#rockbox log for 2005-02-17

00:00:41amiconnHCl: I even have one button left on recorder... :)
00:00:49HClnice :x
00:01:23amiconnUp/Don/Left/Right are obvious
00:01:35HClyou'll want a and b next to eachother
00:01:44HClstart somewhere where you can't press it by accident
00:01:54HCland select possibly near a and b as well
00:02:07amiconnI'll assign PAD A = F1, PAD B = F2, START = F3, SELECT = PLAY, QUIT = OFF
00:02:14HCldoes the archos allow multiple keypresses?
00:02:19 Join Digital007 [0] (~acd6899d@labb.contactor.se)
00:02:25Digital007ji
00:02:27Digital007hi
00:02:43amiconnHCl: yes and no.
00:02:57Digital007how is sound for iriverbox coming on?
00:03:15amiconnIt allows multiple keypresses for buttons hooked up on different adc ports, but not within one group
00:03:33HClhm
00:03:43HClwhat about iriver remote/base simultaneous presses?
00:04:17amiconnThis should work (different adc channels) if I read the button driver correctly
00:04:57HCli haven't really looked into how input works in gnuboy, i just made a driver for its interface
00:05:22amiconnOopsss! Binary size == 145 MB (!)
00:05:29HClwoah.
00:05:30HClwhat'd you do
00:05:32amiconnMost likely a section problem
00:06:31amiconnArgh! rockboy needs a .stack section!
00:06:41HClo.o
00:06:54HCldon't all programs.. need a stack...?
00:07:26Bagderthere is a .stack already isn't it?
00:07:29amiconnYes. But the rockbox plugins use the stack of the rockbox main thread...
00:07:36Bagderah right
00:09:11amiconnHCl: May I take a look at your rockboy.map?
00:09:15HClsure
00:09:42*HCl grins. like if he could say no without seeming really, really odd xD
00:12:01amiconnHCl: How many .o files do you have in build-dir/rockboy?
00:12:25HClum.
00:12:28HCllet me check.
00:12:43midkhey, guess what.
00:12:50midki recovered my old breakout code today.
00:13:06HCldoes it work?

00:13:44HClhrm, i think that flac checkin broke my build..
00:14:21linuxstbHCl: I forgot one file and then committed it about 30 minutes after the others. It should be OK now though...
00:14:25HClyea
00:14:32HCli just checked out again and it seems to work now

00:16:18amiconnHCl: Thanks, the same I get
00:16:30amiconnIf I find the cause why I get a bogus stack section and you dont, binary size will be roughly equal to yours (414328 bytes)
00:16:44HClok
00:17:12amiconnThis is still with unmodified lcd driver though
00:17:31amiconnFirst I'd like to get a reasonable compilation result
00:18:49preglowbut yes, now i might actually know how to optimize the codecs
00:19:24HCl :)

00:30:14preglowi take it there's not a gcc hacker present?
00:30:49 Join ashridah [0] (ashridah@220-253-121-235.VIC.netspace.net.au)
00:31:52BagderNix on the mailing list seems like a gcc insider
00:34:00preglowi was going to ask how hard it'd be to add emac support to gcc, but i don't think that's something someone's going to be willing to do for me, heh
00:34:24Bagderprobably not
00:36:30 Quit methangas (" HydraIRC -> http://www.hydrairc.com <- State of the art IRC")
00:36:57amiconnHCl: I have no idea what that stack section comes from. I'll discard it for now. I'll hack a bit on the lcd code, then I'll see how it goes...
00:37:09hubblepreglow: but how would you access the instruction from C?
00:37:34HClamiconn: okilydokiley
00:37:52preglowhubble: very good question
00:37:55hubblepreglow: or do you want an optimization trick that does it automaticly? =)
00:38:02preglownonono
00:38:12preglowi was thinking something along the lines of intrinsics
00:38:48hubblepreglow: aha.. but it is implemented in gas? asm() blocks are nice?
00:38:53preglowgcc does a really good job with 3dnow and sse intrinsics, so i think it'd do good with the emac as well
00:39:01preglowhubble: that's what i'm doing now
00:39:15 Quit Strath ("Client closed")
00:39:24hubblepreglow: ofcourse intrinsics are better
00:39:32preglow#define MACL(x, y, acc) asm volatile ("mac.l %0, %1, %%" #acc : : "ad" ((x)), "ad" ((y)));
00:39:37preglowthere's an example
00:40:26hubblepreglow: ok..
00:40:27 Part hubble
00:40:30preglowbut it's a kludge, gcc doesn't even know the acc registers exist, so it tends to ignore everything i do that clobber sthem
00:40:46preglowunless i make everything volatile, which i've heard doesn't do wonders for code generation
00:48:41ashridahweee, lots of warnings when building the libFLAC code
00:48:49ashridahall the same warning, mind you
00:48:49amiconnHCl: Where is scan. defined/ what is it?
00:49:45preglowashridah: gcc 3.4 problem
00:50:52HClamiconn: structure with scanline info
00:51:35amiconnHmm. I don't seem to understand... where does it come from? How is the row determined?
00:52:29XShocKgrrr.... How do I make sure that interrupt is installed?
00:52:43XShocKi mean i wrote void DMA0(void) __attribute__ ((interrupt_handler));
00:52:49XShocKvoid DMA0(void) {...........}
00:53:06XShocKbut I have a feeling that it is not installed correctly.
00:54:00HClamiconn: lcd_refreshline collects data and builds the scanline into scan.buf
00:54:09HClthe HACKING doc contains some info about the format used
00:54:23Bagdersleep(night);
00:54:25HClpretty much, the lower 2 bits of each byte in buf is the 4 grayscales

