Adds support for per-client engine busyness stats i915 exports in sysfs
and produces output like the below:
==========================================================================
intel-gpu-top - 935/ 935 MHz; 0% RC6; 14.73 Watts; 1097 irqs/s
Could we get "gpu / pkg Watts" pretty please?
Sure, next week or so.
Are irq/s interesting with execlists? Originally the idea was to say how
many times clients were sleeping and being woken up. Now we interrupt
to wipe the gpu's nose when it sneezes.

Apart from the existing physical engine utilization it now also shows
utilization per client and per engine class.

We need to somehow pull the right card.
Yeah, as I said RFC and reference only. :)
Nothing shocking here. Where's the intel-gpu-overlay integration? ;)
Maybe intel-gpu-overlay should become an output plugin for intel_gpu_top. :)
