| ivoks | no, MOTU doesn't have anything to do with kernel | 09:41 |
| ivoks | you should make your patch available somewhere and make a notice on kernel-devel or here... | 09:41 |
| AnAnt | btw, it's not my patch, it already exists in 2.6.16 | 09:44 |
| ajmitch | then it'll be in 2.6.17, which will be in edgy | 09:45 |
| AnAnt | ok | 09:46 |
| AnAnt | you don't add features to dapper, right ? just security fixes | 09:46 |
| ajmitch | correct | 09:46 |
| ajmitch | security & critical bug fixes | 09:47 |
| AnAnt | can I get the 2.6.17 from dapper-backports when u guys start working on edgy ? | 09:47 |
| ajmitch | no, backporting the kernel would be quite a maintenance hassle | 09:47 |

| crimsun | ah, I didn't read that you patched it | 05:46 |
| crimsun | (this connection is completely buggered) | 05:47 |
| alex_joni | crimsun: sorry, might have not been very clear on that :) | 05:47 |
| alex_joni | I see the dafault compiler is gcc 4.0, I used to use 3.x for kernel builds.. is the 4.0 ok? | 05:48 |
| crimsun | I can't speak for RTAI, but 4.0 is fine in dapper, yes | 05:49 |
| alex_joni | ok, thanks | 05:49 |
| crimsun | or whichever parts of 4.0.3 are used | 05:49 |
| mkrufky | BenC: yt? I am reading bug # 33096 ... This is a result of your commit: 30fbd96c515f7ad612486dbd94099b0a461e406a ... Your commit message references an UbuntuBug 5773, but I am unable to locate that... Anyhow, It looks to me as if your changeset is wrong.... If you can somehow confirm bug #5773 (missing on launchpad.net) , then I would be happy to fix this in upstream | 05:51 |
| BenC | 5773 is probably a bugzilla bug | 05:52 |
| mkrufky | ah, i'll take a look | 05:52 |
| mkrufky | not on bugzilla.kernel.org | 05:52 |
| mjg59 | bugzilla.ubuntu.com | 05:53 |
| BenC | bugzilla.ubuntu.com | 05:53 |
| mkrufky | lol , silly me | 05:53 |
| alex_joni | any of you uses ccache when compiling new kernels? | 05:54 |
| mkrufky | ok, i see 5773, and this looks reasonable to me | 05:56 |
| mkrufky | one strange thing is that a message dated "2005-08-23" says "This bug has been fixed a long while ago, but for some reasons we forgot to close it." .... but the -git commit is dated "12 Dec 2005" | 05:57 |
| mkrufky | anyhow, I'll fix this in upstream for 2.6.18 , and i'll note it on the launchpad.net bug | 05:57 |
| zul | meh...stupid typos | 06:01 |
| alex_joni | any idea what : drivers/built-in.o: In function `imacfb_probe':imacfb.c:(.init.text+0xc91): undefined reference to `efi' means? | 06:07 |
| mjg59 | It means you're trying to build a kernel without efi support? | 06:07 |
| alex_joni | mjg59: there should be a CONFIG_EFI or similar? | 06:07 |
| mjg59 | Yes | 06:08 |
| zul | mmmm...champisonhip manager | 06:08 |
| alex_joni | mjg59: I started with a .config from a 2.6.12, and used make oldconfig.. is that bad? | 06:08 |

| alex_joni | anyone knows where the bootsplash is in ubuntu? | 08:34 |
| alex_joni | I built a new kernel, which boots alright, but it stay black during the bootphase | 08:34 |
| crimsun | that's usplash, which is userspace | 08:36 |
| crimsun | bootsplash isn't in the kernel at all | 08:36 |
| alex_joni | err, sorry.. that's what I meant.. is there a special .config entry I need to take care of (FB or defaultresolution or something like that?) | 08:37 |
| ajmitch | morning crimsun | 08:38 |
| crimsun | 'morning ajmitch | 08:38 |
| alex_joni | crimsun: the stock 2.6.15 works as it should, just my fresh built kernel doesn't | 08:38 |
| crimsun | alex_joni: there are a number of CONFIG_FB{,_*} enabled as 'y', yes | 08:38 |
