| fabbione | i just uploaded 1.2 | 12:14 |
| fabbione | please wait to commit around that i need to do the baz dance | 12:14 |
| fabbione | and get some food before that :) | 12:14 |
| zul | hola | 01:40 |
| fabbione | hey zul | 01:41 |
| zul | hey fabbione how goes it | 01:41 |
| fabbione | the main baz repo seems to be fucked | 01:41 |
| zul | huh? | 01:41 |
| fabbione | we are investigating the problem | 01:41 |
| fabbione | there are some strange merge issues | 01:41 |
| zul | i didnt do it :) | 01:41 |
| fabbione | and i can't tag 1.2 upload | 01:41 |
| fabbione | i know :) | 01:41 |
| fabbione | it's a baz bug apparently | 01:41 |
| zul | bah...lets use cvs ;) | 01:42 |
| fabbione | i can take your word for it :) | 01:42 |

| fabbione | zul: i am almost done with the tagging :) | 02:00 |
| zul | ok im trying to track down something | 02:00 |
| fabbione | 1.3 is open :) | 02:24 |
| fabbione | have fun | 02:25 |
| fabbione | i am off for a bit | 02:25 |
| jbailey | Hmm. depmod will have to be done at boot time to deal with module assembly. =( | 02:41 |
| jbailey | I know the kernel can cause modules to be loaded automatically. Does it shell out to insmod or something, or does it rely on a hotplug event to get that right? | 02:43 |
| jbailey | I'm thinking things like sd_mod | 02:44 |
| zul | i think it relies on hotplug | 02:44 |
| zul | but im not 100% sure | 02:44 |
| jbailey | Cool. Thanks, Chuck. | 02:44 |
| zul | np | 02:46 |
| fabbione | jbailey: depmod can run at initramfs creation time, but it's always a good idea to run it at boot | 03:07 |
| fabbione | and if can.. please stop using insmod and switch to modprobe | 03:07 |
| jbailey | This is simply for the modules that exist in the initramfs for hardware autodetection. | 03:07 |
| jbailey | The problem is that at build time I can't assume that I have all the modules that will eventually be present in there, so to get the modules.aliases file right, I need to run it on the bits in the initramfs | 03:08 |
| jbailey | Already stopped using insmod in my local tree. | 03:08 |
| fabbione | jbailey: ah ok.. i see | 03:09 |
| jbailey | Booyah! She boots! | 03:32 |
| jbailey | The only modules I have to hardcode now are md, raid1, and sd_mod | 03:32 |
| fabbione | Total 2075 package(s) | 03:33 |
| fabbione | ^ sparc needs-build | 03:33 |

| jbailey | Is there any way to tell which things in kernel/drivers/net are actually for hardware devices and which ones are just things for ppp/slip etc? | 04:07 |
| fabbione | not automatically | 04:12 |
| jbailey | 'k, thanks. | 04:13 |
| fabbione | ppp is hardware.. it gives you a device back | 04:13 |
| fabbione | even if it's "virtual" | 04:13 |
| jbailey | Yeah, I was hoping for a device tag or something. | 04:13 |
| jbailey | No biggy, they're pretty small, and I can always do a blacklist later. | 04:13 |
| jbailey | Or hey, perhaps we can support NFSRoot over PPP | 04:13 |
| jbailey | *puke* | 04:13 |
| fabbione | ahahhaa | 04:14 |
| === lamont [~lamont@15.238.5.145] has joined #ubuntu-kernel | ||
| jbailey | Lesse.. Reasonable root filesystems: ext2, ext3, jfs, nfs, reiserfs, xfs. | 04:16 |
| jbailey | Would anyone try over afs, hfs or ufs? | 04:16 |
| zul | reiserfs4..hah! | 04:16 |
| jbailey | I don't see that in the Ubuntu kernel... | 04:17 |
| fabbione | ahaha | 04:18 |
| dilinger | jbailey: i'd like to get our root filesystems using afs, but i'm not sure if that's possible | 04:23 |
| dilinger | given afs has a global namespace that always has to be /afs/<cell> | 04:23 |
