#rockbox log for 2010-01-09

00:00:02Spaceghostare different things
00:00:25AlexPSpaceghost: I don't know what you mean by "sports pictureflow"
00:00:54Spaceghostsorry, I used the google translate that time xD
00:01:00AlexPhehe :)
00:01:05Spaceghostwasn't good to trasnlated
00:01:05pamaurySpaceghost: I'm not sure but that's was just a joke to say that the pictureflow plugin was useless
00:01:25Spaceghostahh
00:01:27Spaceghostok
00:01:41*pamaury don't remember who maintain the pictureflow plugin for fun
00:02:12JdGordonamiconn: even if the selection list can be stored on the files (or by the list caller in general), there is still 2 problems
00:02:38JdGordon1) the list needs to know which to draw as "selected" which could be done via the text callback through a function call (yuck!)
00:03:02JdGordonand 2) a way to enumerate the selected list after (might not be needed to be done in a generic way though)
00:03:14Spaceghost* pamaury wonders how many stupid-things-like-the-nike+-ipod-kit the iPod Touch/3GS/... supports ! There are as useless as the pictureflow plugin ;)
00:03:47Spaceghostthere
00:03:57*JdGordon slaps Spaceghost
00:04:02JdGordonpf is very useful!
00:04:19pamauryah that's you JdGordon who maintain this funny plugin
00:04:29GodEaterJdGordon: he was quoting pamaury
00:04:34AlexPUnhelpful last worked on it IIRC
00:04:35GodEaterhe didn't say that personally

00:04:42SpaceghostI did not say that
00:04:48*pamaury prepares to being slapped
00:04:52*JdGordon sneaks away
00:05:05JdGordonand no, i dont think i've ever touched the pf code
00:05:13*B4gder takes all the blame. sorry guys, my fault
00:05:23AlexPAh, the fall guy is here :)
00:05:52*B4gder wears shades and earpiece
00:05:54Spaceghostpamaury, do you think that the Nike accesory not helpful?

00:06:45pamauryI'm wondering how useful is it ? I mean, how many people really use this ?
00:07:15 Quit ifonefox (Remote closed the connection)
00:08:24SpaceghostI think it's an interesting idea, pity it is so exclusive and limited
00:08:51JdGordonthere is no correlation between somethings usefuleness and how much its used... *especially* in apples world
00:08:55 Quit evilnick (Ping timeout: 180 seconds)
00:09:18pamauryJdGordon: do you think it would be useful to implement item selection in the listview ? Would other areas (apart from *would be* multi-select) use it ?
00:10:24pamauryit costs money to develop it so apple would sell it only if people buy it, no ?
00:11:25*JdGordon was more thinking about the numerous fart iphone apps...
00:11:38JdGordonbut yes, multiselect is for sure worth implementing
00:12:59pamauryWould it require lots of work to have a listview with selectable items ?
00:16:15bertrikpamaury, I'd say a moderate amount
00:16:59bertrikFirst we'd have to add support to do the multi-select (agree on a way to do this in the UI)
00:17:16 Quit jgarvey ("Leaving")
00:17:55***Saving seen data "./dancer.seen"
00:17:58pamauryHow exactly it works ? I mean, a listview needs a state, when you browse fil you're in a listview with an associated state. But when you do a context menu, there is a another list-view, so is the state of the previous one deleted ? (I know nothing of the gui part)
00:17:59bertrikSeconds, we need to think how for each action to do something meaningful when multiple items are selected and activated

00:19:41pamauryYes

00:25:50JdGordonpamaury: the tree and the context menu use different lists so the state is known
00:25:59JdGordon.. rememebered
00:26:41pamauryOk that's a per-list basis then.
00:29:01JdGordonmost of the work is on the callers side, not the list side

