| tmzt | Stskeeps: hey :) | 07:37 |
|---|---|---|
| tmzt | can somebody point me at uds channel for this topic for tomorrow? | 07:37 |
| plars | tmzt: they are actually about to get started, but are scattered in different rooms | 07:51 |
| plars | tmzt: see: http://summit.ubuntu.com/uds-m/track/ubuntu_on_arm/ | 07:52 |
| plars | tmzt: typically, the channels take the form of #ubuntu-uds-ROOMNAME, where the room name can be found in that link | 07:52 |
| plars | tmzt: so for example, the ASoC discussion will be in mahogony, so #ubuntu-uds-mahogony. However since it's live, you would just have 1 way communication on irc to ask questions. To know what's going on, you will want to listen to the icecast stream | 07:54 |
| tmzt | thanks | 07:57 |
| tmzt | what timezone in the panel clock? | 07:58 |
| tmzt | oh, got it | 07:58 |
| tmzt | it's later than I thought | 07:58 |
| DanaG | Is there an all-discussions stream? | 08:01 |
| DanaG | Or are there multiple things at the same time? | 08:01 |
| DanaG | And do they create transcripts? | 08:01 |
| tmzt | everything is in one room? | 08:02 |
| tmzt | there seem to be two talks (X/dpkg for ex) at the same time | 08:02 |
| tmzt | in one track | 08:02 |
| tmzt | oh, the room is under the title | 08:03 |
| DanaG | I greatly prefer transcripts. | 08:03 |
| DanaG | It takes me 5 minutes to read something that could take 45 minutes to listen to. | 08:03 |
| tmzt | http://www.lczajkowski.com/2010/05/04/uds-m-remote-participation/ | 08:08 |
| DanaG | oh, and I want glx_ext_texture_from_pixmap | 08:09 |
| Stskeeps | don't we all | 08:09 |
| Stskeeps | :P | 08:09 |
| DanaG | That's 99% of my Linux 3D stuff I use regularly: compiz. | 08:10 |
| DanaG | Or how about reviving that old XGL... on top of GL ES? | 08:10 |
| hrw-uds | hi | 08:10 |
| tmzt | doesn't gallium have some kind of es emulation now? | 08:11 |
| DanaG | What timezone is uds in, anyway? | 08:11 |
| DanaG | Oh, and fglrx claims to have some GL_ES strings.... wonder how you'd use that. | 08:11 |
| hrw-uds | DanaG: european one | 08:11 |
| hrw-uds | DanaG: 09:11 here | 08:11 |
| DanaG | Probably it's as xvba-video was: not public. | 08:11 |
| DanaG | s/was/is/ | 08:12 |
| tmzt | it's a state tracker | 08:12 |
| tmzt | anybody who can comment on why recent ubuntu releases are limited to armv6mmu and if that is changing with the new branching/repo strategy? | 08:18 |
| hrw-uds | tmzt: armv6? lucid is armv7a | 08:18 |
| tmzt | right, so more generally why is this required? | 08:19 |
| tmzt | how many packages of the full repo actually require neon or vfp | 08:19 |
| lool | tmzt: All of main was rebuilt for the v7t2 transition | 08:19 |
| lool | So all of them :-) | 08:19 |
| DanaG | http://sourceware.org/redboot/ | 08:20 |
| DanaG | er | 08:20 |
| DanaG | wrong link | 08:20 |
| DanaG | https://wiki.ubuntu.com/Specs/ARMSoftbootLoader | 08:20 |
| lool | tmzt: The point is to take advantage of v7 and thumb2 instructions | 08:20 |
| tmzt | I'm aware of the requirement, I'm asking for what the justification might have been | 08:20 |
| DanaG | That reminds me of the Angstrom "kexecboot" loader on Zaurus. | 08:20 |
| tmzt | since only certain packages should benefit from those | 08:20 |
| hrw-uds | tmzt: get as much as possible from cpu? | 08:20 |
| lool | tmzt: No, everything benefits from it | 08:20 |
| * DanaG scrolls down and sees that mentioned. | 08:20 | |
| lool | tmzt: thumb2 is smaller and fits better in cache | 08:21 |
| tmzt | this has made projects such as rhobuntu and mer difficult to support a broad range of hardware with vanilla ubuntu repos | 08:21 |
| lool | the more code in cache, the faster | 08:21 |
| DanaG | "that" being "kexecboot" | 08:21 |
| tmzt | so all packages are now thumb2 code? | 08:21 |
| lool | tmzt: Sure, but if we kept v5 only, we'd be irrelevant for v7 projects | 08:21 |
| lool | tmzt: thumb2 is the compiled code | 08:21 |
| lool | it's instructions | 08:21 |
