#qi-hardware IRC log for Wednesday, 2010-09-08

Action: Textmode scratches head, and wonders where he put the xburst toolchain.01:44
bartbesif you built it you should be able to find it01:45
bartbesit's huge01:45
Textmodeyes, yes it it.01:47
Textmodeah, it was on a seperate partition, which wasn't mounted.01:48
Textmode(and yes, it it the only thing on that partition.)01:49
bartbesand that partition is now full01:59
bartbesand it's multiple TBs01:59
Textmodebartbes: practically, 130mb free. :P02:03
tuxbrainurandom still arround in this channel?03:01
xiangfuwolfspraul: Hi03:20
wolfspraulah hi.03:20
wolfspraulI setup a separate buildhost machine, fidelio.qi-hardware.com03:20
wolfspraulif you send me your public key I give you root access and create a user account too03:21
xiangfuwolfspraul: great.03:21
wolfspraulit's a very cheap server, only 29 EUR / month (on sale :-)) so it's not very powerful but I think still well suited as a build server. 64-bit athlon, 300gb raid-1 disk, etc.03:22
wolfspraulanyway before we upgrade hardware, we should first understand our real needs, so I thought I start with this03:22
wolfspraulI can also use it as a safe sandbox for things like the schematics diffs generation03:22
wolfspraulanyway it's there now. I am running a make with config.full_system right now (in my user account)03:23
wolfspraulof course anybody else who wants to build qi related stuff is welcome to use it too03:23
wolfspraulxiangfu: so do you want an account?03:24
wolfspraulI may have your public key already somewhere, can copy from there...03:24
xiangfuwolfspraul: how much time build the openwrt in this server.03:24
xiangfuwolfspraul: I can send you again. it's ok.03:24
wolfsprauldon't know yet [build time]03:25
wolfspraulwe can also use it later to build the entire world (all packages), which we need to do because upstream won't turn off patented codecs in their builds03:25
TextmodeI've forgotten how to use the xburst toolchain :/03:26
xiangfuwolfspraul: http://www.openmobilefree.net/other/downloads/tmp/id_rsa.pub03:27
wolfspraulxiangfu: ok try to logon, should work now, 'xiangfu' user also created already03:28
wolfspraulxiangfu: so what's the latest status in terms of image building?03:29
wolfspraulone build I had broke at compiling vim...03:29
wolfspraulcannot stat ... /vim_normal : no such file or directory03:30
wolfspraulneed to look into it03:30
xiangfuwolfspraul: compile fine.: http://www.openmobilefree.net/other/downloads/NanoNote/BEN-LATEST-COMPILE/03:30
xiangfuwolfspraul: I think we should use static package SVN revision. not always upload to the latest version.03:31
wolfspraulhow does openwrt backfire do it?03:32
wolfspraulwe need to be careful to not overload us with too much work03:32
wolfspraulopenwrt backfire will always use the latest version for packages? I cannot imagine that.03:34
xiangfuwolfspraul: definetly not. because they not release backfire every.03:35
xiangfufor example we release the 2010-08.26. and the 2010-08-26 use the package revision is r123456 (for example).03:36
xiangfuthen we release a script file  checkout the package revision to r123456 not the latest version.03:37
xiangfuthis script file release with image.03:37
wolfspraulstill don't understand - how does backfire handle this?03:38
wolfspraulwhere do the package revisions for backfire come from?03:39
xiangfuhmm.. the backfire 10.03-rc3. is release at #1 2010-04-03 02:32:44,03:43
wolfspraulxiangfu: look at the files here: http://downloads.openwrt.org/backfire/10.03.1-rc3/xburst/03:46
wolfspraulactually I am wondering how well those images work :-)03:46
wolfspraulwe cannot use them because they include patented codecs03:46
wolfspraulbut they are definitely being built, and it's built in the way openwrt handles the 'backfire release' (whatever way that is)03:47
