| koalo | hi | 00:55 |
|---|---|---|
| koalo | i tried to build a rootfs for qemu but everytime i get a Kernel panic - not syncing: Attempted to kill init! | 00:59 |
| persia | How are you trying to build the rootfs? | 01:02 |
| koalo | like in https://wiki.ubuntu.com/ARM/RootfsFromScratch | 01:03 |
| koalo | sudo rootstock --fqdn ubuntu --login ubuntu --password ubuntu | 01:04 |
| koalo | and then mkdir /tmp/arm | 01:05 |
| koalo | sudo mount -o loop /tmp/arm.img /tmp/arm | 01:05 |
| koalo | cd /tmp/arm | 01:05 |
| koalo | sudo tar xzvf ../qemu-arm-rootfs.tgz | 01:05 |
| koalo | cd .. | 01:05 |
| koalo | sudo umount /tmp/arm | 01:05 |
| koalo | rm /tmp/arm | 01:05 |
| koalo | qemu with | 01:06 |
| koalo | sudo qemu-system-arm -M versatilepb -kernel /tmp/vmlinuz-2.6.28-versatile -cpu arm926 -hda /tmp/arm.img -m 256M -append "root=/dev/sda mem=256M" | 01:06 |
| persia | That certainly looks right. | 01:08 |
| * persia tries | 01:08 | |
| koalo | oh and qemu-img create arm.img 1G | 01:11 |
| koalo | sudo mkfs.ext2 -F arm.img | 01:11 |
| persia | I seem to be bumping into a bug that prevents rootstock from running at all today. Sorry. | 01:11 |
| persia | Someone else may have to help. | 01:11 |
| koalo | thanks anyway! | 01:13 |
| koalo | the rootfs from http://people.canonical.com/~ogra/arm/qemu/qemu-arm-rootfs.tgz works.... | 01:22 |
| koalo | i give up for today | 01:35 |
| koalo | bye | 01:35 |
| DanaG | interesting... bootchart doesn't do anything on arm. | 06:30 |
| DanaG | Nor does ureadahead. | 06:33 |
| DanaG | Probably doesn't need to do anything, though. | 06:33 |
| Martyn | wait, ureadahead should work! | 06:50 |
| Martyn | it should be prepopulating the cache | 06:50 |
| Martyn | Did we forget to add the patch into the arm branch of the kernel? | 06:51 |
| DanaG | Then again, my ureadahead doesn't work on my host amd64 system, either... terminates with status 4. | 06:56 |
| DanaG | =รพ | 06:56 |
| DanaG | So maybe I'm just unlucky. | 06:56 |
| DanaG | hmm, /var/lib/ureadahead/ has just debugfs; no "pack". | 06:56 |
| DanaG | Also, my thing isn't using an initramfs, and update-initramfs does nothing. | 06:56 |
| DanaG | http://pastebin.com/fc125c14 | 06:58 |
| DanaG | that is: bash -x `which update-initramfs` -u -k all | 06:59 |
| Martyn | Yeah, I'm only just starting to work with initramfs/initrd for arm server | 07:00 |
| Martyn | it will be a while before I walk the entire chain | 07:00 |
| DanaG | Plus, initramfs needs u-boot to know what to do with it, also. | 07:01 |
| DanaG | As it is, the kernel has to come from elsewhere -- I went here: http://rcn-ee.net/deb/kernel/beagle/ | 07:01 |
| DanaG | Are there any plans to have standard in-repo kernels for various boards? | 07:07 |
| Martyn | no | 07:10 |
| Martyn | at least, from what I saw, only the supported processors on their test platforms for now | 07:10 |
| Martyn | Marvell Dove | 07:10 |
| Martyn | etc | 07:10 |
| Martyn | etc | 07:10 |

| ogra | does anyone have additional ideas what should be on the rootstock gui for its first iteration ? http://people.canonical.com/~ogra/rootstock-gui.png | 13:01 |
| ogra | asac, ^^^ ? | 13:01 |
| asac | ogra: make the image size typable ;) | 13:01 |
| ogra | pfft | 13:01 |
| asac | ogra: whats the "run tasksel" button | 13:02 |
| ogra | well, beyond that, any options you would like to see ? | 13:02 |
| asac | if you click there it instantly runs tasksel? | 13:02 |
| ogra | it fires up the tasksel gui | 13:02 |
| asac | so right when clicking? | 13:02 |
| ogra | http://people.canonical.com/~ogra/rootstock-tasksel.png | 13:03 |
| ogra | its a separate window | 13:03 |
| asac | k | 13:03 |
| ogra | asac, http://people.canonical.com/~ogra/rootstock-gui.png more happy with that ? | 14:45 |
| asac | ogra: can one type | 14:46 |
| ogra | (the file menu has a save profile/load profile as well) | 14:46 |
| ogra | indeed | 14:46 |
| ogra | well, you will, thats all mockup atm | 14:46 |
| asac | ogra: seed url doesnt work? | 15:04 |
| ogra | no, thats not in the script yet either | 15:04 |
| asac | kk | 15:04 |
| ogra | something for L+1 | 15:04 |
| asac | image size -> implies we create a real image now? | 15:05 |
| ogra | no, should i call it rootfs size rather ? | 15:05 |
| asac | rootfs max size | 15:05 |
| asac | ? | 15:05 |
| asac | why do we need that? cant we do an estimate? | 15:05 |
| ogra | its one point i would even like to automate, but that smells like a huge amount of code to compute it in advance | 15:06 |
| asac | guess not ;) | 15:06 |
| asac | right | 15:06 |
| ogra | also L+1 :) | 15:06 |
| asac | but cant we say: 4GB by default? | 15:06 |
| ogra | no, people that do ubuntu-minimal will only neeed 500MB | 15:06 |
| asac | but that space isnt wasted | 15:06 |
| ogra | i dont want to waste more diskspace than needed | 15:06 |
| asac | its just temporary right= | 15:06 |
