I can’t even figure out how to tell if it’s supported or not. If it is supported, I can’t figure out how to enable it. If it is enabled, idk where I should be seeing it in proxmox!

Can anyone point me in the right direction?

    sorry this took so long… you know, life. trying that command altogether, I get this response: -bash: acpidump: command not found

    trying just egrep “DMAR|IVRS” (in case they are two commands) seems to hang the terminal session.

    I tried following a guide to enable PICe passthrough and get this. One important thing, there is no discrete GPU at the moment, I’m trying to pass through an HBA…
