[02:41] <jthomas_> Hello all
[02:42] <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
[02:43] <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
[02:44] <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
[03:24] <jthomas_> any help?
[07:17] <ppisati> morning
[15:16] <zul> ogra is there any documentation about putting ubuntu arm on a toshiba ac100?
[15:17] <ogra_> zul, yes
[15:18] <ogra_> zul, you got one ?!?
[15:18] <zul> ogra_: yep, christmas came early
[15:18] <ogra_> awesome
[15:19] <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
[15:20] <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
[15:21] <lilstevie> ogra_: it is ok on the galaxy tab
[15:21] <ogra_> yeah
[15:21] <lilstevie> but ubuntu is still better
[15:21] <ogra_> :)
[15:22] <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
[15:23] <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 zul, http://ac100.gudinna.com/README/ has outdated instructions for older images ...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
[15:26] <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
[15:27] <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 :)
[15:28] <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
[15:29] <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 ;-)
[15:32] <lilstevie> I really wish I could crack the 3D accel nut on the tab
[15:32] <lilstevie> unity would be win on the tab
[15:33] <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 ?
[15:34] <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
[15:35] <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
[15:36] <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
[21:28] <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?
[21:29] <sveinse> uhm, *cross compile Qt
[21:30] <sveinse> Dodgy network atm?
[21:54] <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?
[22:09] <Neko> hrw, nudge?
[22:20] <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?
[22:28] <hallyn> went ahead an dared to flash-kernel
[22:28] <hallyn> zul: how's your's treating you?
[22:30] <hallyn> zul: yay, i have a running container
[23:28] <zul> hallyn: missing some usb cables
[23:35] <hallyn> doh
[23:36] <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 :)
[23:37] <stgraber> hallyn: now we just need some ARM machines with fast I/Os to actually do something useful in containers ;)
[23:38] <zul> i actually need to see if openstack works first
[23:46] <hallyn> zul: jikes, good luck.  gonna use an external hd for that?
[23:47] <zul> nfs probably
[23:47] <hallyn> stgraber: that would make it easier to test a range of uses, yes :)
[23:47] <hallyn> zul: ah
[23:48] <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
