Rebased and updated with more feedback from Sourab and Matt. In particular the patch that added the oa_min_timer_exponent sysctl parameter has now been replaced with one adding an oa_max_sample_rate parameter in Hz. This way userspace policy won't need to be tailored to different systems when gen9 OA is enabled where the exponents don't represent the same periods as for Haswell. - Robert Robert Bragg (11): drm/i915: Add i915 perf infrastructure drm/i915: rename OACONTROL GEN7_OACONTROL drm/i915: return EACCES for check_cmd() failures drm/i915: don't whitelist oacontrol in cmd parser drm/i915: Add 'render basic' Haswell OA unit config drm/i915: Enable i915 perf stream for Haswell OA unit drm/i915: advertise available metrics via sysfs drm/i915: Add dev.i915.perf_stream_paranoid sysctl option drm/i915: add dev.i915.oa_max_sample_rate sysctl drm/i915: Add more Haswell OA metric sets drm/i915: Add a kerneldoc summary for i915_perf.c drivers/gpu/drm/i915/Makefile | 4 + drivers/gpu/drm/i915/gvt/handlers.c | 2 +- drivers/gpu/drm/i915/i915_cmd_parser.c | 45 +- drivers/gpu/drm/i915/i915_drv.c | 9 + drivers/gpu/drm/i915/i915_drv.h | 156 +++ drivers/gpu/drm/i915/i915_oa_hsw.c | 752 ++++++++++++++ drivers/gpu/drm/i915/i915_oa_hsw.h | 38 + drivers/gpu/drm/i915/i915_perf.c | 1753 ++++++++++++++++++++++++++++++++ drivers/gpu/drm/i915/i915_reg.h | 340 ++++++- include/uapi/drm/i915_drm.h | 134 +++ 10 files changed, 3193 insertions(+), 40 deletions(-) create mode 100644 drivers/gpu/drm/i915/i915_oa_hsw.c create mode 100644 drivers/gpu/drm/i915/i915_oa_hsw.h create mode 100644 drivers/gpu/drm/i915/i915_perf.c -- 2.10.1 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
