<div dir="ltr"><div><div><div class="gmail_extra">Dear all,<br></div><div class="gmail_extra">following Cole's suggestions I installed the fedora-virt-preview repo and tried again with VGA <br>passthrough from [1]<br><br>
</div><div class="gmail_extra">For this setup i use a nvidia card as the primary one and a radeon hd 7850 as the passthrough device.<br></div><div class="gmail_extra"></div><br><div class="gmail_extra">However, there are no iommu_group links neither under /sys/bus/pci/devices/0000:05:00.0/ (which is my radeon card) nor under any of the other devices.<br>
<br></div><div class="gmail_extra">AFAIG it should be the vfio module which creates these links so I guess it's not working for me.<br><br></div><div class="gmail_extra">The driver loads correctly: there are no errors in dmesg and lsmod shows:<br>
vfio_pci 32063 0 <br>vfio 19210 1 vfio_pci<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">I added iommu=pt iommu=1 to grub<br></div><div class="gmail_extra"><br></div>
<div class="gmail_extra"><div class="gmail_extra">My system currently includes:<br></div><div class="gmail_extra"><br></div><div class="gmail_extra">* libvrit 1.0.6<br></div><div class="gmail_extra">* qemu 1.5.0<br></div>
<div class="gmail_extra">* kernel 3.9.6<br><br></div><div class="gmail_extra">Maybe the kernel is outdated?<br></div><div class="gmail_extra"><br></div></div><div class="gmail_extra">I know the functionality is experimental so it's just to know if I'm doing some obvious mistakes.<br>
</div><br></div>Thanks for your help,<br><br></div>Best regards,<br><div><div><div class="gmail_extra"><br></div><div class="gmail_extra">Mario<br></div><div class="gmail_extra"><br>[1] <a href="https://bbs.archlinux.org/viewtopic.php?id=162768">https://bbs.archlinux.org/viewtopic.php?id=162768</a><br>
