| Kamping_Kaiser | Hi, could someone explain the difference between https://launchpad.net/ubuntu/+source/linux and http://packages.ubuntu.com/search?keywords=linux-image-generic (or http://packages.ubuntu.com/search?keywords=linux ) | 10:00 |
| Kamping_Kaiser | the LP link indicates that hardy-security and hardy-updates share the same kernel versions, but p.u.c has them marked as different versions still | 10:01 |

| maxb | Kamping_Kaiser: In the LP link, you are looking at the "linux" source package. In the p.u.c link, you are looking at the "linux-meta" source package | 11:50 |
| maxb | Yes, it's a little confusing that the "linux" binary package is built by the "linux-meta" source package, not the "linux" source package | 11:51 |
| Kamping_Kaiser | maxb, ah. so on LP i need to be looking at 'linux-meta' instead? | 11:51 |
| Kamping_Kaiser | I should probably move a bug report then, since it relates to the linux-meta packages not linux. | 11:53 |
| maxb | Well, that depends which package you're actually interested in :-) | 11:53 |
| Kamping_Kaiser | linux-image-386 | 11:54 |
| Kamping_Kaiser | 350 bugs against linux-meta. criky. not sure moving the bug in there is going to help it | 13:06 |
| Kamping_Kaiser | How can I mark https://bugs.launchpad.net/bugs/342638 as affecting linux-meta not linux ? | 13:10 |

| erle- | did anyone try to build kernel 2.6.29.1 with make-kpkg? | 14:01 |
| === k-s[AWAY] is now known as k-s | ||
| asac | is there a hackish way to force a different vendor/product id for a usb device (e.g. so i can test a driver with a new device without rebuilding the kernel)? | 14:25 |
| Kamping_Kaiser | hex editor + kernel module? hackish enough? ;) | 14:27 |
| asac | hehe | 14:28 |
| asac | good idea | 14:28 |
| asac | too bad ... cant find the id ;) | 14:33 |
| asac | is there anything i can look for in the module to find the right spot? | 14:33 |
| asac | its cdc_ether ;) | 14:34 |
| erle- | are the "mainline" kernels patched? | 14:34 |
| erle- | i thougt that are vanilla kernels | 14:34 |
| asac | heh. i think i found it :) | 14:36 |
| asac | now i am scared ;) | 14:36 |
| anubhav | asac: why not just recompile the module with your vend id and prod id | 14:38 |
| asac | anubhav: hmm. whats the best way to just build a module? | 14:38 |
| anubhav | offcourse you will need sources | 14:39 |
| asac | i dont have a built tree here ;) | 14:39 |
| anubhav | you are building against the standard ubuntu kerenel? | 14:39 |
| asac | anubhav: i want to do that because i this thing also has some drivers that are not in mainline | 14:40 |
| asac | so yes | 14:40 |
| asac | i want to build a patched cdc_ether.ko | 14:40 |
| asac | against current jaunty | 14:40 |
| asac | darn ... now i cannot get the raw file from kernel.ubuntu.com ... gives me a 0 bytes download | 14:42 |
| asac | good now it worked | 14:43 |
| erle- | shouldn't a vanilla kernel build with a config of the ubuntu mainline kernel? (same kernel version!!) | 14:44 |
| asac | anubhav: so i have the patched module source ... what i can do now? | 14:45 |
| amitk | erle-: mainline kernels are stock linus' trees with the ubuntu config | 14:46 |
| erle- | amitk, i know | 14:46 |
| erle- | but it doesn't build here ... | 14:46 |
| erle- | Makefile:529: /usr/src/linux-source-2.6.29/arch/xen/Makefile: No such file or directory | 14:46 |
| erle- | make[1]: *** No rule to make target `/usr/src/linux-source-2.6.29/arch/xen/Makefile'. Stop. | 14:46 |
| erle- | make: *** [conf.vars] Error 2 | 14:46 |
| erle- | i have no idea, why | 14:46 |
| erle- | i don't care about xen | 14:46 |
| asac | amitk: do you have any clue? i need to just build a single kernel module file i have here | 14:47 |
| amitk | asac: cdc-ether is compiled in? | 14:47 |
| * amitk checking | 14:47 | |
| asac | amitk: its a module ... i need to build it with more device ids | 14:48 |
| amitk | aah | 14:48 |
| asac | amitk: http://paste.ubuntu.com/144184/ | 14:48 |
| amitk | asac: yes, it can be done AFAIK. Just looking for the right /sys file to put that info in | 14:49 |
| asac | the other idea was to use hexedit ;) | 14:49 |
| asac | my first hope was that i can force a different vendor/product id on that device somehow | 14:49 |
| asac | just to test | 14:49 |
| amitk | asac: /sys/module/cdc_ether/drivers/usb:cdc_ether/new_id | 14:50 |
| erle- | now i use the sourcecode from the mainline thing and the config from the mainline thing and it still does not build ... | 14:50 |
| asac | amitk: what can i do with that? | 14:51 |
| amitk | asac: still looking for the exact incantation | 14:51 |
| erle- | does nobody have an idea? | 14:51 |
| amitk | erle-: it doesn't always build and it is too early on a weekend for me to know why :) | 14:51 |
| erle- | it says he cannot build xen or something | 14:52 |
| erle- | but there is no xen in the source code which actually should have been built | 14:52 |
| erle- | do you use make-kpkg to build? | 14:53 |
