| MrCurious_ | anyone here know how to manually install omap4 addons on a pandaboard? | 03:07 |
| MrCurious_ | scratch that, accidentally solved it | 03:08 |
| MrCurious_ | ubuntu on pandaboard is stuck in the install loop. does anyone know the command to break it out of tha tloop | 05:44 |
| MrCurious_ | it keeps asking keyboard, location, username, password, then resets and repeats | 05:44 |
| MrCurious_ | ubuntu 11.10 desktop omap4 image | 05:45 |
| MrCurious_ | scratch that remembered oem-config-remove | 05:46 |
| twb | I'm surprised it doesn't remove oem on its own -- unles it doesn't have write access to the ramdisk? | 05:52 |
| MrCurious_ | beats me | 05:53 |
| MrCurious_ | i did it manually, and the train is now back on the tracks | 05:53 |

| marvin24 | looks like ubuntu does not provide a "xf86-video-modesetting" driver | 06:52 |
| twb | marvin24: ubuntu's kernel does KMS, but probably not for relatively obscure arm GPUs | 06:56 |
| marvin24 | well, I wouldn't name geforce/light an obscure arm GPU ... | 06:57 |
| twb | Shrug | 06:57 |
| twb | Compared to the vast numbers of x86-y intel/ati/nv GPUs, it is | 06:57 |
| twb | That's what I meant | 06:57 |
| marvin24 | I just wanted to test it on my ac100 with the newly tegra drm posted yesterday | 06:58 |
| marvin24 | but there's still other stuff to do and compiling it myself should be too difficult | 06:59 |
| twb | What I do know, is that on my tegra2 TF101, I have a native-resolution fbcon. | 07:00 |
| twb | I kinda assumed that meant it had KMS, but i haven't investigated. Oh- but that's with the android kernel, not the ubuntu kernel | 07:00 |
| marvin24 | twb: I was talking about mainline code | 07:02 |
| marvin24 | there is fbdev for tegra yet | 07:03 |
| twb | lilstevie told me the GPU support is best (for tf101, but they're mostly the same) in the Chrome OS kernel | 07:03 |
| lilstevie | not at the moment it isn't :p | 07:04 |
| twb | I have native res in my fbcon and that's all I really care about | 07:05 |
| lilstevie | heh | 07:05 |
| lilstevie | yeah | 07:05 |
| lilstevie | cause your odd and use xinit for everything | 07:05 |
| marvin24 | well, android is on 2.6.39 (I guess) and chromeos on 3.0 ... | 07:06 |
| lilstevie | marvin24: specific case is neither for those | 07:06 |
| lilstevie | CrOS is at 2.6.38 and android at 2.6.36 | 07:06 |
| twb | It would be NICE if the animated gif didn't make xinit /usr/bin/midori http://www.bom.gov.au/products/IDR023.loop.shtml#skip visibly laggy, but not enough that ICBF maybe breaking my only working computer | 07:06 |
| lilstevie | cause the 2.6.39 android kernel is silly | 07:07 |
| marvin24 | mmh, I don't know which kernels are shipped with which version (of android or chromeos) | 07:07 |
| marvin24 | but ac100 has a chromeos kernel with accel'ed X | 07:07 |
| marvin24 | and it is version 3.0 (but still too old for precise) | 07:08 |
| marvin24 | so we badly need a newer kernel sooner or later | 07:08 |
| lilstevie | tf101 can have accelerated X with .39 but it is stupid | 07:08 |
| lilstevie | there is some odd bug | 07:08 |
| lilstevie | breaking fbdev | 07:08 |
| marvin24 | no console? | 07:08 |
| lilstevie | yep | 07:08 |
| lilstevie | and f'd colours | 07:08 |
| marvin24 | same here on the nv 3.1 kernel | 07:08 |
| marvin24 | I posted something on the tegra forum, but no reply | 07:09 |
| lilstevie | heh | 07:09 |
| marvin24 | lilstevie: anything on xda-developers, you know of? | 07:09 |
| lilstevie | nope | 07:09 |
| twb | fucked as in yuv thinking its rgb kinda thing? | 07:09 |
| lilstevie | I am otherwise sidetracked with [redacted] | 07:10 |
| lilstevie | twb: yes | 07:10 |
| marvin24 | so let's hope the open source driver will make fast progress | 07:10 |
| twb | I didn't know there even was an accelerated open driver for it | 07:10 |
| lilstevie | its new | 07:10 |
| twb | ah, cool | 07:10 |
| lilstevie | this kind of new http://www.phoronix.com/scan.php?page=news_item&px=MTA4NjA | 07:11 |
| lilstevie | there are a few other little whispers that I am hearing from nvidia, but they are no more than whispers | 07:14 |
| lilstevie | we are having some good luck with getting 3.1 running on the tf201 though | 07:16 |
| lilstevie | so far we can boot and mostly use android with it | 07:16 |
| twb | Do you get the impression that nvidia are slowly getting a clue about dealing with the FOSS community? | 07:18 |
