drm/amdgpu: detach ring priority from gfx priority

2021-09-01T20:55:11Z

Currently AMDGPU_RING_PRIO_MAX is redefinition of a max gfx hwip priority, this won't work well when we will have a hwip with different set of priorities than gfx. Also, HW ring priorities are different from ring priorities. Create a global enum for ring priority levels which each HWIP can use to define its own priority levels.

drm/amdgpu: rework context priority handling

2021-09-01T20:55:11Z

To get a hardware queue priority for a context, we are currently mapping AMDGPU_CTX_PRIORITY_* to DRM_SCHED_PRIORITY_* and then to hardware queue priority, which is not the right way to do that as DRM_SCHED_PRIORITY_* is software scheduler's priority and it is independent from a hardware queue priority. Use userspace provided context priority, AMDGPU_CTX_PRIORITY_* to map a context to proper hardware queue priority. Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: Use delayed work to collect RAS error counters

2021-05-27T16:23:06Z

On Context Query2 IOCTL return the correctable and uncorrectable errors in O(1) fashion, from cached values, and schedule a delayed work function to calculate and cache them for the next such IOCTL. v2: Cancel pending delayed work at ras_fini(). v3: Remove conditionals when dealing with delayed work manipulation as they're inherently racy.

drm/amdgpu: Don't query CE and UE errors

2021-05-27T16:22:19Z

On QUERY2 IOCTL don't query counts of correctable and uncorrectable errors, since when RAS is enabled and supported on Vega20 server boards, this takes insurmountably long time, in O(n^3), which slows the system down to the point of it being unusable when we have GUI up.

drm/amdgpu: fix fence calculation (v2)

2021-05-13T18:09:12Z

The proper metric for fence utilization over several contexts is an harmonic mean, but such calculation is prohibitive in kernel space, so the code approximates it. Because the approximation diverges when one context has a very small ratio compared with the other context, this change filter out ratios smaller that 0.01% v2: make the fence calculation static and initialize variables within that function v3: Fix warnings (Alex) Reviewed-by: Alex Deucher Signed-off-by: David M Nieto Signed-off-by: Alex Deucher Link: https://patchwork.freedesktop.org/patch/msgid/20210513174539.27409-2-david.nieto@amd.com
