Hi all, I am trying to do some troubleshooting where virsh commands hang after certain operations. After some googling people had success by enabling MSI on their passthrough devices. I am attempting to do this on my GTX 1080 though it doesn't seem to be working. According to the pre-check commands MSI available.
It says Enable- so that means it is currently disabled, but since it is even listed that should mean I can enable it: lspci -v -s 0000:00:05.0 .... [68] MSI: Enable- Count=1/1 Maskable- 64bit+ Kernel driver in use: nvidia And I can see it here as a param for the nvidia kernel module: modinfo nvidia .... NVreg_EnableMSI:int Currently I have attempted to enable it by adding options nvidia NVreg_EnableMSI=1 to both /etc/modules and /etc/modprobe.d/nvidia.conf (file I had to create). I have also tried running: sudo modprobe nvidia NVreg_enableMSI=1 and echo 1 | sudo tee /sys/bus/pci/devices/$mydevice/msi_bus However, after each method (and subsequent reboot) running the lspci -v -s command still says Enable-. Any tips or help would be appreciated. Thanks
