Title: Problem With Kapm-idled
Post by: xamindar on March 04, 2006, 07:48:32 pm

I notice my zaurus seems a bit sluggish so I opened up top and kapm-idled is using too much cpu.  What is wrong with it?

I've noticed that too. If I understand correctly, kpam-ilded is a part of the 2.4 kernel & we can't be rid of it. Others might pipe in that have a better understanding.

And even if you could kill it, your Z would probably freeze & require a reboot. Like I said, it's a necessary part of a 2.4 kernel based ROM. The only way to be rid of it (that I know of) is to upgrade to a ROM that uses a newer kernel (like 2.6). I'm not to familiar with the 3100's; I know that there's currently no 2.6 support for my 5600. I see your using cacko. Why don't see if they have a 2.6 kernel based ROM? Or check out OZ? HTH

Here is just one of the top hits you get when seaching google for "kapm-idled"

"Symptom: your system is doing nothing, and yet any CPU monitor program (top, gtop, pks, etc.) shows that the CPU is busy around 70% of the time with a process called kapm-idled

This is no problem. kapm-idled is an "idle" process: a process that only operates when other processes don't. The moment anything else in the system will need the CPU, apmm-idled will leave the CPU.
So you don't need to do anything.

kapm-idled is only used in kernels of version 2.4 and upwards. Most recent distros (since around spring 2001) use kernel 2.4 by default. To see the kernel version that you currently run, you can use the command 'uname -r'

This has been addressed numerous times on the forums, the onlyu way to get rid of kapm-idled is to stop your kernel (ie shutdown the zaurus)

If you would prefer not to see it in top, then you will need to find an updated version of top that "knows" about the 2.4 kernel changes

oh ok, the slowness I was having must have been caused by something else.  Thanks for the info.

what is idled?

it's a very low priority process which runs when nothing else does, and runs the IDLE instruction, which tells the processor (CPU) that it can shutdown certain functions, and thus sames power.

if you want your Z to consume lots of power, why not download the distributed.net keycracking program dnetc and watch your battery run dry really fast!
