      drm/amdgpu: add support for IP discovery gc_info table v2 · 5e713c6a
      Alex Deucher authored
      Used on gfx9 based systems. Fixes incorrect CU counts reported
      in the kernel log.

      drm/amdgpu: When the VCN(1.0) block is suspended, powergating is explicitly enabled · b7865173
      chen gong authored
      Play a video on the raven (or PCO, raven2) platform, and then do the S3
      test. When resume, the following error will be reported:
      
      amdgpu 0000:02:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring
      vcn_dec test failed (-110)
      [drm:amdgpu_device_ip_resume_phase2 [amdgpu]] *ERROR* resume of IP block
      <vcn_v1_0> failed -110
      amdgpu 0000:02:00.0: amdgpu: amdgpu_device_ip_resume failed (-110).
      PM: dpm_run_callback(): pci_pm_resume+0x0/0x90 returns -110
      
      [why]
      When playing the video: The power state flag of the vcn block is set to
      POWER_STATE_ON.
      
      When doing suspend: There is no change to the power state flag of the
      vcn block, it is still POWER_STATE_ON.
      
      When doing resume: Need to open the power gate of the vcn block and set
      the power state flag of the VCN block to POWER_STATE_ON.
      But at this time, the power state flag of the vcn block is already
      POWER_STATE_ON. The power status flag check in the "8f2cdef drm/amd/pm:
      avoid duplicate powergate/ungate setting" patch will return the
      amdgpu_dpm_set_powergating_by_smu function directly.
      As a result, the gate of the power was not opened, causing the
      subsequent ring test to fail.
      
      [how]
      In the suspend function of the vcn block, explicitly change the power
      state flag of the vcn block to POWER_STATE_OFF.

      drm/amdgpu: introduce new amdgpu_fence object to indicate the job embedded fence · bf67014d
      Huang Rui authored
      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.
