drm/amd/amdgpu embed hw_fence into amdgpu_job2021-08-16T19:16:58ZJack ZhangJack.Zhang1@amd.com2021-05-12T07:06:35Zurn:sha1:c530b02f39850a639b72d01ebbf7e5d745c60831
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

Page table entries are now in embedded in VM BO, so
we do not need struct amdgpu_vm_pt. This patch replaces
struct amdgpu_vm_pt with struct amdgpu_vm_bo_base.

drm/amdgpu: do not use drm middle layer for debugfs2021-02-18T21:43:09ZNirmoy Dasnirmoy.das@amd.com2021-02-15T20:26:45Zurn:sha1:98d28ac2f511a29d608326e50e3b1061ec18e9f3
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.
