[Intel-gfx] [PATCH i-g-t] i915/perf: Find the associated perf-type for a particular device
Chris Wilson
chris at chris-wilson.co.uk
Sun Jan 5 01:06:43 UTC 2020
Since with multiple devices, we may have multiple different perf_pmu
each with their own type, we want to find the right one for the job.
The tests are run with a specific fd, from which we can extract the
appropriate bus-id and find the associated perf-type. The performance
monitoring tools are a little more general and not yet ready to probe
all device or bind to one in particular, so we just assume the default
igfx for the time being.
v2: Extract the bus address from out of sysfs
