Getting nvtop Snap to show GPU processes on AMD/Intel

[Nightmayr]

Hi @Syllo, I'm looking into getting the snap package to show processes on AMD and Intel GPUs. It currently doesn't work due to the current interfaces being used by nvtop lacking the AppArmor profile to access @{PROC}/[0-9]*/fdinfo/. As suggested in the snapcraft forum post I added owner @{PROC}/[0-9]*/fdinfo/ r to the snapd system-observe interface which does populate the list with processes. However the list doesn't show games on Steam run via Proton/WINE, whereas a native build does show this process. Any ideas what might be going on here? Maybe you might be aware of additional paths I need to add to the interface?
