2011-03-05 05:55 <Akiwiguy-iPad> Hello
2011-03-05 05:57 <wolfspraul> Akiwiguy-iPad: hi
2011-03-05 05:58 <Akiwiguy-iPad> And before anyone asks, yes, I'm on an iPad, and I would much rather have a nanonote in my hand with wifi and irssi. Because the nanonote is epic.
2011-03-05 05:59 <jow_laptop> ... as is the price for the wifi :D
2011-03-05 06:00 <Akiwiguy-iPad> I want to buy a nanonote. I'm saving up... Don't know how much it would be in New Zealand dollars.
2011-03-05 06:01 <Akiwiguy-iPad> Plus then I would need the wifi card.
2011-03-05 06:01 <Akiwiguy-iPad> How much is the spectec microsd wifi card?
2011-03-05 06:03 <wolfspraul> last I checked it was about 80 USD
2011-03-05 06:03 <wolfspraul> is it even still available? let me check...
2011-03-05 06:05 <wolfspraul> doesn't look like that. not available anymore, at least not at expansys.com
2011-03-05 06:05 <Akiwiguy-iPad> Oo, that's expensive
2011-03-05 06:06 <Akiwiguy-iPad> And darn.
2011-03-05 06:07 <wolfspraul> I may have a used one I could give you for free if you ordered a NanoNote :-) I have two left, need to check the details if you like.
2011-03-05 06:07 <wolfspraul> but then I'm a little worried - if wifi is so important to you the NanoNote may not be your best fit.
2011-03-05 06:58 <akiwiguy-iPad> Hello again.
2011-03-05 07:12 <wolfspraul> sorry gotta go, I read the backlog later...
2011-03-05 07:12 <wolfspraul> akiwiguy-iPad: if you don't catch me here, you can email me at wolfgang@sharism.cc
2011-03-05 11:02 <dvdk> help!
2011-03-05 11:02 <dvdk> my display went (almost) completely white. :/
2011-03-05 11:02 <dvdk> looks like gmenu2x sets some bad brightness/contrast settings
2011-03-05 11:02 <dvdk> (bootup messages display correctly)
2011-03-05 11:05 <dvdk> ah, ok, managed to set the gmenu2 "backlight" setting from the (now barely visible) gmenu2x settings app.
2011-03-05 11:06 <dvdk> was set to 100% (but not by me!), now back to 20
2011-03-05 11:27 <kyak> dvdk: :)
2011-03-05 11:28 <dvdk> hi kyak
2011-03-05 11:28 <dvdk> just trying to compile mplayer.
2011-03-05 11:29 <dvdk> but it doesn't show up in 'make menuconfig' nor .config :(
2011-03-05 11:29 <dvdk> ./scripts/feeds install MPlayer
2011-03-05 11:29 <dvdk> Installing package 'mplayer'
2011-03-05 11:29 <dvdk> maybe some dependency problem?
2011-03-05 11:30 <kyak> dvdk: hm.
2011-03-05 11:31 <dvdk> running make package/symlinks
2011-03-05 11:31 <dvdk> maybe it helps
2011-03-05 11:32 <dvdk> ok, seems to work now.
2011-03-05 11:32 <dvdk> strange
2011-03-05 11:32 <kyak> dvdk: does it show up in ./scripts/feeds search MPlayer?
2011-03-05 11:33 <dvdk> yes.
2011-03-05 11:33 <kyak> dvdk: are you using the latest feeds?
2011-03-05 11:33 <dvdk> but anyways, after make symlinks problem seems to have been fixed.
2011-03-05 11:33 <kyak> or you pin it to some svn revision?
2011-03-05 11:33 <dvdk> using feeds.conf supplied by openwrt-xburst (?)
2011-03-05 11:33 <kyak> ok, so it is pinned to some svn revision
2011-03-05 11:33 <dvdk> No rule to make target `package/MPlayer/compile
2011-03-05 11:34 <dvdk> hmm.
2011-03-05 11:34 <kyak> package/mplayer/compile :)
2011-03-05 11:34 <dvdk> i hate it
2011-03-05 11:34 <dvdk> :)
2011-03-05 11:34 <kyak> ok, i agree
2011-03-05 11:34 <kyak> we need to rename it
2011-03-05 11:34 <kyak> either all to MPlayer, or all ot mplayer
2011-03-05 11:35 <dvdk> thinks that all packages are othewise lowercase
2011-03-05 11:35 <dvdk> Debian seems to handle it that way
2011-03-05 11:36 <dvdk> renaming: sounds like 'tree conflict' once i try to commit :)
2011-03-05 11:37 <kyak> not a problem, make package/symlinks should fix it
2011-03-05 11:37 <dvdk> BTW working on an mplayer patch to dynamically load jz47xx_vid vidx
2011-03-05 11:38 <dvdk> going to commit to MPlayer/patches, that's why please wait with renaming :)
2011-03-05 11:38 <dvdk> or is it mplayer/patches?