01:06:19amiconnHCl: Archos rockboy launches and doesn't crash. It's counting up in the top left corner...
01:06:46HClkay
01:06:49HCltry mario
01:06:55amiconnWhen do I have to expect the first output (with mario)?
01:06:55HClit starts displaying at 14
01:06:58preglowamiconn: counting at what rate?
01:07:26amiconnroughly 4 fps
01:07:40amiconnHowever, I get no display :(
01:07:55HClpaste your vid_update routine?
01:11:36amiconnArgh, found the prob.
01:11:45amiconnI expected it to be called every scanline...
01:11:55HClit gets called every 8 at the moment
01:11:59HClfor the caching stuff.
01:12:33amiconnYes... and the number is always odd... with caused my version to return immediately ... since I want to discard odd lines...

01:13:30HClahh.
01:13:31HClyea
01:13:54HClumm... also look at the scan structure thing, i modified buf and the definition of BUF in order to make caching possible

01:34:20AClets check if libwavpack compiles
01:34:48amiconnHCl: It runs slower (about 2.5 fps) now. Still no output...
01:36:10HClwhat did you modify?
01:37:09amiconnlcd.[ch] and iriver.c
01:37:31amiconnThe buf needs 16 lines (for now), and scanline_index is calculated % 16
01:37:41HCl*nods*
01:37:54HClwouldn't that still only feed you even numbers, and even less?
01:38:25amiconnThe lcd driver the only uses the even lines from scan.buf, and skips every second column (cnt += 2)
01:38:36HCl*nods*
01:38:51HClwell, your routine should be much like mine, really, aside from those changes and the buf / modulo increase
01:39:05HClyou can always uncomment the draw and clearpixel routines
01:39:15HClthey're meant as a legacy/backup thing thats guaranteed to work
01:39:25amiconnYeah. I simply copied your routine and did those changes
01:39:46amiconnI added all changes with #if LCD_HEIGHT == 64 ... #else ... #endif
01:40:31amiconnBtw: I think there is still plenty of room for optimisation in the lcd driver.
01:41:09amiconnThe best thing would be to use asm for the bit shuffle, that would make it fly...
01:41:38HClmaybe, i'm hardly familiar with m68k asm
01:41:52amiconn...this kind of asm routine is rather straightforward... on SH1... I already did similar things in the grayscale lib.
01:42:20HCli suggest using the drawpixel routines while getting it to work though
01:42:30linuxstbAC: Any progress with wavpack?
01:42:30HClfirst get it to work right, slowly, then look at optimizations
01:43:09amiconnm68k shouldn't be hard either... and there are highly optimised routines originally developed for faaast c2p on Amiga, which do pretty much what is needed here as well
01:43:24HClkay
01:44:11preglowgood news
01:44:21amiconnYou Makefile integration is a bit dirty... I always have to remove rockboy.[o|rock] to make it recompile
01:44:26preglowis the lcd blitter a resource hog as it is?
01:44:41midkfo' sho!
01:45:20AClinuxstb: i will use the wavpack decoder desidned for embbled systems
01:45:22amiconnpreglow: The lcd driver, although already optimised, is still a bitshifting mess of hell
01:45:45preglowmidk: it's spelled "fo' shizzle"
01:46:05linuxstbAC: Sounds perfect.

01:52:35amiconnI have some nice bit-"weaving" asm routines that will hopefully speed things up...
01:58:38amiconnYeehah! It works!

01:59:19HClmake pictures
02:00
02:02:14amiconnHmm. I guess it's not really playable. The graphics look rather odd at half the size with no interpolation
02:02:43preglowamiconn: framerate?
02:03:11amiconnAdditionally, there is some graphical garbage at the left & right, because the gameboy screen at 1/2 doesn't cover the whole archos screen width
02:04:15amiconnFramerate varies a bit depending on what happens, but i get ~3.3 fps
02:04:22XShocKaaa... can the interrupt handler function be in plugin?
02:04:23 Quit Digital007 ("CGI:IRC (EOF)")

02:09:17preglowhaha
02:09:18linuxstbAC: You can - it's deifned in firmware/include/
02:09:23preglowso both will fail while taking pictures

02:11:48amiconnpreglow: I tried more than two sets... These NiMH cells tend to be empty when I want to use them... :(
02:12:12preglowamiconn: yes, my camera batteries are always empty if i haven't used it for a while
02:12:39linuxstbAC: No, the Makefile should include -I$(FIRMDIR)/include - look at apps/codecs/libmad/Makefile for an example - you should be able to just copy that (with some minor changes).
02:13:02linuxstbAC: The Makefile reads a text file called SOURCES (in the same directory) listing the .c files that need to be compiled.

