cdnjayHi, did Ubuntu 8.04 support ARMv6?05:07
micahgcdnjay: armel support was added in 9.0405:08
cdnjayOK, so was 9.04 the only version to support ARMv6 then?05:08
micahgcdnjay: and 9.10, both EOL, Debian stable is the best bet for armv6 for an Ubuntu like setup05:09
infinityI don't recall exactly when each option was changed.05:09
infinityBut yes, what micahg said.05:09
infinityInstalled an unsupported release for ARMv6 isn't a sane option.05:09
infinitys/installed/installing/05:09
micahgIIRC, Debian stable base arm support is armv4t05:10
infinityAye.05:11
micahgcdnjay: http://www.debian.org/ports/arm/ and http://wiki.debian.org/ArmEabiPort for more information05:11
cdnjaymicahg: OK, thanks. I was hoping an LTS had supported it. I guess I'll have to use Debian for Raspberry Pi.05:12

infinitycdnjay: Nothing wrong with running Debian.05:13
cdnjayinfinity: Haha, thanks.05:13
cdnjayinfinity: I haven't used it much but since Ubuntu is a fork I'm guessing they're somewhat similar?05:13
* micahg hugs infinity05:14
infinityFrom a command-line, you'll be hard pressed to really notice any major differences.05:14
infinityThe GUIs we provide are often quite different, but you can't possibly run a full Ubuntu deskop on a Pi anyway.05:14
micahgcdnjay: Debian stable has support for about another 18 months or so05:14
micahger..closer to 2005:14
micahgDebian's stable releases are supported for ~3 years, ~2 as current stable and 1 as oldstable05:15
gogasanHi everyone! I have a problem with playing videos in totem. So: http://img717.imageshack.us/img717/8930/20120311124553.png : RGB channels are moved from their positions. Is there some specific problem for arms and solution?05:16
cdnjayinfinity: No, the Pi is a bit short on RAM for that.05:18
infinitycdnjay: A "bit"? ;)05:18
cdnjayinfinity: Well, a lot short for Unity.05:19
infinityA lot short for GNOME in general.05:19
infinityxfce or lxde might barely squeeze in, but I still suspect you'd swap like made.05:19
infinitys/made/mad/05:19
infinityI'd likely only use a Pi for CLI programming fun.05:20
infinityAt which point, Debian and Ubuntu look nearly identical, other than a few little cosmetic bits like the motd.05:20
micahglubuntu might actually run decently on it05:21
infinitygogasan: No idea.  You might want to file a bug.05:21
infinitymicahg: Sure, until you wanted to, like, run applications.05:21
micahgat least for basics, not for heavy browsing or video05:21
infinityvideo should be the one thing it doesn't suck at, actually.05:21
infinityIn theory.05:21
micahgI'd just suggest running a browser other than chromium in that small footprint05:22
infinitySomething webkit-based, ideally.05:22
cdnjayinfinity: I thought minimum for Gnome was 128 MB? Pi has 256 MB.05:22
infinityWhich reminds me, I promised Maya I'd package Wildfox for her one of these days.05:22
micahgwell, aside from Firefox, that's all that's left in the archive ;)05:23
cdnjayHard to take advantage of the 1080p decoding in CLI but yea, that05:23
infinitycdnjay: I don't tend to pay attention to stated minimums.05:23
cdnjayI the more likely use.05:23
micahghmm, I shouldn't say that, I think we might have imported a browser based on fltk05:23
cdnjayI = is05:24
micahgdillo might actually run decently05:24
infinityepiphany might be alright, but every time they add a new feature to make it suck less, it gets closer to firefox in memory usage, while still being nowhere near in feature parity.05:24
cdnjayAnyway, thanks!05:24
infinitymicahg: Surely, we must have a webkit-based browser in the archive?05:25
micahginfinity: firefox is going down in memory usage though, 13 is looking really good WRT memory, it used to use ~5GB resident for me and now is using ~750MB05:25
infinitymicahg: We can't only be using webkit for embedded browsing widgets...05:25
infinitymicahg: 13?  I want your crack, I only have 11.05:26
micahginfinity: sure, there's midori, epiphany, I was saying the xul based browsers are gone save Firefox and I forgot, Seamonkey05:26
micahginfinity: firefox-trunk PPA05:26
infinity(But yes, I've noticed that 11 is wildly more efficient than 10 was)05:26
infinityOh, epiphany switched to webkit?  I must have missed when that happened.05:26
micahginfinity: https://launchpad.net/~ubuntu-mozilla-daily/+archive/ppa/05:27
infinityShows how much I pay attention.05:27
micahginfinity: epiphany switched to webkit in karmic with 2.28 (upstream still supported gecko for that release, but we dropped it)05:27
infinityWell, my ffox 11 is only eating 1.5G right now.  Maybe I should try 13 and see how much gooder it is.05:28
infinityIt does make me wonder just why it was so awful in 4 through 9, though, if it was this "easy" to find enough low-hanging fruit to cut my usage.05:29
infinityI used to be at around 6G on average with this same basic set of tabs.05:29
micahginfinity: they've started pouring resources into their memshrink operation05:29
micahginfinity: https://wiki.mozilla.org/Performance/MemShrink05:30
gildeanseems also that 11 already uses a lot less memory tho'05:30
gildeani've got about 20 tabs open and just 400MB of usage05:31
micahgah, could be, I've been on trunk for a while05:31
infinitygildean: Yeah, that's what I was saying.  I've gone from ~6G to ~1.5G with the same set of tabs.05:31
infinityStill, if 13's even better, I'm willing to live on the edge for a bit.05:32
gildeaninfinity: that's pretty good too05:32
gildeani didn't test version 10, but between versions 9 and 11 it seems memory usage was cut in about half05:33
infinitymicahg: Is that MemShrink thing focussing solely on firefox, or all mozilla projects?05:34
gildeanwith a small number of tabs with no heavy web-apps open in them05:34
infinitymicahg: (Not counting shared code, of course, where they influence other projects by accident)05:35
micahginfinity: well, it affects the various parts of firefox which include the gecko core that affects other projects like thunderbird and seamonkey05:35
infinitySure, but I suspect there are any number of Thunderbird-specific inefficiencies with local caching and the like.05:36
micahgsure, right, it's not focused on those, just stuff in mozilla-central AFAIK05:36
infinityWell, it's a start anyway.05:37
infinityAnd I might give tbird another try at some point.05:37
infinityRight now, it only gets opened when someone sends me pretty mail that piping to w3c from mutt can't really make sense of.05:37
infinity(The last such mail from from the Linux Foundation... I really need to write back and take issue with the fact that the effin' LINUX FOUNDATION was sending HTML-only email instead of multipart text/html)05:39
infinityIt's enough to make a grown nerd cry.05:39
gildeani used to think that emails should be plain text05:40
infinityThey should.05:40
gildeanbut then again, html is nothing more than plain text too05:40
gildeanand i really like html, so i've changed my mind05:40
infinityBut ever since html email came along, there's been an established standard for sending both in one mail.05:40
gildeanall emails should be html05:40
infinityAnd the only people who mess up that standard are people writing broken mass-mailing software, generally.05:41
infinityMost MUAs get it right.05:41
infinityEven Outlook eventually figured it out.05:41
infinitySo, it's pretty much just lazy web developers who think it's "too hard" to read standards and implement them in their spam scripts.05:41

steev_is there an issue with the linaro 4.6.3 compiler on armhf?  if i build a kernel with it, it doesn't seem to boot.  (Sadly I haven't really debugged what's going on, was just testing on a machine I had handy, most of my machines are still packed up as I moved yesterday)11:22
steev_infinity: personally i dislike html emails as well, there is one guy in our lug who insists on sending them, so his emails are always in this ginormous text compared to everyone elses.  He also top posts so *shrug*11:23
lilsteviehtml emails are annoying11:45

aerouhello20:50
aerouI am trying to boot Ubuntu Precise image using u-boot and a tegra2 board20:50
aeroubut after typing the fatload command20:51
aerouit hangs20:51
aerouI am wondering why in the supplied boot.txt file is the fatload address 0x700000020:52
aerouwhat does this address mean20:52
aerouI was trying to find info on this in the web20:52
aeroubut couldnt find a proper description20:53
aerouWhile reading guides on how to load different linux images on different arm devices, there was always a different address parameter20:54
aerouwhich makes sense, but what does it define exactly20:54
aerouand how do I know to which address should I load the uImage to?20:54
lilsteviewhich device20:55
aerouthe Tegra2 board is the Colibri T20 from Toradex20:57
aerouand I am trying to boot Ubuntu Precise from microsdhc card20:57
lilsteviehmm20:59
lilsteviemaybe try looking at their website, cause I know Colibri mainly focused on getting WinCE on their boards21:00
lilstevienot a lot of info about linux21:00
aerouexactly21:00
aerouThey provide and Angstrom image21:00
lilsteviehave a look at the Angstrom image21:00
aeroubut no info on getting other Linux images running21:01
lilsteviethere has to be a boot.scr or boot.cmd or boot.txt in that21:01
aerouthe boot.* should only contain loading kernel and initrd, setenv paramters and the boot command itself, right?21:02
aerouhere is the output of "printenv" command in u-boot21:04
aerouTegra2 #printenv21:04

aerouIs there any info that I can use?21:04
lilsteviefatload mmc 0:1 ${loadaddr}21:12
lilstevieload the uImage to 0x40800021:12
lilsteviewith loading the uRamdisk you need to be mindful of where other things are in memoryspace21:14
lilstevieI tend to try for ${loadaddr}+uImage+a little extra in case the uImage ends up needing a little more room21:16
aerouwill try21:23
aerouSo I loaded the uImage at 0x40800021:25
aerouMy knowledge here is limited21:27
aerouI am loading the image into ram21:27
aerounow what with the initrd?21:27
aerouI see:21:28
