Hi,
I've tested the new eee-cpucontrol-0.3.pet.
I can't see any difference to old .pet (meaning the Celeron part). To be exactly, /var/log/eee-fan.log appeard with the first run. The rest seems to be the same:
After reboot it starts with the CPU speed 900 MHz, no matter I selected before.
Changing fan speed takes only effect after reboot, by temp < min. than reaching temp.max. or by running pinstall.sh manually.

Ok, Thanks for reports.
I think then I will change the gui button to exit.
It's time for a script in /root/Startup to execute the last remembered state..
Cheers

A word of caution guys;
I wouldn't assume that rhadon's CPU speed is actually 900 MHz. The gui might be lying!
Rolf, immediately after booting, I suggest you run this command -
If you see "100 24 1" then yes, your CPU speed is 900MHz.
But if you see "70 24 1" then your CPU speed is 630MHz.
Now run the gui to check what CPU speed it reports.

Yes, that's what the Ubuntu Eee packages do ... but it's not necessarily the best approach.
Having your Eee boot up with the default CPU speed (as defined by ASUS) is not a bad thing.

Hmmmmm...
I have had an error on reboot and can't fix it. (701SD)
When I "cat /proc/eee/fsb" it returns "30 15 0" .. very strange, and I can't get away from it... even using small increments, no good. I can do "echo 30 15 1 > /proc/eee/fsb" and that's about it. (I understand the 3rd field is for voltage). If I change the 15 for 24 the machine crashes, if I increase 30 to 35 the machine crashes. I can't find any pertinent info either.
A small script in /root/Startup or even a line in etc/rc.d/rc.local (I favour the script) could tell the gui to be in default mode on boot. But.. what is the default on an Atom? I expect "Normal" but I can't assume this.
I have the fan showing up in 'Pwidgets', but what do we want to display? I would favour "rpm" (cat /proc/eee/fan_rpm). I can also mod it for plain 'conky' too. In fact I can make a "eee widget" with fsb info too. Ideas anyone?

Rolf, are you saying that your CPU is truly running at 900MHz at bootup, as reported by
?
Or that the CPU is running at its default 630MHz, but the gui reports 900MHz?

As dawnsboy reported on page 4 of this thread, there's an updated version of the Celeron processor which runs at a higher FSB speed of 400MHz.
I think that the "eee" kernel module only supports the older Celerons with 70/100MHz FSB speed. So reading/writing /proc/eee/fsb will only work with these older Celerons.
It appears that new Celerons work by reading/writing to /sys/devices/platform/eeepc/cpufv
same as Atom CPU's.
01micko, does your "cat /proc/cpuinfo" report "... Celeron M 353 ..."?
I can only search the web for this information, but it seems that "353" indicates the new Celeron.
If true, your post-install script will need to enable the eeecontrol-atom script for Atoms and "353" Celerons, and enable the eeecontrol-cel only for non-"353" Celerons.

I can't see it... Perhaps rhadon could post the out put of "cat /proc/cpuinfo" so I can compare and draft a reasonable command to differentiate the two. Perhaps other Celeron owners could try this too.
Cheers
(I'm posting from a different install now, until I sort out my little issue, It doesn't seem to affect the speed of the machine at all. I will have to do some benchmarking with the Atom commands on this machine to see if there are differences. The alternative is to offer the 2 separate pets triggered by the same command. That command will just work differently)

Oh dear.
It seems that the appropriate FSB adjustment command for various Eee models with Celerons cannot easily be determined.
I now suspect that different bios versions may have a major impact on this issue.

details of Atom settings Subject description: How do I get more than the mode for Atom? |
|
I'm also wondering exactly what change is taking place on the Atom processor when we change the settings. When I put it in 'powersave' mode, I get the number 770 back to confirm this, as I posted above. It is possible to change both fsb frequency and multiplier to get essentially the same processor speed, at least for programs small enough to stay in cache.
I'm familiar with tweaking fsb, multiplier and voltage on older processors, though I admit the codes for doing so are not things I keep in my head. I got this information from overclockers although I was mainly interested in underclocking. I haven't noticed people overclocking netbooks. It sounds like a bad idea.
There is no /proc/eee directory for my Atom installation. Is there another way to discover the details of processor clock, voltage and fsb setting?
Off-topic:
My (prehistoric) memory brought forth a rhyme from the cold war era.

Hi prehistoric
You can poke around in /sys/devices/platform/eepc directory and see what you come up with. For monitoring look in /sys/class/hwmon/hwmon0.
Cheers

The /proc/eee directory should appear once you have installed and loaded the "eee" kernel module, from -
http://www.murga-linux.com/puppy/viewtopic.php?p=346452#346452
... but for Atom-based Eee's this is only useful for fanspeed control.
For CPU FSB control Atom models require the eeepc-laptop module, which creates files in /sys/devices/platform/eeepc
as explained on the first page of this thread.

@tempestuous
The chipset in the Eeepc 701SD is in fact the Intel Celeron M 353. The cpu on these models defaults to 900MHz. The 701SD cannot be "overclocked" using the methods and software available to users of the older 701's however it appears that the 701SD outperforms the 701 out of the box anyway.
Users on the forum at eeeuser.com report that they have been unsuccessful in overclocking it with the exception of those who have tried the Super Hybrid Engine (701SD apparently came with it installed) report being able to adjust clock speeds to 630MHz (underclock), 900MHz (default) and 960MHz (overclock).

kernel modules and stack trace on boot |
|
@tempestuous,
O.K., bear with me here. I've been through the sequence of installs described in that post of yours before. I got a fault and stack trace during boot. Just tried again. Attached are the boot kernel and boot sysinit logs from the boot following that. The fan control script complains that the proc/eee directory does not exist.
One tantalizing note is the statement about the number of options for CPU throttling. Quote: | ACPI: Processor [P001] (supports 8 throttling states) |
Description |
bootkernel.log and bootsysinit.log gzipped together after installing eee-0.2-k2.6.30.5.pet, xbacklite-1.1.pet and acpid-1.0.10-Eee.pet and rebooting on an ASUS eeePC 900A with 1.6 GHz Atom N270 processor
