      drm/amdgpu: introduce new amdgpu_fence object to indicate the job embedded fence · bf67014d
      Huang Rui 提交于
      The job embedded fence donesn't initialize the flags at
      dma_fence_init(). Then we will go a wrong way in
      amdgpu_fence_get_timeline_name callback and trigger a null pointer panic
      once we enabled the trace event here. So introduce new amdgpu_fence
      object to indicate the job embedded fence.

      drm/amd/amdgpu embed hw_fence into amdgpu_job · c530b02f
      Jack Zhang 提交于
      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
