| 00:00:03 | kugel | no |
| 00:00:54 | kugel | I also can't explain that. The only time I noticed a that slow UI on other targets was with caches disabled on my fuze, but you said they're definitely on |

| 00:03:12 | kugel | maybe you can implement led() (so that the disk access icon appears in the statusbar) to exclude excessive storage accesses |

| 00:05:32 | JdGordon| | TheSeven: slow ui scrolling could be slow lcd driver? or slow disk if it has to keep swapping out font glyphs? |
| 00:06:18 | TheSeven | JdGordon|: LCD is ~80-100FPS fullscreen RGB |
| 00:06:26 | TheSeven | quarter screen was around 300 |
| 00:06:39 | JdGordon| | its not that then :) |
| 00:06:51 | kugel | the font idea is good one, in fact that was another time I noticed slowish UI (I forget, some versions of the anti-aliased font patch caused huge slowdowns) |
| 00:06:53 | TheSeven | how big is that glyph cache? |
| 00:07:01 | TheSeven | storage is really a bottleneck on that one |
| 00:07:04 | JdGordon| | 100K i tinhk |
| 00:07:20 | JdGordon| | shuold be plenty big enough if your filenes are all english |
| 00:07:26 | JdGordon| | dircache enabled? |
| 00:07:37 | TheSeven | dircache doesn't seem to make any difference |
| 00:07:53 | TheSeven | (at least in the file browser) |
| 00:08:03 | TheSeven | but the plugin menu behaved very weird with dircache |
| 00:08:38 | | Quit bmbl ("Bye!") |
| 00:13:50 | kugel | still? |
| 00:16:16 | TheSeven | in fact the dircache slowed scrolling down as soon as i scrolled to regions where i hadn't been before |
| 00:16:23 | TheSeven | with dircache disabled, it's all fast |
| 00:16:42 | TheSeven | (well, as fast as the file browser at least) |
| 00:17:05 | kugel | I didn't have dirache on when I played around |
| 00:17:45 | TheSeven | well, with dircache on it was like half a second for every scrolling step |
| 00:18:10 | kugel | uh, that's really bad |
| 00:18:36 | kugel | it seems accessing ram is slow |
| 00:19:45 | TheSeven | no, accessing flash |
| 00:20:05 | kugel | well, you don't access flash if you have dircache on |
| 00:20:07 | TheSeven | or maybe non-builtin strings |
| 00:20:25 | TheSeven | all the builtin menus are just fine |

| 00:22:33 | kugel | so unless you actually access the content of files, you never actually hit the storage |
| 00:23:38 | kugel | i really recommend implementing the disk access indicator |

| 00:33:41 | datty | i would like to get into this dev stuff for my Fuze |
| 00:33:49 | TheSeven | neither does the length of the text nor the type of the line selector have any influence |
| 00:33:58 | datty | I have some experience with AVR/PIC stuff, is it pretty similar with ARM? |
| 00:34:28 | TheSeven | datty: ARM is more like a desktop CPU compared to those microcontrollers, but of course, the basics are the same |
| 00:34:37 | Torne | datty: a little. Almost all of rockbox is written in C, though, so the low level details of architecture are not too important for most things |
| 00:34:52 | datty | i do prefer C over asm anyday |
| 00:35:30 | Torne | if you can program in C and are familiar with concepts like memory mapped devices that's more or less all you need |
| 00:35:47 | TheSeven | kugel: interesting... runtime-generated debug menu contents aren't sluggish either |
| 00:35:53 | Torne | actually knowing arm/m68k/coldfire is not important unless you end up in very specific parts of the code |

