huge memory usage


just built disko and morphine for an embedded device, with roughly 100MB ram available.

Turns out morphine is using >100MB, which is probably the reason why it doesn't do much (apart from showing the Morphine splash screen on the framebuffer)

Tried to run disko tutorial 01 instead, just a hello world message, and even that used 118MB of ram.

Didn't you claim that disko is a framework for embedded devices?

hi zzy,

is tested the memory usage of Morphine.TV and of the Disko tutorial 01 and i can't verify your results.

Tutorial 01:
I started the tutorial 01 and if you compiled Disko with Alsa, Xine and libcrypt support you will see, that all dependencies are loaded. In my case 10 Mb are used by the tutorial and 45 Mb are used by dependent libraries. Please rebuild Disko and try to disable all libs which are not required.

Morphine.TV:
Morphine.TV is a media center showcase and was designed to run on typical set-top boxes. We ported and tested Morphine.TV on different devices which had minimum 256 MB RAM. We need a lot of memory for example to manage the media meta data, like EPG information, weather information, etc.

Please restart your Tutorial 01 test and maybe you can send a short memory report (for example a pmap report).

regards

Guido

Hi Guido,

this is a pmap dump of ./01, most memory is consumed by anon , not sure how to tell which part is to blame?

hi zzy,

we have no reasonable explanation for the 8188 anon blocks. These seem to consume most of the memory. Could you tell us the DirectFB version you are using, and post us the contents of the diskorc / morphinerc?

have fun
Stefan

hi zzy,

we can reproduce the problem and we're going to analyse it. it seems that we have different results with different DirectFB versions.

This will take a while so please be patient and stay tuned. We will post the results as soon as possible.

regards

ok, good news that at least it's reproducable.
In the meantime I could try to move to a different directfb version, do you have a prefered version?
