newbie: Patch Confusion, P4 not supported?

newbie: Patch Confusion, P4 not supported?

[Simon]

Hi,

Sorry about the dumb newbie question. Can't find any docs on this.

I just upgraded to a vanilla 2.4.21 kernel, and want to add cpufreq support 
back for my Intel P4, in my Thinkpad A31p.

I had this working with 2.4.20, using the 'advanced' patch from 
http://www.brodo.de/cpufreq/, and controlling it by echo-ing stuff to 
/proc/cpufreq

I couldn't make any of the patches on www.brodo.de/cpufreq_old apply to my 
kernel cleanly. They look rather old, and the page is no longer in use. So I 
donloaded the latest patch from ftp://ftp.linux.org.uk/pub/linux/cpufreq/ 
(ftp://ftp.linux.org.uk/pub/linux/cpufreq/cpufreq-LINUX_2_4-20030617.tar.bz2) 
and applied this.

Now, it says that my cpu is unsupported. As follows:

shiro proc # dmesg | grep cpufreq
cpufreq: Intel(R) SpeedStep(TM) support $Revision: 1.7.2.6 $
cpufreq: Intel(R) SpeedStep(TM) for this processor not (yet) available.

/proc/cpufreq no longer exists.

Seems strange. It *used* to work with the old patch, but somehow has decided 
not to work with the new one. Am I missing some kernel parameter or 
something? Or has support been taken out? Or am I using the wrong patch?

Thanks
Simon

output of /proc/cpuinfo follows:

shiro linux # cat /proc/cpuinfo

Indeed. That's why it's named cpufreq_old :-) 

Fortunately, though, Dave Jones took over as maintainer. You can find an
upgraded backport of cpufreq for 2.4.21-rc8 (which is [almost] the same as
2.4.21]) at
http://www.codemonkey.org.uk/cpufreq/

Oh... The filename 20030617 made it sound pretty new... And it seemed to apply 
to 2.4.21 okay, so thought it was more recently updated.

I'm reluctant to use -ac, because the other patches I like to apply to my 
kernels don't like it too much. Is there no patch around that applies onto 
2.4.21 vanilla?

I guess it's no big deal I can go back to my old kernel for now.

This is even more older than the one you downloaded from Dominik
site...  Try the latest ac in the meantime.

That did it, thanks! :)
