From the VT-d spec 8.3: If a DRHD structure with INCLUDE_PCI_ALL flag Set is reported for a Segment, it must be enumerated by BIOS after all other DRHD structures for the same Segment. However, some broken BIOS violate the rules. To bring up ACRN with them, change the ASSERT to a permissive check to unblock the BIOS limitation. Also, scan the DRHD list to find the one who has INCLUDE_PCI_ALL flag. Tracked-On: #4937 Signed-off-by: Shuo A Liu <shuo.a.liu@intel.com> |