| 00:36:07 | gevaerts | Guest24033: it means you have to reboot to the original firmware for USB |
| 00:36:40 | datty | i am used to AVR Studio and MPLAB, is there something similar with this? |
| 00:37:12 | Torne | No |
| 00:37:15 | datty | I see "get the source, build, and change (patch)" |
| 00:37:28 | Torne | Yes. You can use any editor/IDE you like.. |
| 00:37:56 | Torne | but a fully integrated system like AVR Studio is not really possible on platforms like DAPs where you have no code download or debug facilities |
| 00:37:59 | datty | i guess i mean more for in circuit debugging, is this even possible? |
| 00:38:03 | TheSeven | datty: but of course the funny part is that there is no proper on-target debugging functionality :-) |
| 00:38:10 | Torne | No, we basically have no on-target debugging |
| 00:38:12 | datty | oooh |
| 00:38:18 | Torne | A few platforms have a JTAG port, if you rip them open |
| 00:38:26 | Torne | and solder stuff tot he right place. |
| 00:38:27 | datty | then that makes things more difficult ;) |
| 00:38:30 | Torne | but most don't. |
| 00:38:39 | TheSeven | well, we have basic things like a log ring buffer, but nothing you could really call a debugger |
| 00:38:59 | Torne | datty: there's various ways of logging debug messages, either to a buffer or over serial/usb, depending on hardware |
| 00:39:06 | Torne | but that's basically all you get. no ICE/ICD |
| 00:39:28 | datty | hm |
| 00:39:39 | TheSeven | if we had ICD and proper datasheets, all those targets would be implemented in no time :-) |
| 00:39:43 | datty | I'm interested in somehow interfacing directly with the ARM, has anyone tried that |
| 00:39:50 | Torne | define "interfacing directly" |
| 00:39:56 | datty | TheSeven: yeah thats why I got interested ! |
| 00:39:58 | Torne | you mean with your mind, or what? :) |
| 00:40:09 | datty | i was thinkin man whats takin so long :) |
| 00:40:20 | datty | but yea its much harder |
| 00:40:25 | datty | interfacing directly with the pins |
| 00:40:32 | Torne | datty: yeah, all our porting is done based on what little docs are published, and on reverse engineering the orignal firmware, and general guessing :) |
| 00:40:36 | Torne | datty: er, to do what? |
| 00:40:44 | Torne | We're already running code on the chip |
| 00:40:49 | Torne | you can't really get more direct than that |
| 00:41:14 | datty | yea but i'm sure that ARM has a program for in circuit debugging, no? |
| 00:41:29 | datty | maybe my questions don't make sense, i've never worked on a device like this |
| 00:41:32 | Torne | ARMs are not sepearate chips |
| 00:41:34 | datty | so keep that in mind |
| 00:41:42 | Torne | They are synthesized into the middle of a system-on-chip |
| 00:41:46 | Torne | with peripherals and so on on the same die. |
| 00:41:57 | Torne | If the JTAG pins are not brought out onto the SoC's pins there's nothing you can do |
| 00:42:06 | TheSeven | datty: ARM maybe has, but this doesn't mean it's accessible anywhere on the board or even SOC package, and sometimes those things are even fused out during production |
| 00:42:07 | Torne | or equally, if they are brought out but not connected to tracks |
| 00:42:19 | Torne | and yes, sometimes they get disabled in the factory with efuses |
| 00:42:25 | datty | i see |
| 00:42:40 | datty | but ARM922TDMI is a separate chip right |
| 00:42:42 | Torne | No |
| 00:42:46 | Torne | There is no such thing as an ARM chip |
| 00:42:56 | Torne | They haven't made physical ARm processors for over a decade |
| 00:43:06 | TheSeven | Torne: or that funny thing we found on the nano2g, that the data bus shuts down until reset with the first jtag clock edge to prevent you from dumping the bootrom :-) |
| 00:43:26 | TheSeven | i bet there is a secret way to bypass this, but only apple knows how. |
| 00:43:35 | datty | apple?? |
| 00:43:43 | datty | o nano |
| 00:43:56 | Torne | datty: All ARM processors on hardware made since the mid-90s are just a macrocell inside a larger ASIC |
| 00:43:59 | TheSeven | well, probably apple, arm and samsung, in fact |
| 00:44:07 | Torne | datty: look up System-on-Chip on wikipedia :) |
| 00:44:14 | Torne | TheSeven: ARM are unlkely to know :) |
| 00:44:28 | Torne | they stay out of SoC vendors' business :) |
| 00:44:42 | datty | Torne: Ahhhh |
| 00:44:45 | datty | wikipedia is your friend |
| 00:45:13 | datty | so the SOC on the Fuze is proprietary SanDisk stuff? |
| 00:45:25 | Torne | No, it's a SoC mad by Austria Micro Systems |
| 00:45:32 | Torne | Hence AMS Sansa |
| 00:45:41 | datty | k |
| 00:45:41 | Torne | The DAP manufacturers don't generally design their own SoCs |
| 00:45:51 | Torne | but there are a dozen or more ARM SoC vendors |
| 00:46:02 | TheSeven | well, besides apple which seems to never have used a stock soc :-) |
| 00:46:07 | Torne | ARM only sell the intellectual property |

