| BigBear | what i/o scedular does ubuntu use by defualt? | 01:49 |
|---|---|---|
| _ruben | hrm .. i want to take an existing kernel version (say: 2.6.24-16.30), and want to roll my own version of it (including 2 small patches) .. currently im rebuilding using the old make-kpkg approach, but im having difficulties mimicing the 'standard' versioning scheme | 11:51 |
| alex_joni | _ruben: grab it from git, and make a custom flavour | 11:55 |
| _ruben | hmm .. sounds like smth i could investigate indeed | 11:59 |
| alex_joni | there is a quide around wiki.ubuntu.com about building kernels from git | 12:00 |
| alex_joni | that should get you started | 12:00 |
| _ruben | havent checked wiki yet, using https://help.ubuntu.com/community/Kernel/Compile now | 12:01 |
| alex_joni | ok, that sounds good | 12:01 |
| alex_joni | you need to mess with debian/binary-custom.d/ | 12:02 |
| alex_joni | add another custom binary flavour, put you patches and config there | 12:03 |
| alex_joni | then build using: "AUTOBUILD=1 NOEXTRAS=1 fakeroot debian/rules custom-binary-FLAVOUR" | 12:03 |
| _ruben | git clone in progress | 12:08 |
| _ruben | hmm .. the git/flavour approach seems pretty straightforward .. nice job | 12:14 |
| _ruben | to get the -server config .. i'd just cat debian/config/$ARCH/config and debian/config/$ARCH/config.server to one file i guess/ | 12:19 |
| munckfish | BenC: got a sec? | 13:44 |
| BenC | munckfish: sure | 13:45 |
| munckfish | Over the weekend I sent a pull request for Linux Ports cause I've finally managed to get together a stable build for the PS3 | 13:45 |
| munckfish | I just wanted to know what the next steps are to get it into the intrepid repos | 13:46 |
| munckfish | note that I haven't been able to test build on anything but Cell | 13:46 |
| munckfish | so I don't know what the options are for the other arch's | 13:46 |
| munckfish | BenC: over | 13:46 |
| BenC | munckfish: I'll take a look after I catch up on email (been off for a week) | 13:47 |
| munckfish | BenC: sure take your time | 13:47 |
| _ruben | how can i get my kernel git tree to 'represent' 2.6.24-19.41 ? .. i just want to apply 2 small patches to a given kernel and not change anything else (code-wise) | 13:49 |
| * _ruben lacks proper git skills and background info on the kernel git tree | 13:58 | |
| munckfish | _ruben: can you not apply them to the current development version of the kernel from the ubuntu-hardy git tree? | 13:59 |
| munckfish | http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=summary | 14:00 |
| munckfish | Or do you specifically just want to add these patches for yourself and do not intent to contribute them? | 14:00 |
| _ruben | munckfish: personal (testing) use only .. im interesting in performance differences :) | 14:05 |
| munckfish | _ruben: the easiest way is to just checkout the hardy source as is and work with the current development version | 14:07 |
| munckfish | _ruben: the less easy way is to create a branch starting on 2.6.24-19.41 | 14:07 |
| _ruben | munckfish: how "less easy" would that be? :) | 14:07 |
| munckfish | it's worth you look at the docs for git branch and git checkout | 14:08 |
| _ruben | i browsed the commit log, but couldnt even pinpoint the exact commit to take as reference (19.41 is mentioned multiple times) | 14:08 |
| munckfish | you can reference the tag for that version | 14:08 |
| munckfish | see "git tag" | 14:08 |
| _ruben | ah, nice | 14:09 |
| munckfish | Stefan Bader tagged the version you want here: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=0717f584cfe10c9772b1b5daba51485c419fbe18 | 14:09 |
| munckfish | instead of specify a branch to to branch from | 14:09 |
| munckfish | give the tag name instead | 14:09 |
| munckfish | Git is a great great system - but it does take a while to get to grips with it | 14:09 |
| _ruben | seems reading up on git is smth to add on my (huge) todo list | 14:10 |
| munckfish | worth it though imo | 14:10 |
| munckfish | Yeah I'd recommend it - have you seen the Ubuntu kernel KnowledgeBase docs? | 14:10 |
| munckfish | they're on the wiki | 14:11 |
| munckfish | _ruben: you'll need to follow the instructions on the Maintenance guide to make a kernel build which ends up as a deb | 14:11 |
| munckfish | that is without building loads of stuff you don't need just to test something | 14:13 |
| _ruben | still havent checked the wiki yet .. working with https://help.ubuntu.com/community/Kernel/Compile .. will search the wiki now | 14:14 |
| _ruben | actually i had the wiki open as well .. just not a very helpfull page (for me) https://wiki.ubuntu.com/KernelGitGuide | 14:15 |
| amitk | _ruben: https://wiki.ubuntu.com/KernelMaintenance | 14:18 |
| _ruben | amitk: was just reading that one | 14:18 |
| amitk | ..if you are looking to build Ubuntu-based kernsl | 14:18 |
| _ruben | tho my current quest is more a git one than a kernel one i'd say :p | 14:18 |
| _ruben | as in: "how to gt my git tree to represent 2.6.24-19.41 instead of head" | 14:19 |
| _ruben | but kernel.org isnt liking me thusfar (for the git docs) | 14:19 |
| amitk | _ruben: any reason you do not want to clone the kernel tree from kernel.ubuntu.com? | 14:24 |
| _ruben | amitk: i am using that, mentioned kernel.org wrt documentation of git :) | 14:25 |
| _ruben | hmm .. my custom kernel build (based on uptodate git tree) has a linux-headers packages which depends on linux-headers-2.6.24-22 but that one doesnt get build | 14:36 |
| _ruben | debian/rules binary-headers seems to do that trick :) | 14:45 |
| munckfish | _ruben: unless you really need the headers you should just be able to install the linux-image-* package | 15:10 |
| _ruben | munckfish: i needed the headers to recompile a kmod .. but i succeeded at that .. and so far im not seeing any performance difference .. so this little project goes in the fridge for now :) | 15:11 |
| munckfish | ok | 15:12 |
| _ruben | thanks for the help/pointers tho | 15:13 |
