[05:00] <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, 
[05:02] <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
[05:11] <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
[05:12] <lamont> of course, that's probably not all that clear if you're not already a git user...
[05:13] <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
[08:51] <tomasko> hi
[08:52] <IntuitiveNipple> But quieter in here for this
[08:52] <IntuitiveNipple> I'm just looking at the Gutsy code now
[08:52] <tomasko> oh, cool.
[08:54] <tomasko> okay, so i cleaned my system of kvm stuff. i apt-get install kvm. it sets everything up and adds the kvm group
[08:55] <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
[08:56] <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
[08:57] <tomasko> grep svm /proc/cpuinfo | wc -l shows 2
[09:00] <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.
[09:01] <IntuitiveNipple> I'm checking the source now
[09:02] <IntuitiveNipple> Was the precise error "Operation not supported" ?
[09:03] <tomasko> Yes.
[09:04] <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
[09:06] <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?
[09:07] <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
[09:08] <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
[09:09] <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!
[09:10] <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)
[09:11] <IntuitiveNipple> You can use user mode linux, that'll be fast
[09:12] <IntuitiveNipple> One thing I can think to check... has the /dev/kvm device been created and what are its permissions
[09:13] <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
[10:33] <asabil> hi all
[12:55] <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?
[12:56] <BenC> soren: Going to find out the status this morning
[12:56] <soren> BenC: Oh, good.
[13:44] <zdzichuBG> hi guys
[13:45] <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.
[13:47] <zul> zdzichuBG: soon..
[13:47] <zdzichuBG> cool
[14:15] <doko> hmm, how do I set the device class of a PCI card?
[15:18] <kraut> moin
[15:37] <zul> is there a kernel team meeting this week?
[16:20] <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?
[20:16] <zul> oi this is such pain..
