--- Comment #57 from Martin Wilck
The reason for this lies in how Xen manages time, which is completely different from Linux. Making C2/C3 usable under Xen on this systems of yours is certainly theoretically doable, but I see no point in spending time here - you'll have to acknowledge your system is not the youngest anymore ;-) .
Hm, the whole point of this bug report (for me) was to enable C2/C3 on this machine :-( If I am reading the code correctly, the main difference between Xen and Linux is that Linux completely avoids using the TSC where it is unstable or otherwise unreliable. Xen, OTOH, always uses TSC, and just uses the "platform timer" to calibrate and adjust TSC when it isn't stable. -- 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.