| twb | The tf is the first product I've bought from them EVER since they have such a bad rep | 07:18 |
| lilstevie | well the whispers I am hearing are that they are starting to embrace FOSS, at least in the arm sector | 07:18 |
| twb | Probably because it's not their core market | 07:19 |
| twb | Sounds like I should continue to boycott them on the desktop/server segment | 07:19 |

| serishema | The arm-ubuntu and ubuntu core rootfs FAQs are not clear on who is and is not a developer. | 10:02 |
| infinity | ? | 10:03 |
| serishema | I've built stable kernel source for armv7 (920T core, WM8505/Via8505) on one of those generic 7" netbnooks | 10:03 |
| infinity | Anyone who wants to write software is a developer, I imagine. | 10:03 |
| serishema | ahh ok | 10:03 |
| infinity | I'm not sure what your statement means. | 10:03 |
| infinity | (Which FAQ are you referring to?) | 10:04 |
| serishema | infinity: https://wiki.ubuntu.com/Core | 10:04 |
| serishema | this one. | 10:04 |
| infinity | Also, the 920T isn't ARMv7... | 10:04 |
| serishema | infinity: i was meaning that I will probably not contribute anything useful to the project | 10:05 |
| serishema | but still want to hack on it | 10:05 |
| serishema | andl that peice of info saves me a lot of effort to just get a crash at boot up doesn't it | 10:05 |
| infinity | A 920T is probably v4t... | 10:06 |
| * serishema didn't know and it's on the channel topic. Arm cores != ISAs how embarassing | 10:06 | |
| serishema | that explains why it is so hopelessly slow | 10:06 |
| infinity | So, not even remotely supported by ubuntu-core. | 10:06 |
| infinity | Debian may well support it. | 10:06 |
| serishema | The actual chip is a via/wondermedia 8605 @ 600 Mhz | 10:06 |
| * serishema is wrong about the 920t core part | 10:07 | |
| infinity | Sure, it's not about slow, it's about pure incompatiblity. | 10:07 |
| * serishema realizes it would be an ISA / EABI issue | 10:07 | |
| serishema | so the wm8605 is definately an arm v4? and not v7? | 10:07 |
| infinity | Oh, an 8605 sounds more like an ARMv7. ;) | 10:07 |
| serishema | ahh | 10:07 |
| serishema | good | 10:07 |
| serishema | I guessed from the /board directory name in the wmt uboot code | 10:08 |
| infinity | But yeah, slow it will be, relatively speaking. | 10:09 |
| serishema | infinity: tl;dr basically I had been living under a rock (read: working for a boss who makes her run and develop for windows) for too long and wasted effort trying to write drivers for the on chip hardware when they actually exist | 10:09 |
| * serishema is not expecting this to run X btw if that makes a difference | 10:09 | |
| infinity | It could run X, I'm sure. | 10:09 |
| infinity | And many other shiny things. | 10:09 |
| infinity | But yeah, it'll probably perform similarly to a beagleboard, or a Nokia n900, none of which are particularly speedy by today's standards. | 10:10 |
| infinity | So, patience will be a virtue. ;) | 10:10 |
| * infinity is surrounded by fast ARM kit, and keeps forgetting that's a relatively new invention. | 10:11 | |
| serishema | basically if it ran ssh, rdesktop and a browser (chrome or firefox,) vi, basic shell prompt tools.. could connect to the internet via my nokia 2730 classic and decode and play mp3/ogg vorbis, etc i'd be really pleased with that | 10:11 |
| serishema | This is essentially intended as a mobile dumb terminal. | 10:11 |
| serishema | All real processing happens on amazon EC2 anyway | 10:12 |
| infinity | Well, any of that's doable. | 10:12 |
| serishema | so it was a natural choice to use something so cheap it was virtually disposable rather than a real laptop :) | 10:12 |
| infinity | We build out full userspace for ARM, so... It really comes down to kernel and video support for that SoC, which we obviously don't support out of the box. | 10:12 |
| infinity | s/build out/build our/ | 10:12 |
| infinity | (And, I'd recommend basing your work on precise/armhf ... Especially on a slower SoC, you'll be glad for the performance boost) | 10:13 |
| infinity | Unless you're stuck using binary softfp drivers from a vendor. :/ | 10:13 |
| infinity | Then armel it is. | 10:13 |
| serishema | this is VFP? | 10:15 |
| * serishema can't get her hands on any vendoer specific code. | 10:15 | |
