00:06:33n1shmm, there's a patch for x^y in the tracker but i doubt the poster tried it because he used pow() but didn't provide a pow function...
00:09:24*amiconn doesn't understand why calculator.c uses a separate variable for the exponent
00:13:21amiconnn1s: Well, the most important functions are obviously ln() and exp(). Once you have those, you can easily implement log(), 10^x, x^y etc

00:35:58saratogahmm i don't understand blackhawk's concerns about the headers he used to compile for the moto cell phones
00:36:21saratogathey appear to have been reverse engineered without access to any non-GPLed code, and are released under GPL license
00:37:13linuxstbWhere are blackhawk's concerns?

00:38:16saratogaalthough it might be a problem that the build tool needs a binrary lib file off the phone itself
00:38:35saratogaif its actually linked into the rockbox binary
00:38:53 Quit bluebrother ("Verlassend")
00:40:01linuxstbSo these phones are based on qt/embedded, which isn't open source?
00:40:10saratogaits GPLed
00:40:24saratogabut moto apparently licensed it under proprietary terms and made minor changes
00:41:31 Quit Synergy6 ("Adios")
00:42:19saratogathese changes were then reverse engineered to modify the qt GPL headers to work with the system libraries on the phone
00:42:26saratogaat least thats my understanding
00:43:32linuxstbAnd you're still interested in this target? ;)
00:44:11saratogasee http://lsb.blogdns.com/ezx-devkit
00:44:25saratogalinuxstb: well, it apparently works, so I'd like to get it merged into SVN
00:45:02saratogahow often does someone give us a patch that adds support for 5 or 6 new targets
00:45:08saratogaeven if its a mess
00:45:15saratogaanyway, got to run
00:45:20linuxstbIMO, if we can't distribute the build environment, it's not worth incorporating in SVN. But maybe that's just me...
00:45:34saratogawell the build tools are GPL, so we can do that
00:45:55linuxstbBut if it requires "illegal" header files, no-one can build it.
00:46:24saratogathe headers are legal, at least the author says they're reverse engineered and he licenses them under teh GPL
00:46:27toffe82n1s: for the calculator, you can test is the user font is ok in size, if not use the system font
00:46:35saratogai can't find anything about a leaked moto sdk, so I'm not sure what thats about
00:49:32n1stoffe82: yes, that's what I do

02:37:15bleakedalso, i'm sorry if this is documented (just spent 20 min looking on teh wiki) but what is the most painless way to update rockbox without losing my settings or it overwriting my themes/fonts/etc..

04:32:33saratogayou could probably modify the source code to write a log pretty easily
04:32:39scorcheyou also might want to check out the Gather Runtime Data option for the database
04:32:39tkoodaso I can't just play whatever I feel like at the time and have it log it? -I have to pre-emptively add the tracks to a playlist, play from that, and then remember which was the last one I played?
04:32:48tkoodaI'll checkout GRD
04:33:21tkoodais there any way to prompt the WPS screen for a Yes/No between tracks?
04:33:23scorcheas saratoga said, to implement such a logging would probably be pretty simple
04:33:39scorchewhy would we have that?...again, you could code something up
04:34:22tkoodaI'm going* to try. I'm asking if there's some pre-existing interface for promting the user or something that I would want to leverage (so as to get the code accepted upstream)
04:34:41saratogathats not going to be accepted
04:34:57scorchethere isnt any valid usecase for that option in normal use
04:35:07tkoodaa "prompt for delete after playing" option wouldn't be accepted?
04:35:25scorchei wouldnt think so
04:35:45scorchenot to say that you shouldnt try...if you do, at least there will be a patch
04:35:48tkoodaI play audio from rss feeds and want to indicate what ones I've played (so I can delete them next sync), or, even better, delete them right then
04:36:23tkoodais there another/suggested way to play audio from rss feeds (where you want to delete the audio after hearing it once)
04:36:26tkooda?
04:36:50saratogacontext menu and choosing delete
04:37:00scorchethis is embedded programming...everything we add has an impact on our finite resources so things need to be looked at to see if it is really worth adding
04:37:48tkoodascorche, is it feasable that an option would be accepted upstream, but disabled by default at compile time?
04:37:55scorcheit is 2 button presses away from deleting, so i do not think adding an option for an auto prompt would be justified
04:38:15tkoodaperhaps I'm just unfarmiliar with the delete interface. I'll try again now.
04:38:19scorchethat would unnecessarily add complexity to the code
04:38:43scorcheif you make a patch, you can just put it on the tracker...
04:38:44tkoodadebatable. (I believe the video player is more than I'd like on my device right now)
04:39:20scorchethen ifdef it out..
04:39:49scorchehowever the video player is a plugin....this does not add to the core (beyond API changes)

