This revision will only support the addition of poll delay parameter to perf OA. If needed a future revision will incorporate interrupt support. Regards, Umesh Lionel Landwerlin (4): drm/i915/perf: rework aging tail workaround drm/i915/perf: move pollin setup to non hw specific code drm/i915/perf: only append status when data is available drm/i915/perf: add new open param to configure polling of OA buffer drivers/gpu/drm/i915/i915_perf.c | 310 +++++++++++++------------ drivers/gpu/drm/i915/i915_perf_types.h | 35 +-- include/uapi/drm/i915_drm.h | 13 ++ 3 files changed, 194 insertions(+), 164 deletions(-)
