**** BEGIN LOGGING AT Fri Jan 04 02:59:58 2013 Jan 04 03:40:38 wookey: This is all already fixed with some patches from doko, I'll get it into experimental (as 2.17) tomorrow, I hope. Jan 04 03:53:54 the 'don;t build libc6-prof on arm64' thing? Great - I was just abot to ask what the best way to fix that was Jan 04 03:54:37 do send me a patch as lack of libc6:arm64 is the only thing preventing me doing a load raring arm64 build stats Jan 04 03:54:58 (or do the upload) Jan 04 04:14:15 wookey: If I don't finish 2.17 over the weekend, I'll upload a 2.16 with build fixes instead. Jan 04 04:14:21 wookey: But 2.17 should happen. Jan 04 08:13:58 Hi. I'm running a large (custom) application on an omap3 device running precise. It has 256Mb RAM, no swap. This app calls a handful of script commands using traditional fork()/exec() methods. However I've seen that the fork() operation fails due to low memory, even when exec() is about to be called. Has anyone here any experience with running large apps on swap-less system and have been... Jan 04 08:14:00 ...tweaking the overcommit setting. Or is this channel the wrong channel alltogether? Jan 04 08:31:07 I'm looking for some advice getting ubuntu onto a tablet. the end goal is to run opencpn (a navigation/chartplotter app for boating.) Before I start buying devices, I'd love to know if anyone has any suggestions. Jan 04 08:35:50 nexus7 Jan 04 16:48:49 Does this page work for anyone? It keeps giving me time out errors -> https://launchpad.net/ubuntu/+source/flash-kernel Jan 04 16:50:24 Times out for me Jan 04 16:52:40 and me Jan 04 16:53:23 glad it isn't just mem Jan 04 16:53:24 me* Jan 04 16:53:28 mashing f5 got me through Jan 04 16:54:30 lol Jan 04 17:04:16 works fine here Jan 04 17:29:43 OK so I've got a chroot I'm editing a file system for the nexus 7 in. When I try to install the linux-image-nexus7 I get it stopping at this -> http://paste.debian.net/221672/ Jan 04 17:29:56 Any ideas how I could make it just auto continue instead of waiting on user feedback? Jan 04 17:33:56 export FLASSH_KERNEL_SKIP=true Jan 04 17:35:55 zou also want to install linux-nexus7, not only the image meta Jan 04 17:36:26 yep yep ogra_ Jan 04 17:36:38 in the process of merging all your packages into my Wheezy repo Jan 04 17:40:29 ogra_: same result when setting that var to true Jan 04 17:44:49 that cant be Jan 04 17:45:04 where do you set it exactly ? Jan 04 17:45:33 in the terminal I am in Jan 04 17:45:47 ogra_: -> http://paste.debian.net/221680/ Jan 04 17:47:19 shoot I gotta run out for a bit ogra_ - I'll be back later. If you think of something that might help post it with a ping for me Jan 04 17:48:00 well, tbe var should completely suppress flash-kernel Jan 04 17:48:15 oh, wait, you will nee the ubuntu flash-kernel Jan 04 17:48:20 it is forked a bit Jan 04 17:48:34 Jef91, ^^^ Jan 04 17:48:58 (the debian one wont even know about tegra3) Jan 04 17:49:20 (nor does it have the SKIP option at all) Jan 04 17:51:17 ogra_: already did that -> flash-kernel 3.0~rc.4ubuntu29 armhf Jan 04 17:52:28 hmm, then there is no reason why SKIp shouldnt work Jan 04 17:52:55 Anything else you can think of yall have modified from debian? Jan 04 17:53:01 t definitely does on all our daily builds Jan 04 17:53:10 they would fail if it wouldnt work Jan 04 17:53:24 I don't doubt it works for you ;) Jan 04 17:53:27 not really and nothing realted really Jan 04 17:53:38 hrm Jan 04 17:54:00 f-k is a pretty standlone script and the SKIP check is pretty much at the top of the code Jan 04 17:54:20 I'll just go edit flash-kernel then Jan 04 17:54:25 and manually make it skip Jan 04 17:54:50 ftse 250 Jan 04 17:55:01 really running out now. Feel free to ping me if you think of anything else ogra_ Jan 04 17:55:24 well, i'll calll it a day soon and am rather out of ideas Jan 04 17:56:15 kk ogra_ thanks for the help as always - have a good weekend Jan 04 17:57:18 /etc/kernel/postinst.d/zz-flash-kernel is the script containing