| RAOF | How about you? | 09:44 |

| ashwini | can we use setjmp and longjmp in kernel mode ?? or any equivalent method ? kernel version 3.6* | 11:15 |
| ohsix | for what? there are a bunch of mechanisms for jobs and threads | 11:16 |
| ohsix | if you can be specific abotu what you're trying to do i might be able to point out an alternative | 11:23 |
| ogra | The following NEW packages will be installed: | 11:28 |
| ogra | linux-headers-3.5.0-218 linux-headers-3.5.0-218-omap4 | 11:28 |
| ogra | apw, ^^^ what'S that ? (dist-upgrading my nexus7) | 11:29 |
| apw | ogra, hmmm just doing it now ? | 11:30 |
| ogra | well, i do my daily upgrade, so yes | 11:30 |
| * apw tries | 11:30 | |
| apw | ogra, while i think about it suspend/resume is bringing usb0 back up on the nexus, and upsetting NM on my desktop | 11:31 |
| ogra | apw, yep, NM will get fixed to ignore usb0 | 11:32 |
| ogra | at least for certain usb id's | 11:32 |
| ogra | so you can still set up usbnet manually by selecting the device from the indicator, but it wont attemopt autoconnection | 11:32 |
| apw | hmmm, i thought you were fixing that n7 side | 11:32 |
| apw | by not running the interface there unless you were using it | 11:33 |
| ogra | well, i was abouot to, but was told NM would be fixed | 11:33 |
| apw | that seems backwards, but i guess its not my problem | 11:33 |
| ogra | it does that for other usb connections too so it makes sense to have some filtering apparently | 11:33 |
| apw | libdatrie1 liblightdm-gobject-1-0 libthai-data libthai0 lightdm | 11:33 |
| apw | linux-headers-3.1.10-9 linux-headers-3.1.10-9-nexus7 | 11:33 |
| apw | linux-image-3.1.10-9-nexus7 linux-libc-dev python-imaging | 11:33 |
| apw | ubuntu-defaults-nexus7 ubuntu-settings unity-greeter | 11:33 |
| apw | ok didn't do that for me | 11:33 |
| ashwini | ohsix: what are the alternatives ? | 11:34 |
| apw | ogra, you didn't install the omap binary on there did you ? | 11:34 |
| ogra | i dont see ubuntu-drivers-common | 11:34 |
| ogra | i assume thats at fault | 11:34 |
| ohsix | ashwini: i don't know what you're trying to do | 11:34 |
| ogra | apw, nothing special installed that could pull it in, check if you didnt already have it installed, i'm probably not in sync with your upgrading | 11:35 |
| * apw notes that pretty much all use of setgjmp longjmp is wrong, in principle | 11:35 | |
| ohsix | and even the marginal uses won't hold in the kernel :p | 11:35 |
| apw | ogra, i got a nice shiney new kernel and no omap stuff, odd | 11:36 |
| ogra | weird | 11:36 |
| ogra | i'll dig on then | 11:36 |
| ogra | hmm, so purging linux-headers-3.5.0-218-omap4 leaves me with .... | 11:37 |
| ogra | The following package was automatically installed and is no longer required: | 11:37 |
| ogra | linux-headers-3.5.0-218 | 11:37 |
| * ogra scratches head | 11:38 | |
| apw | that makes sense i at least, that would be a dep of the other | 11:38 |
| apw | ogasawara, i have pushed a rebase to v3.8-rc6, booted and running here on 32 and 64 bit x86 | 11:38 |
| ogra | well, but it indicates that there was no dep that pulled in linux-headers-3.5.0-218 | 11:39 |
| ogra | thats the strange part here | 11:39 |
| apw | linux-headers-3.5.0-218-omap4 was the dep, you purged it | 11:39 |
| ogra | linux-headers-3.5.0-218-omap4 was not depended on by anything but its own meta though | 11:39 |
| apw | oh indeed, | 11:40 |
| === ricotz__ is now known as ricotz | ||
| ppisati | apw: did you check out the versatile support? | 11:50 |
| apw | ppisati, sorry i have lost some history, did you send me something to test? | 11:59 |
| apw | ppisati, otherwise, i tried hard to boot your kernel using qemu and options which seemed to be vexpress (not versatile) | 12:00 |
| apw | ppisati, and note it is vexpress | 12:00 |
| apw | ppisati, and i have failed to get it to do anything visible | 12:05 |
| apw | (your kernel == the one in the archive) | 12:05 |
| ppisati | apw: i sent a pull req yesterday about vexpress suport | 12:06 |
| ppisati | apw: vexpress = "ARM Ltd. Versatile Express family" | 12:06 |
