Re: [vfio-users] Stability Testing/Benchmarking software for Windows VMs

It's been a long time since I did it, but I remember 3Dmark (commercial and free versions) having a looping mode, and I know Furmark was a real GPU killer last time I looked. If you have an eVGA graphics card, their Precision software includes a multiple-test-type version of Furmark built in. On

Re: [vfio-users] Stability issues with GTX 970 and GTX 660, Nvidia driver crashes often, seemingly under load

I initially declined to post, but I think it's even more relevant now. I just had to replace my GTX 970 for very similar symptoms. While using it via vfio/passthrough, I'd occasionally see the screen go black or freeze, but the VM was responsive (sound, network working). I ended up taking a backup

Re: [vfio-users] Boot using second GPU?

I'm using an Asus Z97 board and a Gigabyte Z97 board currently, and both allow for switching the boot GPU between PCIE1, PCIE[2-5] or the iGPU. All slots are one ACS group, though. On Sun, Aug 7, 2016 at 10:14 AM, Rokas Kupstys wrote: > Thanks for reply. Since i am making a new

Well, I'd been considering getting a Z170 setup, if I do, I now know what vendor. Kudos indeed. On Thu, Sep 22, 2016 at 2:55 PM, Alex Williamson < alex.l.william...@gmail.com> wrote: > On Thu, Sep 22, 2016 at 12:47 PM, Nick Sarnie > wrote: > >> Hi again, >> >> Very much

Re: [vfio-users] USB >>port<< passthrough

Just to chime in, yes and no. You can't pass a port, you can pass a single device, but it's best to pass a whole USB controller. I also picked up a USB PCIe card for vfio use, it has two USB 3.0 ports on the PCI bracket and a header for two front mounted ports, and I have labels from my Brother

Re: [vfio-users] threadripper slowness

You need to tweak NUMA because your previous CPU was not NUMA, and your new one is. Having the VM running on some CPU cores on one physical package, but accessing ram that's attached to other CPU cores on a different package can cause a lot of overhead. You want to avoid that. On Wed, Aug 14,
