From: Tomita Moeko <tomitamo...@gmail.com> All gen 11 and 12 igd devices have 64 bit BDSM register at 0xC0 in its config space, add them to the list to support igd passthrough on Alder/ Raptor/Rocket/Ice/Jasper Lake platforms.
Tested legacy mode of igd passthrough works properly on both linux and windows guests with AlderLake-S GT1 (8086:4680).