| infinity | We build all the FB stuff modular, actually, but having it builtin would work just as well. | 08:40 |
| alex_joni | crimsun: checked them (they are similar to the ones in the stock config ) | 08:40 |
| alex_joni | most of them 'm' some 'y' | 08:40 |
| infinity | alex_joni: You need (at this point) either vga16fb or vesafb to make usplash happy. | 08:41 |
| alex_joni | I just diffed my config against the stock one, and I only added one line (related to RTAI), the rest is the same | 08:41 |
| infinity | vesafb will only work if you're booting with vga=XXX on the command line, otherwise you want vga16fb (which is what we default to) | 08:41 |
| crimsun | alex_joni: did you regenerate the initramfs? | 08:41 |
| alex_joni | crimsun: I used make-kpkg to make a new kernel deb and installed that. is that enough? | 08:42 |
| infinity | CONFIG_FB_VGA16=m | 08:42 |
| infinity | CONFIG_FB_VESA=m | 08:42 |
| ajmitch | heh, morning infinity | 08:42 |
| alex_joni | infinity: both set | 08:42 |
| crimsun | alex_joni: infinity knows this area better than I do. Did you use --initrd ? | 08:42 |
| alex_joni | yes | 08:43 |
| alex_joni | make-kpkg --initrd --revision=aj1 --stem=linux binary-arch | 08:43 |
| crimsun | I believe you need to exec update-initramfs, then | 08:43 |
| infinity | crimsun: make-kpkg SHOULD be popping the update-initramfs call in the kernel postinst. | 08:43 |
| infinity | Unless we messed that up for custom kernels, and we're only doing it on stock builds.... Which would suck. | 08:44 |
| infinity | And would warrant an upload to -updates, IMO. | 08:44 |
| alex_joni | infinity: any way to check? | 08:44 |
| crimsun | grep initramfs /var/lib/dpkg/info/linux-image-$(uname -r).postinst | 08:44 |
| infinity | grep update-initramfs /var/lib/dpkg/info/linux-image-2.6.15-23-686.postinst | 08:44 |
| infinity | (replacing with your package name) | 08:45 |
| infinity | Which, if you didn't use --stem=linux, is probably "kernel-image-$foo" | 08:45 |
| alex_joni | I did use --stem=linux | 08:45 |
| infinity | Kay, then linux-image-$foo. :) | 08:45 |
| alex_joni | it says: "my $update_initramfs = "/usr/sbin/update-initramfs";" | 08:46 |
| alex_joni | so I guess it does get called | 08:46 |
| infinity | Should do, yes. | 08:47 |

| infinity | Can you toss me your .config? | 08:49 |
| alex_joni | infinity: sure | 08:49 |
| infinity | This may be easier to debug if I just see it in action. | 08:49 |
| infinity | Or, alternately, toss me your kernel packages. | 08:49 |
| alex_joni | http://www.robcon.ro/config-2.6.15-magma | 08:49 |
| infinity | I trust that you won't trojan then in the next 5 seconds. | 08:49 |
| infinity | s/then/them/ | 08:49 |
| alex_joni | it might take me more than 5 seconds to upload them ;) hang on | 08:50 |
| infinity | Yeah, I see no obvious reason why this config should hate you. | 08:51 |
| infinity | update-initramfs -u -k 2.6.15-magma | 08:51 |
| infinity | That should regenerate the initramfs (again) | 08:51 |
| infinity | But I'm curious about why it's breaking in the first place, so a copy of your package might be nice. | 08:51 |
| alex_joni | they are on their way.. | 08:52 |

| infinity | (Why are there so many script kiddies in .ro? I've not yet figured this out) | 09:18 |
| alex_joni | neither have I.. too much spare time? | 09:18 |
| infinity | Could be. Someone needs to get them all involved in constructive hacking. | 09:19 |

| alex_joni | I tried.. but failed :) | 09:19 |

