You are doing your math correctly. However, not all platforms may have this perfect 1MHz clock. That means the microsecond resolution clock needs to be derived off of a faster ticking hardware clock. That's where we need to be more careful about polling intervals against the hardware source clock. Anyway, it's not impossible; tick rates just need to be worked out. -Aaron -- coreboot mailing list: [email protected] http://www.coreboot.org/mailman/listinfo/coreboot
