**** BEGIN LOGGING AT Sun Jul 29 02:59:59 2012 Jul 29 09:46:43 I'm trying to use the netinstall method on a beagleboiard Jul 29 09:46:51 getting an error: no kernel modules found Jul 29 12:22:11 anyone running ubuntu on a tegra3 tablet? Jul 29 12:39:26 noone? Jul 29 12:49:12 janrinze2: better ask during workdays Jul 29 12:50:26 marvin24: somehow this is ubuntu-arm but most people here talk about old dev boards like the beagleboard Jul 29 12:50:44 janrinze2: because that is what ubuntu supports Jul 29 12:51:03 panda is supported too Jul 29 12:51:04 unsupported device have normally their own channels Jul 29 12:51:58 hm.. i am typing this from a tablet running ubuntu but it is a tegra 2 Jul 29 12:52:14 janrinze2: you first need a kernel Jul 29 12:52:43 I think tegra3 already ships with a 3.1 kernel, so ... Jul 29 12:52:55 true, and asus for example has given sources for that kernel Jul 29 12:53:07 ... what's the problem? Jul 29 12:53:54 i want to know which tablet to buy, i am not willing to buy 4 and figure out which one suis best ;-) Jul 29 12:54:19 well, I woudn't install ubuntu on a tablet at all Jul 29 12:54:35 beside that, I wouldn't buy one Jul 29 12:54:45 because I fail to see the use of it Jul 29 12:55:04 marvin24: technically the asus tablets are more ike a laptop/tablet combo Jul 29 12:55:22 ah, you mean the one with a keyboard dock Jul 29 12:55:27 yep Jul 29 12:55:36 ok, maybe that's something different Jul 29 12:56:08 i have a first generation one, which runs ubuntu and i am typing on it now :-) Jul 29 12:56:21 the tf301 is widely used, so there is hope for good support from the community Jul 29 12:56:50 tf301? i thought it was the tf300t Jul 29 12:57:20 whatever - I can't remember so many numbers Jul 29 12:57:29 no prob. :-) Jul 29 12:57:54 on the other hand, nvidia's support for oss hackers isn't well Jul 29 12:57:56 i want at least quad core and NEON support Jul 29 12:58:14 maybe a snapdraggon or omap would be better Jul 29 12:58:23 they also have faster cpus/gpus Jul 29 12:58:28 perhaps the omap4 types from archos? Jul 29 12:59:05 no idea, I'm fine with my tegra2 netboot ;-) Jul 29 12:59:11 *netbook Jul 29 12:59:23 i already have 6 dev boards laying around : exynos, panda, snowball, beagle .. Jul 29 12:59:45 marvin24: ac100 ? Jul 29 12:59:50 yep Jul 29 13:00:15 quite similar to the tf100 Jul 29 13:01:30 no NEON though Jul 29 13:01:48 why do you need NEON? Jul 29 13:02:14 it is a lot faster than vfp Jul 29 13:02:26 is can do simd too Jul 29 13:03:17 there is not so much fp code that it would make a big difference Jul 29 13:03:21 at least for comman apps Jul 29 13:03:56 i do graphical apps, think photo editing Jul 29 13:04:12 that needs a huge amount of fp Jul 29 13:04:37 ... and memory and cpu power Jul 29 13:04:46 both don't exist on ARM yet Jul 29 13:05:59 i have done some tests on both omap 4 , nova A9500 and exynos 4, they all have NEON and do some serious number crunching Jul 29 13:07:21 so going quad core i hope to see usable speed with raw conversion and filters Jul 29 13:08:33 on tegra 2 the results are a lot slower than on omap or exynos Jul 29 13:10:35 most distros build in thumb mode which makes small binaries but slow performance. i usually build with -marm -mfpu=neon to get much more performance Jul 29 13:29:53 janrinze2, marvin24: TBH Ubuntu on Tegra2 is currently laughable Jul 29 13:30:13 Well, you can easily install it and boot it but it's terribly slow Jul 29 13:30:27 Also you will not get decent hw acceleration any time soon I believe Jul 29 13:31:02 Uh, by the way, if you want any hardware acceleration at all you have to use u-boot which is well, quite unstable now Jul 29 13:31:12 