Tried this version on Skylake on Linux 4.16, and it works. Engines "busy" metric
behaves as expected. Render/3D goes up when something intensive happens on
a screen. Video goes up when I use VA-API-enabled video players, and increases
when I increase speed there. Blitter is typically at 0%, since I use "modesetting" driver.
When using "intel" driver instead, I can see Blitter metric changing too.
Haven't seen VideoEnhance to go over 0%, but that's probably due to the player not
using it at all. Power usage and frequency numbers are also having values I'd expect.

Output looks neat, and overall it works great. Thanks!
