| orated | Hello! Is there a documentation on how and what all devices are mapped in /sys and/or /proc? I'm not able to find details on the same in FHS doc. | 09:48 |
| cwillu_at_work | orated, /sys is a kernel interface; fhs has nothing to say about it | 10:26 |
| cwillu_at_work | Documentation/sysfs-rules.txt and Documentation/filesystems/sysfs*.txt in the kernel tree documents it | 10:28 |
| cwillu_at_work | pay particular attention to sysfs-rules.txt if you're making something that uses it | 10:29 |
| cking | orated, http://www.kernel.org/doc/Documentation/filesystems/proc.txt | 10:31 |
| orated | Yes, thanks. I remember accessing those documentation for GPIO - http://www.kernel.org/doc/Documentation/gpio.txt (and http://squidge.sourceforge.net/gpio/README.txt) On the same line, is there any command which gives the table for GPIO pins as shown in the second link or is it from datasheets? | 10:32 |
| orated | cwillu_at_work: cking: On the same line, is there any command which gives the table for GPIO pins as shown http://squidge.sourceforge.net/gpio/README.txt or is it from datasheets? | 10:52 |
| cking | orated, that I don't know | 10:53 |
| cwillu_at_work | general-purpose-io pins are commonly defined by the specifics of the (hardware) installation | 10:53 |
| orated | cwillu_at_work: Yes, but is the last table shown in the link possible within linux? I just thought if its from data sheets or accessible from kernel | 10:55 |
| orated | Ah-ok! | 10:55 |

| dobey | hi all. is there a 3.6-rc kernel packaged up anywhere that would be installable on precise? | 14:02 |
| amitk | dobey: deb http://ppa.launchpad.net/ubuntu-x-swat/q-lts-backport/ubuntu precise main | 14:04 |
| amitk | dobey: ^^^ contains kernel and Xorg from Q (which will be supported going forward) | 14:04 |
| amitk | dobey: or you could add just the kernel team PPA for a kernel | 14:05 |
| amitk | don't have a link handy | 14:05 |
| dobey | amitk: that is only 3.5.0 though it seems | 14:05 |
| dobey | does it have Intel video code backported from the mainline 3.6 branch? | 14:06 |
| amitk | dobey: aah, you're right. I somehow read "Q kernel on P" into your question. The kernel team PPA has a mainline 3.6-rc | 14:06 |
| rtg | dobey, http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-rc5-quantal/ | 14:07 |
| amitk | http://kernel.ubuntu.com/~kernel-ppa/mainline/ | 14:07 |
| amitk | aah, rtg got there first | 14:07 |
| dobey | rtg: oooh, great, thanks. is that installable on precise? | 14:07 |
| rtg | dobey, yep | 14:08 |
| dobey | awesome. i will try that. thanks | 14:08 |

| smoser | why do our kernels print cmdline twice ? | 16:47 |
| smoser | http://paste.ubuntu.com/1199019/ | 16:48 |
| rtg | smoser, I'd think that is how grub is doing it. Look at your local dmesg. the command line doesn't appear to be duplicated there. | 16:51 |
| smoser | its not grub | 16:51 |
| smoser | that was loaded with pxe | 16:52 |
| smoser | but you might be right. | 16:52 |
| smoser | i can't refute it. | 16:52 |
| ogra_ | i have that here too ... | 16:52 |
| ogra_ | no PXE involved | 16:52 |
| ogra_ | bith have different prefixes though | 16:52 |

| rtg | smoser, I only see one thing duplicated: 'initrd=amd64/generic/precise/commissioning/initrd.gz' | 16:55 |
| rtg | oh, printed again later down. never mind. | 16:56 |
| smoser | i meant printed twice | 16:56 |
| smoser | right. | 16:56 |
| ogra_ | on omap4 kernels i inly see "Kernel command line" | 16:56 |
| ogra_ | *only | 16:56 |
| rtg | huh, on X86_64 I only see it printed once. | 16:57 |
| ogra_ | on precise x86_64 its twice | 16:57 |

| ogra_ | havent rebooted, .31 is installed already though | 16:58 |
| rtg | ogra_, ok, I wasn't searching for the right string. | 16:58 |
| rtg | smoser, is this causing you issues, or are you just curious why its printed twice ? | 17:00 |
| === orated_ is now known as orated | ||
| smoser | rtg, not causing me issue. just wondering. | 17:01 |
| smoser | and came across it when i was looking at an arm log | 17:01 |
| smoser | and i think it only had one of these. | 17:02 |
| ogra_ | yeah | 17:02 |
| ogra_ | ogra@panda1:~$ grep -i command /var/log/dmesg | 17:02 |

| ogra_ | ogra@panda1:~$ | 17:02 |
| rtg | smoser, so the first line is arch specific, arch/x86/kernel/setup.c. the second time its printed is from init/main.c which is generic | 17:02 |

| jjohansen | bjf: I have not been able to duplicate your apparmor test failure, can you send me some more info from those qa machines? | 21:09 |
| bjf | jjohansen: like what? i can open a bug and do the normal apport-collect. | 21:09 |
| jjohansen | bjf: yes please, I would also like the mount info | 21:10 |
| bjf | jjohansen: can do | 21:10 |
| jjohansen | bjf: also I have confirmed that the test suite is building locale versions of somethings for certain tests. Eg. the parser tests are done against a local built version. However the kernel tests do use the kernel and installed packages and are only locally building the test support programs | 21:47 |
| jjohansen | I have added it to our to do, to have all tests support testing against the installed packages | 21:47 |
| bjf | jjohansen: ack | 21:47 |
