I've got a really old Radeon HD 6570 in my newly built server (retired gaming rig), I just need the GPU so it will boot, it's not doing any real work (if I could fully power it off after boot, that would be cool too). However It always seem so be at max fan spin, and afaik (though this is outside my expertise) it's showing up as power_state D0. Looking up GPU and proxmox in the same search always return 'passthrough' result which isn't helpful. Anyone got any ideas?
