00:31:27rocktriangleAlright then
00:31:29rocktriangleI'll try that
00:31:30rocktriangleThank you
00:32:03rocktriangleBy the way, I also got a warning, who could I go to to have it deciphered? At the top it said *PANIC*
00:32:05 Quit gxk (Ping timeout: 245 seconds)
00:32:59bertrikyou could post it on the bug tracker
00:33:15bertrikthere are several people here that can decipher it
00:33:54gmaxwellfreqmod: if you really only have 9k of stack, then you're almost certantly going to need to go the NONTHREADSAFE_PSEUDOSTACK route, and stub in the parts required to get some heap to that global.
00:34:35gevaerts*only*? That's one of the larger stacks in rockbox!
00:35:50gmaxwellfreqmod: Opus is recursive. And while I don't doubt that there are plenty of low hanging fruit to cut down on the stack usage, the PSEUDOSTACK switches almost all of it to heap.
00:35:53bertrikare we really that tight for memory that we can only afford 9k for stack?
00:36:16gevaertsWe can increase it if really needed of course
00:36:32freqmodis it a problem to just create another thread with larger stack?
00:36:38freqmodwith thread safty etc
00:36:46Tornethe number of threads is hardcoded
00:36:48gmaxwell(downside being that it makes the codec totally non-threadsafe)
00:37:07Tornecreating another one means there's another thread, with stack, in existence *all the time*
00:37:07gevaertsI don't think thread safety is an issue here
00:37:11Tornenot just when that codec isbeing used
00:37:25gmaxwell(well, and its less well tested, because we've only really ever used it for the c55 DSPs which don't even work at the moment)
00:37:34freqmodi am going to a cabin without internet for the next week
00:38:01gevaertsgmaxwell: how much stack do you expect is needed normally?
00:38:18freqmodso i may try to fix something of it, but we are mostly trying to work to get the cabin freshly painted etc.
00:38:40gevaertsI mean, if it's 16K, we can increase it without too much discussion, if it's 128K, that's pretty much a dealbreaker
00:39:01bertrikfreqmod, can you push the missing ogg stuff I mentioned?
00:39:14freqmodhow much memory is available for codec heap?
00:39:16gevaertsTorne: are you sure about that?
00:40:08gmaxwellProbably more like 20-30k. Been a while since I checked. Certantly not 128k.
00:40:17Tornegevaerts: er, i thought so.
00:40:18freqmodbertrik: pushed
00:40:22bertrikthanks
00:40:27Tornegevaerts: do we allocate them with buflib now?
00:40:30freqmodand i have also made enough parsing so the codec starts on target
00:40:37gmaxwell(also I was mostly lookingat encode and decode; and you only care about decode at the moment)
00:40:38freqmod(and produces stack errors)
00:41:08gevaertsTorne: we have a fixed (maximum) number of threads, but IIRC for plugins and codecs those are more or less dynamic
00:41:13amiconnTorne. gevaerts: The *maximum* number of threads is hardcoded, the number of running threads is not
00:41:53amiconnThere are a few spare slots, so codecs and plugins can start a background thread if necessary (e.g. mpa.codec does this on pp)
00:41:54Torneamiconn: sure, i didn't mean they were literally running all the time
00:42:02Tornebut the *stacks* exist
00:42:05*freqmod read something in the codecs.h about spawing threads with the stack as a parameter
00:42:08Torneand their context
00:42:12bertrikI wonder if we can allocate the stacks with buflib now
00:42:13amiconnNo they don't
00:42:17gevaertsTorne: the stack will be allocated in the codec buffer somewhere
00:42:23amiconnOnly the context stores exist all the time
00:42:46*freqmod are going to sleep
00:43:15amiconnThe main disadvantage with an extra thread is that the stack either cuts down codec iram, or is located in dram, which is a disadvantage as the main codec thread's stack is in iram already
00:43:43gevaertsfreqmod: check CODEC_SIZE for the total (code+heap) size you get
00:44:44gevaertsI'd say that if this NONTHREADSAFE_PSEUDOSTACK works, it's the best solution
00:45:13amiconnWhile from this point it doesn't matter whether you create an extra thread with big iram stack or allocate them in iram another way (whatever that #define is), the latter is the easier way as you don't need an extra thread
00:46:35gevaertsRight, codec_stack is IRAM, so yes, increasing it is tricky
00:46:37amiconnA thread context isn't that large in rockbox, thanks to cooperative threading
00:47:02amiconn(meaning we don't have to save scratch regs)
00:49:24gevaertsDo we have numbers somewhere on how much IRAM we have left on various targets?
00:49:45bertrikfreqmod, pretty cool to see it working in the sim, nice job!
00:50:29gmaxwellIn any case if there are bugs w/ NONTHREADSAFE_PSEUDOSTACK, I'll fix them if you find them. We specifically put that in for memory limited platforms that didn't have allocators or multithreaded decode.

