[PATCH 2/4] drm/v3d: Add a little debugfs entry for measuring the core clock.

2018-09-28 Thread Eric Anholt
This adds just enough performance counter support to measure the clock. We don't have linux kernel drivers for the clock driving the HW, and this was useful for determining that the V3D HW is running on a slow clock, not that the driver was slow. Signed-off-by: Eric Anholt --- drivers/gpu/drm/v
