08:44.52tasslehoffnevermind, I'll use tar instead. unpacking a tar.bz2 on a beagleboard takes quite some time :)

10:48.03bluelightningin the mean time I fixed some more build issues last night
10:48.34pb_whereabouts is meta-handhelds hosted, by the way?
10:48.44bluelightningpb_: it's not, that's the issue
10:48.50pb_ah, I see
10:48.54pb_do you want to have it on oe.org?

10:55.02lumagcolleagues, pxa270 boards (armv5te + iwmmxt) seems broken now due to big TUNE patches. Would it be suitable to add iwmmxt tune to oe-core, or it should live in meta-zaurus?
10:55.52pb_I think it would be ok to add to oe-core.
10:55.57lumagAsking about meta-zaurus, as I'm concerned about spitz.
10:56.02lumagpb_, ok
10:56.29pb_obviously I'm not the person who actually decides, but if I were you I would at least try submitting a patch and see what happens
11:05.21lumagant_work, do you have any recent reports regarding collie? (especially reg. CF cards)? I've tried running several kernels in qemu, but card was not fully detected. Do you have any info?

11:14.57ant_worklumag: hi
11:18.24ant_workI sent you te pending patch fixing iwmmxt
11:20.50ant_workabout cf, here a log http://pastebin.com/se3BMrmU
11:20.56Crofton|workhttp://pastebin.com/Cfa1VpLe
11:21.03Crofton|workthis is in the release branch
11:21.10Crofton|workI think I've seen it before
11:22.58lumagant_work, strange. I'll have to dig qemu then
11:23.12ant_workwait, read this too: http://lists.linuxtogo.org/pipermail/angstrom-distro-users/2011-August/003739.html
11:25.35lumagant_work, I'm using standard microdrive emulation which works with pxa-based zaurii. StrongARM PCMCIA unit is exactly the same as in PXA. So it's either some generic hw emulation problem (like caches or other stuff) or I don't know.
11:25.59ant_workah, I see
11:27.05lumagant_work, regarding iwmmxt: this is a bit strange. We already have a tune-iwmmxt.inc, but it IIUC will default for all packages to be built into iwwmxt feed.
11:29.16lumagMost probably we don't want that. I'd instead use armv5te feed/xscale optimization by default and only use iwmmxt for several packages (like mplayer)
11:31.30ant_workyes, if we want to share the same feeds
11:31.53ensc|ware iwmmxt binaries working with recent kernels?
11:33.22ant_worklumag: I asked RP but he ws very busy. Maye pb_ will tell us about  http://paste.debian.net/124948/
11:37.06ensc|wno.... iwmmmxt is still broken with 3.0

11:39.07lumagensc|w, any points for bugreport?
11:39.32ensc|whttp://comments.gmane.org/gmane.linux.ports.arm.general/11795
11:40.54ensc|wit's probably a bug in the kernel which does not restore iwmmxt registers on task switches
11:41.12ensc|w(extremly tricky and optimized code)
11:42.57lumagant_work, pb_ I'd suggest something like this: http://pastebin.de/18080
11:45.49ant_worklumag: seems right if we want to split pxa25x and pxa27x
11:46.00lumagensc|w, hmmm.

11:56.14lumagensc|w, have you tried pinging Eric Miao directly or via LAKML
11:58.04ensc|wafair, posting was cc'ed to them
12:01.49lumagensc|w, also you might be interested in debugging which paths the kernel chooses in kernel/iwmmxt.S, kernel/xscale-cp0.c, etc.
12:02.04ant_worklumag: as far as it concerns Zaurus, maybe only mplayer and ffmpeg are concerned

17:26.45Jay7lumag: about CF on Collie
17:27.10Jay7lumag: there was letter in angstrom-devel ML that have similar issues
17:27.42lumagJay7, I got my collie-qemu to boot from CF. But now I got another problem. Now with busybox, which looks like it drops root privileges incorrectly.
17:28.18lumagStrangely enough it affected only collie build.

17:29.51Jay7lumag: is login does not working?
17:30.11lumagno. It's stuck before that
17:30.20Jay7iirc, this was most known issue with bb :)
17:30.50lumagis not a bb fan.
17:32.40lumagCurrently I'm rebuilding collie image. If that won't help, I'll try rebuilding busybox.
17:32.50lumagBut currently the image is unusable :(
17:33.45lumagGot to go now.
17:33.47lumagBye!

