qi-bot[commit] Ayla: The conf file does not need to be saved on exit. (master) http://qi-hw.com/p/gmenu2x/9768a7400:36
Aylaguys00:39
Aylamind if I remove the help menu on gmenu2x?00:39
Aylait is useless, it shows controls for the GP2X port only00:39
wolfspraulps2chiper: good morning00:40
wolfspraulAyla: then remove sounds great!00:41
wolfspraulwrong information is worse than no information00:41
wolfspraulps2chiper: I read the huge backlog, well, skimmed it00:41
Aylaor maybe I can wrap that code into #define00:41
rohwolfspraul: ;)00:42
wolfspraullarsc: you work for ADI? congratulations - that sounds like an excellent company for you!00:43
wolfspraulif you find out about any super interesting new ADI chips, let us know. We can build some cool products with them :-)00:43
wolfspraulI'm trying to understand the business model and future of Blackfin and SHARC for a while, if you get behind those mysteries, please share. (of course without breaching any confidentiality, just to share qualifications on how/if/when to use them, where they are going)00:45
larscwolfspraul: i'll keep my eyes open00:58
larscand yes, i guess it a good place for me to work at. couldn't have said no.01:01
erikkugelhi all, quick inquiry, wondering if anyone knows who's the original author of this page: http://en.qi-hardware.com/wiki/Building_OpenWRT_on_Debian_601:12
erikkugelit's the Wiki page for building OpenWRT on Debian 601:13
erikkugelI'm asking because I'm curious how can the instructions be updated for following releases (they currently refer to the February build).01:14
erikkugelI'm trying to just change the release number when checking out with GIT, but attempting that for the August build failed (the build quit when building cryptography libraries, which were not part of the broken packages list). I'm trying now with May build, after also removing the now unnecessary ALSA-LIB patch, but I was curious if I'm missing something obvious.01:15
qi-bot[commit] Ayla: Dingoo port: The help menu now displays help for dingoo's controls. (master) http://qi-hw.com/p/gmenu2x/03a26a801:20
rohre02:27
whitequarkJust tried to disassemble DSDT on a recent hp laptop02:35
whitequarkthey've put a complete VT100 emulator and the setup utility inside.02:35
whitequarktogether, it is roughly 27000 lines long.02:35
whitequarkI just had to share this insanity with someone.02:36
wolfspraulwhat is DSDT?02:38
whitequarkthe main ACPI table with bytecode02:39
whitequarkthat is, it is a huge chunk of bytecode stored in BIOS and executed by OS kernel (or EFI, if there's no OS loaded yet)02:40
whitequarkoriginally, it was developed to power off the system gracefully or adjust the brightness of a laptop screen. Then, at some point, it turned to four-revision, 800-page-long specification with two appendixes.02:41
whitequarkI've discovered all of that while trying to determine why a software-induced brightness change on my laptop produced spurious keypresses02:42
rejonwpwrak, wolfspraul what do you think about this stuff http://keithp.com/blog/ is doing with rockets02:55
rejon?02:55
rejonwe should get them onto qi with their hardwrae02:55
rejonof course they are hobbyist, but we should find ways to collaborate02:55
wolfspraulyes sure of course03:01
wolfspraulthey are doing a quality job on licensing I think, really everything is open and GPL licensed etc.03:02
wolfspraulthey are technically ambitious03:02
wolfspraulthat's all I think about it right now :-)03:02
wolfspraulI have added the Altus Metrum RSS feed to the Qi planet already03:02
wolfspraulso that will give me or other Qi planet followers the chance to follow and learn about their progress over time, and find ways to collaborate/reuse03:03
wolfspraulthat's as much as I can do right now03:03
ps2chiperim back06:08
ps2chiperi needed to sleep06:08
Jade119hi06:48
wolfspraulps2chiper: what was the main question or point you wanted to make?06:53
wolfspraulI read through this huge backlog but the more and faster I read the less I understood :-)06:53
wolfspraulthere must be something exciting there though...06:53
