[why] creating a generic helper for AMD specific PSR-SU sink validation. Moving the function to the power module to reference it across all OS. [how] - drop PSRSU specific sink validation helper and move to power module by reading PSR version and other PSR caps - call the new helper from linux DM (amdgpu_dm_psr) Acked-by:

[Why] When booting, the driver waits for the MPC idle bit to be set as part of pipe initialization. However, on some systems this occurs before OTG is enabled, and since the MPC idle bit won't be set until the vupdate signal occurs (which requires OTG to be enabled), this never happens and the wait times out. This can add hundreds of milliseconds to the boot time. [How] Do not wait for mpc idle if tg is disabled Reviewed-by:

Instead of the 'amdgpu_ring_priority_level' type, the 'amdgpu_gfx_pipe_priority' type was used, which is an error when setting ring priority. This is a minor error, but may cause problems in the future. Instead of AMDGPU_RING_PRIO_2 = 2, we can use AMDGPU_RING_PRIO_MAX = 3, but AMDGPU_RING_PRIO_2 = 2 is used for compatibility with AMDGPU_GFX_PIPE_PRIO_HIGH = 2, and not change the behavior of the code.

Commit 34452ac3 ("drm/amdgpu: don't use BACO for reset in S3 ") doesn't help, so the issue is something different. Assuming that to make HDA resume to D0 fully realized, it needs to be successfully put to D3 first.

"Pre-multiplied" is the default pixel blend mode for KMS/DRM, as documented in supported_modes of drm_plane_create_blend_mode_property(): https://cgit.freedesktop.org/drm/drm-misc/tree/drivers/gpu/drm/drm_blend.c In this mode, both 'pixel alpha' and 'plane alpha' participate in the calculation, as described by the pixel blend mode formula in KMS/DRM documentation: out.rgb = plane_alpha * fg.rgb + (1 - (plane_alpha * fg.alpha)) * bg.rgb Considering the blend config mechanisms we have in the driver so far, the alpha mode that better fits this blend mode is the _PER_PIXEL_ALPHA_COMBINED_GLOBAL_GAIN, where the value for global_gain is the plane alpha (global_alpha). With this change, alpha property stops to be ignored. It also addresses Bug: https://gitlab.freedesktop.org/drm/amd/-/issues/1734 v2: * keep the 8-bit value for global_alpha_value (Nicholas) * correct the logical ordering for combined global gain (Nicholas) * apply to dcn10 too (Nicholas) Signed-off-by:

Use rcu_read_lock to read p->event_idr concurrently with other readers and writers. Use p->event_mutex only for creating and destroying events and in kfd_wait_on_events. Protect the contents of the kfd_event structure with a per-event spinlock that can be taken inside the rcu_read_lock critical section. This eliminates contention of p->event_mutex in set_event, which tends to be on the critical path for dispatch latency even when busy waiting is used. It also eliminates lock contention in event interrupt handlers. Since the p->event_mutex is now used much less, the impact of requiring it in kfd_wait_on_events should also be much smaller. This should improve event handling latency for processes using multiple GPUs concurrently. v2: Reschedule the worker periodically to avoid soft lockup warnings Signed-off-by:
