Is this code intended to run on real x86 hardware? Has it been tested on real hardware? The reason I ask is that I worked around the AP looping problem I reported earlier by replacing the PAUSE with HLT. But now test code to start a single AP fails. While I am rusty on AP startup, it seems like if the AP is left in a non-init state then another init ipi is needed. This code sends only a startup ipi. Also, the startup IPI uses a fixed vector value of 0x30. This choice assumes memory at 0x30000 is free, something that may not be true. I also didn't see where AP code was copied to 0x30000.