06:11:27Unhelpfulbetter still, special-case divisor-is-one and then never do the first iteration...
06:12:05ruckus1i've been having an interesting problem with my 5.5 gen ipod. i managed to rip its ribbon cable that connects the ipod with the hold button and the headphones, and i replaced it with another one. after i did so, the feature "pause on headphone unplug" ceased to work, and instead of pausing the music continues to play
06:12:39ruckus1does anyone have ideas what can i do to get it to work again?
06:13:04Unhelpfulruckus1: figure out what went wrong with your repair, i'd guess. ;)
06:13:22ruckus1Unhelpful: irony ?
06:13:31ruckus1i mean, the ipod works perfectly
06:13:33ruckus1otherwise
06:13:51Unhelpfulexcept that it can no longer detect the headphone disconnecting.
06:14:02ruckus1correct.
06:14:44ruckus1i'm thinking i bought a compatible ribbon from another ipod generation
06:14:54ruckus1but the ebay page doesn't say anything about it
06:15:29Batmanifestdestiwith the whole "sansa e200 series" support gor rockbox, does that include e260, e240 etc?
06:15:58Batmanifestdestifor*
06:17:10UnhelpfulBatmanifestdesti: e2xx v1 are supported. later revisions, which (thanks sansa) are not distinguishable from labeling or external features, are in development
06:17:48Batmanifestdestiwow, so I'd be sitting around going "hurr hurr, which one do I have?" until I found out I had the wrong one, eh?
06:18:06***Saving seen data "./dancer.seen"
06:19:32UnhelpfulBatmanifestdesti: well, no, if you can start it up, you can check the vendor firmware version. also certain sites sell refurbs that are reliably v1.
06:19:51Batmanifestdestioh, ok
06:20:08Batmanifestdestiso, with rockbox, you can boot it from the original firmware, right?
06:20:17Batmanifestdestithat's what the unstable port site says
06:20:24Unhelpfulso, if you're getting it used from ebay, you could ask the seller...

09:58:50arbingordonhello, I'm trying to install rockbox on my sisters sansa e250v2
09:59:04arbingordonbut I can't find the usb options under settings
10:00
10:01:18Unhelpfulamiconn: well, the lsr was a mistake anyway, and is fixed now. i found more things to debug when i got to the armv5e/v6 version that uses clz to align the inputs instead of a shift/compare sequence. i now have unsigned div, divmod, and two mod implementations working on beast and e200. signed already works on e200, but will need some fixups to parallel the ones i did for unsigned (the divider body inverts the divisor early, and obviously
10:01:18Unhelpful clz needs the positive divisor)
10:03:14Unhelpfuli've been looking for a good place to fit in a 1-divisor or pow2-divisor test... these were very nicely optimized in the APE version but the zero-divisor test already fits to an op that the new divider needs, so calculating divisor - 1 would only be used for these new tests.
10:03:55Unhelpfuland i'm still not sure it's really important to special-case these, although dividing by one of course perform abysmally, probably about 80-100 cycles, i'd think

10:24:41Unhelpfulit seems the best way to do things like swapping registers used, etc, in a macro is to wrap it in another macro? at least, this solution seems to work. the issue is that the armv5+ version needs the non-inverted divisor for the clz, but can still do the inversion early by storing to a different register and then using the divisor register as a scratch register.
10:26:06Unhelpfuland it works for signed on beast now, too. the only thing left to do is a signed version of the specialized mod-only function, and of course benchmarking these against each other and against libgcc's functions

10:50:13Spacecan I do a ISO image of that in linux to then can be restore?
10:50:49 Quit kramer3d ("Leaving")
10:54:33Unhelpfulamiconn: because trial subtraction takes one iteration per bit of output, while newton-raphson approximation of 1/d, with a good starting estimate, does a good deal better. it appears the sample divider does 2-3 N-R iterations to get a result that is close enough, and gets the last 2 bits or so via trial subtraction.

11:01:15tmztSpace: can't you just copy the mp3 files from the iPod's harddrive?
11:01:47tmztalso, iso is not a generic term for disk image, it's for compact discs, it's the iso9660 filesystem
11:02:03S_a_i_n_tSpace: though it's generally a good idea toback up files, everything *should* be fine as long as you don;t botch the install...
11:02:09S_a_i_n_tand that's pretty hard to do

11:04:12S_a_i_n_tif you're installing rockbox, it's probably best to start from scratch anyway...as the iTunes Database is shit.

