| jthomas_ | Hello all | 02:41 |
|---|---|---|
| jthomas_ | I am facing some problems when compiling instrumented arm assembly on ubuntu-arm | 02:42 |
| jthomas_ | I am trying to add some instrumentation code that does a simple printf | 02:42 |
| jthomas_ | but for some reason, I am getting a segmentation fault | 02:42 |
| jthomas_ | the interesting fact is that | 02:42 |
| jthomas_ | since printf requires the arguments to be put into r0 | 02:43 |
| jthomas_ | for whichever basic block that does not modify r0, the instrumentation works | 02:43 |
| jthomas_ | but when I instrument any basic block that modifies r0, either storing or loading the value of r0, then I get a segmentation fault | 02:44 |
| jthomas_ | any idea as to why this is happening | 02:44 |
| jthomas_ | any help would be great | 02:44 |

| zul | ogra is there any documentation about putting ubuntu arm on a toshiba ac100? | 15:16 |
| ogra_ | zul, yes | 15:17 |
| ogra_ | zul, you got one ?!? | 15:18 |
| zul | ogra_: yep, christmas came early | 15:18 |
| ogra_ | awesome | 15:18 |
| ogra_ | zul, https://launchpad.net/~ac100/+archive/ppa follow the link to my people account | 15:19 |
| zul | android sucks as an os ;) | 15:19 |
| ogra_ | yeah | 15:19 |
| ogra_ | currentl installation means to jump thought some hoops | 15:19 |
| lilstevie | zul: android serves a purpose | 15:20 |
| lilstevie | just not on tablet devices | 15:20 |
| ogra_ | i'm working on a proper installer that should be ready within this week | 15:20 |
| ogra_ | lilstevie, i would use it on a tablet ... but on nothing with a keyboard | 15:20 |
| lilstevie | ogra_: it is ok on the galaxy tab | 15:21 |
| ogra_ | yeah | 15:21 |
| lilstevie | but ubuntu is still better | 15:21 |
| ogra_ | :) | 15:21 |
| ogra_ | zul, start with http://developer.download.nvidia.com/tegra/files/os/tegra_froyo_20110207.run.gz it contains the nvflash utiliy you will need to flash the new kernel to the device | 15:22 |
| lilstevie | the easiest way to explain how android feels on the tab is like having a Ferrari that is locked out of 4th gear + | 15:22 |
| zul | ogra_: cool ll poke around | 15:22 |
| zul | and ask if i need help | 15:23 |
| ogra_ | zul, http://ac100.gudinna.com/README/ has outdated instructions for older images ... the commands are stil the same though | 15:23 |
| lilstevie | it works just not very very | 15:23 |
| gildean | zul: and if you want 3d, suspend and sound, you can follow my guide for .32 http://ac100.tunk.org/wiki/phh | 15:26 |
| ndec | ogra_: hi. i installed natty from the minimal FS. what's the meta package to install the full desktop? ubuntu-netbook or ubuntu-desktop? | 15:26 |
| zul | gildean: meh | 15:26 |
| gildean | but it has a bunch of nvidia-binaries and crap like that | 15:26 |
| ogra_ | ndec, up to oneiric its ubuntu-netbook | 15:27 |
| ogra_ | with this release we'll switch to -desktop on arm too | 15:27 |
| ndec | ogra_: thx | 15:27 |
| zul | im more interested in running other things other that desktop on it | 15:27 |
| ogra_ | gildean, zul surely wants to work with things like lxc | 15:27 |
| ogra_ | so he should use a sane kernel | 15:27 |
| gildean | ogra_: yeah, just mentioning :) | 15:27 |
| zul | ogra_: and normal server work loads ;) | 15:28 |
| ogra_ | yeah | 15:28 |
| ndec | ogra_: so on natty ubuntu-netbook should install the unity2D? | 15:28 |
| ogra_ | zul, go for my .37 image then, if you run into issues, just ping ... same goes for the kernel, if you are mising options or patches, tell me | 15:28 |
| ogra_ | ndec, both actually | 15:29 |
| zul | will do | 15:29 |
| ogra_ | unity as well as unity-2d | 15:29 |
| ogra_ | defaulting to 2d | 15:29 |
| ndec | ogra_: ok.. 1gb is being installed ;-) | 15:29 |
| lilstevie | I really wish I could crack the 3D accel nut on the tab | 15:32 |
| lilstevie | unity would be win on the tab | 15:32 |
| ogra_ | lilstevie, use unity-2d as we do in all arm images ? | 15:33 |
| lilstevie | ogra_: it fails | 15:33 |
| ogra_ | and florence so you have an android like kbd | 15:33 |
| ogra_ | it fails ? | 15:33 |
| ogra_ | bug number ? | 15:33 |
| ogra_ | :) | 15:34 |
| lilstevie | ogra_: not bug number | 15:34 |
| lilstevie | unless you want my own trac :p | 15:34 |
| lilstevie | I have zero accel | 15:34 |
| lilstevie | even 2D | 15:34 |
| ogra_ | and ? | 15:34 |
| lilstevie | gnome-classic is the only thing that doesn't put too much load on the cpu | 15:34 |
| ogra_ | my ac100 does only framebuffer too | 15:34 |
| ogra_ | but unity-2d is snappier than the 3D one on my intel laptop | 15:35 |
| lilstevie | your ac100 is also dualcore :) | 15:35 |
| ogra_ | true | 15:35 |
| ogra_ | but the cores are not actually used for graphics stuff | 15:35 |
| lilstevie | my software framebuffer is a bit fail | 15:35 |
| lilstevie | the SGX540 is meant to software accelerate without the need for the userland blobs | 15:36 |
| lilstevie | it is a bug my end though | 15:36 |
| lilstevie | the 2.6.32 sourcedrop from samsung had the most ugly unoptimized code | 15:36 |

