drm/amdgpu: remove unsafe optimization to drop preamble ib

2021-06-02T02:55:39Z

Take the situation with gfxoff, the optimization may cause corrupt CE ram contents. In addition emit_cntxcntl callback has similar optimization which firmware can handle properly even for power feature. Signed-off-by: Jiansong Chen Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: fix no full coverage issue for gprs initialization

2021-04-29T03:36:05Z

The wave's number per simd in aldebaran is changed to 8, so it is impossible to use old algorithm to initiate all sgprs with one threadgroup. The new algorithm firstly use three threadgroups to initiate most sgprs simultaneously and then use another threadgroup with 4 waves to cover other uninitiated sgprs. v2: Add more description about the new algorithm to clear sgprs and add some comment for shader binaries Signed-off-by: Dennis Li Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: Add mem sync flag for IB allocated by SA

2021-04-21T01:45:24Z

The buffer of SA bo will be used by many cases. So it's better to invalidate the cache of indirect buffer allocated by SA before commit the IB. Signed-off-by: Jinzhou Su Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: do not use drm middle layer for debugfs

2021-02-18T21:43:09Z

Use debugfs API directly instead of drm middle layer. This also includes following debugfs file output changes: 1 amdgpu_evict_vram/amdgpu_evict_gtt output will not contain any braces. e.g. (0) --> 0 2 amdgpu_gpu_recover output will print return value of amdgpu_device_gpu_recover() instead of not so important "gpu recover" message. v2: * checkpatch.pl: use '0444' instead of S_IRUGO. * remove S_IFREG from mode. * remove mode variable.

drm/amdgpu: enable gfx wave limiting for high priority compute jobs

2021-02-09T20:27:11Z

Enable gfx wave limiting for gfx jobs before pushing high priority compute jobs so that high priority compute jobs gets more resources to finish early. v2: use ring priority instead of job priority.

drm/amdgpu: drm_device to amdgpu_device by inline-f (v2)

2020-08-24T17:06:06Z

Get the amdgpu_device from the DRM device by use of an inline function, drm_to_adev(). The inline function resolves a pointer to struct drm_device to a pointer to struct amdgpu_device. v2: Use a typed visible static inline function instead of an invisible macro.