| 00:46:25 | | Quit LambdaCalculus37 (Read error: 145 (Connection timed out)) |
| 00:46:51 | datty | so i assume it's been looked into all methods of interfacing with the SOC besides the normal USB use? |
| 00:47:12 | Torne | People have generally looked for anything that's plausibly a JTAG port on our targets, yes |
| 00:47:16 | Torne | there's not really any method other than JTAG :) |
| 00:47:29 | Torne | there are a few with a known or suspected JTAG port. |
| 00:47:30 | datty | im curious how old are you people |
| 00:48:10 | Torne | 26, but if you wanna hang out and chat go to #rockbox-community :) |
| 00:48:12 | TheSeven | well, how old are you? I'm 19 years... |
| 00:48:28 | datty | i'm still a senior in undergrad so i have some exposure to this stuff but very limited |
| 00:48:49 | datty | oh ha not for a social reason just to get an idea of your knowledge-to-age ratio of sorts |
| 00:49:11 | datty | for example JTAG to me reminds me of the cable we used to program a Xilinx FPGA in one of my classes |
| 00:49:30 | Torne | datty: #rockbox is logged for people to review/search later, so we try to keep it to on-topic technical discussion |

| 00:52:37 | | Part datty |
| 00:52:39 | TheSeven | do you have any explanation as to why scrolling in the top-level database menu where you can select "artist", "album" etc. could be far slower than e.g. the main menu? |
| 00:53:12 | | Part toffe82 |
| 00:54:05 | JdGordon| | you mean verticle scrolling right? |
| 00:54:36 | JdGordon| | hang on... is the top level one any slower than going into any of the sub items? |
| 00:54:50 | kugel | TheSeven: all menu use the same code basis |
| 00:55:04 | JdGordon| | the database is not the menu :) |
| 00:55:21 | JdGordon| | it uses tagtree which i have no idea how it popuilates the list |
| 00:55:25 | TheSeven | no, it seems to be everything that contains runtime-generated strings, but for some reason also the database top-level menu |
| 00:55:48 | JdGordon| | runtime generated meaning translated? or? |

| 00:58:16 | TheSeven | (scrollable in terms of horizontal here) |
| 00:58:37 | JdGordon| | is there something wrong with your thread switching code maybe? |
| 00:58:54 | TheSeven | i don't think so, that's generic arm code, but of course it causes icache misses |
| 00:59:54 | JdGordon| | very curious indeed :p |
| 01:00 |
| 01:00:02 | TheSeven | hmm, no, there are horizontally scrolling menus, too, which are also fast |
| 01:01:15 | JdGordon| | the problem is slow resposne going up and down though? no problems if you arnt moving the selection? |
| 01:01:53 | TheSeven | well, if i aren't moving the selection there's nothing to judge on |
| 01:02:26 | TheSeven | but if you mean that i stay inside the visible range so that it doesn't need to scroll, that doesn't help |
| 01:02:44 | TheSeven | it even happens with menus that don't have enough entries to scroll at all, but in theory could have more |

