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. I other words, first three patches are enough for i915 side of things while the rest are optional.
Example of the intel_gpu_top output: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ intel-gpu-top: Intel Tigerlake (Gen12) @ /dev/dri/card0 - 220/ 221 MHz 70% RC6; 0.62/ 7.08 W; 760 irqs/s
