Another re-post of my earlier, now slightly updated work, to expose a DRM client
hierarchy in sysfs in order to enable a top like tool:
intel-gpu-top - load avg 9.47, 3.34, 0.13; 1000/ 950 MHz; 0% RC6; 5202mW; 1206 irqs/s
rcs0 100.00% ( 0.56/ 4.78/ 3.86) |██████████████████████████████████████████████████████████████████| 0.00% wait, 0.00% sema
bcs0 17.72% ( 0.81/ 0.00/ 0.17) |███████████▋ | 0.00% wait, 0.00% sema
vcs0 61.08% ( 0.81/ 0.00/ 0.63) |████████████████████████████████████████▎ | 0.00% wait, 0.00% sema
vecs0 0.00% ( 0.00/ 0.00/ 0.00) | | 0.00% wait, 0.00% sema
PID NAME rcs0 bcs0 vcs0 vecs0

I'll post the IGT support for this as well. It requires both this series and
engine queue depth PMU RFC-ed recently.
