| 01:29:38 | Klarion | Can someone help me? I want to be able to listen to sounds like in SineGen(which generates sounds on different frequencies) on my Rockbox so I can equalize my headphones properly. How do I get these sounds? Is this even possible? Can I download/generate them somehow. It can be for example 1k, 2k, 3k... up to 20k. |

| 01:37:30 | dfkt_ | Klarion, you can't generate tones in rockbox, but you can easily do it in eg. audacity |
| 01:38:17 | Klarion | ok, I'm in audacity now, can you pls tell me what do I put in amplitude setting? Default is 0.8. Is that OK? |
| 01:38:43 | dfkt_ | as long as it doesn't distort anything is fine |
| 01:39:04 | Klarion | ok |
| 01:39:22 | Klarion | waveform should be sine, right? |
| 01:40:17 | dfkt_ | maybe best you generate a sine-sweep from 20hz to 20khz, so you get a rough estimate where the peaks and valleys of your phone are |
| 01:40:30 | | Join Misanthropos [0] (~Misanthro@frnk-4d012ed8.pool.mediaWays.net) |
| 01:41:03 | Klarion | that's what I'm planning to do. I have to generate frequencies one-by-one. 50hz, 500hz, 1k etc. ? |
| 01:41:52 | dfkt_ | hmm, i guess audacity can't generate sweeps |
| 01:42:09 | dfkt_ | just google for sine sweep, and you should get some results |
| 01:42:18 | dfkt_ | it's one test tone that spans the whole audible spectrum |
| 01:42:57 | Klarion | I think I will do it like this first because I already practiced it on SineGen app. on my PC |
| 01:43:16 | Klarion | can you just tell me this: I have an option here in audacity when I want to generate a tone, it says, pick one: sine, square, sawtooth? Which do I pick? |
| 01:43:36 | dfkt_ | sine. it's just one frequency at once, with no overtones |
| 01:43:41 | Klarion | ok |
| 01:44:06 | dfkt_ | but personally, i just listen to music in fb2k with a vst eq plugin, and tweak my phones to my liking there |
| 01:44:17 | dfkt_ | then i take these settings and use them im rockbox |
| 01:44:28 | dfkt_ | much easier than trial & error with the rockbox eq itself |
| 01:44:57 | Klarion | yeah, but I figured that my PC might have a different frequency graph then my MP3 player |
| 01:44:59 | dfkt_ | and test tones never gave me really enjoyable results |
| 01:45:17 | Klarion | if you understand what I mean... |
| 01:46:00 | Klarion | so some tones might be different on PC than on player |
| 01:46:01 | dfkt_ | the frequency response of average pc sound cards and of most mp3 players should be fairly flat with most phones, there shouldn't be any huge differences in frequency response |

| 01:47:32 | dfkt_ | and that's basically the only thing that matters for EQing |
| 01:47:40 | Klarion | my sound card has totally rolled off bass, and my player is very flat |
| 01:48:53 | Klarion | and I have dual BA headphones which again are a bit problematic on some devices |
| 01:49:45 | dfkt_ | yeah, that can be an issue on crappy outputs |
| 01:49:59 | dfkt_ | what rockboxed player are you using? |
| 01:50:05 | Klarion | fuze v2 |
| 01:50:34 | dfkt_ | good, that one's flat with any impedance and crossover |
| 01:50:54 | Klarion | yeah, the measurements are same as clip+ |
| 01:52:44 | dfkt_ | here's a sine sweep i made - http://www10.zippyshare.com/v/17786075/file.html |
| 01:53:11 | dfkt_ | might be a good place to start |
| 01:53:15 | Klarion | oh, thanks, where did you make it? |
| 01:53:21 | dfkt_ | wavelab |
| 01:53:47 | Klarion | do my tones also have to be in .wav or can they be in any lossless format? |