02:24:27preglowahhh, finally
02:24:38linuxstbAC: What was the problem?
02:24:42preglowi think i'll go to bed, then
02:25:11AClinuxstb: Makefile problem
02:25:57linuxstbAC: It always is.
02:27:00AClinuxstb: compiles with about 8 warnings :)
02:27:38linuxstbCool. Don't bother to fix those yet - we'll add it to CVS with the warnings (i.e. the original unmodified code), and then fix the warnings afterwards.
02:28:09ACok.. i will write now a wv2wav plugin to test everything
02:28:49linuxstbOK. I've cleaned up my decoders a lot, so it should be easier for you to write one in the same style now.
02:29:25preglowwho'd have thought things would have progressed at this rate
02:29:35amiconnHCl: rockboy never yields, so the hd keeps spinning....
02:30:02amiconnAh, demo mode!
02:31:36linuxstbAC: The current decoding speed record is FLAC at about 8% of real-time on the iRiver. I'm hoping that wavpack will take the record.
02:31:46HClwhat do you mean never yields?
02:32:22preglowcall yield()
02:32:38amiconnRockbox is cooperatively multithreaded... every thread needs to yield() from time to time
02:32:47AClinuxstb: we will see :)
02:33:05linuxstbSo my ???2wav plugins should be doing the same thing?
02:33:21preglowamiconn: does rockbox have a cpu% per thread measurement thing?
02:33:29amiconnnope
02:33:31XShocKhardware guys, help me. :) how should I set up an interrupt?
02:33:38XShocKin iriver
02:34:13HCloh o.o
02:34:14preglowlinuxstb: i guess most things should be doing it from time to time
02:34:32XShocKI have a feeling that void DMA0(void) __attribute__ ((interrupt_handler)); void DMA0(void) {....} does not work well
02:34:47XShocKdo i need to add anything else?
02:34:54linuxstbHow often should it be done? All my plugins have decoding loops which more or less decode one frame of audio on each iteration. Should I put a yield() inside that loop?
02:35:11amiconnXShocK: This cannot work from within a plugin
02:35:34XShocKI already put it into the firmware itself
02:36:01amiconnlinuxstb: There is no general rule for a yield rate, but I'd aim for at least once per tick
02:36:28linuxstbYou mean 200 times per second?
02:36:32amiconnOf course, for your test plugins it isn't really important, but certainly more often than once per second
02:36:44amiconnA tick is 10 ms
02:36:45preglowdoes rockbox always pass control to other threads when you call yield() ?
02:37:25amiconnIirc it's a simple round robin scheduler, so yes, unless some threads are sleeping
02:37:52linuxstbAre there any other threads running on the iRiver at the moment though?
02:38:04amiconnYes of course
02:38:08preglowbacklight, ata, scroll
02:38:14XShocKamiconn: I want to set up a interrupt handler. and I need interrupt vector. i guess the index of the interrupt. How should I do that?
02:38:35linuxstbI assume it's rb->yield() ?
02:39:04XShocKI think I am pretty done with DMA sound, I only cannot catch the interrupt itself.
02:39:09amiconnIf you give your routine the correct name, this should be done automatically. The default handler for interrupts have a weak symbol, so it is replaced by yourt routine
02:39:20amiconnlinuxstb: yes
02:39:33XShocKok. then how do i get the irq vector? :)
02:39:36 Quit Hohoman ("( www.nnscript.de :: NoNameScript 3.81 :: www.XLhost.de )")
02:40:21amiconnXShocK: You don't need to know yourself. Just name your interrupt routine like the vector name.
02:40:42XShocKBut I need the number itself. :)
02:40:48XShocKthe vector
02:41:08amiconnWhy?
02:41:41XShocKi certainly need it... :) because interrupt's vector will be put into DIVR register of the DMA
02:42:08XShocKMaybe I am completely wrong, but I suspect it is right
02:42:46amiconnAh ok. Hmm, then I don't know. Obviously coldfire works a bit different...
02:43:08XShocKmmmm, maybe you can guess? :)
02:43:29XShocKi really don't want to wait one more day, I will go crazy. :)

02:46:04amiconnIn case an archos recorder (v1) owner wants to try rockboy... Get it here: http://arnold-j.bei.t-onlne.de/Rockbox/rockboy-recorder.zip Put rockboy.ajz in the root (or wherever you prefer to keep .ajz's), put rockboy.rock into /.rockbox/viewers and replace your viewers.config with the supplied one. Then put a gameboy rom file somewhere, RoLo romboy.ajz, then "play" the rom file

08:47:21linuxstbHmmm. My H140 is suddenly not booting Rockbox. I've started it, and I just get a completely blank screen. But there is hard disk activity - so I'm hoping it's calculating the fsinfo.
08:47:50linuxstb... Ah, it's now started. So I guess it was calculating fsinfo. Strange.
08:48:07linuxstbBTW, Morning all.
08:48:15Bagdermorning
08:48:50linuxstbIs it possible to display a "calculating fsinfo..." message, or is the LCD not initialised at that point?
08:50:46Bagderis it really rockbox that does that?
08:50:48LinusNit's possible, but only the ata driver knows, and it doesn't have access to the lcd
08:51:04LinusNBagder: yes, it's our ata driver
08:51:14Bagderwhat is it doing more specificly?
08:51:30LinusNit is scanning the FAT, counting the free clusters
08:51:41linuxstbIt's during fat_init() - the symptoms from a user's point of view is a completely blank LCD screen.
08:51:52Bagderdoes it always do that on boot?
08:52:04LinusNno, only if the fsinfo is blank
08:52:09Bagderah
08:52:12Bagderblank
08:52:23LinusNblank, as in uninitialized
08:52:29linuxstbNo, some people had it when first booting after flashing. My H140 never did it, but suddenly wanted to today.
08:53:12LinusNi guess it was invalidated by the fat driver on your pc
08:53:25linuxstbBut maybe it won't be too bad when the CPU is at full speed.
08:53:33LinusNguess not

09:06:33linuxstbMaybe a solution would be to display a message on the LCD before the disk_mount_all() function is called. Just something like "Rockbox initialising, please wait...". Under normal circumstances it would disappear almost instantly, but in case of fsinfo recalc, at least a message wouild be there, and not a blank screen.

