| 00:00:00 | HCl | they hide its uglyness with defines |
| 00:00:10 | HCl | well, once the basic idea its there its fairly simple |
| 00:00:14 | amiconn | The cpu emu as-is is really slow. |
| 00:00:16 | HCl | hold on, let me cough you up a tarball |
| 00:00:20 | Patr3ck | No one else got the floating point exception error for x11 iriver sim? |

| 00:00:46 | rasher | Not that that's any help |
| 00:00:54 | rasher | But at least it isn't *totally* broken |
| 00:01:07 | pillo | preglow: I thought that too... that's why I'm here :) |
| 00:01:20 | HCl | its not finished |
| 00:01:26 | rasher | Patr3ck: did you update from cvs recently? |
| 00:01:32 | Patr3ck | Yes |
| 00:01:38 | HCl | and it'll scream "ah! unimplemented opcode!" if you try to run it, or at least, it should. |
| 00:01:38 | Patr3ck | Two minutes ago |
| 00:01:40 | rasher | heh |
| 00:01:46 | amiconn | HCl: When there is no graphical output, the cpu core does ~32000 z80 insns per 'frame'. From the framerate I get on archos, I calculated the average host cpu clocks per emulated cpu clock |
| 00:02:02 | HCl | amiconn: i think dynarec will make a massive speed improvement |
| 00:02:09 | amiconn | Guess what: 100 (!) clocks! |
| 00:02:18 | HCl | hehe. |
| 00:02:25 | rasher | That's a whole bunch of clocks. |
| 00:02:31 | HCl | for at least all the loading instructions, 1 z80 instruction -> 1 m68k instruction |
| 00:02:51 | HCl | that is, if it'll work. |
| 00:02:53 | amiconn | Do you hold all z80 registers in m68k registers? |

