11:25 NotRelevant I've managed to crash Linux on ARM (archlinux and xubuntu) with something like: grep -r -e ajadsoifjajfjasf /
11:25 NotRelevant as a regular user
11:26 NotRelevant can someone try it?
11:33 Coolgeek I'm not at home, so no :p
11:39 rabeeh NotRelevant: which distro?
11:45 wump if you're doing that as root you may be grepping in some scary device node, or sys entry
11:45 wumpus be sure to exclude those directories for a system-wide grep
11:58 NotRelevant rabeeh: I tried on ArchLinux and Xubuntu. And as regular user
15:06 rabeeh dv_: just figured out some issue with the 3.6.9 kernel on vmeta CPU utilization -
15:06 dv_ oh?
15:06 rabeeh http://www.solid-run.com/phpbb/viewtopic.php?f=11&t=1201&start=10#p6946
15:07 dv_ !
15:07 dv_ I will try this out ASAP
15:07 rabeeh listener->event_count = event_count;
15:07 dv_ btw: http://www.solid-run.com/phpbb/viewtopic.php?f=11&t=1241
15:08 rabeeh without that line, libvmetahal would poll a lot on an uncached registers that consumes the cpu to death
15:08 rabeeh dv_: i'v seen it. great work
15:08 rabeeh would you like me to unpack the packages.tar.gz for this job?
15:08 dv_ hmm I am not sure about it. you see, I am a bit worried about mirroring
15:09 dv_ all of these essential packages are hosted in only one place. would mirror not be a good idea?
15:09 dv_ or are there legal issues?
15:09 dv_ anyway, one big tarball is actually nice for services like dropbox
15:09 rabeeh no worries about legal
15:09 rabeeh we control the solidrun web site
15:09 dv_ um ... but then again, no wait, thats actually nonsense I just noticed.
15:10 dv_ keep the big tarball for now, I will give you a list of packages that would nice to have isolated out
15:10 dv_ *extracted
15:11 dv_ or would it be no problem to have the entire contents of the tarball lying around like that?
15:13 dv_ ah - now I see what my worries were. the big tarball contains .deb packages and other tarballs - but the libgfx is not compressed. you would have lots of headers etc. lying around. so perhaps unpack everything except the libgfx directory (or make a tarball out of it)
19:27 rabeeh dv_: 11% ?
19:27 dv_ yes
19:27 rabeeh 1080p?
19:27 dv_ just video, no audio decoding
19:27 rabeeh which bitrate
19:27 dv_ video is 1080p
19:27 rabeeh aah
19:27 rabeeh ok
19:27 rabeeh h.264?
19:27 dv_ but with audio its something like 20%
19:27 dv_ yes
19:27 rabeeh nice :)
19:28 rabeeh armhf
19:28 rabeeh right ?
19:28 dv_ http://www.sintel.org/download <- the mp4 1080p trailer
19:28 dv_ yes, armhf
19:29 dv_ with --march=armv7-a and -mfpu=vfpv3-d16
19:29 dv_ (-mfloat-abi=hard is added by OE automatically)
19:30 dv_ also: the display is currently configured at 1024x768. so the image is getting downscaled. i do not know how much of an impact this has.
19:35 dv_ note however that gst-ffmpeg (which is used for AAC audio decoding) isnt built with the iwmmxt code paths enabled, so it is slower than it could be. it is unfortunately not trivial to fix this, and other things had priority.
19:50 rabeeh the downscale is done by hardware anyway; there wouldn't be any performance impact
20:21 dv_ ah, okay.
20:22 dv_ as for the cubox-packages.tar.gz tarball, keep it on the page please, but yes, you can unpack it. but watch out for the libgfx/ folder, which unlike the rest of the contents of the big package is not in its own tarball.
20:29 dv_ oh, rabeeh , btw, what about xbmc? your fork is quite old now, and the arch PKGBUILD uses tons of patches: https://github.com/archlinuxarm/PKGBUILDs/blob/master/alarm/xbmc-cubox-git/PKGBUILD
20:29 dv_ so what do you know of the current situation? is vmeta support mainlined?