| ppisati | apw: "enable ARM Versatile Express support" | 12:07 |
| ppisati | apw: To: kernel-team@lists.ubuntu.com | 12:07 |
| ppisati | apw: here is a precompiled version of kernel, initrd and rootfs with vexpress support: http://people.canonical.com/~ppisati/vexpress/ | 12:08 |
| apw | ppisati, thanks ... i completely phased on that | 12:08 |
| ppisati | apw: in the email there's the qemu command to boot it | 12:08 |
| apw | ppisati, will get into it and get it applied thanks | 12:08 |
| ppisati | apw: ack | 12:08 |
| apw | ppisati, in all cases you are just enabling the specified option on the subject line for the omap flavour... yes ? | 12:20 |
| ppisati | apw: yep | 12:20 |
| apw | ppisati, great, i have rebased and the configs are different enough to break them, but they are easy to recreate | 12:21 |
| ppisati | apw: ah yes | 12:21 |
| ppisati | apw: i forgot, master-next requires an updateconfig before applying my patches | 12:21 |
| apw | ahh ok | 12:21 |
| apw | ppisati, oh excellent, now they work :) | 12:22 |
| apw | ppisati, i was pushing the updateconfigs anyhow :) | 12:22 |
| ppisati | apw: you can test it with my rootfs, but beware that the NIC drievr is a module | 12:24 |
| ppisati | apw: so you need to install the kernel .deb in the rootfs to get networking | 12:24 |
| ppisati | apw: ah, and my rootfs is linaro :P | 12:25 |
| ashwini | any pointer for setjmp_pre_handler ?? How to use or any type of documentation ?? | 12:25 |
| * henrix -> lunch | 12:29 | |
| apw | ogasawara, i have applied ppisati's versatile stuff and am testing it now | 12:36 |
| * ppisati -> goes to find some food | 13:04 | |
| ogasawara | apw: ack, thanks. I think I'll prep another upload for today then. | 13:45 |
| apw | ogasawara, i'll let you know when its 'good' | 13:49 |
| apw | ogasawara, the rc6 testing went well on x86 | 13:51 |
| ogasawara | apw: good, I'm gonna test it all on my kit here as well | 13:53 |
| arges | ogasawara: fyi. wireless patch c3e5d718 on my raring laptop has fix issues so far. is this included in rc6? | 13:54 |
| ogasawara | arges: it should be, but let me double check | 13:54 |
| apw | v3.8-rc6~20^2~10^2^2~7^2 | 13:55 |
| apw | arges, looks to be yes | 13:55 |
| arges | thanks, i should be less lazy : ) | 13:55 |
| apw | yes, you should :) | 13:55 |
| apw | ppisati, ack | 13:55 |
| apw | if i can get a console i will be amazed | 13:56 |
| ppisati | apw: you should have a console | 13:56 |
| apw | ppisati, my panda(?) is hanging left right and centre with these kernels | 14:02 |
| ppisati | apw: scheduling while atomic? | 14:04 |
| apw | ppisati, no way to tell, it just hangs | 14:05 |
| apw | though the scheduling whilst atomics in there may well be indicative | 14:05 |
| ppisati | apw: i tested my patches on panda and it was ok | 14:05 |
| apw | ppisati, and my board is hanging ... a lot ... but i use ipv6, a lot | 14:06 |
| ppisati | apw: lemme try master-next tip | 14:06 |
| apw | so perhaps there is a connection | 14:06 |
| apw | or perhaps my board is dying, how the hell to tell | 14:06 |
| apw | ppisati, i have no serial console output from my kernel | 14:06 |
| ppisati | apw: that's weird | 14:07 |
| apw | and maybe that would be telling me something, whats the runes to get that working | 14:07 |
| apw | ppisati, no i think its config rather than anything else | 14:07 |
| apw | i get uboot on there | 14:07 |
| ppisati | ok so | 14:07 |
| ppisati | flag@flag-desktop:/media$ cat preEnv.txt | 14:07 |
| ppisati | bootargs=ro console=tty0 console=ttyO2,115200n8 debug earlyprintk=ttyO2,115200n8 root=UUID=be44da86-b040-478b-9ce9-4e99e29c2872 | 14:07 |
| ppisati | and media is my /dev/mmcblk0p1 | 14:07 |
| ppisati | you probably just need to add: "console=tty0 console=ttyO2,115200n8 debug earlyprintk=ttyO2,115200n8" and delete "quiet splash" | 14:08 |
| apw | ppisati, ack | 14:09 |
| apw | will have a look | 14:09 |
| apw | so your versatile works a lot better than it did before | 14:09 |
| apw | though on my image it implodes | 14:10 |