12:01:45Unhelpfulamiconn: oh? how so? i tried to think of a way, but it doesn't seem possible to eliminate the possibility that the partial remainder will have the high bit set, but still fail the trial subtraction, and then have its high bit shifted out on the next iteration.
12:02:21pixelmaSpace: if you get your Ipod into disk mode you should be able to copy all files off if the filesystem is not damaged I believe. Then the music won't be lost but it will be hard to find and order the files correctly again (I don't have an Ipod so I'm not completely sure, just from what I heard about Ipods here)
12:05:52Unhelpfuland if the high bit shifts out, the next iteration will produce a correct partial remainder, but will not set the carry bit correctly

12:10:45Unhelpfulin a uniform distribution the numerator will have the high bit set half of the time. this is probably not the case very often in practice. for the APE udiv32_arm i optimized rather heavily in favor of the common case, so that it costs only one skipped branch. the one i'm working on uses a few more ops but handles the 32-bit numerator case without resorting to calling part of itself as a function

15:28:15mtstripwax: Great work on the mdct, Thanks :)
15:28:57stripwaxmt :) no problem. it's not there yet though..
15:30:07stripwaxin particular, I *really* want to investigate alternative pre/post twiddling steps, to elimate requiring different twiddle tables for different sizes (and/or unifying all tables into one/two tables, like Tremor has)
15:30:54stripwaxThat would also eliminate one of the remaining two "Init" steps (the mdct twiddle factors is one init step, the fft bitreverse/reordering index table is the other init step). Fft no longer has any twiddle factor init, cos that uses the same table as Tremor now
15:31:02stripwax(the same static/fixed table)
15:33:26mtI see. I really want to work on it, but it seems my college is trying to set a new record on how many hours/day they keep us there. (last sat ~13 hours :/ )
15:33:51stripwaxPah, that's nothing . This time last year I was working 42hour days at work! :)
15:34:02B4gderon the hiway!
15:34:14B4gderin a shoebox
15:34:25*B4gder sneaks off into -community again
15:34:25mtAh you win. :)
15:34:55stripwaxOne twiddle idea comes from a pdf I read, I'll dig out the link later on. Basically you can replace the current cos(2PI * (i+1/8)/N) pre twiddle with just cos(2PI*i/N), and replace the cos(2PI*(i+1/8)/N) post twiddle with cos(2PI*(i+1/4)/N)
15:35:08stripwaxNow that would mean the pretwiddle can share the same table as fft/tremor
15:35:42stripwaxthe post twiddle is still a different set of trigs though :( But you could actually reduce the size of the table at the expense of one extra complex mul per sample:
15:36:02mtNice. Could you add that link to the wiki ?
15:36:18stripwaxI.e. post twiddle by cos(2PI*i/N), then post twiddle again by cos(2PI/4N)
15:36:47stripwax(which is a constant dependent only on N, i.e. a single cos/sin factor required for each different N, as opposed to a whole new trig table for different sizes of N)
15:36:53stripwaxmt - yep, will do
15:37:48mtGreat. I must run now. btw, excellent code comments. ;)
15:37:53stripwaxhah, thanks! :)
15:38:08*mt heads off
15:39:00*stripwax wonders which will be better : trig table in ICONST data and four extra muls per sample, or trig table in ram and no extra muls per sample

