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. v2: Make sure to initialize ->specific_ctx_id when opening, without relying on _pin_notify hook, in case ctx already pinned. v3: Revert back to pinning ctx upfront when opening stream, removing need to hook in to pinning and to update OACONTROL on the fly.
