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 the
intel_iommu=on kvm.ignore_msrs=1 vfio-pci.ids=8086:3e9bto 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 splashbeing the active kernel parameters, however
cmdlineshows (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.