| 00:02:59 | HCl | i'm having debug nightmares over this already. |
| 00:03:03 | HCl | yea. |
| 00:03:06 | HCl | well, most. |
| 00:03:13 | HCl | i don't have the flags |
| 00:03:17 | amiconn | Then this should be possible on sh1 as well |
| 00:03:25 | HCl | i have 1 8bit reg in each 32bit reg |
| 00:03:30 | HCl | its inefficient, but its faster. |
| 00:03:46 | HCl | inefficient spacewise anyways |
| 00:04:02 | amiconn | I thought about making a highly optoimised interpretive core, and my first thought was to only hold certain registers in host registers |
| 00:04:07 | HCl | take a look at it... |
| 00:04:18 | * | HCl scratches his head and hmz. |
| 00:04:31 | HCl | oh, delete cpudyna.c |
| 00:04:39 | HCl | i split that into cpu.c and dynarec.c |
| 00:04:47 | amiconn | I could always move more z80 regs to host regs later |
| 00:04:50 | HCl | coding dynarec = fun |
| 00:05:09 | HCl | take a look at dynarec.c.. |
| 00:05:24 | preglow | amiconn: how many players are with character cell lcd displays? just the archos player? |
| 00:05:26 | amiconn | Btw, number of m68k regs ~ number of sh1 regs, so porting shouldn't be that hard |
| 00:05:43 | amiconn | preglow: As of now supported, yes. |
| 00:05:56 | preglow | pillo: i really think it'd be worth it, yes :) |
| 00:06:20 | HCl | the getupper/putupper is legacy from my old 2-gameboy-regs-in-one-m68k-reg implementation |
| 00:06:26 | amiconn | There once was neo support in rockbox, but it was dropped. It never really worked, and the neo guys forked some time ago |
| 00:06:37 | amiconn | The neo also had a charcell display |
| 00:07:17 | amiconn | I'd vote for having one single viewer plugin for both display types |
| 00:08:47 | Patr3ck | I just tried again from scratch, same error, strange |
| 00:08:48 | pillo | aha ok |
| 00:08:58 | pillo | but that's going to be a bit cumbersome... i'll try |
| 00:09:08 | preglow | amiconn: even thought the two wouldn't really share much code? |
| 00:09:30 | amiconn | If done properly, they should |
| 00:09:46 | Patr3ck | What exception, I thought rockbox is pure c code |
| 00:10:30 | pillo | amiconn: i'll think about it a bit more then |
| 00:10:57 | pillo | thanks, and keep up the good work! |
| 00:10:58 | amiconn | Simply assume width=1 for all glyphs on a charcell display, drop the calls to functions which calculate the glyph widths, and you're done |
| 00:11:06 | rasher | My understanding is that the policy is to keep it C unless the benifits from using host-specific asm outweigh the disadvantages |
| 00:11:43 | amiconn | pillo: I planned to look into the viewer myself, but did not yet find the time to do it. |
| 00:11:46 | preglow | rasher: that should be common sense as well as policy ;) |
| 00:12:11 | rasher | True. |
| 00:12:20 | Patr3ck | rasher: The error looks like a c++ exception ?!? |
| 00:12:20 | pillo | amiconn: good, i'll see what I can do! |
| 00:12:45 | pillo | HCl: can't wait for the rockboy to rock ;) |
| 00:12:57 | pillo | night all |
| 00:12:59 | rasher | Patr3ck: oh my.. sounds ... interesting.. maybe it's not even rockboxui exploding? |
| 00:13:29 | amiconn | pillo: I used to have a list of issues I wanted to fix, but can't find it atm |
| 00:14:00 | Patr3ck | rasher: maybe the codecs that were added, it stopped working for me at that time I think... |
| 00:14:26 | rasher | hrm.. maybe try doing a checkout before the codecs were added? |
| 00:14:45 | Patr3ck | I know I should start gdb now and take a real look where this exception comes from... |
| 00:14:56 | preglow | Patr3ck: codecs _shouldn't_ use floating point, at least |
| 00:15:15 | preglow | but then again, no parts of rockbox should, heh |
| 00:15:15 | HCl | heh |
| 00:15:18 | Patr3ck | Right, integer arithmetric and stuff... |
| 00:15:25 | preglow | but yes, gdb |
| 00:16:12 | Patr3ck | OK, it will be my first time... always worked with vc++ until I met rockbox |
| 00:16:36 | amiconn | HCl: My thoughts of which registers should always be in host registers during emu: PC, A, and flags |
| 00:16:51 | amiconn | The correct flag emulation is rather important for z80 |

| 00:22:46 | preglow | bobx2001: so we see |
| 00:22:51 | amiconn | HCl: I have an asm-optimised implementation of updatepatpix() now. Doesn't push the frame rate significantly... at least not with the 2 roms I tried |
| 00:23:18 | bobx2001 | what applications are you guys making? |
| 00:23:20 | HCl | okay |
| 00:23:25 | bobx2001 | i know your making rockbo |

