From: Sourab Gupta <sourab.gupta@xxxxxxxxx> This series adds framework for collection of OA reports associated with the render command stream, which are collected around batchbuffer boundaries. Refloating the series rebased on Robert's latest patch set for 'Enabling OA unit for Gen 8 and 9 in i915 perf', which can be found here: https://patchwork.freedesktop.org/series/20084/ Since Robert's patches are being reviewed and this patch series extends his framework to collect command stream based OA metrics, it would be good to keep this work in perspective. Looking to receive feedback (and possibly r-b's :)) on the series. Since the OA reports collected associated with the render command stream, this also gives us the ability to collect other metadata such as ctx_id, pid, etc. with the samples, and thus we can establish the association of samples collected with the corresponding process/workload. These patches can be found for viewing at https://github.com/sourabgu/linux/tree/oa-6march2017 Sourab Gupta (8): drm/i915: Add ctx getparam ioctl parameter to retrieve ctx unique id drm/i915: Expose OA sample source to userspace drm/i915: Framework for capturing command stream based OA reports drm/i915: flush periodic samples, in case of no pending CS sample requests drm/i915: Inform userspace about command stream OA buf overflow drm/i915: Populate ctx ID for periodic OA reports drm/i915: Add support for having pid output with OA report drm/i915: Add support for emitting execbuffer tags through OA counter reports drivers/gpu/drm/i915/i915_drv.h | 125 ++- drivers/gpu/drm/i915/i915_gem_context.c | 3 + drivers/gpu/drm/i915/i915_gem_execbuffer.c | 6 + drivers/gpu/drm/i915/i915_perf.c | 1149 ++++++++++++++++++++++++---- include/uapi/drm/i915_drm.h | 49 ++ 5 files changed, 1184 insertions(+), 148 deletions(-) -- 1.9.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