| infinity | Well, it's all VFP, it's the ABI that changes. | 10:15 |
| infinity | Welcome to the confusing world of ARM. | 10:15 |
| serishema | time for a rebuild then. | 10:16 |
| infinity | soft = soft floating point, softfp (which our armel port is) = vfp ops with soft calling conventions, hard = vfp ops with new calling convention to make use of extra registers, breaking ABI. | 10:16 |
| infinity | ubuntu-armhf/debian-armhf = hard, ubuntu-armel = softfp, debian-armel = soft | 10:17 |
| serishema | basically I got given a bricked one of these netbooks bricked. | 10:18 |
| serishema | for free | 10:19 |
| serishema | I've got as far as vfs: cannot mount root fs on uknown block (cos I haven't even made a root fs or initrd) | 10:19 |
| * serishema is mostly just curious to see if there is a easier way than doing everything from scratch :) | 10:20 | |
| infinity | Well, at least you have a kernel. | 10:20 |
| infinity | As for "from scratch", given that no installer will work for you, you get to put a tiny bit of effort in. | 10:20 |
| infinity | But using ubuntu-core as your rootfs will work fine. | 10:20 |
| infinity | Just need to maybe chroot in and add a user (or set a root password) before you try stuffing it on another device. :P | 10:21 |
| serishema | nice. I most likely just have to recompile with the right eabi | 10:22 |
| serishema | I am pretty sure I used armel | 10:23 |
| serishema | which I don't want | 10:23 |
| infinity | The kernel doesn't care. | 10:23 |
| infinity | You're fine. | 10:24 |
| infinity | Same kernel can run armel and armhf userspaces. | 10:24 |
| serishema | oh. so the kernel will load any elf for init with the correct header and ISA type? | 10:24 |
| serishema | and an eabi is a userspace dynamic linker thing? | 10:24 |
| infinity | Basically, yeah. | 10:25 |
| serishema | ahh this is a good thing | 10:25 |
| serishema | I was going to just gcc -static everything to avoid this problem | 10:26 |
| infinity | Ew. | 10:26 |
| serishema | but that would be unrealistic on a board with 256mb of ram | 10:26 |
| serishema | I assume running swap space on a SD card is a bad idea? | 10:26 |
| infinity | Very. | 10:27 |
| ogra | works, but is no fun at all | 10:27 |
| infinity | Unless you like throwing out cards. | 10:27 |
| infinity | (It's also just dead slow) | 10:27 |
| * ogra hasnt managed to kill a card with that yet but its close to unusable if you start swapping | 10:27 | |
| infinity | Keeping your VM commit under your RAM size is the saner option, if you're building for a specific use case. | 10:27 |
| ogra | and i have cards that are constantly in use for 2 years | 10:27 |
| infinity | ogra: You're a very lucky man. | 10:28 |
| infinity | ogra: Or your definition of "constantly" is different from mine. | 10:28 |
| serishema | I just assumed that the write perf would suck too much to be useable. | 10:28 |
| serishema | I didn't think about it wearing out the card | 10:28 |
| ogra | well, in my testbuild machines i always use the same cards | 10:28 |
| infinity | serishema: Write performance is awful, but wear is the real concern. | 10:28 |
| ogra | across the releases | 10:28 |
| infinity | serishema: Anal retentive SSD owners often swap to external rotary disks for wear reasons. | 10:28 |
| infinity | (Or people like me just don't use swap) | 10:29 |
| * serishema nods | 10:29 | |
| serishema | if I can't run ssh on a single VT with 256Mb of ram and no swap I have done something seriously wrong :) | 10:30 |
| infinity | Indeed. | 10:30 |
| serishema | it worked on my 486 with 8Mb | 10:30 |
| serishema | 10 years ago | 10:30 |
| infinity | Well, times have changed a bit since kernel 2.0 | 10:30 |
| serishema | we can't have all forgotten how to program because of java, etc that badly | 10:30 |
| infinity | But, yeah, 256 is still "a lot" until you get into fancy desktop environments. | 10:30 |
| serishema | and compilers are better so I assume any hand written arm ASM will be trash compared with gcc's output with -O2? | 10:31 |
| serishema | which wasn't nessacarly true on 486 in 1999 | 10:31 |
| ogra | oh, fun, compiz FTBFS | 10:31 |
| ogra | ah, KDE issue | 10:31 |
| ogra | phew ... wasnt my patch | 10:32 |
| infinity | serishema: Depends on the quality of your assembly, or what you're trying to do. | 10:34 |
