drm/amdgpu: Split amdgpu_device_fini into early and late

2021-05-20T03:45:49Z

Some of the stuff in amdgpu_device_fini such as HW interrupts disable and pending fences finilization must be done right away on pci_remove while most of the stuff which relates to finilizing and releasing driver data structures can be kept until drm_driver.release hook is called, i.e. when the last device reference is dropped. v4: Change functions prefix early->hw and late->sw Signed-off-by: Andrey Grodzovsky Acked-by: Christian König Reviewed-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20210512142648.666476-3-andrey.grodzovsky@amd.com

drm/amdgpu: add the sched_score to amdgpu_ring_init

drm/amdgpu: add wave limit functionality for gfx8,9

2021-02-09T20:27:04Z

Wave limiting can be use to load balance high priority compute jobs along with gfx jobs. When enabled, this will reserve ~75% of waves for compute jobs. We do not need this from gfx10 onwards because >=gfx10 has asynchronous compute tunneling to replace wave limit requirement.

drm/scheduler: Scheduler priority fixes (v2)

2020-08-18T22:20:17Z

Remove DRM_SCHED_PRIORITY_LOW, as it was used in only one place. Rename and separate by a line DRM_SCHED_PRIORITY_MAX to DRM_SCHED_PRIORITY_COUNT as it represents a (total) count of said priorities and it is used as such in loops throughout the code. (0-based indexing is the the count number.) Remove redundant word HIGH in priority names, and rename *KERNEL* to *HIGH*, as it really means that, high. v2: Add back KERNEL and remove SW and HW, in lieu of a single HIGH between NORMAL and KERNEL.

drm/amdgpu: Fix per-IB secure flag GFX hang

2020-04-28T20:20:30Z

Since commit "Move to a per-IB secure flag (TMZ)", we've been seeing hangs in GFX. We need to send FRAME CONTROL stop/start back-to-back, every time we flip the TMZ flag. That is, when we transition from TMZ to non-TMZ we have to send a stop with TMZ followed by a start with non-TMZ, and similarly for transitioning from non-TMZ into TMZ. This patch implements this, thus fixing the GFX hang. v1 -> v2: As suggested by Luben, and accept part of implemetation from this patch: - Put "secure" closed to the loop and use optimization - Change "secure" to bool again, and move "secure == -1" out of loop. v3: Small fixes/optimizations.
