Hello I am new to VFIO but not new to Linux. First I will post Specs then Configs/Logs
Things I’ve tried:
Pinned CPUs cores 2-7
Used isolcpus
Recompiled Manjaro Kernel with VFIO patches
Installed VirtIO drivers for all devices and Device Manager
Used MSI v2 tool to enable MSI for GPU and GPU Audio
OS:Manjaro
Kernel: Personally Compiled 5.6.11-1 with VFIO Patches.
Specs:
Gigabyte Z390 AORUS Motherboard
i7-9700KF 5.0GHz @1.35V (NOT multithreaded)
EVGA 2080 Super XC HYBRID (Passed to VM)
GT 210 ( Arch Linux Host)
EVGA 650W Gold+ PSU