| infinity | serishema: (Also depends on the quality of your C, as a good C programmer knows more or less what the compiler's going to optimise out anyway) | 10:35 |
| infinity | serishema: But yeah, in general, GCC's not awful. | 10:35 |
| serishema | if i'm writing asm it's because i'm doing eairly power up and can't do it in C. I hate ASM. | 10:35 |
| infinity | ;) | 10:36 |
| * serishema just stole the code WMT was forced to release for GPL violations for dram controller init | 10:36 | |
| serishema | I hate that stuff | 10:36 |
| serishema | Board designers problem | 10:36 |
| serishema | I have designed boards, but reverse engineering an unknown board is too hard for me :) | 10:37 |
| serishema | I will definately need to get a newer uboot on it | 10:37 |
| serishema | theirs is full of crappy bugs | 10:37 |
| infinity | Meh. If it's good enough to jam some blobs at some offsets and jump, who cares? | 10:38 |
| serishema | true. | 10:38 |
| serishema | The only actual bug which matters is the power button GPIO | 10:38 |
| serishema | which doesn't have a proper debounce, just a delay by a constant | 10:39 |
| serishema | but the real delay it should wait varies with the battery voltage | 10:39 |
| serishema | so you have to press the power button 10 times before it will turn on | 10:39 |
| infinity | I'm unconvinced that anything related to power buttons is ever correct on any ARM device I own. | 10:39 |
| infinity | From dev boards to phones to... Well, everything. | 10:39 |
| serishema | that's normal? | 10:39 |
| serishema | I noticed a // can't power off myself comment on a function which jumps into some bizare assembly | 10:40 |
| infinity | Well, your specific issue isn't necessarily normal (though I have two phones that behave like that). | 10:40 |
| serishema | which appears to among other things set the hibernate flag (WMT specific) | 10:40 |
| infinity | But I have other boards that are equally but differently confused about what power buttons do. :) | 10:40 |
| infinity | And a netbook that never actually powers off, just goes into a suspend state. | 10:41 |
| serishema | that would explain my mysterious battery drain | 10:41 |
| serishema | and the meaning of the // can't power off myself comment | 10:41 |
| infinity | Potentially, yeah. | 10:41 |
| serishema | ahh.. so is this software controllable at all? I can get my hands on a JTAG, etc. | 10:42 |
| serishema | so reflashing the bootloader is OK | 10:42 |
| infinity | Depends on the SoC. | 10:42 |
| infinity | That's a big "maybe". | 10:42 |
| serishema | when i connect the battery does it actually jump to __start or is that board specific? | 10:42 |
| infinity | And I don't know anything about the one you've got. | 10:42 |
| infinity | That's also board specific. | 10:42 |
| serishema | ahh ok. | 10:42 |
| infinity | Some reset on power, and jump somewhere sane, some just start garbled and wait for a keypress event. | 10:43 |
| infinity | (ie: a soft power button that shouldn't even exist) | 10:43 |
| serishema | urgh | 10:43 |
| serishema | so just wiring a hardware power switch onto the battery is a bad idea | 10:43 |
| serishema | since it probably wouldn't work | 10:43 |
| infinity | Unless it would. | 10:43 |
| infinity | It would work on a Pandaboard. | 10:44 |
| infinity | (Maybe even all OMAP SoCs) | 10:44 |
| serishema | OMAP SoCs are the only ones i've seen which I don't think are insane | 10:44 |
| infinity | It wouldn't work for beans on an iMX53, which insists on powering on to confusion. | 10:44 |
| serishema | unfortunately they are too expensive | 10:44 |
| serishema | I get my arm stuff for free because people give me their bricked devices | 10:45 |
| serishema | usually they have not even overwritten the boot loader, so a board/soc specific micro SD card can load a kernel onto them | 10:45 |
| serishema | otherwise.... it's down to the university electronics lab for some unauthorized use of university resources :) | 10:46 |
| serishema | anyway it doesn't matter. I will just put the 26 amp hour deep cycle battery which is just sitting on my floor on float charge in my car as a 2nd battery | 10:48 |
| serishema | and then it can waste as much power with soft off as it likes :) | 10:48 |
| serishema | I occasionally use it to power flourecent lights during power cuts in winter, but that's about it | 10:49 |
