Hi Mark, I noticed local APIC timer is used by cbe in the current system.
And I got the following note from "Intel(r) 64 and IA-32 Architectures Software Developer's Manual Volume 3A: System Programming Guide, Part 1" ----note---- The APIC timer may temporarily stop while the processor is in deep C-states or during transitions caused by Enhanced Intel SpeedStep(r) Technology. ----note end---- Did you see the timer stop on any platform? Did you encounter any problem? I didn't see any code care about this issue during the speed transition, ;-) Thanks, -Aubrey