2011-03-05 11:38 <kyak> dvdk: i see feeds.conf from openwrt-xburst mainly as a means to "pin" to some specific svn revision to be able to reproduce the build later. I myself always use the latest feeds.conf
2011-03-05 11:38 <dvdk> hmm.
2011-03-05 11:38 <kyak> it's mplayer/patches
2011-03-05 11:38 <dvdk> ok
2011-03-05 11:39 <dvdk> doesn't have the time to wait for package recompiles after updating feeds :)
2011-03-05 11:39 <dvdk> btw openwrt-xburst.git : always using the latest version
2011-03-05 11:39 <dvdk> actually:
2011-03-05 11:39 <dvdk> src-link qipackages ../../openwrt-packages
2011-03-05 11:39 <kyak> yep, using the latest version of openwrt-packages always
2011-03-05 11:40 <kyak> but not the latest version of openwrt-feeds :)
2011-03-05 11:40 <dvdk> kyak: btw noticed that most recent mplayer-svn can use ffmpeg's theora decoder (i.e. not libtheora).
2011-03-05 11:41 <dvdk> maybe that gives us some performance gain?
2011-03-05 11:41 <kyak> oh, that's god
2011-03-05 11:41 <kyak> *good
2011-03-05 11:41 <dvdk> well, without ffmpeg's simd assembly stuff, maybe difference is minor.
2011-03-05 11:41 <kyak> maybe we should use the latest mplayer from svn always..
2011-03-05 11:42 <dvdk> kyak: well, pin down a revisino and use that.  upgrade after testing that it works.
2011-03-05 11:42 <dvdk> some revisions (seldomly) have bugs
2011-03-05 11:42 <kyak> yeah
2011-03-05 11:42 <dvdk> btw: using svn download method might not work.
2011-03-05 11:42 <kyak> why not?
2011-03-05 11:42 <dvdk> mplayer does a ffmpeg git checkout from ./configure when using the version from svn
2011-03-05 11:42 <dvdk> yuck
2011-03-05 11:43 <kyak> heh. Maybe it can be cancelled?
2011-03-05 11:43 <dvdk> maybe manually package ffmpeg externally and use it as shared lib?
2011-03-05 11:43 <dvdk> to safe some flash
2011-03-05 11:44 <kyak> it's already packaged externally
2011-03-05 11:44 <dvdk> yeah, can be cancelled.  need to tell ./configure to use an external libffmpeg (i think)
2011-03-05 11:44 <dvdk> ok, then maybe autodetected already&fine.
2011-03-05 11:44 <kyak> we'll see :)
2011-03-05 11:45 <Jay7> kyak: I've pinged larsc yesterday wrt kexec
2011-03-05 11:45 <kyak> Jay7: yep, i've seen it
2011-03-05 11:45 <Jay7> but it was too late and I've fall asleep :)
2011-03-05 11:45 <kyak> hehe
2011-03-05 12:36 <qi-bot> [commit] David Kühling: mplayer: enable vidix driver subsystem; try to dynamically load jz47xx_vid.so http://qi-hw.com/p/openwrt-packages/9450286
2011-03-05 12:41 <kyak> dvdk: nice job! is it playable?
2011-03-05 12:43 <dvdk> hu?  no.
2011-03-05 12:44 <dvdk> it's just the hook that's needed to load the .so driver
2011-03-05 12:44 <dvdk> the .so driver is not even 5% done yet.
2011-03-05 12:44 <dvdk> (developing it separately on sourceforge)
2011-03-05 12:47 <kyak> dvdk: ok :)
2011-03-05 12:47 <dvdk> just having it in openwrt-xburst.git is going to make it easier for others to test and patch
2011-03-05 12:50 <kyak> sure
2011-03-05 13:29 <dvdk> why is it that mplayer compiled with ONFIG_DEBUG=y is so huge? (30MB package)
2011-03-05 13:29 <dvdk> s/onfig/config/
2011-03-05 13:29 <dvdk> shouldn't everything be stripped when the package is build (debuug info only left on the host for remote debug)
2011-03-05 13:30 <dvdk> installation takes hours
2011-03-05 13:32 <dvdk> ooops: ls /usr/bin/mplayer
2011-03-05 13:32 <dvdk> -rwxr-xr-x    1 root     root        92.7M Mar  5  2011 /usr/bin/mplayer
2011-03-05 13:32 <dvdk> 90MB!