wolfspraulso how are these images built? how can we only derive from these images, without having to worry about each individual package revision?03:48
wolfspraulmaybe they don't have any packages from feeds at all? feeds are not included in the release system? the rootfs tarball is only 1.5 MB...03:49
xiangfuthe backfire only have thress packages repos:03:52
xiangfuwe have six package repos.  see openwrt-xburst/feeds.conf03:53
xiangfuthe .config can select or disclect which packge to build or not. but it can not select the package version.03:55
xiangfuso if user want build a backfire image in his own pc. he much checkout the packge revision to the date : Aug-27. (like the link you send to me"03:56
xiangfunot the last revision.03:56
wolfspraulit works with dates? you cannot pin some revision in the package feed repositories?03:57
xiangfuthere are Aug-27 have five commit: @22823 ~ 22818. I don't know which one is for Aug-27 release. but definetly one of them.03:58
xiangfuthere are five commits in Aug-27, in openwrt/packge svn.03:59
xiangfuthere are five commits at Aug-23 in openwrt/package svn server. (sorry for my bad english :(04:00
xiangfuhere is the revisions history: https://dev.openwrt.org/log/packages04:00
xiangfuAug-27. is about 12 days ago.04:02
wolfsprauldon't understand, but doesn't matter04:04
wolfspraulhere are the backfire packages http://downloads.openwrt.org/backfire/10.03.1-rc3/xburst/packages/04:06
wolfspraulwhere do those package versions come from?04:06
wolfspraulI'll just go through the compile process to understand it...04:06
wolfspraulxiangfu: what's the result with your latest image then? what works, what doesn't work?04:07
xiangfuwolfspraul: sorry. not test yet. will test it today.04:08
xiangfuwolfspraul: I cann't find out which revision of openwrt.org/backfire/10.03.1-rc3/xburst/packages/ use.04:12
xiangfuthe package revision is output by "./scripts/feeds update" when he/she compile.04:13
wolfspraulthat means our images are not reproducible04:13
wolfspraulbecause we discard the versions of the individual packages? well we are publishing a BUILD_LOG file so it's probably in there, but is there any effective way then to re-create our release images? maybe not...04:14
xiangfuwolfspraul: the BUILD_LOG is make outout. not include the ./scripts/feeds output.04:15
xiangfuwolfspraul: but we can check you current packge revison by .:04:15
xiangfucd ./feeds/packages && svn info04:15
xiangfuwe can.04:17
xiangfufor example: if you want reproduce my last build. you should:04:18
xiangfucd ./feeds/packages && svn co -r 2296804:18
xiangfunot run "./scripts/feeds update -a" . because when you use "./scripts/feeds udpate -a" it will update feeds/package to r2297604:19
xiangfuI will try to write a script file for reproduce  openwrt release image.04:21
tuxbrain2bartbes: is the lua/love in the qi repo yet?08:13
qwebirc75230hi  some one in here?08:36
wolfspraulwow that was quick08:42
kristianpaulwolfspraul: i want compile openwrt stuff in your server09:40
wolfsprauldo I have your public key somewhere?09:40
kristianpaulmy cmputer is so slow righ not and still building since yday at night...09:40
kristianpaulwolfspraul: projects09:40
wolfspraulwell I'm not sure the server is much faster :-)09:40
kristianpaulwolfspraul: indefero09:40
wolfspraulit's a single core athlon09:41
wolfspraulI am building config.full_system right now, started maybe 5h ago, still running09:41
kristianpaulgmm as my computer09:41
wolfsprauloh it's definitely good to have a server09:41
wolfsprauluse screen, leave stuff running09:41
kristianpaulyesh !09:41
wolfspraulwe need to ramp up the servers and builds anyway09:41
kristianpaulsure actually my dekstop coputer is powerfull than my web/blog/mail/other stuff server..09:42
