portable >> HELP: pentium-m laptop and speedstep problem

by whatdoineed2do » Fri, 08 Apr 2005 08:19:10 GMT

hi,

i have a acer travelmate 8005 which has a pentium-m centrino with
speedstep. however, using 2.6.11, i am unable to load the
speedstep-centrino kernel module as it complains that there is no such
device.

i have read in many other places whereby ppl with the same laptop have
got this to work. is there something wrong with my kernel config?

thanks

it appears that this machine does all scaling with the acpi_cpufreq
module (CONFIG_X86_ACPI_CPUFREQ)

Yes I do. This is my configuration now:

/boot/loader.conf:
cpufreq="YES

/etc/rc.conf:
powerd_enable="YES"
powerd_flags="-a maximum -b adaptive -n adaptive -v"

But look at this (that's all I get, all the time):
idle time > 90%, decreasing clock speed from 1729 MHz to 1729 MHz

sysctl dev.cpu.0.freq_leves offers a wide array of frequencies
ranging from 1729 MHz down to 99 MHz. What's wrong? Why doesn't
it decrease the clock speed below 1729 Mhz?

-b minimum works as expected, setting the clock speed to 99 MHz.

3. Enhanced SpeedStep on Pentium M 

I'm trying to save some battery on my laptop, so I want to
enable EST on FreeBSD 6.0, but I don't know how to do it.

dmesg says:
Features2=0x180<EST,TM2>

I have done some reading, but I'm very confused.

I've tried putting this in /boot/loader.conf:
cpufreq_load="YES"

And this in /etc/rc.conf:
est_enable="YES"
estctrl_enable="YES"

Now dmesg also says:
est0: <Enhanced SpeedStep Frequency Control> on cpu0
p4tcc0: <CPU Frequency Thermal Control> on cpu0

Is that it, and how am I to tell if it's working?
