BenC | infinity: blah | 02:12 |
infinity | BenC: Waking up? | 02:13 |
BenC | wow | 02:13 |
=== BenC sees build failures galore | ||
=== pitti [n=pitti@ubuntu/member/pitti] has joined #ubuntu-kernel | ||
infinity | BenC: A few linux-libc-dev related ones, which I'm trying to sort whose fault they are. | 02:14 |
pitti | hi | 02:14 |
infinity | BenC: pitti's got one for you, and then I'll take my turn. :) | 02:14 |
BenC | well all of l-s-2.6.17 failed too, so I'm checking that as well :) | 02:15 |
infinity | Yeah, but if another upload's required, we may as well wait and see if the headers need fixing first. :) | 02:15 |
infinity | BenC: Ping me when you're done pondering pitti's bug. | 02:20 |
BenC | ok, I'm working on that one now | 02:21 |
pitti | BenC: you agree that unaligned.h is legitimate for userspace? | 02:21 |
BenC | pitti: Not sure yet | 02:22 |
BenC | pitti: I'm going to have to say no | 02:23 |
fabbione | hey Ben | 02:24 |
fabbione | BenC: i assigned a few FTBFS to you since they involve mixture of kernel and userland headers (during a mass filing) | 02:24 |
fabbione | BenC: if it's a big time issue for you to work on them, i am sure pitti will love to help you :) | 02:24 |
pitti | BenC: ok; any idea how programs can do an unaligned read/write in a platform independent manner? | 02:24 |
BenC | pitti: main reason is that sparc64 uses asm-generic/unaligned.h and that can't be in userspace | 02:25 |
BenC | pitti: Are there programs other than reiserfsprogs that try to do this? | 02:25 |
pitti | BenC: not to my knowledge, but I can't really say | 02:25 |
pitti | BenC: we have to check the other FTBFSes | 02:25 |
BenC | pitti: Isn't there some gcc or glibc defined way of doing this already? | 02:26 |
=== _human_blip_ [n=mike@220.157.65.29] has joined #ubuntu-kernel | ||
BenC | I mean, if it's such a common thing, I would think that there is a more "official" method | 02:27 |
pitti | BenC: (making a clueless face) | 02:27 |
infinity | Amazingly, I can picture that face. | 02:28 |
BenC | pitti: From what I can tell, accessing unaligned data is not a problem, and get_unaligned/put_unaligned is only important for some architectures to improve performance a bit | 02:30 |
BenC | and from what I can tell, that's only the case for sparc64 for us | 02:31 |
BenC | the other arch's, the macros are pretty much (foo) and (foo = bar) | 02:31 |
pitti | BenC: it's definitively not a problem on x86/amd64, but I wasn't sure whether some arches would spill SIGBUSes for that | 02:31 |
pitti | BenC: and on sparc64? will it work, just slowly? or sigbus? | 02:32 |
infinity | I could just remove reiserfsprogs from the archive and solve the problem that way. | 02:36 |
infinity | :P | 02:36 |
=== pitti will fix it once he knows whether or not it will break sparc64 | ||
BenC | pitti: It should not...come to think of it, using asm-* in userspace is pointless for a few reasons, but mainly because it says nothing about the actual cpu you are running on | 02:39 |
BenC | ppc -> ppc64, sparc ->sparc64, i386 -> x86_64 | 02:40 |
pitti | ok | 02:40 |
pitti | BenC: ok, I'll fix that the naive way then; thank you! | 02:40 |
pitti | (bug updated and rejected for l-s-2.6.17 | 02:40 |
pitti | ) | 02:40 |
BenC | pitti: I would just copy the macros from i386 unaligned.h and plug those in instead of the asm/unaligned.h include | 02:40 |
pitti | yeah, I did something similar | 02:41 |
pitti | the code already had such a fallback for powerpc | 02:41 |
pitti | I just made that non-ppc-specific | 02:41 |
infinity | BenC: My turn? :) | 02:41 |
BenC | shoot :) | 02:41 |
infinity | http://librarian.launchpad.net/4822044/buildlog_ubuntu-edgy-i386.directfb_0.9.24-4ubuntu2_FAILEDTOBUILD.txt.gz | 02:42 |
infinity | Now, I'm not entirely sure how this could possibly build WITHOUT agpgart.h, so I'm curious if you need to mangle agpgart.h to be userspace-friendly, or if I should be pulling all the symbols from agpgart.h into directfb (ugh) | 02:42 |
=== pitti [n=pitti@ubuntu/member/pitti] has left #ubuntu-kernel ["Bye"] | ||
BenC | infinity: icky...that just looks like newer agp API | 02:48 |
infinity | BenC: Any urge to take this one off my hands and make it build on amd64/i386? I got it building on all other arches (yes, the package had at least 4 different FTBFS bugs) | 02:49 |
BenC | infinity: I can give it a go | 02:49 |
=== ph8 [i=henri@85.234.155.95] has joined #ubuntu-kernel | ||
infinity | BenC: Once I start diving into kernel/userspace separation, I get a bit hazy as to whose bug is whose (kernel, headers, app) | 02:49 |
BenC | infinity: This is basically a "directfb is too old" bug | 02:50 |
infinity | That doesn't shock. The bitrot can't be too bad, though. :/ | 02:51 |

nixternal | [17180132.352000] APIC error on CPU0: 01(01) | 06:17 |
nixternal | ever since tuesday, i switched to the -generic kernel, and now i get those | 06:18 |
nixternal | i had this with the k7 kernel previously, and when i went back to the 386 kernel, the problem went away | 06:18 |
BenC | nixternal: Try booting with noapic | 06:28 |
nixternal | it won't | 06:29 |
BenC | nixternal: Then I suggest for now sticking with the -386 kernel | 06:29 |
nixternal | hehe, i am ;) | 06:29 |
BenC | nixternal: File a bug and attach dmesg (or digital photo) of the problem boot without "quiet splash" | 06:29 |
nixternal | just wanted to know if anyone knew of this..i didn't even see a bug for it..so i am filing one...also, you research the error on google, they say defective hardware, which i doubt that is the issue | 06:30 |
BenC | a little info on your hardware too | 06:30 |
nixternal | no problem | 06:30 |
BenC | nixternal: I don't doubt that it could be buggy or defective hardware, but it could be something that can be worked around | 06:30 |
nixternal | it is top knotch stuff here ;) | 06:31 |
nixternal | however, im pointing towards memory if it is an issue though | 06:31 |
nixternal | i think i noticed it with a 1gb stick installation | 06:31 |
nixternal | first | 06:32 |
BenC | nixternal: New doesn't mean "not broken" :) | 06:40 |
BenC | nixternal: You may want to check on a BIOS update as well | 06:41 |
nixternal | hehe, believe me i know. this is a kt333 mobo, i think they stopped with bios hacks years back...need to find out if there are any custom ones out there though | 06:44 |
nixternal | BenC: the noapic option actually didn't lock the machine up like it had before. and it seems to have fixed something else i had an issue with on startx kicking in kdm in automatically, don't know if htey are tied in, but thats my story and im sticking to it | 06:53 |
nixternal | however,t he error is still there ;( | 06:54 |

tfheen | zul: is that the git://dev.laptop.org/projects/ubuntu-xen repo or some other? | 08:17 |
zul | ubuntu-xen-2.6.17 | 08:29 |
tfheen | cloning now. | 08:30 |
tfheen | any idea when we'll have working xrm? | 08:31 |
zul | when the headers are fixed again | 08:31 |
tfheen | any idea when that happens? :-P | 08:31 |
zul | this weekend probably :) | 08:31 |
