[Bug 432809] C1 state unsupported on modern AMD mobile CPUs

https://bugzilla.novell.com/show_bug.cgi?id=432809 User trenn@novell.com added comment https://bugzilla.novell.com/show_bug.cgi?id=432809#c8 --- Comment #8 from Thomas Renninger 2008-10-08 16:53:08 MDT --- AFAIK, through MSR you can only check whether C1E is supported and disable/enable it. I remember testing power consumption when C1E was disabled via MSR (as a workaround for an old kernel) and enabled. I definitely saw a power consumption change. That would mean (and it is more or less the only possibility from OS view) that C1E worked.

I've been trying to ask tech.support@amd.com for some technical help, but I was told that 'Linux is not officially supported'... Yeah, but this is practically for every Windows only supported model. I mean it's the support, they have to ask you this and then say good bye if the answer is Linux.

Joachim told me he has some news for C1E for me. He could add you into CC if you are interested. It is great to see people getting involved. -- 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.