ps2chiperi was just looking for someone to help me get ubuntu 10.0406:53
ps2chiperthen the guys started complaining about kernel lockin06:54
ps2chiperand i pointed out that all the soc vendors today have that problem06:54
wolfspraulah I see :-)07:11
ps2chiperdid i miss anything?07:37
wolfspraulno, I think I got it now. sorry I was confused by the many different arguments in that thread.07:38
wolfspraulthen it turns out the original question was about ubuntu 10.04 :-)07:38
ps2chipernobody could answer the question of a non eol soc that has open userspace for the gpu.07:40
wolfspraulthat's why we invest heavily in, and believe, and are in love with...07:40
ps2chiperhey wolfspraul, i dont know if you remember me. but we spoke a few years back over skype07:40
wolfspraulMilkymist :-)07:40
wolfspraulsorry I do not clearly remember, no07:40
ps2chiperxiangfu-liu told me all about milky mist07:41
wolfspraulI would love to make more products with it07:41
wolfspraulthe first one is just out, Milkymist One07:41
wolfspraula video synthesizer, which we will add more functionality to now07:41
ps2chiperwell i had some ideas of my own07:41
ps2chiperopenwrt powered clock radio07:41
ps2chiperand openwrt powered voip phone07:41
wolfspraullet's talk about the chips first07:41
wolfspraulhardware acceleration is tough07:41
ps2chiperralink07:41
ps2chiperif you dont want to talk, i need to ride my bicycle07:44
wolfspraulhow is that related :-)07:45
wolfspraulthat's funny07:45
wolfspraulride your bicycle07:45
wolfspraulthat's always preferable to talk I'd say07:45
wolfspraul:-)07:45
wolfspraullet's talk some products soon, it's good to hear back07:45
wolfspraulsince you are in shenzhen and work for factories etc. we probably share a lot of the same experiences07:45
wolfspraulI'm thinking about a lot of new things07:45
ps2chiperthat its getting late in the afternoon and i need to do some exercise, how is that funny?07:46
wolfspraulfrom Milkymist On expansion boards, to speakers/headphones, audio controllers, laser projectors, improved NanoNote, and so on07:46
wolfspraulall the way to the BuddhaMachine :-)07:46
ps2chiperour current goal with amlogic is to get xbmc with dvb support going on it for a dreambox killer07:46
ps2chiperyou should also hear my open cola idea07:47
wolfspraulany time, I'm reading the channel07:47
wolfspraulin my experience, the 'anything' killer will not kill 'anything', btw07:47
ps2chiperok, well to make the opencola idea short. we take a soda fountain and place it in colleges and use that machine to advertise oss related work. show college students how linux can earn more money than windows.07:48
ps2chiperyou should also do a karaoke projector07:50
ps2chiperpeople like to party 07:50
wolfspraulI'm thinking about speaker, laser projector07:50
wolfspraulbut it's just thinking07:51
ps2chiperwell from my point of view, you should build products normal people want to buy, and they can be foss and open source hardware too07:51
ps2chiperi should ride my bicycle now. ill be back in an hour07:52
wolfspraulride safely07:58
ps2chiperim back08:29
ps2chiperi got rained on08:29
valhallaps2chiper: is the opencola idea related to the opencola homebrewed cola recipe?09:08
Last message repeated 1 time(s).09:23
ps2chiperyes, how they used open source cola to promote open source software09:23
LunaVoraxHello everyone !09:24
ps2chiperhi09:25
qi-botThe build has FAILED, see log here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-09042011-0058/09:27
Jay7open source beer should give more promoution :)09:27
Jay7*promotion09:28
wpwrak"X killer" will usually be killed by another "X killer", for the brilliant idea of doing something that' s just like a successful product is amazingly contagious ;-)09:36
wpwrakJay7: (open source beer) not a good ideas. if you do this, then everybody needs to change their "like free speech, not like free beer" analogy09:38
ps2chiperok09:41
ps2chiperfree beer is expensive09:45
lekernelwhitequark, what's the point of the VT100 emulator?09:45