| === zul [n=chuck@ubuntu/member/zul] has joined #ubuntu-kernel | ||
| infinity | alex_joni: Okay, that was informative. Spotted the difference. | 09:41 |
| alex_joni | infinity: what is it? | 09:41 |
| infinity | From our package build scripts: | 09:41 |
| infinity | if [ -f kernel/drivers/video/vesafb.ko ] ; then | 09:41 |
| infinity | ln kernel/drivers/video/vesafb.ko initrd | 09:41 |
| infinity | fi | 09:41 |
| infinity | make-kpkg doesn't do that. | 09:42 |
| alex_joni | oh, I see | 09:42 |
| infinity | And initramfs-tools is specificall sanning the initrd directory to see if you have framebuffers there you want to include. | 09:42 |
| infinity | Err, with the mkdir even: | 09:42 |
| infinity | mkdir initrd | 09:42 |
| infinity | if [ -f kernel/drivers/video/vesafb.ko ] ; then | 09:42 |
| infinity | ln kernel/drivers/video/vesafb.ko initrd | 09:42 |
| infinity | fi | 09:42 |
| alex_joni | ok, so what do you advice? | 09:42 |
| infinity | There. So, you can just do that by hand in /lib/modules/$(uname -r) and regenerate your initramfs, and you'll be golden. | 09:43 |
| infinity | Or, stop using vga=XXX on your command line, cause vga16fb will work fine with your kernel. | 09:43 |
| alex_joni | infinity: I need to produce debs that will be distributed | 09:43 |
| infinity | We should probably fix make-kpkg to do the initrd/ thing for custom kernels, but that's not going to happen in dapper. | 09:43 |
| alex_joni | hmm, afaik this worked in breezy | 09:44 |
| infinity | Did you ever actually test with "vga=XXX" in breezy? | 09:44 |
| infinity | Without it, this would be working fine. | 09:44 |
| alex_joni | but I don't have vga=XXX.. do I? | 09:44 |
| infinity | You almost certainly do. | 09:44 |
| infinity | Otherwise, you'd not be seeing the black screen. | 09:45 |
| alex_joni | any idea where the vga=XXX could come from? | 09:45 |
| infinity | cat /proc/cmdline | 09:45 |
| infinity | Mine, for example: | 09:45 |
| infinity | root=/dev/sda3 ro quiet splash vga=0x343 | 09:46 |
| infinity | That last bit says "use vesafb, or give me a useless black screen if it's not available!" | 09:46 |
| alex_joni | root=/dev/hdb9 ro quiet splash | 09:46 |
| infinity | And it's not available, cause initramfs-tools isn't copying it into the initramfs. | 09:46 |
| infinity | Okay, that's bizarre... | 09:46 |
| alex_joni | no vga here.. :-/ | 09:46 |
| infinity | Let me reboot again, but I'm pretty sure your kernel should worh with vga16fb... | 09:47 |
| alex_joni | another topic, when I remove ACPI support (because RTAI conflicts with it), I get build errors... any ideea about something like this? | 09:47 |
| infinity | Oh, I am so awesome, it hurts. ?/ | 09:56 |
| alex_joni | infinity: don't tell me you nailed it? | 09:56 |
| infinity | alex_joni: Because initramfs-tools isn't finding any framebuffers in /initrd/, it's not loading fbcon. | 09:57 |
| infinity | No fbcon, no usplash. | 09:57 |
| infinity | And yes, this behaviour has changed since breezy, since I'm an idiot. | 09:57 |
| infinity | Sort of. | 09:57 |
| alex_joni | ok.. so basicly a make-kpkg bug? | 09:57 |
| infinity | Well, a me bug. | 09:57 |
| alex_joni | infinity: happens to all of us ;) | 09:58 |
| === alex_joni produces a reasonable number of bugs frequently.. | ||
| alex_joni | usually on this: http://www.linuxcnc.org/ | 09:59 |
| infinity | Now, the trick to fix this in your custom images is to do the following: | 10:00 |
| infinity | Take the snippet I pasted above, and stick it in a shell script called "post-install" | 10:00 |
