Hello all,
For my new coretemp driver[1], I need to execute the rdmsr on particular
processor. There is no such "global" function for that in the kernel so
far.
The per CPU msr_read and msr_write are used in following drivers:
msr.c (it is static there now)
k8-edac.c (

Can you explain this a little further? I'm fairly certain
there are places in the kernel already doing this (or similar).
In fact, I cut-n-pasted most of the above from similar code in the
powernow-k8 driver. What exactly can we deadlock on?
I wanted to change the MSR drive

Exposing the guts of the msr driver like that doesn't seem too clean.
For in-kernel use, why not just add something like this..
(note:not even compile tested)..
Well, that *is* the guts of the MSR driver.
