From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx> During some performance analysis I have noticed that currently our trace points are in a bit of a mess, especially the ones relating to requests. This series attempts to tidy some of that and also adds some new trace points. These new trace points are usable to analyze the engine utilization and also look at how the scheduler resolves dependencies and fences, how much time requests spend being blocked, and so on. With some post-processing the new trace points can be used to generate request and engine timeline graphs like for example the on on this URL: https://people.freedesktop.org/~tursulin/trace-demo.html If people find this interesting we could also merge the post-processing tool to IGT. Although ideally, someone more versed in GUI development could pick up on the general idea an implement something better than the not very scalable or precise JS library I have used to prototype this. Current way of getting to the graphs is essentially: perf record -e <list-of-events> -a -c 1 binary-to-be-traced perf script | trace.pl >output.html Tvrtko Tvrtko Ursulin (8): drm/i915/tracepoints: Tidy request event class drm/i915/tracepoints: Adjust i915_gem_ring_dispatch drm/i915/tracepoints: Tidy i915_gem_request_wait_begin drm/i915/tracepoints: Remove unused i915_gem_request_complete drm/i915/tracepoints: Add request submit and execute tracepoints drm/i915/tracepoints: Rename i915_gem_request_notify drm/i915/tracepoints: Add backend level request in and out tracepoints drm/i915/tracepoints: Add hw_id to context tracepoints drivers/gpu/drm/i915/Kconfig.debug | 11 +++ drivers/gpu/drm/i915/i915_gem_execbuffer.c | 4 +- drivers/gpu/drm/i915/i915_gem_request.c | 2 + drivers/gpu/drm/i915/i915_guc_submission.c | 2 + drivers/gpu/drm/i915/i915_irq.c | 2 +- drivers/gpu/drm/i915/i915_trace.h | 122 ++++++++++++++++++++++++----- drivers/gpu/drm/i915/intel_lrc.c | 4 + 7 files changed, 124 insertions(+), 23 deletions(-) -- 2.7.4 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