| 02:08:22 | TheSeven | it's a function |
| 02:08:35 | TheSeven | but __attribute__((unused)) did the trick |
| 02:09:01 | kugel | you can also un-static it |
| 02:09:24 | TheSeven | well, it's local to that file, and has an ambiguous name in other contexts |
| 02:09:35 | kugel | interesting that gcc doesn't see it |
| 02:09:47 | TheSeven | gcc can't see it, as it's inline ASM |
| 02:09:51 | kugel | TheSeven: ______dma__callback then :D |
| 02:10:31 | TheSeven | ok, nice and green again |
| 02:11:18 | kugel | __attribute__((unused)) is probably the best way. in fact, I would like to see that used more instead of (void)foo all over the place |
| 02:11:50 | TheSeven | even though it's a little misleading, as it is in fact used :-) |
| 02:12:29 | TheSeven | ok, that was the last issue stopping us from boosting! |
| 02:14:13 | kugel | you could've also passed dma_callback as "parameter" the inline asm right? |
| 02:14:30 | TheSeven | my nano is just playing fine with an average ADC reading of 16mA, which is probably too high, as both the ADC and CPU are consuming more power than usual while the measurements are being done |

| 02:21:52 | Blue_Dude | TheSeven: you got it to work? Awesome! What did the trick? |
| 02:22:05 | TheSeven | splitting down the buffers even further |
| 02:22:21 | TheSeven | i couldn't use your idea because the PCM api in between wouldn't have let me |
| 02:22:34 | TheSeven | we always forget that there are also other audio sources than pcmbuf :-) |
| 02:22:54 | Blue_Dude | Whatever works. That's great. |
| 02:23:16 | TheSeven | right now, if i get passed a buffer that's at least 2048 bytes, i'll split off the last 1024 bytes |
| 02:23:28 | | Join Feanor_ [0] (n=Feanor_@84.164.49.126) |
| 02:23:36 | Blue_Dude | It's probably also a lot cleaner than hacking up pcmbuf for a single target. |
| 02:23:59 | TheSeven | this buffer will be requested while the last 1024 bytes of the buffer before are playing, and it will be started as soon as these are done |
| 02:24:25 | TheSeven | when the next DMA int comes in, i still have 1024 bytes which i can throw into the dma, while requesting the next one, and so on |
| 02:24:34 | Blue_Dude | So you roll your own prebuffer while callback is running. That's nifty. |
| 02:24:42 | TheSeven | and i doubt any codec will ever be able to overwrite these 1024 bytes fast enough... |
| 02:25:24 | TheSeven | (and even if it would, this would just end up in dcache and not hurt the DMA) |
| 02:26:37 | TheSeven | and of course the other part of that trick is an ASM FIQ handler that will setup the next DMA transfer within 4 instructions no matter what's going on |
| 02:27:19 | Blue_Dude | I dug some more into the low level pcm drivers this afternoon and I think it might have been possible to hack pcmbuf, but it wouldn't have been pretty. Doing it within your own black box is better though. |
| 02:27:47 | TheSeven | the only case that can hurt is if there are chunks < 2048 bytes, as these will be directly used as the "tail buffers", so the next one will be requested immediately, which may lead to codecs overwriting them ahead of time again, but this could possibly still be caught by dcache |
| 02:28:11 | | Quit DerPapst ("Leaving.") |
| 02:28:14 | TheSeven | (which is 4KB on that target) |
| 02:28:37 | Blue_Dude | What happens when the codec stops feeding data at the end of the playlist? You will get the tail end then. However, the codec won't be overwriting either. |
| 02:29:55 | | Quit peter-b (Read error: 145 (Connection timed out)) |
| 02:30:02 | TheSeven | this will just mean that the pcmbuf can't supply data while I'm playing the tail, so it will not schedule a new buffer for pushing to the dma, and as soon as the DMA of the tail finishes, it will realize there is nothing more to do and call that stop callback |
| 02:31:07 | TheSeven | linuxstb: we seem to have reached apple's battery runtime with some tricks :-) |
| 02:31:07 | Blue_Dude | OK, just so long as your prebuffer doesn't choke on a smaller than expected payload. That's just details though. Congratulations. |
| 02:31:27 | linuxstb | TheSeven: Nice. Is battery_bench working now? |
| 02:31:44 | TheSeven | linuxstb: it's failing every night because of a new reason |
| 02:32:06 | TheSeven | Blue_Dude: it shouldn't choke on that, as it's able to chain tails directly if they're too small to split them |
| 02:33:00 | Blue_Dude | TheSeven: that's excellent. |
| 02:33:06 | TheSeven | this ranges from FTL problems to stack overflows to whatever |
| 02:33:24 | TheSeven | I won't do it tonight because my battery isn't really full right now |
| 02:33:42 | TheSeven | but i'll post the patch to flyspray right away |
| 02:43:22 | TheSeven | FS #10714 |
| 02:44:33 | TheSeven | Blue_Dude: BTW I spotted two things that look like bugs in pcmbuf: |
| 02:45:37 | TheSeven | line 1029: The actual buffer usage is higher than that, as some date (which isn't included in that value) may still be playing |
| 02:45:48 | Blue_Dude | TheSeven: that doesn't surprise me at all. |
| 02:46:08 | TheSeven | and line 1041: I don't see what this is supposed to do. Looks like someone copy-pasted something in the wrong place. |
| 02:46:31 | TheSeven | why for heaven's sake does it divide a percentage value by pcmbuf_unplayed_bytes? |
| 02:47:00 | TheSeven | shouldn't that be pcmbuf_size? |
| 02:47:01 | Blue_Dude | re line 1029: that's pretty approximate because it doesn't include pcm_unplayed_bytes or whatever it is from pcm.c |
| 02:48:49 | Blue_Dude | re line 1041: you're probably right. I'm not 100% sure where those functions are called from, but they smell like debug screen info to me |

