From: Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxx>
This series contains four main components:
1. Per client support for intel_gpu_top.
2. IGT test for per client data exposed via fdinfo from i915.
3. Extracting intel_gpu_top code into shared IGT libraries - which makes
possible to write:
4. Vendor agnostic rudimentary gputop tool.
Since I had the intel_gpu_top code for years, this flow of the series is what
I ended up with. But it also makes sense since we can have a cut point after
intel_gpu_top, in case the common drm fdinfo specification does not end up
getting enough traction.
Example of the intel_gpu_top output:
