Mar 30 06:50:25 <plugwash> is there any equivilent of packages.ubuntu.com for ubuntu armel and armhf?
Mar 30 09:25:10 <janimo`> GrueMaster, feel free to remove https://code.launchpad.net/~gruemaster/flash-kernel/bug-961174/+merge/98874 if the corresponding bug is wontfix
Mar 30 09:25:37 <janimo`> it showed up in the sponsoring queue and I almost considered uploading it before seeing in tiny green letters that the bug is wontfi
Mar 30 09:25:46 <janimo`> LP UI is not the best
Mar 30 09:25:56 <janimo`> tiny gray letters that is
Mar 30 10:04:16 <mythos> plugwash, you man a website to lookup packages, search for/in packages, etc? no
Mar 30 10:04:20 <mythos> *mean
Mar 30 14:03:46 <traisen> What is the minimum memory that will support ubuntu arm version?
Mar 30 14:04:37 <xranby> traisen: it depend if you want to run the full desktop
Mar 30 14:05:17 <xranby> traisen: a regular unity-2d session work ok using 512mb of ram
Mar 30 14:05:28 <xranby> the system then consume around 200mb on startup
Mar 30 14:05:44 <xranby> you can of course use 256mb of ram + some swap
Mar 30 14:05:51 <xranby> that will allow you to run most applications
Mar 30 14:06:05 <xranby> if you run headless like ubuntu-core
Mar 30 14:06:14 <xranby> then you should be able to make it with 64mb of ra
Mar 30 14:06:16 <xranby> m
Mar 30 14:08:50 <traisen> Thanks, Do you know if anyone has tried it on the Lego Mindstorms NXT ? 256kbyte FLASH- und 64kbyte RAM-Speicher
Mar 30 14:10:13 <xranby> do you know which arm cpu it are using?
Mar 30 14:10:24 <traisen> Atmel
Mar 30 14:10:37 <xranby> ok, do you know the variant?
Mar 30 14:10:38 <traisen> (or do you need more info)
Mar 30 14:10:42 <xranby> i need more info
Mar 30 14:10:46 <xranby> atmel make amny cpus
Mar 30 14:10:49 <xranby> many
Mar 30 14:11:08 <xranby> off hand i can tell you ubuntu will not boot on this device
Mar 30 14:11:20 <traisen> Just a minute
Mar 30 14:11:20 <xranby> but you can most likely write code for it using the ubuntu arm gcc
Mar 30 14:11:54 <xranby> if you have a way to upload code to this mindstorm device
Mar 30 14:12:28 <traisen> Currently using gnu tool chain, but ubuntu is better known then eCos
Mar 30 14:13:21 <traisen> But wouldn't the o/s have to be a favor of ubuntu, even if a minimal version?
Mar 30 14:15:16 <traisen> AT91SAM7S256
Mar 30 14:15:23 <janimo`> traisen, ubuntu hardly fits on a device with 1000 times as much memory
Mar 30 14:15:49 <xranby> traisen: FOR THIS KIND OF DEVICE I RECOMMEND OPENEMBEDDED OR SCRATCHBOX
Mar 30 14:15:53 <janimo`> maybe the bootloader used on typical ubuntu arm hw would fit on the mindstorm :)
Mar 30 14:16:03 <xranby> OOPS
Mar 30 14:16:07 <xranby> damn capslock
Mar 30 14:16:28 <traisen> No desktop needed
Mar 30 14:16:45 <xranby> traisen: the problem are that a regular liux kernel require more than 256kb of flash
Mar 30 14:16:45 <janimo`> traisen, ecos should be pretty good for it for the type of apps you'd probably run on it
Mar 30 14:17:36 <xranby> traisen: for a minimal embedded linux system you need at least 4mb of flash
Mar 30 14:17:45 <xranby> to store the kernel and a minimal root filesystem
Mar 30 14:17:55 <xranby> and more ram
Mar 30 14:18:15 <xranby> you can compare this lego device with your usb mousepointer
Mar 30 14:18:37 <xranby> the usb mouse probably have more flash
Mar 30 14:18:46 <xranby> if it are flash based
Mar 30 14:23:31 <traisen> MB not Kb :)    eCos is working... thanks for mentioning other options, so I have something to compare against.
