Palisorry, not now, and probably not this week...00:01
Palimy notebook with maemo env is repairing...00:01
merlin1991ah damn00:02
merlin1991do you have the scripts around though?00:02

PaliI'm on n90000:03
merlin1991ah cool, I'll find them00:03
Paliand here I do not have any scripts00:03

DocScrutinizer05freemangordon: well, I don't know for sure who's those GTA04 kernel hackers, but I guess you can for sure get help of them01:07
DocScrutinizer05[2013-10-01 22:39:51] <Pali> nokia devs told me that n900 hw does not have needed hw  -----  seems android nevertheless implemented a working(?) driver for it?01:08
DocScrutinizer05also schematics clearly quote "ECI" and I can't see any significant bit of hw missing to *theoretically* implement that simple almost one-wire identical protocol01:10
DocScrutinizer05after all ECI is simple half-duplex serial via one wire, with pretty slow clock rate. You can even bitbang that stuff01:11
DocScrutinizer05and in N900 we not only got a direct GPIO/AD pin wired to mic contact of AV, we even got a hw schmidt trigger (ara level threshold) that is wired to another GPIO and probably even can trigger IRQ01:12
DocScrutinizer05so we have one open drain output to pull the line low, and a dedicated voltage level detector plus GPIO-input to read data from line01:13
DocScrutinizer05*AND* we have audio-in that as well serves for a pretty decent "scope digitizer" for later waveform processing and decoding of the serial pattern, just like e.g. magreader does01:15
DocScrutinizer05so we got THREE alternative ways to imlement data input, and one foolproof way to create data output (plus a less foolproof way by switching mic-bias off and on)01:16
DocScrutinizer05I don't think that Nokia info been to the point regarding ECI01:17
DocScrutinizer05(could somebody please point Pali to chanlog when he joins again? Thanks!)01:18

psycho_oreosTo the chanlog that you just wrote, about an hour later after pali left? done. :)01:30
DocScrutinizer05psycho_oreos: thanks!01:31
psycho_oreosDocScrutinizer05, no worries, thank you for contributing as well (along with many others) :)01:32

DocScrutinizer05[2013-10-02 00:29:49] <dos1> I think gta04-owner maillist may be useful for him01:36
DocScrutinizer05[2013-10-02 00:30:06] <dos1> kernel topics are often discussed there01:36
DocScrutinizer05[2013-10-02 00:31:06] <dos1> Nikolaus might also be the right person to ask, he seems to be taking some care of the kernel by himself01:36
freemangordonDocScrutinizer05: ok01:37
freemangordonI'll ask on the right irc channel once I've finished bisecting01:38

kerioDocScrutinizer05: 1317:30
DocScrutinizer05meh, it's just I'm rather sure the syntax for infobot isn't correct17:31
DocScrutinizer05~+help math17:33
infobot   Desc: math expresions can be evaluated. This uses Perl syntax.17:33
infobotExample: 1+117:33
infobot+ - add17:33
infobot- - subtract17:33
infobot* - multiply17:33
infobot/ - division17:33
infobot** - to the power17:33
infobotpi - pi17:33
infobot& - and17:33
infobot| = or17:33
infobot^ - xor17:33

DocScrutinizer05~sin(90)17:34
keriothere's no notation for knuth's up-arrow :(17:35
DocScrutinizer05~11!17:35
infobotwell, 11! is 39,916,80017:35
kerionot even close17:35

DocScrutinizer05(about DT)17:39
kerioDocScrutinizer05: add ackermann's function to infobot!17:40
DocScrutinizer05I can't17:41
DocScrutinizer05I have no access to the bot's "binary"17:41
keriowell, you only need like four values17:41
DocScrutinizer05I'm only "+o" and even have an access to restart the process on the server where it runs17:42
kerioA(4) is 2**2**2**65536-317:42

kerioperl sucks!17:43
keriothat's an integer!17:43
DocScrutinizer05orly? int16?17:44
DocScrutinizer05or int32?17:44
kerio*integer*17:44
kerioa bignum, if you prefer17:44
DocScrutinizer05so what? inf is bignum17:45
kerioinf is a float17:45
kerio~2**217:45
infobot417:45
keriomh17:45
RST38hfloating floating floating17:45
kerioi wonder if it's just a float internally17:45

