02:46 dung_ jumbo frames :)

02:49 dung bigger, faster. jumbo!

03:04 dung take a seat on my bench

03:04 dun 03:04 * dung let his CuBox calculate

03:07 dung "papa don't, papa don't make no mess!"

03:13 Punk-le 03:13 * Punk-ley thinks dung has lost his mind :)

03:13 dung ?

03:14 Punk-ley just what you are typing :)

03:21 dung from am song, listening

03:21 Punk-ley ah

03:23 Punk-ley i was at a gaming expo on the weekend, I now have Gangnam Style, Call Me Maybe and What Makes You Beautiful just on loop in my head. I blame Just Dance 4

03:39 dung is anyone interested in downloading toolchains?

03:39 dung uclibc from cubox

03:41 dung should it be cubox only? how caompatible can it be? how compatible can be a kernel on arm in general?

03:42 dung i remember the u-boot driver file

03:43 dung should the binaries be compatible or optimized for cubox?

03:47 dung or both :)

03:48 dung all is not enough

03:48 dung less is more

03:48 dung my cat ate my mouse :)

03:51 dung high end (never ending (tcpdump (c)))

03:56 dung It should be clearer that in software less is more.

06:09 neofob @ dung: yeah jumbo frame is hot! ;)

06:56 dung Jumbo :)

07:10 dung @Thirsty_away - would you patch aufs?

10:57 Thirsty_Away dung: I can make an update on the kernel tree

10:58 Thirsty I like to include CEC patch and maybe the cpuscaler patch

10:59 rabeeh Thirsty: what is the cpuscaler patch?

10:59 rabeeh any one tested that?

10:59 rabeeh there is 800/400 MHz available in 2.6.32.9; but Dove is much more complex than Kirkwood in CPU scaling.

11:00 Thirsty I saw a post on the forum. It was a kirkwood patch

11:01 Thirsty http://www.solid-run.com/phpbb/viewtopic.php?f=9&t=851

11:02 Thirsty I didn't look in to it.

11:02 Thirsty It sounds usefull if it works.

11:03 Thirsty Jumbo frame was also a request to add on the kernel.

11:05 Thirsty I don't use my Cubox not that much any more.

11:06 Thirsty I am builing a network in my house so I can use the Cubox as a media player with CEC in my bedroom.

11:09 Flooo hi =)

11:14 Thirsty hi

11:29 Flooo how r u?

11:30 Thirsty fine and you?

11:31 Flooo fine, too. thx

11:32 Flooo atm I'm running your kernel. Did u configure it with hard float?

11:33 Thirsty yes, I compiled and running it on a debian wheezy hardfp distro.

11:37 Flooo is it possible to have a kernel 'the debian way'? (with initrd image). is it recommended without? any disadvantages?

11:38 Thirsty I have no idea.

11:39 Flooo ok :D thx anyway

11:39 Punkley_Chillin it should work with initrd

11:40 Punkley_Chillin what kernel version

11:40 Flooo I don't think kernel version will matter, will it?

11:40 Punkley_Chillin i had some issues with 3.4.5

11:40 Punkley_Chillin but 3.5.3 was ok

11:41 Flooo oh, ok

11:41 Punkley_Chillin galcore just played up for some..... unknown..... reason

11:42 Flooo how did u get it working? is there any page in the wiki?

11:43 Punkley_Chillin ah i should say i was using armel not armhf

11:43 Flooo could u please create one? or post in the forum?

11:43 Punkley_Chillin kernel?

11:44 Flooo kernel + initrd + uboot config

11:44 Flooo -kernel

11:44 Punkley_Chillin ok it is all there, we do need to make it neater

11:44 Punkley_Chillin kernel is here

11:44 Punkley_Chillin https://github.com/vDorst/linux/tree/CuBox-v3.5.3-Patched

11:45 Punkley_Chillin u will need to build it

11:45 Punkley_Chillin actually what distro are you using?

11:46 Flooo umm.. did u get what I wanted to?

11:46 Punkley_Chillin don't know what you mean?

11:47 Flooo my issue wasn't the kernel.. it's more about initrd and how to get it working with uboot

11:48 Punkley_Chillin ah

11:48 Punkley_Chillin easy

11:48 Punkley_Chillin in your boot.scr file

11:49 Punkley_Chillin under the line

11:49 Punkley_Chillin ext2load mmc 0:1 0x00200000 /boot/uImage

11:49 Punkley_Chillin add

11:49 Punkley_Chillin ext2load mmc 0:1 0x02000000 /boot/initrd

11:49 Punkley_Chillin then change the line

11:49 Punkley_Chillin bootm

11:49 Punkley_Chillin to

11:49 Punkley_Chillin bootm 0x00200000 0x02000000

11:49 Punkley_Chillin make sure the addresses are right (0x00200000 and 0x02000000)

11:50 Punkley_Chillin and the uimage of initrd is initrd

11:50 Punkley_Chillin you will have to convert the initrd to a uimage

11:50 Punkley_Chillin mkimage -A arm -O linux -T ramdisk -C gzip -n "Debian netboot" -d initrdimage initrd

11:51 Punkley_Chillin i think I just confused myself hmmm :)

11:51 Flooo you're right there.. looks easy

11:51 Punkley_Chillin yer worse description ever

11:51 Punkley_Chillin hang 5

11:51 Flooo I'll test it! thank u!