| 00:23:41 | preglow | bobx2001: everyone's working on different things |
| 00:23:55 | bobx2001 | ok |
| 00:24:16 | amiconn | HCl: However, I did a slight alteration that pushes the framerate by >5 %. And I made rockboy play more fair in the multithreaded rockbox.... |
| 00:25:31 | HCl | nice. |
| 00:25:38 | HCl | yea, it doesn't do threading yet |
| 00:25:53 | HCl | i'm kind of wanting it in cvs so we can easily merge changes.. |
| 00:26:03 | amiconn | Yea. |
| 00:26:46 | HCl | oi. |
| 00:26:48 | amiconn | Unfortunately the simulator builds on cygwin are totally broken with the new build system, so I cannot test anything simulator-related until it is fixed |
| 00:26:49 | HCl | i'm lucky. |
| 00:26:59 | HCl | i just did an rm * in my plugins dir by accident. |
| 00:27:12 | HCl | because it wasnt -r, it didn't delete my rockboy sources |
| 00:27:17 | HCl | *checks out again* |
| 00:27:21 | rasher | Careful tiger :) |
| 00:27:29 | HCl | mhm. |
| 00:27:34 | thegeek | hehe |
| 00:27:46 | amiconn | ...and without being able to test, I do not want to mess up cvs... |
| 00:28:20 | amiconn | I tried fixing that together with Bagder yesterday, but we didn't find a solution yet :( |
| 00:28:27 | HCl | yea. |
| 00:28:38 | preglow | the clashing headers issue? |
| 00:28:42 | amiconn | yup |
| 00:28:55 | preglow | wouldn't the only real solution to that be renaming the rockbox ones? |
| 00:29:28 | HCl | i pretty much agree. |
| 00:29:35 | HCl | having rockbox_stdio.h |
| 00:29:36 | amiconn | I think that should fix the problems once and for all. However, I don't know whether this is desired |
| 00:29:39 | HCl | is much clearer anyways |
| 00:30:04 | HCl | problem is with porting you'd have to adjust everything |
| 00:30:10 | amiconn | I just had another idea, please correct me if I'm wrong: |
| 00:30:14 | preglow | amiconn: i can't see how anyone can not desire it, it is cleaner both semantically and practically, but yes, lots of work |
| 00:30:51 | amiconn | - The header files are already grouped by function. |
| 00:31:43 | amiconn | - I suggest splitting that a bit more, into those that contain rockbox specifics and those that define posix functions |
| 00:32:02 | preglow | the posix ones could do a ifdef check |
| 00:32:22 | amiconn | preglow: Unfortunately not. |
| 00:32:28 | preglow | why not? |
| 00:33:03 | amiconn | Because some typedefs in the system includes do not provide magic defines to protect from redefinition |
| 00:34:24 | amiconn | By having the posix includes in separate dir(s), we could easily select between rockbox posix and system defines by adding/not adding the rockbox posix defines to the include path |
| 00:36:29 | preglow | yup |
| 00:36:31 | preglow | sounds pretty good |
| 00:36:37 | preglow | and clean |
| 00:37:10 | amiconn | One problem remains - functions that have the same name, but different syntax/usage. |
| 00:37:35 | preglow | rename them :p that should be avoided anyway, heh |
| 00:37:51 | amiconn | The only function that i remember causing this is sleep() |
| 00:38:37 | | Quit quelsaruk ("KVIrc 3.0.1.99 'Realia'") |
| 00:38:56 | amiconn | Posix sleep(n) is sleep n seconds (and wake up by an event). Rockbox sleep(n) is sleep n*10 ms |
| 00:40:22 | preglow | yes, that's not good |
| 00:40:23 | rasher | oh my |
| 00:40:31 | preglow | it should not have been called that |
| 00:40:38 | rasher | that's an odd definition of rockbox sleep(n) |
| 00:41:17 | amiconn | preglow: I agree. Will discuss that with Bagder asap. |
| 00:41:45 | amiconn | Then I face the tedious task to walk through all rockbox headers and separate them... |
| 00:41:52 | preglow | heh |
| 00:41:58 | preglow | it very probably has to be done |
| 00:42:29 | amiconn | Hmm. I'd need a build envy on Linux, or someone who has one to test my changes.... |
| 00:42:51 | amiconn | cygwin is obviously not very posix compliant.... |
| 00:42:59 | rasher | amiconn: I do |
| 00:43:02 | rasher | and I could |
| 00:43:45 | amiconn | Okay. I'll talk to Bagder when he's around. |
| 00:44:09 | amiconn | HCl: I'll work on the archos overlay loader in the meantime. That shouldn't be hard |

| 00:45:40 | amiconn | I simply need to define a little header format, that includes a magic, the load address, the length, and the plugin api version it is compiled for |
| 00:46:18 | HCl | *nods* |
| 00:46:26 | amiconn | My loader plugin would then load the header, claim the mp3 buffer, check whether the overlay fits, then load it and run it. |
| 00:46:49 | HCl | ohyea.. hm. |
| 00:46:54 | HCl | dynarec needs a fair amount of memory |
| 00:46:56 | thegeek | hmm, would it be a big job to migrate away from using the mp3buffer later on? |
| 00:47:03 | HCl | dunno how well the archos will do on that aspect |
| 00:47:09 | Patr3ck | gdb stops with Program received signal SIGFPE, Arithmetic exception. |
| 00:47:18 | thegeek | would be a shame not beeing able to listen to mp3's at the same time as playing gb(if the dynarec works as well as it should;) |

