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.

Thanks for reply. Since i am making a new build i am looking for proper
motherboard. One i sided with is from asus, but it seems asus
motherboards do not support switching primary GPU. I might go with
gigabyte if there is no way to solve this. I am not sure yet though.

Okay this is unexpected luck. After more tinkering i got it to work!
Here is my setup:
* AMD FX-8350 CPU + Sabertooth 990FX R2 motherboard
* :01:00.0 - gpu in first slot
* :06:00.0 - gpu in third slot
* UEFI on host and guest.
* Archlinux

In order to make host use non-boot GPU:
I think i got half-way there.. My primary gpu is at :01:00.0 and
secondary on :06:00.0. I used following xorg config:
Section "Device"
Identifier "Device0"
Driver "radeon"
VendorName "AMD Corporation"
BoardName "AMD Secondary"
BusID
That's something you should fix in the BIOS. The boot GPU is special
because the motherboard has to use it to display things such as POST
messages and such, so it's already "tainted" by the time the kernel gets
a hold of it. I had to put my guest GPU on my motherboard's second PCI
slot because
Hey is it possible to make kernel use GPU other than one that is in
first slot? If so - how?
I have multiple PCIe slots but only first can run at max speed so i
would like to use it for VGA passthrough. However if i put powerful GPU
into the first slot - linux boots using that GPU. I would like
