02:49:32star_jasmineactually, it says too many open files, as the error, siting the name of the log file it wishes to open

12:55:33funmanhe told yesterday that he would be here 'tomorrow'
12:56:08jhMikeSamiconn: indeed. it shouldn't need much but it would be nice to have charging in SVN and it should be liveable for now. adjusting it should be simple. it really should have an event queue or it can miss important transitions to act accordingly.
12:57:22jhMikeSamiconn: what overall restructuring did you have in mind, if any?
12:58:18amiconnThe basic powermgmt loop needs to be reversed. Right now there is a "short wait" and a "long wait" function.
12:59:03amiconnThe loop should rather be always active and should call the "seconds-task" and the "minutes-task" at configured intervals
13:00
13:00:01amiconnThis is the only way to guarantee prompt reaction to events. I need this for suspend on 1st/2nd gen.
13:00:02jhMikeSamiconn: the S patch has 99% in the short wait function (so it is as you put it "reversed")
13:00:20amiconnThere should be no short wait or long wait functions
13:03:31amiconnThere should be functions for the various tasks, which get called from the main loop regularly, and which return immediately after doing their part of the job
13:07:01jhMikeSyes, that would flatten it out nicely. what about the NiCd code−− it has dependence on counting
13:08:25amiconnIt needs to be adjusted of course

16:22:16joetooWeird. I just looked in irc.netsplit.de to find out where #rockbox was, and it said there wasn't one.
16:26:55joetooI notice that rockbox has basic video decoding support, but I'm interested in xvid. I see that the V.2 sansa e200's have divx, which makes me wonder if my V.1 has enough cycles to decode xvid. Looks like my OEM firmware only supports mjpeg in .mov, which obviously uses a lot of space.
16:27:34 Quit lasser (Remote closed the connection)
16:27:49markunjoetoo: interested as in "I want to work on it"?
16:27:54joetooAnyone know if there is 1) any way to play xvid or similar, 2) any plans to add such support, or 3) that this just ain't gonna happen?
16:28:29n1s1) if someone codes it 2) not afaik 3) see 1 & 2 :)
16:28:44joetoowell, I have some experience in embedded programming, but I've never tried to do it portably, nor have I ever worked with codecs.
16:29:35BigBambigood time to start then
16:29:49n1sit is a good opportunity to increase your experience then! but expect it to be a _lot_ of work
16:30:29n1sjoetoo: any idea about how much processing power divx uses in relation to mpeg2?
16:30:36BigBambiI think most people feel that given Rockbox has very good support for MPEG 1/2 that the advantages of using xvid are very very small compared to the amount of work
16:31:07joetooI'm sure it's more, but we are also talking about very small screens and possibly low framerates.
16:31:12markunBigBambi: but with players getting faster, I see how it would be easier to just copy an existing file over without transcoding.
16:31:45BigBambimarkun: Sure - I'm not saying that is completely pointless, but hithertoo nobody has felt the advantage is big enough to bother to do the work
16:32:03BigBambijoetoo: very small screens sure, but also very slow processors and low memory
16:32:08markunjoetoo: maybe you could try to do some benchmarks on a PC, it might give you an idea how much more complex mpeg4 (xvid/divx) decoding is.
16:32:24n1smarkun, BigBambi: and on the beast we have tv out so there's more use for larger (as in res) files :)
16:32:33BigBambivery true :)
16:32:44joetooin my case, I have a 2GB player, with microSD (not HC). Though I gather using rockbox enables micro SDHC. So storage space has been a concern for me.
16:33:01n1s(well, the ipod videos have tv out too but afaiu it's tied to the broadcom chip)
16:33:30joetoomarkun: that might make sense. I could transcode something to the right size, then see what the cpu load is with different codecs.
16:33:41BigBambijoetoo: Enough of a concern to write an xvid codec for Rockbox?
16:34:06joetoowell, writing one is a bigger deal than porting one to a different libc
16:34:16markunjoetoo: someone got started on it a while ago, but I don't know if you could reuse any of his work: http://www.rockbox.org/tracker/task/2848
16:34:31BigBambiThat is all my point is - if the difference matters enough to you then you will do the work. So far the difference hasn't been important enough to anyone
16:34:47JdGordonjoetoo: ignore them... do it and the worst that will happen is that you dont get a usable framerate, in which case its likely someone will come and help optimize it...
16:35:06markunjoetoo: ignore JdGordon :)
16:35:08BigBambijoetoo: OK, port. But given things like no floating point, no malloc, it could (I say could, I don't know) almost be writing
16:35:44BigBambijoetoo: I'm not trying to discourage you incidently, I'd like to see it personally :)
16:35:44*JdGordon goes back to wondering how the hell to do a recent bookmark list :(
16:36:49joetooThe framerate issue is another concern. It is imaginable that at a low framerate, the deltas between frames would be huge no matter what you do. Some codecs may not save much space or may have very poor quality at low frame rates.