| 02:51:12 | *** | Saving seen data "./dancer.seen" |
| 02:53:42 | Blue_Dude | re line 1029: the problem is that pcmbuf_unplayed_bytes is decremented as soon as the chunk is sent to the DMA, not when it's played. If you want to be really accurate, you'd have to keep add last_chunksize to pcmbuf_unplayed_bytes. That assumes that the entire chunk is off limits whether part of it has been played or not, which is safest. |
| 02:54:22 | TheSeven | depends on what this function is good for |
| 02:54:52 | TheSeven | this could either be space used in terms of allocated/locked, or in terms of data being in the buffer ready to be retrieved |
| 02:54:59 | Blue_Dude | As I said, it smells like howgozit info vs. operational necessity. |
| 02:55:37 | Blue_Dude | If you're looking for free buffer space, you have to assume that the currently playing chunk is not free though. |
| 02:55:37 | TheSeven | btw, that pcmbuf_mix_free is only used by pcmbuf itself |
| 02:55:52 | Blue_Dude | Figures. |
| 02:56:26 | TheSeven | the same is true for the other one |
| 02:56:43 | TheSeven | and it's both on line 882 |
| 02:56:57 | TheSeven | "A get-it-to-work-for-now hack" :-) |

| 02:57:15 | Blue_Dude | Yeah, that's right. :) |

| 11:55:56 | Paprica | my "making" look like that |
| 11:55:57 | Paprica | http://pastebin.com/d5e5cfe2a |
| 11:56:10 | Paprica | what i need to do? |
| 11:57:21 | n1s | configure should turn that warning off, it's basically harmless; are you using a recomended compiler version? |
| 11:59:12 | Paprica | good question i dont know the answer XD i just follow the instructions here http://www.rockbox.org/wiki/LinuxSimpleGuideToCompiling |
| 11:59:26 | n1s | or did you run configure without the compiler in the path maybe? if so rerun configure |
| 12:00 |
| 12:00:21 | Paprica | i did conigure |
| 12:01:41 | n1s | configure should tell you if it can't find the compiler |
| 12:02:05 | TheSeven | n1s: this looks like there is another arm-elf-gcc it found that isn't ours |
| 12:02:25 | Paprica | TheSeven what should i do? |
| 12:02:39 | TheSeven | put the right one to the path |
| 12:02:57 | TheSeven | what does a "which arm-elf-gcc" result in? |
| 12:04:09 | Paprica | ./usr/local/arm-elf/bin/arm-elf-gcc |
| 12:04:34 | TheSeven | looks sane |
| 12:04:59 | Paprica | so? :\ |
| 12:05:05 | TheSeven | arm-elf-gcc −−version |

