Hi all, One of the tool that Intel provides as part of a suite called GPA [1] is a frame analyzer. This provides a way to look at per draw call or frame workloads on the GPU through the OA hardware.
This tool relies on another library called MDAPI which requires a somewhat specific format of data exchanged through the GL_INTEL_performance_query extension. This series implements this data format exchange while also providing access to the raw delta values of the OA counters (see explanation in patch 10). I've tried to put most of this stuff in its own file so that it doesn't interact too much with the existing queries, while also keeping the accumulation logic generic enough that it remains shared code. Hopefully that's not too hairy :) Cheers, [1] : https://software.intel.com/en-us/gpa Lionel Landwerlin (11): i965: perf: default case for unknown query types i965: perf: store the hw_id of the context in the query i965: perf: store sysfs device entry into context i965: perf: reuse timescale base function from query i965: perf: count number of accumlated reports i965: perf: consolidate unmapping oa perf bo outside accumulation i965: perf: extract utility functions i965: perf: snapshot RPSTAT1 register i965: perf: read slice/unslice frequencies from OA reports i965: perf: add support for raw queries i965: perf: enable GPA query statistics src/mesa/drivers/dri/i965/Makefile.sources | 3 + src/mesa/drivers/dri/i965/brw_context.h | 6 +- src/mesa/drivers/dri/i965/brw_defines.h | 10 + src/mesa/drivers/dri/i965/brw_oa.py | 2 +- src/mesa/drivers/dri/i965/brw_performance_query.c | 683 +++++++++++---------- src/mesa/drivers/dri/i965/brw_performance_query.h | 203 +++++- .../drivers/dri/i965/brw_performance_query_mdapi.c | 435 +++++++++++++ .../drivers/dri/i965/brw_performance_query_mdapi.h | 39 ++ .../dri/i965/brw_performance_query_metrics.h | 57 ++ src/mesa/drivers/dri/i965/meson.build | 3 + 10 files changed, 1080 insertions(+), 361 deletions(-) create mode 100644 src/mesa/drivers/dri/i965/brw_performance_query_mdapi.c create mode 100644 src/mesa/drivers/dri/i965/brw_performance_query_mdapi.h create mode 100644 src/mesa/drivers/dri/i965/brw_performance_query_metrics.h -- 2.16.2 _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-dev
