Not much interest for the common specification?

For reference I've just posted the intel-gpu-top adaptation required to parse it here: https://patchwork.freedesktop.org/patch/446041/?series=90464&rev=2.

Note that this is not attempting to be a vendor agnostic tool but is adding per client data to existing i915 tool which uses PMU counters for global stats.

intel-gpu-top: Intel Skylake (Gen9) @ /dev/dri/card0 -  335/ 339 MHz;  10% RC6;  1.24/ 4.18 W;      527 irqs/s