| 00:48:49 | amiconn | thegeek: I will certainly be impossible on the archos, and imho not feasible on iriver as well |

| 00:50:02 | preglow | well |
| 00:50:02 | Patr3ck | I thought I spotted an option check for that in the configure script |
| 00:50:05 | preglow | it's 68k asm :P |
| 00:50:05 | thegeek | if it produces fair quality, it could be usefull sometimes |

| 10:41:31 | XShocK | hmmm... rockbox does not boot. |
| 10:41:50 | XShocK | when reset, cookie works and boot the original. |
| 10:42:11 | XShocK | when trying to boot rockbox i just hangs with red led on. |

| 10:42:27 | markun | linuxstb: I use FreeBSD so I changed a few things to get it to compile, but it used to work so I don't know what I did wrong. Will look at cvs diff. |
| 10:43:11 | amiconn | markun: Currently, all simulator builds are not working *on cygwin*. However, these builds fail much earlier due to conflicting/ missing prototypes |
| 10:45:05 | XShocK | amiconn: what do you mean by "all simulator builds are not working *on cygwin*" ? it does not work not or never worked, because i had no problems running simulator, didn't test new stuff with audio codecs yet though.. |
| 10:45:24 | XShocK | *it does not work NOW or... |
| 10:46:25 | amiconn | markun: "Currently,...", that means since Bagder introduced the new build system (on friday) |
| 10:46:52 | XShocK | ok |
| 10:48:08 | XShocK | so, does anybody had that problem with booting rockbox? |
| 10:48:50 | markun | XShocK: I have no problems. Did an cvs update this morning and rebuild the firmware. |
| 10:49:09 | Patr3ck | linuxstb: mine abort with floating point exception when started :-( |
| 10:49:27 | amiconn | HCl: My overlay loader for rockboy on archos is working :) |
| 10:50:32 | amiconn | markun: ??? |
| 10:50:40 | XShocK | I actually have this problem with an old not up-to-date version of rockbox. |
| 10:50:48 | markun | amiconn: this is what I changed to get it to compile on freebsd so far, can you see if I made any studpid mistakes? |
| 10:50:49 | linuxstb | markun: on cygwin, I think the problem is conflicts between the system includes and the rockbox firmware includes (those in firmware/include). It's very likely to be a similar problem with FreeBSD. |
| 10:50:56 | XShocK | and i really did not update anything from cvs |
| 10:52:19 | linuxstb | XShock: could it be that Rockbox is recalculating the fsinfo? That happened to me the other day - you just need to wait a few minutes, and it will then start. |
| 10:53:38 | XShocK | aah, maybe. I just do not understand why would it do that since the only thing that i did yesterday was listening to a couple of songs. |
| 10:54:25 | linuxstb | I had the same problem, it worked fine since I flashed, and then suddenly one day last week, it decided it needed to calculate the fsinfo.. |
| 10:54:45 | amiconn | markun: I don't spot any obvious mistakes. I only wonder about the extra x11 include... |
| 10:54:48 | XShocK | scandisk did the job, didn't need to recalculate. :) |
| 10:55:22 | linuxstb | I spoke to Linus and Bagder about it on IRC, and they decided my O/S (Linux) must have invalidated the fsinfo during the previous time I used it. |
| 10:55:24 | XShocK | that actually is more confusing why did it happen |
| 10:55:43 | amiconn | markun: Btw, the ssize_t declaration is also a problem on cygwin, but there are more and different ones |
| 10:55:44 | markun | amiconn: it could not find the header files so I added it there. It works for you without it? |
| 10:55:46 | linuxstb | But they didn't know why that would happen. |
| 10:56:23 | amiconn | markun: It used to work. Currently, I can't compile any simulator. |

