| angs | I have some boards that runs debian and some of them runs ubuntu. How can I understand which one is ubuntu and which one is debian? uname -a shows "Linux omap 3.2.0-psp7 #1 Fri Apr 13 04:55:05 UTC 2012 armv7l armv7l armv7l GNU/Linux" | 09:26 |
|---|---|---|
| rbasak | angs: on Ubuntu, "lsb_release -a" will tell you. I don't know if there's a better way. | 09:27 |
| angs | thanks a lot, it shows it is ubuntu:) | 09:27 |

| djszapi | ogra_: hey | 11:15 |
| djszapi | ogra_: gpio library is not available for Ubuntu arm ? :o | 11:16 |
| djszapi | perhaps it is the sysfs that is advertised for usage nowadays. | 11:18 |
| janimo | lilstevie, do you know if there are git trees of tf101 kernels with better history and changes rationale than what ASUS' tarballs provide? | 13:13 |
| lilstevie | janimo, yes/no | 13:13 |
| janimo | lilstevie, please expand on the yes branch :) | 13:13 |
| * janimo figures this is an interactive adventure | 13:14 | |
| lilstevie | janimo, we can match to where they most likely branched from nvidias tree | 13:14 |
| lilstevie | with their history | 13:14 |
| lilstevie | but asus themselves strip *ALL* history before releasing it | 13:14 |
| janimo | lilstevie, that is what I was going to check, seeing only it is a 2.6.39.4 | 13:15 |
| janimo | but compared to upstream pristine linux-stable 2.6.39.4 there | 13:15 |
| janimo | is a 15Mb patch :) | 13:15 |
| lilstevie | yeah, well matches with nvidias android tree | 13:15 |
| lilstevie | look at androids 2.6.39.4 | 13:15 |
| lilstevie | it is a pain though | 13:15 |
| lilstevie | cause there are a few tags | 13:15 |
| lilstevie | RaYmAn has a script which diffs each tag against the asus release and suggests the closest match | 13:16 |
| lilstevie | we have done it to the tf201, tf101 is next on the list to be moved over to nvtegra | 13:17 |
| janimo | lilstevie, by moved over to nvtegra and 'we' what do you mean? Kernels used by the mod community? | 14:17 |
| lilstevie | androidroot team, me bumble-bee RaYmAn kmdm and IEF | 14:44 |
| lilstevie | janimo, ^^ | 14:44 |
| janimo | lilstevie, ok | 14:47 |
| xase_ | I cant believe theres no tutorials for running ubuntu on nookcolor besides that silly chroot nonsense. | 16:34 |
| prpplague | hehe | 16:39 |

| GrueMaster | xase_: I was going to work on that for Oneiric, but was swamped with the arm server bringup. Sadly, I have since moved on to a differnt job (and subsequentially lost time/interest). Sorry. | 17:20 |
| xase_ | GrueMaster: no problem do you have an archive of your work available? | 17:51 |
| GrueMaster | No. I didn't get too far into it. I barely spent a week on it, mainly going through the Nook source and seeing what I needed to implement. | 17:53 |
| xase_ | damn | 17:56 |
| janimo | marvin24, are you working more on nvec until it gets out of staging? | 19:17 |
| marvin24_DT | janimo: yep | 19:21 |
| janimo | marvin24, do you have the docs from nvidia? | 19:22 |
| marvin24_DT | yes | 19:22 |
| janimo | the README in the tree suggests there are no docs at all | 19:22 |
| marvin24_DT | oh, that deserves a patch ;-) | 19:22 |
| marvin24_DT | in fact, I "appeared" some month ago | 19:23 |
| janimo | ok, just making sure you're not missing out :) I just discovered they're public last week, and downloaded them today | 19:23 |
| marvin24_DT | together with the tegra2/3 documentation | 19:23 |
| janimo | yes, Nov 11 from what I saw | 19:23 |
| marvin24_DT | janimo: public? | 19:23 |
| janimo | ah tegra3 as well? I thought that's still WIP | 19:23 |
| marvin24_DT | you need to register first ... | 19:23 |
| janimo | well, public with annoyance, but not private/NDA etc :) | 19:24 |
| marvin24_DT | mmh, I think there is a NDA at least, but I didn't read it to the end | 19:24 |
