00:10:11MrKeunerhi, there.
00:10:23MrKeunerWHat files should I update when upgrading rockbox?
00:10:39scorchejust unzip the folder to the root
00:10:48MrKeunerI do not really want to do all the settings again
00:10:53scorcheyou wont
00:10:54DerPapstdionoea: ping
00:11:02dionoeapong
00:11:03scorcheif you want to make sure you wont, save teh settings to a file
00:11:20MrKeunerscorche: also there are wps files etc
00:11:28 Quit ShadowSponge (Read error: 104 (Connection reset by peer))
00:11:44DerPapstdionoea: i have made a small patch for reversi to optimize it's usage (mostly on 3G) iPods
00:11:49MrKeunercan't I just copy rockbox.ipod
00:11:50DerPapstdionoea: http://pastebin.eu/pastebin.php?show=17
00:11:57*amiconn guesses the function caluclates ln2 of a fraction

00:13:23MrKeunerso no way. I have to recopy the wps and related files and the settings files?
00:13:30saratogalinuxstb: I'm here
00:13:37bluebrotherbut since the settings are stored in a file (/.rockbox/config.cfg) you can simply store that somewhere else
00:13:49DerPapstMrKeuner: you're settings and wpses won't get overwritten
00:13:55scorcheas we said, they wont....yeah
00:13:59bluebrotherwhy don't you just extract the new build over the old folder and overwrite all files?
00:14:09bluebrotherthat's the way you usually are intended to update.
00:14:31MrKeunerI didn't know that unzip did not remove all the contents in a folder and unzip on them
00:14:35MrKeunerOK I'll do that
00:14:39MrKeunerthanks
00:14:40dionoeaDerPapst: why is that 3G specific ?
00:15:09DerPapstdionoea: well it's not entirely 3G specific ;)
00:15:19linuxstbsaratoga: I've been doing some more asf work today - I've more or less decided to abandon libasf itself, and write a simple parser instead. libasf works by reading everything into memory structures first, and then parsing them. Whereas, it's better for Rockbox to parse as it goes along.
00:15:24dionoeashouldn't you just change the ifdef to "all ipods" ?
00:15:35DerPapstdionoea: it makes the layout a bit more consistent to all iPods
00:15:39saratogalinuxstb: that sounds like a lot work
00:15:50linuxstbsaratoga: But I've got the basics of a "get_metadata" function working already.
00:15:58saratogawow
00:16:04DerPapstdionoea: that isn't nessesary imo.
00:16:16linuxstbsaratoga: Not really, asf is in fact a very simple format, and there are lots of objects we can simply ignore and skip.
00:16:22dionoeawhy are you changing it only for the 3G then ? (the wrap mode)
00:16:35saratogaI'm working on integerizing what you gave me
00:16:42saratogahow much of that is likely to change?
00:16:46DerPapstdionoea: the settings are ok for all other iPods except 3G that's why i limited to 3G only
00:17:05linuxstbsaratoga: You should assume all the asf stuff will change - best if you just stick to the wma decoder itself.
00:17:06dionoeaah ok ... if you say so :)
00:17:11dionoeaDerPapst: i'll apply the patch
00:17:25DerPapstdionoea: but you can change that to all iPods. don't make a big difference to me :)
00:17:32saratogawhat about the parts of the decoder that touch libasf?
00:17:34*dionoea needs a clean rockbox checkout
00:17:35saratogastuff like wma_decode_init()
00:17:36DerPapstdionoea: thanks ;)
00:17:54saratogacan I assume you'll still be passing in the same arguments?
00:17:59linuxstbsaratoga: Well, that's trivial to change.
00:18:12linuxstbI'll need to give you that information, so yes.
00:18:29linuxstbI'll probably keep that same wfx struct.
00:18:31saratogamostly i'm trying to sync the stuff I had with the older version of wmadec.c
00:18:40saratogathere was a fair amount of drift

00:21:49DerPapstdionoea: the 3G iPods has an entirely different button layout compared to all the other iPods. so one can't really use rew, menu, play, fwd as left, up, right, down.
00:22:00DerPapstthanks :)
00:22:41dionoeaI should be the one thanking you :) the keymap was horrible on my ipod too
00:22:50saratogalinuxstb: is there some linux app that people use to reformat the layout of code?
00:23:04linuxstbProbably, but I don't know it...

00:41:47dionoea:)
00:41:51dionoeashould be fixed
00:42:03amiconnwow!! :D
00:42:27amiconnThe mini g1 boosts and unboosts playing aac, without hanging!
00:42:30*bluebrother awaits some good news from amiconn
00:42:35bluebrothercool :)
00:42:49amiconnSo now this needs testing on other PP5020s
00:43:02dionoeaGood night ppl (/me can't wait to read tomorrow's commits from amiconn)
00:43:12amiconnIt's a bit hackish atm
00:43:30amiconn(I'll redefine the CPU for the targets which are actually PP5022)
00:44:04amiconnPart #2 also isn't done yet (saving more power), I just applied part #1 (the clock magic for PP5020, and relock wait for PP5022)
00:44:15amiconnI'll test the relock thing next
00:44:26amiconnlinuxstb?
00:44:36dionoeawould part 1 save power ? or is it stability issues only ?
00:44:43DerPapstdionoea: good night :D
00:44:54 Quit \sic (Read error: 110 (Connection timed out))
00:44:58amiconnIt will save power by the fact that cpu scaling works now
00:45:36amiconnCPU scalin gis disabled in svn for H10, and I had to disable it for mini g1 locally to make it even boot
00:46:18dionoeaah ok.
00:46:27amiconnThe relock thing might also save a bit of powe
00:46:28amiconnr
00:46:48bluebrotherI can test on mini 2G if that helps ...
00:46:59amiconnThat's 5022, and I have one myself
00:47:07amiconnI would be most interested in H10 testers
00:47:21bluebrotheryeah −− just in case you're interested in more testers.
00:49:09amiconnlinuxstb: I even removed the TIMER kludge for PP5020, and it works _stable_
00:49:14*DerPapst could only donnate a PP5002 and a PP5022C
00:49:51DerPapstamiconn: nice work :)
00:50:02amiconnI guess that we can even run at 80MHz boosted with proper voltage handling
00:50:18amiconn(stable)
00:51:26amiconnHmm, I even have a suspicion what the PLL status magic actually does...
00:51:59*amiconn added PLL_CONTROL and PLL_STATUS display to 'view i/o ports'
00:52:59amiconnThe thing boosts/unboosts roughly once per second. No hang so far. Will listen to the whole album...