| 13:50:57 | ashridah | preglow: there's plenty of m68k simulators, the problem will be finding one that supports the emac |
| 13:51:29 | ashridah | and other coldfire features |
| 13:58:24 | preglow | ashridah: not really essential for profiling, we really want to find how things perform without emac right nowe |

| 14:00:41 | amiconn | yup |
| 14:00:46 | [IDC]Dragon | :-) |
| 14:00:59 | amiconn | I've tried your activity icon, works nicely |
| 14:01:15 | [IDC]Dragon | I was also wondering if the activity is inverted for the old bridge |
| 14:01:15 | amiconn | However, I ask myself what the icon should resemble? |
| 14:01:30 | [IDC]Dragon | how do you know, and the level? |
| 14:01:39 | [IDC]Dragon | the icon is a disk |
| 14:01:39 | amiconn | [IDC]Dragon: It is, I've documented it in the wiki. If you would have checked... |
| 14:01:48 | [IDC]Dragon | but I don't like it neither |
| 14:01:55 | preglow | ahh |
| 14:01:57 | preglow | so that's what that is |

| 14:04:11 | CoCoLUS | whats the dynarec status? :) |

| 14:07:33 | [IDC]Dragon | to the users, internal is no mmc |
| 14:08:07 | amiconn | HCl: The loader actually "wastes" some ram. Plugin ram area is 32KB on archos, of which the loader only takes ~600 bytes |
| 14:08:15 | [IDC]Dragon | the icon can be as wide as the clock was |

| 14:48:47 | DMJC | wtf? |
| 14:48:57 | DeadMan | or is it just showing the tag and not outputting? |

| 14:49:21 | DMJC | yeah, how is sound coming? |
| 14:49:30 | DeadMan | probably just a font test |
| 14:49:35 | DeadMan | I dunno |

| 15:30:41 | linuxstb | Looking at synth.c - if FPM_DEFAULT is defined (which it is - see the Makefile), then OPT_SSO is enabled anyway. So I think the current speed is already with OPT_SSO enabled :-( |
| 15:31:13 | preglow | how do i use the mad decoder viewer? |
| 15:31:20 | preglow | looks like rockbox hooks the mp3 first |
| 15:31:59 | linuxstb | You need to hold down the joystick, and then use "open with". Or you may want to rename your MP3 files to .mp3.mad, and then modify viewers.config |
| 15:32:13 | preglow | ok |
| 15:32:15 | linuxstb | ^hold down the joystick button |
| 15:32:29 | preglow | yeah, figured as much |
| 15:32:57 | preglow | you don't count disk acitivity in the timing? |
| 15:34:01 | linuxstb | Yes - the "speed" just uses the number of ticks (100 ticks=1 second) since decoding started. You could disable the disk write if you wanted. |

