[03:58] [Symmetrical Multiprocessing, SMP]: Is there a tool that shows if an application program uses both processors on a particular two-processor SMP machine? [04:07] bullgard4: do you mean 'does it have threads' ? [04:10] lifeless: No. I imagine that an application may either be processed by only one processor or by both. [04:11] no, if your application has a single process it can't be using two CPUs [04:11] stgraber: it can get scheduled to both, just not concurrently :P [04:12] lifeless: right :) [04:12] bullgard4: your question is essentially ill-defined in kernel terms, heck, even application isn't that well defined (I know single apps that have 10's of different images with 100's of processes active concurrently) [04:13] bullgard4: I'm sure you are asking this as part of answering some larger issue/project - perhaps some context about that will help us answer you [04:17] May be referring to a more specific case will help me better to understand. Does pbzip2 load the two processor kernels while gzip, bzip2 do load only one? [04:19] bullgard4: pbzip2 is probably threaded, so the kernel can schedule it onto multiple CPU's at once [04:20] gzip and bzip2 are single threaded and can only be scheduled on a single cpu at a time [04:23] lifeless, stgraber: Thank you very much for your help. === smb_tp_ is now known as smb_tp [10:00] hi, why does 2.6.28-8 depend on wireless-crda which is only in universe? [10:05] remove that depend please... [10:05] is there a change hardy's latest kernel was compiled with an older version of gcc that we have in repository? [10:05] which would make building kernel modules impossible? [10:18] ivoks, Older version, no. Older revision, yes. It was built with the gcc that was available at the time it was built. [10:19] persia: i'm aware of that... [10:19] but, we can't build kernel modules if kernel doesn't get rebuild [10:20] gcc in hardy is 4.2.4 [10:20] it was updates couple of months ago [10:20] yet, the kernel is compiled with 4.2.3 [10:20] Hrm? [10:20] * persia looks [10:20] depends, you can even build the kernel with gcc 4.1.1 and then compile modules with 4.3 [10:20] just not the other way around [10:20] ivoks, Which arch? [10:20] persia: i386 [10:21] but then the linux-headers are not installable [10:26] ivoks, For some reason I can't find the build log for 23.48, apparently in part because it's a security update. Sorry not to be able to help. [10:26] persia: right, that was security update [10:29] persia: bug 292381 [10:29] Malone bug 292381 in linux "[hardy] kernel 2.6.24-21-generic and gcc version mismatch" [High,Triaged] https://launchpad.net/bugs/292381 [10:29] ivoks, It may well have been built against 4.2.3 then, as I believe -security only has 4.2.3 and -updates has 4.2.4. [10:29] ivoks, Trick being that for people only tracking -security, I think 4.2.3 is correct. [10:29] i understand that [10:29] that's a gcc bug [10:30] gcc should never get version change during release [10:30] Or at least never get any sort of ABI change. [10:30] The version string isn't the important part. [10:36] well [10:36] i just did more digging [10:37] kernel's 64bit buildd doesn't have gcc 4.2.4 [10:37] while 32bit buildd does [10:47] ivoks, Found it: http://launchpadlibrarian.net/21747228/buildlog_ubuntu-hardy-i386.linux_2.6.24-23.48_FULLYBUILT.txt.gz shows gcc-4.2_4.2.3-2ubuntu7 : it's entirely due to skew between -updates and -security. [10:48] Either needs two different kernels (one for -updates and one for -security) or to not have impactful variation. [10:48] correct [12:36] I would be interested in someone could solve this problem: [12:36] http://www.nabble.com/Yaird-throws-error-about-bad-sr0-device-link-td21449825.html [12:37] I know it's not Ubuntu-kernel related, but perhaps it's a slow morning for someone who wants to help me out [12:41] Why use yaird? What does it do that mkinitramfs doesn't? [13:00] >_> I'm using a video tutorial which stated using that tool. I'm not familiar with kernel building. [13:00] I googled the error I was getting and found that ml archive [13:05] lukehasnoname: googling I found some people having to update to a newer yaird version (with erros similar to yours), but I would do as soren suggest.. use mkinitramfs [13:19] I'll try it later. I've been awake 24 hours in studying for tests and finishing up a project proposal [13:19] thanks [13:54] hi... are there any plans to support more than 8 cpus in hardy? [13:55] ivoks: debian/config/amd64/config.server:CONFIG_NR_CPUS=64 [13:55] ah, right [13:56] so, only i386 supports 8 [13:56] correct [13:56] thanks [13:56] rtg, WIth the lpia kernel merge, does linux-lpia now have the same modules and udebs as i386/amd64 or are there significant differences? [13:57] persia: udebs should be pretty close, but I'm not sure about all of the modules. The configs came over intact, so that likely hasn't changed. [13:58] Thanks. I'm thinking some bugs I was thinking of filing may have become obsolete, but I'll retest, and maybe file. [13:59] persia: who is the archive admin today? I need to get wireless-crda promoted to main [14:00] rtg, You already have an approved MIR? [14:00] yep, hang on. [14:00] https://wiki.ubuntu.com/ArchiveAdministration#Archive%20days says nobody is the offical archive-admin on Fridays. [14:01] persia: which is why I asked [14:01] https://bugs.launchpad.net/ubuntu/+bug/325801 [14:01] Malone bug 325801 in ubuntu "Main inclusion request: wireless-crda" [Undecided,In progress] [14:01] So just beg in #u-d and any of the team might be able to help (including the few who don't have days). [14:03] Theoretically anyone in https://launchpad.net/~ubuntu-archive/+members ought to be able to do it. [14:03] persia: thanks, I'll see whom I can annoy. [14:04] actually, I thought you were on that list. [14:05] No. I signed up for enough of those "it sounded like a good idea at the time, but it's a bunch of work" things already :) [14:05] I hear yuo :) === thunderstruck is now known as gnomefreak [15:25] rtg: you forgot my patch, you only need to apply it then you get a quickcam.ko as you still have it enabled in the config [15:26] I did not forget, I just didn't do it yet. [15:26] also i had to revert one config [15:27] as you depend on something now which is only in jaunty universe [15:28] wireless-crda is not even in main... [15:28] of course i used =y [15:29] and removed that depend === Kano is now known as Kano32 === Kano32 is now known as Kano === Nicke_ is now known as Nicke === wgrant_ is now known as wgrant [23:24] hi [23:24] is any kernel dev awake around here? [23:25] if it wasn't to much trouble [23:25] could some one take a look at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/329254 [23:25] Malone bug 329254 in linux "kernel: [ 341.030356] Pid: 0, comm: swapper Tainted: P W 2.6.28-7-generic #20-Ubuntu" [Undecided,New]