2011-03-05 13:33 <kristian1aul> :/
2011-03-05 13:34 <Jay7> seems it have some promo video inside :)
2011-03-05 13:34 <kyak> hehe
2011-03-05 13:34 <kristian1aul> :p
2011-03-05 13:35 <kyak> dvdk: in fact, when i built minimal image with config.debug, i found it is more than 700 Mb :)
2011-03-05 13:35 <kyak> so it leaves symbols on target, too
2011-03-05 13:35 <dvdk> kyak: but it shouldn't.
2011-03-05 13:35 <dvdk> in fact ipkg is run with -g0 option.
2011-03-05 13:35 <dvdk> shouldn't it then strip debug info away?
2011-03-05 13:35 <Jay7> OE split debug info ingo -dbg packages
2011-03-05 13:35 <Jay7> s/ingo/into/
2011-03-05 13:36 <dvdk> yeah, but i do remote debug anways, and only need the debug info in the host build directory
2011-03-05 13:36 <kyak> dvdk: but maybe it thinks that you are going to debug on target?
2011-03-05 13:37 <dvdk> don't think that openwrt even supports that
2011-03-05 13:37 <dvdk> there is no other way to debug
2011-03-05 13:37 <dvdk> (no other debug option)
2011-03-05 13:37 <dvdk> ipkg-build -c -o 0 -g 0 /home/pub/spock/src/qi/openwrt-xburst/build_dir/target-mipsel_uClibc-0.9.30.1/MPlayer-1.0rc3/ipkg-xburst/MPlayer /home/pub/spock/src/qi/openwrt-xburst/bin/xburst/packages
2011-03-05 13:38 <dvdk> shouldn't that remove any debug info from the package?
2011-03-05 13:39 <kyak> maybe if you have CONFIG_PACKAGE_gdb=y, then openwrt fairly assumes that you are going to debug on target
2011-03-05 13:39 <kyak> have a look in data/qi_lb60/conf/config.debug, maybe it will help you.. I never finished it, but there are all debug options i could find in openwrt :)
2011-03-05 13:43 <dvdk> ah, but does package_gdb build a target 'gdb' package or just add mipsel-...-gdb to toolchain?
2011-03-05 13:43 <dvdk> i thought the latter
2011-03-05 13:43 <kyak> builds a target, i suppose
2011-03-05 13:43 <kyak> thereis CONFIG_GDB=y for want you want (probably)
2011-03-05 13:44 <dvdk> yeah, i only have config_gdb set, btw
2011-03-05 13:44 <kyak> what is your grep STRIP .config?
2011-03-05 13:48 <dvdk> CONFIG_NO_STRIP=y
2011-03-05 13:48 <dvdk> ouch
2011-03-05 13:48 <dvdk> :)
2011-03-05 13:49 <dvdk> auto-set by config_debug!?
2011-03-05 13:50 <kyak> hm-hm
2011-03-05 13:54 <dvdk> with config_debug set, i don't have the option to select 'sstrip' for stripping
2011-03-05 13:54 <kyak> dvdk: yep, CONFIG_NO_STRIP is autoselected by CONFIG_DEBUG. But it seems that you don't need the CONFIG_DEBUG.
2011-03-05 13:55 <dvdk> i need config_debug, else i only see symbols, not line numbers
2011-03-05 13:55 <dvdk> (?)
2011-03-05 13:55 <kyak> CONFIG_DEBUG enabled debugging symbols on target, you don't need that
2011-03-05 13:55 <dvdk> i now have config_debug & config_strip
2011-03-05 13:55 <kyak> CONFIG_GDB should work for you
2011-03-05 13:55 <dvdk> sure?
2011-03-05 13:55 <kyak> no :)
2011-03-05 13:56 <dvdk> i think it's correct now: config_debug to add '-g' to cflags, and use_strip to strip it from the package
2011-03-05 13:56 <dvdk> (had a silly crash-bug in my latest commit, btw, but only with -vo cvidix)
2011-03-05 13:56 <kyak> ah, so you still have a "strip" option
2011-03-05 13:57 <dvdk> yes, but toggleing config_debug seems to change strip, so you have to manually re-set strip afterwards
2011-03-05 13:57 <kyak> i think it should work this way :) you are right
2011-03-05 13:57 <dvdk> also 'sstrip' is not possible offered when config_debug, it seems
2011-03-05 13:57 <kyak> yeah
2011-03-05 13:58 <dvdk> btw accidentally committed make_flags-j4 with my last commit?
