[please CC your replies, because i'm not subscribed]
I'm testing 2.6.0-test1 on my HP nx9005 Laptop (using a Mobile AMD Athlon XP)
But i can't get the sysfs interface of CPUFreq part to show up. I then
recomplied the kernel with both old (obsolete) /proc interfaces enabled. The old
interfaces both show up, but seem to be not working (but the is my first try to
get CPUFreq working with any kernel version). I googled around for hours
without finding any useful information for this case.
Anyway, /proc/sys/cpu/0/{speed,speed-max,speed-min} are all 0 when i cat them.
If i cat /proc/cpufreq i get:
Badness in kobject_get at lib/kobject.c:378

minimum CPU frequency - maximum CPU frequency - policy
The last line output by cat, the rest are kernel messages.
/sys/devices/system/cpu/cpu0/ is just an empty directory, it even does not
contain a 'name' file.
I can echo > to /proc/cpufreq and /proc/sys/cpu/0/speed without any
result (i.e. no speed change as far as i can tell).
The powernow driver detects the CPU.

Form bootup messages:
powernow: AMD K7 CPU detected.
powernow: PowerNOW! Technology present. Can scale: frequency and voltage.

My .config attached.. Hope that will help you..
With this setup I have /sys/devices/system/cpu/cpu0/cpufreq/ and it's all
working perfectly. I am also using a Mobile AMD Athlon XP.

I tried your config (with just one change, i enabled reiserfs, i use it for my
root fs) but It's the same. /sys/devices/system/cpu/cpu0/ is just empty, no
change.
I tried with gcc 2.95.4 (as shipped with debian testing) and gcc 3.3.1 (same)
but neither solved to problem.
What else could be the Problem? I assume problems loading modules or such
userspace problems can't cause this behaviour?
Any help diagnosing the problem appricatied,
Martin H.

What's the output [if any] in "dmesg" starting with either "cpufreq" or
"powernow"?
I guess it's yet another BIOS problem... [as seen quite often wrt AMD
PowerNow, unfortunately]

I included some more information about my system in my first mail, but anyway.
the IMHO relevant dmesg messages are:
Machine check exception polling timer started.
powernow: AMD K7 CPU detected.
powernow: PowerNOW! Technology present. Can scale: frequency and voltage.
powernow: Found PSB header at c00f17f0
powernow: Table version: 0x12
powernow: Flags: 0x0 (Mobile voltage regulator)
powernow: Settling Time: 100 microseconds.
powernow: Has 14 PST tables. (Only dumping ones relevant to this CPU).
Enabling SEP on CPU 0
I did a little bit of investigation in the kernel source (powernow-k7.c) and
downloaded x86info. The Output of x86info --pm --bios with the following
clueless little patch.

So it seems to me that the BIOS doesn't have the tables for my Athlon
model/stepping. I tried to get a new bios from hp, but it didn't change anything
relevant (they changed something in the PSTs but did not add a new one for my
processor)

I think it would be a good thing to display a Message explaining why powernow
isn't working to the user in the case that no relevant PST is found.
Can you suggest any workaround for this problem, or is my only option to
complain to HP do supply an updated BIOS.
I very much would like to have a way to override (or add to) the bios provided
values. BTW windows XP somehow manages to use powernow on this laptop anyway.

Indeed, that's the BUG().

Well, you could try using the PST which mostly matches your system except
the CPUID [PST #12, see below] -- if the values used are similar to the ones
Windows XP uses. But this might be risky!!!

AFAIK, Dave Jones will add support to override the BIOS-provided tables.

Can you also mail the output of dmidecode, and the model of the laptop.
This is a 'beat up BIOS vendor' case, which AMD are actively trying to do.
I'll forward the info on to the right people..

Looks fine. I'll apply it when I get back from KS/OLS.

There's been some sysfs discussion with Pat in the last few days
(not specifically cpufreq related, but its going to become easier
to add this aparently..).

Yes that patch would IMHO point users with broken BIOS tables in the right
direction.

I think you know a bit more about these matters than me, so please allow me this
question:
How much risk do you think that would be (with the usual 'you are not responible
for any damages' stuff as usual) to just use that entry? At with the performance
governour it is exactly the same as displayed as currently by x86info so that
shouldn't be a problem. Do you think that lower frequencies and voltages can
kill the processor? [I can cope with instabilities]
Thank you for your help.

You are not likely to kill cpu (BTDT).

Hardware that lets software kill it deserved that.

Don't touch the Motorola 56xxx DSP, then. There are several
"insane instructions" that will smoke the device (programming
a pin for both input and output at the same time). There are
many other chips, often used on Motherboards, that have
programmable pins (even the AMD SC520)... These can be destroyed
by software.
Also, the bits for setting the power supply voltages to be
applied to your CPU are available in I/O space on many motherboards.
Try your 2.5 volt CPU on 5.0 volts. It will melt the solder that
holds the socket to the board!
Cheers,

Well, if motorola was so stupid that you can kill it by mistake... I
don't want to touch _that_.

On mainboards I saw it was in 'reasonable' range. I trust it not to
melt cpu before thermal diode does its job.
AMD's PowerNow at least will not let you overclock and/or
overvoltage. You are free to undervoltage, but that's crash-only.
Its true that HP Omnibook xe3 probably can be damaged, provided that
its CPU fan fails and there's just enough airflow to keep thermal
protection from kicking in. Its harddrive overheats in such case.
I guess that's uncommon enough.

I really can't answer on that as I do neither know the hardware nor the BIOS
implementation well enough. Sorry.
BTW, it's no surprise that the x86info and cpufreq output are the same --
they use the same code. It'd be more interesting if Window$ uses the same
values [just mentioning it as you said PowerNow works on it, so....]