| * serishema lives in the wop wops so every time the wind gets up the power and xDSL go out | 10:49 | |
| serishema | anyway enough blathering. I will download this and put it in qemu-system arm and see if I can get it to go | 10:50 |
| serishema | infinity: and as for the orriginal question. I will just subscribe to both mailing lists and lurk | 10:51 |
| serishema | and should I happen to accidentally do something useful I will post the patch :) | 10:51 |
| infinity | Heh. Sure. | 10:51 |
| infinity | #debian-arm on oftc is another place worth lurking. | 10:51 |
| serishema | oftc? | 10:51 |
| infinity | irc.oftc.net | 10:51 |
| serishema | ahh. another fs/oss related net? | 10:52 |
| ogra | debian hides there :) | 10:52 |
| infinity | Yeah | 10:52 |
| infinity | irc.debian.org points to oftc. | 10:52 |
| serishema | I wonder where #debian went | 10:52 |
| infinity | So, that would be your answer. ;) | 10:52 |
| serishema | Cool | 10:52 |
| infinity | We only moved, like, a decade ago. | 10:52 |
| infinity | *cough* | 10:52 |
| serishema | hhyaha | 10:52 |
| * serishema disappeared sometime around kernel 2.6.35 | 10:53 | |
| ogra | not true, i remember still seeing debian channels around at warty days | 10:53 |
| serishema | and has just come back | 10:53 |
| infinity | ogra: Yeah, the move was slow. | 10:53 |
| ogra | but close to a decade already :) | 10:53 |
| serishema | naturally it is taking forever to get back up to speed on everything | 10:53 |
| serishema | there have been so many changes in 3.x | 10:53 |
| serishema | but I just grabbed the source and broke stuff, rather than trying to find answers on the internet | 10:53 |
| serishema | hopefully that wasn't stupid | 10:53 |
| infinity | That's the best way to do it, IMO. :P | 10:54 |
| infinity | Even if you end up duplicating effort, you learn. | 10:54 |
| infinity | And then you can submit patches and make the various subystem maintainers cry. | 10:54 |
| serishema | haha. I'm not that evil | 10:54 |
| infinity | I derive so much pleasure every day from reading davidm's rants about idiot submissions. | 10:55 |
| serishema | link? | 10:55 |
| serishema | oh .. I shall have to join that mailing list too? | 10:55 |
| infinity | I wouldn't subscribe to LKML, if I were you, unless you're a masochist. | 10:55 |
| serishema | oh LKML? | 10:55 |
| serishema | I've heard the horror stories | 10:56 |
| serishema | didn't realize | 10:56 |
| * serishema wouldn't even attempt to get a patch into mainline | 10:56 | |
| infinity | Well, Dave's rants tend to be on places like his G+ account, and in private with friends, but. LKML's educational, if you're bored. | 10:56 |
| infinity | I tend to stay on the other side of the syscall layer, but a disturbing number of my friends are kernel developers. | 10:56 |
| serishema | the right side generally | 10:57 |
| infinity | Both sides suck. :P | 10:57 |
| infinity | It's just insanity to try to work with both. | 10:57 |
| serishema | but I had the misfortune of actually being able to make sense of the wrong side of the syscall layer of that certain popular proprietary OS | 10:57 |
| serishema | haha snap | 10:57 |
| infinity | So, I let other people do kernel crap, and I'm sitting here with 5 parallel glibc builds going right now. | 10:57 |
| serishema | So before the recession I got paid as much as $80US an hour to do consulting with user mode/ kernel mode interface crap on windows drivers | 10:58 |
| serishema | mostly for fixing STOP IRQL_LESS_THAN_EQUAL | 10:58 |
| serishema | I don't remember the code | 10:58 |
| serishema | I don't want tio | 10:58 |
| infinity | Everyone's favourite bluescreen. | 10:58 |
| serishema | Yeah. | 10:58 |
| serishema | Since it's ALWAYS caused by the dev not reading the docs :) | 10:59 |
| serishema | unfortunately this includes MS internal devs | 10:59 |
| serishema | on wincore who should know better | 10:59 |
| infinity | I never did learn enough to know what it meant. Based on the constant name, I'm assuming integer over/underflows and a lost pointer to an IRQ or something? | 10:59 |
| serishema | Nah | 10:59 |
| serishema | IRQL is an abstraction | 10:59 |
| serishema | a moronic one | 10:59 |
| infinity | Of course. | 10:59 |
| serishema | it represents IRQ mask registers on the board/CPU specific interrupt controller | 10:59 |