kristianpaulbut i cant do all by the comannd line (may i need reconsider that) when building openwrt..09:42
kristianpaulwell lets wait your to see your performance timmings09:43
Action: kristianpaul need new server a lab PSU ohh my god so much money !!!09:43
wpwrakgaah. way too much beer for a tuesday :-(09:44
wpwraktuxbrain2: nice video !09:45
kristianpaulwolfspraul: that SDK you mentioned i hope will save time for this building, also i asked in openwrt-dev and ther is not such us auto build package thing09:45
wolfspraulkristianpaul: account name 'kristianpaul' ok?09:45
kristianpaulwolfspraul: well ok09:46
wolfspraulthere is also something called 'image builder' - it's big but can save lots of time09:46
wolfspraulnot good? what do you prefer?09:46
kristianpauli dont sait it is not good :)09:46
kristianpauli actually was hoping some auto packaging tool (i mean from source)09:47
kristianpaulbut i know is ask too much09:47
kristianpauland risk quality in packages09:47
kristianpaulwpwrak: morning !09:47
kristianpaulwpwrak: so mmap is dangueros? :)09:48
wpwrakkristianpaul: it's powerful. with great power comes great responsibility :-)09:49
tuxbrain2wpwrak: you passion for beer another reason to love you :), thanks  for the grettings master :)09:49
wpwraktuxbrain2: still twiddling my thumbs with UPS/mail boxes. i copied you on the retransmission. (the first one, went only to them, without copy)09:50
wolfspraulkristianpaul: try it out kristianpaul@fidelio.qi-hardware.com09:51
wolfspraulalso added you to root's authorized_keys09:51
wpwraktuxbrain2: ah, wish the girls would love me for the beer :) usually, they just give my belly a critical glance09:51
wolfspraulmy plan for this server is 'buildhost', let's say 'medium security' :-)09:52
wolfspraulso I see the whole thing as a big /tmp folder09:52
wolfspraulwe can use it as a sandbox to run scripts like the schematics diff too, and similar stuff09:52
wolfspraullike a 'cpu + /tmp storage in the cloud'09:53
wolfspraulplease don't store any valuable data on it, I am not doing any backups09:53
wpwraklet's see if they're already inefficient enough to bring the machine to its knees :)09:53
tuxbrain2wpwrak: I will see the mbe guy today I will comment, regarding the girs... well you know you have allways a bald, fat beared man waiting for you in spain :P09:53
wolfspraulalso I will be more generous on that machine playing with testing, even unstable packages. for example I am on squeeze right now.09:53
wpwraktuxbrain2: thanks. this will improve my ability to deal with rejection ;-))09:54
kristianpaulwpwrak: i'm in09:56
wpwrakwolfspraul: bte, the scripts should be good to use now in their new home. i did ben-wpan and xue without trouble. Makefile shows you how to use things, including some environment variables to make make the generated Web page nicer.09:56
kristianpaulwolfspraul: ^09:56
kristianpaulwpwrak: but is okay used it?, i just dont want end doing a kernel module that will drop me perfomance, what are those responsabillites btw?09:57
wpwrakkristianpaul: you just need to get the registers right. it's not more dangerous than writing anything that lives inside the kernel.09:59
kristianpaulwpwrak: sure i'll take care, actually i just want readdata most of the time, may be let a led for ocasional debugging10:00
wolfspraulkristianpaul: I updated the documentation, http://en.qi-hardware.com/wiki/Server_setup#fidelio.qi-hardware.com10:00
wolfspraulit also describes the function of the server, lack of backup etc.10:01
kristianpaulwolfspraul: cool :)10:01
wpwrakkristianpaul: for users, it has the drawback that they need to run it as root and that there's no useful privilege separation (if you care about such things). on the technical side, you also don't have access to interrupts.10:01