| asac | ? | 15:07 |
| ogra | its used during build | 15:07 |
| asac | right | 15:07 |
| ogra | so your host definately needs that amount | 15:07 |
| asac | we can take as much as the file system has ;) | 15:07 |
| ogra | no, that would strictly bind to the filesystem | 15:07 |
| asac | run a check before build if /tmp partition has more than 4GB ... if so acquire it, other pop up a dialog and ask user to select a smaller guess ;) | 15:07 |
| ogra | i want to preserve the funstionallity that you can use the script without a FS | 15:07 |
| asac | without a fS? | 15:08 |
| asac | FS? | 15:08 |
| ogra | without a target partition | 15:08 |
| asac | how can a rootfs work without a filesystem? | 15:08 |
| ogra | the script should still go on to produce tarballs | 15:08 |
| asac | i dont think i understand you. keep the option ;) | 15:08 |
| ogra | as well as the gui ... | 15:08 |
| asac | i know | 15:08 |
| ogra | only if you fill in the bottom option to write to target partition we actually have a size | 15:09 |
| asac | i am saying. if your local /tmp partition has more than 4GB size, use that as image size | 15:09 |
| asac | otherwise ask :) | 15:09 |
| asac | but i see that its not accurate | 15:09 |
| asac | maybe "grow-on-demand"? | 15:09 |
| asac | guess thats harder | 15:09 |
| ogra | yes, thats quite hard the stages are to disconnected | 15:10 |
| ogra | i would go with a hard 4G for the gui ... | 15:10 |
| ogra | given that when you run the gui you really should make sure to have enough build space | 15:11 |
| asac | anyway. i think we should set the image size to a reasonable default and move it from the top | 15:11 |
| asac | i think i just care so much because i would expect the top most option to be quite important | 15:11 |
| ogra | the prob is what happens if a user is insane enough to pick kubuntu-debsktop, ubuntu-dekstop, xubuntu-desktop at the same time | 15:11 |
| asac | right | 15:11 |
| asac | lets move it down | 15:11 |
| asac | and use a reasonable default (e.g. 4 or 2 GB) | 15:12 |
| ogra | 4 then | 15:12 |
| ogra | thats definately safe for most operations | 15:12 |
| asac | also name it (build space) or something | 15:12 |
| ogra | with a minimal size coded in the spinbutton | 15:12 |
| ogra | i.e. 0.5 G | 15:12 |
| asac | i dont care about minimal size ;) | 15:13 |
| ogra | well, the actual build space is a bit more than the image size | 15:13 |
| asac | doesnt matter ;) ... name it: rootfs build area | 15:13 |
| ogra | (kernel Packages file etc... but that should be in the megabytes | 15:13 |
| ogra | ok | 15:13 |
| asac | what is in datei ? | 15:14 |
| asac | in the menu? | 15:14 |
| ogra | load profile/save profile and quit | 15:14 |
| asac | ok | 15:15 |
| ogra | to load/save the set of options you picked | 15:15 |
| ogra | asac, reload :) | 15:28 |
| asac | ogra: good ... maybe in (TEMP) in brackets | 15:31 |
| asac | ;) | 15:31 |
| asac | but its ok | 15:31 |
| ogra | yeah, thats easy to add when i code that stuff ... its currently all glade to get a grasp of the layout i want | 15:32 |
| ogra | for mockups there is nothing better than glade :) | 15:33 |
| asac | oh wasnt there the idea to also allow adding .deb files? | 15:33 |
| ogra | yes, thats for later though | 15:34 |
| asac | k | 15:34 |
| asac | only one additional mirror? | 15:34 |
| asac | or a list of? | 15:34 |
| ogra | one for now | 15:35 |
| ogra | the mirror stuff can definately need some extra love later (i'll turn that into post FF bugs) currently it needs to be a properly set up ubuntu archive | 15:37 |
| ogra | i'd like to make it handle PPAs as well but that needs some extra gpg fiddling in the code thats not there yet | 15:37 |
| asac | i think its ok ;) | 15:47 |
| asac | just wondered if a syntax like in pbuilder is allowed | 15:47 |
| asac | that allows you to specify more than one mirror in one line iirc | 15:48 |
| ogra | well, that can surely be added... just a check for comma in the argument and split accordingly | 15:49 |
| ogra | heh, i just wanted to point jamie to commanet #3 on http://ograblog.wordpress.com/2010/02/15/the-shiniest-and-fastest-arms-ever-in-ubuntu/ | 15:49 |
| ogra | i guess he knows why he just disconnected :P | 15:49 |
| dmart | Hi guys, can you remember who was looking at the Thumb-2 issues in gmp? Was it dyfet? | 16:36 |
| * ogra thinks so | 16:36 | |
| ogra | but you might not catch him today (national holiday in the US) | 16:37 |
| lool | dmart: According to https://bugs.launchpad.net/bugs/513732 he was assigned shortly | 16:40 |
| ubot4 | Launchpad bug 513732 in gmp (Ubuntu Lucid) (and 1 other project) "[arm] needs porting to thumb2 (affects: 1)" [High,Triaged] | 16:40 |
| dmart | thanks | 16:41 |
| * jmc93739653 finds himself in the role of a sterotypical American, as he didn't know it _was_ a holiday in the US today. | 16:48 | |
| Martyn | bank holiday though | 16:50 |