| serishema | basically if you don't know that certain things require eg the timer interrupt to be masked off | 11:00 |
| serishema | you shouldn't be writing drivers | 11:00 |
| serishema | But MS came up with an abstraction to make it easier which actually makes it harder | 11:01 |
| infinity | Ignorance has never prevented driver development in the past. | 11:01 |
| serishema | NT kernel = bastardized version of VMS | 11:01 |
| * serishema doesn't even have windows installed | 11:01 | |
| infinity | I used VMS in high school, but we never wrote to the hardware. | 11:01 |
| serishema | i only read about VMS | 11:02 |
| serishema | for class | 11:02 |
| serishema | before my time | 11:02 |
| infinity | For some reason, they didn't think that doing kernel development classes that would let us crash the entire school by offlining the VAX would be a good idea. | 11:02 |
| serishema | they were probably right | 11:03 |
| infinity | Probably. ;) | 11:03 |
| serishema | I didn't learn how to do windows kernel at university | 11:03 |
| serishema | basically I was at a school which forced us to use Windows | 11:03 |
| serishema | so at that age I had the naevity to try and make it not suck | 11:03 |
| infinity | My friend's doing a CS degree right now, and I'm moderately impressed that most of their classes are on Linux systems. | 11:04 |
| serishema | I became the bane of the network admins for all my custom stuff which some how ran when I logged in even though they had supposedly disabled user login scripts | 11:04 |
| infinity | Most of his profs are idiots. But at least they're learning on open systems. | 11:04 |
| serishema | Yeah I transfered | 11:04 |
| serishema | Being forced to use windows was the lesser evil than being the only girl in a class of 185 with an openly mysogenistic bigot for a professor | 11:04 |
| serishema | getting my boobs grabbed and being asked if they were real and responding with a ju jisu wristlocking was a day in the life | 11:05 |
| serishema | But their course was also 10 years out of date | 11:05 |
| infinity | You got groped? Seriously? | 11:06 |
| serishema | In terms of material | 11:06 |
| infinity | What the fuck is wrong with people? | 11:06 |
| serishema | infinity: it was a get wasted, party and get laid type of school | 11:06 |
| serishema | I missed the memo | 11:06 |
| infinity | I mean, I'm used to geeks being socially inept, and moreso with women, but... Wow. | 11:06 |
| serishema | people who actuially wanted to work went else where | 11:06 |
| serishema | by other students only.. but yeah. | 11:06 |
| infinity | Sounds lovely. :/ | 11:07 |
| serishema | if a staff member did that the cops would hear about it. But they quickly learnt that I was not to be got on the wrong side of | 11:07 |
| * serishema lived in ghettos .. built computers out of rubbish and learnt C instead of participating in drugs/gangs, etc | 11:08 | |
| infinity | Right, remind me not to invite you to the Ubuntu-ARM frat kegger. | 11:08 |
| serishema | depends. | 11:08 |
| serishema | infinity: I won't comment since freenode: "there are no girls on the internets" will be in effect.. but let's just say my boyfriend has another girlfriend and I am fine with this. | 11:09 |
| * serishema isn't your average blond | 11:09 | |
| serishema | anyway this is getting far too OT | 11:09 |
| serishema | PM? | 11:09 |
| XorA | serishema: you sound kickass :-D | 11:13 |
| XorA | backlog was one of the more enjoyable return to work after lunch reads Ive had for a while | 11:13 |
| serishema | hi XorA | 11:14 |
| XorA | VMS is a long and distant memory | 11:14 |
| serishema | XorA: when it comes to VMS I actually don't know what I'm talking about | 11:14 |
| serishema | i'm 27 so therefore too young to have seen a real live VMS system | 11:15 |
| XorA | ah right, at univerity the student email/blah system was VMS | 11:16 |
| tomtiger11 | infinity: Why try Debian? | 11:16 |
| XorA | I was already used to posix style from Amiga so all the [blah]bleh; stuff used to confuse me until I got the hang of it | 11:17 |
| serishema | tomtiger11: I suspect he was answering my questions when I thought my chip was something older and ubuntu core wouldn't go . | 11:17 |
| infinity | tomtiger11: Why provide context with your question? | 11:17 |
| StevenK | I've seen a VMS system. It was even running. It just wasn't doing anything. | 11:17 |
