| niktaris_lap | hi, can anyone please tell me where the patches for the ubuntu kernel are located ? | 12:32 |
|---|---|---|
| crimsun | see ubuntu-dapper.git and ubuntu-2.6.git. There're broken-out patches that I know of for Dapper and Edgy. | 12:34 |
| crimsun | there're _no_ | 12:34 |
| niktaris_lap | crimsun, they are not in the kernel source .deb. are they? | 12:46 |
| mjg59 | No | 12:47 |
| niktaris_lap | mjg59, didn't think so :) | 12:47 |
| sn9 | you could also apt-get source | 12:48 |
| niktaris_lap | I am trying to figure out why a pcmcia card works with the standard ubuntu kernel but not with a vanilla kernel | 12:50 |
| sn9 | wifi? | 12:51 |
| niktaris_lap | a vodafone 3g card | 12:51 |
| niktaris_lap | the brand is option | 12:52 |
| sn9 | when it does work, what /dev node does it use? | 12:52 |
| niktaris_lap | sn9, I will have to reboot to find that out | 12:52 |
| sn9 | no need | 12:52 |
| === gnomefreak [n=gnomefre@ubuntu/member/gnomefreak] has joined #ubuntu-kernel | ||
| sn9 | you use ppp with it, right? | 12:53 |
| niktaris_lap | sn9, I don't actually _use_ it | 12:53 |
| sn9 | you don't use the card? then how did you know it worked? | 12:54 |
| niktaris_lap | because when I use the ubuntu kernel the system sees it as usb3 modem | 12:54 |
| niktaris_lap | and with vanilla not | 12:54 |
| sn9 | that also answers my question | 12:55 |
| niktaris_lap | using kppp to query the modem | 12:55 |
| niktaris_lap | using a standard vanilla kernel I only get " CardBus card inserted into slot 0" | 12:56 |
| niktaris_lap | while with the ubuntu kernel the system goes on and configures it | 12:56 |
| sn9 | and you load the same module on the vanilla kernel? | 12:56 |
| niktaris_lap | no I don't do anything at all | 12:57 |
| niktaris_lap | the ubuntu kernel does everything while vanilla does nothing | 12:57 |
| sn9 | did you even compile the module for the vanilla kernel? | 12:57 |
| niktaris_lap | /lib/modules/2.6.17.11/kernel/drivers/usb/serial/option.ko | 12:58 |
| niktaris_lap | I even used the config from the ubuntu kernel | 12:59 |
| sn9 | ok, what happens if you try to load that module manually on the vanilla kernel? | 12:59 |
| niktaris_lap | nothing | 01:01 |
| niktaris_lap | well the module loads | 01:01 |
| sn9 | nothing in dmesg? | 01:01 |
| niktaris_lap | but besides that nothing | 01:01 |
| niktaris_lap | only [17185386.460000] pccard: CardBus card inserted into slot 0 | 01:02 |
| === gnomefreak [n=gnomefre@ubuntu/member/gnomefreak] has joined #ubuntu-kernel | ||
| sn9 | ok, so it's not associating the card with the driver. do all other cardbus cards work? | 01:04 |
| niktaris_lap | it's the only one I got | 01:05 |
| sn9 | it could be pcmcia/cardbus support didn't get compiled with patches to use config files in /etc, or the driver itself may be a different version | 01:06 |
| sn9 | you should modinfo both the vanilla version of the driver and the stock version and diff the output | 01:07 |
| niktaris_lap | option driver version v0.4 | 01:07 |
| niktaris_lap | in vanilla | 01:08 |
| niktaris_lap | don't know what is in ubuntu atm | 01:08 |
| niktaris_lap | besides the giving the same config from the ubuntu kernel I can only image a patch is applied someplace | 01:09 |
| niktaris_lap | that's why I asked | 01:09 |
| sn9 | run modinfo on both files and use the diff command | 01:10 |
| === zul [n=bob@CPE0006258ec6c1-CM000a73655d0e.cpe.net.cable.rogers.com] has joined #ubuntu-kernel | ||
| sn9 | look for changes in lines with a bunch of numbers and codes | 01:10 |
| niktaris_lap | sn9, I uninstalled the ubuntu one. :( | 01:10 |
| niktaris_lap | use the diff command where? | 01:11 |
| sn9 | but you can apt-get it again, right? | 01:11 |
| sn9 | in a shell | 01:11 |
| niktaris_lap | sn9, yes. but later as I am apt-getting something else now | 01:11 |
| sn9 | if you still have it in /var/cache/apt/archive, you might not need to wait | 01:13 |
| niktaris_lap | yes. wait... | 01:13 |