09:08:18markungood morning
09:08:49markunTremor now compiles, but I did not make a ogg2wav yet.
09:09:08Bagderlinuxstb: yes, it sounds like a working approach to me
09:09:15Bagdermarkun: nice
09:09:18linuxstbmarkun: Good morning. That's good news. Were there many changes?
09:09:38linuxstbShould it be called vorbis2wav?
09:10:22markunNo, just some small ones. It gives quite some warnings and I didn't get to compile vorbisfile.c (high level api)
09:10:40linuxstbThat's OK, we won't be using vorbisfile.
09:10:57linuxstbI assume it uses stream IO (FILE* etc), which isn't in Rockbox.
09:10:57markunyes, vorbis2wav would be better
09:11:42markunyes, it does
09:11:50linuxstb"AC" is working on wavpack, so we should have 5 codecs soon. More than enough to design a codec API around.
09:12:05Bagderyes
09:12:37BagderI hope to get the SOURCES-sim build up soon too, making it easier to make a sim version that can do this too
09:12:40markunI could fix some of the warnings, but maybe the first commit should have a few alterations as possible?
09:13:10linuxstbBut wavpack is interesting - it has a hybrid mode where the file is compressed losslessly to two files - a normal lossy ".wv" file, plus a ".wvc" correction file. It can either decode the .wv by itself (lossy playback) or use both files to decode losslessly.

09:14:20Bagderthen you have a revision number
09:14:30linuxstbMy approach is to put the unmodified files into CVS first (without linking them into the Rockbox build system), and then make my changes from there. So every change is tracked in CVS.
09:14:46Bagderyes, I guess that is a good way
09:15:09linuxstbOnce it compiles cleanly, then I link it to the build system in CVS.

09:16:39BagderI didn't find your nick in the IrcNicks
09:17:17linuxstbmarkun: As long as you don't commit your modified version of apps/codecs/Makefile, then Tremor won't be built as part of Rockbox. So you can commit in safety.
09:17:28markunI'll put it in IrcNicks then.
09:17:41linuxstbOnce it's compiling cleaning, commit apps.codecs/Makefile.
09:18:00Bagdermarkun: ok, you are in. Just proceed with care and ask if in doubt
09:18:12Lynx_are the codec's speed problems resolved yet? Or does the processor run at full speed?
09:18:15Bagderwelcome aboard
09:18:25markunThanks!
09:18:33linuxstbmarkun: Have you seen the "README.rockbox" files I've put in the other codec directories? We would need something similar for Tremor.
09:18:49markunI'll first do a 'man cvs' first :)
09:18:54linuxstband welcome to the codec club.
09:18:58LinusNLynx_: i am working on the cpu clocking
09:19:08LinusNit isn't trivial
09:19:17linuxstbThe Rockbox website has a useful "brief intro to CVS" page.
09:19:27LinusNlots of datasheet digging to find the timings for the different peripherals
09:19:44Lynx_LinusN: ok :)
09:21:18linuxstbmarkun: One last thing, I've heard that theres a "lowmem" branch of Tremor. Is this the one that you are using? I have no idea if that would be better than the normal Tremor for our purposes.

09:21:56Bagderthe FILES weren't fixed until yday
09:22:08markunNo, I don't think we should use the lowmem brach. It trades in speed for memory.

09:27:38Bagderin case you wanted to know ;-)
09:27:59markunTremor uses alloca in some places, should we change that in malloc + free?
09:28:21 Nick QT_ is now known as QT (as@area51.users.madwifi)
09:29:15linuxstbmarkun: Rockbox doesn't have malloc(). At the moment, I'm using a very simple local malloc() implementation in plugins/lib/xxx2wav.c - there is no free().
09:30:19linuxstbIt's possible that when we implement the real codec system, we would have a proper malloc()/free() implementation using a codec malloc buffer. But ideally we would want to try and avoid that.
09:30:52linuxstbCould you use a static buffer instead?
09:31:58linuxstbIn FLAC, I'm ignoring the VORBIS_COMMENTS block at the moment - I'm thinking that we should write our own parser that can be used by both the FLAC and Vorbis codecs.
09:32:35linuxstbThe FLAC one does lots of inefficient mallocs and frees.
09:33:30markunYes, I think so too. Should we also combine some other code from the all the codecs like the mdct code?
09:34:27LinusNi think we should change the codecs as little as possible
09:35:26markunok
09:35:30linuxstbBut in the long term, a highly optimised "libcodecs" could be useful - with functions such as mdct.
09:36:32LinusNperhaps
09:37:06linuxstbBut I agree 100% that we should leave the codecs as untouched as possible
09:37:11linuxstb.. at the moment.
09:40:19markunIf I use 'cvs add Tremor', will all the files in it also be added to cvs?
09:42:18linuxstbNo, just the directory.
09:43:03markuncvs [add aborted]: there is a version in Tremor already
09:43:04linuxstbThere possibly is a command to do it all at once, but I normally just traverse the directories myself, adding and committing things.
09:43:24linuxstbAh, are there already CVS directories in there from SVN?
09:45:02linuxstbI mean ".svn" directories - maybe they need to be deleted.
09:45:23markunI think the adding worked now. Can I commit the files recursively?
09:46:07linuxstbYou can check the current contents of CVS here: http://www.rockbox.org/viewcvs.cgi/apps/codecs/
09:46:22linuxstbI don't know how to commit recursively - I never do it that way.
09:50:27LinusNyou just "cvs ci" without arguments in the root dir of the dir you want to commit recursively

