| 03:22 | <ogra> vagrantc, well, i got it building an image and setting up everything fine, i havent booted any of my arm boards with it yet
| |
| 03:23 | <vagrantc> ogra: nice.
| |
| 03:24 | <ogra> the hard part will be to get redboot doung something like PXE or etherboot
| |
| 03:24 | *doing
| |
| 03:24 | <vagrantc> ogra: i'm working on a less elegant approach myself... just building a chroot and using qemu-system-arm to boot into it
| |
| 03:25 | and then installing ltsp-server and such from there...
| |
| 03:25 | <ogra> like my build-arm-rootfs script (now called project-rootstock) ?
| |
| 03:25 | <vagrantc> ah, perhaps.
| |
| 03:25 | <ogra> thats very very slow
| |
| 03:26 | debootstrap takes about 30-40 min for the second stage in it and hangs silently for a long time processing deps etc
| |
| 03:26 | <vagrantc> ah.
| |
| 03:27 | <ogra> thats what got me searching for an alternative and why i did that ugly hacked up qemu-arm-eabi thing :)
| |
| 03:27 | <vagrantc> i had done some debian-installer armel installs ... they took a long time indeed.
| |
| 03:27 | <ogra> which is as fast as x86 bootstrapping
| |
| 03:27 | sadly compiling isnt sped up with it ... gcc is still as slow as in qemu-system-arm
| |
| 03:39 | vagrantc, i surely hope we'll see these on the market for $100-$150 soon ;) http://www.blogcdn.com/www.engadget.com/media/2009/01/pegatron-free-029.jpg
| |
| 03:39 | they should be supported out of the box in karmic

| 06:11 | * ogra sighs about the existing beagleboard kernel .deb's ... | |
| 06:12 | <ogra> no nbd ... no cramfs :/
| |
| 06:15 | <vagrantc> ogra: well, after tweaking rootstock ... it seems to be what i was hoping for ... although it hangs at booting qemu-system-arm
| |
| 06:15 | <ogra> hangs ?
| |
| 06:16 | how exactly, where exactly ?
| |
| 06:16 | <vagrantc> after kernel boot ... loads the kernel, and then sits there
| |
| 06:16 | <ogra> did you change the bootoptions or qemu options ?
| |
| 06:16 | <vagrantc> nope
| |
| 06:16 | <ogra> it attaches to a serial console which is redirected to a fifo
| |
| 06:17 | you shouldnt even see any kernel messages
| |
| 06:17 | * vagrantc tries it again | |
| 06:18 | <ogra> if [ "$line" ] && [ ! "$(echo $line|grep 'Uncompressing Linux')" ] && \
| |
| 06:18 | [ ! "$(echo $line|grep 'unknown LCD panel')" ] && \
| |
| 06:18 | [ ! "$(echo $line|grep 'Restarting system')" ];then
| |
| 06:18 | echo ${line} >>$LOG 2>&1
| |
| 06:18 | <vagrantc> i think i got this one: echo "E: Second stage build in Virtual Machine failed !"
| |
| 06:18 | <ogra> it strips "Uncompressing Linux" and the subsequent messages
| |
| 06:19 | then your VM has paniced or so
| |
| 06:19 | <vagrantc> right
| |
| 06:19 | <ogra> is it using my kernel ?
| |
| 06:19 | or do you use your own
| |
| 06:21 | <vagrantc> i grabbed debian's kernel...
| |
| 06:21 | i'll try with yours
| |
| 06:24 | the disk modules might be modularized or something
| |
| 06:32 | ogra: do you know which other architectures that do or might support the binfmt-misc thing you're working with for qemu-arm-eabi
| |
| 06:32 | <ogra> no
| |
| 06:32 | try it out, ppc might
| |
| 06:32 | the prob are the non marching syscalls on different arches
| |
| 06:32 | *matching
| |
| 06:33 | <vagrantc> powerpc would be handy... as i could more easily get test machines ...
| |
| 06:34 | <ogra> if there are translation patches the userspace hacks might work the same as with arm
| |
| 06:34 | look in my source package, there is the binfmt_misc stuff to enable the interpreter ...
| |
| 06:35 | and the readme of binfmt-support has a bunch of info how to write postinst/prerm
| |
| 06:37 | * ogra curses | |
| 06:38 | <ogra> no squashfs, no nbd none of the usb NIC drivers in the beagleboard kernel debs
| |
| 06:38 | do you know if there is a debian beagle kernel deb anywhere ?
| |
| 06:38 | (from debian itself i mean)
| |
| 06:39 | oh, wow !
| |
| 06:39 | * ogra didnt know about http://packages.debian.org/sid/xserver-xorg-video-omap3 | |
| 06:39 | * vagrantc didn't either | |
| 06:44 | <ogra> root@osiris:/# apt-cache search omap3
| |
| 06:44 | xserver-xorg-video-omap3 - X.Org X server -- Omapfb display driver (NEON optimized)
| |
| 06:44 | ah, already in ubuntu
| |
| 06:44 | to bad there is no properly packaged kernel
| |
| 06:45 | grrr
| |
| 06:45 | CONFIG_CRAMFS=m
| |
| 06:49 | <vagrantc> build-depends on etherboot?
| |
| 06:50 | <ogra> it carries the whole qemu source patched inline
| |
| 06:50 | <vagrantc> ah
| |
| 06:51 | <ogra> so i copied qemus debian/control witout adjustment
| |
| 06:51 | its a real crappy package ...
| |
| 06:51 | good enough for a PPA :)
| |
| 06:57 | * vagrantc gives qemu-arm-eabi a whirl | |
| 06:57 | <ogra> :)
| |
| 06:58 | * ogra goes to find some food | |

