org/drm/amd/-/issues/2008 Reviewed-by: Alex Deucher <alexander.deucher@amd.com> Signed-off-by: Mario Limonciello <mario.limonciello@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