01:12:35amiconnHmmm :/
01:12:50amiconnHalf an hour ago I would have had one
01:13:00DerPapst?!
01:13:13jhMikeSamiconn: any change in the behavior of core locking? did you happen to pick up anything about the memory controller such as defining noncacheable areas or controlling what get flushed?
01:13:24amiconnNow I'm in the process of converting the appropriate targets to use a PP5022 define, and my tree probably doesn't compile
01:13:56amiconnjhMikeS: I didn't look at the core locking at all anymore
01:14:11amiconnI just want to solve the clock & power issues
01:14:49amiconnpcm-pp.c is strange :\
01:14:50jhMikeSby the TIMER kludge you were speaking of the |= when scaling?
01:14:55amiconnyes
01:15:10amiconnMy album is still playing btw
01:15:12*jhMikeS is redoing that a bit right now
01:15:14linuxstbWill you be treating the PP5021/22 the same?
01:15:22amiconnThere is no 5021
01:15:32amiconnThere is only a PP5022B and a PP5022C
01:15:55amiconnThe case print might be different, but that's not significant for the code
01:16:45amiconnjhMikeS: Didn't you do some work in pcm-pp.c?
01:16:57amiconnI don't understand the ifdefing
01:17:21jhMikeSI'm redoing the pcm level API a bit so that it is well locked again the interrupts handler for all players and the states are proper
01:17:47jhMikeSwhich #ifdefing in particular
01:17:47amiconnI'm wondering of about the ifdef above/around the asm blob
01:18:00amiconnDoes that mean Sansa uses the C version?
01:18:18amiconnI would think the C version is only there for reference
01:18:32jhMikeSno, sansa uses the asm
01:18:49jhMikeSsansa uses 16 bit IIS mode and the iPods are still using 32-bit
01:19:06amiconnOK, strange thing is:
01:19:14amiconnline 55: #ifdef CPU_PP
01:19:34amiconnline 157: #else /* !(CONFIG_CPU == PP5020 || CONFIG_CPU == PP5002) */
01:19:51amiconn(1) Shouldn't the commect read /* !CPU_PP */
01:20:04amiconn(2) Why not just simply #if 1 / #ese
01:20:09amiconn*#else
01:20:53jhMikeSI don't know. the comment just hasn't been updated?
01:21:55jhMikeSthe C version of the fiq handler doesn't work anyway because of 1) gcc bugs 2) FIFO_FREE_COUNT is wrong. There's a count field for each of TX and RX fifos.
01:22:56jhMikeSMy changes will straigten that all out though
01:23:06*amiconn introduced an new CPU #define: CPU_PP502x

02:02:47webguest35it just charges on rockbox mode

02:03:22crashmatrixand the original fw will magically load
02:03:33peturIs there anybody here that knows the fat code?
02:03:38webguest35thanks a lot , it worked :)
02:03:41linuxstbWhich ipod do you have?
02:04:32jhMikeSamiconn: It supposedly worked but the clocking setup was wrong and taking its toll on performance in general and partly causing lcd issues
02:04:53linuxstbamiconn: It's boosting/unboosting frequently (boost ratio about 68%), and still running. So looking good. But in the past, when Rockbox has been running well, it can take a couple of hours for it to freeze.
02:04:54*petur wonders if there's a reason update_short_entry() pokes around with char/long pointers iso mapping a fat_direntry on it...
02:05:03amiconnIs the PP5024 again different in regard of clock setup?
02:05:28amiconnlinuxstb: On the mini g1 I have here, it already locked up at boot in 50% of the cases
02:05:39jhMikeSI think so or at least the sansa is setup differently
02:05:50amiconnIn the other cases I was able to browse a bit. No chance of playing music
02:06:08linuxstbamiconn: The frequency of lockups seems to be random - some builds seemed to be fine, some locked up at boot.
02:06:34amiconnI will let the mini g1 play with repeat enabled (and charger connected) overnight
02:08:55*amiconn should do this with the mini g2 as well
02:09:03amiconnOnly one can have the charger though

02:58:58Hammer89ah... guess not then ;)
02:59:39Hammer89is it a hardware issue? or will it be possible to make drivers to support a 4gb card? (I'm somewhat ignorant on this)
03:00
03:00:12LloreanI don't think anyone knows for certain whether or not it will be possible yet.

04:22:32TeleosusHello all, anyone willing to answer a quick question about future rockbox developments?
04:22:59LloreanTeleosus: It's somewhat unlikely anyone can answer a question about the future.
04:25:01TeleosusWell, I just bought an E280 and after quite a bit of web research it seems that the possiblity of rockbox helping in the ares of SDHC support is waning, anyone else feel the same?
04:25:28TeleosusNot that I would know how to do it
04:25:32JdGordonI dont belive any of the devs own a sdhc card, so we have no way of knowing if it works
04:26:23Teleosusnot that I would know anything about doing it....

04:27:48LloreanNico_P: Ah
04:27:54Nico_PI've been making a bit of progress just now
04:28:02LloreanIs the SVN holding work on a stand alone, or is it a modified Rockbox?
04:28:13Nico_Pit's standalone
04:28:28Teleosushad network problems , sorry didI miss something?
04:29:05LloreanI'll check it out soon then.
04:29:19LloreanTeleosus: Nothing really. Generally speaking, nothing happens unless people who own the hardware are interested in it
04:29:44Nico_PLlorean: if you see Bagder around, could you ask him about hosting a parallel SVN or git on the rockbox server for this kind of work ?
04:30:10LloreanNico_P: Will do, but I think it's already been suggested.
04:30:19LloreanGit would certainly help with the SoC stuff
04:30:21TeleosusWell all I have really been able to deduce is that noone is really sure if it will be possible without a hardware update
04:30:23Nico_Pby me :)
04:30:31Nico_Por maybe someone else suggested it too
04:30:33LloreanI think others may have mentioned it too. ;)
04:30:41Nico_Pok
04:30:46LloreanI seem to recall it's listed on the pro-git wiki page, though I can't remember the page's name

05:20:39webguest03hey
05:20:43webguest03i have no clue what to do
05:20:51webguest03to install rockbox on my ipod video 30gb
05:22:30krazykitread the manual
05:22:51webguest03k found it
05:22:54webguest03i was looking for it
05:22:58webguest03in the files
05:23:02webguest03but its actually in the site
05:23:11BossierI'll go ahead then, in line 893 or so of screens.c the #ifdef HAVE_LCD_BITMAP was changed from the if else with lcd_setmargins to a simple if else with statusbar_height, the thing is immediately after that statusbar_height is set to 0. I'm thinking that statusbar_height = 0 part should have come before the #ifdef so it didn't negate it
05:23:38 Quit webguest03 (Client Quit)
05:24:14BossierReason I ask is I was just syncing my copy of the scrolling margins patch and it concerns that, I went ahead and did the change on my own code and am noticing no ill effects
05:24:49LloreanBossier: I don't quite see your question
05:25:54LloreanIf HAVE_LCD_BITMAP is not defined, statusbar_height is always 0
05:26:23LloreanIf it IS defined, then if global_settings.statusbar is true, the height is set to STATUSBAR_HEIGHT, otherwise it is set to 0
05:26:48Bossieryes but immediately after that statusbar_height was set to 0, would that not negate the ifdef, I was thinking setting it to 0 should come before checking for havelcdbitmap, not before
05:26:52 Quit AdmiralJ ("Quitting")
05:27:08Bossierafter not before i mean
05:27:15LloreanI think you're reading it wrong
05:27:18Bossierbefore not after I mean, long day
05:27:30LloreanIf the define is true, it reads "else set it to 0" not simply "set it to 0"
05:28:06LloreanThat line is contained within the if-else statement if the define is true, it doesn't negate the setting.
05:28:09BossierI don't have else set it to 0 in my define, I have it set to 0 outside the define immediately after it