wolfspraulfeel free to use the machine aroudn the clock, if you have any useful load for it I'm glad to help10:01
wpwrakwolfspraul: you should have named the server "dirt" or such :)10:01
kristianpaulis not that defauklt (running root ) in openwrt wpwrak ?10:02
wolfsprauljust please remember /tmp etc. - no backups, the way it's run downtime may be unavoidable sometimes10:02
wpwrakkristianpaul: dunno. i always run things as root. if you add up all the time it takes you to go back and put a sudo in front of whatever you're trying to do, i'm sure there's a whole year of your life you're wasting :)10:03
kristianpaulwpwrak: i'm not sure how usefull will be get 2millions interrupts every second..10:03
kristianpaulnot for me :)10:03
wpwrakkristianpaul: 2 MHz interrupt frequency .. in your dreams :)10:03
kristianpaulwpwrak: i use sudo on other things i just notice opnewrt dotn encorage me to do it so10:04
kristianpaulsudo and non privileges users.10:04
wpwrakwolfspraul: now we just need a bit of simple web space, somehow connected to "projects" :)10:04
wolfspraulyou mean for the schematics diffs?10:06
wolfspraulkristianpaul: I will also do ipv6 tests on this server. the dns already has a aaaa record for it, and a ipv6 reverse dns is equally setup10:07
wolfspraulso before going live with ipv6 stuff on other servers, I'll do experiments on this one10:07
wolfsprauljust fyi10:07
wpwrakwolfspraul: for anything that needs to go to the web. e.g., all the stuff in www.almesberger.net/misc/ben/10:08
wolfspraula /64 ipv6 subnet is assigned to the server and packages should be routed to it, although I have never tried and don't know what would happen with such packages once they reach the kernel :-)10:08
wpwrakwolfspraul: manually uploading things into the wiki is just way too painful10:08
kristianpaulwow it is fast bandwich10:09
wpwrakkristianpaul: how lousy is the cpu ? :)10:09
kristianpaulthat erlly save me time10:09
wpwrakkristianpaul: and how much RAM ?10:10
kristianpaulwpwrak: oad average: 0.99, 1.10, 1.0510:10
wolfsprauls/packages/packets/ (building and writing at the same time is too much for me I guess)10:10
wolfspraulon the buildhost? just 2 GB. I just got the cheapest server on sale, 29 EUR / month.10:11
qi-bot[commit] Xiangfu Liu: update gmenu2x version to the last commit http://qi-hw.com/p/openwrt-packages/ec1da6d10:11
kristianpaulwpwrak: #  AMD 64 3700+, 2 GB DDR400 RAM, 2 x 300 GB SATA (Software-RAID 1)10:11
kristianpaulwpwrak: sale? but you pay i moth by moth how is that?10:11
wpwrakwolfspraul: cpu looks decent. memory is a bit on the low side, though. lots of ram reall helps to speed up things.10:12
Action: kristianpaul interested10:12
wolfspraulyeah but they have special etc. they need to fill their new mega datacenters...10:12
wolfspraulwpwrak: please explain me in more detail what you mean with 'web space attached to projects'10:13
kristianpaulwpwrak: so planning have loop filesystem in ram?10:13
wolfspraulwhat I planned to do was the schematics diff stuff, that is clear. the url needs to be relative to project names somehow, it all should work automatically for any kicad project10:13
wolfspraulwe already have /people/ storage on downloads, just to dump stuff on a server. but you have that at almesberger.net too, no?10:14
wolfspraulso what more do you mean?10:14
wpwrakwolfspraul: oh, just a place to put the sort of stuff i currently keep on my server. checking it into git often doesn't give us the right kind of access from the web (see the feature request we had)10:14
wolfspraulkristianpaul: let's use this machine first, we can always upgrade, and computing power gets cheaper...10:14
wpwrakwolfspraul: ah, people sounds good. do i have that ?10:15
wolfspraulthe raid1 will also slow it down, probably, for build style loads (too many writes)10:15