17:24:49joetooI see that w.r.o says that gcc-4.1.0 fails to build Rockbox properly 'on some inline assembly and with the Tremor codec'. Do we know if this continues to be true for all gcc >= 4.1 ? I managed to build for sansa e200 without errors using 4.1.2, (although I have not tested the binary). Is this a platform specific problem due to the inline asm? Or is it that my binary likely won't run (or will brick my sansa) ?
17:26:56joetooHmm. Perhaps that was a dumb question. The webpage seems to have a recent modification date.
17:29:21n1sjoetoo: it can be platform dependant, I have tried (and built working rockbox) with gcc 4.0 4.1 and 4.3 for coldfire for example although they required some small tweaks to the code and compiler options to work
17:33:06 Nick JdGordon is now known as JdGordon|zzz (n=jonno@rockbox/developer/JdGordon)
17:33:14joetooOK, so it may be that using the recommended compiler is only absolutely necessary when testing code before submitting patches.

17:36:37BigBambiJdGordon|zzz: For me, yes as I only use the filetree

18:24:36jhMikeSoh, in the patch
18:24:48bughunter2yup
18:25:03bughunter2just curious about why there is no semaphore release there?
18:25:32jhMikeSshouldn't have to because iff die is set to 1, then we signal the synth and wait for the thread
18:26:05bughunter2jhMikeS: yeah, so why isn't the semaphore released? i don't know anything about the piece of code there, but i was curious so i checked out the pastebin link :P
18:26:40jhMikeSbughunter2: you probably should look at context. if die=1 then the sem isn't waited on again.
18:27:01bughunter2jhMikeS: that's true, but i see it as malloc/free more, like, if you alloc, you should free
18:27:04bughunter2isn't that the same with semaphore?
18:27:17bughunter2perhaps a bit of a newbie question, i haven't worked with semaphores really
18:27:21jhMikeSwait/release don't allocate memory, they just change the count

20:41:59gevaertsjhMikeS: that's what we're trying to find out
20:42:02 Part J-23
20:42:51gevaertsvitja: ata_init() is fine. My guess is that there's something wrong with the SYS_USB_CONNECTED_ACKs
20:43:19vitjawhat's that?
20:43:24jhMikeSgevaerts: ok, I don't mean to poke too much :) I just had curiosity piqued.
20:44:15Nico_Pgevaerts: IIRC appsversion is set using the svnversion script
20:44:16vitjagevaerts: here it is: vitja/usb-tcc77x.c">ftp://stop.qc.to/vitja/usb-tcc77x.c
20:45:23gevaertsvitja: usbstorage calls usb_request_exclusive_ata(), which sends a USB_REQUEST_DISK event to usb_queue. The handler for that sends SYS_USB_CONNECTED to all queues, so all threads get a chance to exit if needed. They are expected to send a SYS_USB_CONNECTED_ACK back
20:45:57vitjaokay will take a look tomorow
20:46:01gevaertsWhen all of those have come in, exclusive_ata_access is set to true, and usb_exclusive_ata() returns true
20:46:40gevaertsvitja: any idea if this should work as-is on cowon D2 or Logik DAX?
20:46:41vitjanow I'm going to commit some changes in header that will allow to compile driver
20:47:05vitjagevaerts: some old piece of code worked the same way on D2 so I think yes
20:47:18gevaertsok. That means I can test as well
20:47:19vitjathe one proble in D2 is it doesn't have TMODE it has MODE
20:47:55gevaertsDo they behave the same? i.e. can I just replace TMODE by MODE?

