2.4.21 Isn't working for me....

[AthlonRob]

Hello list...

I'm trying to get some cpu frequency control over my laptop's CPU with
the 2.4.21 kernel.  I'd just jump to 2.6.0-test4, but have a few pieces
of hardware that don't have drivers available for the test kernel yet.

I downloaded the versions for 2.4 dated August 24th, 25th, and also the
26th.  The ones from the 24th and 25th give the results below, the 26th
errors out during patching.

Is there a different version I should use?  Any solution to the below? 
Am I totally SOL?  :-)

I enabled cpufreq under processor options, enabling the P4 one built-in
(not as a module).  make bzImage spits forth the following:

gcc -D__KERNEL__ -I/home/rob/kernel/linux-2.4.21/include -Wall

I'd really appreciate any help you can provide... maybe a -stable
release somewhere instead of what I think are nightly cvs 'builds' ? 
:-)

The latest is again 2.4.22, _not_ 2.4.21.

Do the 2.4.22 patch works with linux.2.4.22 final or only with -rc ????

final is rc4 + makefile patch
rc4 is small delta upon rc3

So rc3, rc4 and final probably patch without rejects and rejects with 
older versions are likely easy to fix. But if there is no real reason to 
  use something before 22, please use 2.4.22.

To be more precise: this is cpufreq-2.4.22-pre6 from Dave J. (and containing
lot of updates from Dominik) found in http://www.codemonkey.org.uk/
with some portions rediffed against 2.4.22-rc4 (which is 2.4.22 in fact).

I just found http://www.codemonkey.org.uk/projects/cpufreq/ in the
archives and gave the two patches listed there a shot.

-1 and -2.

Here are the results I got from that on my make bzImage....

I tried fudging around with the files and lines mentioned, but didn't
get anywhere except more broken...  :-)

Is my system borked?  :-)

I understand the -ac sources contain the cpufreq patch already... do
y'all know if I will be able to apply preemptive multitasking, low
latency scheduling, ntfs, and acpi patches I want to add in there?  They
aren't in the test ran above, FWIW.

That's the latest from the kernel.org repository, right?  the ones with
filenames like cpufreq-LINUX_2_4-20030825.tar.gz?

The codemonkeys ones, with filenames like cpufreq-2.4.21-1.gz are
against 2.4.21... right?  :-)

I would go ahead and just upgrade to 2.4.22, except I really need (ok, I
don't need, I just really want) preempt, low-latency scheduling, and the
latest NTFS drivers in this kernel... and 2.4.22 is still too new for
any of those to be available.  :-(

I suppose I could survive without cpu frequency scaling... but the
project looks *way super cool* to me.  :-)

On http://www.gotontheinter.net/exoops/modules/mydownloads/
there's a patch with all that, plus cpufreq (I don't know which version),
for kernel 2.4.22. Plus supermount, etc.

Actually, I don't know about the NTFS driver, but, as with everything else,
really, 2.4.22 doesn't change that much and the patches for 2.4.21 would
probably work with few rejects, correctable by hand.

I've been using that kernel, but can't get swsusp to work correctly and
cpufreq doesn't work that well with my chipset, anyhow, (it's a 440BX,)
so test it throughly.

Luciano Rocha

What is the trouble with the 440BX?

Can you reproduce with latest cpufreq and 2.4.22?

Well, it's a lousy chipset, cpufreq wise.

I had it working with your help some time in the past, using a speedstep.c
and playing with the GPO.

But that driver doesn't have the same interface as normal cpufreq and then
2.4.21 merged parts of the AC tree that makes my processor frequency very
dynamic, so I end up not using it much.

But I tried the CVS version of cpufreq, but it still doesn't work.
As it is, it doesn't have a speedstep.c, only a speedstep-ich, that
fails to insert:
cpufreq: Intel(R) SpeedStep(TM) for this chipset not (yet) available.

The speedstep.c available on http://www.poupinou.org/cpufreq/index.html
also fails to insert:
speedstep.o: unresolved symbol cpufreq_setfunctions
speedstep.o: unresolved symbol cpufreq_init

Oops, correct.  I forgot that one.  Sorry.
Should happens today.

It compiled like a charm....

I haven't actually tested it yet, though, to see if it actually worked. 
:-)

I can't tell you so much.  You are using preempt and low-latency in
a SMP box, btw?  If really you need SMP, I can't tell you it will
be OK, just that you may have some dead lock unless you get the latest
one (which is not yet released completely for 2.4 tree).  Therefore,
it may be usefull if you compile with spinlock debug.
