| Matsy | Ah, this seems to be a more suitable channel for my question. I am in need to install the 2.6.32.9 kernel. I just need it to compile a certain kernel driver. How would I go and do such a thing? I'm currently doing a git sync of kernel.org, but I doubt I will be able to see the previous versions there. | 09:13 |
| apw | Matsy, the 4 number versions are not in linus' tree, they are in the stable trees. we do produce unsupported builds of them however | 09:15 |
| apw | https://wiki.ubuntu.com/Kernel/MainlineBuilds | 09:15 |
| Matsy | Hm, okay. I can see it right there. I'm on 10.04 right now. Would I also need the -lucid package from the repository? | 09:17 |
| apw | yep | 09:18 |
| Matsy | Interesting enough, then! | 09:23 |
| Matsy | Oh, gah. Need to resize my virtual disk first. I knew I shouldn't have picked 18GB | 09:26 |
| lacostej | I reported, tracked and got kernel regression https://bugs.launchpad.net/ubuntu/+source/linux/+bug/86820 fixed upstream. It will only appear in 2.6.36. Any change we can backport this in 10.10's kernel ? I'am tired of backporting the change in my 10.04 custom kernels... Tanks | 10:03 |
| ubot2 | Launchpad bug 86820 in linux-source-2.6.20 (Ubuntu) (and 1 other project) "touchpad doesn't work after suspend (affects: 2) (dups: 2) (heat: 41)" [Medium,Won't fix] | 10:03 |
| ikepanhc | if we need to give some parameter to one module, can we write the parameter somewhere in /etc? | 10:39 |
| === diwic_ is now known as diwic | ||
| apw | ikepanhc, yep, /etc/moprobe.d/<newfile> | 10:43 |
| ikepanhc | eh... | 10:44 |
| ikepanhc | add file for myself? | 10:44 |
| ikepanhc | oh, I see it, write options there | 10:45 |
| === amitk is now known as amitk-afk | ||
| ikepanhc | apw: thanks | 10:45 |
| apw | yeah you can make new files in there for your purpose | 10:52 |
| Matsy | Hm. | 10:57 |
| Matsy | Okay, the installation of 2.6.32.9 didn't quite work. :( | 10:58 |
| Matsy | Or at least, it's not giving me the result I would like. | 10:58 |
| Matsy | Apparently, it's saying: Kernel configuration is invalid, autoconf.h and auto.conf are missing. Run make olconfig && make prepare to fix it. | 10:59 |
| Matsy | But, those return 'error 2' | 10:59 |
| Matsy | So I'm not quite sure what to do here. | 11:00 |
| Matsy | The error the command make oldconfig && make prepare is giving me is as follows: make: *** No rule to make target `include/config/auto.conf', needed by `include/config/kernel.release'. Stop. | 11:02 |
| === diwic is now known as diwic_afk | ||
| Matsy | Any ideas? | 11:03 |
| Matsy | Oh, I managed to do it. Now, it's saying it cannot find modpost. Hm. | 11:09 |
| apw | Matsy, sorry not ever tried to build a module against those | 11:15 |
| Matsy | apw: Aw, thanks though. I'll just keep on trying. | 11:16 |
| Matsy | Oh no. | 11:18 |
| Matsy | I need 2.6.34.5 | 11:18 |
| Matsy | Darn. | 11:18 |
| Matsy | Flawed information is always nice. | 11:19 |
| apw | at least that version is also in the archive | 11:19 |
| Matsy | Yeah, that's true. | 11:21 |
| Matsy | But, no sources available, apparently? | 11:21 |
| Matsy | Gah, this is too complicated. | 11:30 |
| === amitk-afk is now known as amitk | ||
| Matsy | I might be doing it very much wrong. | 11:34 |
| Matsy | All I want to do is download the 2.6.34.5 kernel, and compile it. | 11:34 |
| Matsy | Oh, gconfig did the job. | 11:45 |
| * apw wonders why you need that specific version | 11:49 | |

