| tarsin | hello, my apologies if this isn't appropriate for this channel. i am trying to apply xenomai and adeos-ipipe patches to the ubuntu kernel. i downloaded the kernel source via: `apt-get source linux-source-2.6.22` when i go to apply the patch to the created directory it seems to fail in a couple of places. so instead i tried extracting the vanilla kernel that was provided from apt-get, then applied my patches. now i'd like to apply the ubuntu patches, | 05:00 |
|---|---|---|
| tarsin | i am curious if there is a better way to do what i want? or if there is a place i can find the collection of patches that make up linux-source-2.6.22_2.6.22-14.46.diff.gz, as it would be easier to exclude the just those patches that fail to apply | 05:02 |
| lamont | tarsin: for working with the (gutsy, 2.6.22) kernel, the ideal starting point is 'git clone git://kernel.ubuntu.com/ubuntu/ubuntu-gutsy.git' | 05:11 |
| lamont | and then apply your patch to a new branch vs upstream, and then merge the two branches | 05:11 |
| lamont | of course, that's probably not all that clear if you're not already a git user... | 05:12 |
| tarsin | no.. i'm not. it sounds like its not something i am gonig to be able to hack together tonight unless i spend the next 4 hours looking at it :) | 05:13 |
| tarsin | im familar with version control systems.. but not git | 05:13 |

| tomasko | hi | 08:51 |
| IntuitiveNipple | But quieter in here for this | 08:52 |
| IntuitiveNipple | I'm just looking at the Gutsy code now | 08:52 |
| tomasko | oh, cool. | 08:52 |
| tomasko | okay, so i cleaned my system of kvm stuff. i apt-get install kvm. it sets everything up and adds the kvm group | 08:54 |
| tomasko | now i try modprobe kvm-amd (with lsmod | grep kvm showing nothing) and get: FATAL: Error inserting kvm_amd (/lib/modules/2.6.22-14-generic/kernel/drivers/kvm/kvm-amd.ko): Operation not supported | 08:55 |
| IntuitiveNipple | then you do sudo modprobe kvm_amd ? | 08:55 |
| tomasko | now lsmod | grep kvm shows: kvm 64944 0 | 08:55 |
| tomasko | stock gutsy kernel, i didn't do anything funky with custom kernels, etc. | 08:56 |
| IntuitiveNipple | Hmmm, that looks as if kvm-amd doesn't like the CPU | 08:56 |
| tomasko | grep svm /proc/cpuinfo | wc -l shows 2 | 08:57 |
| tomasko | whatever, i uninstalled kvm. i don't want to reboot my computer for something that shouldn't need me rebooting | 09:00 |
| tomasko | IntuitiveNipple: if you do figure it out, let me know. i'm off to bed. thanks. | 09:00 |
| IntuitiveNipple | I'm checking the source now | 09:01 |
| IntuitiveNipple | Was the precise error "Operation not supported" ? | 09:02 |
| tomasko | Yes. | 09:03 |
| tomasko | gah, i won't get any sleep at this rate :P | 09:04 |
| IntuitiveNipple | hmmm, that is a generic error caused by internal issues | 09:04 |
| tomasko | meaning...? | 09:04 |
| IntuitiveNipple | It is not an error generated specifically by KVM | 09:04 |
| tomasko | yeargh | 09:06 |
| tomasko | is kvm really worth it? what will i get from that that i wouldn't get from qemu? | 09:06 |
| IntuitiveNipple | The error is something like this: ? | 09:06 |
| IntuitiveNipple | FATAL: Error inserting kvm_intel (/lib/modules/2.6.20-6-generic/kernel/drivers/kvm/kvm-intel.ko): Operation not supported | 09:06 |
| tomasko | i already pasted the exact error | 09:06 |
| IntuitiveNipple | It's fantastically faster... I use kvm all the time | 09:06 |
| tomasko | even if i'm emulating linux on linux? | 09:06 |
| tomasko | (fedora on ubuntu) | 09:07 |
| IntuitiveNipple | If you want to do that, use User Mode Linux, but yes, it is faster because KVM doesn't emulate user instructions, it runs them on the native CPU | 09:07 |
| tomasko | well, it's actually the olpc image on ubuntu | 09:08 |
| tomasko | but since i'll be actually testing it out on my c2d laptop, there's no sense in trying on this desktop very hard | 09:08 |
| IntuitiveNipple | I run with KVM, it works well | 09:09 |
| tomasko | anyway, goodnight. if i care about this more, i'll help test out in winter break. right now i've got work to do :( | 09:09 |
| IntuitiveNipple | I run XO with KVM, is what I meant to type! | 09:09 |
| IntuitiveNipple | night | 09:10 |
| tomasko | so gotta wake up early to get to it :( | 09:10 |
| tomasko | oh, cool. that's good to know, but sad to know won't work on my laptop for sure (which doesn't have intel's vt extensions for sure) | 09:10 |
| IntuitiveNipple | You can use user mode linux, that'll be fast | 09:11 |
| IntuitiveNipple | One thing I can think to check... has the /dev/kvm device been created and what are its permissions | 09:12 |
| IntuitiveNipple | I see: | 09:13 |
| IntuitiveNipple | $ ls -l /dev/kvm | 09:13 |
| IntuitiveNipple | crw-rw---- 1 root kvm 10, 232 2007-11-21 14:52 /dev/kvm | 09:13 |
| asabil | hi all | 10:33 |
| soren | Oh, BenC! Just the man I wanted to talk to. :) | 12:55 |
| soren | BenC: When do you suppose the first hardy kernels will hit the archive? | 12:55 |
| BenC | soren: Going to find out the status this morning | 12:56 |
| soren | BenC: Oh, good. | 12:56 |

| zdzichuBG | hi guys | 13:44 |
| zdzichuBG | I wonder, if Hardy kernel builds are planned soon? I'd like to have SATA link and hda-intel power management features on my laptop. | 13:45 |
| zul | zdzichuBG: soon.. | 13:47 |
| zdzichuBG | cool | 13:47 |
| doko | hmm, how do I set the device class of a PCI card? | 14:15 |
| kraut | moin | 15:18 |
| zul | is there a kernel team meeting this week? | 15:37 |
| === \sh is now known as \sh_away | ||
| zdzichuBG | http://guichaz.free.fr/misc/#iotop is pretty useful, but requires " Linux >= 2.6.20 with I/O accounting support". Could this be enabled in ubuntu? | 16:20 |

| zul | oi this is such pain.. | 20:16 |