05:28:47LloreanBut the else is there if the define is true
05:28:59BossierSo set it to 0 should have been in the else part of the define?
05:29:01Lloreanso you get "else set it to 0", if the define is true
05:29:03LloreanNO
05:29:19LloreanIf the define is true, remove the #ifdef and the #endif lines entirely, and pretend like they were never there
05:29:33LloreanIf you do that, you'll see that you get a full if-else
05:29:47LloreanJust delete those two lines, the ones starting with #, to see what it would be like if the define is true
05:30:21BossierI don't think you're getting what I'm saying, in my define I have an empty else statement
05:30:25LloreanYes
05:30:26LloreanI know
05:30:28LloreanI'm looking at the file
05:30:33LloreanDELETE the lines starting with #
05:30:36LloreanJust do that for me please
05:30:44LloreanYou'll notice that with them gone, the else statement isn't empty any more, is it?
05:30:53LloreanYou have to remove the whole line, not just replace it with a blank line.
05:31:51BossierI understand what you're saying, what I did with moving statusbar_height = 0 to above the ifdef and deleting the empty else is working for me, I was gonna go with that, but as you advise I'll do it your way
05:32:07LloreanDo you understand how preprocessor directives work?
05:32:16Bossieryes
05:32:31LloreanThen you know that if the define is true, what's handed to the C compiler doesn't contain either of the # lines
05:32:39LloreanInstead you get a fully functional, proper if-else statement
05:32:49LloreanWith the statusbar_height = 0; line being included in the else part of it
05:33:05LloreanIf you don't believe me, run it through a preprocessor with the proper define set and check the output.
05:33:55Bossiergotcha, I just don't like the way the ordering looks, I do know what you are saying, just a cosmetic thing really
05:34:17LloreanWell earlier you were talking about it negating the statement.
05:34:31LloreanJust wanted to make it clear that it actually doesn't, it's just a bit unclear what is happening there.
05:34:44Bossierbrain fart, I sometimes also forget that this is all in C and I can't get my brain out of object oriented mode
05:34:58LloreanRemoving the "else" entirely, and moving the =0 before the #ifdef would create functionally equivalent code, but it would require one extra assignment in cases where there is a statusbar
05:35:23Bossierthanks, feel kinda stupid now, but I'm glad that's cleared up
05:35:40LloreanOh, it's definitely not 100% clear what's going on there.
05:35:54LloreanI'd never seen it before and had to stare at it a bit to put things in order in my head
05:35:57Bossierjust so you know in all honesty I haven't coded in 10 years, coding is a young mans game
05:37:18LloreanAnyway, it works, and I would *guess* that it's like that for a slight increase in efficiency. Though it's entirely possible that it's like that because someone simply didn't think of doing it the other way, you never can tell.
05:38:38Bossierthanks again, btw, I'm tdtooke, on irc i'm always bossier and i'm too lazy to change nicks, gotta run now. on a personal note you're much nicer in person that you seem at times in the forums
05:38:57Bossierdont' take that the wrong way
05:39:06LloreanYeah, I'm actually even nicer in person-person, as the Devcon West guys can attest.
05:39:23LloreanEnforcing the rules at a level where people know you're serious never makes a person look nice, sadly.

07:37:13Ic0neYeah
07:37:39Ic0nebut, for all its speed, the ''plasma'' extension his speedy so...
07:40:30aliaskIt's because the gigabeat has a much faster CPU than all the other DAPs that rockbox supports
07:41:12aliaskThere is no way to slow down plasma (that I know of), but I don't think it's very important...

10:30:56cropI have two questions about the code. 1) Shouldn't the RB api field be moved from the game to the strategy struct? Since the game should be API neutral and only the strategy needs the API (for rand I think)
10:31:50cropAnd 2) Shouldn't the threshold consts (for the AI) be moved from the general .h to a specific .h (if there is one)?
10:31:58dionoeacrop: well the game struct is the only one that were sure to have everywhere (like if we ever need the rb struct in reversi-game.c)
10:32:23dionoeathe CHAOS consts ?
10:32:44dionoeas/were/we're/
10:33:23scorcheBagder: around?....i havent seen b4gder yet =P
10:34:44cropdionoea: couldn't it be made a globar var that's declared in strategy.h? I just think that it belongs more to strategy than to the game itself. But making it a global isn't nice either. Hmm...
10:35:17dionoeai could declare it as extern in the .c files which need it
10:35:30dionoeabut then i doubt that it really matters :)
10:35:37dionoeaas long as it works
10:35:51cropdionoea: and yes, I mean the CHAOS consts
10:36:03dionoeathose will be used in multiple strategies
10:36:19dionoeawhich is why i put them in the strategy.h header
10:36:39dionoeabut i haven't commited those yet
10:36:46dionoea(since i didn't finish porting them)
10:36:47cropdionoea: yes, that's what I meant: declare it as an extern in strategy.h which is included by all strategy-*.c
10:37:14dionoeayeah, i might do that
10:37:16cropdionoea: ah, ok then
10:37:32crop(reg CHAOS)

10:52:44pondlifeHmm, even worse than me!
10:53:05pondlifeSomething changed for the worse in the past few weeks.
10:53:18peturindeed
10:53:28pondlifeGDB doesn't even give a useful backtrace.
10:53:52pondlifeGuess I'll try binary-chopping into past revisions...
10:54:45peturmay be a simple issue
10:55:07JdGordonwhats the best way to diff two bin files?
10:55:46petursomething else that's worrying me: I've had stkov in power when attaching usb this weekend (not reproducable anymore, it went away), and somebody reported stkov in main in the tracker
10:56:07JdGordonon which target?
10:56:07peturJdGordon: in dos: fc /b
10:56:13dionoeacrop: the struct is defined as const, not the pointer to the current strategy struct which is defined in reversi-gui.c
10:56:13JdGordonpetur: linux...
10:56:37dionoeaand about the supervised mode, sure, everything is possible. You only need to add the code that goes with it :)
10:57:08 Part kaaloo
10:57:41cropdionoea: I mean this: const game_strategy_t *white_strategy; Doesn't it mean that white_strategy is a const pointer?
10:58:09cropOr a pointer to a const struct?
10:58:20Zagorpetur: what goes wrong with your patch? boken filesys, early return or something else?
10:58:40cropAh, probably the latter
10:59:04dionoeayup
10:59:42dionoeaelse i would never be able to change that value
10:59:48dionoea(even during init)
10:59:49amiconnpondlife: Is this stil fs #7245?
11:00
11:00:01peturZagor: it doesn't fix the issue at all. chkdsk complains that the . and/or .. entries are wrong. The .. entry should obviously be changed to point to the new parent but somehow my fix doesn't do that (ie it still complains)
11:01:04Zagorperhaps it's time to bring firmware/test/fat/ back to life
11:01:21cropdionoea: another thing (sorry for disturbing you): wouldn't it be better to initialise the game so that one party is a robot and the other is the user at the start? Or will it be a config that can be saved (not implemented now but later)?
11:02:01dionoeayeah, it would be better to initialise black as human and white as AI and save config changes :)
11:02:15dionoeapatches welcome
11:02:20pondlifeamiconn: That still happens, but this is a different segfault
11:02:28dionoea(I'm at work so i can't really code on rockbox now)
11:02:44pondlifeI shall FS it, but wanted to see if it was just me

