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