<xiangfu> wpwrak, there is no 'set_irq_chip_data' in v3.2.1 any more

<whitequark> hm
<whitequark> can anyone suggest a nice RTOS for 32-bit CPU with 8k of RAM?

<wpwrak> xiangfu: ah, the dirty hacks are coming back to haunt us ...
jluis has joined #qi-hardware
<larsc> wpwrak: nah, set_irq_chip_data is just called irq_set_chip_data now
<larsc> tlgx did a big namespace cleanup
<larsc> tglx
<wpwrak> oh, good. thanks !

<xiangfu> larsc, thanks that is why grep give nothing.
<whitequark> wpwrak: can you answer a few questions about laser cut cases?
<whitequark> or, generally, cnc-machined ones
<wpwrak> xiangfu: can you fix this with a patch in the owrt build ? or do you need a change from me "upstream" ? i'm not set up for doing anything with wpan at the moment, even the bens are buried under layers of milkymists and midi devices, so it would be a bit inconvenient for me
<qi-bot> [commit] Xiangfu: xburst: nanonote: fix atusb compile error (master) http://qi-hw.com/p/openwrt-xburst/a4f9460
<wpwrak> whitequark: for laser-cutting, you may want roh. for milling, i may be able to help
<wpwrak> ah, that commit answered it ;-)
<xiangfu> wpwrak, yes. sure. buildhost is busy on compile. :)
<wpwrak> great, thanks !
<whitequark> wpwrak: well, my questions aren't specific for laser cutting
* wpwrak wonders if anything else is coming :)
<qi-bot> [commit] Xiangfu: cgminer: add include miner.php for web access cgminer (master) http://qi-hw.com/p/openwrt-packages/b9fad49
<larsc> wpwrak: I have a few questions regarding missile guidance and though you might know something about it ;)
* whitequark has been battling with CAD
<whitequark> e.g. I have this kind of connection
<whitequark> and I know that precision of the machine is X mm and the width of cut is Y mm
<whitequark> how much margin should I leave for the machine for the details to be connectable yet not too loose?
<wpwrak> larsc: fire away ! ;-) and always remember the quantity-vs-quality formula: #missiles = (deviation/blast_radius)^2
<whitequark> larsc: what country do you dislike so much?
<wpwrak> whitequark: hmm, i usually leave 0.05-0.1 mm between mating parts. but that also depends on the cutting process
<whitequark> hm, 0.1mm is the precision of cutting process afaik (well, it depends on the fab and I still don't know what one would I use...)
<wpwrak> i.e., you may have to make adjustments when going from (ideal) design to the toolpath
<wpwrak> would be be a problem if you had to sand off some plastic (at the interconnecting parts) ?
<whitequark> no, it's an one-time, one-part project
<wpwrak> then you could even leave no gap
<whitequark> sandpaper wins as usual. nice.
<wpwrak> it's easy to create a gap by sanding off things. much harder to close one because they're loose. (well, there's always silicone :)
<whitequark> oh, silicone is nice. it won't even damage the look (mostly)
<whitequark> ok. what about screws?
<wpwrak> yes, how will you keep things in place ? :)
<whitequark> the image only shows a part of the case
<whitequark> it's an M1 case clone. well, it wasn't supposed to be, but turns out that I just followed the easiest path and now I have an M1 case clone
<wpwrak> ;-)
<whitequark> ah I know. I'll ditch rounded corners and make them 45° cut.
<whitequark> then it won't be a clone.
<whitequark> also: more BSG-ish look.
<wpwrak> good. then roh won't sue you ;-)
<whitequark> did he patented the case? :D
<wpwrak> roh: see, you didn't have to hire all those laywers from apple vs. samsung after all
<whitequark> the funniest thing about apple vs. samsung is that they still use "some" samsung's services
<whitequark> for example, CPUs in latest iphone come from samsung
<whitequark> which leads me to the conclusion that it's just marketing
<xiangfu> what is the the back ground video in those videos: http://www.youtube.com/playlist?list=PL6E991D77D948B785&feature=plcp. seems not Milkymist One.
<wpwrak> oh, i'm sure samsung will comply with all the contracts they've made. in apple's place, i'd worry a lot more about what happens when these contracts end ...
<whitequark> ah. sure, contracts. companies are just like children having a grudge one against another, but the former, unlike the latter, have contracts.
<larsc> well, samsung != samsung. the samsung thats manufacturing the A5 is probably not the samsung that builds the smartphones
<wolfspraul> yes, not the same
<wolfspraul> those are all large business units that are managed independently, except for belonging to the same parent group
<wolfspraul> 'large' meaning each of those units has thousands of employees
jluis has joined #qi-hardware
<whitequark> yes
<whitequark> but I assume that lawyers don't care because parent company is the same
<whitequark> i.e. they share the responsibilites
<wolfspraul> lawyers care most that they can send bills for every working hour and every page of written text somewhere
<wolfspraul> if that's the case, they will start writing :-)
<wolfspraul> and I mean this in a respectful way of course, the legal system is very important imho
<wolfspraul> if you see a lawyer doing something you think is 'bad', you better look for who is paying and instructing the lawyer

<larsc> just for the record: for the irq namespace cleanup issue there is a coccinelle script which does a automatic conversion of old code. https://tglx.de/~tglx/genirq-namespace.cocci

<kristianpaul> great !! Takuji Ebinuma uploaded the namuru-gpl code http://www.sensorcomm.co.jp/osqzss/fpga/namuru/Namuru_GPL.zip !!
<kristianpaul> as it is gpl :-)
<kristianpaul> and it came with its own documentation as well http://www.dynamics.co.nz/media/DOCUMENTS/SOFTWARE_RELATED/Namuru-GPL-port-06.pdf
<kristianpaul> it was forked from osgps btw
<kristianpaul> morning too ;)
<kristianpaul> why this is great??
<kristianpaul> well osgps uses gp2021 registers
<kristianpaul> that some how are like namuru one, as it is a clone from above
<kristianpaul> but small details.. as always came up, so this port is a must try first on milkymist than the osgps
<kristianpaul> s/try/port
<qi-bot> kristianpaul meant: "but small details.. as always came up, so this port is a must port first on milkymist than the osgps"
<kristianpaul> ok, read you later :)
