[vfio-users] Passthru of one GPU with a PC with 2 identical GPUs installed

Hi, I have a PC with two identical GPUs. One I wish to hand over to vfio and do passthru with, the other I wish the host to use. I know about commands like: echo 1002 687f >/sys/bus/pci/drivers/vfio-pci/new_id But those will cause both GPUs to be claimed by vfio. I would prefer to do it by slot,

Re: [vfio-users] Question about integrated GPU passthrough and initialization

Hi, I have had fun recently trying to get vega gpu passthru working. After a lot of testing and some kernel patching I would say: 1) if you want vega gpu reset working, use kernel 5.1.5 or above in the guest as well as the host. 2) if you want passthru working instead of a blank screen at vm start

Re: [vfio-users] Why Windows response so late to USB mouse cursor in VFIO VM?

Hi, Another approach is via events. ... You will need to edit the above to match your specific keyboard and mouse. You then press left-CTRL and right-CTRL at the same time to switch mouse/key control between VM and not. On Mon, 10 Jun 2019 at 05:45, Acewind wrote:

[vfio-users] Question about iommu groups

Hi, In the following list of iommu groups, I am wondering why sub-functions on the same PCIe card are not being given the same IOMMU group as I would expect. For example, I would have expected the GPU and the HMDI Audio for that GPU to be in the same IOMMU group. I am asking, because, with the c

Hi, You have a BIOS dated: DMI: HP ProLiant DL360 Gen9, BIOS P89 11/03/2014 It looks very old to me. I would update it to the latest and try again. On Fri, 22 Nov 2019 at 20:32, Venumadhav Josyula wrote: > > Yes, it is that way and I have enabled it. > > On Fri, 22 Nov, 2019, 11:39 pm A de Beus,

Hi, I have a threadripper cpu. I had some problems some time ago with passthru of a AMD Vega GPU. I was doing a passthru to a Linux VM. I don't know if the below fix will help a Nvidia GPU, but thought I would mention it in case. A change was needed to qemu to get it working. With the AMD Vega GPU
