[PATCH v3 00/24] Support Host Trap Sampling for gfx941/gfx942

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



PC sampling is a form of software profiling, where the threads of an application
are periodically interrupted and the program counter that the threads are currently
attempting to execute is saved out for profiling.

David Yat Sin (5):
  drm/amdkfd/kfd_ioctl: add pc sampling support
  drm/amdkfd: add pc sampling support
  drm/amdkfd: enable pc sampling query
  drm/amdkfd: enable pc sampling create
  drm/amdkfd: set debug trap bit when enabling PC Sampling

James Zhu (19):
  drm/amdkfd: add pc sampling mutex
  drm/amdkfd: add trace_id return
  drm/amdkfd: check pcs_entry valid
  drm/amdkfd: enable pc sampling destroy
  drm/amdkfd: add interface to trigger pc sampling trap
  drm/amdkfd: trigger pc sampling trap for gfx v9
  drm/amdkfd/gfx9: enable host trap
  drm/amdgpu: use trapID 4 for host trap
  drm/amdgpu: add sq host trap status check
  drm/amdkfd: trigger pc sampling trap for arcturus
  drm/amdkfd: trigger pc sampling trap for aldebaran
  drm/amdkfd: use bit operation set debug trap
  drm/amdkfd: add setting trap pc sampling flag
  drm/amdkfd: enable pc sampling stop
  drm/amdkfd: add queue remapping
  drm/amdkfd: enable pc sampling start
  drm/amdkfd: add pc sampling thread to trigger trap
  drm/amdkfd: add pc sampling release when process release
  drm/amdkfd: bump kfd ioctl minor version for pc sampling availability
