| btQuark | hello everyone | 08:46 |
| btQuark | i've just tried this one successfully - after quite some time http://www.jan-steinhoff.de/linux/synaptics-usb.html what about bringing that into the kernel -the author obviously at it | 08:49 |
| Ng | how would I want to go about interpreting the battery consumption part of the checkbox suspend tests? I suppose I should really only use it to compare against results from different kernels on the same machine? | 09:35 |
| apw | Ng, yeah its a very subjective measure | 10:00 |
| apw | my feeling is it should be considered only as an indication of maximum suspend time, and if its less than a day or two its fail | 10:01 |
| apw | before some fixes i had a like 8 hour suspend time, which was definatly wrong | 10:01 |
| Ng | bah, that means I need to put jaunty back on the machine to get a baseline to support my gut feeling that suspend time has nosedived ;( | 10:03 |
| Ng | I also need to file a bug somewhere, some of the automated resumes didn't... resume. The LEDs changed, but I had to poke the power button | 10:03 |
| * popey filed bug 387272 but isn't sure it's a kernel bug or a desktop bug, feedback welcome | 13:14 | |
| ubot3 | Malone bug 387272 in linux "[karmic] long boot time on eee 900" [Undecided,New] https://launchpad.net/bugs/387272 | 13:14 |
| rtg | cjwatson: do you have a cross compile environment for karmic ARM? Your patch series for udeb firmware isn't quite right for ARM (and probably other CPU arches without firmware) | 13:22 |
| cjwatson | rtg: nope | 13:22 |
| cjwatson | rtg: what's wrong with it? | 13:22 |
| rtg | cjwatson: it tries to copy a firmware directory that doesn't exist. I'll see if I can fix it later today | 13:23 |
| cjwatson | is it a bug in linux/debian/rules* or in kernel-wedge/commands/copy-firmware? | 13:23 |
| cjwatson | cp debian/d-i/firmware/* $(builddir)/firmware/$(arch)/ | 13:24 |
| rtg | cjwatson: linux/debian/rules | 13:24 |
| cjwatson | oh, is it that? | 13:24 |
| rtg | cjwatson: I think so, it was last Friday that I was messing with it | 13:24 |
| cjwatson | no, that can't be right, that directory does exist | 13:24 |
| cjwatson | if you can show me the error message I'll be happy to fix it | 13:24 |
| rtg | cjwatson: I'll get to it later today. | 13:25 |
| cjwatson | ok | 13:25 |
| apw | cjwatson, could there be no files in there though? | 15:27 |
| apw | then it could try and copy a file called '*' | 15:27 |
| apw | maybe some incantation of cp -r debian/b-i/firmware/ is more appropriate | 15:28 |
| rtg | apw: thats exactly what is happening. I can repro the problem quite easily, so I ought to be able to fix it justr as soon as I clear up soem other issues. | 15:28 |
| apw | rtg ack | 15:30 |
| cjwatson | rtg: did you apply all my patches? one of them creates a file in that very directory | 15:43 |
| cjwatson | so I don't see how it would be possible for that to be empty | 15:43 |
| cjwatson | it's not dynamic or anything, it's just a source directory | 15:43 |
| cjwatson | i.e. in my branch, there exists a file debian/d-i/firmware/nic-modules | 15:44 |
| rtg | cjwatson: yes, I applied all of the patches. However, I prefer patches that are bisectable so I may collapse the last 2 (once I figure out why they don't work for ARM) | 15:45 |
| cjwatson | fine by me, perhaps I should have committed them in the opposite order | 15:51 |
| apw | Keybuk, hey ... did you get to any testing on union mounty stuff | 16:02 |
| Kano | hi apw ,do you want to add headers to make external dvb modules compile | 16:09 |
| apw | which ones are missing | 16:09 |
| Kano | cp -a drivers/ieee1394/*.h $(indep_hdrdir)/drivers/ieee1394 | 16:10 |
| Kano | and for fglrx it would not hurt to add | 16:11 |
| Kano | cp -a drivers/acpi/acpica/*.h $(indep_hdrdir)/drivers/acpi/acpica | 16:11 |
| Keybuk | apw: not yet, was off on Friday | 16:12 |
