I can confirm that it works with no issues with UEFI. I recently replaced
R9 270 by RX 480 and it even worked with not issues after I forgot to
update/remove the old ROM file for R9. Here is my command line. It uses a
few variables for multiple GPU but you should get the base picture. I have
both Windows 7 and WIndows 10 VMs and all of them work fine.
qemu-system-x86_64 -enable-kvm -cpu host -m $memoryarg -smp
sockets=1,cores=$corearg,threads=2 \
-serial none \
-ctrl-grab -no-quit \
-parallel none \
$soundarg \
-name passthrough-$1 \
-rtc base=localtime \
-drive if=pflash,format=raw,readonly,file=$folder/OVMF_CODE-pure-efi.fd \
-drive if=pflash,format=raw,file=$folder/OVMF_VARS-pure-efi.fd \
-netdev bridge,id=hn0 -device e1000,netdev=hn0,id=nic1,mac=$macaddr \
-drive file=$folder/W7_UEFI.qcow2,id=d0,if=none -device
ide-hd,drive=d0,serial=$hddserial \
-device vfio-pci,host=$vgapci \
-device vfio-pci,host=$audiopci
