vfio/pci: Make IGD support a configurable option (08ca1b52) · Commits · 戴 / test

Allow the code which provides extensions to support direct assignment of Intel IGD (GVT-d) to be compiled out of the kernel if desired. The config option for this was previously automatically enabled on X86, therefore the default remains Y. This simply provides the option to disable it even for X86. Signed-off-by:

		Support for Intel IGD specific extensions to enable direct
		assignment to virtual machines. This includes exposing an IGD
		specific firmware table and read-only copies of the host bridge
		and LPC bridge config space.

		To enable Intel IGD assignment through vfio-pci, say Y.
