Forum member jakfish is currently testing with one of the Celeron-powered Eee models, but we can't test CPU control of Atom CPU's.
Are there any Eee-Atom owners who are prepared to do some testing?
Here's what I need:
In Puppy 4.3 with the 2.6.30.5 kernel, first run "lsmod" to check that the new "eeepc-laptop" module has automatically loaded.
If it's listed, great. If not, load it manually -
Code: Select all
modprobe eeepc-laptop
Code: Select all
cat /sys/devices/platform/eeepc/cpufv
770 powersave
769 normal
768 performance
The default value will probably be "769" ... but when running on battery the system might be smart enough (?) to be "770".
Now see if you can force the CPU FSB to one of the other modes -
Code: Select all
echo x > /sys/devices/platform/eeepc/cpufv
2 powersave (FSB 100MHz)
1 normal (FSB 133MHz)
0 performance (FSB 140MHz)
Each time check for success with the first command -
Code: Select all
cat /sys/devices/platform/eeepc/cpufv
Apparently Celeron-based Eee's need to use the old process involving the third-party "eee" kernel module ...
but Celeron users could certainly try this new process. The result is likely to be no worse than lack of success, and in a worst case situation where a Celeron unit might react badly and start to get warm, just shut down.
