Hi, I'm starting to re-code apic_startup() armed with the knowqledge we've gained the last several days. One of the things I want to do is use real timing loops. Is there a kernel facility available at the point apic_startup() is called (middle of init386() in machdep.c) that will give me blocking delays in the order of 10 usec to 10 msec? Failing that does anyone see any reason why I shouldn't use the APIC timer? Is it currently used on the boot CPU for anything else? -- Steve Passe | powered by smp@csn.net | FreeBSD