| niktaris_lap | < aliias : | 01:18 |
| niktaris_lap | is ubuntu | 01:18 |
| sn9 | yes, the alias lines were what i meant | 01:20 |
| niktaris_lap | so what should I do ? | 01:20 |
| sn9 | but the one you show is for usb, and you said this was a cardbus device | 01:20 |
| niktaris_lap | the option card is recognised as a usb device | 01:21 |
| sn9 | so this is usb over cardbus... does lsusb show it with vanilla? | 01:22 |
| niktaris_lap | all 5 devices are listed as Device 001: ID 0000:0000 | 01:22 |
| niktaris_lap | wrong! wait | 01:23 |
| niktaris_lap | no right ( I had the card unplugged but the output is the same in any case) | 01:24 |
| niktaris_lap | all 5 devices are listed as Device 001: ID 0000:0000 | 01:24 |
| sn9 | and there are no other usb devices? | 01:24 |
| niktaris_lap | connected? no | 01:25 |
| sn9 | ok, it seems there are two things that are not happening | 01:25 |
| sn9 | 1) the cardbus is not being seen as usb | 01:26 |
| sn9 | 2) even if usb were seen, the option driver wouldn't recognize it | 01:26 |
| niktaris_lap | when connecting a usb stick I get Bus 001 Device 002: ID 0930:651c Toshiba Corp | 01:27 |
| niktaris_lap | on a usb port | 01:27 |
| sn9 | we have not even confirmed that #1 is supposed to happen at all | 01:27 |
| sn9 | looks like you'll have to boot the ubuntu kernel at least once more (to see whether the card is in lsusb there) | 01:28 |
| niktaris_lap | ok give me 1 min | 01:28 |

| sn9 | the option.ko is clearly not the only module involved | 01:41 |
| niktaris_lap | done | 01:41 |
| sn9 | look through dmesg for the last mentions of usb | 01:44 |

| niktaris_lap | sorry!!!! | 01:47 |
| niktaris_lap | sn9, at least you see them all :S | 01:47 |
| sn9 | does the laptop have any built-in usb1.1 ports, or are they all usb2? | 01:49 |
| niktaris_lap | all usb2 | 01:50 |
| sn9 | then the other module involved is ohci_hcd.ko | 01:51 |
| sn9 | that's in your lsmod, right? | 01:52 |
| niktaris_lap | sn9, so if I reboot and load ohci_hcd.ko, usbserial and option modules it should work ? | 02:04 |
| sn9 | before you do that, | 02:05 |
| sn9 | see which of those is not auto-loaded | 02:06 |
| sn9 | diff the modinfo's for that one | 02:06 |
| niktaris_lap | for ohci_hdc.ko ? | 02:06 |