| erle- | maybe it is the tool failing | 14:53 |
| asac | ok so its a colon separated list | 14:58 |
| asac | amitk: http://paste.ubuntu.com/144189/ | 14:58 |
| asac | thats what i found on google :) | 14:59 |
| asac | now i have to find the values for everything before vendor | 14:59 |
| erle- | it build now | 15:00 |
| erle- | but i had to mod the configuration manually ... | 15:00 |
| asac | hmm ... not sure if its the same for usb though | 15:01 |
| amitk | asac: do a 'modinfo cdc-ether' | 15:02 |
| amitk | the format of the alias strings might work | 15:02 |
| asac | looking | 15:02 |
| amitk | it is a concatenated string | 15:02 |
| amitk | v=vendor, p=productid, etc. | 15:02 |
| asac | echo 'usb:v413cp8147d*dc*dsc*dp*ic02isc0Aip00*' > /sys/module/cdc_ether/drivers/usb\:cdc_ether/new_id | 15:04 |
| asac | bash: echo: write error: Invalid argument | 15:05 |
| asac | echo "0 0 ffffffff ffffffff 413c 8147" > /sys/module/cdc_ether/drivers/usb\:cdc_ether/new_id | 15:07 |
| asac | amitk: that didnt complain | 15:07 |
| asac | ;) | 15:07 |
| amitk | asac: New PCI IDs may be added to a device driver pci_ids table at runtime | 15:08 |
| amitk | as shown below: | 15:08 |
| amitk | echo "vendor device subvendor subdevice class class_mask driver_data" > \ | 15:08 |
| amitk | /sys/bus/pci/drivers/{driver}/new_id | 15:08 |
| amitk | All fields are passed in as hexadecimal values (no leading 0x). | 15:08 |
| amitk | The vendor and device fields are mandatory, the others are optional. Users | 15:08 |
| amitk | need pass only as many optional fields as necessary: o subvendor and subdevice fields default to PCI_ANY_ID (FFFFFFFF) o class and classmask fields default to 0 o driver_data defaults to 0UL. | 15:08 |
| amitk | Note that driver_data must match the value used by any of the pci_device_id | 15:08 |
| amitk | entries defined in the driver. This makes the driver_data field mandatory | 15:08 |
| amitk | if all the pci_device_id entries have a non-zero driver_data value. | 15:08 |
| amitk | asac: so usb should be the same | 15:08 |
| asac | amitk: yeah ... but it didnt really do anything | 15:10 |
| asac | but i dont know what to expect | 15:10 |
| asac | i hoped that it showed up in hal ; | 15:10 |
| anubhavrocks | asac: but the string you echo'd is diffrent from what amitk said | 15:11 |
| asac | yaeh | 15:11 |
| anubhavrocks | you mean to say PCI and USB have diffrent conventions? | 15:12 |
| asac | echo "413c 8147" > /sys/module/cdc_ether/drivers/usb\:cdc_ether/new_id | 15:12 |
| asac | amitk: would you think that that triggers udev events automatically? | 15:13 |
| anubhavrocks | asac: i think this should work | 15:15 |
| amitk | asac: it should, if the driver can actually bind to that particular device | 15:15 |
| asac | i am quite sure it would work as its the same device just rebranded for dell | 15:16 |
| amitk | http://jk.ufisa.uninett.no/usb/ | 15:16 |
| amitk | asac: ^ | 15:16 |
| asac | hmm ... unplugging is difficult for me ;) | 15:19 |
| asac | ok trying udev rule | 15:21 |
| asac | any idea what zaurus driver does? | 15:25 |
| asac | ok rebooting | 15:27 |
| asac | no change | 15:33 |
| asac | not sure whz zaurus is always loaded | 15:34 |
| anubhavrocks | blacklist the driver if you don't want it to load | 15:35 |
| asac | i did that | 15:36 |
| anubhavrocks | your problem is that when you insert your device the zaurus module loads instead of cdc_ether? | 15:38 |
| asac | not sure. could be ... i think my problem is that just the device/vendor id is not enough | 15:39 |
| asac | wait a sec | 15:39 |
| asac | http://paste.ubuntu.com/144215/ | 15:39 |
| anubhavrocks | checkk the output of lsusb and make sure you enter the correct Vid Pid | 15:39 |
| asac | i think i also need to tell new_id that its USB_CDC_SUBCLASS_MDLM, | 15:39 |
| asac | anubhavrocks: well. those are correct ;) | 15:40 |
| asac | i get complain about invalid mdlm descriptors in dmesg | 15:40 |
| asac | so i think thats really the problem | 15:40 |
| asac | 16:08 < amitk> echo "vendor device subvendor subdevice class class_mask driver_data" > \ | 15:42 |
| asac | how could i encode a subclass there? | 15:42 |
| anubhavrocks | asac: lsusb -v | 15:45 |
| asac | so back to square oone ... how can i just build this bloody .c file ;) | 15:45 |
| asac | anubhavrocks: the ids are right :2) | 15:45 |
| asac | wait a sec | 15:45 |
| anubhavrocks | to get the subclass etc | 15:45 |
| asac | Bus 001 Device 003: ID 413c:8147 Dell Computer Corp. | 15:45 |
| asac | ah | 15:45 |
| asac | ok | 15:45 |
| asac | anubhavrocks: well. the problem is that i dont kinow how to encude subclass in the echo above ;) | 15:46 |
| asac | anubhavrocks: http://paste.ubuntu.com/144220/ | 15:47 |
| asac | isnt there a bloody gcc command to make a .ko out of .c ? | 15:49 |
| asac | ok so i guess i will go for hexedit option | 15:51 |
| asac | that worked!! | 15:53 |
| * asac dances!! | 15:54 | |
| asac | amitk: thanks :) ... hexeidt was the right thing i needed | 15:54 |
