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?
There isn't a common framework yet, its under discussion in this thread.
AMD has some stuff under /proc/<pid>/fdinfo/<fd>, and i915 at the moment
has only global GPU stats (export as a perf/PMU device, see "perf list |
grep i915.*/") used by current version of intel_gpu_top.

P.S. I suggest you use reply-to-all when replying on mailing list
threads so it's easier to spot your message.
