drm/amdgpu: use polling mem to set SDMA3 wptr for VF

2017-12-12T19:45:47Z

On Tonga VF, there're 2 sources updating wptr registers for sdma3: 1) polling mem and 2) doorbell. When doorbell and polling mem are both enabled on sdma3, there will be collision hit in occasion between those two sources when ucode and h/w are doing the updating on wptr register in parallel. Issue doesn't happen on CP GFX/Compute since CP drops all doorbell writes when VF is inactive. So enable polling mem and don't use doorbell for SDMA3.

drm: move amd_gpu_scheduler into common location

2017-12-07T16:51:56Z

This moves and renames the AMDGPU scheduler to a common location in DRM in order to facilitate re-use by other drivers. This is mostly a straight forward rename with no code changes. One notable exception is the function to_drm_sched_fence(), which is no longer a inline header function to avoid the need to export the drm_sched_fence_ops_scheduled and drm_sched_fence_ops_finished structures.

drm/amdgpu: busywait KIQ register accessing (v4)

2017-10-19T19:27:19Z

Register accessing is performed when IRQ is disabled. Never sleep in this function. Known issue: dead sleep in many use cases of index/data registers. v2: - wrap polling fence functions. - don't trigger IRQ for polling in case of wrongly fence signal. v3: - handle wrap round gracefully. - add comments for polling function v4: - don't return negative timeout confused with error code Signed-off-by: pding Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: add framework for HW specific priority settings v9

2017-10-09T20:30:21Z

Add an initial framework for changing the HW priorities of rings. The framework allows requesting priority changes for the lifetime of an amdgpu_job. After the job completes the priority will decay to the next lowest priority for which a request is still valid. A new ring function set_priority() can now be populated to take care of the HW specific programming sequence for priority changes. v2: set priority before emitting IB, and take a ref on amdgpu_job v3: use AMD_SCHED_PRIORITY_* instead of AMDGPU_CTX_PRIORITY_* v4: plug amdgpu_ring_restore_priority_cb into amdgpu_job_free_cb v5: use atomic for tracking job priorities instead of last_job v6: rename amdgpu_ring_priority_[get/put]() and align parameters v7: replace spinlocks with mutexes for KIQ compatibility v8: raise ring priority during cs_ioctl, instead of job_run v9: priority_get() before push_job() Reviewed-by: Christian König Acked-by: Christian König Signed-off-by: Andres Rodriguez Signed-off-by: Alex Deucher

drm/amdgpu: map compute rings by least recently used pipe

2017-09-28T20:03:22Z

This patch provides a guarantee that the first n queues allocated by an application will be on different pipes. Where n is the number of pipes available from the hardware. This helps avoid ring aliasing which can result in work executing in time-sliced mode instead of truly parallel mode.