| janimo | marvin24, so this means the EC doc that was floating around of the chip used in the ac100 is not necessary, as you only need the tegra2 side/protocol | 19:25 |
| janimo | ah did not read either :) | 19:25 |
| marvin24_DT | mmh, I don't know of any EC doc floating around ... wait | 19:26 |
| marvin24_DT | ah, found it | 19:27 |
| marvin24_DT | of course, for this has no NDA ;-) | 19:31 |
| marvin24_DT | normally, you would have to register here http://developer.nvidia.com/tegra-2-technical-reference-manual | 19:31 |
| janimo | yes, I registered and downloaded this and the TRM today | 19:42 |
| janimo | there was an EC doc for an embedded keyboard controller in the ac100 last year | 19:42 |
| janimo | which I was told was the only doc that helped the nvec initial development | 19:42 |
| marvin24_DT | maybe that was the original source | 19:42 |
| marvin24_DT | it had some documentation inside | 19:43 |
| marvin24_DT | janimo: can you try to get linux-backports-modules-cw-3.3-precise-generic building on ARM ? | 19:46 |
| janimo | is that a package? | 19:46 |
| marvin24_DT | eh, no, the binary | 19:46 |
| marvin24_DT | wait ... | 19:46 |
| janimo | found it | 19:46 |
| janimo | but it's for the 3.2.0 precise kernel | 19:47 |
| marvin24_DT | linux-meta is the source :-( | 19:47 |
| marvin24_DT | should be buildable on any kernel | 19:47 |
| janimo | not even amd64 is enabled | 19:47 |
| marvin24_DT | I have it here on my amd64 ... | 19:48 |
| marvin24_DT | https://launchpad.net/ubuntu/precise/amd64/linux-backports-modules-cw-3.3-precise-generic | 19:48 |
| janimo | ok, so Architecture: is misleading | 19:48 |
| janimo | linux-backports-modules-3.2.0 the package | 19:49 |
| janimo | marvin24, which drivers are needed on arm? | 19:49 |
| marvin24_DT | I don't know, but paz00 needs rt2xx | 19:50 |
| marvin24_DT | I think they can also be useful for panda whatever | 19:50 |
| marvin24_DT | the package contains all wifi drivers | 19:52 |
| marvin24_DT | btw, I still can only get a 3.1 kernel booting with "console=ttyS0,115200n8 quiet" enabled | 19:54 |
| marvin24_DT | this ensures nothing it printed to the console on boot | 19:54 |
| janimo | so not yet ready for uploading I guess? Any chance of newer kernels being better? | 19:55 |
| janimo | how much of what's working now is not yet ported to 3.5? | 19:55 |
| marvin24_DT | everything gpu and power save related is missing | 20:13 |
| marvin24_DT | (which is too important to be skipped) | 20:13 |
| janimo | marvin24, are the changes in 3.5 too big so that code need significant rewrite? | 20:13 |
| janimo | I see nvidia devs steadily sending patches upstream | 20:14 |
| marvin24_DT | yeah, still unportable I think | 20:14 |
| marvin24_DT | there are lots of nv engineers already working on it | 20:14 |
| marvin24_DT | but it takes time | 20:14 |
| marvin24_DT | somehow nv decided to rewrite everything at least three times | 20:15 |
| marvin24_DT | this is the price you have to pay to get a product quickly to market | 20:15 |
| marvin24_DT | you just cannot do it in a sane way | 20:16 |
| marvin24_DT | and mainlining is only low priority compared to that | 20:16 |
| marvin24_DT | I don't want to know how many developers worked on porting win8 to tegra3 | 20:17 |
| marvin24_DT | and even less I want to see that code | 20:18 |
| janimo | :) | 20:18 |
| janimo | in that case they may not rewrite at all as there's no mainlining required ever, and win8 will be around for many years | 20:19 |
| janimo | maybe it's only the FOSS model that gives grief to developers. Or at least this type of grief | 20:19 |
| marvin24_DT | I would be interested in some kind of statistics how much developer month it takes to port some arch to linux and windows | 20:21 |
| marvin24_DT | and how much time it consumes to maintain it | 20:21 |
| marvin24_DT | during product lifetime | 20:21 |
