C2 is the 2nd idle state. The external I/O Controller Hub blocks interrupts to the processor. And so on with C3, C4, etc. I'll discuss this further down in this paper. By the way, there is nothing preventing the OS from busy waiting in its idle state, and thus keeping the processor in C0, as did older operating systems.
Yes, that's what processor.max_cstate=1 kernel command line option does. So, please use it if you have this issue. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