11:08:03dionoeaI also need to fix a bug in the simple-ai (or the ai calling code) which makes it enter an infinite loop sometimes when playing simple vs naive or simple vs simple.
11:08:23cropdionoea: and what about your commit comment about not being able to beat the simple AI?
11:08:37dionoeawell i only tried once before doing that commit :)
11:09:03dionoeain fact it's really easy to get the four corner stones against any of those AIs
11:09:15dionoeaand once you've got the corners you've basicaly won
11:09:30dionoeawhich won't be easy to do with the next AI
11:09:57cropdionoea: :-) BTW: I've read that reversi is a game that can be played well by computers. I.e. much better that chess. So if a good AI will be implemented we'll have no chance!
11:10:31cropthat -> than
11:10:35dionoeaI'm porting the AIs from hinversi. I don't know if they're considered as good ... but i hope that they are :)
11:10:42dionoeaElse i'll have to look for others
11:11:37dionoeaOn a fast computer i believe that you can test all possible moves all the way to the end ... i doubt that it's possible on a DAP though
11:11:52pondlifeamiconn: I've put a note and my config on FS #7245... maybe you could try to reproduce it in linux-x86 and see if you get anything helpful?

12:02:12GodEaterNico_P: I managed to try out what we were discussing on Friday, and it seemed to work okay - I ended up with another branch in my "clean" git-svn repo of rockbox
12:03:01Nico_Pcan you remind me what it was ?
12:03:32GodEatergetting a branch from my public repository into your rockbox git-svn tree
12:03:49GodEaterand being able to then merge it in and commit,
12:03:54GodEateror choosing to ignore it
12:04:03GodEaterI believe that's what you were asking me to do ? :)
12:04:16Nico_Poh yes
12:04:26Nico_PI'll check that out
12:04:35GodEaterthere *may* be issues with binary files though
12:04:46GodEaterI did have a brief hiccup with one of the sokoban bmps
12:04:52GodEaterbut it went away again
12:05:02GodEaterso it might just have been a PEBKAC issue
12:06:04Nico_P:)
12:07:02GodEaterI get those a lot :)
12:08:24Gabrilhi, are there any news about mpegplayer and native ipod-video-hardware support?
12:08:32markunGabril: no news
12:11:38pontapehi all, i wanna ask if rockbox runs stable on ipod 5.5g 80gig ?!
12:12:18GodEaterpontape: stable enough
12:12:22GodEaterI use it daily
12:12:42pontapeah ok fine
12:13:09GodEaterjust bear in mind the usual ipod caveats
12:13:34GodEater1) lower battery life than original firmware, and 2) the processor sucks so don't go mad with the DSP effects and expect silky smooth playback
12:14:47pontapehehe, well i am an absolutly rockbox newbie, first i have to get it installed somehow :>
12:15:02GodEaterpontape: go to our wiki and the RockboxUtility page
12:15:07pontapei want it mainly for playing my .acc's
12:15:07GodEaterthat makes it pretty easy
12:15:15pontapeaac
12:16:39pontapeok i will
12:17:18pontapeis the installtion possible without running linux ?!
12:17:29Gabrilyes, work's fine with windows
12:18:00Gabriljust read the howto - and within 10 minutes you have your rockbox up and running

12:30:45JdGordonseen the svn log?
12:30:49Nico_PI've seen your changes and I tested a bit
12:31:08Nico_Poh another change :)
12:31:10JdGordonthere is a bug in the bufread() when the data wraps
12:31:32Nico_Pthere was one in bufclose that I fixed
12:31:46JdGordonmy debuggin pretty much confirms its there and not in the actual buffering
12:31:46pondlifeYour svn? I'm still unable to get to it... :(
12:32:01Nico_Pout of my 4 files, the 2 last were wrong and now it's only the third
12:32:06Nico_Pthe third is the one that wraps
12:32:41JdGordonodd... my test files all are fine except the one that wraps
12:32:52JdGordonI was gonna fix it now but heading out for a while
12:33:01Nico_Pok, maybe I'll find it :)

12:36:14pondlifeYes, created by this command, in a /mob dir.
12:36:31Nico_Pwhat if you wipe everything clean and start again ?
12:36:43pondlifeThe same
12:36:55pondlifeIt recreates /mob/.svn/...

12:38:46DerPapstalso on cygwin or linux?
12:38:49pondlifeDid you have to do any kind of user/login config?

12:39:19Nico_Pyou're using svn in cygwin ?
12:39:28DerPapstyes.

12:39:56pondlifeBut svn log works ok
12:39:58Nico_Pyes, you're supposed to run st on a working copy, not an URL
12:40:22Nico_Ptry info instead
12:40:42pondlifeYes, that seems ok
12:40:59Nico_Pare you suree verything's right with the file permissions ?
12:41:02pondlifeSo why no checkout..?
12:41:47pondlifeWell, I have my Rockbox working copy in D:\Cygwin\home\Steve\rockbox... and I just made a D:\Cygwin\home\Steve\jdgordon to work in.
12:41:53DerPapstafaik there are no file permissions in cygwin/windows
12:42:16Nico_Phmm very strange
12:42:35Nico_Phave you tried a windows svn client like tortoisesvn ?

13:00:58GodEaterpondline: same way you couldn't call a file "D:.txt"
13:01:03idnaroh, another fun one
13:01:09idnarif you had a CDROM driver loaded, called "CDROM"

13:02:28Nico_Ppondlife, DerPapst: you just feed the app a series of files as arguments. It will buffer them then unbuffer them and hopefully the unbuffered files will be exactly identical to the originals

14:14:22Nico_Ppondlife: what I was thinking is maybe have the internal buffer of a handle be a ring buffer for big files
14:15:05Nico_Pbecause we'll want to have other handles there too and we don't really want them to move
14:15:22pondlifeThat will work, but wouldn't you need to have a guard buffer per file... rather than just one per buffer?
14:15:47Nico_Pwell... what exactly is the guard buffer for ?
14:16:00pondlifeAh, you should look into that!!
14:16:31pondlifeI'm not totally sure, but the MAS has certain requirements - amiconn should be able to help.
14:17:38pondlifeIIRC you need to be able to guarantee to feed complete chunks (contiguous in memory)..
14:18:04pondlifeBut I might have got horribly confused (again).
14:19:08LinusNthe guard buffer is a MAD thing
14:19:18pondlifeMAD or MAS or DMA?
14:19:29LinusNMAD as in libmad
14:19:49pondlifeSo not a MASCODEC requirement at all?
14:19:53LinusNnope
14:20:05*pondlife *is* horribly confused
14:20:37LinusNunless the guard buffer is 30 bytes long
14:21:43LinusNwhich guard buffer are we talking about here?
14:21:48Nico_Pbut what is it used for exactly ?
14:22:28Nico_Pit's not a requirement for every ring buffer ?
14:23:35LinusNare you talking about the guard buffer mentioned in RockboxMemoryLayout?

