|
Yang, Yu-chu
From: yuchuyang <yu-chu.yang@...>
Board inspector does not support multiple PCI segment. Stop running and throw out the message for user to disable VMD from BIOS setting. v1->v2 Refine check_pci_domains from board_inspector.py. Discard the change of dmar.py.

-----Original Message-----VMD is not the only reason why we see multiple PCI domains. You can write something like "known causes of multiple PCI domains include:" followed by a list which only contains "VMD" for now. --- Best Regards Junjie Mao sys.exit(1) |
