gen12/13 igpu SR-IOV support #143

Closed purplepalmdash closed 8 months ago

purplepalmdash commented 1 year ago

Building dkms from this repository and also from strongtz/i915-sriov-dkms for enable igpu SR-IOV in different reference platform, got different result under the same configuration(qemu 7.1/win10 version).

Officially intel says gen11 igpu doesn't support SR-IOV, but using this dkms it could be turned on, interesting. So I guess maybe this repository's dkms may also working on gen12/13's igpu?

Could you please help viewing igpu SR-IOV related code and let it runs properly on gen12/gen13? Thanks

@purplepalmdash , KMD backport is intended for Discrete platforms only and we do not test igpu with dkms and neither claim to support.
