Hi there,
question:
Is there a way to "blacklist" modules builtin the kernel to avoid having to build a custom kernel?
In particular the question concerns the xhci_pci module (pci passthrough) but also radeon, amdgpu, snd_hda_intel ...
I already played around with the kernel command line paramenter:
module_blacklist= [KNL] Do not load a comma-separated list of modules. Useful for debugging problem modules.
It does not seem to have any effect... at least thats was lspci -k says
kernel drivers are already blacklisted in /etc/modprobe.d/blacklist.conf
I'd really like to avoid building a custom kernel (again)
background:
I am operating a xen4.5 host (ubuntu) with Win gaming guests since a few years and am quite happy.
However, back then I had to build a custom kernel to avoid grabbing of GPU, PCI-USB-cards and connected usb devices
Recently, I am trying to migrate to arch+xen4.10+UEFI.

The lspci -k output does not show xhci_pci, radeon or amdgpu as loaded / in use.

And "modules builtin the kernel" is an oxymoron.
Here's what you never wanted to know about modules: https://wiki.archlinux.org/index.php/Kernel_modules ;-)
