[vfio-users] How to choose a compatible motherboard?

[Eddie Yen]

Of course, here is my lspci -vvv and find /sys/kernel/iommu_groups

I can work perfectly about VFIO without ACS Override patch
My guess is, the High-End performance platform had same features of server
platform, that means both X79/X99 and C606 got ACS features.
But it also depends on CPU, because all Intel CPU got PCI-E controller
bulit-in CPUs. All it got ACS feature for X79.

Anyway, I also want to solve PCI boot problem, because my BIOS doesn't have
PCI graphic boot up selection.
So, I'm try to boot up with 3rd PCI-E slot, so that both 1st and 2nd PCI-E
slot can mount into VM (because PCI-E x16, 3rd PCI-E slot and above only
got x8.)