the SKIP stuff btw Jan 04 17:58:31 (and /etc/initramfs/post-update.d/flash-kernel) Jan 04 18:01:08 huh ogra_ the "Press Ctrl-C to abort build, or Enter to continue" must be coming from something not those two scripts Jan 04 18:01:16 cause I just pasted a "exit 0" at the top of each of them Jan 04 18:01:18 and still get it Jan 04 18:01:32 yes thats an ugly design flaw in the debian f-k version Jan 04 18:02:00 ogra_: I'm using the Ubuntu f-k Jan 04 18:02:00 it tries to determine the root device from fstab and then puts it hardcoded into the initrd Jan 04 18:02:06 yes i know Jan 04 18:02:16 the ubuntu one is based on debians indeed Jan 04 18:02:22 Ahh. Jan 04 18:02:25 Any way around that message? Jan 04 18:02:29 but we work around such issues Jan 04 18:03:06 well, i dont really get why you still get the message Jan 04 18:03:32 theoreticallys thats not possible since flash-kernel should be completely omitted due to the env var Jan 04 18:04:00 so i assume debians keernel handling does something additionally that forcefullly runs flash-kernel Jan 04 18:04:27 iirc ages ago update-initramfs did the flash-kernel calll hardcoded Jan 04 18:04:41 but that was as i said ... ages ago Jan 04 18:05:09 grep flash-kernel /usr/sbin/update-initramfs Jan 04 18:05:12 ;) Jan 04 18:05:45 check if you are probably using such a version Jan 04 18:19:40 heh, funny CPU stresstest ... Jan 04 18:19:44 time echo "scale=4000; a(1)*4" | bc -l Jan 04 18:19:54 computes 4000 digits of pi Jan 04 18:20:55 seems the chromebook is only three times as slow as my core i5 3500k Jan 04 18:21:06 (5 times for the nexus7) Jan 04 18:39:24 does bc use all cores though? Jan 04 18:39:34 nope Jan 04 18:39:41 see #ubuntu-server :) Jan 04 18:40:06 seems panda and nexus7 are on par with that test Jan 04 18:40:20 so i'm pretty sure its single threaded Jan 04 21:23:16 real 0m9.965s Jan 04 21:23:20 on i7 Jan 05 00:02:22 Hi Jan 05 00:07:59 Anyone here able to troubleshoot Tegra 2 non-booting problems? Jan 05 00:16:58 Anyway, the tablet I'm trying to install Ubuntu onto is the Toshiba thrive. Biggest possible issue I see? The version of Tegra 2 it is. Jan 05 00:18:07 Is it a Harmony Tegra 2? Nope. Ventana? Nope. It's in its own ball park: the Antares. Jan 05 00:18:53 it's irrelevant. It's ventana based, but it doesn't really matter. THe drivers work on any tegra2 as long as it has the right kernel Jan 05 00:19:05 Hmm... Jan 05 00:20:43 Anyway, I'm hitting two things that are happening: Either it stays at the bootup logo, or the screen goes black, and the backlight goes off. Jan 05 00:21:01 I do get some garbled display on HDMI, either way. Jan 05 00:21:27 So, are there some essentials I need to have configured, besides VT and framebuffer console? Jan 05 00:22:23 what kernel are you using? Jan 05 00:25:19 I'm trying to build my own, as nobody has released one for the Thrive. However, what I'm starting to use is at this git: https://github.com/pio-masaki/at100-kernel Jan 05 00:25:30 *released a GNU kernel, that is. Jan 05 00:28:28 I do wonder if our ac100 kernels might Just Work on it. Jan 05 00:28:44 Compile for Ventana instead of Harmony? Jan 05 00:29:29 Both are Toshiba. That's good news. Jan 05 00:30:33 I've never seen a Thrive in person to play with it, but I'd always had a sneaking suspicion that (with the exception of a few peripherals) it's identical to the ac100. But, who knows. Jan 05 00:31:08 Heh. One of the Thrive devs would love to have an AC100. Can't afford it, though. Jan 05 00:31:14 If I were the Toshiba engineers, the ac100 would have just been my devel version of the at100 (cause keyboards are handy for debugging). Jan 05 00:31:46 Downloading AC100 kernel source. Jan 05 00:32:06 You could just grab the debs and try the binaries for a quick "hey, maybe this works" smoketest. Jan 05 00:32:24 I've prepared a rootfs on an external SD card already. Jan 05 00:33:17 It's actually a Plasma Active rootfs, but with my touch screen dying (cracked)... At