15:44:11bluebrotherdomonoky: I was thinking about adding a new parameter with the rbutil version number when retrieving rbutilqt.php from the theme site. That way the theme site can react to the versions, like displaying a notice that a newer rbutil is required for the theme site.
15:44:16bluebrotherany thoughts on that?
15:46:38domonokyhm, does the theme site then need to know about rbutil versions ? wouldnt it be better the other way round ? ie a version in the themeoutput of rbutil.php ?
15:48:13 Quit stripwax (Read error: 104 (Connection reset by peer))
15:53:16bluebrotherwell, that would mean that rbutil needs to know what to display −− and it doesn't know about this.
15:53:51 Join stripwax [0] (n=Miranda@87-194-34-169.bethere.co.uk)
15:53:54bluebrotherbut we could add both directions :)
15:54:01domonoky:-)
15:55:01bluebrothermy idea was to maybe try to submit the svn revision of rbutil, so the theme site can say something like "rbutil svn > r12345 (version 10.20.30) required, your rbutil is r9999"
15:55:28bluebrotheri.e. it doesn't need to know exactly about rbutil but only which is the minimal version required to use the theme site.
15:55:40domonokybut how does the theme site know this ? hardcoded in the php file ?
15:56:08bluebrotherof course we could add more functionality around that later. No idea what useful applications are around, but well ;-)
15:56:45bluebrotherwell, the theme site obviously needs to know about the versions. Maybe a database table with a revision - error string mapping.
15:57:03bluebrotherthe php file needs to access the database anyway ;-)
15:57:24domonokysure it has access to the db, but we dont have this table :-)
15:57:34domonokyand someone has to maintain the table.
15:58:10bluebrothersure, but I guess this shouldn't change often.
15:58:36domonokyi think it would be better it rbutil just requests version x of the rbutil.php output, if it cant deliver that, it gives a error. And we just bump the version, when ever we change the rbutil.php output.
15:59:15bluebrotherwell, it's not only the output format of rbutil.php. It's also the parameters −− like changing the target names.
15:59:31domonokytrue
15:59:46 Quit saratoga_ ("Page closed")
15:59:53bluebrotherright now svn will request a target sansae200 while the last release will request e200. That was a source for that idea ;-)

16:00:39domonokyfor the targetnames, we should just rename the themesite targetnames, shortly before/after we release a new rbutil version.
16:00:54bluebrotherso instead of retrieving rbutil.php?target=e200 we could now retrieve rbutil.php?target=sansae200&rbutil=12345. Then the theme site can return an error if that revision number is too low
16:01:07*flyback falls over head
16:01:28bluebrotherand as old rbutil version don't send that number the theme site can simply tell that the version is too old too.
16:03:40bluebrotherthat's at least better than simply to tell that there are no themes (because the target name changed). The rename is still an issue with the build server binaries but that's a different thing.
16:04:19domonokysure, a better error-message would be nice. currently it could also tell you, that it doesnt know this theme :-)

17:15:15bertrikThe as3525 has two PLLs of which we currently use only one (PLL A). This results in a lot of clock frequencies being dependent on each other.
17:15:35bertrikMaybe we could get a bit more accurate by using PLL B just for generating the audio clocks
17:17:13bertrikbut that could have the disadvantage of drawing a little more current
17:18:52LloreanHow much is it likely to impact battery life?
17:20:18LloreanI mean, in my book "introducing as little error into the audio as possible" is a pretty high priority as long as we're still able to compare equally or favorably with the OF.
17:20:27LloreanThat is, once power management over all is done.
17:20:48bertrikI don't know by how much. I vaguely remember someone having done measurements on this (saratoga/buschel maybe?) but I'm not sure
17:21:49soapI assume nothing which could be runtime selectable? The option of "precise timing with less battery" vs "OF timing and OF battery life" ?
17:22:09LloreanDo we even match the OF battery life on Clip yet?
17:22:18LloreanI haven't paid attention but I thought last time I looked it was running short still.
17:22:28bertrikI don't think so yet, I'll have a look at SansaRuntime
17:22:49soapWhile it's a nice rule-of-thumb to try and compare favorably with the OF when it comes to battery life, if the OF "cheats" and degrades battery life at the cost of audio playback it's not really a fair comparison anymore.
17:23:03bertrikhm, there's no Clip runtime yet
17:23:13soapexcuse me. s/degrades/improves/
17:24:31Lloreansoap: Well, I mean if it's a significant (I mean 10% or more kind of numbers) reduction in battery life for something a majority of users probably can't hear, and it can't be user configurable, and it'll mean we'll probably always measure less than the OF in battery life we probably shouldn't do it.
17:24:42LloreanI mean optimizations for all of our compressed audio are accuracy vs performance.
17:25:04LloreanBut it really depends on how badly it affects things (which we won't know without some sort of testing anyway)
17:25:44bertrikI guess significantly less than 10% impact
17:26:13LloreanThen we should probably just go for it if it means fixing a notorious problem the OF has.

