I have Acer Aspire 1357LMi laptop with AMD Athlon XP 3000+ and of course
cpufreq don't work
powernow: AMD K7 CPU detected.
powernow: PowerNOW! Technology present. Can scale: frequency and voltage.
powernow: Found PSB header at c00f06f0
powernow: Table version: 0x12
powernow: Flags: 0x0 (Mobile voltage regulator)
powernow: Settling Time: 100 microseconds.
powernow: Has 8 PST tables. (Only dumping ones relevant to this CPU).
powernow: No PST tables match this cpuid (0x7a0)
powernow: This is indicative of a broken BIOS.
powernow: See
http://www.codemonkey.org.uk/projects/cpufreq/powernow-k7.shtml
I've read many interesting threads here and I saw the patch which use
acpi which would solve my problem I think. If you need volunteer to test
it on an acer laptop I think I can.
I tried to flash the bios with the one on acer website but it seems that
it is older than the one I already have, and it doesn't solve the
problem anyway.
I managed to run at 2200 Mhz max and 800Mhz min under windows

Could you please try latest cpufreq? it's at
http://www.codemonkey.org.uk/projects/bitkeeper/cpufreq/
with CONFIG_ACPI_PROCESSOR=YES ?
I would like also that you test dump_psb.c
wget http://poup.poupinou.org/cpufreq/powernow-k7/dump_psb.c
gcc -O2 -Wall dump_psb.c -o dump_psb
sudo ./dump_psb 9
in order to check if that model actually do have more PSTs.

You're running with Speedstep,
You don't have DMA enabled for your hard disk (see hdparm),
Incorrect TSC synchronization on an SMP system (see dmesg).

Ok. I expected that BIOS will put the frequency at max at POST stage.
That is not true for your laptop indeed. Can you try that patch:

Yes, when I bought the laptop the speed was always 800Mhz without any
powernow driver in windows. Maybe the bios here is useful :
ftp://ftp.support.acer-euro.com/notebook/aspire_1350/bios/zp13a18.zip
the changelog in the zip talks about a low speed patch

You're running with Speedstep,
You don't have DMA enabled for your hard disk (see hdparm),
Incorrect TSC synchronization on an SMP system (see dmesg).
Falling back to a sane timesource now.

I don't know if that bios will help you. Latest bios for Acer Aspire
1310 do give weird result both with PSB/PST method and ACPI (ACPI is
less buggy)..

Try with UP kernel. At that time, cpufreq break TSC timer on SMP
kernels. Or alternatively use the ACPI-timer.

Thank you for your support, Now all is fine

Why is TSC timer on SMP broken, in your opinion? AFAICS, the problem seen on
this machine is caused because of actual cpu frequency != frequency the
cpufreq core thinks the CPU is in.

It's broken if CONFIG_SMP because set_cyc2ns_scale() is not called
in the time_notifer() in timer_tsc.c (and anyway cpu_khz can't be
scaled in an easy fashion if SMP).
Therefore, cyc2ns_scale is not updated, and cycles_2_ns() will give
false values.

Indeed. Will try to prepare a patch to make cycles_2_ns handle different
CPU speeds correctly -- it's needed for different-speed-SMP as well.[*]

The problem is that AMD64 (and opterons) processors do have expected
behaviour, that is if you change the frequency, TSC clock will change
as well, and there are SMP capable processors that are planed IIRC.
Also, I think TSC timer will not work properly if powernow-k8 on such
system (each processors would have different TSC frequencies),
unless heavy changes to the TSC timer code. I'm not sure if making
it work does really matter, there is other good timers (like ACPI-timer)
after all.

Even though most, if not all, AMD64 processors have HPET-timers on the
motherboards, there's still much tsc interaction going on :-(. Will take a
look at it soon.