00:55:06saratogagevaerts: http://www.rockbox.org/wiki/CodecMemoryUsage
00:56:45gmaxwellHE AAC using 500k ?!@#! well, okay I'm no longer worried about opus.
00:57:22saratogaAAC HE uses a lot of memory
00:57:30saratogaalso, libfaad is not very efficient
00:57:47saratogaalthough we've patched it up a lot
00:58:18saratogaaac in general is a pretty bloated format
00:58:37saratogai guess design by committee and all that
01:00
01:00:57gevaertsIt's mainly the IRAM bit that's really constrained here. We can't increase codec_stack much (if at all, I guess) without moving it to slower RAM (for every codec)

01:01:59 Quit gxk (Ping timeout: 255 seconds)
01:02:04bertrikwe don't really sync codecs often with upstream, do we?
01:05:41saratogabertrik: do you mind if I just disable the backtrace on AMS for now?
01:06:14bertrikno, I don't mind, seems to be giving more problems than solutions currently
01:11:03saratogaok i put a FIXME comment in with the disable, hopefully the backtrace can be made to work better with AMS in the future
01:12:06saratogaon arm the panic screen calls "disable_interrupt(IRQ_FIQ_STATUS);" but never reenables interrupts, maybe we could enable them at the end just to be safe?
01:13:03bertrikI don't see why we need interrupts at that point anymore
01:13:47bertrikthe only thing we do is wait for a button (and I suppose we can do that without interrupts)
01:14:38saratogasince the 30 second hold doesn't reboot the power, something is not getting enabled
01:14:48saratogayou think interupts aren't it?
01:15:01 Join gxk [0] (~gxk@bzq-79-180-216-196.red.bezeqint.net)
01:15:35saratogaoh crap
01:15:38bertrikluckily I haven't been in that situation myself yet, and I don't know exactly what happens
01:15:38saratogaits the ROM clock
01:15:48bertrikoh, I thought we re-enabled that already
01:15:50saratogathe ROM clock is off normally, and we turn it on during reboot
01:16:01saratogaso if you don't make it through reboot, you have no clock
01:16:08saratogaand hence no hold power to reboot
01:17:24saratogaI can #ifdef the ROM clock enable into the start of the abort handler (which is a bit ugly but safe), or just leave the clock on all the time
01:17:27saratogawhat do you think
01:17:35saratogamaybe we should just leave it on to be safe ...
01:18:19bertrikI find it peculiar that we somehow seem to be able to disable the hardware power-down mechanism
01:18:56bertrikyes, I'd rather leave it on (and waste a miniscule amount of battery runtime) if it helps us from the current situation
01:18:58saratogaclearly the "reboot" doesn't fully reset the SOC's state
01:19:03saratogaok i'll do tht
01:20:44bertrikwhich is a hardware design flaw IMHO