| 12:06:05 | n1s | TheSeven: yeah |
| 12:06:08 | n1s | it can also happen if you un confgure without the right crosscompiler in the path as it then can't determine the version and make the choices about disabling warnings etc. |
| 12:06:23 | TheSeven | and another thing you can check: ls -l /usr/local/arm-elf/bin/arm-elf-gcc |
| 12:06:33 | TheSeven | does that show the date you ran rockboxdev.sh? |

| 12:09:44 | TheSeven | ok, so the right compiler is in the path |
| 12:10:28 | Paprica | seem to be ok :) |
| 12:10:31 | Paprica | thank you :P |
| 12:11:57 | TheSeven | ok, so the first quess was right: [11:58]<n1s>or did you run configure without the compiler in the path maybe? if so rerun configure |
| 12:12:58 | n1s | TheSeven: the fun thing is that configure prints a big warning when you run it without the compiler in the PATH... |
| 12:13:44 | n1s | also, slightly related; i wonder if it would make sense to fix those pointer signedness mismatches |
| 12:14:38 | TheSeven | yes, I wondered about that, too |
| 12:15:01 | TheSeven | while most of them probably can't, some of them may be potentially harmful |

| 12:28:30 | TheSeven | when did this start to happen? |
| 12:30:03 | TheSeven | can somebody else have a look at config.h:775 and see if I'm just blind or this is really just confusing nonsense that's being done there? |
| 12:30:32 | Utchybann | I just compile r23328 and try to play elephantdream video (from rockbox site). |
| 12:31:18 | TheSeven | how does the sound behave? squirrel mode? or just skipping? |
| 12:32:41 | Utchybann | squirrel mode? It is like play the video at 100fps. |

| 13:01:28 | * | TheSeven also just realized that mutexes aren't interrupt-safe |
| 13:03:06 | bertrik | no, I think you can't use a mutex at all in interrupt context |
| 13:03:36 | TheSeven | but they are being used in an interrupt context |
| 13:03:43 | bertrik | you can post a message in a queue, but that's basically the only kernel primitive you can call, I think |
| 13:03:58 | TheSeven | ...and hopefully wakeups |
| 13:04:08 | bertrik | yeah, those too :) |
| 13:04:43 | funman | mutexes are used in interrupt context ? |
| 13:04:45 | amiconn | You can't block on a mutex in interrupt context, that would cause a freeze if it actually blocks |
| 13:05:14 | TheSeven | of course, and I'm currently trying to track down a place where this happens |
| 13:05:35 | bertrik | We should have some way to panic on that I think |
| 13:05:37 | amiconn | This is obvious - the thread holding the mutex can't let it go because it won't execute unless the isr returns, which it can't do because of the block |
| 13:05:44 | amiconn | This is by design |
| 13:06:09 | funman | bertrik: how we know if we're in an isr is platform dependant |
| 13:06:34 | amiconn | Why would we need a panic for this? |
| 13:06:35 | bertrik | great, so we can implement it for some platforms :) |
| 13:07:03 | kugel | the comment makes me wonder why NOCACHEBSS_ATTR is only defined for PP |
| 13:07:08 | funman | well we can check the cpsr for interrupt state |
| 13:07:29 | amiconn | funman: Coldfire, SH1, MIPS, ... |
| 13:07:43 | funman | TheSeven: what about printing the current stack if such a thing happen and look for addresses ? |
| 13:07:55 | funman | amiconn: yeah it's platform dependant, but this could help TheSeven on nano2g |

| 13:10:39 | TheSeven | bertrik: there already is a flag for that, but it's barely used |
| 13:11:04 | funman | DEBUG ? |
| 13:11:11 | amiconn | I guess it depends on how expensive that check is |
| 13:11:32 | TheSeven | funman: no, there's something specific for the kernel |
| 13:12:11 | bertrik | DEBUG enables KERNEL_OBJECT_CHECKS |
| 13:15:02 | bertrik | amiconn, what do you think? Would you approve of extra checking in the kernel (#ifdef DEBUG or similar) that verify if a call is made in the right context? |