| infinity | And then cp post-install your-linux-source-tree/debian/post-install before you do the make-kpkg thing. | 10:01 |
| alex_joni | oh, ok | 10:01 |
| alex_joni | trying now | 10:01 |
| infinity | Give or take. | 10:01 |
| infinity | This is untested. :) | 10:01 |
| infinity | You probably want this before it: | 10:02 |
| infinity | cd "$IMAGE_TOP/lib/modules/$version" | 10:02 |
| alex_joni | do I make it a proper shell script? #!/bin/sh on top? | 10:03 |
| infinity | If "dpkg-deb -c blah.deb" shows a /lib/modules/`$uname -r`/initrd directory with vesafb.ko in it when you're done, you win. | 10:03 |
| infinity | alex_joni: Yes, a proper shell script. | 10:04 |
| infinity | Exectuable, too. :) | 10:04 |
| alex_joni | done | 10:04 |
| alex_joni | now if I could only make it build :( | 10:04 |
| infinity | It gets called by make-kpkg after installing all the junk in the image directory, but before generating the .deb | 10:04 |
| infinity | Our Ubuntu post-install is a bit more involved, but that's one of the things it does. | 10:04 |
| alex_joni | ok, thanks for the fix | 10:04 |
| alex_joni | any idea about how to make it compile with ACPI unset? | 10:05 |
| infinity | That, I have no idea about. | 10:06 |
| infinity | Or, rather, I can't beging to have a clue given your "I get build errors" synopsis above. | 10:06 |
| alex_joni | I can post a better error message | 10:06 |
| alex_joni | arch/i386/kernel/built-in.o: In function `setup_arch': undefined reference to `check_acpi_pci' | 10:07 |
| alex_joni | drivers/built-in.o: In function `imacfb_probe':imacfb.c:(.init.text+0x1039): undefined reference to `efi' | 10:07 |
| infinity | That first one definitely shouldn't be happening... | 10:08 |
| alex_joni | I see it still is included by a #define CONFIG_X86_IO_APIC | 10:09 |
| infinity | #ifdef CONFIG_X86_IO_APIC | 10:09 |
| infinity | check_acpi_pci(); /* Checks more than just ACPI actually */ | 10:10 |
| infinity | #endif | 10:10 |
| infinity | Yeah. | 10:10 |
| alex_joni | there's a comment there "Checks more than just ACPI actually" | 10:10 |
| infinity | You beat me there. | 10:10 |
| alex_joni | right.. that one | 10:10 |
| alex_joni | I tried unsetting the X86_IO_APIC, but make oldconfig probably put it back | 10:10 |
| infinity | I'm assuming that should be #if defined(CONFIG_X86_IO_APIC) && defined(CONFIG_ACPI) | 10:11 |
| infinity | Or the former should depend on the latter. | 10:11 |
| alex_joni | I can change that (for a quick fix now) | 10:11 |
| alex_joni | any idea about the efi? | 10:11 |
| === mkrufky is now known as mkrufky-gone | ||
| infinity | Haven't played with EFI on x86 at all yet. Someone needs to send me a MacTel to play with. | 10:11 |
| alex_joni | what's efi actually? | 10:12 |
| infinity | Early load firmware for ia64 (and now MacTel) machines. | 10:12 |
| alex_joni | ok, the acpi stuff now doesn't complain anymore.. | 10:13 |
| infinity | Comparable to, say, OpenFirmware on PowerPC, OBP on Sparc, SRM on Alpha, or the godforsaken PC BIOS on traditional x86 kit. | 10:14 |
| alex_joni | oh. ok :) | 10:14 |
| infinity | (Not really comparable to the PC BIOS at all, but for the purpose of booting, serves the same needs) | 10:14 |
| alex_joni | I see the error comes from drivers/video/imacfb | 10:14 |
| alex_joni | I'll unset CONFIG_FB_IMAC | 10:15 |
| alex_joni | seems to have done the trick.. | 10:16 |
| alex_joni | brb, getting some dinner while it compiles | 10:16 |
| alex_joni | thanks again for all your help & insight | 10:16 |