| tmzt | I can understand that for, say, gstreamer codecs | 08:22 |
| lool | tmzt: It really benefits everything | 08:22 |
| lool | tmzt: It's not like neon | 08:22 |
| lool | tmzt: what you say would typically apply for neon | 08:22 |
| lool | since most packages dont take advantage of it, and the toolchain doesn't use much of it when it can | 08:23 |
| lool | tmzt: But when you tell gcc/gas that they should generate thumb2, it makes a big difference because they will generate 16-bits opcodes instead of 32-bits ones | 08:23 |
| tmzt | how much of an improvement is thumb2 over thumb? | 08:23 |
| lool | In the end, all the little libraries and programs fit better in cache | 08:23 |
| DanaG | UEFI ARM? That's an odd idea. | 08:24 |
| lool | tmzt: It's mostly an improvement in code coverage | 08:24 |
| lool | tmzt: it wasn't really possible to use thumb for everything | 08:24 |
| tmzt | but the compiler would fall back to arm when thumb didn't support the needed instruction? | 08:24 |
| DanaG | Thu May 13 00:26:10 PDT 2010 | 08:26 |
| DanaG | time for me to go to bed. =þ | 08:26 |
| DanaG | Anyway, I suppose the eventual blueprints will be enough of a "transcript" (or rather, will distill down the overall points). | 08:27 |
| lool | tmzt: Yes, you'd have to switch back and forth | 08:28 |
| DanaG | Or stream in stereo. | 08:28 |
| DanaG | Left side in one room, right in the other. | 08:28 |
| DanaG | =þ | 08:28 |
| DanaG | http://www.arm.com/about/newsroom/24978.php | 08:29 |
| DanaG | Nifty. | 08:29 |
| DanaG | UEFI including ARM. | 08:29 |
| DanaG | Now... we just need Ubuntu to support UEFI! | 08:30 |
| DanaG | Actually, I can imagine HP, for example, liking that.... they already use UEFI on their business laptops. | 08:31 |
| crimsun | cf. https://wiki.ubuntu.com/FoundationsTeam/Specs/MaverickUefiSupport | 08:34 |
| crimsun | which was discussed the first day ;) | 08:35 |
| DanaG | Sweet. | 08:35 |
| DanaG | I've messed with UEFI on my laptop... first-gen Elitebook. Has somewhat broken memory map. | 08:36 |
| tmzt | is there any public discussion of qualcomm kernel-qcm? | 08:36 |

| ogra | NCommander, around ? | 11:16 |
| NCommander | ogra: yeah, I'm in the basement | 11:18 |
| NCommander | ogra: where are you? | 11:18 |
| ogra | NCommander, in the UI heads session | 11:18 |
| ogra | NCommander, so i talked to colin | 11:19 |
| NCommander | ogra: (I've been having some thoughts about doing hd-install, and I'm not sure this is the proper solution) | 11:19 |
| ogra | NCommander, after a bit of going back and forth we came to the conclusion that actually the best solution is an OEM image | 11:19 |
| NCommander | ogra: ? | 11:19 |
| ogra | its trivial to change livecd-rootfs to omit casper and instead add oem-config.-gtk | 11:20 |
| NCommander | ogra: didn't I suggest that earlier? | 11:20 |
| ogra | roll a live image thats going to a real FS on antimony | 11:20 |
| NCommander | ogra: its not a bad idea expect then we need a way to resize the DD'ed SD card image | 11:20 |
| ogra | nah, leave it to the user to add more partitions, we can put gparted in | 11:21 |
| NCommander | ogra: I thought your objection to doing oem-config in place of ubiquity was a speed issue and such | 11:21 |
| ogra | it is | 11:21 |
| NCommander | ogra: ugh, that stinks of HACK | 11:21 |
| ogra | but we need to fix that anyway | 11:21 |
| NCommander | ogra: fair enough. if a live image is acceptable, this works for me. | 11:21 |
| ogra | well, its not a live image | 11:22 |
| NCommander | ogra: since its trivial to drop ubiquity (we just need to change the second package installation pass) | 11:22 |
| ogra | its essentially a rootfs on a artitioned image | 11:22 |
| NCommander | ogra: well, from the perspective of image building :-) | 11:22 |
| ogra | *partitioned | 11:22 |
| NCommander | er | 11:22 |
| NCommander | hrm | 11:22 |
| NCommander | actually | 11:22 |
| NCommander | tihs is a new type of image now that I think of it | 11:22 |
