warrengeeI'm trying to figure out how to use 'make localmodconfig' with the debian/rules-style compilation. Looking at https://wiki.ubuntu.com/Kernel/BuildYourOwnKernel and https://help.ubuntu.com/community/Kernel/Compile, I'm not finding it. Any pointers?02:44

jcastroapw, hi! Did those ppc64le kernels that you wanted me to try build?10:03
arahenrix, hello!10:38
henrixara: hi10:39
arahenrix, do you know if the 12.04.5 release is going to be delayed?10:41
arahenrix, it looks like this kernel was going to be the default one: https://bugs.launchpad.net/kernel-sru-workflow/+bug/135055310:42
ubot5Launchpad bug 1350553 in Kernel SRU Workflow "linux-lts-trusty: 3.13.0-33.58~precise1 -proposed tracker" [Medium,In progress]10:42
arahenrix, but it is still waiting to be copied to -proposed10:42
araand the release was schedule to this Friday10:42
araam I missing anything?10:42
henrixara: afaik 12.04.5 is still scheduled to next Thursday10:42
henrixara: but let me have a look...10:42
arahenrix, it says Aug 7 here: https://wiki.ubuntu.com/PrecisePangolin/ReleaseSchedule10:43
henrixara: ah, i believe that is *not* the kernel that is going to be used for the release.10:44
henrixara: bjf will have to confirm this, but that kernel is already prepared for the next cycle, and will be copied into -proposed only *after* 12.04.5 is released10:44
arahenrix, ah, ok10:45
weeb1e_With software CPU control enabled in the Dell PowerEdge bios, all governers (performance or userspace + frequency) have no effect on scaling10:56
weeb1e_No matter what I do, I cannot stop the CPU on this box from scaling with Ubuntu 14.0410:56
weeb1e_I found one solution so far, but it only works for the second CPU socket11:43
weeb1e_Does anyone know how I can have "/dev/cpu_dma_latency" apply to both CPUs?11:43
fish_hi13:33
fish_I think I even asked that before already, but how do I figure out which netcfg version is used in my initrd? netcfg has no --version flag or something and initramfs-tools includes it somehow but I have no clue how and where to check for the version13:34
fish_I depend on the BOOTIF feature which was introduced in debian's netcfg 1.6313:34
fish_would be great to know which part of initramfs is actually pulling down the udeb's. greping for netcfg in the initramfs-tools script doesn't show anything13:40
hallynapw: bug 1342000 , it seems some powerpc virtio driver may have been dropped from 14.04 to 14.10 kernel?14:08
ubot5bug 1342000 in qemu (Ubuntu) "UBUNTU14.10-LE:liz:Ubuntu installation failing on virtio-scsi disk with disk image type raw" [High,Incomplete] https://launchpad.net/bugs/134200014:08
fish_ok, so BOOTIF seems to be supported, but I get "Couldn't find valid BOOTIF= entry in /proc/cmdline" although I set BOOTIF=14:52
fish_and it shows up in /proc/cmdline. I tried the mac with dashes and colons, same result14:52

fish_that's a bummer, I can't get it so parse my mac.. 15:22
fish_it looks like a bug: https://bugs.launchpad.net/maas/+bug/135030215:35

hujjjOn Ubuntu 12.04.5 there is the package linux-image-3.2.0-67-generic (http://packages.ubuntu.com/precise-updates/linux-image-3.2.0-67-generic) and the corresponding source package linux-source-3.2.0 (http://packages.ubuntu.com/precise-updates/linux-source-3.2.0), But where is the source package for linux-image-3.13.0-32-generic (http://packages.ubuntu.com/precise-updates/linux-image-3.13.0-32-generic)?17:07
hujjjThere is linux-source-3.13.0 for 14.04 (http://packages.ubuntu.com/trusty-updates/linux-source-3.13.0). But why not for 12.04 when there is linux-image-3.13.0-32-generic for 12.04?17:18
hujjjNo one here to answer my simple question?17:25
hujjjThe page http://packages.ubuntu.com/precise-updates/linux-image-3.13.0-32-generic mentions  linux-lts-trusty-source-3.13.0 with "Package not available".17:29
henrixhujjj: all the kernels source code is stored in git repositories at kernel.ubuntu.com17:30
henrixhujjj: for ex, the trusty kernels (based on 3.13) are here: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-trusty.git;a=summary17:30
=== psivaa is now known as psivaa-holiday
hujjjBut I am on 12.04.5. And there is linux-image-3.2.0-67-generic and linux-source-3.2.0. And there is linux-image-3.13.0-32-generic BUT NO corresponding linux-source package like for 3.2.0.17:32
henrixhujjj: in that case, you want to clone the ubuntu-precise repository and checkout the lts-backport-trusty branch17:33
henrixhujjj: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-precise.git;a=shortlog;h=refs/heads/lts-backport-trusty17:33
hujjjhenrix: I am doing an "git clone -b lts-backport-trusty --single-branch git://kernel.ubuntu.com/ubuntu/ubuntu-precise.git" now.17:39
henrixhujjj: yeah, something like that will allow you to have the source17:39
hujjjIs there a reason why  linux-lts-trusty-source-3.13.0 is not available as a package for 12.04.5 even linux-image-3.13.0-32-generic exists for 12.04.5?17:41
henrixhujjj: hmm... maybe because 12.04.5 hasn't been released yet?  but not sure if that's why17:41
henrixhujjj: release should happen next Thursday iirc17:41
henrix*this* Thursday actually17:42
