My point is that it doesn't have to be during boot, it could be after userland started a least a bit. > I can find the other cpus (the local apic and ioapic) from ACPI tables, but > after this I need to send an IPI to enable them, and configure their lapic and > ioapic. Sure, the actual implementation needs to be in the kernel. I just mean we can avoid the complex ACPI stuff part in the kernel by just using a user-level implementation. Samuel