11:52 Punkley_Chillin don't forget you can't just edit your boot.scr file

11:52 Punkley_Chillin need to rebuild it.

11:53 Punkley_Chillin if I completely confused you (which I might have)

11:53 Punkley_Chillin let me know Ill put it somewhere make sure it makes more sense.

11:54 Flooo no. I think I got it =)

11:54 Flooo mabe make a wiki page?!

11:54 Flooo *maybe create

11:54 Punkley_Chillin yer, looks at dotarray :)

11:55 dotarray i'll add it to the list :)

11:55 Flooo thx to both of u

11:58 Flooo is the size of uImage limited?

11:59 Flooo btw

11:59 Punkley_Chillin not sure to be honest

12:01 Flooo the two addresses u gave r in ram I guess?!

12:01 Punkley_Chillin yer

12:03 Punkley_Chillin holiday in isreal today

12:03 Punkley_Chillin everybody out drinking :)

12:07 Flooo yay! enjoy it! =)

12:08 Flooo 0x02000000-0x00200000 = 31457280 Byte = 31457280 / 1024 ^ 2 = 30MB

12:09 dotarray Flooo - unfortunately, Punkley_Chillin and I are in Australia, where it is not a holiday :(

12:09 Flooo oh sry :( shame on me

12:09 dotarray not a problem!

12:09 Flooo theres 30MB space between these addresses.. is that right?

12:10 Punkley_Chillin something like that, I did look it up however I don't remember now (just know it works)

12:10 Flooo :D

12:12 Flooo means: uImage must be smaller than 30MB or initrd will overwrite uImage

12:12 Flooo thats far from possible

14:36 dbsx Floo: Debian kernels "the debian way" whilst they are ok on small devices, mean a slower boot. Most small boxes seem to just use uImage. IMHO, With a constrained set of drivers that are used at boot time there is no need for getting into the debian initrd hassles.

14:46 Punkley_Chillin I agree, unless you need an initrd don't use one.

14:46 Punkley_Chillin I unfortuatly need one :(

15:04 dung I stay in initramfs. Only hotplug isn't working as with udev.

16:17 mUniKeS sorry, somebody knows a manual to how to configure cubox with debian armhf and xbmc?

16:40 dv505 mUniKeS: you can't, for now. the codecs are not compatible with armhf

16:42 mUniKeS ok, thanks

16:43 dv505 I've been trying to build a debian armel now, but no success with that yet

16:43 dv505 mainly because I'm not that good in compiling stuff

16:44 dv505 mUniKeS: how far did you come with building xbmc. I could give you a few pointers to start

16:48 mUniKeS I compiled all

17:45 mUniKeS dv505, I compiled the XBMC (crosscompile), I compiled the kernel with dove support (crosscompile), but the XBMC is dark, when start

17:46 mUniKeS I have the new links of libEGL.so and libGLESv2.so.2, marvell-libglx

17:47 N30N mUniKeS: What problems have you get with it now?

17:48 mUniKeS N30N, the XBMC is dark

17:49 N30N xbmc got gles enabled?

17:49 N30N GLES

17:50 mUniKeS yes configure --enable-gles

17:50 mUniKeS the log says (.xbmc/temp/xbmc.log) 18:15:02 T:3032170496 DEBUG: GLES: Extension Support Test - GL_NVX_gpu_memory_info NO

17:52 N30N Hmmm... not come across that error myself.

17:52 N30N glxgear work ok?

17:52 N30N glxgears*

17:55 mUniKeS no es2gears_x11

18:11 mUniKeS sorry have only this warning: EGL: Same window as before, refreshing context

18:35 mUniKeS bye

21:18 jnettlet rabeeh, my KMS changes are pushed anywhere yet. I am still sorting out HDMI for the MMP2/MMP3. Marvell is currently supporting this through a binary UIO driver. I am trying to get a proper OSS driver implemented for it.

21:19 jnettlet Here is the commit for write coalescing in the kernel that I finally merged. http://dev.laptop.org/git/olpc-kernel/commit/?h=arm-3.0-wip&id=a8137cd10a1ab06650a337c85b001cb4dba3a56d and the one after it has the relevant benchmarking improvements. http://dev.laptop.org/git/olpc-kernel/commit/?h=arm-3.0-wip&id=f9d35acbe063de67747826ddba2bcaa692757e1b