10:57:50linuxstbI thought that is what happened. Are you saying it doesn't?
10:58:36dwihnoI don't think so
10:58:54dwihnonobody but I would be happier if my guesses are wrong
10:59:05LinusNno you can't
10:59:27LinusNnot on a function level
10:59:47LinusNyou can do it on the object file level, by using a library
11:00
11:00:50dwihno:/
11:01:02dwihnoThat would be pretty swell if the compiler could skip unused stuff
11:04:51linuxstbLinusN: If you create a library, and then statically link against that library, are only the used functions from that library copied into the output file?
11:05:06LinusNyes
11:05:17LinusNlook at the bootloader, for example
11:05:29linuxstbThat's OK then. I was worried I would have to remove unused functions from the codec libraries.
11:05:53LinusNbut remember that if there are several functions in an object file, all of the functions will be included
11:06:05LinusNeven if only one of them is ised
11:06:06LinusNused
11:06:28LinusNnote: a library is a collection of object files, not a collection of functions
11:07:33linuxstbAh, so unused functions in the codecs probably are still being copied? Unless the whole .o file is unused.
11:07:57LinusNexactly
11:08:19LinusNthis is why the plugin grayscale library contains so many .o files
11:08:33linuxstbSo there is no advantage to libraries then (in that respect). I could just link against the individual .o files that I know are needed.

11:25:59LinusNthat's the way the linker does it
11:26:12LinusNno extra flags needed
11:26:19dwihnoaha.
11:26:21dwihnoneato! :)
11:26:28dwihnotoo bad it's only on object level.
11:26:33LinusNprovided that the .o files are in a library
11:26:43dwihnoit would be swell if it would be on a function level
11:26:57LinusNyup
11:26:58dwihnohow do you create a library using gcc? using ar?
11:27:06LinusNyes

12:07:17linuxstbpreglow: Are you talking about my libmad implementation?
12:07:22preglowlinuxstb: yes
12:07:39preglowthat's what i was looking at
12:08:14linuxstbI've taken that code from a program I wrote a couple of years ago. I remember at the time that that dither routine noticably improved the sound quality compared to just truncating the samples to 16-bits.
12:08:21preglowi'll have to do a comparison sometime
12:08:31linuxstbPlease do.
12:08:41preglow'cause i somehow doubt i can hear it
12:08:49preglowmy hearing isn't the best in the world, though
12:09:37linuxstbMy hearing is not the best either when it comes to comparing different versions of the same muisc, but I do remember noticing a big improvement with that dither routine. Buit my memory isn't the best either...
12:09:54preglowhaha
12:09:58preglowi'll check it out sooner or later
12:10:12preglowh1x0 permits higher resolution output than 16, yes?
12:10:17preglowi think someone mentioned 20 bits
12:10:20 Join ripnetuk [0] (~george@82-70-100-230.dsl.in-addr.zen.co.uk)
12:11:10preglowbut yes, i know completely understand all emac dealings
12:11:23linuxstbYes, I think the audio hardware supports 24-bits, but there is another bottleneck (i2s?) that limits it to 20 bits.
12:11:24preglowso look forward to the time i've got time to start optimizing
12:12:00linuxstbBut I'm not sure if the complication of 20-bit samples would be worthwhile. I guess we need listening tests to find out.
12:12:04preglowwhich most certainly won't be for a little while :/
12:12:13preglowwhy is that a complication?
12:13:23linuxstbBecause one sample is then 2.5 bytes. It would also increase the memory usage of the PCM buffer.

12:14:21preglowwell, we really should be flexible with the pcm buffer format anyway, the h1x0 won't be the last player rockbox is ported to
12:14:37preglowand it would have to packed in 3 or preferably 4 bytes, yes
12:15:05preglow4 probably will be faster than 3, the coldfire being a 32 bit processor
12:15:27preglowbut yes, i understand the concern
12:15:31preglowlistening tests will have to be done
12:15:40linuxstbWe need to think about the format the low-level audio driver needs, we don't want to convert between two many different PCM formats.
12:15:48linuxstb^too many
12:16:11preglowpersonally i don't think i stand a chance to hear the difference
12:16:16preglowbut then again, my hearing is a bit damaged
12:16:24linuxstbpardon?
12:16:44preglowhear the difference between 16 and 20 bit
12:17:35linuxstbI would be surprised if I could tell the difference as well. But who knows? Audio is not a science.