09:50:33JdGordonnothing to worry about, no wiki hacking
09:50:41JdGordonjust annoying permissions
09:50:50[Saint]Oh....right. I see, you should remove that page then :)
09:50:56Zagorah, the spam was done in the user's own page?
09:51:01JdGordonyes
09:52:06Zagorthere's another far simpler fix for the bulging WikiUsersGroup page
09:52:09[Saint]I'm pretty sure it never used to be that way, though. He wasn't in the wikiusersgroup, so shouldn't have had a users page to begin with.
09:52:57Zagorwith the latest foswiki upgrade, there's a new feature which inverts the access scheme. so instead of adding people who are allowed to write, new registrants are added to a block list from which we remove those who are approved
09:53:09[Saint]As always, there's a chance I'm misremebering, but as I recall the user's page should be generated on their first login.
09:53:37Zagor[Saint]: that was a bug. all registrants should get a user page immediately.
09:53:58Zagorone can argue wether he should be allowed to edit it though, since that allows spam.
09:54:04[Saint]Ah, hmmm. It was a "nice" bug, then :)
09:54:59[Saint]Well, that's good. I guess. I can't say I didn't want an excuse to do a mass wiki cleanup though :)
09:56:11JdGordonI say leave it as is unless it becomes a bigger problem
09:56:19JdGordonone in 5 years is not an issue worth worrying baout
09:57:56[Saint]Well, yeah. As I said above, though, I kinda wanted the excuse to do a big purge of the wiki. Make sure its all up-to-date and functional, remove outdated content, and users that haven't ever made a singular edit.
09:58:29[Saint]Its no biggie, it would've been a daunting task, but the wiki is definitely the area of the project that gets the least attention.
10:00
10:00:09[Saint]Primarily, the user registration needs to be functional (well, "need" is a strong word, but it sure would be nice). As it is, its pure luck whether or not adding a user to the usersgroup actually grants them write access.
10:01:13[Saint]And if you select "edit" on the wikiusersgroup (in Chrome, for sure) the "quick add" dialogue disappears and 17 miles of whitespace gets added to the bottom of the page.
10:03:19[Saint]JdGordon: you're not by chance also BabisManouselis, are you? :)

12:05:04gevaertsI could send you one
12:06:30wodzMaybe I can ask bohoon. That way we will avoid international shipping
12:15:29[Saint]I have a couple of iPod Colors surplus to requirement...
12:15:58gevaertsYes, but you're not ideally located shipping-wise :)
12:17:26gevaertsI seem to have 8 PP devices, I'm sure I can miss one of them
12:17:47wodzby the way, currently plugins use main stack AFAIK. This will be problem if we consider multiple plugins at the same time
12:18:25wodzwell, I can always ask Torne to send me back my mini1g
12:19:54TorneOh, yeah.
12:19:55Tornesorry about that.
12:20:14Tornei can do that whenever, really
12:20:38gevaertsThat's an issue to keep in mind, yes. It being a problem will depend on how we do multiple plugins. I'm e.g. not convinced we want more than one "regular" plugin, I think we're more interested in e.g. battery bench not having to stop, or wps visualisation plugins (both of which will use either separate threads or callbacks), or moving out bits of the core (which would work more as a library I guess)
12:22:10wodzcurrently I completely ignored library support
12:22:21gevaertsOh, of course
12:22:21wodzI mean the got and friends
12:22:50Tornewodz: well, we don't actually ahve todo it that way
12:22:58Tornein fact we probably won't
12:23:04gevaertsWhen I say "more as a library" I also don't necessarily mean "the way a shared library tends to work"
12:23:05Tornesince i doubt we want link by name
12:23:51gevaertsIn fact, I'm not sure if "library" is the proper word to use there :)
12:24:34Tornei would imagine we would do that kind of thing using a single symbol that pointed to a struct like plugin_api
12:26:56Torneanyway we can work that stuff out later :p
12:27:29wodzsure. First thing is to have working all plugins on all platforms

13:54:33gevaertsOK, the html manual still builds for me. This seems to be server-side
13:54:43gevaertsZagor, Bagder: a job for you?
13:55:04kugelphow about one thread per plugin?
13:55:04Zagoryep, I'll try to get a peek at it today
13:55:41gevaertskugelp: doesn
13:56:19gevaertskugelp: doesn't the drawing API assume it's only called from the main thread?
13:56:41kugelpno
13:58:13kugelpthe scrolling thread draws too, even concurrently
13:58:40gevaertsAnyway, I'm not sure what problem this would solve exactly. For fullscreen plugins, only one can run usefully at a time anyway, so others would have to be notified in some way about not doing anything, while for hypothetical other (new) plugin types things like button handling haven't been worked out at all yet
13:59:10gevaertsUnless proven otherwise I'm still of the opinion that some sort of callback system will work better
14:00
14:04:24wodzFiguring out why quite a few plugins misbehave on PP is more important for now.
14:04:39kugelpjust saw you talked about problematic stacks
14:04:57wodzI just pointed out that this will be something to talk about
14:05:45wodzIt is not for now. For 'many' plugins at once we will need buflib support to allocate space also

15:18:43slowdowi should point out at that i'm happily using rockbox every day on 2 devices, and that i love it.
15:18:51TheSevenwodz: so you suspect a core bug, not a target driver one?
15:18:55slowdowthis Ipod is perfectly usaable.
15:19:03slowdowi just use the fallback image to copy data
15:19:12slowdowand then boot to the new builds for use. no biggie

15:19:27slowdowbut it is a bit annoying, and for your common or garden user, a bit of a faff?

