Quoting Lionel Landwerlin (2017-12-18 15:19:59) > When monitoring the GPU with i915 perf, reports are tagged with a hw > id. Gem context creation tracepoints already have a hw_id field, > unfortunately you only get this correlation between a process id and a > hw context id once when the context is created.