| 20:27:15 | BBB | saratoga, how diff is wmafixed from wmafloat/ffmpeg? |
| 20:27:38 | saratoga | most of the basic functions are similar, and it has been back ported to ffmpeg based projects |
| 20:27:55 | funman | some tables/functions are given section attributes to be put in faster memory |
| 20:28:57 | saratoga | we use a different mdct now, and the decode_superframe function has been split into a function that works on smaller pieces (the original wma codec could operate on enormous blocks of memory at one time IIRC) |
| 20:29:56 | saratoga | we also don't use the ffmpeg parser |
| 20:29:59 | saratoga | asf parser |
| 20:30:06 | BBB | saratoga, can you submit the superframe decode function split? that would help |
| 20:30:09 | BBB | it's a big ugly function |
| 20:30:10 | BBB | :) |
| 20:30:22 | BBB | the fact tha tyou don't use asfdec shouldn't matter much right? |
| 20:30:50 | saratoga | linuxstb wrote it originally IIRC, but I think it shouldn't be too hard to port |
| 20:31:02 | saratoga | although i'm not sure if the ffmpeg API would be ok with it |
| 20:33:28 | saratoga | i'd have to review the change, but I suppose wma_decode_superframe could be replaced with wma_decode_superframe_frame (e.g. the version that returns exactly 2048 samples) and be made to call wma_decode_superframe_init everytime it finished a superframe |
| 20:35:06 | BBB | could you submit patches for that? |
| 20:36:37 | saratoga | eventually, but i have little time during the semester |
| 20:36:52 | saratoga | why the new interest in our wma changes? |
| 20:37:33 | saratoga | funman: unrelated question, what does it mean when the clip crashes by simply powering down, and reboots on any button press at all (not just power)? |
| 20:38:00 | funman | I'd say panic |
| 20:38:12 | funman | panicf() will reboot on any button press |
| 20:39:06 | saratoga | shouldn't that print an error? |
| 20:39:36 | | Quit Vitor1001 (Read error: 110 (Connection timed out)) |
| 20:40:13 | petur | it should print stuff and reboot if you hit a key in that screen |
| 20:41:33 | funman | saratoga: i've seen unexplained reboots already, how can i reproduce this one ? |
| 20:42:24 | saratoga | funman: I get them pretty easily with this patched clip build: http://duke.edu/~mgg6/rockbox/rockbox_move_handle_v1.7z |
| 20:42:41 | saratoga | takes maybe 1-2 tracks before it randomly happens while playing |
| 20:42:50 | saratoga | its just the latest buffering patch |
| 20:42:54 | saratoga | i'm a little confused whats happening |
| 20:42:58 | funman | do you have lcd always on |
| 20:42:59 | kugel | saratoga: is the display off so that you can't read the screen? |
| 20:43:20 | saratoga | kugel: theres a click sound like the DAC powered off, but its possible the rest of the SOC is still on |
| 20:44:10 | kugel | it sounds like a panicf to me too, you of course need the display on in order to read it |
| 20:45:45 | funman | if kugel and me agree it surely must be the Truth ;)) |

| 22:14:39 | GeekShado_ | I hope your work willl work on M3 hardware too |
| 22:15:22 | bertrik | GeekShado_, the meizu m3 already has a working display, the m3 probably benefits most from the things that TheSeven is currently doing |
| 22:15:38 | GeekShado_ | oh cool |
| 22:17:34 | TheSeven | my nano has a current leak o.O |
| 22:18:06 | AlexP | TheSeven: At least it isn't a currant leak :) |
| 22:18:23 | TheSeven | as soon as i disable the USB controller once (and disable it again), power consumption more than doubles |
| 22:18:44 | TheSeven | I checked the USB powerdown code, and it seems to be right (and clocks are properly getting masked etc.) |
| 22:19:34 | bertrik | it's a really useful feature to have an adc for measuring current consumption :) |
| 22:19:48 | | Part j-b |
| 22:20:05 | TheSeven | measuring it with a multimeter would in fact be better, but I can't reach the battery in that thing without destroying it |
| 22:20:52 | TheSeven | but yes, this *would* be pretty useful for things like battery runtime estimation code, if rockbox would support it :-/ |
| 22:21:36 | kugel | you can make rockbox support it! :) |
| 22:21:56 | bertrik | oh I thought rockbox already did have a battery_current function or something similar |
| 22:22:12 | TheSeven | yes, but it's quite hardwired to |
| 22:22:12 | bertrik | (and using it for battery estimation) |
| 22:22:21 | TheSeven | *estimating* the current rather than measuring it |
| 22:22:43 | kugel | I think the estimation is actually taking the current into account, it's just that most/all assume a (compile-time) constant value |
| 22:23:50 | n1s | likely many older targets couldn't measure the current so rockbox never got the ability to support esimation based on measurment |
| 22:24:29 | kugel | that's a reasonable assumption ;p |
| 22:28:02 | bertrik | the meizu m6 sp display is currently in portrait mode, rather than landscape as it's used in the OF. I hope to find out more about the LCD to change this. |