| dilinger | it would require some ugliness involving symlinking, for example, /usr into /afs/<cell>/root/usr or somethihng | 04:24 |
| dilinger | or bind mounting | 04:24 |
| dilinger | or something | 04:24 |
| jbailey | dilinger: Mind if I ignore that case for now? We can always add the drivers in later. | 04:25 |
| === dilinger nods | ||
| jbailey | That sounds in the same class as root over NFSv4 =) | 04:25 |
| dilinger | does nfs4 employ some weird namespace? | 04:26 |
| jbailey | It uses strong auth like Kerberos as well. =) | 04:26 |
| dilinger | interesting | 04:26 |
| jbailey | dilinger: Eh, you might know the question chuck answered earlier. | 04:27 |
| jbailey | You mentioned before that SCSI can autoload things like sd_mod when it loads the appropriate driver. | 04:27 |
| lamont | CC [M] drivers/net/fealnx.o | 04:28 |
| lamont | drivers/net/fealnx.c:907:2: warning: #warning Processor architecture undefined! | 04:28 |
| jbailey | Does it shell out to insmod, or rely on a hotplug event? | 04:28 |
| lamont | fabbione: I think we can disable that driver for hpp | 04:28 |
| lamont | a | 04:28 |
| fabbione | lamont: go ahead :) | 04:29 |
| lamont | heh | 04:29 |
| fabbione | baz commit -s'Fix FTBFS on sparc64' | 04:29 |
| === fabbione sighs | ||
| === lamont wonders if the ubuntulog bot could watch and announce baz commits to the kernel-team repository | ||
| fabbione | lamont: nope.. it knows nothing about baz | 04:31 |
| fabbione | we can make another bot for it | 04:31 |
| jbailey | Wire it up to the commits bot? | 04:31 |
| fabbione | hmmm actually.. given that sparc32 is not supported.. i could make sparc64 the default and kill sparc | 04:31 |
| lamont | kernel-team@ubuntu.com--2005/kernel-debian--pre1,2--2.6.11.94 | 04:32 |
| jbailey | It would probably be easy to write a module for CIA, and nice for baz projects to have it anyway. | 04:32 |
| lamont | that's the right version, yes? | 04:32 |
| fabbione | jbailey: no. i don't like to mix too much | 04:32 |
| fabbione | lamont: nope.. | 04:32 |
| fabbione | that's been released today | 04:32 |
| fabbione | 1,3 | 04:32 |
| lamont | you uploaded -1.2, ok | 04:32 |
| lamont | -1.2 went to main? | 04:33 |
| jbailey | fabbione: Why not? There are enough people who look at the #commits channel, and it keeps stats and such. Might just be interesting PR for Ubuntu. | 04:33 |
| lamont | s/went to/is headed for/ | 04:33 |
| dilinger | jbailey: i don't think it calls out to insmod, i think it calls the internal stuff that does module loading | 04:34 |
| fabbione | jbailey: because i don't want another extra service to run on my own server. | 04:34 |
| dilinger | jbailey: map the driver into memory, call the init function, etc. that's just a guess, though; i haven't looked at the module loading code | 04:34 |
| fabbione | jbailey: if somebody wants to set it up.. more than welcome :) | 04:34 |
| jbailey | dilinger: 'kay thanks. I'll look and see what I can find. | 04:35 |
| === jbailey adds jbd to the initramfs so that ext3 can load. | ||
| fabbione | brb | 04:37 |
| jbailey | Ugh. Now the network drivers are detected in the initramfs, which is correct, but hotplug on the boot system isn't triggered by the module loading, so the network doesn't get started. =( | 04:47 |
| lamont | jbailey: don't make us hurt you.... | 04:58 |

| Micksa | alright, hibernate works | 08:16 |
| Micksa | that was easy | 08:16 |
| Micksa | heh, even my ssh sessions stayed running 8) | 08:16 |
| jbailey | mdz: Around? | 08:36 |
| mdz | jbailey: yep | 08:43 |