| 11:58:19 | kugel | did that include rdlock->wrlock promotion? |
| 11:58:44 | jhMikeS | I didn't see any great issue with writer recurse since only one writer can recurse anyway |
| 11:58:46 | kugel | I think you cannot do that atomically |
| 11:58:51 | kugel | (with pthreads) |
| 11:59:44 | jhMikeS | rdlock->wrlock promotion isn't done with what I did either, it's almost nonsense |
| 12:00 |
| 12:00:10 | kugel | godo |
| 12:00:27 | kugel | well, you do it the other way around so I figured I better ask |
| 12:00:49 | jhMikeS | there is a way to do it but basically the app has to by wrapping the read exit and write acquire in a mutex |
| 12:02:09 | jhMikeS | well, heck I'll just put a patch up with a simpler version that should work with current trunk |

| 12:05:54 | kugel | the rd->wr promotion doesn't simply work with a mutex, any waiting writer has to hold that mutex |

| 12:07:14 | | Join kuldeepdhaka [0] (~kuldeepdh@unaffiliated/kuldeepdhaka) |
| 12:07:37 | jhMikeS | well it goes like: lock mtx->release rd->acquire wr->unlock mtx then you're in the writer lock |
| 12:08:18 | kugel | yes, but what there are other writers waiting? |
| 12:09:32 | kugel | if they don't hold mtx then the operation isnt atomic. if they hold the mtx it'll deadlock |
| 12:09:40 | jhMikeS | why? |
| 12:09:53 | jhMikeS | the mutex is only around the switchover code |
| 12:10:40 | kugel | you need to prevent other writers from getting the wrlock between the rd->wr promotion |
| 12:11:13 | kugel | how do you do that? if they hold the mutex as you suggest then the system deadlocks once the reader tries to lock it |
| 12:11:32 | jhMikeS | others wanting write have to get mtx, get write acces and realease the mtx |
| 12:11:48 | jhMikeS | reader doesn't lock it |
| 12:12:00 | kugel | reader locks it before "release rd" |
| 12:12:13 | jhMikeS | yep |
| 12:13:35 | kugel | if there is another writer (who waits for all readers to release), who has the mutex, it'll lock up because the reader will block on the wanna-be-writer to release the mutex and the wanna-be-writer blocks on the reader to release the rdlock |
| 12:16:19 | jhMikeS | only the reader that wants to write would block there |
| 12:16:37 | jhMikeS | anyone wanting writer would also wait for the mtx |
| 12:17:12 | kugel | the reader that wants to write would block? |
| 12:18:20 | kugel | how's that atomic then? |
| 12:19:00 | kugel | plus, "wanting writer would also wait for the mtx" == deadlock when the reader attempts to lock the same mutex |

| 12:44:28 | kugel | that is, don't support rw->wr lock promotion in the api |
| 12:45:25 | kugel | that's why I asked if you're planning on that |
| 12:45:31 | jhMikeS | I'll try...there must be a way |
| 12:45:38 | | Quit copper (Quit: ZNC - http://znc.in) |
| 12:46:32 | kugel | jhMikeS: I'm not sure it's even possible. See http://bitflipgames.com/2011/05/20/multithreaded-programming-part-2-5-mrsw-lock-code/ |
| 12:47:01 | | Join copper [0] (~copper@unaffiliated/copper) |
| 12:47:05 | jhMikeS | no, but I would like to correct that issue with the whole thing since I actually need it. |
| 12:47:58 | kugel | I suggest keeping it simple and don't do any lock promition |
| 12:48:19 | jhMikeS | I had an implementation like that then decided kernel native was better on target |
| 12:48:25 | kugel | instead having the client code deal with it explicitely |
| 12:48:47 | jhMikeS | that's what I wanted since it's not very common |