kristianpaulwolfspraul: sure i will use at much i can10:15
wolfspraulyou prefer DAV or ssh/scp?10:16
wolfspraulif you want DAV, email me the password you want10:16
wpwrak(raid1) you can either make the storage system fast or you can add ram until you don' care about the disks. the latter tends to be cheaper for moderate loads :)10:16
wolfspraulotherwise I add your pubkey10:16
wpwrakdefinitely ssh/scp :)10:16
wpwraktuxbrain2: mboxes woke up. pickup should happen today.10:18
wolfspraulwpwrak: do you prefer werner or wpwrak for your people folder?10:27
kristianpaulwolfspraul: how i do crate a project in the qi indefero?10:34
kristianpauli think is time start uploading some code :)10:34
wolfspraullet me give you super powers :-)10:36
kristianpaulwee :)10:36
wpwrakwolfspraul: "werner" would be good10:37
wpwrakkristianpaul: now you can write something with mmap there, too :)10:38
wolfspraulkristianpaul: I made you 'staff' for now, there is also admin but I need to lookup how to enable that.10:38
wolfspraulwith staff rights you can definitely create projects10:38
wolfspraulI am kind of pushing out to add a 'create project' web form because I hope Indefero will get to it before I do :-)10:39
wolfsprauljust try now10:39
wolfspraulwpwrak: try this: scp some_files www-data@downloads.qi-hardware.com:werner10:42
wolfspraulthey should show up under http://downloads.qi-hardware.com/people/werner10:43
kristianpaulthere is  recommende way to create project names, i noticed wpwrak used the prefix ben- wich is usefull to indentify ti is intende for the nanontoe10:46
wpwrakwolfspraul: works. thanks ! can i also delete files in some way ?10:46
wpwrak(except for overwriting)10:46
kristianpaulremote command?10:46
kristianpauli guess10:46
kristianpaulssh ww-data:@qi:werner rm -rf foo10:48
wolfspraulwpwrak: ssh should work. and just in case I added your pubkey to the root account as well.10:48
wpwrakkristianpaul: ah, that works. thanks :) getting to a shell was of course the first thing i tried, but when it didn't move, i thought it wasn't available. but now i see that it's just a little slow.10:49
wpwrakwolfspraul: you're making me worry about the security of my private key :)10:49
wpwrakactually, real per-user accounts would be better. less risk of mistakes.10:50
wpwrakwolfspraul: btw, did you find an answer to your question about breakout boards in my mail about the inrush current ?10:51
wolfspraulhmm :-10:52
wolfspraulI was thinking...10:52
wolfspraulthe answer seems to be at the end10:52
wolfspraulbut I am not entirely sure10:52
wpwrak;-) there's basically not a lot you can do from the outside. except to be careful about not making things worse.10:52
wolfspraulin your experiments you had the LCM removed. will it help if it's on?10:53
wolfspraulwhat does this mean for ben-wpan? is it doable over sdio?10:53
wpwraki think it should help a little. there's a lot of capacitors on there10:53
wolfspraulwhat does it mean for the breakout board? should we add some inductors there?10:54
wpwraki think ben-wpan should be fine. i'll just "precharge" the caps. the ohmic resistance of the chip is very high when it comes out of reset, so it doesn't discharge the caps10:54
wolfspraulxiangfu: remember we wondered why your 09-06 rootfs was smaller than mirko's 08-26? I diffed it and it seems to be mostly Qt related. your image is missing many Qt things compared to 08-26.10:56
kristianpaulwpwrak: do you mind if i use ben-gps for the project i'm working on?10:56
wpwrakfor the breakout board, it depend on how much the caps on the lcm help. if they are sufficient to reduce the drop to safe levels, then the only thing to worry about in breakout boards would be no to add capacitace - or put anything of that sort behind a bead10:56
wolfspraulif you want to I email the diff to you10:56