| ppisati | apw: that would explain it | 14:19 |
| apw | it would? | 14:19 |
| ppisati | apw: well, could be a bug on qemu | 14:19 |
| apw | ppisati, i think its much more likely my fault to be hones | 14:19 |
| apw | i'll confirm with your rootfs | 14:20 |
| apw | if yours blows too then its qemu if not, i don't care ;) | 14:20 |

| apw | ppisati, ok your image boots fine with my -4 kernel .. | 14:37 |
| apw | so ogasawara that looks good in my testing | 14:37 |

| ppisati | apw: can you upload your img somewhere? i should try to roll my own ubuntu BTW | 14:43 |
| apw | ppisati, its just the debian one | 14:47 |
| apw | ppisati, i assume in theory if i dd off my panda with this -omap installed | 14:48 |
| apw | ppisati, that would make a valid image | 14:48 |
| ppisati | apw: yep, should be | 14:48 |
| apw | ppisati, this debian image isn't worth worrying about, its an old armel one even | 14:48 |
| apw | so ... we are better off making a new one off one of these pandas or someething | 14:48 |
| apw | ppisati, the serial job isn't working on this board even though echo >/dev/ttyO2 works | 14:50 |

| apw | ppisati, as in the getty is not throwing onto it | 14:51 |

| apw | but i think it is broke ... debugging it now | 14:53 |
| * ppisati still uses /etc/init/ttyO2.conf | 14:53 | |
| apw | ahh it doesn't work if you have console=tty0 console=SERIAL | 14:53 |
| apw | stupid thing | 14:54 |
| apw | fixed | 14:54 |
| apw | ppisati, http://paste.ubuntu.com/1597104/ feels like the last thing it said before locking up | 14:56 |
| apw | ppisati, and 100104 is like LIST_POISON or something isn't it? | 14:57 |
| ppisati | yes | 14:58 |
| apw | i'll let it do it again and see if it behaves the same | 14:58 |
| apw | ppisati, even with these stability problems this is a good step | 15:03 |
| ppisati | apw: i think it's ipv6 related because | 15:05 |
| ppisati | apw: time DEB_BUILD_OPTIONS=parallel=4 fakeroot debian/rules binary-omap4 | 15:05 |
| ppisati | apw: and it's still compiling | 15:05 |

| apw | we shall see | 15:13 |
| apw | ogasawara, have you wrapped the kernel yet? we might want seth's thing | 15:15 |
| ogasawara | apw: heh, I was literally about to ping sforshee about that | 15:16 |
| ogasawara | apw: I'd prepped the upload but failed to see his patch till after | 15:16 |
| ogasawara | apw: I was going to redo it to include it | 15:16 |
| apw | that is annoying when it happens | 15:16 |
| ogasawara | apw: so I'm kicking off new builds | 15:17 |
| sforshee | ogasawara, it's not critical, but it would be helpful for helping me debug a wireless issue that bjf has been seeing | 15:17 |
| apw | if it it pushed, i can do the same and boot test them | 15:17 |
| ogasawara | apw: I'm applying it right now and will push, gimme 2min | 15:17 |
| sforshee | if it's too much of a hassle it can wait until next time | 15:17 |
| ogasawara | sforshee: nah not much trouble, I'll squeeze it in | 15:18 |
| apw | the more we have the less bad i feel about it being 36 hours after the last one | 15:18 |
| ogasawara | indeed | 15:18 |
| apw | ogasawara, i don't know if you followed along, but this -omap now supports omap3,4, some imx6 thing, and vexpress (for qemu) all out of the same bits | 15:19 |
| apw | pretty good start me thinks | 15:19 |
| ogasawara | apw: yep, I saw the chatter, it's sweet! | 15:19 |
| * apw is going to make a qemu'able image from his omap board when this test is done | 15:20 | |
| ogasawara | apw: ok, pushed to master-next what I'm intending for the upload | 15:21 |
| ogasawara | apw: I've not yet tagged or reset master | 15:22 |
| ogasawara | apw: will do so after my builds and testing are good | 15:22 |

| ocdtech | What do these errors mean? http://dpaste.com/903980/ | 17:12 |
| sforshee | ocdtech, it means there are some coding errors in the kernel you're trying to build | 17:19 |
| === zequence_ is now known as zequence | ||
| ocdtech | sforshee: are the error in the code or the .config ? | 17:24 |
| sforshee | ocdtech, the code | 17:25 |
| ocdtech | my source is the 3.2.37 stable from kernel.org how would errors get introduced? If run make -i will it complete? I know the kernel may not run if it does. | 17:26 |
| sforshee | ocdtech, you haven't modified the code at all? Applied any extra patches? | 17:27 |
| sforshee | it's possible the errors only show up under certain configs, but it definitely looks like code errors to me | 17:27 |
| ocdtech | sforshee: I applied only one patch from a known good tarball. It was used on another machine in my office a few weeks ago. | 17:29 |
| sforshee | ocdtech, to the same kernel version? If it was a different kernel version then it may contain changes incompatible with 3.2.37. | 17:30 |
| ocdtech | sforshee: he was using 3.2.23 and the patch worked fine, but I can't find source for 3.2.23 | 17:31 |
| ocdtech | sforshee: think that's the problem? | 17:32 |
| apw | ocdtech, well the simple test is to unapply the patch and see if it compiles without, if so then its the patch | 17:32 |
| ocdtech | apw: I didn't know I could do that. Off to google I go! | 17:33 |
| apw | ocdtech, patch -R undoes patch | 17:33 |

| apw | not likely | 17:48 |
| apw | ocdtech, though i can also say that 3.2.37 built just fine in our mainline automated builds | 17:49 |

| sforshee | ocdtech, I'm looking at 3.2.37 and there shouldn't be any attempts to initialize a field named deadline | 17:54 |
| ocdtech | sforshee: is it refering to the I/O scheduler? | 17:55 |
| sforshee | sforshee, this is initialization of the task_struct | 17:58 |