14:24:49Nico_Pyes

14:25:52pondlife(But I thought it was also used for MAS somewhere, seems not)
14:25:54LinusNi have no idea what that might be
14:26:09LinusNthe MAS code doesn't use playback.c
14:26:14pondlifeI know
14:26:28pondlifeBut I thought it was referred to somewhere else too.
14:27:15LinusNi wrote the MAS playback code, and i have never heard of the need for a "guard buffer" there
14:27:16pondlifeIt's basically a buffer to ensure a codec's request can be fulfulled with a contiguous block
14:27:46pondlifeSee playback.c - codec_request_buffer_callback()#
14:28:19LinusNok, i see now
14:28:32LinusNthere is nothing of the kind in the MAS playback code
14:28:34preglowcodecs can't access a circular buffer, the guard buffer is just to make sure all data can be access linearly

14:28:58LinusNmarkun: is it a wiki topic?
14:29:03*pondlife is sorry he mentioned MAS at all... ;)

14:31:31markunLinusN: thanks
14:31:41Nico_Phow does decoding work ? the codec has reads the buffer directly or is there some copying invloved ?
14:31:49 Quit cyberstream ()
14:34:02preglowNico_P: yes, that's how it's used, afaik
14:36:39Nico_Ppreglow: and the codec accesses the buffer directly ? that's why it needs the data to be linear ?
14:36:59 Quit z35 (SendQ exceeded)
14:39:40*linuxstb now has his own asf parser working (outside Rockbox)
14:41:03linuxstbNico_P: Yes, most (if not all) codecs use the "request_buffer" API to get a pointer to some compressed audio that needs to be decoded. This generally needs to be one compressed frame of audio, otherwise the codec would need to continually range-check on the size of the input buffer.
14:42:32Nico_Pwhat size is a frame ?
14:42:37Nico_Pis it always 32K ?
14:42:42GodEaterI would imagnie that depends on the codec
14:42:43linuxstb−−> <−− this big...
14:42:51Nico_Pok :)
14:42:57linuxstbIt's always less than 32KB - which is why the guard buffer is that size.
14:43:20linuxstbOr at least, if the frames are bigger than 32KB, (e.g. APE) the codec handles them in < 32KB chunks.
14:43:53Nico_Pok so for files bigger than the buffer I'll need to have a guad buffer too
14:44:03*Nico_P needs to do some thinking
14:44:12amiconnShouldn't the new api allow to select the guard buffer size from the track loader, to support non-streamable formats?
14:45:13Nico_Pamiconn: you mean specify the guard buffer size when requesting that a file be buffered ?
14:45:16linuxstbIt at least needs to handle those files - IIRC, varying the guard buffer size was just one possible solution.
14:47:19Nico_Pwhat if I define a 32 KB buffer and copy the data to it for the codec to decode ?
14:47:59amiconnMany non-streamable codecs (the mod formats) need the whole file as a single contiguous block
14:48:22Nico_Pah so these can't even wrap... ?
14:48:25linuxstbNico_P: Do you mean for every frame, or only when needed?

14:48:39linuxstbNico_P: Yes.
14:48:50Nico_Plinuxstb: well it would only be when needed
14:48:51 Quit SirFunk (Remote closed the connection)
14:49:27Nico_Pthe thing is I might have something like an "internal" ring buffer
14:49:49Nico_Pso it won't be contiguous with the guard buffer
14:50:41linuxstbAssuming the guard buffer is 32KB, that doesn't seem a problem. But if the idea of variable sized guard buffers is implemented, then it will be.
14:54:37preglowi don't think the guard buffer will be needed for nonstreamable formats
14:54:48preglowi a file doesn't fit without wrapping, don't load it
14:55:10 Quit Arathis ("Bye, bye")
14:55:28preglowit needs to be contiguous before use anyway
14:56:20Nico_Pthat sounds logical to me
14:56:41Nico_Pand that way I only need a 32KB guard buffer, which I can use to store a whole frame if needed
14:57:07dionoeacan files always fit in the buffer ? (can't you have cases when they're bigger than the whole buffer?)
14:57:32Nico_Pdionoea: yes, some files can be bigger than the buffer (think of a long flac file)
14:57:51Nico_P(or a small buffer)
14:57:57dionoeathen you need a way to buffer those even if they don't fit (I never use flac :) )
14:58:14preglowwe already do that
14:58:31preglowmy comment was for codecs that can't be streamed and access files in their entirety
14:58:39Nico_Pyes, and with MoB we also need to guarantee that the associated metadata is also on the buffer too at all times

16:04:55gregjso why the 'skip buffer' option than ?

16:08:40gregjor plugin for amarok, for instance
16:08:56gregjfor the record, it seems to be working okay with yesterday's firmware
16:09:12aliaskThe new amarok (1.4.6) has rockbox'd iPod support
16:09:27linuxstbWhat does that mean?
16:09:52dionoeagood question :)
16:09:53aliaskIt means it can copy file from your computer's collection to your iPod. I don't think it updates the database
16:10:08gregjit updates the apple's database
16:10:10aliaskI think it also filters the files it copies based on Rockbox's supported codecs.
16:10:22gregjI am asking if I can manage playlists n'shaite
16:10:45gregjhey, the first reason I wanted to try rockbox is to go for oggs
16:10:56gregjI have many more files in ogg than mp3, and I don't feel like converting it
16:11:15aliaskThe best way to manage playlists (IMO) is to use the playlist catalogue feature

16:16:40Nico_PI've been working on move_handle and adding a test suite for the linked list
16:16:48gregjis rockbox based on linux, or does it have its own multitasking os
16:16:49gregj?
16:16:58linuxstbIts own.
16:17:09gregjreason I ask, is I would love to have a look on sources, and try to tweak few things here and there
16:17:16gregjbut without understanding the source - this is hard
16:17:37linuxstbIf you have any specific questions, just ask here.
16:18:46gregjatm, none :)
16:18:56bluebrotherI doubt that if Rockbox would be based on linux it would be any easier understanding the sources.
16:18:59gregjother than - where to start, and if there is any sort of 'overview' for newbies
16:19:16bluebrothercheck the "for developers" section in the wiki
16:19:18linuxstbbluebrother: Unless of course you were familiar with the linux kernel...
16:19:25gregjwell, I understand a lot of linux internals, because I kinda work on simmilar stuff (virtualzation, based on linux kernel)

16:24:24gregjmy screen is bit strangly looking
16:24:27gregjbut it last 3 songs!
16:25:00linuxstbgregj: Disabling the cpu clock scaling generally fixes the freezing problems on the G4. You'll need to build Rockbox yourself to do that though.

