Subject: [Intel-xe] [PATCH v2 0/2] drm/xe/pmu: Enable PMU interface
Date: Tue, 27 Jun 2023 17:51:11 +0530	[thread overview]
Message-ID: <20230627122113.1472532-1-aravind.iddamsetty@intel.com> (raw)

There are a set of engine group busyness counters provided by HW which are
perfect fit to be exposed via PMU perf events.

BSPEC: 46559, 46560, 46722, 46729

events can be listed using:
perf list
  xe_0000_03_00.0/any-engine-group-busy-gt0/         [Kernel PMU event]
  xe_0000_03_00.0/copy-group-busy-gt0/               [Kernel PMU event]
  xe_0000_03_00.0/interrupts/                        [Kernel PMU event]
  xe_0000_03_00.0/media-group-busy-gt0/              [Kernel PMU event]
  xe_0000_03_00.0/render-group-busy-gt0/             [Kernel PMU event]

and can be read using:

perf stat -e "xe_0000_8c_00.0/render-group-busy-gt0/" -I 1000
           time             counts unit events

The pmu base implementation is taken from i915.

v2:
Store last known value when device is awake return that while the GT is
suspended and then update the driver copy when read during awake.