17:01:57Quelsarukexited or excited? :D
17:02:06amiconnI hope you mean *excited* ;-)
17:02:58amiconnI have an idea how I can make it run without such a huge plugin ram area (currently the modified version uses 512 KB)
17:03:27[IDC]DragonPIC in the mp3 buffer?
17:03:46amiconnI'll write a small 'loader plugin' which will then load the main binary into the mp3 buffer (towards the end, where the address will be constant)
17:04:07[IDC]Dragonah, no PIC, better
17:04:19amiconnSomething like an overlay in the old days of DOS...
17:04:46[IDC]Dragonthe code (without tables) has no chance for 32 kB?
17:05:27amiconnYes, it will be linked to a fixed address. I'll use ram_end - 512 KB, this leaves 480 KB (without the original plugin ram)
17:05:42*[IDC]Dragon has 8 MB
17:06:08amiconnThen you'll need to compile yourself. This should enable loading of all gb roms.
17:06:24amiconn2 MB boxes cannot load all roms.
17:06:27[IDC]Dragonmario is only 64 KB?
17:06:31amiconnyup
17:06:39amiconnPokemon yellow is 1 MB
17:06:47[IDC]Dragonquite a range
17:06:52amiconnThe maximum is 4 MB iirc
17:07:24amiconnThe CPU is a Z80 lookalike. I wonder how the >64 KB roms are addressed
17:07:44[IDC]Dragonmust be bankswitched or so
17:07:58amiconnMany banks there are...
17:09:02[IDC]Dragondid you look at the CPU interpreter, about how muck "potential improvement" there is?
17:09:18amiconnNot at all yet.
17:09:59[IDC]Dragononce there's been a famous console emulator, I forgot for which
17:10:11amiconnI only looked at the lcd driver, and there was indeed some potential. The C version (without proper scaling 160->112 but only halving to 80) did ~3.3 fps.
17:10:11[IDC]Dragonbut Zelda was the killer app
17:10:21amiconnThe asm version with scaling does 6 fps..
17:10:35[IDC]Dragonyes, saw that, nice
17:11:08[IDC]Dragonthe above re-used code which was already interpreted, iirc
17:11:09amiconnI hope to speed it up further by skipping the calculation of the dropped scanlines completely
17:11:58amiconnNo, but the C version uses individual bit shifts by 1..7, then ORs together
17:12:53amiconnThe asm version tests the source bits, the assembles the output byte by rotating in the carry bit
17:14:00 Join Stryke` [0] (~Chairman8@resnet-241-86.resnet.umbc.edu)
17:14:02amiconnI hope to get this to work as well for 68K, because it allows to drop another loop across the scanline. (That's part of the fps gain with asm)
17:14:16amiconnThe asm is only the core loop, 10 insns on SH1
17:16:50amiconnOf course I have to keep a (changed) C version to make it work on the sim (or use x86 asm - urgs!)

18:58:32CoCoLUSso porting standard c++ apps to m68k/rockbox is fairly "easy" ?
18:58:32preglowindeed
18:58:35preglowc
18:58:37preglownot c++
18:58:45CoCoLUSc only? :)
18:58:55preglowof course not, but gnuboy is c
18:59:04preglowand we'll try to stick with c
18:59:12CoCoLUSok
18:59:13HClit completely depends on the application
18:59:15CoCoLUSc# would be nice :P
18:59:17HClgnuboy was written for portability
18:59:20preglowbut yes, the difficulty varies
18:59:26preglowCoCoLUS: haha, forget it
18:59:30HClew.
18:59:32HClc#
18:59:39preglowc# is rather nice
19:00
19:00:05preglowbut i mostly use c++ these days
19:00:09preglowi don't like it very much, though
19:00:15CoCoLUSwell bringing the whole .net fx to the iriver would be quite impossible, i think
19:00:31preglownah, not impossible
19:00:34preglowbut very impractical
19:00:40CoCoLUSnothings impossible :)
19:00:41HClthere isn't a c# for linux, is there?
19:00:42preglowand it would perform badly
19:00:46preglowHCl: there is
19:00:47CoCoLUShci, there is
19:00:47preglowHCl: mono
19:00:48CoCoLUS:)
19:00:52HClhrm.
19:00:54HClwell.
19:00:56CoCoLUSwww.go-mono.com
19:00:59HCli'll still stick with java / c / c++
19:01:07preglowand i'll stick with c/c++/perl
19:01:08CoCoLUSc# == java :)
19:01:13HCleh.
19:01:18HClc# was made by microsoft.
19:01:22preglowyes
19:01:22HCli trust sun more than microsoft.
19:01:25rasherthey're very alike
19:01:28rasherhrm
19:01:32CoCoLUSi trust neither
19:01:40rasherI don't put Sun much higher than MS
19:01:50preglowbut yes, c# is an ok language, beats c++ by far
19:02:00preglowand once the mono guys are done, you're not dependent on microsoft tools
19:02:11CoCoLUSif they're ever done...
19:02:17preglowthey've gotten pretty far
19:02:19preglowand it's a huge job
19:02:23CoCoLUSi know
19:02:35CoCoLUSbut the whole windows forms implementation...
19:03:06CoCoLUSi think they will never get it so far so you could take just any windows application written in c# and run it unter mono
19:03:12preglowahhh, that might be so
19:03:14CoCoLUSif it has any kind of graphical output :)
19:03:34preglowbut windows forms stuff is very tied to the windows api, so small wonde¨r
19:03:39CoCoLUSyeah