21:24:03shotofaddsvitja: that looks good to me. don't forget to fix system-tcc780x.c!
21:24:10gevaertsamiconn: I think I tried it at devcon, but I'm not sure now. Definitely PP indeed
21:24:54LambdaCalculus37So the new commits for m200 and Logik DAX should allow a normal build to compile without error, correct?
21:25:01gevaertsamiconn: have you tried a PP5020 device with it? I can't remember
21:25:43amiconnYes. Same problem, a bit less likely though
21:26:14amiconnThat might just have been due to the different (better?) cable of the H10 (vs. ipod cable of my mini)
21:26:29amiconnI should probably try it on the Photo as well (same cable as the mini)

21:33:04shotofaddsLambdaCalculus37: I wouldn't expect it to work. Reading works if every sector was written to the device sequentially.. but that's rather unlikely in the real world!
21:33:10vitjagevaerts: should work from bootloader call usb_test() after ata_init() in bootloader/telechips.c

21:38:34vitjashotofadds: there is also usb interrupt handler missed
21:39:01linuxstbamiconn: It's just arbitrary for now - I chose the same values as the iFP as a starting point.
21:39:29vitjashodanX: that should be called USB_DEVICE()?
21:40:01vitjashodanX: sorry
21:40:05amiconnAh, hmm. My first idea was that those targets shoul duse 32KB plugin buffers, same as archos
21:40:26amiconnBut then I'm not 100% sure anymore, because of arm code size vs. SH1 code size
21:40:39amiconnPerhaps 48KB would be a good size
21:40:42shotofaddsvitja: you mean USB_DEVICE vs. USBD_IRQ? I really don't mind which we use .. just so long as they're the same!
21:40:44linuxstbamiconn: Plugin building is disabled for now anyway, so when someone gets them building, we can see how much RAM is needed.
21:41:08gevaertsamiconn: another difference is that these are flash targets, so they can probably get by using less buffer
21:41:28shotofaddsvitja: none of the existing 78x handler names have a _IRQ suffix, so I'm reluctant to change that.
21:41:38amiconnCodecs are different, of course. They need a bit more unless you want to do without many of the codecs...
21:41:45vitjashotofadds: should be nice
21:42:09amiconngevaerts: Even on the flash targets there are a few reasons to keep the main buffer large

21:45:01gevaertsshotofadds: actually, no. the main build should also work

21:45:38jhMikeSamiconn: Anything AS3514 runs i2s as master, the Wolsons run as slave iirc
21:45:45shotofaddswhy do we need charger detection for USB anyway?
21:45:49gevaertsusb detect and charger detect need to be separated
21:46:05amiconnjhMikeS: Nope. In the ipods, the wolfsons run as master. That's why I was asking ... ...
21:46:08vitjaamiconn: I mean make usb detect return USB_INSERTED

22:57:21webguest44Hi everyone, I'd like to upload a theme to the Rockbox wiki and I need write permissions to do this. Could anyone give me these permissions please? The theme is basically an update of my previous Plain Text theme for e200, but uses viewports to display different parts in different color and WORKS with current builds.