19:11.55msmi've made a linux-yocto_3.0.bbappend
19:12.22msmand my preferred providor is linux-yocto
19:12.47khemwhat does it show as provider
19:13.14msmjust linux dummy
19:13.16khemif its not in COMPATIBLE_MACHINE for linux-yocto then it wont show up
19:13.31msmlet me look
19:13.36khemor something equivalent of COMPATIBLE_MACHINE
19:13.38msmthat was in the bbappend file at one point
19:13.57msmi had the line commented out… but i had it at one point
19:13.59khemmsm: its a regexp
19:14.15khemso you might have to append to it
19:14.51msmCOMPATIBLE_MACHINE += "(p2020ds)"
19:14.59msmhas that format changed any?
19:15.31khemno

19:23.54khemI dont have much idea
19:24.08khembut its kind of machine specific metadata
19:24.12khemfor that kernel
19:24.22khemmay be .config and patches if any I believe
19:24.46msmwhere does this live in the tree?
19:26.34msmi just can't see where else  to provide an override for my new machine
19:26.44msmgrepping through the source for mpc8315 for comparisoon
19:27.17khemits in kernel sources I think
19:27.31khembut it should first select the right kernel
19:27.39khemcan you do this

20:52.12gnutoomy question is: can you pass atags to a kexeced kenrel
20:52.20gnutoofor instance from /proc/atags
20:52.57Jay7hm.. shouldn't atags be in /proc/cmdline in the end?
20:53.11gnutoono it's a different thing
20:53.35Jay7can you show contents of /proc/atags?
20:53.44gnutoook
20:54.39gnutooI guess it contains not only the cmdline
20:54.44gnutoobut also other stuff
20:54.45gnutooright?
20:55.11Jay7seems I don't know..
20:55.38Jay7afaik, it was just other way to pass options to kernel
20:55.41gnutoofrom bug20:
20:55.45gnutoohttp://www.pastie.org/2316308
20:56.27Jay7last part looks like just kernel cmdline options
20:56.41Jay7not sure about first part (AT....)
20:57.02gnutoolet me find other atags
20:57.06Jay7better to ask some kernel guys :)
20:57.11gnutoo(other device)
21:00.16gnutooI start to remember
21:00.29gnutooI think there is also the board arch number
21:00.50gnutooall that I know is that it's the interface between the bootloader and the linux kenrel
21:01.24gnutooweb is very slow here
21:01.31gnutoo(far wifi AP + VPN)
21:02.20gnutoouboot documentation also say:
21:02.54gnutooThe maximum clock rate allowed depends on the silicon populated on the EVM.[...]This information is
21:02.57gnutoopassed to the Linux kernel using the ATAG_REVISION atag.
21:03.39gnutooarm/Booting seem to have something too in the linux kenrel documentation

21:05.43gnutoo*that
21:06.10Jay7gnutoo: s/kexecboot/kernel/ :)
21:06.46Jay7kexecboot does not pass atags to next kernel

21:07.58gnutoo(the kexec program)
21:08.21Jay7gnutoo: if atags just other way to specify kernel cmdline, it have no sense
21:08.33Jay7just add options to kexec --command-line or --append
21:08.36gnutooas I just said it's more than that
21:08.45gnutooit also specify machine number
21:08.49gnutooand a lot of stuff
21:09.05gnutoomy real problem is that since I made kexecboot work with n900
21:09.09Jay7well.. then it's out of my knowledge..
21:09.17gnutooan user complained that many stuff didn't work anymore in maemo
21:09.34gnutoo+ the fact that there is one minute delay between kexec -e and the kernel starting
21:09.42Jay7I don't know how to pass atags to kexec'ed kernel..
21:09.50gnutooso I wanted to try passing atags
21:09.53gnutooto see.....

21:11.04Jay7may be larsc on #qi-hw may say something
21:11.15Jay7but he is mips hacker, not arm
21:11.24Jay7and iirc atags are arm-specific
21:11.24gnutoohe's an arm hacker too
