The ROCm profiler would expose the data from KFD profiling APIs to application developers to tune the applications based on how the address range attributes affect the behavior and performance. Per process event log use the existing SMI (system management interface) event API. Each event log is one line of text with the event specific information. v2: * Keep existing events behaviour * Use ktime_get_boottime_ns() as timestamp to correlate with other APIs * Use compact message layout, stick with existing message convention * Add unmap from GPU event Philip Yang (8): drm/amdkfd: Correct SMI event read size drm/amdkfd: Add KFD SMI event IDs and triggers drm/amdkfd: Enable per process SMI event drm/amdkfd: Add GPU recoverable fault SMI event drm/amdkfd: add migration SMI event drm/amdkfd: Add user queue eviction restore SMI event drm/amdkfd: Add unmap from GPU SMI event drm/amdkfd: Bump KFD API version for SMI profiling event drivers/gpu/drm/amd/amdgpu/amdgpu_amdkfd.h | 7 +- .../gpu/drm/amd/amdgpu/amdgpu_amdkfd_gpuvm.c | 11 +- drivers/gpu/drm/amd/amdkfd/kfd_device.c | 4 +- drivers/gpu/drm/amd/amdkfd/kfd_migrate.c | 67 ++++--- drivers/gpu/drm/amd/amdkfd/kfd_migrate.h | 5 +- drivers/gpu/drm/amd/amdkfd/kfd_priv.h | 2 +- drivers/gpu/drm/amd/amdkfd/kfd_process.c | 37 +++- drivers/gpu/drm/amd/amdkfd/kfd_smi_events.c | 163 +++++++++++++++++- drivers/gpu/drm/amd/amdkfd/kfd_smi_events.h | 19 +- drivers/gpu/drm/amd/amdkfd/kfd_svm.c | 63 +++++-- include/uapi/linux/kfd_ioctl.h | 30 +++- 11 files changed, 343 insertions(+), 65 deletions(-) -- 2.17.1