Mar 30 15:35:47 <janimo`> hackish patch to get mongodb run its smoketest completed, now to clean up maybe and backport to Ubuntu's stable version hopefully before 12.04
Mar 30 15:36:45 * janimo` resists being sidetracked into debugging mongo for ppc on the porter machine. 
Mar 30 16:08:34 <infinity> janimo`: Go for it, get sidetracked.
Mar 30 16:08:48 <infinity> janimo`: I thought mongo was heavily x86-centric.  Just how large is your patch?
Mar 30 16:10:07 <infinity> (Or maybe I'm confusing it with another package that had a "don't bother trying to port this" note...)
Mar 30 16:10:59 <infinity> Ahh, there it is.
Mar 30 16:11:01 <infinity>   The mongodb server depends on both little-endianness and unaligned memory
Mar 30 16:11:01 <infinity>   access, which I believe means it can only work on i386 and amd64. We believe
Mar 30 16:11:04 <infinity>   that the mongodb will be useful even it is not available for all Debian
Mar 30 16:11:06 <infinity>   supported platforms.
Mar 30 16:11:08 <infinity> janimo`: Is the above no longer true?
Mar 30 16:48:32 <tedg> Howdy folks.
Mar 30 16:48:43 <tedg> We've got a test that's using callgrind, but it's failing to link on ARM.
Mar 30 16:48:56 <tedg> Could someone take a look?  It seems like callgrind isn't built right on ARM.
Mar 30 16:49:03 <tedg> https://launchpadlibrarian.net/98928961/buildlog_ubuntu-precise-armhf.libdbusmenu_0.5.96-0ubuntu1_FAILEDTOBUILD.txt.gz
Mar 30 16:50:51 <infinity> tedg: You didn't get the memo that ARM is everyone's problem/responsibility now? ;)
Mar 30 16:51:26 <tedg> infinity, yes, that's why I'm helping -- by finding bugs :-)
Mar 30 16:51:41 <infinity> *smirk*
Mar 30 16:51:48 <infinity> janimo`: Know anything about valgrind on ARM?
Mar 30 17:54:47 <plugwash> <mythos> plugwash, you man a website to lookup packages, search for/in packages, etc? no <-- yes packages.ubuntu.com lets me search for/in packages on the official ubuntu architectures I was wondering if there was an equivilent for ubuntu armel and armhf
Mar 30 17:55:34 <mythos> plugwash, answer is no
Mar 30 17:55:46 <plugwash> ok
Mar 30 17:56:04 <mythos> the easiest way is a chroot and apt-file/apt-cache
Mar 30 18:29:01 <infinity> plugwash: packages.u.c is maintained by frank@lichtenheld.de, feel free to bug him about adding ports. ;)
Mar 30 18:31:49 <infinity> plugwash: Of course, there's also Contents-$arch on the mirrors.
Mar 30 18:52:52 <janimo`> infinity, mongodb is indeed x86 centric but not by design, they just did not care for portability much
Mar 30 18:53:19 <janimo`> and there are not many places where it needs changing but my chjanges are not the most elegant
Mar 30 18:53:55 <janimo`> so unaligned double and atomic int accesses cause traps and it is mostlt about finding and fixing those places
Mar 30 18:54:26 <janimo`> infinity, I had a fire-and-forget ARM patch sent to valgrind once but not much knowledge more besides that
Mar 30 19:01:02 <janimo`> infinity, as for the size of the mongo patch it is mongoarm.diff here, most recent comments
Mar 30 19:01:25 <janimo`> that is against master which built and ran fine, applying the same to the 2.0 branch still crashes so I have some more digging to do
Mar 30 19:01:58 <janimo`> infinity, regarding ppc, I probably need to debug it there too, after the single patch that is needed on ARM too (make char signed explicitely in one place)
Mar 30 19:02:22 <janimo`> it still crashed and the build for some reason did not have debug symbols so gdb did not help me
Mar 30 19:02:42 <janimo`> which is strange as the same default build on x86 and arm has debug symbols
Mar 30 19:03:11 <janimo`> anyway I probably need to look at it some more, probably my last chance to play with ppc if I am reading my crystall ball correctly
Mar 30 19:03:27 <janimo`> also my first time working on a ppc :)
Mar 30 19:05:27 <infinity> Heh.