DocScrutinizer05~0+pi17:46
infobot3.1415926517:46
kerioDocScrutinizer05: that's not conclusive - python3 gives a float when doing integer divisions17:46
keriounless you use the truncating one17:46
keriobut every other operation between ints returns an int17:47
*** wmarone has quit IRC17:47
DocScrutinizer05meh, seems like a niche topic17:47
kerio(and, obviously, ints have no upper limit)17:48
DocScrutinizer05orly?17:49
DocScrutinizer05~attack kerio17:49

freemangordon_DocScrutinizer05: mru is helpful as always been :)18:43
*** freemangordon_ is now known as freemangordon18:43
DocScrutinizer05mru?18:43
freemangordonDocScrutinizer05: remember my discussion on thumb2?18:43
DocScrutinizer05aaah18:44
freemangordon;)18:44
DocScrutinizer05k18:44
DocScrutinizer05I guess that's simply another (incompatible) concept of professionalism18:45
freemangordonno matter what it is, such a behaviour just sucks IMO18:46
DocScrutinizer05you know, there are guys in school who learn what interests them, and guys who study what is listed as being relevant for the test18:46
freemangordonyeah18:46
keriowho's mru?18:46
freemangordonkerio: an "ARM guru" I've been told18:47
keriothe one who said that thumb2 was impossible?18:47
freemangordon:nod:18:47
keriohe must be feeling kinda dumb for that18:47
freemangordonI doubt he gives a shit18:47
freemangordonabout that18:47
DocScrutinizer05"guru" as in "knows each ARM doc and manual by heart" - which in itself doesn't mean much yet18:47
freemangordoneven if we consider he knows18:48
DocScrutinizer05actually I think he never said "impossible" - he always said "not working and not worth it"18:48
DocScrutinizer05well, our mileage may vary ;-)18:49
freemangordonCBA to look if I keep irc logs, but iirc the term was "impossible and doesn;t worth it"18:49
DocScrutinizer05*shrug*18:49
DocScrutinizer05we know whom to ask what18:50
freemangordonnevermind :)18:50
DocScrutinizer05IOW we know *him*18:50
DocScrutinizer05a source of information is always as good as your knowledge about the source's quality and properies18:50
*** wmarone has joined #maemo-ssu18:51
*** arcean_ has quit IRC18:51
freemangordonanyway, I am only about 3000 revs to find which commit breaks SSI :D18:51
DocScrutinizer05:-D18:52
keriogit bisect?18:52
DocScrutinizer05yoh18:52
freemangordonyeah :(18:52
freemangordonit is a nightmare to do it on the kernel tree with patches on top18:53
DocScrutinizer05I bet it is18:53
freemangordonbut I hope I'll have a result by the end of the day18:53
DocScrutinizer05anyway funny enough that HSI been one of my majort problem issues in ST-E18:53
DocScrutinizer05-t18:53
DocScrutinizer05but our problems been with OMAP4 and lost IRQs18:54
freemangordonthe same problem here ;)18:54
DocScrutinizer05and HSI protocol specs don't really like to lose IRQs18:54
freemangordonI see no IRQs from SSI18:55
DocScrutinizer05well, we only *sometimes* lost one18:55
DocScrutinizer05culprit been a SiErr in IRQ handler18:55
freemangordonoh, I am in a better position, obviously :)18:55
DocScrutinizer05IP18:55
DocScrutinizer05sometimes the OMAP4 lost a "wake" IRQ when APR been busy in e.g. GFX core, or completely asleep18:56
DocScrutinizer05SiErr :-/18:56
freemangordonanyworkaround? disable sleep?18:57
DocScrutinizer05APE*18:57
DocScrutinizer05well, disable sleep works but defeats all puposes of embedded18:57
DocScrutinizer05we had to break the HSI prot specs and repeat our message from modem to APE18:57
freemangordonoh18:58
DocScrutinizer05indeed18:58
DocScrutinizer05and everybody always blamed the modem :-S18:58
DocScrutinizer05"no, look here, this are our logs and here we try to talk to blaze AP but it doesn't answer"18:59
DocScrutinizer05>:-(18:59
DocScrutinizer05TI: "WONTFIX in OMAP4"19:00
freemangordon"Bisecting: 2054 revisions left to test after this"19:05
DocScrutinizer05and you can replace "blaze" by ~5 other major companies' devices19:05
DocScrutinizer05real fun19:05
freemangordonwell, this is about 12 more tries19:06
DocScrutinizer05particularly since aour customers don't talk to each other, and your help desk neither tlaks to another segment of same helpdesk19:06
freemangordon1119:06
DocScrutinizer05your*19:06
*** arcean has joined #maemo-ssu19:06
DocScrutinizer05so you have 5 customers that blame your modem to not behave and all 5 have same TI chip which is actually the culprit19:07
DocScrutinizer05really I adore omap419:09
