Now, let's talk about the cpufreq stuff :)
cpufrequtils 005: cpufreq-info (C) Dominik Brodowski 2004-2006
Report errors and bugs to cpufreq@xxxxxxxxxxxxxxx, please.
analyzing CPU 0:
driver: loongson2f
CPUs which need to switch frequency at the same time: 0
hardware limits: 199 MHz - 797 MHz
available frequency steps: 199 MHz, 299 MHz, 398 MHz, 498 MHz, 598
MHz, 697 MHz, 797 MHz
available cpufreq governors: conservative, ondemand, userspace,
powersave, performance
current policy: frequency should be within 199 MHz and 797 MHz.
The governor "ondemand" may decide which speed to use
within this range.
current CPU frequency is 797 MHz (asserted by call to hardware).
cpufreq stats: 199 MHz:0.00%, 299 MHz:0.00%, 398 MHz:0.00%, 498
MHz:0.00%, 598 MHz:0.00%, 697 MHz:0.00%, 797 MHz:100.00%
It seems to be working but it's weird. When I start X and gnome
(cpufreq applet). I can see
that's the system is using the ondemand performance but is stuck at
797 Mhz if I don't do anything.
If i start working (yeah it's happening sometimes), the frequency is
moving from 199Mhz to 797Mhz.
The other thing which is weird is that I don't have this problem with
the Loonux stock kernel.
Hello,
I've switched from the ondemand governor to the conservative one and
it seems
to be working properly.
Yes, the conservative governor is better than the ondemand.
I have also noticed that the fans seems to be running at full speed
all the time.
Any comment, on this issue ?
we test that it only save power about 1~2w when the cpufreq is min.
So the temperature will be reduced a little.
when the temp is the some section,
eg. the 60°C and 65°C are the same section when the section is 60°C~70°C，
the speed of fans will be the same.
Is there a way to query the sensors ?
Please insmod ec_ftd which is one of the ec modules.
And then type "cat /proc/ft" , the output: "1.31 0x01 4705 0x00 56"
the 4705 means the speed of fans, 56 stands for the temperature
