| mssbrg | Hi, I'm trying to download the source for a 3.17.8-031708-generic ubuntu kernel (running on a 14.10 system) but I'm having trouble | 01:29 |
|---|---|---|
| mssbrg | apt-get source always seems to download a 3.16 kernel, and I don't see tags for 3.17 in the ubuntu/ubuntu-utopic git | 01:30 |
| tmpRAOF | mssbrg: You've got that 3.17 kernel from the kernel “PPA”; that's not an official Ubuntu kernel. | 01:37 |
| tmpRAOF | mssbrg: If you want the source package you'll need to reconstruct it from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.17.8-vivid/; COMMIT tells you the upstream commit, plus the 000?-*.patch files. | 01:39 |
| infinity | mssbrg: And, to be fair, you really should never run those kernels except for testing, they're not in any way supported (or supportable). | 01:55 |
| infinity | Nor are they tested in any way. | 01:56 |
| mssbrg | O_O | 01:57 |
| mssbrg | oh jeez. i never knew | 01:57 |
| mssbrg | infinity: i guess i don't really understand why they exist or are available then? | 02:01 |
| infinity | mssbrg: They're really just there to be able to test upstream kernels quickly as a coarse pre-bisection "does this work here?" tool. | 02:33 |
| mssbrg | infinity: Ok. So if kernel.ubuntu.com/~kernel-ppa isn't a good place to get kernels, what is the recommended place? kernel.ubuntu.com/git? | 02:35 |
| tmpRAOF | mssbrg: The recommended place to get kernels is “apt install linux-generic” :) | 03:15 |
| tmpRAOF | mssbrg: On 14.04 we also do backports of the latest release's kernel (+ X stack) for hardware-enablement purposes. | 03:17 |
| mssbrg | tmpRAOF: sort of confused now because "apt search linux-generic" lists the linux-image-3.17.8-031708-generic kernel (currently installed) which infinity told me I shouldn't run? | 03:35 |
| tmpRAOF | mssbrg: apt show linux-generic | 03:35 |
| tmpRAOF | The “linux-generic” package is a metapackage that depends on the latest version of the official kernel. | 03:36 |
| mssbrg | ah | 03:37 |
| mssbrg | tmpRAOF: I also just realized I'm running a vivid kernel on utopic...is that bad? did I just get lucky that things seemed to work? | 05:21 |
| tmpRAOF | mssbrg: The kernel version is not particularly important, as long as it supports your hardware. | 05:23 |
| mssbrg | tmpRAOF: interesting. also a follow up ques on what you said earlier ("that's not an official Ubuntu kernel"): if that wasn't an official kernel, is it right to think that the git tags of the form "Ubuntu-3.xx.xx-etc" are the official ones? | 05:29 |
| mssbrg | and the tags that are just vx.y.z are the regular mainline versions? | 05:29 |
| tmpRAOF | mssbrg: The (source of the) official Ubuntu kernel is what you get when you run apt-get source linux-image-3.xx-yy-generic :) | 05:31 |
| mssbrg | (sorry I have so many questions) | 05:37 |
| mssbrg | 1. apt-get source always seems to download 3.16 for me. is there any way to force it download a 3.17+ kernel? or does that mean there are no official 3.17+ kernels for 14.10? | 05:38 |
| tmpRAOF | There are no official 3.17+ kernels for 14.10 | 05:38 |
| mssbrg | 2. and from a git perspective was I correct about Ubuntu tags == official? or is there any way to tell what is official or not from git? | 05:39 |
| tmpRAOF | Yeah, the official kernels are built from those git tags. | 05:40 |
| mssbrg | thanks tmpRAOF! :) | 05:54 |
| apw | jibel, hey ... trusty proposed-migration, the kernel autopkgtests show as Test in progress, and yet to my eye they are both complete, i suspect some kind of disconnect | 11:23 |
| apw | jibel, and ... morning :) | 11:23 |
| jibel | apw, good* morning :) | 11:26 |
| apw | :) i like good mornings | 11:26 |
| jibel | apw, well it was good until now. I'll have a look | 11:26 |

| yggdrasi1 | bletooth module hci_uart, cdc-acm, btusb, rfcomm loaded | 14:33 |
| yggdrasi1 | but i didn't fire up th ACM0 tty | 14:34 |
| yggdrasi1 | is it an issue with the cdc_acm driver? | 14:34 |
| yggdrasi1 | also try to force this using modprobe cdc-acm but still the same | 14:35 |
| yggdrasi1 | also used the usbserial but not so much more result | 14:35 |
| yggdrasi1 | did one have an idea of my problem. What I want to do is to hciattach this dongle | 14:36 |

