drm/amdgpu: remove unsafe optimization to drop preamble ib

2021-07-19T08:04:35+00:00

[ Upstream commit 7d9c70d23550eb86a1bec1954ccaa8d6ec3a3328 ] 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.

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

2021-04-21T01:45:24+00:00

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

2021-02-18T21:43:09+00:00

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.