| apw | Keybuk, heh no worrie | 16:12 |
| Kano | apw: firedtv will not compile without | 16:12 |
| Kano | i have got a test script for dkms | 16:13 |
| Kano | http://kanotix.com/files/fix/dkms/dvb-s2api-liplianin-dkms.sh | 16:13 |
| Kano | that compiles all dvb drivers + some additional dvb-s2 drivers | 16:13 |
| Kano | the same script can be used to update gspca drivers too, just a small change | 16:14 |
| apw | Kano, that first one seems like a reasonable request, so get that into a bug... will think about the other | 16:17 |
| apw | let me know the number so | 16:17 |
| Kano | for the other you need an extra export too | 16:17 |
| Kano | http://kanotix.com/files/kernel/unused-patches/2.6.30-export-flush_tlb_page.patch | 16:17 |
| Kano | with both things my fglrx script works with 2.6.30 | 16:18 |
| Kano | with a relatively small patch | 16:18 |
| Kano | when you dont copy the headers the patch has to contain em, thats not really useful | 16:18 |
| Kano | btw. i have have got a verified patch for avm draft-n usb sticks, will be most likely in 2.6.31 too | 16:23 |
| Kano | http://kanotix.com/files/kernel/unused-patches/2.6.30-ar9170-support-1-stage-firmare+avm-fritz.patch | 16:27 |
| Kano | you only need the firmware | 16:27 |
| === cjwatson_ is now known as cjwatson | ||
| Kano | apw: why dont you set CONFIG_HAVE_KERNEL_LZMA=y | 19:02 |
| Kano | that compresses the vmlinuz with lzma | 19:03 |
| apw | you mean CONFIG_KERNEL_LZMA ... and that is not guarenteed to be a good thing | 19:05 |
| apw | the kernel is smaller, but slower to extract from the compressed form | 19:05 |
| Kano | it is 100% a good thing | 19:05 |
| apw | there is a trade off there dependant on disk and cpu performance characteristics | 19:05 |
| Kano | decompress is always fast | 19:05 |
| apw | its 2x the CPU time to decompress over the default compression | 19:05 |
| apw | as reported by a number of sources | 19:06 |
| Kano | which means in seconds | 19:06 |
| Kano | .5s longer or what | 19:06 |
| apw | which mean double the decompress time | 19:06 |
| apw | which with a boot budget of 10s could make a difference | 19:06 |
| apw | t | 19:06 |
| apw | the point is that its not a slam dunk to change, as its a trade offf which needs measuring | 19:07 |
| Kano | the load time to load the kernel is shorter | 19:07 |
| Kano | so you win | 19:07 |
| mjg59 | I'd be amazed if the difference in size makes up for the difference in compression | 19:07 |
| apw | the laod time is shorter yes, but on a netbook where the cpu is poor and the disk is ssd | 19:08 |
| Kano | for live images you gain 5 mb when you compress kernel+initrd with lzma | 19:08 |
| apw | is it going to be faster | 19:08 |
| apw | most of that presumably comes from compressing the initrd with it | 19:08 |
| Kano | i dont have got a netbook | 19:08 |
| apw | Kano, and how does that affect my decision? | 19:08 |
| Kano | apw: well when you dont change it, i change it | 19:08 |
| apw | then you are happy, and i am happy. win | 19:09 |
| Kano | it is just a patch i want to get rid of | 19:09 |
| cjwatson | Kano: FWIW our live images only contain the kernel and initrd once, not twice as I saw you saying the other day | 19:10 |
| apw | cjwatson, it does beg the question if we could use lzma for the initrd on the CD images as they are one time build compress time wise | 19:10 |
| Kano | cjwatson: you forget the compressed filesystem! | 19:10 |
| apw | if the kernel understands both of course | 19:10 |
| cjwatson | if it works, I expect we could; speed is not so critical there | 19:11 |
| cjwatson | Kano: no, I don't. | 19:11 |
| Kano | the only way to get rid of storing it twice would be using for example grub2 as bootloader with a squashfs support module that would fetch the file from the squashfs | 19:12 |
| cjwatson | Kano: false | 19:12 |