2011-03-05 13:58 <dvdk> using it here to speed up builds.
2011-03-05 13:58 <kyak> but i don't see that config_debug toggles the strip
2011-03-05 13:58 <dvdk> hmm.  but it definitely changed
2011-03-05 13:58 <dvdk> or did i toggle it accidentally?
2011-03-05 13:58 <kyak> it toggles the Strip arguments
2011-03-05 13:59 <dvdk> lets see whither mplayer is now back to sub-10MB range
2011-03-05 14:03 <dvdk> ok, mplayer is again small now
2011-03-05 14:04 <dvdk> let's see whether gdb still works
2011-03-05 14:04 <dvdk> works
2011-03-05 14:04 <dvdk> ok, it now runs code from jz47xx_drv.so
2011-03-05 14:05 <dvdk> ...and crashes :)
2011-03-05 14:06 <qi-bot> [commit] David Kühling: mplayer: fix silly crash bug with -vo cvidix (when jz47xx_drv.so present). http://qi-hw.com/p/openwrt-packages/81b4266
2011-03-05 14:12 <kyak> dvdk: cool :) having debugging capabilities is great, i realized it once again after connecting to Ben's serial console
2011-03-05 14:13 <dvdk> kyak: btw remote-debugging shared libraries is much more difficult, though
2011-03-05 14:13 <dvdk> gdb: add-symbol-file FILENAME ADDRESS
2011-03-05 14:15 <kyak> can you compile you library in mplayer ?
2011-03-05 14:15 <kyak> for testing purposes
2011-03-05 14:30 <dvdk> kyak: i do not want to: mplayer is too huge.  uploading 5MB over and over wears out my flash :)
2011-03-05 14:31 <dvdk> debugging via printf() should work for now.  there is some shared object debugging support in gdb, but it doesn't work for me currenlty
2011-03-05 14:34 <kyak> btw, you could try installing it SD card
2011-03-05 14:35 <dvdk> :)
2011-03-05 14:35 <dvdk> still turn-around time for 5MB copy is too long.  mplayer linking would also take too long for my taste :)
2011-03-05 14:36 <dvdk> ok, then lets see whether i can heuristically get some physical memory resources from user space
2011-03-05 14:36 <kyak> ok, my last proposal - try qemu :)
2011-03-05 14:36 <kyak> i found it extremely easy to use with openwrt malta(qemu) target
2011-03-05 14:42 <dvdk> kyak: can someone write a HW scaler emulation for qemu, please? :)
2011-03-05 14:44 <viric> dvdk: recent qemu uses GL for rendering
2011-03-05 14:44 <viric> isn't it?
2011-03-05 14:45 <dvdk> viric: was talking about the jz47xx hw scaler unit that i'm trying to program
2011-03-05 14:45 <viric> ahh
2011-03-05 14:45 <viric> you can use nfs over usb
2011-03-05 14:46 <dvdk> :)
2011-03-05 14:46 <dvdk> didn't think of that actually
2011-03-05 14:46 <dvdk> could also link to /tmp :)
2011-03-05 14:46 <kyak> too many options to debug things on Ben :)
2011-03-05 14:46 <dvdk> is off to lunch
2011-03-05 14:46 <viric>  /tmp? how would that help?
2011-03-05 14:49 <kyak> there's a tmpfs in /tmp
2011-03-05 14:49 <viric> in the ben?
2011-03-05 14:49 <viric> with 32MB of RAM?
2011-03-05 14:50 <kyak> tmpfs on /tmp type tmpfs (rw,nosuid,nodev,relatime,size=14108k)
2011-03-05 14:50 <Jay7> tmpfs is swap-backed
2011-03-05 14:50 <viric> really?
2011-03-05 14:50 <Jay7> so 32 + size of swap :)
2011-03-05 14:50 <Jay7> afaik, yes
2011-03-05 14:50 <viric> I didn't know it could use swap
2011-03-05 14:51 <kyak> i have a swap partition on SD card
2011-03-05 14:51 <viric> I remember it is an easy way to crash a system
2011-03-05 14:51 <Jay7> yeah, remove SD where swap resides :)
2011-03-05 14:52 <kyak> yep, remove SD and it will hang
2011-03-05 14:52 <viric> no, I mean filling a tmpfs when the system does not have enough memory
2011-03-05 14:54 <kristian1aul> argh!,  one hour lost because a missing rewind
2011-03-05 14:58 <viric> what do you rewind?
