Intel IGD (integrated graphics) Pass Through Support - March 2016 Update
Hi all,
It's been a while since I chimed in on this topic and given some recent updates / patches from the QEMU team and some testing I've been performing, I thought it was about time I provide an update.
Background
Many Intel CPUs feature support for an on-die GPU. We refer to this as an Intel IGD (Integrated Graphics Device). This essentially means being able to supply and power graphics for a system without needing a discrete GPU (either soldered onto the chipset like with many A
I was wrapping my head around this solution for a few days now.