| 13:30:32 | pamaury | copper: I just received a micro sd extension card, so I should be able to sniff the traffic between rockbox and your microsd, I hope to be able to capture the "bug" on wire |
| 13:31:30 | [Saint] | nice. |
| 13:31:32 | Zagor | moo_: fixed |
| 13:32:15 | [Saint] | r105 - 13 Nov 2011 |
| 13:32:16 | [Saint] | heh |
| 13:32:37 | Zagor | yeah. "This document is historical and mostly out of date!" |
| 13:33:14 | copper | pamaury: a micro sd "extension" card? |
| 13:33:16 | copper | what's that? |
| 13:33:39 | pamaury | copper: this https://www.sparkfun.com/products/9419 |
| 13:33:43 | [Saint] | presumably for his fancy logic analyzer. |
| 13:33:54 | copper | ooh, nice |
| 13:34:36 | copper | I'll be very interested in what you'll be able to find out |
| 13:35:17 | copper | I wanna know if it's just a Rockbox bug or if those cards are indeed not to be trusted |
| 13:35:53 | copper | Rockbox bug or incomplete implementation |
| 13:35:58 | [Saint] | I have seen similar breakout PCBs that offer uSD RAID. |
| 13:36:06 | [Saint] | Now, why you'd want that...who knows. |
| 13:36:07 | copper | vs. "the card's firmware is screwy" |
| 13:36:09 | [Saint] | But they exist. |
| 13:36:17 | moo_ | [Saint]: where could I see some docs specifically for the ipod classic? most of the device-related pages don't have it listed |
| 13:36:33 | copper | moo_: use the iPod Video manual |
| 13:36:40 | copper | http://download.rockbox.org/daily/manual/rockbox-ipodvideo/rockbox-build.html |
| 13:36:43 | [Saint] | moo_: that's likely due to it being an unstable target. |
| 13:36:44 | moo_ | ok, thanks |
| 13:37:15 | [Saint] | But, copper is right - there's nothing in that manual that will be incorrect. |
| 13:37:19 | [Saint] | Only missing features. |
| 13:37:27 | moo_ | does any of you guys have it running? |
| 13:37:37 | [Saint] | No FM, recording, and various other trivial things. |
| 13:37:46 | [Saint] | I do. |
| 13:37:49 | [Saint] | copper does. |
| 13:37:52 | moo_ | I can live without those |
| 13:37:55 | moo_ | :) |
| 13:38:05 | * | copper does |
| 13:38:55 | moo_ | is there anything that can go wrong if I try the automated installer? |
| 13:38:56 | [Saint] | The caveats are: No specific maintainer anymore, and no official installation method. |
| 13:39:07 | copper | there is none |
| 13:39:08 | [Saint] | There is no automated installer. |
| 13:39:12 | copper | not for emcore anyway |
| 13:39:21 | [Saint] | Installation for this target is completely unsupported bu Rockbox. |
| 13:39:24 | copper | once emcore is installed, you can use the Rockbox Utility |
| 13:39:26 | moo_ | ok, I'll just follow the docs |

| 13:39:38 | copper | http://www.freemyipod.org/wiki/EmCORE_Installation/iPodClassic |
| 13:40:36 | copper | moo_: I don't remember for sure, but installing emcore might reformat your iPod's HDD and wipe out all your data on it, so make sure that you have a backup of that data |
| 13:41:03 | [Saint] | If it's going to, it will warn you clearly. |
| 13:41:15 | moo_ | I have it, no worries |
| 13:41:29 | [Saint] | ANother thing to note is - no dual boot. |
| 13:41:32 | moo_ | it will just be annoying if I have to copy it once again... |
| 13:41:41 | [Saint] | you can kiss the original firmware and itunes goodbye. |
| 13:41:57 | moo_ | yes, no problem, I kind of hate it anyway |
| 13:42:00 | copper | it's well worth it though |
| 13:42:04 | moo_ | it's a PITA on Linux |
| 13:42:24 | copper | ah, you're running Linux, that will make installing emcore easier |
| 13:42:28 | [Saint] | iTunes on Linux - why...dear God why... |
| 13:42:51 | [Saint] | Doesn't pretty much evrything use libgpod now? |
| 13:43:22 | [Saint] | (which will shortly be irrelevant, but hey) |
| 13:43:24 | moo_ | I used rhythmbox but it crashes all the time while copying stuff |
| 13:43:30 | [Saint] | Ah. |
| 13:44:40 | [Saint] | Head over to #freemyipod-support if you hit a snag with emCORE installation. |
| 13:45:04 | [Saint] | While not immediately obvious, freemyipod and Rockbox are separate entities. |

