[Sit Heel Speak]

I don't have an eee, but am tinkering with a Mini-9 with N270 Atom. Found something yesterday, which may be of interest:

At http://cvs.fedora.redhat.com/viewvc/F-11/mingw32-gcc/

file: gcc-atom.patch

A patch to enable gcc to use -march=atom -mtune=atom

Written by a trio of Intel engineers in merrie olde Cathay.

There is a large hunk in the middle --maybe a thousand lines, text-search the patch on "i386.c" (in Geany) to find the beginning of the vast sea of green-- which will not apply cleanly to the gcc 4.4.1 source if you use the patch command. Perhaps because too big?

So I have applied this big hunk by hand-editing i386.c, in the gcc-4.4.1 source. Then, after deleting this large hunk from the patch, the rest of it applies cleanly to the rest of the gcc source.

Here is the gcc 4.4.1 i386.c, patched by hand, in case anyone with an Atom feels 90% as ambitious as yours truly. I plan to compile a kernel and OpenBox using the patched gcc, in the next few days, in my project to custom-fit the Mini-9 with a Puppy. If anyone comes up with meebo-less Skype for the Atom, please convey it to me.

Well the question now becomes: do you want a manual CPU FSB control,
or do you want an automatic control, so that the CPU FSB goes into Powersave mode whenever the laptop is on batteries?

Now moving on to the fan.
I have already compiled the third-party "eee" kernel module for this purpose, and jakfish reports that it works OK, but it would probably be better to use the fan control functions of the new "eeepc-laptop" module now that Puppy 4.3 contains this module.

Some testing is needed -
normally the fan speed is controlled by bios. Running this command should set the fan control to manual -

Hello tempestuous and all else.

The fan commands all work as expected for me on the 701sd. However, the temperature command does not work for me, I get the same result as Mike above.

I normally use conky/Pwidgets to monitor temperature but there is another command I found that returns the correct temperature.

Sorry to be late - watching Geelong win again.
pup430-small 2.6.30.5 eeepc901 (atom 1.6):
changed mode from performance to normal; temp 51C using 01micko method; fan matching cpu mode automatically sounds good.
also changed fan to manual - speed 123 then 167 then 123 - could hear speed changes, but no temp change (51C).

Thanks for the results. For the eeepc-laptop module to read temperature it appears that the "lm-sensors" utilities might be needed ... or maybe the i2c-dev kernel module ... but it's getting too difficult.
Dougal's fan control script is based on the "eee" kernel module, so it makes sense to use that module, even though it needs to be installed separately.
I should have a package available shortly.

Hi,

with EeePc900 (Celeron, 900Mhz), frugal, booting from sd-card:

fan works as expected, temperature depending from fan speed during test 49C -56C.

No luck with cpu speed.
Everytime the answer is 512, no matter the question was (sorry meaning no matter I use 0, 1 or 2 from console or the GUI from 01micko. If I use GUI and choose "Normal", cursor freezes, can't kill X and must poweroff.

Although the thread is titled "Eee Atom CPU control - testing" I hope this is of interest.

Edit: For displaying temperature I use the command from 01micko

Here is a rough gtkdialog gui for CPU/fan control. I intend that it will be launched by the Fn+F6 hotkey combination.
For testing purposes you can launch it from the terminal -
