Hello,
Im really having some trouble getting iommu/vfio-pci to work.
Im running on a supermicro X8SIE-F. I have enabled vt-d in bios.
I used dpdk-devbind so it uses vfio-pci driver, but the kernel module is
still e1000e.
I've added modules="vfio vfio-pci vfio_iommu_type1" to /etc/conf.d/modules,
and made it start on boot and i've created a udev rule. Ive also tried
https://www.kernel.org/doc/Documentation/vfio.txt but no luck.. So i hope
some one can help me getting it to work
Im on gentoo with kernel 4.8.17-hardened-r2
you need to specify the pci ids vfio-pci should bind to at start.
if you don't then it wont bind to any specific card at boot.
i don't remmeber exact syntax right now but i a good start is to read up on
Alex Williamsons blog at:
http://vfio.blogspot.com/
check the old posts there.
there is more guides and information out there regarding vfio too.