| 14:11:11 | moo_ | as a suggestion, there should be a way to rate them so people would download the best maintained and feature complete ones |
| 14:11:50 | moo_ | but having the choice feels awesome :) |
| 14:12:22 | [Saint] | A large percentage of those may or may not be hilariously broken. |

| 14:12:47 | moo_ | good to know, thanks |

| 14:17:38 | jhMikeS | kugel: oh I got the dumb sometimes but it really stupid simple...just forget promoting and put a mutex in the reader section :P |
| 14:18:44 | kugel | "forget promoting" sounds reasonable :p |
| 14:20:24 | moo_ | yay, rockbox is running, thanks guys |
| 14:20:29 | jhMikeS | well, it behaves the same as if it got promoted |
| 14:22:06 | copper | moo_: glad it went smoothly for you :) |
| 14:22:43 | moo_ | just had to follow the emcore wiki page, maybe it should be made more clear that's the way to install it on the classic |
| 14:23:56 | moo_ | I will try to use something like photorec to recover the data I had on it |
| 14:26:02 | jhMikeS | kugel: and the whole deal seems rather app dependent |

| 14:41:20 | moo_ | copper: can you tell how does rockbox battery life compare with the apple firmware's? |
| 14:42:11 | copper | 25-32 hours of continuous playback depending on the battery's age and codecs used |
| 14:42:40 | copper | actually I think codecs are mostly irrelevant on the Classic, wrt battery life |
| 14:44:02 | moo_ | apple claims it can do up to 36h, but 25-32 is not bad at all |
| 14:44:06 | copper | max I ever got was 32 hours, but lately it's more like 25 hours on my Classic, but I couldn't say if that's because my battery is getting old, or if it's something else |
| 14:44:58 | moo_ | I think it all depends how much they make use of the spinning disk drive |
| 14:45:36 | copper | even with ~440 kbps files I got 32 hours |
| 14:45:48 | copper | and with ~210 kbps files I got similar results |
| 14:47:10 | copper | if you want to make use of the large storage with high bitrate files, I'd say go for it and don't worry too much about battery life |
| 14:47:27 | moo_ | I won't :) |
| 14:48:07 | moo_ | it's actually my wife's device... I installed rockbox without her knowledge, hopefully I won't get killed :) |
| 14:48:38 | copper | lol |
| 14:48:51 | moo_ | the biggest reason was that I hated the sync experience on Linux |
| 14:49:41 | moo_ | so all the other rockbox features are just a nice bonus |

| 15:42:48 | copper | yeah, I'm always worried Apple will discontinue it |
| 15:43:37 | copper | though it's interesting they updated the firmware a year ago |
| 15:44:18 | [Saint] | Only to cope with an irrelevant (to us) HW modification, IIUC. |