17:53:11FlynDiceso the tradeoff there is better ape performance for reduced runtime(using pllb for audio)?
17:53:49bertrikI think the options are: 1) keep the current scheme with about 0.15% pitch error (still better than OF) 2) use a PLLA frequency of 384 MHz (0.04% error@44.1 kHz), but sacrifice some boosted CPU speed (248MHz -> 192 MHz) and some battery life or 3) use a separate PLL (PLL B) at 384 MHz (0.04% error @ 44.1 kHz) for the audio clock and sacrifice some battery life
17:54:27FlynDiceyes that seems correct to me
17:54:41bertrikmaybe option 2) is even a bit better w.r.t. battery life because of the reduced boosted CPU speed

17:56:11*kugel thinks we should keep what we have now
17:56:34*FlynDice knew that's what kugel would say ;-)
17:56:40soap0.04% is below what Wikipedia is calling the threshold of perception. Could a bit more error be allowed to safe any battery life - or are there really only two good clocks to be at?

18:02:03saratoga_we'd probably get better battery life without them
18:02:12kugelwe need the voltage anyway
18:02:27kugelmany microsd cards don't work with lower voltage
18:02:49saratoga_is that actually related to the cpu core voltage or just because of how we switch it?
18:03:07FlynDiceI would tend to think its the switching
18:03:10bertrikI still don't really get the low-voltage / sd-card problem by the way, AFAIK sd cards work at 3.3V, not at the internal processor voltage
18:03:36kugelbefore we boosted for microsd access many more cards didn't work
18:03:54saratoga_i always assumed it was the SD controller on the AS chip that had either a problem with lower voltage or a problem with switching voltages (perhaps it ends up in some undefined state occasionally on voltage change)
18:04:53FlynDicewe're using 3.0 v for the sdcard voltage now which matches the of
18:05:06saratoga_i wonder if its worth getting an m200v4 and hooking up jtag to it to see what clocks the OF is using
18:05:11saratoga_does anyone have one of those?
18:05:23saratoga_iirc it had widely spaced jtag pins that could be readily used
18:05:24bertrikdomonoky has one
18:05:55bertrik(an m200v4 I mean, not sure about any jtag adapter)
18:06:09saratoga_serial to jtag adapters are a couple dollars IIRC
18:06:24saratoga_though maybe just reverse engineering the OF more is easier
18:06:35*domonoky could send the m200v4 to someone todo this...
18:07:10kugelsaratoga: the current problem is the switching probably, but number of non working cards was way higher when we accessed them while being at lower voltage (that wasn't a switching problem)
18:07:40saratoga_i still want to know why we can't clock the AMS memory controller at 2x PCLK

I found that weird because you usually get a default picture showing a question mark for missing art - why should that not work if those would have to be used for all albums?

21:58:26Unhelpfulamiconn: i'm not sure you'd need to invert the division loop "test" at all if you invert the numerator instead of the divisor... but i'm also not certain that it solves the problem of being able to shift out bits that are needed. i already have a framework for emulating adds with carry etc in C, i'll give it a try when i get a chance.

22:38:43B4gderRockbox talk at Fosdem 2010 more or less decided now
22:44:29AlexPIn the linux section? :P
22:44:48B4gderhahaha
22:45:32B4gderthere's an "embedded dev room" for which I'm aiming
22:45:44AlexPSeems more reasonable :)
22:46:16B4gderI think its already more or less accepted
22:46:24AlexPcool
22:46:35B4gder"already" being fosdem time schedule, I would otherwise say its rather late
22:46:45AlexPyeah, it is in Feb right?
22:46:51B4gderyes, feb 6-7

22:56:00shaika-dzarihello everyone
22:56:31shaika-dzariCan I ask a question related to rockbox utility and sansa e200v2 ?
22:56:33pixelmaB4gder: while you are here, could you check why the 5/6GB H10 links on the daily manuals page link to the 20GB H10 manual? As far as I remember those are separate manuals due to the different screen resolution, haven't checked if the former still builds though yet

