[tesla-dev] Local APIC Timer issue

[Li, Aubrey]

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