| 15:47:10 | markun | Don't know if I will be capable of doing this, maybe. |

| 19:15:26 | FiZZ | hehe well im curious about the H1x BDM interface |
| 19:16:38 | preglow | don't know much about it, but some |
| 19:17:16 | FiZZ | well have there been any attempts about a H3xx ? |
| 19:17:41 | preglow | no, too much to be done on the h1x0 yet |
| 19:17:51 | preglow | but the bdm interface should fit like a glove in the h2x0 |
| 19:17:54 | preglow | h3x0, yes |
| 19:18:23 | FiZZ | yeah I would assume that too |
| 19:18:41 | FiZZ | well i have access to some BDIs |
| 19:18:56 | FiZZ | thet bdm they "built" on the site seems very very geekish lol |
| 19:19:10 | FiZZ | i guess a bdi2000 or 4000 would work like a dream though |
| 19:19:59 | preglow | i don't know, but there's not much we _need_ a bdm for now anyway |
| 19:20:15 | FiZZ | yeah |
| 19:20:20 | preglow | primary work on h3x0 should be to first map out the differences in the hardware |
| 19:20:27 | FiZZ | im guessing the hardware difference in a h1xx and h3xx isnt really big |
| 19:20:35 | preglow | that would be my guess as well |
| 19:20:40 | preglow | the obvious difference would be the lcd |
| 19:20:49 | FiZZ | yeah, lcd controller is different ;) |
| 19:20:57 | FiZZ | but i guess the uP is different too |
| 19:21:04 | preglow | nope |
| 19:21:06 | FiZZ | might most likely have other units |
| 19:21:09 | FiZZ | exact same one ? |
| 19:21:16 | preglow | think both are 140mhz 5249 coldfires |
| 19:21:17 | preglow | afaik, yes |
| 19:21:19 | FiZZ | well |
| 19:21:21 | FiZZ | sure |
| 19:21:42 | preglow | both are 5249's, at least |
| 19:21:47 | FiZZ | they are compatible, yeah yeah, but Im guessing that the h3xxs have some more extensions |
| 19:21:56 | preglow | what extensions would that be? |
| 19:21:56 | FiZZ | i dont think the xvid decoding is a piece of cake |
| 19:22:24 | preglow | well, no, but i don't think the cpu has any more facilities to ease it |
| 19:22:26 | FiZZ | but maybe thats the 10fps and 400kbit bandwith limit they have ;) |
| 19:22:38 | FiZZ | well |
| 19:22:38 | preglow | it's probably just very tight code |
| 19:22:46 | FiZZ | its definetly tight code ;) |
| 19:23:07 | FiZZ | im gonna take a look at the reverse engineered firmware some day |
| 19:23:14 | preglow | good luck |
| 19:23:29 | FiZZ | just curious about their assembly |
| 19:23:36 | preglow | i wonder if there's a 5249 optimizing guide around |
| 19:23:44 | preglow | i sure as hell could need one |
| 19:23:59 | FiZZ | hm |
| 19:24:48 | preglow | our codecs are shit slow at the moment |
| 19:24:52 | preglow | and need very extensive optimizing |
| 19:24:54 | FiZZ | what are you coding atm ? |
| 19:25:41 | preglow | i'm working on optimizing the codecs |
| 19:25:51 | FiZZ | oh i c |
| 19:26:13 | FiZZ | happy inverse discrete cosine transformations, eh ? ;) |
| 19:26:34 | preglow | yes, it'll be fun doing those in asm |
| 19:27:08 | FiZZ | is there any way to test without an actual h1xx ? |
| 19:27:38 | preglow | i am wondering about the same thing |
| 19:27:54 | preglow | there are coldfire simulators about, but none that support the 5249 extensions |
| 19:28:02 | preglow | which we'll rely pretty heavily on while optimizing |
| 19:28:41 | FiZZ | well i defenitely wanna aid u guys |
| 19:28:54 | FiZZ | but seeing that theres emulator issues and i just own a h3xx im kinda lost |
| 19:30:43 | CoCoLUS | do we have a 4 in a row plugin? :) |
| 19:30:55 | rasher | CoCoLUS: nope :) |
| 19:31:15 | preglow | FiZZ: you could work on finding an emulator :P |
| 19:31:40 | rasher | I'll be happy to test out code on my iRiver |
| 19:32:15 | FiZZ | hehe well |
| 19:32:36 | FiZZ | i can try. I can ask some of my profs |
| 19:32:44 | FiZZ | i think we had a project that involved a coldfire |
| 19:32:56 | FiZZ | but i dont think theres a GPL'd solution |
| 19:34:08 | preglow | FiZZ: http://www.rockbox.org/twiki/bin/view/Main/ColdfireEmulatorDevelopment |
| 19:36:03 | FiZZ | kk |
| 19:37:14 | FiZZ | hm that linked site doesnt show lots of progress :-/ |
| 19:37:58 | preglow | no, indeed |
| 19:38:12 | preglow | with just a bit of luck, it's abandoned |

| 19:42:01 | FiZZ | i c |
| 19:43:13 | LinusN | it's a simple parallel port wiggler from P&E |
| 19:43:37 | FiZZ | hm nice |
| 19:43:51 | FiZZ | i thought I read somewhere that some device was involved |
| 19:44:13 | LinusN | yes, the parallel port wiggler from P&E |
| 19:44:35 | FiZZ | lol |
| 19:44:42 | FiZZ | you got a point there |
| 19:44:46 | LinusN | :-) |
| 19:44:47 | FiZZ | how much are these things, roughly ? |
| 19:45:26 | LinusN | $200 something |
| 19:45:33 | FiZZ | meh |
| 19:45:54 | FiZZ | maybe i can trick the uni into buying one of these ;) |