| cjwatson | Kano: by demonstration, in the last several releases of Ubuntu :-) | 19:12 |
| Kano | you have got no /boot/vmlinuz-... in squashfs? | 19:13 |
| cjwatson | Kano: that's correct | 19:13 |
| cjwatson | Kano: the installer knows to copy it from the ISO9660 filesystem rather than from the squashfs | 19:13 |
| Kano | then you are forced to boot with iso-scan to isntall | 19:15 |
| cjwatson | no you aren't, we use ubiquity | 19:15 |
| Kano | well when you boot from network | 19:15 |
| cjwatson | you can do that with casper/ubiquity too | 19:16 |
| cjwatson | (might need some fixes since it's not tried very much, but it's basically possible) | 19:16 |
| cjwatson | and I don't see why iso-scan is a problem - you ought to have /cdrom set up properly during installation from local media anyway, several bits of code assume that and may operate a bit weirdly if it isn't there | 19:16 |
| Kano | what does happen when you used live-media-path override | 19:17 |
| Kano | does your installer support it | 19:17 |
| cjwatson | casper does but if you use that ubiquity will probably fail to understand what's going on. I invite anyone who has a problem with this to submit patches :-) shouldn't be hard to fix | 19:18 |
| cjwatson | it'd just need to read casper.conf | 19:18 |
| cjwatson | (casper does> as of karmic anywya) | 19:18 |
| cjwatson | anyway | 19:18 |
| === bjf_ is now known as bjf_afk | ||
| cjwatson | Kano: ... indeed, that's simple enough to do that I've just committed support for it | 19:43 |
| Kano | do you really need the preseed option in order that your installer works correctly | 19:44 |
| cjwatson | huh? | 19:45 |
| cjwatson | what preseed option? | 19:45 |
| Kano | file=/cdrom/preseed/kubuntu.seed for example | 19:47 |
| cjwatson | it has sensible defaults for Ubuntu | 19:47 |
| cjwatson | the preseed options arrange for the right packages to be installed appropriate to the flavour you're installing, so that we don't have to ship a separate installer for every flavour | 19:48 |
| cjwatson | (we actually do ship a preseed file for Ubuntu too; the main relevant thing it does is to arrange to install the desktop automatically. if you don't use that preseed file then (a) you'll get asked the question on alternate/server CDs (b) it makes no difference on desktop CDs) | 19:49 |
| Kano | so bascially it is useless on the desktop ones? | 19:50 |
| Kano | when this is the case, why are those files on it then | 19:54 |
| cjwatson | Kano: I didn't say that, I said that the bit that arranges to install the desktop automatically makes no difference on desktop CDs | 20:01 |
| cjwatson | Kano: though right now it's true that none of the rest of the preseed file is relevant to desktop CDs, only DVDs; but who cares? it's easier to just tell the image building infrastructure to always include it | 20:02 |
| cjwatson | premature optimisation => silly | 20:02 |
| Kano | well it is at least good to know | 20:03 |
| Kano | if i want to test u live i use currently something like | 20:03 |
| Kano | http://kanotix.com/files/fix/grub2/config/70_ubuntu_iso | 20:03 |
| Kano | did you ever see such a code | 20:04 |
| Keybuk | -9 is not a happy kernel for me | 20:48 |
| Kano | Keybuk: do you use a dvb-c card | 20:51 |
| Keybuk | no | 20:54 |
| Kano | whats your problem with it | 20:56 |
| Keybuk | hard locks after the screen is switched off | 20:57 |
| Kano | intel gfx? | 21:03 |
| Keybuk | yes | 21:14 |
| awe | sconklin: you have time for a build question? | 21:52 |
| Mike-DC | Hi everyone. I'm having trouble recompiling the stock 2.6.28-11-generic kernel in 9.04. Everything compiles fine except for the Ubuntu supplied third-party drivers. I'm rebuilding from the tar.bz2 I retrieved through aptitude. Anyone run into this before and/or have any knowledge in this area? | 23:08 |