| 16:05:08 | nrg | awesome :) |
| 16:08:14 | moo_ | how long does it take to reboot? it's stuck at the boot splashscreen |
| 16:14:11 | [Saint] | nrg: moo_: *never* use hard reset like a power down if you can avoid it (which is almost always unless the device is in a *panic*. |
| 16:14:21 | | Quit Strife89 (Ping timeout: 255 seconds) |
| 16:14:53 | [Saint] | nrg: long play is what you're looking for in such a situation. |
| 16:15:07 | nrg | oooo ok |
| 16:15:11 | [Saint] | try hard reset *only* if long play won;t do it (which is incredibly unlikely) |
| 16:15:18 | nrg | is that like a soft reset? |
| 16:15:26 | moo_ | good to know, thanks |
| 16:15:32 | [Saint] | Its actually physically powerig down. Safely. |
| 16:15:50 | nrg | ty |
| 16:15:50 | moo_ | I recovered it by deleting the rockbox database and configuration from the emcore tools |
| 16:15:55 | [Saint] | The hard reset method is the equivalent of pulling the plug. |
| 16:16:26 | nrg | the fun way |
| 16:16:37 | [Saint] | long power is governed by hardware, so it should work in most cases. |
| 16:16:55 | [Saint] | but there are times I have seen it completely unresponsive. |
| 16:17:03 | [Saint] | *long play, rather |
| 16:20:16 | [Saint] | nrg: out of curiosity - how on earth have you been shutting down? |
| 16:20:22 | [Saint] | Just waiting for idle timeout? |
| 16:20:55 | nrg | lol, well i havent used an ipod in years |
| 16:20:56 | [Saint] | The above makes it seem to me as though long play was a very recent discovery for you. |
| 16:21:04 | [Saint] | Ah, I see. |
| 16:21:19 | nrg | when i long hold power on my clip zip it tells me its shutting down |
| 16:21:24 | nrg | so i do that |
| 16:22:06 | [Saint] | unfortunately keymapping and hw-specific power functions don't translate between devices. |
| 16:22:10 | nrg | usually i have it on an hour idle timeout for shutting down too |
| 16:23:23 | nrg | yea i cant recall ever longplaying on a device |
| 16:23:36 | nrg | did that work for 4th gen ipods? |

| 19:33:00 | pamaury | also now that I have remove and reinserted the card I get no errors :-/ |
| 19:35:15 | pamaury | ok fun fact: if I reboot and run the test, I get faults, if I remove and reinserted, no errors, and if I reboot same cycle |
| 19:36:16 | copper | you remove the card while Rockbox is running? |
| 19:37:09 | pamaury | yes |
| 19:37:37 | pamaury | and if I remove it a second or third time, also no errors |
| 19:37:42 | copper | :-O |
| 19:38:19 | copper | I thought, doing that would make puppies cry, or something |
| 19:39:15 | pamaury | not if nothing is read/writing to it |
| 19:39:31 | pamaury | rockbox does do aggressive write caching so all writes are nearly immediate |
| 19:39:41 | pamaury | the FS will usually stay consistent |
| 19:40:56 | pamaury | also plugging USB seems to have an effect |
| 19:41:01 | pamaury | so it might be a power issue |
| 19:42:19 | copper | that's something I can picture |

| 20:11:56 | pamaury | copper: good news, I have a reliable way to reproduce it now |
| 20:12:09 | pamaury | it triggers within seconds |
| 20:13:59 | copper | hw? |
| 20:14:01 | copper | how? |
| 20:15:34 | pamaury | just random reads + retry, and disabling dircache |

| 22:54:20 | pamaury | copper: I just discovered something strange, all the failing read actually request for....0 sectors ! It's clearly a bug in my code but the question now is whether this is this bug which you triggered or another one |

| 23:18:59 | pamaury | wodz: my guess is the following, when called with count=0, it will actuall ask the card count-1 sectors in some occasion |
| 23:19:38 | pamaury | for microSD cards, this amount is probably invalid but not on microSDXC ? |
| 23:20:04 | pamaury | but still I agree it's strange |
| 23:20:38 | pamaury | on the other hand i'm not even sure this is the actual bug, and it must be quite rare for the upper layer to call storage read with size 0 |
| 23:20:41 | pamaury | (if possible) |
| 23:22:04 | wodz | actually calling with size 0 looks like a bug (although driver should handle this gracefully) |