| sveinse | I'm sitting here upgrading our target to natty, and I've hit this --sysroot thing. How can I compile Qt (not from deb source) with xdeb ? E.g. are there any tutorials of how to build with xdeb out there? | 21:28 |
| sveinse | uhm, *cross compile Qt | 21:29 |
| sveinse | Dodgy network atm? | 21:30 |
| Neko | if anyone's answering sveinse's questions, I'd also like to know how to get xdeb to work without actually packaging things as source packages... | 21:54 |
| Neko | is there something like a cross-debhelper? | 21:54 |
| Neko | hrw, nudge? | 22:09 |

| hallyn | ogra_: my update fetched your new kernel, buti'm not booting from it. how do i update it? flash-kernel with options, or some different command? | 22:20 |
| hallyn | went ahead an dared to flash-kernel | 22:28 |
| hallyn | zul: how's your's treating you? | 22:28 |
| hallyn | zul: yay, i have a running container | 22:30 |
| zul | hallyn: missing some usb cables | 23:28 |
| hallyn | doh | 23:35 |
| hallyn | well lxc is working for me, with the -2 kernel. will put off heavier testing till tomorrow | 23:36 |
| hallyn | (since today is holiday :) | 23:36 |
| stgraber | hallyn: now we just need some ARM machines with fast I/Os to actually do something useful in containers ;) | 23:37 |
| zul | i actually need to see if openstack works first | 23:38 |
| hallyn | zul: jikes, good luck. gonna use an external hd for that? | 23:46 |
| zul | nfs probably | 23:47 |
| hallyn | stgraber: that would make it easier to test a range of uses, yes :) | 23:47 |
| hallyn | zul: ah | 23:47 |
| hallyn | maybe i'll install lvm on a big usb stick so i can do some quick cloning :) | 23:48 |
| zul | bbl need to reboot to hopefully fix this freaking ipod | 23:48 |
