Fred Gao b66c7cdedd vfio/pci: Bypass IGD init in case of -ENODEV ... [ Upstream commit e4eccb853664de7bcf9518fb658f35e748bf1f68 ] Bypass the IGD initialization when -ENODEV returns, that should be the case if opregion is not available for IGD or within discrete graphics device's option ROM, or host/lpc bridge is not found. Then use of -ENODEV here means no special device resources found which needs special care for VFIO, but we still allow other normal device resource access.