least we have LXDE. Jan 05 00:34:07 Yeah... As nice as a VNC for Android solution is, it's extremely laggy, to the point of almost unusability. Jan 05 00:34:28 I've been seriously considering dropping Tegra2 support from future Ubuntu versions. If people are still actively developing on them, I may need to bring this to a community vote/discussion. Jan 05 00:36:10 Heh. The reason I chose the Thrive about a year ago was because it seemed to be a perfect candidate for Ubuntu. Jan 05 00:36:41 Yeah. And we've had a policy of no-neon-by-default specifically because of the Tegra2 (the only SoC we support that doesn't have NEON). Jan 05 00:37:09 It's irksome to keep patching upstream sources for this assumption, but if the target is still widely developed on/with, we may have to stick with it for a bit. Jan 05 00:38:59 Seems that performance development is slowly shifting away from x86 and going to ARM... Jan 05 00:39:54 About time. ARM could use more performance-oriented tweakers. Jan 05 00:40:40 I do like ARM because of its power-performance ratio. Jan 05 00:41:31 Yup, and that ratio can only improve as more people start hand-tuning code the same way they've done for x86, rather than falling back to generic C implementations. Jan 05 00:41:57 (But NEON is a big part of that story... hand-tuned NEON can be blazingly fast but, sadly, leaves Tegra2 out to dry) Jan 05 00:42:05 I'm no CPU design expert, but it seems that x86 is starting to hit a performance ceiling. Jan 05 00:42:21 Well, not all that sad. Just annoying that ARM allowed NEON to be optional so NVIDIA could make that silly decision. Jan 05 00:42:54 is this the right place to ask about what rooting option to choose from the google nexus 7 toolkit, to then install multrom and dualboot android and ubuntu?. if so wich rooting option should i choose, its a bit confusing. Jan 05 00:43:37 claes: https://wiki.ubuntu.com/Nexus7/Installation has clear unlocking instructions. Jan 05 00:44:00 claes: We don't support installing in a dual-boot setup, though, you're on your own for figuring that one out. Jan 05 00:44:25 ok thanks Jan 05 00:48:54 Well, porting Ubuntu Phone to a spare phone I've got should be fun... Jan 05 00:58:59 AmEv: can it run android stock kernel? that would be first step. Jan 05 00:59:26 It's actually a WebOS phone. Jan 05 00:59:52 Meets bare-minimum requirements, with OC... Jan 05 01:00:53 As for the Thrive, should I use the Google cross-compiler toolchain? Jan 05 01:02:43 Got a Ventana Android defconfig... Jan 05 01:02:54 And a Harmony GNU config.. Jan 05 01:04:41 Really? No Ventana GNU config on Google? Jan 05 01:05:25 Or is it under another name? Jan 05 01:14:41 Hmmm.. The one guy ported CM10 to the Thrive. Said that the Thrive was almost identical to the Iconia a500.... Jan 05 01:15:26 And it's a Harmony board.... Jan 05 01:17:53 AmEv: the Iconia a500 is a picaso board not a harmony board Jan 05 01:18:12 AmEv: Harmony is the name of one of the dev boards made by nvidia Jan 05 01:18:44 AmEv: but if you were to compare the device to a dev board it would be closer to ventana Jan 05 01:19:11 Hmmm... Jan 05 01:20:20 the a500 and the tf101 are almost identical, and the tf201 is almost identical in hardware and config to ventana (except the display) Jan 05 01:20:25 er Jan 05 01:20:30 s/tf201/tf101/ Jan 05 01:20:40 been doing too much work on the later one :p Jan 05 01:21:14 I know people have been runing Ubuntu on their Transformers for a while... Jan 05 01:21:24 Lemme see if I can snag the dev in here.... Jan 05 01:21:30 Nope. Jan 05 01:21:32 * lilstevie raises his hand Jan 05 01:22:03 http://forum.xda-developers.com/showthread.php?t=1191141 Jan 05 01:22:16 Heh. Jan 05 01:28:28 Yeah, I thought your name looked familiar from one of my earlier attempts. Jan 05 01:35:36 Hmmm... http://www.nvidia.com/content/devzone/linux-for-tegra.html Jan 05 01:44:34 Found a zImage, but no complimentary initfs... **** ENDING LOGGING AT Sat Jan 05 02:59:59 2013