wpwrakkristianpaul: not at all. i don't own the ben-* namespace anyway :)10:57
xiangfuwolfspraul: yes. I also found that.10:57
wpwrak(inrush) if the lcm isn't enough to prevent disaster with discharged caps, you also need to worry about the resistance between VDD and GND.10:58
wpwrakof course a voltage drop of ~ 1V is a lot. well beyond all specifications. so at least in theory the lcm won't be able to help. in practice, it might, though. also it may also depend on what the machine is doing at the time a board gets powered up.10:59
wpwrak(won't be able to help) because it can, best case, only about double the capacitance on the "good" side. so you would still get too deep a drop.11:01
xiangfuwolfspraul: I am try to debug the uClibc 0.9.32. first I start with objdump dgclock. the compare the 0.9.32 and 0.9.30 result.11:01
wolfspraulalso try strace maybe?11:02
Action: wpwrak grumbles in the general direction of those "reduced" tools and environments11:05
wpwrakwell, uclibc is actually the least of my worries. busybox and dropbear are a different story, though.11:05
wolfspraulxiangfu: also I think in openwrt, you can turn on debug symbols globally. of course need to rebuild everything.11:07
wolfspraulmaybe cut it down to just dgclock and dependencies first, and use the buildhost if it helps11:08
xiangfuhmm... ok. but first I will start with strace and objdump :)11:14
wolfspraulkristianpaul: building the config.full_system image took about 9h on the server11:26
wolfspraulI don't think the server is memory bound right now, maybe disk or CPU. hard to say. could try to turn off the raid1, but I think for now it's good enough. server works :-)11:28
wolfspraulkristianpaul: actually I have an easy idea. the /home partition should be ext2 not ext3. next time you have nothing running let me know then I can quickly downgrade that.11:38
kristianpaulwolfspraul: do it now11:41
kristianpauli can wait for your is better now that theare few people11:41
kristianpauli'm out , take your time and let me now11:41
wolfspraulnow? he, OK. one sec.11:42
wolfspraulkristianpaul: maybe i can tech Linux software raid to favor performance over safety, instead of just turning it off11:47
wolfspraulwill check that tomorrow, maybe a setting somewhere...11:47
wolfspraulwe can still squeeze out some performance I'm sure11:47
kristianpaulsure no hury11:47
wolfspraulalso I can try to upgrade the memory and mount /tmp in ram11:47
kristianpaulwolfspraul: linux raid (faik-raiid) is not good in perfonrmance indeed11:48
wolfspraulkristianpaul: I'm done /home is ext2 now11:48
wolfspraulmakes more sense, should be a bit faster11:48
qi-bot[commit] Bas Wijnen: trying to simplify things, not working yet http://qi-hw.com/p/iris/3a38ea212:10
wpwrakheh, they should make that sound system outdoors-proof. then that would be something to put on my terrace :)12:33

kristoffertuxbrain2, you there?14:20
tuxbrainhello , kristoffer14:30
tuxbrainI'm in trip right now, but I solved the problem with greecee in the shop14:30
tuxbraintry again please and accept my apologizes14:31
kristofferroger will do14:31
tuxbrainurandom__: I have read you were able to run Supertux! and asking for interest in the wiki forum sorry I miss that, yes I will love to have it in jlime and Openwrt repos :)14:33
tuxbrainok guys must leave, anything until saturday better by email14:34
tuxbraindon't believe this tuxbrain2 :) is just a ghost14:34
tuxbrainc u (all)14:34
wpwraktuxbrain2: package is on its way15:04
wpwrakgrrr. i misunderstood how the transceiver's spi interface works. can't share miso and mosi after all :-( on the occasions where i saw it work, the signal shapes were quite horrible. ah well, back to the drawing board.15:23
emebtrying to tri-state them?15:28
