VGA Aperture size #93

Open 66cobra opened 6 years ago

Is there a way to increase VGA Aperture size? I was trying to use Asus CN62 i7-5500U with IGVT-g, but it appears that the aperture is only 128MB with the current firmware, which is not enough for more than one vGPU. And I don't see any way to adjust it.

Thanks

on Haswell/Broadwell devices, both the aperture and DVMT sizes are set by the Intel blob that does RAM init. I've twiddled some bits to increase the DVMT from the stock setting of 32MB to 96MB, but haven't looked at changing the aperture.