| tohoyn | ubuntu with kernel version 4.0.0-040000rc1 fails to shutdown | 17:30 |
| tohoyn | is here some meeting ongoing? | 17:31 |
| ogra_ | no, thats usually in #ubuntu-meeting | 17:32 |
| ogra_ | (but i think they are done) | 17:32 |
| tohoyn | ogra_: did you see my message about shutdown failures? | 17:34 |
| ogra_ | yeah, i'm no kernel dev ... | 17:35 |
| apw | tohoyn, that is an -rc1 so i am not supprised | 17:35 |
| ogra_ | and it has a scary amount of zeros in the minor version :) | 17:35 |
| mssbrg | can anyone explain to me the format used for tags in the ubuntu kernel trees? for example: Ubuntu-3.18.0-10.11 | 17:49 |
| mssbrg | I can see that the upstream version number always seems to be held at .0 and then it seems like the other two numbers refer to updates being pulled from upstream? | 17:51 |
| apw | mssbrg, yes, we would like to call it 3.18-10.11, but some of usespace gets all snarky | 17:54 |
| apw | so ignore the .0 and then -10 is the ABI number, and .11 is the upload number | 17:54 |
| === jsalisbury changed the topic of #ubuntu-kernel to: Home: https://wiki.ubuntu.com/Kernel/ || Ubuntu Kernel Team Meeting - Tues March 3rd, 2015 - 17:00 UTC || If you have a question just ask, and do wait around for an answer! If the question is should I file a bug for something, likely you can assume yes. | ||
| mssbrg | apw: I think I understand, but I'm not familiar with ABI/upload numbers :/ To rephrase, for the mainline v3.18.7 kernel for example, where does the .7 go/what is the corresponding ubuntu tag? | 18:05 |
| apw | mssbrg, it does not go anywhere, it will be inside one of the ABIs if it is applied | 18:05 |
| apw | you can tell from the running system what base version it really is in /proc/version_signature | 18:06 |
| fossterer | Hello kernel team! Can I get sources for the kernel I downloaded from http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33.6-maverick/ ? | 20:18 |
| fossterer | The source... deb there is empty! | 20:19 |

| === offline is now known as mssbrg | ||
| infinity | fossterer: The source is in git. | 20:25 |
| infinity | apw: What's the magic to translate mainline builds into git repo/tags so people can actually hunt down the source? | 20:26 |
| fossterer | infinity: Here? http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33.6-maverick/ | 20:28 |
| fossterer | !git | 20:30 |
| ubot5 | git is a distributed revision control/software code management project created by Linus Torvalds. For more information, see http://en.wikipedia.org/wiki/Git_(software) | 20:30 |
| fossterer | !kernel | 20:30 |
| ubot5 | The core of Ubuntu is the Linux kernel: see https://help.ubuntu.com/community/Kernel - You shouldn't have to compile your own, and if you need to troubleshoot issues, you can try a !Mainline kernel instead, but if you insist, see https://help.ubuntu.com/community/Kernel/Compile (see also !Stages) | 20:30 |
| fossterer | I get hits for 2.6.32 as well as 2.6.34.. Where do I find 2.6.33 ? | 20:35 |
| fossterer | Help ^^ | 20:35 |
| fossterer | I am looking here: http://kernel.ubuntu.com/git | 20:35 |
| infinity | fossterer: I would guess ubuntu-archive/ubuntu-maverick.git, or the 2.6.33.6 tag in linus's tree upstream, but I'm not positive, hence why I asked apw for input. Be patient. | 20:37 |
| infinity | fossterer: But a more curious question, WHY?! Why do you want an ancient unsupported kernel? :P | 20:37 |
| fossterer | Ohh.. Thanks.. I'll be here | 20:37 |
| === _ruben_ is now known as _ruben | ||
| fossterer | infinity: Sorry, I was away... | 21:14 |
| fossterer | infinity: I have a few patches to be applied to 2.6.33.6 kernel to make it work with 802.11p | 21:15 |
| apw | fossterer (N,BFTL), there is no source package for the mainline builds, they are built from virgin upstream sources, the COMMIT file contains the linus tag/commit they are built from and the patches therein ????-* are applied on top to make the source | 22:14 |
| apw | infinity, ^ incase he asks again | 22:15 |
| mssbrg | out of curiousity, if the idea for those mainline builds to to have a virgin upstream build, then what are the patches for? | 22:35 |
| mssbrg | *is to | 22:35 |
| infinity | apw: Given that they're producing binary packages, it might be nice to produce a matching source package so people don't ask questions. Or, at least, have the top of the build log explicitly state what to clone, what to checkout, and what to add to make it go. | 22:40 |
| infinity | apw: But, in that guy's case, I'm less fussed about GPL compliance and more still very confused by why he cares about 2.6.33 | 22:41 |
