[00:49] hello [00:49] i am trying to build a kernel from git [00:50] (on armhf) [00:50] and getting bales of /root/linux-linaro-tracking/net/sunrpc/auth_gss/svcauth_gss.c:1328: undefined reference to `__stack_chk_guard' type errors [00:50] do i need to do something to disable stack protection in gcc? [00:54] http://osdir.com/ml/linux-kernel/2009-02/msg04270.html [00:54] stack protection is in the kernel itself it seems [00:54] I'm sure I'm reading that naively :) === Trevinho_ is now known as Trevinho [08:00] may i ask you a somewhat intimate question? [08:01] does really anybody here use unity? [08:10] yes [08:10] i do. [08:10] but why come to the kernel channel for trolling about unity? [08:11] o noes you did it now [08:27] ohsix: he left though? ;p === fmasi_afk is now known as fmasi === fmasi is now known as Guest17509 [09:13] I want to run Ubuntu Desktop on the device which is having Android ...Please help me [09:16] abhishek, perhaps try #ubuntu-desktop with that question [09:17] cking: ok .... [09:17] cking: Can you please give me some guildlines anyways [09:17] You're immediate problems are going to be: lack of OpenGL drivers and lack of X drivers. === Guest17509 is now known as fmasi_wfh === fmasi_wfh is now known as fmasi [12:34] hi there .... I think I found a bug in the kubuntu / ubuntu kernel but I need to have a chat to confirm before logging. [12:34] anyway, there seems to be some problem with setting the frequency of some Core 2 Xtreme CPUs .... [12:34] so I recompiled the kernel without intel_pstate support and everything else as module using the classic debian system [12:34] and modprobing each module one by one and then debugging .... it turns out that p4_clockmod is loading, but return wrong frequency reading (as it should) and recommends acpi-cpufreq [12:35] but acpi-cpufreq does not actaully load, because one of the checks says that the CPU is not supported (which is incorrect). I think the bug may be in the acpi-cpufreq module. [12:35] what do you think? === fmasi is now known as fmasi_afk === fmasi_afk is now known as fmasi === fmasi is now known as fmasi_afk === fmasi_afk is now known as fmasi === fmasi is now known as fmasi_afk === fmasi_afk is now known as fmasi [15:41] lifeless: yes, that much makes sense, doesn't help me know how to make the error go away though :) [15:41] infinity: are you here/awake? === Laney is now known as KruSha666 [15:51] mwhudson: I'm one of those things. [15:52] infinity: is there some trick to building kernels from git on armhf to avoid linker errors about stack protection? [15:53] i noticed some mention of gcc 4.7 somewhere so i'm trying that now... [15:53] apw, pushed trusty master-next with all of the packaging done. no tag yet. [15:54] mwhudson: -UFORTIFY_SOURCE, I'd assume. [15:54] mwhudson: But I would have thought the kernel makefiles did that by default. [15:55] hmm [15:55] there is some of that, but only in a few places [15:55] and only for user space stuff [15:56] rtg, great [15:57] (i'm building 3.11 + sprinkles, fwiw) [16:00] infinity: build with gcc 4.7 completed === KruSha666 is now known as Laney [16:02] mwhudson, mostly we use older gccs for the arm kernels indeed [16:03] ppisati, have you built and booted trusty on armhf with gcc-4.8 ? so far the compiler has been pinned to gcc-4.7. [16:04] apw: now i know why :) [16:07] rtg: let me check the gcc version [16:08] ppisati, I know we're building with -4.7 right now, but I'm thinking about building with the default version [16:09] debian.master/rules.d/armhf.mk:gcc = gcc-4.7 [16:10] rtg: when i do some quick test using linus tree, im compiling with 4.8 [16:10] ppisati, ok, I'll assume for now that -4.8 can generate a bootable kernel [16:26] ppisati, were you going to rebase omap4 kernels for this sru cycle? [16:28] bjf: ouch, i'll do [16:38] Hello. [16:39] I've reported a while ago that I was having problems after having upgraded to kernel 3.2.0-53 on Ubuntu 12.04 amd64. [16:39] The machine wasn't booting properly into the OS, it was just showing a blinking cursor. This is still an issue. [16:41] backjlack, what was the bug number [16:42] apw: I haven't opened any bug because it's not clear whether it's a bug or just some kind of OS issue triggered by the update to 3.2.0-53+. [16:44] I'll just try 3.5 to see if that fixes it. [16:45] jsalisbury, re: bug #1245938 - please have that guy try the stable mainline kernel(s). his NIC really ought to be functional. [16:45] Launchpad bug 1245938 in linux (Ubuntu) "Intel x520 NIC's (ixgbe) stop working in 12.10, 13.04, 13.10" [Undecided,Confirmed] https://launchpad.net/bugs/1245938 === chuck_ is now known as zul === Sargun_ is now known as Sargun [17:54] rtg, ack [18:29] jsalisbury, new observation: when i suspend with "sudo pm-suspend", no freeze [18:29] maybe it is not the kernel [18:29] maybe something with X [18:29] with screen locking and so on [18:29] jsalisbury, after more tests i will report to launchpad [18:31] erle-, thanks for the info [18:46] jibel, we just dumped a new trusty kernel into the ckt PPA, will that auto fire new dkms tests ? === JanC_ is now known as JanC [20:39] apw, looks like iwlwifi power save is off by default. drivers/net/wireless/iwlwifi/iwl-drv.c:MODULE_PARM_DESC(power_save, [21:33] rtg, ta [21:38] * mwhudson is now confused that perf ever worked on arm32 [22:04] jsalisbury, rebooting gomeisa for kernel update [22:04] mwhudson, i od't think it was even built for the longest time, and done wrong often [22:05] apw: it worked for a while for me in raring [22:05] but doesn't for me now [22:05] and i even sort of know why [22:13] care to share === fmasi is now known as fmasi_afk [22:34] jjohansen, AceLan: rebooting tangerine for kernel update [22:45] apw: the MMAP events that perf synthesizes at start up put the last module processed as taking up from its start in /proc/modules up until the end of the address space [22:45] apw: and despite this being something the user space tool does, it seems that it's actually a question of which kernel is running [22:58] oh oh [22:58] is this because /proc/kallsyms now starts with a symbol with an address of 0?