2011-03-05 15:01 <kristian1aul> a file descriptor
2011-03-05 15:01 <kristian1aul> i forgot rewind because i open it, seek to end (to get size) and let it like that.. '_'
2011-03-05 15:04 <viric> ah
2011-03-05 15:04 <steve|m> huh, can't you use fstat()?
2011-03-05 15:06 <kristian1aul> hehe, well fstat is a unix system call but not part of the standard lib i remenber
2011-03-05 15:06 <kristian1aul> i know it is posix but.. i want to stick ansi c for a while and see
2011-03-05 15:08 <kristian1aul> I had that discussion on my mind for some days (fstat or fseek)
2011-03-05 15:09 <kristian1aul> is a bit stubborn
2011-03-05 15:38 <qi-bot> [commit] kyak: add sound options to default config, so that it won't popup http://qi-hw.com/p/openwrt-xburst/04a194b
2011-03-05 16:04 <methril> wolfspraul, i did the first step :)
2011-03-05 16:04 <methril> wolfspraul, now waiting for the MMOne to arrive
2011-03-05 16:05 <kristianpaul> oh, congrats !
2011-03-05 16:06 <wolfspraul> methril: oh wow, fantastic!
2011-03-05 16:06 <wolfspraul> thank you for your trust in this project
2011-03-05 16:06 <methril> wolfspraul, thank you for bring all those fantastic projects to us
2011-03-05 16:06 <methril> ;)
2011-03-05 16:07 <methril> i'm going to announce in my blog (something new to said)
2011-03-05 16:08 <wolfspraul> excellent, thank you
2011-03-05 16:08 <wolfspraul> m1 needs a lot more stories to be told, but of course the first step is to get more hardware out
2011-03-05 16:08 <wolfspraul> so I cannot complain, we are slowly picking up
2011-03-05 16:09 <methril> i'm going to start with the dev env.
2011-03-05 16:09 <wolfspraul> you can hookup with xiangfu, who is also just starting (he got his m1 on Thursday)
2011-03-05 16:10 <wolfspraul> kristianpaul has a few weeks head start
2011-03-05 16:10 <wolfspraul> then there are others of course - the best place is the #milkymist channel
2011-03-05 16:11 <methril> i'm on the channel following lekernel progress :)
2011-03-05 16:12 <kristianpaul> think wolfspraul forgot nelson for the count ;-)
2011-03-05 16:12 <kristianpaul> Also he is in brazil
2011-03-05 16:13 <wolfspraul> no did not forget him, but he is very quiet/invisible. I tried to give methril some nicknames for people to ask, if he runs into problems.
2011-03-05 16:14 <methril> i've nelson in my contacts
2011-03-05 16:14 <methril> i talk with him sometimes
2011-03-05 16:14 <kristianpaul> (quiet/invisible) yeap
2011-03-05 16:18 <kristianpaul> methril: (ask) yeap i can help with my little experience with mm1 so far :-)
2011-03-05 16:18 <kristianpaul> Also i'm very patient :-)
2011-03-05 16:19 <methril> kristianpaul, thank you for the offer
2011-03-05 17:00 <kristianpaul> methril: what are you plans with milkymist?
2011-03-05 17:05 <methril> kristianpaul, help with linux port (mainly), but i would like to learn Verilog
2011-03-05 17:06 <methril> kristianpaul, and why not, experiment with FPGAs (maybe hw-radio,...)
2011-03-05 17:07 <kristianpaul> oh, wich part of hw-radio?
2011-03-05 17:09 <methril> i would like to deal with USRP like radio (and maybe i could do some boards to adapt it)
2011-03-05 17:09 <methril> i also would like to experiment the osmocon progress in our FPGA
2011-03-05 17:09 <methril> but it's a really long term
2011-03-05 17:12 <methril> kristianpaul, are you interested in HW-radio too?
2011-03-05 17:12 <kristianpaul> yeap
2011-03-05 17:12 <methril> what area?
2011-03-05 17:12 <kristianpaul> indeed, is long term
2011-03-05 17:13 <kristianpaul> GPS/GNSS
2011-03-05 17:13 <methril> nice
2011-03-05 17:14 <methril> i get impresse for the UNcube project
2011-03-05 17:15 <methril> and i see some of your blog posts :)
2011-03-05 17:15 <kristianpaul> funcube dongle?
2011-03-05 17:15 <kristianpaul> or also the satellite?
2011-03-05 17:15 <methril> http://www.funcubedongle.com/
2011-03-05 17:15 <methril> well the satellite