16:32:46Nico_Pwhat parser ?
16:32:48saratogai got the code you sent me yesterday working in integer
16:32:49linuxstbI now have code which can quite easily be ported to Rockbox - both in apps/metadata/ for the metadata reading, and in the codec itself.
16:33:08linuxstbSo hopefully this evening I'll be able to implement the codec.
16:33:19linuxstbNico_P: An ASF parser
16:33:25linuxstb(for wma)

16:33:52gregjyeah, another thing mpeg playback here was really out of sync (audio against video)

16:34:09preglowlinuxstb: saratoga should be excited about that
16:34:13gregjI don't have nerves enough to lookup the implementation, but I think there is something wrong
16:34:14preglowoh, there he is!
16:34:14saratogaI am
16:34:14preglowhaha
16:34:21linuxstbgregj: Did you change any of the default settings in mpegplayer?
16:34:24gregjit should be that hard to do proper fram edropping
16:34:25saratogano more of this ffmpeg nonsense
16:34:54gregjlinuxstb: I did - I asked it to drop frames, and display fps (which is not working either, it only blinks from time to time)
16:35:13GodEatergregj: did you convert your movie for your ipod as in the wiki ?
16:35:23preglowshop time, brb
16:35:40saratogalinuxstb: could I look at what you have? I'd like to add the latest integer decoder
16:35:42linuxstbgregj: "skip frames" should have been enabled by default. As well as "limit fps"
16:36:01saratogaits somewhat different then the fp version, so i think it makes sense to just use the int version for development of the parser
16:36:28linuxstbIt shouldn't affect me at all. All I'm doing is giving the wma decoder the packets of data to decompress.
16:37:10linuxstbBut give me a moment, I'll upload it. I'll disable some of the debugging info first though.
16:37:45saratogalinuxstb: ok thanks
16:38:10aliasklinuxstb: There was another report earlier today where mpeg playback was really fast, and enabling limit FPS didn't do anything (tested in sim as well, same result)

16:40:02linuxstbsaratoga: It's here - http://www.davechapman.f2s.com/rockbox/asfplay.zip
16:40:48linuxstbsaratoga: If you could replace the wma decoder with the integer one, and give it me back (feel free to add wav writing to it instead of raw output), then I'll try and make a codec out of it this evening (EU time - i.e. starting in about 3-4 hours)
16:42:34Nico_PGodEater: isn't "a pain in the backside" used too ?

17:32:10linuxstbpreglow: saratoga is still using the ffmpeg wma decoder itself, but I've written a new ASF parser, so we don't need to use the ffmpeg one - meaning we can delete a lot more ffmpeg code.

17:33:07JdGordonoh dear :(
17:35:44linuxstbsaratoga: What's the state of your integer decoder? Is it generating accurate output now?

17:38:11saratogadoesn't work on anything less then 32k because I haven't worked out how the LSP stuff is supposed to work
17:38:34pondlifeAny idea how much optimisation is going to be needed yet? Or too early to say?
17:38:34saratogatheres also some code paths in the joint stereo stuff which I haven't tested, mostly for lack of files that use them
17:38:37linuxstbI didn't spot an answer last night - is the 12-bit accuracy a limitation of your integer decoder, or of the ffmpeg codec?
17:39:04saratogalinuxstb: I get agreement with the ffmpeg fp decoder to 12 bits
17:39:15saratogai'm not sure if thats because I'm more accurate or its more accurate
17:39:20saratogabut I get at least 12 bits
17:39:22preglowwell
17:39:26preglowcompared with microsofts decoder?
17:39:32GodEaterJdGordon: hehe - freenode won't let me set my nick as upside down :(

19:47:13linuxstbThe buffer I'm passing to the wma_decode_superframe function.
19:47:27saratogai don't think a superframe can be that large
19:47:46amiconnhrrrrmm
19:47:47gregjcan you point me to a file/web site where I can find info on how to build the thing from sources
19:47:51gregj?
19:48:00saratogai think superframes can be at most 2 or 3 frames, and frames are 2048 samples
19:48:14amiconnThis logarithm function looks like it is floating point, while it takes integer arguments
19:48:28DerPapstsaratoga, linuxstb: nice work :)
19:48:35amiconnAt least a code path leads to something that looks like floating point exceptions
19:48:46DerPapstgregj: there is a guide on rockbox.org.
19:48:48saratogagregj: check the wiki, theres a useful "for developers" section
19:49:00linuxstbsaratoga: I think we should change it to decode one frame at a time, but that's for later.
19:49:05amiconnNow the question is how to test this function....
19:49:14peturgregj: http://www.rockbox.org/twiki/bin/view/Main/DocsIndex#For_Developers
19:49:16DerPapstgregj: and afaik you've aready seen the "For Developers" headline at the index.
19:49:24saratogalinuxstb: doesn't it decode one superframe at a time now?
19:49:29DerPapstthat one for petur ;)
19:49:45amiconnWe have no SIGFPE on target ;\
19:49:48saratogaor do you mean call decode frame directly?
19:50:57linuxstbsaratoga: Yes, I mean decode the small (2048 sample) frames in each iteration of the main loop, rather than the whole superframe - which I've seen can be 10 frames (maybe more)
19:51:19saratogalinuxstb: woah, thats surprising
19:51:31saratogai thought superframes were just a frame + bit resivior
19:51:43saratogasince it doesn't use them if you disable the bit res

21:11:45amiconnBoth are little endian 32 bit, and arm doesn't crash so it's not an alignment issue
21:12:13amiconnsaratoga: Is there some struct mapped to the block?
21:12:21amiconnPerhaps it's a struct padding issue...

21:12:54saratogaamiconn: i haven't looked at that part of the code carefully, but I believe it just has a pointer to the buffer and then reads in bytes and words as it goes

21:46:04c250OwnerAlright, thanks
21:46:07 Quit c250Owner (Client Quit)
21:46:16amiconnAt least I have it running, and it *seems* to work like the OF would do it
21:46:42gregjamiconn: about that PP, so you're not able to register as developer there - and get some sheets, or even sign a document - that will not allow you to release docs, but source - yeah
21:46:42amiconnInterestingly enough, boost ratio on mini g1 and mini g2 is different when playing the same album (!)
21:46:45peturhow do you tell?
21:47:05gregjright, so how can I make sure my plugin do compile ?
21:47:08amiconngregj: You need to sign an NDA (and probably pay $$$)
21:47:33amiconnBut even without the $$$, docs under NDA are mostly useless in the opensource world
21:47:45gregjusualy not
21:48:13amiconnlinuxstb: Playing an ~128kbps AAC album, I get ~60% boost on mini g2, and ~55% boost on mini g1.
21:48:21gregjsee, I work for opensource company (xensource), we have access to docs and stuff from intel and amd, under nda

