Subject: Intel Core2Duo mobile - how does the VID get set?
Date: Tue, 19 Feb 2008 12:19:45 +0000 [thread overview]
Message-ID: <47BAC961.6030808@fenrir.org.uk> (raw)
After a fair bit of Googling and reading around, I'm none the wiser
about exactly how Linux 2.6.x sets the processor VID (or for that matter
how it decides the FID settings) when using the ondemand governor and
cpufreq stuff.
Can anyone tell me a) whether this is obtained from the BIOS, something
in the MSR of the processor or elsewhere and b) whether there is an
interface in /proc or /sys where one can find out what is set and modify it?
I'm not subscribed to the list so a Cc: would be appreciated, cheers!