22:59:38saratogaamiconn: the ac3 codec's windowing code could probably be replaecd with the ASMed one used by WMA/AAC as well

23:00:04webguest44Aha, my nickname is incorrect (I used the web-based IRC client). So my nickname is JiriTechet and I only hope my theme won't be regarded as a spam :-)
23:00:17saratogabertik: any chance you tested the OF?
23:00:26saratogai'm curious if we beat any retail PP firmwares yet
23:00:37domonokywebguest44: done
23:00:55amiconnsaratoga: On ipod 1st/2nd Gen we already did
23:01:04webguest44Wow, that was fast, thanks!
23:01:12saratogaamiconn: thats right I'd forgotten
23:01:13gevaertssaratoga: my ipod mini 2g with cf mod went from about 12:45 to 15:30
23:01:25gevaerts(320kbit mp3)
23:01:27amiconn(against runtimes stated by manufacturer, not measured)
23:01:57bertriksaratoga, no, I haven't tried the OF yet
23:02:20saratogai should test mine, but i just don't want to deal with unmodding the bootloader and such
23:02:37saratogait was annoying enough to get the bootloader off and the database refresh gone the first time
23:02:38amiconnWhy would you need to do that?
23:02:54saratogapresumably not having the Sandisk bootloader could change things
23:02:58desowin_saratoga: I think we already did for sansa e200, I might do test with OF now, butthe problem is there's no battery_bench plugin in OF ;)
23:03:10saratogasince the hardware init is different
23:03:26saratogadesowin_: play music and record on the line in at 8khz and 8 bit
23:03:32amiconndesowin_: Hook it to your pc soundcard, and start recording. 8kHz mono is sufficient
23:04:17saratogaactually i need to test if removing the OF bootloader changes things, that could give us some clues about hardware initialization on the sansa
23:04:20bertrikI can't find a claim about runtime for the c200's on the sandisk website
23:04:43 Part domonoky
23:04:45*amiconn thinks this comparison would probably be easiest on H10
23:04:46saratogabertrik: you can probably get a good idea just by scaling the 20 hours for the e200 by the change in battery size
23:05:20 Quit webguest44 ("CGI:IRC (EOF)")
23:05:32amiconnNo database refresh, and UMS for easy swap between rockbox bootloader and OF
23:05:47bertrikthat would be 20h * 530 mAh / 750 mAh = 14:08
23:06:09amiconnAnd H10 (small) runtime isn't great in general, so no excessive waiting ;)
23:07:34bertrikBTW, the AS3514 inside the PP5024 allows undervolting from 1.2 down to 1.05V, I'm sure runtime can be extended even more that way
23:07:58saratogafor what its worth, the ABI review says Sandisk says 15 hours and the reviewer claimed 13 hours (c200)
23:08:03funmanPP5024 is the Sansa c200 SoC ?
23:08:14Bagderfunman: no, the e200