i.e. doesn't work for everyone Jul 29 13:31:52 Apparently the video drivers for ac100 should work on tf101 too but they don't because the tf101 kernel lack some interfaces as far as I can remember Jul 29 13:32:13 I doubt it will get any better with Tegra3 unless NVidia decides to provide more support Jul 29 13:34:34 Quintasan: so omap 4 or snapdragon then? Jul 29 13:35:06 *shrug* I'm no expert at all. Jul 29 13:35:11 I'd go with omap4 Jul 29 13:35:17 snapdragon is htc thing? Jul 29 13:35:22 janrinze2, I am running ubuntu on a tegra3 Jul 29 13:35:39 lilstevie: which platform? Jul 29 13:36:35 tf201 Jul 29 13:36:59 lilstevie: native or in chroot? Jul 29 13:37:15 does chroot even count? Jul 29 13:37:22 lilstevie: You have the newer tf? Jul 29 13:37:28 nope not really ;-) Jul 29 13:37:44 tbh I would have thought you would have recognised the nickname if you are running ubuntu on the tf101 janrinze2 Jul 29 13:37:46 :p Jul 29 13:37:56 Quintasan, yes, I have had for a while Jul 29 13:38:18 Is it just me finding Ubuntu on tf101 unbearably slow or I'm doing something wrong? Jul 29 13:38:24 lilstevie: i thought you ran on the tf101 too Jul 29 13:38:30 janrinze2, I do Jul 29 13:38:33 I have both Jul 29 13:38:55 Quintasan, yes, main reason my tf101 hasn't been charged in like a month or 3 Jul 29 13:38:56 ok, and tf300 or tf700? doable? Jul 29 13:39:06 probably Jul 29 13:39:41 lilstevie: Is this slowness caused by kernel or lack of hardware acceleration on things? Jul 29 13:39:58 it is just the lacklustre performance of tegra in general Jul 29 13:40:21 lilstevie: and tegra 3 is that a lot better? Jul 29 13:40:57 eh Jul 29 13:40:59 better Jul 29 13:41:11 a lot better would be stretching things Jul 29 13:41:16 nvidias driver is balls Jul 29 13:41:42 As I thought Jul 29 13:41:59 janrinze2: Don't tell me you find the performance on tf101 satisfactory Jul 29 13:42:30 For life of me I couldn't use that for longer than 20 minutes Jul 29 13:42:53 Quintasan: try compiling with -marm and see a 20 - 40 % improvement in speed with a lot of code Jul 29 13:43:14 I'm asking about desktop performance Jul 29 13:43:21 like dragging windows Jul 29 13:43:46 compositors Jul 29 13:43:47 etc Jul 29 13:44:54 dragging windows is not a big deal, it depends on the windowmanager. try lxde Jul 29 13:45:33 just don't try to use compiz ;-) Jul 29 13:46:16 I'm not sure I have the nerve to compile all that stuff Jul 29 13:46:27 I have been trying to get Debian running on my imx53 board Jul 29 13:46:33 Can't say I got it working Jul 29 13:47:33 i read that there are ARM SoC boards upcoming with a lot of improved memory bandwidth to fix the speed issues Jul 29 13:48:11 Quintasan: imx53 is cortex A8 right? 1GB or less mem? Jul 29 13:48:27 1GB DDR3 Jul 29 13:48:52 DDR3 so 16 bit interface to the SoC? Jul 29 13:49:33 64 bit DDR3 is upcoming soon for ARM boards, i read Jul 29 13:49:36 probably Jul 29 13:49:52 I don't recommend this board at all Jul 29 13:49:55 that would increase bandwidth by 4x Jul 29 13:50:38 on the ac100, the main limiting issue is the mmc speed Jul 29 13:50:42 Quintasan: imx53 board is in general a bit slower than beagle board Jul 29 13:51:01 the cpu idles most of the time Jul 29 13:51:04 marvin24: mmc speed is slow too, indeed Jul 29 13:51:10 janrinze2: IDC really, I want a bare Debian system with ssh server and rtorrent for now Jul 29 13:51:47 and the numbers of ARM SoCs with SATA isn't high ... Jul 29 13:51:54 Quintasan: try panda or exynos, those will do fine as bare Debian Jul 29 13:52:01 on fact, tegra has sata and even pcie Jul 29 13:52:10 I don't have the money though Jul 29 13:52:15 but no board mfg uses it Jul 29 13:52:38 likeley for power