cvm

h1ro · 03-30-2013, 05:41 PM

So, finally got around to install all the hacks yet again - I always lose the usbnetwork and such additions because of the stupid forced updates and lost motivation to do this stupid task of putting all these .update files there again.
Anyways, now I did it once again and looked into top and I saw:

1377 root 20 0 165m 63m 16m S 9.7 25.4 3:43.51 cvm

This is ridiculous, over 10% cpu and lots of RAM usage while I'm doing *nothing*. This can't be good for battery life. Is this normal or am I doing something stupid? Do we have to accept this?

cvm runs the guts of the Amazon stuff.

The majority of that footprint will be the loaded amazon bits and bats. Perhaps the %age is a background task such as indexing, I'm vague on the details not having a PW but that is my suspicion.

So normal? Yes,

Good? "I got nothing"

So why don't you install KUAL and the KUAL function buttons that block unwanted updates?

But I can understand your feelings about "the stupid task of putting all these update files" on the machine.
We sometimes get tired of creating all of these stupid update files for people.

hold on there, partner! it is VERY much appreciated!

Good news: it was not normal. Today I looked again, I had rebooted in the meantime, and cvm mostly does nothing when I'm doing nothing.
But then when I next touched it later and started KUAL again the kindle rebooted. I would like syslog, netconsole,... What causes such reboot? OOM? I would like to know what exactly fucked it up, and so on...

I had the kindle running all night, logged into my irssi screen and battery is still quite full. I only disabled the light. I will time how long it will hold out.

BTW having IRC on the kindle is awesome.

Personally, as a lunix guy I find it hard to start using this thing and developing properly with all the important info spread in super long threads. But I've been trying to find out, been reading for days and days now. Sometimes with some week of pause though.

twobob · 03-31-2013, 06:21 PM

so... look in the logs then... the reboot was probably the memory capped limit.. check the upstart configs.

you can always just restart cvm if it plays up again.

Welcome to the New World, and all that. Forums are so much better than mailing lists! You can't filter or change the user interface or score or... but you can have animated smileys!

(Bah. I don't understand it either.)

There's an easy way to get rid of cvm in case you don't want to run any amazon stuff. I'm only testing koreader right now, so now I don't need amazon to waste my precious CPU or RAM.

logged in via ssh you run:

stop x
sleep 5
/mnt/us/koreader/koreader.sh /mnt/us/documents

There's still strange network activity, some kind of ping i guess.

KUAL + KUAL firewall will deal with that network activity.

h1ro · 04-02-2013, 06:37 AM

you can stop more stuff, so the processes don't consume CPU:

stop framework
stop x
stop otaupd
stop phd
stop tmd
stop lipcd
sleep 5
/mnt/us/koreader/koreader.sh /mnt/us/documents &

I get absolutely no outgoing connection whatsoever now.

You should still firewall your device.

Network services that require changes in the firewall rules are only supported with the KUAL firewall infrastructure.

If totally against KUAL - just pull the details out of the firewall script and run it by hand.

h1ro · 04-02-2013, 07:25 AM

Actually I do run a firewall, on my router. I'm sure this advice is still important for other people trying this out though.
