[Intel-gfx] [PATCH 0/7] Per client engine busyness

[Maxime Schmitt]

Hi,

Nice to see something like this being worked on.

I wrote a top-like tool some time back (nvtop).
I targeted NVIDIA, because it was the GPU I had at the time. Also,
their driver provides a nice library to retrieve the information from
(NVML).

Seeing this thread I think it would be nice to support more vendors now
that the information is available.

I took a look at the DRM documentation, but I am only finding the in-
kernel functions and not what is being exposed to user space. Maybe I
am searching at the wrong place.
Is there some documentation, from the user space point of view, on the
way to discover the GPUs and the metrics that are exposed?

Regards,
Maxime