23:30:27LloreanBagder: Regarding the upcoming release, I'm so out of touch that I have no idea what's been happening but I wanted to drop a reminder regarding default settings that may need changed (larger limits for files in folder, playlist length, and default enabling of dircache)
23:30:34Nico_Psaratoga: in the commit message for MP3 synth filter on COP, you mention a diff between test_codec and real world perf increase. why is there one?
23:31:11 Quit dabujo_ (Read error: 110 (Connection timed out))
23:31:20LloreanNico_P: I thought even when it was first introduced it wasn't expected to mirror real world performance
23:31:44saratogaNico_P: test_codec doesn't use the buffering, DSP or playback code, so the split between the processors isn't realistic
23:32:16saratogain reality the CPU is still much more worked then the COP, so the near perfect scaling with cores in test codec is unrealistic
23:32:24Nico_PI see
23:32:47Nico_PI wonder if we could switch e.g. buffering to the COP
23:33:09saratogaNico_P: I'd very much like to make the buffering code thread safe, but its beyond my abilities i think
23:33:27saratogaparticularly the insert pcm function
23:33:56saratogai guess thats playback more then buffering
23:34:02Nico_Pyes, it is
23:34:29 Join MarcGuay [0] (n=chatzill@ip216-239-81-208.vif.net)
23:34:36saratogasince buffering has to be synchronized with decoding (so the input buffer doesn't get overwritten while its in use), putting buffering on the COP would not be my first choice
23:34:37amiconnLlorean: Imho the files per folder limit is already too high
23:34:45 Quit funman ("leaving")
23:34:49saratogahowever, if its easy to do, I would certainly like to see it done
23:34:51*amiconn lowers it immediately on any new target
23:35:02Lloreanamiconn: For the average user, though, it's not.
23:35:05saratogathen maybe we could put all of the codecs on COP
23:35:17LloreanIt shouldn't be raised for archos, but many people seem to lump all their files in one folder, or have many, many, many artist folders
23:35:19saratogaand leave playback on GUI on the CPU
23:35:31LloreanBut on swcodec we have the RAM to spare to set it somewhat higher, in most cases.
23:35:47LloreanA very large portion of us agreed this would make sense for the release branch, at least.
23:35:55LloreanWhen it was discussed some time ago
23:35:56amiconnIt is already a lot higher than is sane to have actual files per folder
23:36:02saratogaputting it higher on the release would be nice, mostly just so that people don't complain about problems with it
23:36:02LloreanPeople aren't sane, though.
23:36:20saratogamost sensible people will be using SVN builds anyway I think
23:36:23amiconnIt's set to 1000 by default. I usually lower it to 300
23:37:56saratogaNico_P: basically, data flows from the buffering code, to the codec, then to playback/DSP, so ideally we'd pick one point along that chain and move things to the COP
23:38:29saratogaright now mp3 moves to the COP and then back to the CPU so theres two transitions which is a bit ackward (but not a serious limitation for MP3 at least)
23:38:43Lloreanamiconn: Maybe just for the 80gig iPod then, but we definitely have users who from time to time report bugs about the error you get when it's set too low.
23:39:04LloreanWe can't expect users to be sane, so we need to set insane defaults when we can spare some RAM for it, and document that "lowering it could increase battery life"
23:39:11gevaertsWhat error message do you get?
23:39:28amiconnsaratoga: Didn't you say that mp3 performance on gigabeat was rather bad? Was that F/X or S?
23:39:47*amiconn just checked on the beast, and got 800% realtime with 192kbps mp3
23:39:48Lloreangevaerts: Something like "Directory buffer full" maybe? I can't remember exactly
23:40:01amiconnThat's ~33MHz for realtime
23:40:08saratogaamiconn: I looked at the F
23:40:14amiconn(beast running at half speed in svn)
23:40:18*gevaerts thinks that rephrasing the error could help, at the risk of angering our beloved translation maintainer
23:40:26saratogai don't remember what MP3 was, but WMA/AAC/Ogg were quite poor
23:40:32saratoganeeding nearly 2x the clock speed as PP
23:41:02amiconnWell, the beast needs less for mp3. No WMA or AAC to test with. OGG I can check
23:41:13saratogai'd expect a huge gain on the beast
23:41:19saratogait has the fast multiplier
23:41:25saratogaand much bigger caches
23:41:50rashergevaerts: As long as it's not done in the 3.0 branch, I'm down with it
23:42:33saratogaa fixed point mul on ARM9 is 7 cycles (of which I think only 3 are pipelined) while its just 3 on the beast (all pipelined)
23:42:43Lloreangevaerts: Possibly for future releases
23:43:23gevaertsrasher, Llorean: it would be nice for 3.0, but 24 hours is not really enough for translations to get updated I guess
23:43:27LloreanBut I feel that in the release version, we should have defaults lined up with the shotgun approach: Solve potential problems, with the option to disable things to increase battery life (rather than having things optimized to increase battery life but require referencing the manual just to be able to access your music period if you're a non-expected setup)
23:43:48gevaertsLlorean: I think I agree
23:44:05*Nico_P agrees too
23:44:28LloreanAnd since this may be the last hour or two I have on the 'net before the release, I figured I'd try to drop by and re-mention this.
23:44:58saratogaARM9 is a bit weird since its still all terrible like ARM7, except with slightly better load/stores and much higher clock speeds (which actually eat up the load store performance if you don't have IRAM)

23:45:41saratogai expect once we get slower ARM9 cores like the AMS chips, it'll become necessary to pay attention to ARM9 performance