| dionys | hi | 11:50 |
| apw | hi | 11:52 |
| dionys | having Ubuntu 10 - I'm running a very time critical task - how can I boot into no-Xwindows and give 99% scheduling to a single task? | 11:56 |
| dionys | I managed to compile rt/smp and set the highest rt priority for the task but it still gets interrupted too much | 11:58 |
| dionys | maybe the answer is running DOS but there must be a way to get linux into doing a single task apart from the kernel | 12:01 |
| dionys | booted into recovery root console does work for now | 12:17 |
| apw | dionys, how are you determining it is interrupted too much | 12:18 |
| apw | and what is your latency requirement ? | 12:18 |
| apw | thinks truly running at RT priority should be able to break the system by starving it of CPU | 12:19 |
| ogra | for x-less boot you just need to put "text" on the kernel cmdline btw | 12:20 |
| dionys | sorry I was away for lunch | 12:49 |
| dionys | as it appears I need to have 20micro seconds | 12:51 |
| dionys | if a program does a sleep(x) does the kernel come back after x or after x plus the time spend in other tasks? | 12:52 |
| dionys | I guess after experiencing these interrupts the kernel comes back after x plus the time spend on other tasks | 12:57 |
| dionys | apw: I determined the interruption by causing CPU load by moving windows and then experiencing more hickups to the program I'm running | 13:04 |
| apw | dionys, there is some jitter on how long later it comes back based on the scheduler, you would expect an RT process to have a lower latency there though as it is much higher priority | 13:05 |
| dionys | as I mentioned by running in a terminal window in recovery mode has taken away the interruptions | 13:09 |
| Matsy | Hm. | 13:10 |
| Matsy | Compiling the kernel is taking a long time. Are there any flags I can set to speed it up? I'm on a quad core system. | 13:10 |
| dionys | Matsy: a solution would be the break down the compiles into independent work units and give them to one workertask per core - which I don't think is implemented | 13:14 |
| Matsy | Hm. | 13:14 |
| Matsy | What'd the general compilation time be of a Linux kernel? | 13:15 |
| Matsy | On a Q6600 / 4GB ram | 13:16 |
| dionys | not the quantity of the ram is essential here but the ram timings | 13:16 |
| abogani | Matsy: -j8? | 13:18 |
| dionys | but maybe there is a way to make build units run in parallel on each core | 13:18 |
| Matsy | Oh | 13:20 |
| Matsy | Haha, thanks abogani | 13:20 |
| abogani | Matsy: You are welcome. | 13:21 |
| Matsy | Hm. | 13:22 |
| Matsy | I am building a kernel module | 13:22 |
| Matsy | But, when I try to load it, it can't load, saying Exec format error. | 13:22 |
| Matsy | I'm fairly certain that I am building it against the right kernel | 13:22 |
| Matsy | But, I am not quite sure what the error means | 13:22 |
| Matsy | Could it be because I am compiling it on a 64 bit machine, and that it is going to run on a 32 bit machine? | 13:23 |
| apw | Matsy, yes you need to build it in the right environment | 13:31 |
| apw | often that is a chroot with a 32 bit install in it | 13:31 |
| Matsy | hm. | 13:33 |
| Matsy | I can't use -m32 to build it?\ | 13:33 |
| apw | you may be able, it wouldn't be guarenteed to be the same exact kernel as woudl be built in an chroot though | 13:36 |
| apw | Matsy, which kernel are you loading this module into btw ? | 13:36 |
| apw | as modules need to built against the kernel they are loaded into | 13:37 |
| Matsy | A custom kernel, it's a smartphone kernel. | 13:37 |
| Matsy | Makefile is pointing to the source of that one kernel. | 13:37 |
| Matsy | My phone is in sync with that kernel. | 13:38 |
| Matsy | But, when I try and do insmod module.ko, it presents me with that errors. | 13:38 |
| Matsy | *error | 13:38 |
| apw | you often need the same compiler they used to build the kernel too | 13:38 |
| Matsy | Same.. compiler as well? | 13:39 |
| Matsy | Hm. | 13:39 |
| apw | you do for an ubuntu kernel | 13:39 |
| Matsy | I don't know if they're included, let me see. | 13:39 |
| Matsy | Nope, no compilers included. | 13:41 |
| Matsy | Can't I force load this in any way? | 13:41 |
| abogani | Matsy: Don't you can ask to people have done that smartphone kernel? :-) | 13:43 |
| Matsy | No one has done this before, apparently. | 13:43 |
| Matsy | So it's a bit tricky ;) | 13:43 |
| Matsy | If I'm being a pain for asking here, please tell me, and I'll just look somewhere else. | 13:44 |
| Matsy | I will try #android-dev, though. Might be a bit more relevant indeed. | 13:45 |

| sidnei | hi folks, is anyone aware or working on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/524281 ? | 15:12 |

| sidnei | from searching around mailing lists, there are some reports that it's fixed in 2.6.36, so maybe it merits a backport of whatever patch was applied upstream. | 15:13 |
| abogani | soren: I suppose that they prefer git format-patch'ed... | 15:25 |
| ogra | apw, how about a new meta upload for omap4 (so we actually get the new kernel onto the images) | 15:33 |
| apw | ogra, can do shortly | 15:33 |
| * ogra hugs apw | 15:33 | |
| ogra | thanks a lot ... i just wasted a day trying to find out whats wrong with the new kernel ... rsalveti just pointed out that we still use the old one | 15:34 |
| apw | doh | 15:34 |
| * ogra thinks with over 40 you need glasses :P | 15:34 | |
| * rsalveti also hugs apw | 15:36 | |
| apw | it'll take me a bit as my main dev box just wedged on X and i am trying to figure out why | 15:37 |

| apw | soren, email in a format-patch format patch to kernel-team@ | 17:11 |
| apw | sidnei, we are aware, though noone has had a chance to go look for that patch yet | 17:11 |
| apw | if you find out w | 17:11 |
| apw | which patch it is do add it to the bug | 17:12 |
| sidnei | apw, ok, i'll try to find it | 17:20 |
| sidnei | apw, added some links to patches on linus tree that seem related to the bug | 17:41 |
| sidnei | apw, hope that helps | 17:41 |
| sidnei | apw, im candidate for trying out a ppa'd package with the fixes, since i can repro on my laptop | 17:41 |
| apw | ogra, hey ti-omap4 meta ... they already seem to be in sync ? | 17:46 |