| NCommander | since we'll have no squashfs | 11:22 |
| ogra | right | 11:22 |
| ogra | we only use the squashfs as a base | 11:22 |
| NCommander | ogra: I rather just have it dump a tarball and let antimony learn how to deal with it; it will greatly reduce build time | 11:23 |
| ogra | but do the content copying that ubiquity would usualy do during image build | 11:23 |
| NCommander | squashing an image takes ~1 h | 11:23 |
| ogra | yeah, true, we can add such a function | 11:23 |
| NCommander | ogra: /etc/fstab, /etc/passwd, /etc/group | 11:23 |
| NCommander | f-k-i will have to be run | 11:23 |
| ogra | the only thing that concerns me a bit is the actual image size | 11:23 |
| ogra | you dont need fstab beyond proc | 11:24 |
| NCommander | ogra: we might want to look at using livehelper instead, since this looks like a massive pain to hack onto livecd-rootfs | 11:24 |
| NCommander | oh | 11:24 |
| NCommander | fair enough | 11:24 |
| ogra | passwd and group are set up by oem-config | 11:24 |
| NCommander | ogra: but then there won't be an fstab entry for / | 11:24 |
| ogra | you dont need one | 11:24 |
| NCommander | ogra: I thought oem-config needs an account added to run at boot time | 11:24 |
| ogra | it doesnt | 11:24 |
| NCommander | casper makes one for the livecd environment, and the installer adds an ubuntu:ubuntu user for first boot | 11:24 |
| ogra | it adds one actually :) | 11:24 |
| ogra | thats the live session | 11:25 |
| ogra | oem-config doesnt need any user | 11:25 |
| NCommander | ogra: then what user does GDM log in as? | 11:25 |
| ogra | so i'd like to build two kinds of images ... | 11:25 |
| ogra | there is no gdm running, oem-config is the DM | 11:25 |
| NCommander | DM? | 11:25 |
| ogra | display manager | 11:26 |
| NCommander | ogra: the dm is started up by GDM, which is set to autologin on first boot with oem-config | 11:26 |
| ogra | an oem-config image boots into a stripped down ubiquity | 11:26 |
| ogra | ad the DM | 11:26 |
| ogra | instead of GDM | 11:26 |
| NCommander | I've got to be missing something | 11:26 |
| NCommander | But that's fine | 11:26 |
| ogra | yes :) | 11:26 |
| NCommander | ogra: er, ubiquity launchs GDM though in all cases though ... | 11:27 |
| ogra | try a rootstock build and install oem-config-gtk in it | 11:27 |
| NCommander | ogra: I'll take your word for it :-) | 11:27 |
| ogra | ubiquity doesnt touch gdm | 11:27 |
| ogra | so | 11:27 |
| ogra | i'd like us to build two images | 11:27 |
| NCommander | livecd-rootfs needs to grow a new function mode | 11:27 |
| ogra | starting out with minimal one | 11:27 |
| ogra | +a | 11:27 |
| NCommander | ogra: minimal? like just a basic command line system? | 11:28 |
| ogra | which is only a basic debootstrap+oem-config | 11:28 |
| ogra | right | 11:28 |
| ogra | we'll need a seed for that | 11:28 |
| NCommander | ogra: we can't use tasks in PPAs | 11:28 |
| NCommander | (limitation of Launchpad) | 11:28 |
| ogra | and the other one should be a stripped down netbook | 11:28 |
| ogra | thats why i want to use a seed :) | 11:28 |
| ogra | so we can have a metapackage | 11:29 |
| NCommander | ogra: right, but we'll have to make sure we keep the metapackages up to date | 11:29 |
| NCommander | :-) | 11:29 |
| NCommander | ah good, we're on the same page, we're just cross-typing each other | 11:29 |
| ogra | they live in the PPA, shouldnt be a prob | 11:29 |
| NCommander | right, we did this for Moblin | 11:29 |
| * NCommander shivers | 11:29 | |
| ogra | so what i'd like us to come up with is some idea for the size issue | 11:29 |
| NCommander | ogra: hrm, we can't put stuff on an ext4 image though | 11:29 |
| ogra | i dont want to end up with 3G images | 11:30 |
| NCommander | At least, not if we use antimony | 11:30 |
| ogra | we can use ext3 | 11:30 |
| NCommander | Slow, but doable | 11:30 |
| ogra | no pob with that | 11:30 |
| NCommander | e2tools is VERY slow :-/' | 11:30 |