23:00:55pixelmashaika-dzari: don't ask to ask...
23:01:37shaika-dzariok, I want to install rockbox on my sansa e200v2 with rockbox utility 1.2.3
23:02:01AlexPI don't think rbutil release versions supports the v2
23:02:47AlexPalthough I could well be wrong :)
23:02:49shaika-dzariWith 1.2.3 I can select sansa e200v2 series (Unstable)
23:02:54AlexPah, OK
23:03:10AlexPThen I was wrong :)
23:03:11shaika-dzariThis is the first time I try to install rockbox
23:03:57shaika-dzariSo, if I understand correctly, I should install the bootloader and rockbox in installation Tab.
23:04:47AlexPyep
23:05:12pixelmaB4gder: the small H10 manual still builds locally
23:05:17shaika-dzari>Ok, I select default bootlaoder and current build of rockbox and it should be fine?
23:05:23AlexPyep
23:05:37shaika-dzariOk, I try right now
23:06:17Unhelpfulamiconn: i've gotten another cycle off of the large-numerator handling. i think that what i'm doing now is likely as cheap as inverting the numerator, if that would work... it costs only 4c from the small-numerator case, one to unconditionally save the old numerator (with flag set), one to shift the numerator right if that save has a negative result, one for an asr one on the stored numerator, and one for a bmi to the fixup code. the same
23:06:17Unhelpful asr 1 also puts the bit that was lost into C, and the fixup can avoid other flag-setting ops until it needs that bit.
23:06:48shaika-dzarihe, 300 mo free space should be enought for rockbox?
23:07:03AlexPloads
23:07:28AlexPRockbox is about 10/15 MB if you include all the fonts etc., less without
23:07:40Unhelpfulhere's the code as it is now: http://paste.pocoo.org/show/163805/
23:07:45AlexPIncidently, install the fonts too :)
23:12:27shaika-dzaricool, installation done.
23:12:52shaika-dzariI'll umount my player and try to boot.
23:12:58B4gderpixelma: I don't even understand how the builds are done these days... :-O
23:14:40Unhelpfulit probably still loses on beast. the shifted operand in the divide loop causes a 1c interlock, and i'm not certain but it may do so even if the subcc is skipped... so we're as slow as the libgcc divider inside the main loop, and have extra fixup.
23:16:33shaika-dzariwow, work great! Thanks AlexP!
23:16:43AlexPshaika-dzari: No worries, enjoy :)

23:46:27AlexPWhy do all the lang files have the same line "# $Id: portugues.lang 23888 2009-12-07 13:53:55Z zagor $" with everything identical except the language name?
23:52:52bluebrot1erperhaps all of them were changed in r23888?
23:53:25bluebrot1eror someone copied the string and adjusted the filename and svn:keywords isn't set.
23:55:00AlexPbluebrot1er: I'm assuming the latter, as lang files are updated periodically
23:55:18AlexPSo for a new one, I'll set keywords and delete that line
23:55:20 Nick bluebrot1er is now known as bluebrother (n=dom@f053154253.adsl.alicedsl.de)
23:55:24AlexPI guess :)
23:55:34*bluebrother is about to check it
23:55:40AlexPcheers :)
23:55:59bluebrotherall lang files show r24208 as last changed revision here.
23:56:37AlexPWhich is current svn
23:57:00AlexPWhich didn't touch lang files
23:57:08bluebrotherthe last change is "Corrected ondio language wildcards." Seems like a good commit to touch all lang files
23:57:31AlexPah, good point
23:57:53AlexPI'm looking at the slovak.lang on flyspray
23:58:11AlexPWhich looks to have been based on a previous one
23:58:29AlexPSo for that, I delete that line from the file and set keywords
23:58:33bluebrotherhmm, svn info returns the latest revision, not the last revision that touched the file. Good to know.
23:58:36AlexPbluebrother: What rev was that?
23:58:49bluebrotherr23888
23:58:58AlexPSo that makes sense then :)
