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