lekernelwhitequark, and since the setup utility is in the DSDT, I guess you can run it from linux?09:46
ps2chiperyo Ayla10:38
ps2chiperwhats new10:38
Aylahi10:43
ps2chiperwhats up10:43
Aylanothing new10:43
ps2chiperdid you get a chance to review the amlogic source code10:43
Aylait does not download at all10:46
Aylait can't find a single peer10:46
ps2chiperyou can also dowload it from openlinux.amlogic.com10:46
Aylaah ok10:49
ps2chiperwill you have time to look at it today?10:50
Aylanot today10:51
Aylawe want to release opendingux today10:52
Aylawhat do you want me to review anyway?10:52
ps2chiperto see if it can work with ubuntu 10.0410:52
Aylathe board?10:52
ps2chiperi can send a board after you review the source code10:53
lekernelwhy put more effort into making software work on yet another proprietary soc? help with the linux port on milkymist instead ...10:53
ps2chiperbecause all soc's with a gpu have this issue.10:54
Aylaso you're asking me to port ubuntu? ...10:55
lekernelwhat gpu functions do you need?10:55
ps2chiperone of my goals is to find a person to port ubuntu to the amlogic soc if possible.10:55
Aylaeh, you didn't tell me that last time10:55
ps2chiperyou left before i could10:56
Aylaok10:56
ps2chiperremember i told you i wanted to do profit sharing projects10:56
lekernelthat's a stupid goal, if you want to use some proprietary soc just take one that has a wide existing software support, like ti omap10:56
ps2chiperan ubuntu thin client is one of my ideas10:56
lekernelso you're not wasting time supporting some company's proprietary design10:57
Aylalekernel: that his company's10:57
Aylathat's his company*10:57
ps2chiperi support foss, but im noting going out of my way to make a statement. i rather build something that would make people happy.10:58
lekernelthis channel is about copyleft hardware, not about recruiting people to work on proprietary hardware10:58
ps2chiperi never said proprietary. but if you are buying a soc, its proprietary too. they wont give you the information to make your own soc.10:59
ps2chiperthe only one that does that is opensparc10:59
lekerneland leon3, and milkymist, and others11:01
ps2chiperso what ip core do those products use?11:01
lekernelthey are custom made11:02
ps2chiperis the ip licensed under an free software license?11:02
lekernelfor the RTL part that is - physical IP (e.g. standard cells, FPGA tools, ...) is still proprietary so far11:03
lekernelyes11:03
ps2chiperso if you want to go that far. you shouldnt use there products because you are not freely able to manufacture their soc's your self11:03
lekernelthat's the next step - and the RTL source is portable, so if we want to make that step, we can11:04
ps2chiperRTL real time linux, Im assuming?11:05
lekernelno, register transfer level11:05
lekernelverilog/vhdl sources11:05
lekerneland by the way milkymist has graphics acceleration ip, also freely licensed11:06
ps2chiperso its opengl es 1.1 ?11:06
lekernelit's not complete, but can be completed without fundamental problems11:06
lekerneljust the parts of it that I needed to run milkdrop :-)11:06
ps2chiperdo you mean open source divers to replace the proprietary drivers?11:07
lekernelno, I mean free software licensed Verilog sources that describe the "GPU"11:07
ps2chiperthanks for that, now who makes a cortex a9 soc with a open userspace for the gpu?11:09
lekerneli'd rather make a LM32 soc with a free GPU *HDL description, and for the software drivers X is something I won't touch, but I don't see issues for making the rest open source11:10
ps2chipermaking ic's is above me. so i will leave it a lone11:12
ps2chiperback you Ayla11:13
ps2chiperback to you Ayla11:13
lekernelthis is a hardware channel, so it should be about making IC's11:14
ps2chiperyour welcome to talk about it.11:14
mthdoes anyone know how I can remove a remote branch?15:10
mthpreferably without removing it locally15:11
mthin git15:11
icestorm_i think it was git push with ':branchname', but you have to be very sure about that15:12
mthyes, that works, thanks15:13