| serishema | infinity: *steal* | 11:17 |
| tomtiger11 | infinity: Seriously, Is ubuntu-arm incompatible with Raspberry Pi? | 11:18 |
| infinity | tomtiger11: Yes. | 11:18 |
| XorA | tomtiger11: yes, Raspberry Pi is old technology | 11:18 |
| tomtiger11 | infinity: Is it the RAM? | 11:18 |
| infinity | tomtiger11: The Pi is ARMv6, we build for ARMv7. | 11:18 |
| tomtiger11 | Oh | 11:18 |
| XorA | you have to be nimble to keep up with the ubuntu boys | 11:18 |
| XorA | /girls | 11:19 |
| ndec | ogra: do you think we still need our biweekly call? | 11:21 |
| * serishema much prefers "get a real computer" or "bitty box" and leaving it at that :) | 11:24 | |

| xranby | tomtiger11: bring the question to the next UDS, to lower the optimization level for the community maintained armel to get back to debian level now when ubuntu-arm have switched to use armhf | 12:00 |
| infinity | xranby: It's already being discussed internally. | 12:05 |
| infinity | xranby: And, honestly, while it would be a community port, it needs to be driven by Canonical for infrastructure reasons, so you may as well let us beat the horse dead a bit first. | 12:05 |

| pnphi | i want to build the package for Ubuntu ARM | 12:07 |
| pnphi | how do i do ?? | 12:07 |
| xranby | pnphi: you have some ptions 1. setup a complete build environment on a ubuntu arm machine and simply build it using dpkg-buildpackage | 12:08 |
| xranby | 2. use xdeb to cross compile a package | 12:08 |
| pnphi | from source of package ubuntu ?? | 12:10 |
| xranby | pnphi: yes from source | 12:10 |
| pnphi | by the way | 12:11 |
| pnphi | in the Chroot, can i build the package ? | 12:11 |
| pnphi | from source | 12:11 |
| xranby | yes, as long as you have installed all compilers inside the chroot | 12:12 |
| pnphi | what link will i add source list ?? | 12:13 |
| pnphi | that i can get source | 12:13 |
| xranby | pnphi: deb-src http://archive.ubuntu.com/ubuntu/ precise main universe restricted | 12:13 |
| pnphi | ok | 12:13 |
| xranby | its the same source archive for all architectures | 12:13 |
| pnphi | for all ? ok i do | 12:14 |
| pnphi | ok thank you so much | 12:15 |
| xranby | pnphi: youre welcome | 12:15 |
| xranby | infinity: ok i take canonical wants to try a neon build .. what other optimizations are currently untested= | 12:16 |
| xranby | ? | 12:16 |
| infinity | xranby: Err, we do? | 12:16 |
| xranby | let me rephrase the question.. what is it left to flog on the horse? :) | 12:17 |
| infinity | No, no. The other direction. | 12:17 |
| infinity | As in, we also want to drop the baseline for armel. | 12:17 |
| infinity | But we're discussing in-house how much effort that will be, and if we really want to do it. | 12:18 |
| xranby | ok, thank you for the heads up | 12:18 |
| pnphi | where is the tutorial for xdeb ??? i don't search The xdeb | 12:23 |
| xranby | pnphi: https://wiki.linaro.org/Platform/DevPlatform/CrossCompile/UsingXdeb | 12:35 |
| xranby | pnphi: wookey are the person to ask about current xdeb status | 12:36 |
| ogra_ | ndec, not really i think, in ubuntu we just swallow what linaro gives us nowadays, but for ppisati it is important to get the kernel issues across, i wonder if we could take that bit to mail or so | 12:38 |
| ndec | ogra_: ok. i see. we just need to make sure ppisati, sebjan , me and andy discuss sometimes... | 12:39 |
| ogra_ | right, i dont know how important the call is for ppisati ... i guess thats something he needs to answer | 12:39 |

| rsalveti | ogra_: I don't know if you saw it yesterday, but it'd need to change vram from 32 to 40 at panda | 15:34 |
| rsalveti | to make SGX to work properly, with flip chain and such | 15:34 |
| ogra_ | rsalveti, yup, i did, i forgot to ask infinity if he had changed it already | 15:34 |
| ogra_ | wasnt there also the option to drop the mem= args too ? | 15:35 |
| rsalveti | didn't yet open a bug for it, as I know we have tons of places with that thing hardcoded | 15:35 |
| ogra_ | since we dont have ducati support in this kernel ? | 15:35 |
| rsalveti | not with current kernel I guess | 15:35 |
| rsalveti | oh, that's true | 15:35 |
| rsalveti | the next support will be with the newer kernel | 15:35 |
| * ogra_ will make sure that changes before release | 15:35 | |

| MrCurious_ | anyone know anything about a gstreamer0.10-plugins-bad package and how to get around this show stoper | 18:24 |