19:35:44Quelsaruknow i get a splash message when i boot rockbox
19:36:01Quelsaruksomethhing like playlist buffer empty or something like that
19:36:06amiconnI know, have to investigate that
19:36:13Quelsarukoh
19:36:13Quelsaruk:)
19:36:26Quelsarukso i don't need a goat to clean that
19:36:28Quelsaruk:)
19:36:29Quelsarukok
19:36:32amiconnIt is caused by the modified viewers.config, but doesn't seem to hurt
19:36:44Quelsaruk:)
19:44:42Quelsarukbtw
19:44:59Quelsarukrockboy is only black and white
19:45:02Quelsarukisn't it?
19:45:11amiconnyup
19:45:32CoCoLUSbecause of the iriver display i assume
19:46:05Quelsarukand i suppose that it's hard to make it somehow greyscale...
19:46:22CoCoLUShm
19:46:52CoCoLUSi own that damn player a year and can't tell without looking at it if it's grayscale or monochrome...
19:46:53amiconnThe iriver display is able to do 2 bit greyscale - an exact match for the gameboy display.
19:47:21Quelsarukamiconn: but archos one?
19:47:25amiconnHowever, this mode is not yet used in rockbox, and I guess it's not high priority to add this
19:47:40amiconnArchos does only b&w natively
19:47:43Quelsaruki think they want music before greyscale
19:47:43Quelsaruk:D
19:47:52CoCoLUSyeah
19:48:04CoCoLUShowever, using the full capabilities of the display is quite important imho
19:48:06amiconnThere is my grayscale lib, but this would eat too much performance to also handle the gameboy emu
19:48:19Quelsarukyeah amiconn, but if you were able to "play" snow and cube in archos player...
19:48:20Quelsaruk:D
19:48:33rasherYou are.
19:48:40CoCoLUSmonochrome.
19:48:41rasheroh
19:48:45rashernevermind.
19:48:52rasherI read that wrong.
19:48:59Quelsarukrasher: :D
19:49:06rasherIGNORE ME
19:49:08rasherI AM NOT WELL
19:49:12Quelsaruk:P
19:54:31amiconnHCl: r u there?
19:55:35Quelsarukamiconn: but your greyscale uses more than just 2 bit greyscale, isn't it?
19:55:36Quelsaruk:D
19:55:44amiconnyup.
19:55:56Quelsarukso maybe.. if it's only 2 bit greyscale?
19:56:01Quelsaruk;)
19:56:23amiconnHowever, the amount of cpu power taken by the refresh does not depend on the number of greyscales.
19:56:38amiconnIt only depends on the size of the greyscale overlay.
19:57:10amiconnFullscreen greyscale takes about 50% cpu power for the refresh alone.

21:29:56amiconnHCl: What is rom.gb on your ftp?
21:30:00HClum.
21:30:09HClthat was my first testcase
21:30:16HClhomebrew demo rom
21:30:23amiconnAh.
21:30:29HClneeded something really basic to test rockboy in its early stages
21:31:04TangSo the CPU always run at 11MHz?
21:31:30HClat the moment, yes.
21:31:37HCllinus is working on it.
21:32:01CoCoLUSihp-overclocking, sounds nice
21:32:12amiconnNo overclocking.
21:32:23HClno overclocking planned
21:32:30HClbut its possible for people who are dumb.
21:32:35HCland seriously want to try it
21:33:20TangThanks HCl
21:33:26Tangi see
21:33:54Tangwas just wondering as sometimes some progress weren't in the Wiki
21:33:59CoCoLUSif the gameboy emu gets fast enough, we won't need overclocking ;)
21:34:08Tangand i've not access to IRC often
21:34:10Tang;)
21:34:16HClgameboy dynarec should provide more than enough speed.
21:34:50Suckadouble speed mario!
21:34:51Sucka;D
21:35:04CoCoLUSone magic mushroom too much :)
21:35:35preglowTang: clocking the cpu correctly takes alot of time, i'm pretty certain the wiki will be updated once it's done
21:35:44preglowhaha, i'd hardly call fly agarics "magic"
21:35:51preglowdangerous, perhaps
21:36:10preglowit's a wonder mario's not foaming at the mouth and raging around like a mad man
21:36:15preglowhe must have built up a tolerance
21:36:22TangAh okay thanks Preglow
21:36:31Tangno misunderstanding
21:36:38Tangi'm not making pression
21:37:05CoCoLUSbest thing would be playing mario while listening to some songs, gapless, ogg
21:37:13Suckamario has moved onto ketamines ;)
21:37:20Tangi do know an open source project is based on vonlunteerness and free hours
21:37:23Tang:)
21:39:36preglowSucka: he'll be doing smack before long
21:39:49preglowit's a wonder he still lives to feature in gamecube games
21:39:50Suckamario mario mario....what happened
21:40:33Suckayou know its all going pearshaped when you start hallucinating giant eggs with green spots
21:42:29bg_hehe... it would be funny if someone photoshopped up an enquirer-esque picture of mario looking tired and confused from drug use
21:42:35preglowhahah
21:42:53preglowagainst a psychedelic background
21:42:57preglowshrooms coming out of his pockets