wpwrakemeb: well, i thought that the chip would tristate MISO when it's not sending useful data. but i misread that paragraph and it only tristates it when nSS is inactive. so it's normal SPI after all.16:13
qi-bot[commit] Werner Almesberger: Found out that we can't share MISO and MOSI after all. Redesigned the atusd http://qi-hw.com/p/ben-wpan/3533e0417:04
GNUtoo|laptopI bought a GNU/Linux Magazine France today17:08
GNUtoo|laptopand there was an article on milkymist17:08
GNUtoo|laptoproughly they told that GNU stuff like gcc is kind of complicated to port17:08
GNUtoo|laptopto something like latice3217:09
GNUtoo|laptopI bet they plan to change that, for instance with the new license exception of GCC17:13
GNUtoo|laptopbut I wonder how much time it will take17:13
wpwrakkristian1aul: btw, how did things go with the new acid ?19:01
kristian1aulwpwrak: dint try yet19:02
kristian1auli need a thin PCB19:02
kristian1aulcurrent will not fit on the slot19:02
kristian1aulwpwrak: your PCB is thin by default or you did some work before?19:08
kristian1aulwork on it make i thinner19:08
kristian1aulohh my nick19:12
kristianpauldamm i almost lost my irssi config19:22
kristianpaulbut i'm bak :)19:22
wpwrakmine is 0.8 mm by design19:22
wpwrakwell, 0.79 mm :) http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=PC45-ND19:24
kristianpaulahh cute 0.8 :)19:26
kristianpauli need source that here19:26
kristianpaulah if sparkfun sell it i can buy it !19:27
kristianpaullets see19:27
wpwraknah, it's actually this one: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=PC44-ND19:28
wpwrak(same properties, but smaller)19:28
kristianpauli wonder why digikey dont ship in first class mail USPS and i wonder is asking for it will change something my bad feelins about a NOT Sr we DONT ...19:33
kristianpaulwpwrak: 1.2 will fit??19:39
wpwraknaw, too thick. the real card is something like 0.7 mm inside the holder, so we're already pushing tolerances19:45
wpwrakand you also want some decent board material. nothing that falls apart inside too quickly :)19:46
kristianpaulbtw hos this plastics PCB is made, i mean the routes19:47
kristianpaulilove my uSD to SD adapter19:48
kristianpaullooks so nice19:48
wpwrakhmm, dunno where i have my adapters. maybe they made some fpc and glued it inside19:54
wpwrakhmm. 21 o'clock and i'm getting hungry. seems that the monster steak i had ~23 hours ago is running out ...19:59
kristianpaulxiangfu: me computer still building all :)22:24
xiangfukristianpaul: :)22:24
qi-bot[commit] Xiangfu Liu: add nanomap icon http://qi-hw.com/p/openwrt-xburst/1f4c01822:38
GNUtoo|laptophi kristianpaul22:46
GNUtoo|laptopI bought a GNU/Linux Magazine France today, there was again an article on milkymist22:47
kristianpaullekernel posted on the Mail list22:47
GNUtoo|laptoproughly it's saying that GNU/Linux port is ultra-buggy and that they need some help22:47
kristianpaulof course i cant read that preview...22:47
kristianpaulbut tell more !22:48
GNUtoo|laptopand the reason is because you have to dig in undocumented GNU stuff22:48
kristianpaulas i said i cant read that (fuess nobody does)22:48
GNUtoo|laptopI'm summing up22:48
GNUtoo|laptopin my opinion(not from the article) : this is an heritage of "we don't want proprietary gcc plugins" thing22:49
GNUtoo|laptopfor gcc22:49
kristianpaulpropietary in wich sense?22:49
kristianpaulbecause lattice something?22:49
GNUtoo|laptopno, I explained badly22:49
GNUtoo|laptopI'll restart22:49
GNUtoo|laptopthe port is ultra-buggy22:50
GNUtoo|laptopyou get until that point right22:50
GNUtoo|laptopnow the reason is because GNU srtuff like gcc is kind of complicated22:50
GNUtoo|laptopthere is not only GNU22:50
GNUtoo|laptopbut linux too22:50
GNUtoo|laptopthe binary loader is kind of strange22:50
GNUtoo|laptopbinary loader means22:51
