drm/amdgpu: shadow in shadow_list without tbo.mem.start cause page fault in sriov TDR

2019-04-12T16:23:49Z

shadow was added into shadow_list by amdgpu_bo_create_shadow. meanwhile, shadow->tbo.mem was not fully configured. tbo.mem would be fully configured by amdgpu_vm_sdma_map_table until calling amdgpu_vm_clear_bo. If sriov TDR occurred between amdgpu_bo_create_shadow and amdgpu_vm_sdma_map_table, amdgpu_device_recover_vram would deal with shadow without tbo.mem.start.

drm/amdgpu: amdgpu_device_recover_vram always failed if only one node in shadow_list

2019-04-04T15:22:06Z

amdgpu_bo_restore_shadow would assign zero to r if succeeded. r would remain zero if there is only one node in shadow_list. current code would always return failure when r <= 0. restart the timeout for each wait was a rather problematic bug as well. The value of tmo SHOULD be changed, otherwise we wait tmo jiffies on each loop. Signed-off-by: Wentao Lou Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/sched: Refactor ring mirror list handling.

2019-01-25T21:15:36Z

Decauple sched threads stop and start and ring mirror list handling from the policy of what to do about the guilty jobs. When stoppping the sched thread and detaching sched fences from non signaled HW fenes wait for all signaled HW fences to complete before rerunning the jobs. v2: Fix resubmission of guilty job into HW after refactoring. v4: Full restart for all the jobs, not only from guilty ring. Extract karma increase into standalone function. v5: Rework waiting for signaled jobs without relying on the job struct itself as those might already be freed for non 'guilty' job's schedulers. Expose karma increase to drivers. v6: Use list_for_each_entry_safe_continue and drm_sched_process_job in case fence already signaled. Call drm_sched_increase_karma only once for amdgpu and add documentation. v7: Wait only for the latest job's fence.

drm: Split out drm_probe_helper.h

2019-01-24T12:20:42Z

Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.