22:50:44FlexHi had a JB recorder, now i have an iriver H320 :)
22:51:14FlexHi'd like to help rockbox team but i don't kwow how
22:54:06Bagderamiconn: anything I can do to help?
22:56:50***Saving seen data "./dancer.seen"
22:56:52amiconnI don't get what this depfile thing means, and how it is supposed to work
22:57:11amiconnI'm trying to get the rockboy Makefile sorted.
22:57:28amiconnI need a flexible method.
22:58:13amiconnFor iriver, rockboy.rock should be the plugin itself
22:58:20Bagderthe depfile stuff is the make.inc's method of generating a file with dependencies
22:59:57amiconnI thought that it contains dependencies, but how are the dependencies defined, and what are they used for? It seems some Makefiles work without a depfile
23:00
23:00:34Bagderthe dependencies are used so that when you change a header file, all C files that use that header get recompiled
23:00:58preglowa very good arrangement to have, god knows how many times i've had bugs turn up over that
23:01:21amiconnFor archos, rockboy.rock should be a little loader plugin that loads the main rockboy code blob at a fixed address into the mp3 buffer after grabbbing it.
23:02:27Bagder.rock files use (and depends on) includes too
23:03:26amiconnHow could I define conditional rules, i.e. rules valid for one target, but not for another?
23:04:13Bagderit only makes deps for files in SOURCES that survived a preprocess
23:04:53amiconnHmm. How could I explain...
23:05:20amiconnI need a separate liinkfile for rockboy, which will reside in apps/plugins/rockboy
23:05:50 Join coob [0] (pen0r@host-84-9-63-253.bulldogdsl.com)
23:05:51Bagderaha
23:05:51amiconnThis links rockboy_main to the plugin start address for iriver, and to the special fixed address for archos
23:06:06Bagderyou mean the plain .rock build rule is not good enough for it?
23:06:27amiconnNo, since rockboy is more than one source file
23:06:54coobto anyone working on the libflac stuff: someone working on ipod linux has optimised mpd's flac stuff quite a bit, so http://ipodlinux.org/MPD might be worth checking to save yerselves some time...
23:06:54amiconnplus I need to create rockboy.rock differently depending on target
23:07:04Bagderright, the build stuff for plugins assume a single file...
23:07:20Bagderamiconn: then you add a separate $(OBJDIR)/rockboy.rock rule
23:07:28amiconnFor iriver, rockboy.rock would be a simple copy of the linked & stripped rockboy_main.bin
23:08:03Bagdercoob: interesting
23:08:10amiconnFor archos, rockboy.rock would be the usual plugin creation path, and I would have to create an additional file
23:08:49amiconnIm not 100% decided about the name, rockboy.ovl or something like that
23:09:08coobheh is rockboy in cvs yet? we need to pilfer that
23:09:26coobbe a bit shitty to control on an ipod tho
23:09:31amiconncoob: Guess why I'm fiddling with that make stuff? :)
23:09:39coobah :)
23:10:07coobi take it most of the modifications were libc stuff and the sys/iriver thing?
23:10:15Bagderthose ipodlinux guys should go Rockbox
23:10:17Bagderseriously
23:10:20amiconnBagder: Is it possible to use some if...else... construct for defining the rules?
23:10:28Bagderamiconn: yes it is

23:11:25HCljust curious.

23:13:18HClsortof.
23:13:33HCli'm not much of a hardware person
23:13:38Bagdercoob: that would be another benefit of going Rockbox ;-)
23:14:12Bagderamiconn: it always runs make in that dir to check
23:14:20coobwell now you're porting to iriver i guess a lot more code can be shared, especially on the codec side of things
23:14:20Diwayhum, how do I get the 'codecs' dir with cvs ? I can't compile rockbox without it :/
23:14:42amiconnBagder: How?
23:14:44Bagdercoob: yes. we're porting to the Gmini as well
23:14:53muesli-g'mornin
23:15:20Bagderamiconn: the "all:" line says it depends on the libplugin, and then on the libplugin rule it runs 'make -C lib'
23:15:39coobhow's ram latency with the iriver? tremor runs like shit cos the ipod's only fast ram is the 96k of iram..
23:15:41amiconnAh cool, was just about to ask that :)
23:16:13Bagderram latency?
23:16:34rasherwouldn't the lowmem tremor fit in that?

23:32:04amiconnBagder: Where do all those tool definitions for the Makefile (CC, OBJCOPY etc.) come from?
23:32:29Bagderamiconn: the root Makefile, in the build dir. it 'exports' them so they are globally accessible
23:32:38amiconnAh.
23:32:51Bagderamiconn: that's a GNU make feature not globally available
23:33:27amiconnI need 'cp'
23:33:51Bagderwell, cp is gonna be cp on all builds

23:35:34Bagderand my upcoming "unification" will be very hard to adapt to msvc
23:36:04amiconnYes, most probably.
23:36:28Bagderif msvc should be used again, we should still use the regular makefiles and just setup the proper CC and flags etc
23:37:44amiconnI don't know how msvc handles the build process at all. I never used it.
