I have tested that vram usage works both on my machine (intel arc a770) and on my laptop with integrated raven2 amd gpu (with changing a line to fdinfo here). Qualcomm have not implemented vram usage via fdinfo, so no vram for msm for now :).
One thing which I'm concerned about is that power usage might not work on older intel integrated gpus. The only test subject that I have is an i5-2500M and it doesn't have any gpu sensors.
