Was experimenting GPU passthrough with QEMU (following the steps given here) on Pop!_OS and in the process I added kernel parameters.
Now I want to remove theintel_iommu=on kvm.ignore_msrs=1 vfio-pci.ids=8086:3e9b
to regain locked VGA card. However altering parameters with popos seems not working for me. I am not an advanced user so I am sure I might be missing something here.I tried (1) kernelstub, (2) updating grub and (3) modifying loader.conf (4) changing configuration (as explained here), but no luck. You can find in the screenshot that, kernelstub is reporting only
quiet splash
being the active kernel parameters, howevercmdline
shows (otherwise) currently effective options.Wondering how to alter the kernel parameters permanently so that VGA card to be returned to the host system. I had similar problem with Ubuntu, changing /etc/default/grub file and updating it easily solved it.