07:35:08midgeyjhMikeS: (for the logs) I think FS #8906 is SDL's fault
07:35:51midgeyi loaded up the sim under gdb in os x and linux to see why it froze on the mac
07:36:24midgeyit seemed to get stuck in switch_thread, specifically in the case SDL_MUTEX_TIMEDOUT
07:37:48midgeyon mac, gdb reports the sim enters the while loop on line 302 and never exits. it just pings back and forth between line 302 and 303
07:38:18midgeyon linux, gdb reports the sim does not enter the while loop and continues on to restore_irq() on line 306
07:38:41midgeyi'm going to try updating sdl to see if the problem goes away.
07:39:11midgeyright now i'm on 1.2.12 and i'm trying to upgrade to 1.2.13 (configure seems to be stuck...)

08:02:00MSIHi, I had a quick question about using Rockbox on my 30GB 5th Gen iPod Video. Where exactly would I place my music for it to be able to read the database? It seems to have messed up when I tried doing so via my itunes library.I ended up having to restore the ipod. Any help would be wonderful, thank you.

08:06:50brent113_has it ever worked with that version of firmware?
08:07:39MSII don't honestly know, as this is the first time I'm using it. The ipod firmware is v1.3 though
08:08:02brent113_did you use the rockbox util and it downloaded the firmware for you?
08:08:09MSIyes
08:08:22brent113_my friend just had a problem with that, the downloader downloads an old version
08:08:34brent113_you need to manually download the newer one
08:08:40MSIwell i just updated it to a new daily build
08:08:53MSISo I guess we will have to try that.
08:08:54brent113_oh, so what's the problem again?
08:09:51MSII don't know where or what folder to dump my music back into. I'm not fond of iTunes anyway so is there another way to add my music maybe something as simple as a folder called Music on root?
08:10:34brent113_1) don't use itunes, your ipod is now a usb device using a different database and 2) it doesn't matter what folder
08:10:53brent113_use winamp or something, it doesn't really matter, just not itunes
08:10:54MSIso I could just make a music folder and it would go fine
08:11:05brent113_you could dump it into root, a music folder, whatever
08:11:10MSIOk thanks
08:11:12brent113_i have mine in a folder named songs
08:11:21brent113_hopefully that helps, i have a sansa
08:11:27brent113_that's what i'm basing it on
08:11:44MSII'll dump like 3 songs on and test it
08:11:46MSI;)
08:11:55amiconnjhMikeS: Why do you need to fake IRAM on the beast at all?
08:11:58MSII'll get back to you in a minute to let you know if it works out fine
08:13:10midgeyjhMikeS: and if it's helpful, i've uploaded the gdb output from both sims (albeit with some differences in sdl, rockbox version etc)
08:13:15midgeyhttp://pastebin.ca/1004658
08:13:33midgeysdl 1.2.13 made no difference
08:13:45amiconnIt should be sufficient to make sure that config.h lines 423..453 define all I*_ATTR macros as empty

08:15:20jhMikeSamiconn: it's only 16K and works for the time being. I'll evaluate later.
08:15:40MSIas the audio is jumping, and vocals are chimpmunked
08:16:03amiconnjhMikeS: I know that you don't use it. I mean you shouldn't need to fake it, as config.h makes sure no C code will require it
08:16:17midgeyjhMikeS: those line numbers from earlier are in thread-sdl.c
08:16:28jhMikeSthere's some cases of iram used in asm code
08:17:08jhMikeSright now it's more of a concern to get it playing music since that could happen from the next few minutes to the next weeks depending if I figure out the correct setup
08:17:11amiconnHmm. In that case I'd rather ifdef the asm code.
08:17:34jhMikeSmidgey: I'll have a look
08:18:26amiconnThere are a few asm files where that's done, e.g. ata-as-arm.S

08:31:13midgeyso that change should have no effect on the problem?
08:32:21jhMikeSActually, yes, if I used SDL_SemWaitTimeout to implement sleep and timeout blocks...one moment
08:33:06midgeyyou did, according to thread_sdl.c

