It looks like APs are woken up, because the test IPI is delivered. I just need to have the OS_BOOT_RENDEZ do sufficient initializations. I don't think I have any DTR enties because I couldn't see any data on the screen when writing to the frame-buffer as a way to see if the AP actually woke up. BTW: I moved scanning the MADT to a place where it now happens to be called only when SMP is defined. This is bogus. I probably broke non SMP configs :-/ -- Marcel Moolenaar USPA: A-39004 marcel@xcllnt.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
