Hello, I found acpi spec introduces a multiprocessor wakeup structure. It seems normal udk code not support this feature. Why not support multiprocessor wakeup structure in normal udk codebase? Because OS limitations? Ovmf with tdx feature supports this feature. And linux with tdx feature support it now. best wishes -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
