Hybrid Graphics on t2 macbooks

Where'd the bit on enabling the iGPU go????

It's here now.

Quirks for VFIO gpu passthrough on a MacBookPro16,1:

  1. The Arch wiki has a very good article on this, follow it, add what is mentioned here, and that ought to get this working for you. You can ask on the t2 Linux discord if you have issues.
  2. Isolate AMDGPU from boot with vfio-pci.ids=1002:7340 in kernel parameters (add to /etc/default/grub). If you have a different gpu, check lspci -nn|grep AMD and use your gpu's id. This does make the dGPU use more power than if it wasn't isolated. You don't need to bother with the audio component here.
  3. Install the vendor-reset kernel module (aur: vendor-reset-dkms-git), load it as early as possible (add to /etc/modules-load.d/).
  4. USB and Thunderbolt controllers are in same iommu group as the GPU (at least for MBP 16,1). Pass through the two USB controllers, But don't pass through the Thunderbolt controllers (GPU driver fails in Windows guest if you do).
  5. Thunderbolt controllers must be disabled before the VM boots, i.e. sudo virsh nodedev-detach pci_0000_08_00_0 && sudo virsh nodedev-detach pci_0000_7e_00_0. This means everything in the iommu group is passed through or inactive. You can reattach them with virsh nodedev-reattach after the VM shuts down if you'd like.
  6. When USB controllers are passed through, some USB devices are still accessible by the host. It seems to be everything connected to a USB-A port on a hub that is still accesable to the host.
  7. GPU hostdev element in libvirt xml must have managed='no', i.e. <hostdev mode='subsystem' type='pci' managed='no'>. This stops it from handing the GPU back to Linux and putting in a state where it can't be given back to Windows. This lets you reboot the VM.
  8. If you can't install normal AMDGPU drivers in your Windows guest, use the Bootcamp support software drivers. Get them from Bootcamp Assistant in macOS, transfer the folder to Windows, and run WindowsSupport/BootCamp/Drivers/AMD/AMDGraphics/Setup.exe.
  9. Intel GVT-G is working.

No warranty, idk what I'm doing.

ok it worked once and now it's getting error 43 for the amdgpu, rip

Ok it was the fact that i passed through the usb-c ports?

ok if i don't passthrough thunderbolt ports it's fine; time to play video game i guess

ok so vendor reset doesn't seem to work? could be the apple specific gpu having quirks. It does work as long as linux doesn't touch the amd gpu and if you don't reboot the vm.

Thanks for documenting your progress. I'm following closely (here and on t2linux Discord), will try the same soon.

Seems to be consistent if i either lock the screen or use dri prime.

Genshin, locked screen. I think this is specific to my MacBook, if someone else has the same problem, please comment here or tell me in the t2linux discord, it'll give me more motivation to figure out what's happening.

My running theory is that it's caused by the dgpu doing complex things when there's nothing for it to directly output to (i.e. dri_prime has no display connected to the dgpu, when the display is off it might go into a powersaving mode that disconnects it).

I can consistently reproduce:

  1. Open game
  2. swaymsg "output * dpms off"
  3. wait a few minutes, it crashes

I need to figure out what games are doing in causing this, other games do it too.

amdgpu.bapm=0 amdgpu.msi=0 amdgpu.dpm=0 amdgpu.aspm=0 amdgpu.runpm=0 seems to fix it, need to figure out which one it was but i'll do that later

amdgpu.dpm=0 fixes it without too much impact on battery life. Games feel a bit slower with dri_prime, i need to see if that's just dri_prime or if disabling dpm has an impact.

I had similar issues with my MacBook Pro 16,1. For instance, when I try to change the resolution, the device freezes with a black screen then automatically reboots with CATERR message, applying amdgpu.dpm=0 fixed it