15:20:18TheSeventoo bad these builds are like half a year apart
15:20:25TheSevenso we can't just pinpoint a change easily
15:20:34wodzTheSeven: There are reports of misbehaving on amsv2
15:20:47TheSevenwell, amsv2 is the same OTG, right?
15:20:54wodzother soft usb targets are rare unfortunately
15:21:00slowdowive got a small pile of builds i've archived, the standard builds were working up to a point a few months ago
15:21:27TheSevendoes the classic currently use funman's shared driver?

18:57:46slowdowon the 2nd pc, (the same pc as mounted in Ubuntu), the ipod is now mounting in win7. it mounts as "rockbox media player" - however, when plugging it into my main laptop it still fails, and mounts as Apple iPod Classic USB Device" with 0bytes.
18:58:31slowdowis there a way i can force my other laptop to mount the ipod as "rockbox media device" .. maybe that'll work and its a problem between the Apple driver and the later versions of rockbox?
19:00
19:01:34slowdowstrange this is, i plugged it into another laptop, that's never had itunes or anything fruit company related installed, while it was running rockbox, and it still installed the driver as "Apple iPod Classic USB Device"
19:03:05yuriksslowdow: http://support.microsoft.com/kb/315539
19:03:20yuriksslowdow: do that and remove the device, then let it detect again when you plug it in
19:13:53slowdowthe device isnt shown, i've run set devmgr_show_nonpresent_devices=1, and sleected show hidden
19:14:23slowdowits only shown when its connected. is it ok to remove the driver while its connected and therefore visible?
19:22:58slowdowok, removed the apple driver, re-plugged, it's now called "Rockbox media player" (bad capitalisiation included) but it still mounts as a 0byte drive.
19:23:29slowdowand crashes the Ipod.

19:27:14slowdowso... now, i've got one machine that mounts 0823817-120718 in win7 and Linux. and one that won't mount in win7. (typically, the fail machine is my main machine)

23:07:10bertrikfunman, I fixed some stuff regarding metadata parsing and elapsed time (so the progress bar shows correct progress), but haven't been able to make it run on target yet

23:10:20bertrikbut the latest stuff from his repo runs in the simulator
23:11:54gmaxwellI see he's still using VAR_ARRAYs.. so it's probably running into the stack usage issues that were mentioned on the actual target.
23:13:26funmanbertrik: maybe try running the sim in valgrind to see errors non-fatal in the sim but fatal on target
23:14:01gmaxwellI mean I don't think there is any doubt. if you only have 9k stack then I'm pretty sure that isn't enough for a VAR_ARRAY configured build.
23:14:14bertrikgmaxwell, so the new plan should be to use the NONTHREADSAFE_PSEUDOSTACK thing instead of VAR_ARRAYS, right?
23:14:35 Quit dfkt (Quit: -= SysReset 2.55=- Sic gorgiamus allos subjectatos nunc.)
23:14:37gmaxwellRight, and it'll need a little twiddling because you'll need to allocate some more heap for that.
23:15:23bertrikunfortunately, the whole memory mapping thing on rockbox is a bit of a mystery to me
23:15:39bertrikwe have all kinds of weird hacks to steal memory here and there
23:15:53gevaertsWe do?
23:16:18gmaxwellwell, it allocates heap for the decoder state already. Stubbing out the allocation functions in NONTHREADSAFE_PSEUDOSTACK and setting the global to point to some more heap that comes out of that codec_malloc call should be enough.
23:17:28bertrikgevaerts, what does codec_malloc do?
23:19:00gevaertsbertrik: at first sight, it malloc()s memory from the leftover codec buffer
23:19:13bertrikrunning the sim with gdb always gives me weird issues
