Uhhhh, doesnāt vfio-pci come with these options by default? Any reason to use the patch? I currently using qemu 2.9 with vfio-pci.x-pci-sub-vendor-id and vfio-pci.x-pci-sub-device-id to manually assign my GPU subsystem ID, it works well.
vfio-pci.x-pci-vendor-id and vfio-pci.x-pci-device-id also exist, use qemu-system-x86_64 -device vfio-pci,help for a full list of vfio-pci options.
Nice! I cried when they sent one to be crushed in the hydraulic press on YouTube :(. I know it was faulty but still. It would be super handy to get one of those at some point for latency testing. Perhaps a bit overkill though.
I just checked, on my old qemu 2.1 it not available (only my patched stuff), but on 2.91 i have vfio-pci.x-pci-sub-device-id , vfio-pci.x-pci-sub-vendor-id=uint32
I will try without patch in couple of days and report back.
Not overkill at all when you can calculate to the exact millisecond how fast the refresh rate of monitors above 180hz is with their fall times. Currently Level1 just uses a GH5 at 180fps.
Level1 seriously needs a Chronos 1.4 for their monitor refresh testing. I know David personally.
