fabbioneBenC: please pull from my archive when you have time. RedHat Cluster Suite update.01:02
fabbioneBenC: i would like to get it in for the next upload01:02
fabbionesince it has some nice bug fixes01:03
BenCsure thing01:21
BenCis it going to break ABI?01:21
fabbionei don't think so01:33
fabbioneyou forgot to add the ABI file for amd64-server01:33
fabbioneand that's the one i was building01:33
fabbioneso diff complained there were no files to diff01:33
fabbioneBenC: this kernel is rocking.. 01:56
fabbioneon all the test arches/machines i only have one regressions that i need to reverify with the latest build01:56
jbaileyBenC: You working today?02:12
fabbionejbailey: that's the kind of question that will never get a proper answer :)02:13
fabbionejbailey: considering Ben git commits all the way trough xmas and new year :)02:14
jbaileyfabbione: Right.  Sort of why I'm not asking him if he's hacking or not. =)02:14
fabbionehehehe02:14
jbaileyfabbione: Working is a someone related state, but not the same. =)02:14
fabbioneBenC: ah one important thing.. i am going to take my webcam in London, we need to get it working :))))02:14
fabbionei have the code from some external crap02:15
fabbionebut it's not exactly working.. anymore.. used to in .1202:15
fabbioneand the code is a fork of the $cantrememberwhatdriver that we do have02:15
fabbioneso perhaps we could do some magic on it02:15
jbaileyBenC: Whenever you are back, I wasn't able to find someone over the break who can talk about the asm-ppc/asm-ppc64 integration.02:19
=== zul [n=chuck@ubuntu/member/zul] has joined #ubuntu-kernel
jbaileyBenC: If you can help me find someone that would be lovely.  It's a very simple problem to fix, but will probably break all sorts of things.02:19
zulgday02:19
jbaileyfabbione: FWIW, with the -10 kernel I haven't seen a crash in a couple of days.02:19
jbaileyfabbione: But usually it crashes shortly after I say that.02:20
fabbionejbailey: ask benh? ;)02:20
jbaileyfabbione: He wasn't in #ppc64 much over the break.02:20
fabbionejbailey: #kernel02:21
=== jbailey shudders.
jbaileyI'll get beaten for talking about using those headers. =)02:21
fabbionejbailey: ask in /msg ;)02:21
zulhe'll get slaughtered then02:22
fabbionenah02:22
fabbionenot from benh02:22
jbaileyI'll /notify on him here for now02:23
zulbrb...new grub02:29
zuloops...wrong machine02:30
fabbioneBenC: i think i need a newer firmware02:34
fabbioneBenC: i do the iwconfig dance02:34
fabbioneifconfig eth1 up02:34
fabbioneand it switches again to 54M02:34
fabbionebut if i do again iwconfig rate it works just fine02:35
BenCweird02:44
BenCso it's working?02:44
BenCjbailey: ok, just let me know what you need done02:45
fabbioneBenC: more or less yes02:45
fabbioneone thing to avoid02:45
BenCfabbione: can you send me specs on the webcam?02:45
BenClsusb out and such02:46
fabbioneifdown foo if your rate is 54Mbit02:46
jbaileyBenC: asm-powerpc/signal.h relies on BITS_PER_LONG, which is only defined if __kernel__.02:46
fabbioneBenC: i can send you the code that was working on .1202:46
fabbioneBenC: and all the other infos02:46
fabbionei don't have a URL to the specs02:46
jbaileyBenC: asm-s390 just seems to pick an arbitrary value for public consumption in their signal.h02:46
BenC32 is a good value for ppc I think02:47
BenCsince if it isn't __kernel__, then it's userspace and probably 32-bit02:47
BenCfabbione: ok, just lsusb output and vendor/model if you can02:48
fabbioneBenC: yup02:48
jbaileyBenC: Debian has a true 64bit ppc64 port.02:48
jbaileySo that doesn't seem actually true. =(02:48
BenCI wonder if I get mol running on my wife's G5 if she will even notice that I installed ubuntu on it02:48
jbaileyBenC: I think it's just leaving buffer space in structs for things, though.  In which case the 64 bit one should be fine.02:49
jbaileyBenC: mol?02:49
BenCjbailey: then probably a quick macro test for __powerpc64__ since the compiler should define that02:49
BenCmac-on-linux02:49
jbaileyOh!  I didn't know that existed.02:49
BenCshit, mol is the bomb02:50
jbaileySo far the only mac thing I want is a game that I don't remember what it's called that ran on m68k., =)02:50
BenCit's not an emulator02:50
BenCit's a virtual machine (native mostly)02:50
jbaileyAh, cool.02:50
BenCruns OSX 10.4 easily02:50
BenCruns in a framebuffer window, and is almost native speed (no graphics accel, but that's ok)02:51
BenC#ifndef __KERNEL__02:51
BenC#ifdef __powerpc64__02:51
BenC#define BITS_PER_LONG 6402:52
BenC#else02:52
BenC#define BITS_PER_LONG 3202:52
BenC#endif02:52
BenC#endif02:52
BenCmake that first line "#if defined(__KERNEL__) && !defined(BITS_PER_LONG)02:52
BenCdamnit02:52
BenC#if !defined(__KERNEL__) && !defined(BITS_PER_LONG)02:52
BenCyeah, that will work02:53
BenCgcc -m32 doesn't define __powerpc64__02:54
BenCbut gcc -m64 does02:54
BenCjbailey: would you be able to add that to your build, or do I need to put it in the actual headers?02:54
jbaileyBenC: It should be in the actual headers, otherwise anything that uses signal.h will break.02:55
BenCok, adding it now for 10.1602:55
jbaileyThanks.02:55

fabbionei am digging into 2077104:42
zuli love battling with grub04:42
BenCso you think it's a binutils issue?04:42
fabbionethe only thing changed between 9.23 and 10.24 is binutils04:42
fabbionenow04:42
fabbionebinutils changes are trivial04:42
fabbioneonly packaging stuff04:42
fabbionethe second diff is the toolchain info on which binutils has been built04:42
fabbioneyou might notice clearly that there is more that did change04:43
BenCis binutils built self contained like gcc (IOW, it gets compiled twice, the second time by itself)?04:43
fabbionei have no idea04:43
fabbionethat's doko/elmo question04:43
BenCmaybe binutils compiled itself wrong the second time :)04:43
fabbioneit's a possibility that we can't exclude04:44
fabbioneubuntu4 was hppa/sparc specific change04:44
fabbioneassuming it was done correctly (and i think so04:44
BenC-5 was built with -4, and -6 with -5, so it could be that -5 was broken04:44
fabbioneubuntu3 is the first hit with some i386/x64_64 changes04:45
fabbioneit's a possibility04:45
fabbionei don't have enough experience to understand binutils04:45
fabbionebut there are no differences in the test suite04:46
fabbioneat least that i can see with diff -y 04:46
fabbionediff -u04:46
dokoBenC: no, it's the normal build, and then the multiarch build04:47
fabbioneBenC: it's the only thing i will have to check when elmo is back04:52
fabbioneget old binutils and try to rebuild the kernel04:52

=== jouni_ [n=jouni@letku30.adsl.netsonic.fi] has left #ubuntu-kernel ["Lhdss"]
fabbioneBenC: yes, but it's not very stable and upstream doesn't support it anymore04:58
fabbionethat's why we had the changes between hoary and breezy with power3/power4 into powerpc64-smp04:58
BenCthat reminds me, I want to make yaboot choose the correct kernel based on 64-bit/32-bit05:00

BenCamazing how much yaboot code is like silo05:01
