Description

Current implementation allows IOMMU to automatically enable certain PCI features that require IOMMU co-ordination. For various reasons to ensure ordering etc. But new use cases such as Scalable IOV, and also a way to quirk behavior due to bugs could be managed on the device vs adding a certain quirk table and such. Provides more control to support new requirements from modern devices such as devices that support SIOV.

I agree to abide by the anti-harassment policy I agree
