The minimal sampling period is now configurable via a
dev.i915.oa_min_timer_exponent sysctl parameter.
Following the precedent set by perf, the default is the minimum that
won't (on its own) exceed the default kernel.perf_event_max_sample_rate
default of 10 samples/s.

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.

Adds a static OA unit, MUX + B Counter configuration for basic render

Hi Sourab,
As Sergio Martinez has started experimenting with this in gputop and
reported seeing lots of ENOSPC errors being reported when reading I had a
look into this and saw a few issues with how we check that there's data
available to read in command stream mode, and a I think there's a