| ogra | nope, pretty fast | 11:30 |
| NCommander | It is? Not the last time I used it | 11:30 |
| ogra | right, we will use gene2fs | 11:30 |
| NCommander | OH | 11:30 |
| NCommander | That works | 11:30 |
| ogra | indeed | 11:30 |
| ogra | and doesnt need root | 11:30 |
| NCommander | Right, so d-cd needs to grow a new ext2/3 backend | 11:30 |
| ogra | needs to tinker with the journal afterwards though | 11:31 |
| NCommander | I already have code on a local branch for that | 11:31 |
| ogra | so it gets converted to ext3 | 11:31 |
| NCommander | ogra: how do we do that though, we can't loopback mount as non-root | 11:31 |
| ogra | why would you loopback mount anything ? | 11:31 |
| NCommander | ogra: to twiddle the journal with tune2fs | 11:31 |
| ogra | no need for that | 11:32 |
| NCommander | unless you another way to get journals enabled | 11:32 |
| ogra | tune2fs can work on .img files | 11:32 |
| ogra | directly | 11:32 |
| NCommander | didn't know that | 11:32 |
| NCommander | Nifty | 11:32 |
| NCommander | ogra: the lack of ext4 is a bit disappointing, but not a show stopper | 11:32 |
| ogra | ext3 is fine | 11:32 |
| NCommander | ogra: so the images will have two partitions. vfat /boot, and / ext3, right? | 11:33 |
| ogra | i was planning to implement the same setup in rootstock to overcome the usage of root | 11:33 |
| ogra | so i can just copy/paste the PoC from there into antimony | 11:33 |
| ogra | three | 11:33 |
| NCommander | ogra: we can expand the partition map on first boot now that I think about it. OEM had to do that on the Dell mini's once | 11:34 |
| ogra | err | 11:34 |
| ogra | two | 11:34 |
| NCommander | We just have to look at how they did it, and then make the ext filesystem grow | 11:34 |
| ogra | but no vfat /boot | 11:34 |
| NCommander | ogra: ? | 11:34 |
| ogra | dpkg doesnt cope with vfat /boot | 11:34 |
| NCommander | ugh | 11:34 |
| ogra | we will do something similar to imx51 | 11:34 |
| NCommander | ogra: so flash-kernel voodoo? | 11:35 |
| NCommander | yeah | 11:35 |
| NCommander | Ok, so I see how this will come together | 11:35 |
| ogra | a raw hidden partition that pretends to be a flash | 11:35 |
| NCommander | d-cd will grow ext2/3 image support, that image is passed into {post-}boot scripts, and then we handle it like we do on imx51 and dove | 11:35 |
| ogra | flash-kernel will then mount that and cp uImage/uInitrd to it | 11:35 |
| ogra | that code from oem ... does that automatically grow the partition ? | 11:36 |
| NCommander | ogra: it had to, but I don't know the full story behind it | 11:36 |
| NCommander | ogra: but its a solved problem, we just need to figure out how they solved it | 11:37 |
| ogra | can you try to get your hands on that code and test it ? | 11:37 |
| NCommander | ogra: let me see if I can figure out who solved it originally, this was almost a year ago | 11:37 |
| ogra | i'll look into livecd-rootfs and the build scripts | 11:37 |
| ogra | (or feel free to do the d-cd changes and give them to me) | 11:37 |
| ogra | so we have something to get started from | 11:38 |
| NCommander | ogra: I can handle the build scripts/d-cd if you want, I have local infrastructure | 11:38 |
| ogra | fine then | 11:38 |
| ogra | i'll put an action point list together and write up an explanation of what we'll do to david | 11:39 |
| NCommander | ogra: right, so I'll make d-cd grow ext support, you'll make livecd handle making a pre-installed image | 11:39 |
| NCommander | or do you want me to handle the entirity of the image stack? | 11:40 |
| ogra | right, and you try to get your hands on the grow partition code | 11:40 |
| NCommander | (this is work I enjoy doing so I don't mind taking it) | 11:40 |
| ogra | let me make up the bulletpoint list and we look who does what then (by mail), if you want to start already, start with d-cd | 11:41 |
| NCommander | ogra: execellent, I'm just fixing up my local build infrastructure here now | 11:42 |