21:59:50saratogaEnterUserName: theres a simulator for all rockbox targets
21:59:54saratogacheck the wiki
21:59:56SeanInglisDipping into IRC during the day, lots of discussion on frequency scaling. Any good links explaining what this is WRT Rockbox? (allowing the CPU to idle when there's no demand, as opposed to furiously doing nothing?)
21:59:59petursaratoga: I'm not an svn expert but I think: svn revert . -R
22:00
22:00:32saratogapetur: was missing the .
22:00:34preglowamiconn: what handling is there? not a wait-loop, i assume? that would have been a dead giveaway
22:00:49amiconnNo
22:01:06saratogaSeanInglis: theres a wiki page for it somewhere, but yeah, thats the gist of it
22:01:15*linuxstb listens to a wma file on his gigabeat...
22:01:18scorche"Frequency scaling is, in computer architecture, the technique of ramping a processor's frequency so as to achieve performance gains."
22:01:21amiconnregister 0x70000034 needs a frequency-dependent value to be set (in both bit 0..3 and 8..1)
22:01:33preglow\o/
22:01:36amiconnThis was the calculation I was analysing
22:01:37preglowlinuxstb: wooot
22:01:39saratogahmm I did an SVN revert and now linuxstb's patch doesn't compile
22:01:45linuxstbSounds like a bag of shit...
22:01:48EnterUserNameahh thanx saratoga i get it
22:01:51preglowwell, of course it does
22:01:53preglowit's still rockbox
22:01:59scorchehaha
22:02:12saratogaheh looks like linuxstb fixed the problem while i was battleing SVB
22:02:14saratogaSVN
22:02:16amiconnErm, that would be bits 8..11
22:02:36gregjit still doesn't make that plugin
22:02:37gregjshait
22:02:46linuxstbsaratoga: I just removed a lot of the code that didn't belong in wmadeci.c, and restored the original ffmpeg files. It still needs some more cleaning though.
22:02:58linuxstb(my cleaned versions of the ffmpeg files)
22:03:15saratogalinuxstb: can you send me what you have?
22:03:16*amiconn wants a turbo for the G5.5's emergency disk mode :/
22:04:15gregjbtw, how many exactly implementations of mdct, huffman, and friends do yo uguys have there ?
22:04:18gregjI already can see about 4
22:04:19gregj:>
22:04:23*gregj ducks
22:04:26preglowgregj: well, each codec that needs one has its own
22:04:44preglowwouldn't make any sense to put them in the core anyway
22:04:51markungregj: if it's possible to share some code, maybe you can work on that?
22:04:55linuxstbsaratoga: http://www.davechapman.f2s.com/rockbox/wmapatch-v2.diff
22:05:19SeanInglisAh, so effective frequency scaling equates to better battery life, broadly speaking. In the changes you're currently wrestling with, are you at full pelt by default, and tweaking downards when appropriate then? (promise I'll head to the wiki in a tick :-))
22:05:34markungregj: would be interesting to compare the speed of the fft based implementations with the normal imdct ones
22:05:56scorcheSeanInglis: we boost when something that needs it comes up, and turn it back down when it doesnt need it anymore
22:06:17gregjmarkun: yeah, having like one MM library would be indeed cool
22:06:33scorcheon targets that work fine with freqscal that is..
22:06:41linuxstbsaratoga: Running test_codec on the gigabeat gives 272% realtime.
22:06:58saratogahaha
22:06:59markungregj: but maybe they all use different fixed point precisions
22:07:10gregjno idea
22:07:16gregjit is probably too big for me for starters
22:07:20preglowlinuxstb: bitrate?
22:07:27gregjlike i said, I already see some room for improvements in metronome plugin
22:07:27saratogagregj: the wma codec uses an MDCT based on the FFT in 17.15 fixed precision
22:07:42linuxstbpreglow: 80kbps
22:07:43*gregj is musician, 2nd skin after programming
22:07:49preglowwell, that's not too bad
22:07:56saratogai believe MAD uses a similar approach except with 2.30 fixed
22:08:05preglowsaratoga: mad uses no fft for the imdct
22:08:07gregjyou can start by reusing some other code in wma implementation than :)
22:08:12amiconnlinuxstb: Could you please run a test on your color?
22:08:21amiconnamiconn.dyndns.org/pp5020_2.diff">http://amiconn.dyndns.org/pp5020_2.diff
22:08:30preglowsaratoga: also, it uses s3.28 precision :)
22:08:34linuxstbSure. Give me a few minutes to run a test_codec with the wma codec first, then I'll try your patch.
22:08:59gregjamiconn: what it does ?
22:09:06gregjI can give it a go on mine ipod photo
22:09:06SeanInglisscorche: ...and hopefully those that don't *currently* seem "fine" by the looks of it. Bon courage anyway.
22:09:14amiconnIt should avoid the freezes on pp5020 devices
22:09:32amiconn...by handling clock setup more correctly (aka more like the OF does)
22:10:42saratogais the pure MDCT approach preferable to the FFT based one?
22:11:03SeanInglisWorth reading up on by the sound of it. Thanks folks.
22:11:04 Part SeanInglis
22:11:09saratogaalso, I really don't understand why svn revert breaks my source
22:11:17preglowsaratoga: depends how you look at it, from an accuracy viewpoint, it might be
22:11:22linuxstbamiconn: Is it correct that that patch contains fewer files than your first one?
22:11:23saratogais there someone to force it to revert completely?
22:11:28preglowsaratoga: but with an efficient fft the combo will be faster
22:11:33amiconnlinuxstb: Yes. It's against svn...
22:11:35linuxstbsaratoga: rm -fr always works...
22:12:03gregjamiconn: you sure this patch doesn't make it explode in smoke ?
22:12:12gregjamiconn: build finishes, just will give it a shot :)
22:12:21preglowsaratoga: also, a fast direct approach needs factorisation i think is dependent on size, so you don't get a function that can work for multiple sizes
22:12:33preglowdisregard broken english
22:12:38saratogapreglow: that makes sense
22:12:52saratogaand also not very interesting to me then, since I need 6 sizes

22:17:33preglowlinuxstb: i'd say that is pretty decent
22:17:39saratogalinuxstb: thats pretty awesome considering we're doing 64 bit multiplies for everything

22:18:39linuxstbpreglow, saratoga Better than that - 71% realtime (same 80kbps file)
22:19:06preglowsaratoga: why do you use 64x64 multiplies? do you actually need the coef precision?
22:19:07linuxstbIt's still broken on Coldfire though - I blame my asf parser...
22:19:23saratogapreglow: no, but theres no way to do a 32x32->64 one in c
22:19:27saratogaat least that I can think of
22:19:34preglowsaratoga: true, true
22:19:41gregjamiconn: funny it just stops
22:19:47saratogaa few lines of asm should make for a nice speedup

22:20:03gregjdunno
22:20:13preglowsaratoga: though i have observed gcc being clever enough to use a 32x32 asm instruction
22:20:32preglowsaratoga: basically, if it is apparant that the multiplicands are 32 bit, the up-casting to 64 won't matter

22:29:44EnterUserNameoh ok
22:29:51preglowsaratoga2: and i'm fairly intimate with that code, yes
22:29:59gregjamiconn: so my guess is - there is something about those usleeps that apple does afterwards, they must check some flags, and stuff
22:30:09saratoga2preglow: i wanted to try that with my stuff
22:30:23saratoga2seems like all i need to do is change the constants for the decimal point
22:30:23gregjamiconn: usleep is better than for() - in terms of bat usage (probably0
22:30:34saratoga2any reason you can think of thats not going to work?
22:30:47amiconngregj: Checked the source? There is no usleep()

22:32:10preglowfor arm it doesn't matter too much
22:32:11amiconngregj: rockbox has udelay() and sleep(). The former only exists on portalplayer targets, and the latter is useless here, as it works in multiples of timer ticks