| jbailey | mdz: I have all the hardware autodetection working right, but it has the side effect of not letting hotplug generate a colplug event (since the module is already loaded). The end result is that ifup is never called. | 08:44 |
| jbailey | mdz: I think the fix is in hotplug. I can upload what I have for now if you'd like to test it, though (or post .deb's or whatnot) | 08:45 |
| jbailey | mdz: s/is in/needs to go in/ | 08:45 |
| mdz | jbailey: go ahead and upload | 08:45 |
| mdz | we don't rely on a plug event to call ifup by default anyway, right? | 08:46 |
| mdz | we just do ifup -a at boot | 08:46 |
| jbailey | Hmm, it didn't on my box. | 08:47 |
| jbailey | I can look for that, though. | 08:47 |
| mdz | that's certainly how it works here | 08:53 |
| jbailey | mdz: If you're testing it locally you still might have to add ide-general or sd_mod, but all the actual hardware drivers are autodetected. The kernel is supposed to autoload those, but I'm guessing that I don't have something quite right. | 09:00 |
| mdz | jbailey: the kernel should load sd_mod when needed, but ide-generic has never worked that way (unfortunately) | 09:01 |
| mdz | jbailey: wasn't it you who implemented the workaround in the hotplug package for that? | 09:02 |
| jbailey | I did, I haven't ported that to it yet. | 09:03 |
| jbailey | dilinger said that a recent rc version included the patch to ide to make it use the driver model. | 09:03 |
| jbailey | So it might do the autoloading on its own. | 09:03 |
| jbailey | In any event, my test system for this is sata, and sd_mod isn't being autoloaded, so I'm trying to see what I need to make that happen as well. | 09:03 |
| jbailey | The rest of the hacks are nice known things, so I can just toss them in easily enough. | 09:03 |
| === jbailey gets confused. | ||
| jbailey | I didn't have auto eth0 in my interfaces file... =( | 09:07 |
| jbailey | mdz: btw, thanks for the fix to initramfs. | 09:11 |
| mdz | jbailey: no problem | 10:11 |
| mdz | jbailey: is busybox-cvs-initramfs waiting in queue/new or something? | 10:11 |
| jbailey | Filename: pool/universe/b/busybox-cvs/busybox-cvs-initramfs_20040623-1ubuntu18_powerpc.deb | 10:12 |
| mdz | ah, no, it's in universe | 10:12 |
| jbailey | I thought dependancies were automatically taken care of? | 10:12 |
| mdz | where "taken care of" means "show up in the anastacia output the next day", yes | 10:13 |
| jbailey | Ah. =) | 10:13 |
| mdz | jbailey: which MODULES choice should I used to get the network drivers included? | 10:15 |
| jbailey | It does it unconditionally at the moment. Did it miss yours? | 10:15 |
| mdz | s/used/use/ | 10:15 |
| mdz | no, I didn't look | 10:16 |
| mdz | I had MODULES=list, so I assumed it wouldn't add them | 10:16 |
| jbailey | That will be a valid assumption soon. =) | 10:16 |
| mdz | jbailey: does it get af_packet as well (for dhcp)? | 10:16 |
| jbailey | It appears not. | 10:17 |
| jbailey | (I'm in my initramfs atm) | 10:17 |
| mdz | my ethernet driver didn't get loaded | 10:18 |
| jbailey | Which driver? | 10:18 |
| mdz | oh, silly me; I installed busybox-cvs-initramfs and then forgot to go back and upgrade initramfs-tools | 10:19 |
| jbailey | =) | 10:19 |
| mdz | that's more like it; taking much longer to build the initramfs now :-) | 10:19 |
| jbailey | If you want to take a look inside it, I have a script locally that I use that basically does mkdir /tmp/initramfs; (cd /tmp/initramfs && zcat /boot/initramfs <cpio -i) | 10:20 |
| jbailey | I current save my initramfs as /boot/initramfs for testing. | 10:20 |
| mdz | jbailey: I get some error messages from invalid modprobe invocations, but it does work | 10:20 |
