Looking for an mx150 VBIOS
Here's a nice little tool if you're having trouble extracting your own vbios.

anyone got 'em x17r2 3080ti vbios?
I used this method: https://github.com/kyokenn/vbios_from_reg

Extra stuff you might want to try if you still have issues: - Extract the vbios from windows (GPU-Z or with this script to get it from registry in windows. - Check with GOPUpd script to see if you have a UEFI GOP (check post2 of the forum for the script, you may also want to read the first post to understand what the script does, basically just drop your vbios into the .bat executable and follow through) - In case your vbios contains a UEFI GOP, you do not need to update, just use it as it is - In case your vbios does not contain a UEFI GOP, install one according to your device's family (Pascal) - add just above the bottom of the passed device and change /path/to/vBIOS.rom to where your vBIOS is (note that sometimes, qemu may not be able to access the file because of apparmor, so use some other place that qemu can use like /usr/share/edk2-ovmf/x64/ or /usr/share/vbios or something or add an exception for it in apparmor)

[Experiences][Potentially a guide] GVT + dGPU passthrough on a laptop (Thinkpad P50 - Muxed)
The keys for my setup were the proper PCIe location in the VM and passing a GOP updated vBIOS, otherwise I'll be met with Error 43 or no display. To get the M2000M working properly: (I assume you've read Archlinux's wiki about OVMF GPU Passthrough and how to add stuff like qemu commands in a virsh xml) - Dump the vBIOS (there are many ways, through the windows registry (manually or with a script) or by using VBiosExtractor following this guide. Note that you will need to put the full path to the BIOS updater executable, the VBiosExtractor script doesn't seem to do well with relative paths. - Add UEFI GOP to it (as it's PC-AT only) (I used Maxwell MXM) - Patch the OVMF image with the regular (or GOP updated) vBIOS by building it automatically (thanks to @Ashymad's original gist) if you're on an Arch-based OS (you'll have to download the whole gist) or check the PKGBUILD and make the patching manually (this guide has the same steps too, don't forget the dos2unix commands, otherwise the patches wont be applied). You might want to add the path of the OVMF in /etc/libvirtd/qemu.conf accordingly or edit the PKGBUILD to copy them to /usr/share/edk2-ovmf/x64/ instead (where the edk2-ovmf official package store them). - Make a VM with virt-manager as you would normally, add the dGPU and the other hardware that comes with it (for me only Audio, for others it may be also USB or others peripherals that come with a GPU nowadays), but in the XML section (make sure you enable editing), remove all PCI addressing lines (to avoid conflicting addresses) and add the proper address for the dGPU to the hostdev section (note that it usually just means that the source address and the hostdev address match). When applying, virsh will properly populate the other addresses. xml

Cheap gpu for system?
Yes but that's a different kettle of fish. You then don't need two gpus, although if you do it can be useful. Start here and see how deep the rabbit hole goes https://github.com/joeknock90/Single-GPU-Passthrough

How to disable nvidia drivers?
Im assuming you're on a single gpu setup and, as such are trying to do single gpu passthrough with a single nvidia card. so you'll likely have to run some libvirt hooks or smth to run scripts to unbind your gpu once you start your vm. In which case id suggest going through these two guides 1 2 which go over completely passing through your single gpu when you start your vm

How to install hooks (for GPU passthrough)
Out of curiosity, who is Muta, the video dude, or the guide writer, or someone else? From the GitHub it sounded like running the commands from the guide would create a qemu.d/[VM Name]/prepare/begin/start.sh . If I were to simply create those directories myself, and then script as described in the video, I should be good?