GNUtoo|laptopsomething capable of loading and running elf programs for instance22:51
GNUtoo|laptopthey also advertized something like FreeRTEMS or a similar executive environment22:52
GNUtoo|laptopor FreeRTOS22:52
GNUtoo|laptopI don't remember22:52
GNUtoo|laptopM stands for what now?22:53
GNUtoo|laptopbefore it was missile22:53
kristianpaulfocused on non.mm system22:53
kristianpauldont know about M  :/22:53
GNUtoo|laptopI'll wikipedia it22:53
GNUtoo|laptopI always forgett that22:54
GNUtoo|laptopand always remember the missile22:54
GNUtoo|laptopbecause I always said that the military were intelligent and saw that the secret thing was not the operating system22:54
GNUtoo|laptopbut the program running on top of it22:54
GNUtoo|laptopbut despite of this22:55
GNUtoo|laptopI heard that company using embedded stuff for writing custom applicaitons tend to think the contrary22:56
kristianpaulGNUtoo|laptop: so linux is the problem ,not gcc (including sompeple called "autocrap")22:57
GNUtoo|laptopit seem that everything is the problem22:58
GNUtoo|laptopgcc,linux,autotools etc...22:58
kristianpaulbut even lattive claim to use linux and encorgae people do it22:59
GNUtoo|laptoppossible, but after the status isn't great, if it could be fixed it would be great22:59
GNUtoo|laptopbut I'm not that deep into low level22:59
GNUtoo|laptopand I have no time for that22:59
Action: GNUtoo|laptop which he had more than 24 hours a day23:00
kristianpaulimage a 48 hourse dat, problem solved !23:00
kristianpaulGNUtoo|laptop: but you have idean where to dig to fing the missing clue in all of this gcc issues...?23:01
GNUtoo|laptopsleep depravation would be an issue then23:01
kristianpaulcause RTEMS uses gcc anyway23:01
GNUtoo|laptopah ok23:01
GNUtoo|laptopbut maybe not all its features23:02
GNUtoo|laptopfor instance try to build a linux kernel without gcc....23:02
kristianpaulwith llvm? :P23:02
GNUtoo|laptopthe linux kernel relies heavily on some gcc features23:02
GNUtoo|laptopllvm can use gcc23:02
kristianpaulah i see23:02
kristianpauli just wonder23:02
kristianpaulif gxx relies in x86 processor features ;)23:03
GNUtoo|laptopI don't think so23:03
kristianpauland why it end so sloww on mips systems?23:03
GNUtoo|laptopall versions works on x8623:03
GNUtoo|laptopnot true for the rest23:03
GNUtoo|laptopyou have to find the right combinaison of glibc,gcc,binutils etc...23:03
kristianpaulor there are processor that gcc thta run better in non-x86_64 arhcs?23:03
GNUtoo|laptopadd patches etc...23:04
GNUtoo|laptopkristianpaul, maybe your issue is that your cpu is slow?23:04
kristianpaulbut is out the box for x86_64 ?23:04
GNUtoo|laptopI think so23:04
kristianpaulahh thast it !23:04
GNUtoo|laptopx86 and x86_6423:04
GNUtoo|laptopyou've got a lemote?23:04
kristianpaulyes i do23:05
GNUtoo|laptopohh they have some newer models23:06
kristianpauland processors23:06
kristianpauli heard with x86 support or soemthin...23:07
kristianpaulso i think my point will make sence23:07
kristianpaulso neither lattice32 or mipsel are bad, just there is lacking support to improve performance23:07
kristianpauli guess with some ASM instructions23:07
kristianpaul(wonders what is etc )23:08
GNUtoo|laptopnot sure23:08
GNUtoo|laptopI eared that compiling is rather a general purpose thing23:08
GNUtoo|laptopnot sure what can accelerate it23:09
kristianpauldjbclark: asked about that i loonsoonglist23:09
kristianpaullet me fidn the thread23:09
GNUtoo|laptopI don't know compilation enough23:10
GNUtoo|laptopfor instance I don't know if there is a high usage of locking23:10
kristianpaul /j #gcc ? and ask?23:11
GNUtoo|laptoplocking can be fast or slow depending on hardware instructions support23:11
GNUtoo|laptoplet's find the thread first23:11
wolfspraulkristianpaul: for the raid on buildhost, we need raid0 not raid123:51