| niktaris_lap | moprode ohci-hdc, usbserial , option | 02:14 |
| sn9 | diff the modinfo's for ohci_hcd | 02:14 |
| niktaris_lap | still nothing | 02:14 |
| sn9 | look for changes in the alias lines | 02:15 |
| niktaris_lap | alias is the same | 02:17 |
| sn9 | no change? | 02:18 |
| niktaris_lap | nope | 02:18 |
| sn9 | in other words, alias does not show up in the diff? | 02:18 |
| niktaris_lap | yes | 02:18 |
| niktaris_lap | only filename and vermagic | 02:19 |
| sn9 | if alias shows up in modinfo but not in the diff, and you modprobed it, look at dmesg | 02:19 |
| niktaris_lap | alias in modinfo shows. dmesg: [17179906.956000] pccard: CardBus card inserted into slot 0 | 02:20 |
| sn9 | no mention of ohci in dmesg? | 02:21 |
| niktaris_lap | no | 02:21 |
| sn9 | even though you modprobed ohci_hcd? | 02:21 |
| niktaris_lap | oh sorry | 02:22 |
| niktaris_lap | yes | 02:22 |
| niktaris_lap | [17179708.164000] ohci_hcd: 2005 April 22 USB 1.1 'Open' Host Controller (OHCI) Driver (PCI) | 02:22 |
| niktaris_lap | when modprobed | 02:22 |
| sn9 | but no other mentions of ohci? | 02:22 |
| niktaris_lap | nothing more | 02:22 |
| sn9 | i think you have an acpi or irq problem, then | 02:23 |
| sn9 | save the entire dmesg to a file from both kernels, diff them, and look for the first mentions of acpi, apic, or pci in the diff | 02:25 |
| niktaris_lap | sn9, diff-ing the /boot/config files of both kernel I see some diff in acpi | 02:26 |
| niktaris_lap | so there should be a apci patch be applied to the ubuntu kernel | 02:27 |
| sn9 | either that or kernel args | 02:28 |
| niktaris_lap | eg SCSI_SATA_ACPI exists in ubuntu kernel but not in vanilla | 02:28 |
| sn9 | unless you actually have sata in your laptop, that is not the cause | 02:29 |
| niktaris_lap | diff are: CONFIG_ACPI_SBS=m CONFIG_ACPI_PCC=m CONFIG_ACPI_SONY=m CONFIG_ACPI_DEV=m CONFIG_ACPI_TC1100=m CONFIG_ACPI_INITRD=y CONFIG_ACPI_DEV=m | 02:32 |
| niktaris_lap | those do not exist in vanilla | 02:32 |
| sn9 | but that's in the .config | 02:33 |
| niktaris_lap | yes but doesn't that mean that the modules do not exist ? | 02:33 |
| sn9 | are there acpi/apic/pci diffs in the dmesg? | 02:33 |
| niktaris_lap | I remember some acpi events when pluging in the card | 02:34 |
| niktaris_lap | have to reboot to see though | 02:34 |
| sn9 | yes, it means the modules do not exist, but if they were never in lsmod, what does it matter? | 02:34 |
| sn9 | i said to save the entire dmesg to a file under both kernels | 02:35 |
| niktaris_lap | ok I ll do that | 02:35 |
| sn9 | diff those, looking for the first occurrences of acpi or apic or pci in the diff | 02:36 |
| niktaris_lap | ok | 02:36 |

| niktaris_lap | after PCI: Enabling device 0000:07:00.0 (0000 -> 0002 | 02:44 |

| niktaris_lap | in vanilla | 02:46 |
| sn9 | that's the only diff before insertion? | 02:47 |
| niktaris_lap | from what I can see | 02:47 |
| niktaris_lap | let me check again | 02:47 |
| niktaris_lap | one diff is ACPI: Looking for DSDT ... not found! | 02:51 |
| sn9 | on vanilla? | 02:52 |
| niktaris_lap | on ubuntu | 02:54 |
| sn9 | and that line is just skipped on vanilla? | 02:55 |
| niktaris_lap | yes | 02:56 |
| mjg59 | That code isn't in vanilla, hence the difference | 02:57 |
| sn9 | but other than those two lines, the diffs only start after insertion, right? | 02:57 |
| niktaris_lap | after the insetion I get ACPI: PCI Interrupt 0000:07:00.0[A] -> Link [LNKC] -> GSI 11 (level, low) -> IRQ 11 | 02:59 |
| sn9 | i'll take that as a yes | 02:59 |
| niktaris_lap | there is http://gaugusch.at/acpi-dsdt-initrd-patches/acpi-dsdt-initrd-v0.8.2-2.6.17.patch | 03:01 |
| niktaris_lap | maybe this is included in ubuntu | 03:01 |
| mjg59 | It is | 03:04 |
| niktaris_lap | mjg59, thanks | 03:07 |
| niktaris_lap | let me apply this patch first and test again | 03:07 |
| niktaris_lap | thanks a million sn9 | 03:08 |
| niktaris_lap | thanks all | 03:08 |
| sn9 | niktaris_lap: why did you want a vanilla kernel, anyway? | 03:08 |
| mjg59 | That patch isn't going to change anything | 03:08 |
| niktaris_lap | mjg59, why? | 03:09 |
| mjg59 | Because it's got nothing to do with the problem you have | 03:09 |
| niktaris_lap | sn9, I like vanilla kernels | 03:09 |
| mjg59 | Only three lines of it are actually running on your machine, and the only thing they do is print the message you're seeing | 03:09 |
| mjg59 | niktaris_lap: Shame that they don't seem to work in this case... | 03:10 |
| niktaris_lap | mjg59, well something is different in ubuntu kernel . Since I use the same config I guess some patch does the diff. | 03:11 |
| niktaris_lap | at least I found one :) | 03:11 |
| mjg59 | There's several hundred patches in the Ubuntu kernel | 03:13 |
| mjg59 | One of them causes the difference. I don't know which one, but it isn't that one. | 03:13 |
| niktaris_lap | mjg59, it would be nice if they where located someplace... | 03:14 |
| sn9 | they are | 03:16 |
| sn9 | if you apt-get source, you get them all | 03:16 |
| mjg59 | They're in the git repository | 03:22 |
| mjg59 | We don't keep them as independent patches | 03:22 |
| zul | we use to but its more harder to maintain if we didnt use a git repository | 03:23 |
| niktaris_lap | have to go | 03:26 |
| niktaris_lap | thanks again. | 03:26 |