08:35:10Buschelgood morning
08:35:32*Buschel did a runtime test with disabled line out on his 5.5G
08:35:51Buschelseems to give about 15 minutes additional runtime
08:36:35Buschelthe line out is driving against 100kOhm from my yesterday's measurments on the dock connector
08:38:03BuschelI would like to add en-/disabling the line out to the accessory power on/off. anyone knows a use case where line out is needed without a accessory connected?
08:38:11amiconn15 minutes is just measuing uncertainty
08:38:25jhMikeSthere's an S/PDIF enable/disable so it makes sense to me to have an option
08:38:46Buschelamiconn: it's from the 90->10% runtime which is quite accurate over several measurements
08:39:44amiconn100kOhm means ~10uA at 1V eff - that's neglectible
08:40:00amiconnI wouldn't waste an option for that - we already have too many options
08:40:09Buschelamiconn: i don't know what the amplifiers suck though (only when enabled)
08:40:15 Join perplexity [0] (i=heh25057@dxb-as82214.alshamil.net.ae)
08:40:24jhMikeSwhat about transistor bias currents?
08:40:38amiconnThe s/pdif enable/disable is only present on iriver H1x0, and makes sense there, because the LED sucks several mA
08:40:52Buschelmy idea was to add en-/disabling to the already present accessory supply option
08:41:07amiconnThe archos recorder also has s/pdif, but electrical, and we keep it always enabled there
08:41:28Buschellike: accessory on -> power supply pin13 + enabling line out. accessory off -> power supply pin13 off + disabling line out
08:42:11Buschelno additional option, as users would need to set both then
08:43:19*amiconn thinks Buschel is overdoing things in his quest to save power
08:44:13amiconnI mean, rockbox exceeds OF battery runtime on quite a number of targets, without using such extreme measures as disabling line out for a few uA
08:44:14jhMikeSnearly 100% of the battery usage must be just from self-discharge :)
08:44:41 Join n1s [0] (n=nils@rockbox/developer/n1s)
08:46:08amiconnSo I think there's still something undiscovered on PP that allows to save a considerable amount of power
08:46:31*Buschel thinks even small steps add up to a significant result
08:46:51Buschelgerman: "Wer den Pfennig nicht ehrt, ist der Mark nicht wert." :)
08:47:04Buschelwould be Cent and Euro now, of course
08:47:34linuxstb_Buschel: But these are small steps that the Apple firmware doesn't do...
08:47:34amiconnWell, of course small steps add up, but then those small steps shouldn't reduce ease of use
08:47:48 Join homielowe [0] (n=eric_j_l@66.183.89.40)
08:48:28amiconnRight now line out is plug-and-go, and imho that's _the_ advantage of having a line out (over having to use the headphone output as line out, which means having to adjust volume, treble, bass etc to all-linear)
08:49:27Buschelyes, but when connected to the already present setting there is no additional user interaction needed at all
08:49:28jhMikeSBen Franklin: "A penny saved is a penny earned." :)
08:49:54amiconnBuschel: This accessory power option should go away of course
08:50:15amiconnAccessory should be powered automatically when detected
08:50:18linuxstb_Buschel: What do you mean? There are lots of simple adapters to access the line-out, which I wouldn't class as accessories.
08:50:58amiconnBtw, could it be that the OF runs the accessory power converter in eco mode for detection, and switches to normal mode when it detects an accessory?

08:52:24*jhMikeS would like a logic analyzer about now or should carefully go for the oscilloscope.
08:52:49Buschellinuxstb: that was one of my major questions. so, you say there _are_ accessories using line out which are not classed as such?
08:53:24*amiconn doesn't trust battery runtime changes of less than 5%, even if they're determined using the 90%->10% levels
08:53:34scorche|shBuschel: i use line out on as many devices as i can...i use it to connect to a much higher quality amp then connected to my headphones
08:53:50scorche|shit is the only way i listen, really
08:54:19Buschelamiconn: good point, but pin13 seems to drive against some kOhm within the iPod itself. ECO-mode would limit this to 5mA, the current now is ~1.5mA -- so below this limitation
08:55:31amiconnMaybe, if you're doing at least 10 runtime tests with a certain setting (preferably on 10 different devices of that target type), and then average the results.
08:55:54linuxstb_Buschel: I have a simple dock which provides line-out, USB and firewire sockets. I don't think I would class it as an accessory.
08:56:06linuxstb_I also have a "home-made" line-in/line-out cable.
08:57:56Buschelit is clear that the line out disabling in context of the accessory detec/setting makes no sense if there are such simple solutions availabe in the market
08:58:12Buschel*detect
08:58:25amiconnBuschel: Eco mode would at least make the converter itself consume less. If it's really some pull down resistor in the ipod itself, there must be another way to solve that (i.e. RE...)