22:53:20preglowsaratoga: sure
22:53:24saratogaverses MAD_F_MLX ?
22:53:33scorcheBagder: well, as you likely read, we decided to move away from the wiki based system, and move to a r-t.org type style
22:53:45saratogabasically, which one is the fixed multiply
22:53:57Bagderscorche: yes, that's the only sensible thing

22:54:41Bagderscorche: but still, since Redbreva has a system setup for it, it also makes sense to use his...
22:55:08gregjamiconn: ok, trying it now
22:55:18preglowsaratoga: both are, mad_f_mul does a 32x32 multiply with a 64 bit result in two registers, then adjusts for fixed point format and stores the upper part of the result in a 32 bit register
22:55:37sean__how can i have ipodlinux and rockbox live harmoniously? (5.5)
22:55:43preglowsaratoga: MAD_F_MLX just does a 32x32 multiply and leaves the 64 bit answer unadjusted in two 32 bit variables
22:56:14saratogapreglow: so I want to use mad_f_mul then

22:57:06preglowsaratoga: indeedey, but it depends on your fixed point format, then, this one assumes MAD_F_SCALEBITS is defined to be the number of fractional bits in your fixed point format
22:57:22sean__how can i add rockbox to the iplboot thing?
22:57:27saratogathats saying to do shift right by adding zero?
22:57:35preglowsean__: by going to #ipodlinux and asking
22:57:43sean__fair enough
22:57:58saratogasorry I mean "do a shift, right? by adding 0"
22:58:06 Part sean__ ("Ex-Chat")
22:58:12saratogawhy does it take two constants though?
22:58:17gregjamiconn: bang, crashed after 3mins
22:58:36gregjI will change usleeps to 255,and see, I am really sticking to that theory
22:58:44preglowbecause there are two shifts, namely (hightpart << x) and (lowpart >> (32 - x))
22:58:45scorcheBagder: indeed it does, but the one thing i came up against is if we make his site official, the copyrighted material themes will disappear, and i think that there are a lot of people who would have quite a negative effect with that...i was curious if you were at all opposed to having themes.rockbox.org point to the official section of r-t.org with no links to the unofficial section (which would be redbreva's and we would ahve no access o
22:58:48scorchethemes we would be
22:59:10saratogapreglow: oh so thats doing two shifts at once
22:59:17DoctorPeperI was browsing the Flyspray thingamajig and i found a page on a rockbox startup sound. this sounds like a cool thing to do. what would you need to do to get this working
22:59:18saratogai didn't realize that was possible in arm
22:59:22Bagderscorche: nope, I would be happy do arrange that
22:59:28Bagders/do/to
22:59:38preglowsaratoga: well, it's not, really, there are two instructions doing the shifting, one mov for the first, and an adc for the second
22:59:48gregjDoctorPeper: the worse idea ever, I don't want it to do any sounds on startup..
22:59:50preglowsaratoga: arm supports doing shifts in parallell for a lot of instructions
22:59:50Bagderand that was what I wanted Redbreva to do from the start...
23:00
23:00:00gregjmaybe apart from 'welcome master, awaiting orders'
23:00:05gregj;]
23:00:28scorcheBagder: and have r-t.org split up into an official version and redbreva's personal theme collection (with anything he wants on there) on a different subdomain and not linked on our official section?
23:00:30saratogapreglow: so doing " "M" (16), "M" (16) \" would mean I'm shifting both registers by 16 then?
23:00:38preglowsaratoga: indeed
23:00:50preglowsaratoga: which is what you'd want for your .16 format
23:01:10Bagderscorche: I really don't care what happens to the existing one, as long as we can get an "official" one with fine themes on it
23:01:15scorchealright
23:01:22*amiconn adds a debug readout for 0x600060a0
23:01:23preglowsaratoga: does the code do any multiply-accumulate operations? i'd guess not
23:01:35gregjamiconn: want me to test something mroe ?
23:01:40saratogapreglow: theres more then a few places it could do them
23:01:42DoctorPeperFunny... But in the article. It talks about being able to disable it and to change the sound. I still suport it. Whos with me?!?!?!
23:01:42scorcheBagder: then i will let you know when i need something from you =)
23:01:47saratogawill try that next
23:01:55Bagderscorche: I'll stand by! ;-)
23:02:02preglowsaratoga: cool, since you'd benefit from using another set of macros for that
23:02:07*scorche is set up with an FTP account to copy.rockbox-themes.org and is working on the official version

23:05:06DoctorPeperDoes anyone like the idea of a start-up sound
23:05:31preglowsaratoga: you'll find it all a quick study, i expect, arm asm is pretty straight forward and gcc's syntax is very nice when you get to know it
23:05:47preglowfeel free to ask whenever while i'm still here
23:05:53gregjamiconn: I changed udelay to 255, crash after 2mins
23:05:57amiconnpreglow: Btw, where is this pll denominator value '8' from? ipl? arbitrary?
23:06:03*gregj see the pattern emerging
23:06:06preglowsaratoga: btw, just found out i'll probably have internet access for the next two weeks too, but it'll be more sporadic

23:11:21amiconnThe last one is a post-divider that only seems to work on pp5022 (??)

23:11:53preglowstill good
23:12:07saratogamaybe 400% means it'll work on the PP players?
23:12:09preglowanyway, did you mention what the other fixed point format you use is?
23:12:16saratoga1.31
23:12:19preglowsaratoga: possibly, but we want wider margins than that anyway
23:12:37saratogasorry, 2.30 I guess since its signed
23:12:51saratogano, 1.31
23:13:13saratogaactually, I change the precision all the time as I go, but theres only two types of multiplies

23:18:19saratogamaybe gcc is smart enough to figure that one out
23:18:27preglowperhaps, it depends on the code
23:18:30saratogaor rather 0.31
23:18:49preglowwell, the sign bit does behave as an int bit, so 1.31 is the most descriptive
23:18:55 Quit rhet ("Leaving")
23:19:05saratogaok, wasn't sure what the convention was
23:19:06preglowit's just me being weird and using 's' as a prefix for sign, heh
23:19:15preglowthe convention is Q1.31 or something
23:19:21saratogai tend to think of the whole number as 16 bits anyway since its twos comp
23:19:22preglowbut that still doesn't tell me if there's a sign bit

23:30:30webguest52it shows up in files but not in database
23:31:12linuxstbHave you updated your database?
23:31:27webguest52how? heh
23:31:38linuxstbDunno, but the manual does.
23:32:03bluebrotherenable auto-update of the database or manually update the database from the settings menu.

23:32:41webguest52ah thank you
23:32:49amiconnBut the 32 will cost battery...
23:33:00webguest52should i load to ram?
23:33:36bluebrotherdepends on your usage. If you use it a lot you most likely would want to load it to ram.
23:33:49digin4how do i enable shuffle in nano?
23:33:51preglowamiconn: deed
23:34:10webguest52hmm i turned on auto update for the database but the songs are still in files and not in my database
23:34:32bluebrotherwell, you need to enable dircache and load the database to ram for that to work
23:34:47bluebrotherand of course you need to reboot (as a splash should have told you)
23:34:59bluebrotherbut check the manual, it has all of this information ...
23:35:08webguest52ahyeah i jus told me to reboo
