[Intel-gfx] [PATCH v2 06/10] drm/i915: Enable i915 perf stream for Haswell OA unit

Gen graphics hardware can be set up to periodically write snapshots of performance counters into a circular buffer via its Observation Architecture and this patch exposes that capability to userspace via the i915 perf interface. Cc: Chris Wilson Signed-off-by: Robert
