I'm working with Core2Duo under vxWorks 6.8
In order to put the CPU into C4 I ran the following code:
mov EAX, 0x30 (Bits 0-3 define C4 sub states)
mov ECX, 0x0
1. Where can I find full documentation on C1,C2,C3 sub states ?
I read the manual of Core2Duo but found only information on C1-C4 states. not sub states.
2. Does the High Performance Event Timer (HPET) keep ticking under C4 ?
3. Can I use ICE (e.g ARIUM) to find what is current state of the CPU ?
