Phoronix: Intel Linux Driver Patches Revived For Useful Per-Process Load Statistics

Just over one year ago were proposed changes to improve the insight into per-client load activity for Intel graphics under Linux. The changes would indicate how busy each Intel graphics engine (render, blitter, video, etc) was on a per-client basis and other metrics similar to what users have to look at when it comes to analyzing CPU activity. Those patches were never followed up on or merged but have been revived this past week...

That sounds ridiculously useful, I really do wish it gets implemented in all of the open source GPU drivers.

There should be a generic kernel interface supporting performance data for all possible units in all possible devices, e.g. memory controllers, network offloading engines, storage controllers, etc.

Why stop at CPU cores and GPU units?

Gotta say something like this would be very useful for a lot of devices and scenarios.

umr and radeontop already support this (at least in general, not per client)