| 08:14 | <vagrantc> ogra: qemu-arm-eabi worked like a charm!
| |
| 08:30 | man-db doesn't like it ... but whatever
| |
| 08:31 | talkhouli has quit IRC | |
| 08:39 | <vagrantc> ogra: to make things extra fun, i've been running qemu-arm-eabi under virtualbox :)
| |
| 09:05 | RobertBerger has joined #ltsp | |
| 09:10 | * vagrantc attempts to build a cross-arch ltsp chroot ... | |
| 09:17 | <ogra> heh
| |
| 09:17 | yeah, i saw the man-db moaning here as well
| |
| 09:31 | <vagrantc> well, ltsp-build-client is mighty slow...
| |
| 09:35 | though i suppose it'd work from ltsp-build-client directly with the build-arm-eabi-chroot script ...
| |
| 09:40 | <ogra> did you try my debootstrap change ?
| |
| 09:40 | it worked quite well here
| |
| 09:42 | <vagrantc> ogra: looks like your build-arm-eabi-chroot would work as a drop-in replacement for debootstrap
| |
| 09:42 | rather than re-implementing it in an ltsp-build-client plugin ...
| |
| 09:42 | <ogra> that too, though --arch would probably break
| |
| 09:42 | there is no check if it is in $@
| |
| 09:43 | not sure what debotstrap does if it gets it twice
| |
| 09:43 | <vagrantc> bet it works fine...
| |
| 09:43 | <ogra> QED :)
| |
| 09:45 | * vagrantc tests | |
| 09:45 | <vagrantc> no complaints yet
| |
| 09:45 | <ogra> yeah, i just wasnt sure what would happen with two different --arch values, but indeed thats impossible in ltsp-build-client
| |
| 09:46 | it gets the same one twice anyway
| |
| 09:46 | <vagrantc> well, my clunkier attempt of building a chroot, installing ltsp-server, and running the whole environment from within the armel chroot failed...
| |
| 09:46 | * vagrantc will try the simpler method. | |
| 09:52 | <vagrantc> ogra: there is *some* possibility that one would build armel on armel ...
| |
| 09:52 | ogra: the plugin doesn't account for that possibility...
| |
| 09:55 | litlebuda has joined #ltsp | |
| 09:55 | <vagrantc> ah, build-arm-eabi-chroot assumes that the second argument will be the install dir... so that doesn't work as a drop-in replacement ...
| |
| 09:55 | but shouldn't be hard.
| |
| 09:58 | * vagrantc patches it | |

| 19:08 | <Guest42772> Hi! I set up an ltsp server but I'm getting when I start a virtual diskless client (at the end of the loading process, just before the login screen) I get this error: mount:error mounting Server_IP:/opt/ltsp/i386 on /sysroot as nfs: Input/output error
| |
| 19:08 | Any idea?
| |
| 19:08 | RobertBerger has quit IRC | |
| 19:11 | <Guest42772> I think there is a problem with mount of nfs but I'm not a Linux expert... (Server is a Fedora 11 x86_64)