| 19:48:09 | preglow | LinusN: didn't you say that thing managed to function also at 140 mhz? |
| 19:49:03 | LinusN | works for me |
| 19:49:07 | preglow | not bad for something parallel port based |
| 19:49:12 | FiZZ | thx for the info LinusN |
| 19:49:24 | LinusN | nah, it doesn't need to communicate in 140MHz |
| 19:49:45 | LinusN | the comm pace it set by the pc |
| 19:50:09 | preglow | ahh |
| 19:50:10 | LinusN | the only trick is that it has to handle the 140MHz clock when breaking the target |
| 19:50:29 | LinusN | and that is handled "locally" inside the wiggler |
| 19:50:50 | LinusN | i have to go now |

| 21:51:16 | elinenbe | HCl: what is the current rockboy speed? |
| 21:51:21 | HCl | elinenbe: too slow. |
| 21:51:34 | elinenbe | I know that, but is it still 1.5fps? |
| 21:51:39 | HCl | pretty much |
| 21:51:54 | HCl | dynarec is making the interpreter part slower |
| 21:52:14 | elinenbe | oh... that sucks... |
| 21:52:18 | HCl | but once it works, it should provide a deadly speed increase |
| 21:52:26 | elinenbe | what speed is the CPU running at on it? |
| 21:52:35 | preglow | same old, 11mhz |
| 21:52:37 | elinenbe | and what exactly is "deadly"? full speed? |

| 21:53:22 | HCl | its really a nightmare to debug |
| 21:53:29 | HCl | so that'll hold me back mostly |
| 21:55:16 | elinenbe | understandably... I can't imagine debugging a dynarec core... |
| 21:55:31 | elinenbe | Is it home-grown, or did you get it from somewhere? |
| 21:56:22 | pillo | question: in the viewers.config file, what are those numbers after the .rock file name? |
| 21:57:30 | preglow | pillo: an icon |

| 22:04:44 | pillo | HCl: I did that like 3 or 4" after installing rockbox for the first time ;) |
| 22:05:01 | pillo | I hated not seeing everything on the iriver firmware... |
| 22:05:39 | pillo | it lacked simply a reboot |
| 22:05:55 | pillo | the new .config was not parsed |
| 22:11:39 | elinenbe | HCl: what is the current status of the dynarec? |
| 22:11:43 | elinenbe | HCl: sounds good! |

| 23:51:33 | | Quit Tang ("Chatzilla 0.9.66 [Mozilla rv:1.7.5/20041108]") |
| 23:51:36 | linuxstb | Makes me wonder if there are better C compilers than gcc we could be using. |
| 23:51:50 | preglow | i really don't know, the code gcc makes doesn't seem to be half bad |
| 23:53:36 | preglow | but it surely makes you wonder |
| 23:54:02 | linuxstb | But he says that the JetAudio has the same CPU, but can only manage low order LPC. Which is similar to our performance - I think we may already be over 100% with FLAC for "easier" files. |
| 23:54:03 | rasher | so a lot of time is spent in FLAC__lpc_restore_signal ? |

| 23:54:43 | linuxstb | We haven't profiled it, but it seems the most "difficult" function. |
| 23:55:07 | preglow | i've already done some naive optimization for it |
| 23:55:14 | preglow | and it really didn't help much |
| 23:55:16 | linuxstb | It's also a function where there are a lot of existing ASM versions for other processors - so I assumed it would be a good place to start. |
| 23:57:51 | pillo | finally! |
| 23:58:00 | pillo | I've made viewer supporting proportional fonts properly. |
| 23:58:06 | preglow | great! |
| 23:58:47 | pillo | but I need to clean up the code before submitting the patch |
