drm/amdgpu: Increase direct IB pool size

2021-09-14T19:56:49Z

Direct IB pool is used for vce/vcn IB extra msg too. Increase its size to AMDGPU_IB_POOL_SIZE. v2: Squash in unused variable removal Signed-off-by: xinhui pan Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amd/amdgpu embed hw_fence into amdgpu_job

2021-08-16T19:16:58Z

Why: Previously hw fence is alloced separately with job. It caused historical lifetime issues and corner cases. The ideal situation is to take fence to manage both job and fence's lifetime, and simplify the design of gpu-scheduler. How: We propose to embed hw_fence into amdgpu_job. 1. We cover the normal job submission by this method. 2. For ib_test, and submit without a parent job keep the legacy way to create a hw fence separately. v2: use AMDGPU_FENCE_FLAG_EMBED_IN_JOB_BIT to show that the fence is embedded in a job. v3: remove redundant variable ring in amdgpu_job v4: add tdr sequence support for this feature. Add a job_run_counter to indicate whether this job is a resubmit job. v5 add missing handling in amdgpu_fence_enable_signaling Signed-off-by: Jingwen Chen Signed-off-by: Jack Zhang Reviewed-by: Andrey Grodzovsky Reviewed by: Monk Liu Signed-off-by: Alex Deucher

drm/amdgpu: Don't flush/invalidate HDP for APUs and A+A

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.