Mar 30 19:05:35 <infinity> If you need access to a PPC machine to play, let me know.
Mar 30 19:05:45 <infinity> Although, I guess you have access to the porter in the DC too.
Mar 30 19:06:01 <infinity> But yeah, the claims that it's endian-specific don't bode well for PPC.
Mar 30 19:06:09 <infinity> Maybe that was overstated and/or incorrect.
Mar 30 19:06:52 <infinity> If you can make it both endian and alignment clean, I'm sure the Debian maintainer would love you forever.
Mar 30 19:20:06 <janimo`> infinity, yes, it is the porter that I tried building mongo today and which crashed even after one fix which was also needed for arm
Mar 30 19:20:33 <janimo`> infinity, ah indeed, it is probably endian specific too, but that luckily did not affect arm
Mar 30 19:21:00 <janimo`> there was a mongo-nonx86 branch against 1.8 last year but it is very messy and the author no longer maintains it
Mar 30 19:21:09 <janimo`> it had fixes for all sorts including arm
Mar 30 19:22:08 <janimo`> infinity, I already had a few exchanges with antonin, pushin all but our upstart script to him to lessen delta
Mar 30 19:22:30 <janimo`> and was surprised to find out that debian packages (or the system) can break if upstart scripts are installed
Mar 30 19:22:42 <janimo`> because of some yet undeployed dpkg fix
Mar 30 19:29:51 <janimo`> ah so that's wre my diskspace went
Mar 30 19:30:00 * janimo` discovers a 21Gb log from Gnash
Mar 30 19:31:07 <highvoltage> wow
Mar 30 19:39:24 <janimo`> highvoltage, possibly the effects of always open browser+gnash installed+infrequent reboots. Anyway, removed
Mar 30 19:41:21 <highvoltage> I use the #rmrf tag on identica/twitter for things like that. like http://identi.ca/notice/50474501 and http://identi.ca/notice/71778992 :)
Mar 30 20:58:20 <Mephisto__> Hello people! I'm looking at a kernel config (versatile) for a recent kernel, I cannot seem to make em work (a part from the 2.6.22 which doesn't support ext4), any help is appreciated
Mar 30 21:25:45 <infinity> Mephisto__: Why versatile?  It's long obsolete.
Mar 30 21:25:51 <infinity> Mephisto__: Surely, you want vexpress?
Mar 30 21:27:28 <Mephisto__> well i'm a total newbie to this here's the system I'm trying to "emulate"
Mar 30 21:27:42 <Mephisto__> http://www.sealevel.com/store/relio-r9-arm9-embedded-risc-computer.html
Mar 30 21:29:42 <infinity> Oh.  Then you're almost certainly in the wrong channel, as Ubuntu won't run on that system (nor an emulated version of it).
Mar 30 21:30:43 <infinity> ARM9 is ARMv5, Ubuntu only supports ARMv7.
Mar 30 21:31:06 <infinity> Actually, that might even be v4t.
Mar 30 21:31:22 <infinity> Anyhow, you might want to try Debian, and they do have versatile kernels packaged as well.
Mar 30 21:31:36 <Mephisto__> so it's versatile right?
Mar 30 21:33:02 <infinity> Erm.  That system isn't the same thing as a versatile board from ARM, no.
Mar 30 21:33:23 <infinity> But they're perhaps vaguely similar product families.
Mar 30 21:33:45 <infinity> In either case, Ubuntu won't run on either one (old ARM versatile boards, the qemu versatile target, nor this machine you linked).
Mar 30 21:34:09 <Mephisto__> I see
Mar 30 21:34:17 <Mephisto__> thanks a lot for valuable informations and your time sir
Mar 30 21:34:26 <infinity> No problem.