| niktaris_lap | hi, I downloaded the git tree, how do I see the ubuntu specific changes? | 05:54 |
| Keybuk | bisect it with other trees? | 05:54 |
| niktaris_lap | ubuntu vs vanilla | 05:55 |

| niktaris_lap | Keybuk, do I have to download the vanilla tree also ? | 06:15 |
| Keybuk | niktaris_lap: I'm afraid I don't know git | 06:17 |
| niktaris_lap | Keybuk, me neither :) | 06:18 |
| Keybuk | tbh, I've never understood why the kernel developers like it so much | 06:20 |
| Keybuk | to me it's always seemed complicated and obtuse | 06:20 |
| niktaris_lap | I am just trying to find the ubuntu specific changes (aka patches | 06:22 |
| niktaris_lap | I hope someone is kind enough to walk me through | 06:23 |
| Keybuk | that's difficult to judge | 07:07 |
| Keybuk | e.g. is ubuntu pulling the acpi tip an ubuntu specific change? | 07:07 |
| mjg59 | Keybuk: Because its merging stuff is magic | 07:09 |
| Mithrandir | zul: what's the state of xen now? You said some days ago you were going to package up some xen-restricted-modules? | 07:11 |
| mjg59 | Keybuk: I merged acpi tip with our own acpi crack in under an hour, despite there being 158 of them | 07:11 |
| mjg59 | Hm. That's not a good start. | 07:11 |
| mjg59 | "This computer does not have enough space for temporary files. Windows installation needs at least 306 megabytes of space on any partitoin for temporary files" | 07:12 |

| niktaris_lap | hi again, so there is no easy way of finding out what patches are applied in the ubuntu kernel ? | 09:18 |
| Mithrandir | niktaris_lap: patches compared with what? | 09:20 |
| Mithrandir | zul: do you have your xen repo online somewhere? | 09:20 |
| niktaris_lap | Mithrandir, to vanilla | 09:20 |
| niktaris_lap | Debian would work also I guess | 09:21 |
| Mithrandir | niktaris_lap: download the kernel.org tree, download our tree, run diff -Nru | 09:21 |
| Mithrandir | or look at the git commit log and diff that with Linus's git tree | 09:21 |
| mjg59 | But no, there's no trivial way to determine whether a given patch came from upstream or us | 09:21 |
| niktaris_lap | Mithrandir, I downloaded ubuntu tree. Don't know how to download the vanilla git tree. where a the git commit logs located? | 09:22 |
| Mithrandir | niktaris_lap: "git log" gives you the commit logs, iirc | 09:22 |
| Mithrandir | zul: it looks like the xen kernel could benefit from having the bd_claim patch applied. | 09:23 |
| niktaris_lap | Mithrandir, can I see the changes based on the commit number eg. commit cda2a116920d69ff82689b4f92e98e32d346c632 | 09:24 |