| MrCurious_ | looks like that package is corrupt | 18:25 |
| MrCurious_ | and reflash and retry :/ | 18:29 |
| rsalveti | MrCurious: you mean at the TI PPA? | 18:37 |
| MrCurious_ | not sure what you mean? | 18:37 |
| MrCurious_ | the ti licence accepting? | 18:38 |
| MrCurious_ | i installed ubuntu 11.10 desktop omap4 | 18:38 |
| MrCurious_ | then did apt-get update upgrade and dist-upgrade | 18:38 |
| MrCurious_ | then tried to install ubuntu-omap4-extras | 18:38 |
| MrCurious_ | then found gstreamer bad was failing | 18:39 |
| MrCurious_ | was following these instructions http://blog.sarine.nl/2011/12/07/installing-ubuntu-11-10-on-pandaboard/ | 18:42 |
| rsalveti | yeah, that one | 19:08 |
| rsalveti | the broken package was caused by an issue with the builder | 19:08 |
| rsalveti | there's one way to get it fixed, that's to skip the test checking | 19:08 |
| rsalveti | let me email TI about it | 19:08 |
| MrCurious_ | how do i skip the test checking? | 19:09 |
| rsalveti | needs to rebuild the package | 19:16 |
| rsalveti | if you build it locally, you'll not face that issue | 19:16 |
| rsalveti | the problem only happens at the launchpad builder | 19:16 |
| MrCurious_ | guess that means my install is on hold until they fix it | 19:17 |
| rsalveti | MrCurious: you can build it locally and install it by hand | 19:22 |
| rsalveti | I'll send the proposed fix now by email, I believe they will be able to fix it tomorrow | 19:22 |
| MrCurious_ | awesome | 19:23 |
| MrCurious_ | i am not sure where to get the sources for that, and i have never worked out how to tell apt i did sumething manually | 19:23 |
| MrCurious_ | but i think i can wait until tomorrow | 19:23 |
| MrCurious_ | oh wow! the install didnt loop around kbd, username, .... this time | 19:27 |
| infinity | rsalveti: Running the testsuite generates a broken package? That seems a bit wrong. | 19:28 |
| rsalveti | infinity: when running the test suite under qemu it basically explodes :-) | 19:29 |
| rsalveti | that's the problem | 19:29 |
| rsalveti | that's why skipping the test run fixes the build problem, because the build is fine | 19:30 |
| rsalveti | and goes fine at qemu, just when running the tests that everything breaks | 19:30 |
| infinity | Oh, I see. As in, it's actually put qemu in a broken state. | 19:31 |
| infinity | And people still think qemu is a sane and reasonable solution... | 19:31 |
| MrCurious_ | i am seeing that ppa.launchpad.net oneiric release is missing a public key, and cant be verified | 19:32 |

| infinity | scientes: Expand CAN? | 21:04 |
| scientes | infinity, Controller Area Network | 21:04 |
| scientes | its a broadcast-only (!) bus heavily used in automotive | 21:04 |
| infinity | can: controller area network core (rev 20090105 abi 8) | 21:06 |
| infinity | ^-- Should I assume that means I have one? | 21:06 |
| scientes | infinity, yeah | 21:06 |
| infinity | (That's dmesg on an i.MX53 QuickStart) | 21:06 |
| scientes | check if you have a can0 with ip link | 21:06 |
| scientes | (i.e. if there is a SocketCAN driver) | 21:06 |
| infinity | I have no can0, but that could just be a module not loaded... | 21:07 |
| infinity | Or not built in. | 21:07 |
| infinity | This kernel's somewhat sketchy... | 21:07 |
| infinity | scientes: The i.MX53 Data Sheet, at least, claims "Two controller area network (FlexCAN) interfaces, 1 Mbps each" | 21:08 |
| scientes | infinity, try modprobe flexcan mpc5xxx_can | 21:10 |
| infinity | scientes: That would work better if I had either of those modules. ;) | 21:11 |
| infinity | scientes: Did I mention my sketchy kernel on this board? | 21:11 |
| scientes | well, they are in drivers/net/can | 21:11 |
| scientes | so do a kernel rebuild! | 21:11 |
| scientes | is it mainlined? | 21:11 |
| infinity | I could just install a different kernel. The machine's my mirror right now, and I don't want to offline it. | 21:11 |

| scientes | i'm actually using a E-350 x86 board | 21:27 |
| scientes | but i'd like CAN, and with the prices of usb ones (that are just integrated ARM chips with a gadget port) it makes sense to use one of these | 21:27 |
| scientes | if i want CAN at all | 21:28 |
| GrueMaster | Not to brag, but I have tested one. Server side only though. | 21:28 |
| GrueMaster | 4x Core system, that is. | 21:28 |
