[BUG] WARNING: Intel GPU: Failed to initialize PMU

[dontknowhy]

Describe the bug
Intel updated their amazing/ugly intel_gpu_top and maybe they messed up btop's GPU detection.
Now I can't see my GPU usage again :(
Unless I always run it with sudo

To Reproduce
Compile it and do some setcap magic.

Expected behavior
It can detect my GPU usage without sudo.

Might I ask if this is a discrete Arc Alchemist card like an A770? Seems like a common thread with another issue I saw.

Nope, This is an Iris Xe AlderLake-P. (why not AlderLake-:P)
And I have to say GPU detection works randomly between different builds in the same commit.

Same here with Alder Lake Iris Xe. However, it does automatically show /dev/fb0 in the custom gpu name0 preference.