consumption reasons Jul 29 13:52:44 marvin24: the only board with sata on tegra 3 is more costly than my PC Jul 29 13:54:20 mass production ... Jul 29 13:54:35 the target market are tablets (with android) and smartphones Jul 29 13:54:57 for them it is enough and a good compromise Jul 29 13:55:15 if you want more powerconsumptions, wait for A15 SoCs Jul 29 13:59:54 marvin24: waiting for the next gen is always possible. however in the mean time what will you do? oh, and there will be newer stuff announced by then.. would you then wait again? Jul 29 14:01:28 i have been working on ARM platforms for 20+ years and these new systems are a lot faster than what i used to have. Jul 29 14:01:48 janrinze2: but maybe not what you want ... Jul 29 14:02:11 a intel core cpu is a lot more efficient (and cheeper) than an arm Jul 29 14:02:54 at least when it comes to "photo editing" Jul 29 14:03:12 marvin24: not at all!! remember that efficiency is a function of performance versus energy consumption Jul 29 14:03:26 exactly Jul 29 14:03:45 so intel core is a lot less efficient Jul 29 14:03:50 no Jul 29 14:03:54 yes Jul 29 14:04:01 do the math Jul 29 14:04:10 do you have benchmark numbers? Jul 29 14:04:56 and atoms are not core i's Jul 29 14:05:05 atom is also very bad efficient Jul 29 14:05:27 true, but core eats up a lot of power Jul 29 14:06:05 marvin24, tegra3 has sata* Jul 29 14:06:18 the 1GB limit for devices is a more restricting issue than the cpu power Jul 29 14:06:21 marvin24, tegra2 does not and the pcie is in relaxed ordering mode Jul 29 14:07:13 lilstevie: right, tegra2 hasn't sata Jul 29 14:07:18 correct Jul 29 14:07:43 with 2GB or more fast memory quad core ARM systems would be similar to intel core in performance Jul 29 14:08:24 remember that this is on a same speed 1GHz setting Jul 29 14:09:24 due to slow LPDDR many ARM boards perform not so well Jul 29 14:10:19 but it still fits a few watts of power envelope Jul 29 14:16:26 lilstevie: i plan to donate the tf101 to a friend and buy a tf300 or something with a bit more power Jul 29 14:18:13 lilstevie: i want to be able to run ubuntu or debian since i mainly will be using it for testing software Jul 29 14:20:18 lilstevie: any suggestions? Jul 29 14:22:16 honestly, don't let me influence your decision, but I only have a tf201 Jul 29 14:22:30 other than the tf101 ofc Jul 29 14:43:52 so ubuntu finished the installtion process on my beagleboard Jul 29 14:44:02 now its not starting Jul 29 14:44:13 on 'boot' all I see is "60" printed on serial Jul 29 14:44:28 Any one know why ubuntu for arm on the beagleboard XM I connect it to my TV it says resolution not supported Jul 29 14:44:49 aaron: what resolution is your BB set to? Jul 29 14:45:11 I don't know. How would I set it. Jul 29 14:45:54 I followed the instructions on the web site to install it to a SD card? Jul 29 14:46:00 hmmm http://markmail.org/message/fi6pzmm3rrzbft7e#query:+page:1+mid:n56r7yppkx4vgrf6+state:results Jul 29 14:53:04 Is it because I'm using a HDMI -> HDMI cable? Should I really be using a DVI -> HDMI cable? Jul 29 14:58:23 aaron: hdmi to hdmi is fine Jul 29 14:59:01 I followed method 2 on the elinux wiki (net install): the sd card after installation doesn't seem to have the geometery normally required.... Jul 29 14:59:13 I assume theres a faault in the partitioning? Jul 29 15:00:15 I followed the instructions on the Ubuntu web site? using the dd command Jul 29 15:49:35 ubuntu is not yet stale on this device :-( Jul 29 15:49:41 had to reboot Jul 29 15:50:23 hmm stale>stable Jul 29 16:11:37 what device? Jul 29 16:48:22 RoyK: tf100t Jul 29 16:50:09 beagleboard XM **** ENDING LOGGING AT Mon Jul 30 02:59:58 2012