| jbailey | Yup, I haven't done noise reduction at all on this. | 10:21 |
| jbailey | Did you have to add af_packet? | 10:21 |
| mdz | I didn't take it out of mkinitramfs/modules | 10:21 |
| jbailey | 'k | 10:22 |
| mdz | I added it in the first place when ipconfig failed to work without it | 10:22 |
| mdz | so I assume it's still needed | 10:22 |
| jbailey | Yup, and it's definetly not getting pulled in atm. | 10:22 |
| mdz | it's probably a safe assumption that all nfs-root setups should have it | 10:22 |
| === ivoks [~ivoks@lns01-0039.dsl.iskon.hr] has joined #ubuntu-kernel | ||
| mdz | jbailey: hmm, taking nfs out of modules fails too | 10:25 |
| mdz | I end up with an initramfs which has the nfs module in it, but not its dependencies | 10:25 |
| mdz | also, the kernel-package hook doesn't seem to work | 10:25 |
| mdz | root@mizar:/usr/bin/X11 # dpkg-reconfigure linux-image-2.6.12-1-386 | 10:25 |
| mdz | Cannot find /lib/modules//lib/modules/2.6.12-1-386 | 10:25 |
| mdz | Failed to create initrd image. | 10:25 |
| mdz | looks like mkinitramfs syntax differs slightly from mkinitrd | 10:26 |
| jbailey | Hmm. I'm copying whole directory trees at this point into the initramfs. I thought I had most of what we needed for nfs. I'll add more in. | 10:26 |
| mdz | jbailey: why does it work via /etc/mkinitramfs/modules, but not via the nfs magic? | 10:29 |
| mdz | do you resolve deps in one case and not the other | 10:29 |
| mdz | ? | 10:29 |
| jbailey | Right. | 10:30 |
| jbailey | In modules, I'm actually resolving dependancies. In the other case, I'm using cp -a to get thigns from /lib/modules into the initramfs | 10:30 |
| jbailey | I can add specific things to resolve dependancies on, but I don't want to wind up with a list of drivers that we copy in - that just means we have to maintain it. | 10:31 |
| mdz | yep | 10:32 |
| mdz | jbailey: is the kernel-package thing simple to fix? it'd simplify my life | 10:33 |
| jbailey | I'm rebooting into the working system to test it now. | 10:33 |
| jbailey | I'll also add the dependancy check for nfs and af_packet | 10:33 |
| mdz | cool | 10:34 |
| jbailey | And force those to modprobe in the nfs case. | 10:34 |
| jbailey | At that point will the modules file be empty on your nfs system? | 10:34 |
| mdz | af_packet and nfs should both autoload fine, no? | 10:34 |
| jbailey | There's nothing in there to autoload them right now. If you list them in modules, they get modprobed. | 10:35 |
| jbailey | But in nfs mode, they should be modprobed too | 10:35 |
| mdz | oh, kmod doesn't work? | 10:38 |
| jbailey | Doesn't seem to, I haven't tracked that down. | 10:41 |
| jbailey | but sd_mod isn't being autoloaded either. | 10:41 |
| jbailey | I was asking dilinger about that earlier. | 10:41 |
| jbailey | mdz: Looks like 0.11 will make :33, it has your fixes. | 11:32 |
| mdz | jbailey: cool, thanks | 11:33 |
| jbailey | mdz: One of the things in the nfsroot spec currently is: Add ability to specify module loading from the kernel command line and additional module details (IRQ, IO Address, Port) to support older network cards. | 11:50 |
| jbailey | mdz the ltsp folks didn't think it was so necessary, since it's pretty rare to see non-pci devices (and our hardware detection won't find it atm anyway) | 11:50 |
| jbailey | I will hack it so that if module information is specified it will get used, but do you otherwise see any problem with dropping that? | 11:51 |
| jbailey | Either that, or I can also take a parameter for additional modules to load from the command line. | 11:51 |