| 22:41:19 | Davide-NYC | Hello all. I'm having big problems with a recent RB upgrade. |
| 22:41:40 | saratoga | TheSeven: should be farely easy to make runtime estimation use the current meter on the 2G |
| 22:42:05 | saratoga | but i wonder how useful it'll really be, at least with a compile time value we know the value chosen is an average over an entire battery bench |
| 22:42:05 | Davide-NYC | On my H120-RTC-CFMod target I get codec and encoder errors as well as incompatible version. I've done clean installs (deleting .rockbox prior to unpack) |
| 22:42:11 | Davide-NYC | any ideas? |
| 22:42:23 | saratoga | i think if you watch it in real time you may get a lot of jumping around as the bit rate changes and such |
| 22:42:53 | saratoga | though i suppose with a long enough running average it might work pretty well |
| 22:42:55 | Davide-NYC | Compiling in cygwin. reproduced problem on two different (although similarly modded) units. |
| 22:46:37 | TheSeven | how can modifying system_exception_wait make it crash on boot, reproducibly? |
| 22:48:20 | TheSeven | ok, what should i fix/break next? :-) |
| 22:50:47 | n1s | Davide-NYC: you don't runa rockbox from flash, do you? |
| 22:50:47 | * | TheSeven is about to file a flyspray bug regarding flyspray being unable to search for all bugs affecting a certain target |
| 22:50:48 | Davide-NYC | Doh! I think I figured it out. I forgot to flash my RAM/ROM |
| 22:50:53 | n1s | run, even |
| 22:51:25 | Davide-NYC | n1s: exactly my prblem, but I just formatted my CF and am compiling my code (again) so in a minute we'll see. |
| 22:51:39 | *** | Saving seen data "./dancer.seen" |
| 22:51:48 | saratoga | running from flash if you have a CF card probably isn't worth the hassel |
| 22:51:50 | n1s | that is likely the problem |
| 22:51:54 | Davide-NYC | I just forgot the flashing step so everything on the CF itself was truly incompatible |
| 22:52:54 | Davide-NYC | saratoga: I'm not sure booting from CF is supported by bootloader v7pre4 |
| 22:54:14 | n1s | Davide-NYC: there is some kind of way to boot from the hd with that bootloader that you need to use anyway if you want to flash IIRC |
| 22:54:37 | n1s | but i think that is new enough to have the cf fixes |
| 22:55:44 | Davide-NYC | any news on a final V7 release for that bootloader? |
| 22:56:49 | * | TheSeven wonders if it's worth a try to dig into all that UI stuff to track down what's going on with nano2g scrolling |

| 23:00:08 | Davide-NYC | saratoga: booting from CF (HD) works perfectly. |
| 23:03:10 | saratoga | anyone feel like trying out a clip build and letting me know the abort address when it crashes? |
| 23:04:54 | * | amiconn returns |
| 23:05:43 | amiconn | kugel: At the time you linked to you only said that you experimented a bit, but there are no results given |
| 23:05:58 | amiconn | Did you measure the potential speedup meanwhile? |
| 23:06:23 | kugel | amiconn: well, I asked you if you saw it. if you said no I would've shown you some results |
| 23:06:33 | * | amiconn also wonders whether it'd matter in real-world figures at all |
| 23:07:27 | bertrik | amiconn, I'm reading a datasheet right now that indicates that it should indeed be possible to change the portrait/landscape mode for some targets, I'll try that now (bit 3 in R03h - Entry mode) |
| 23:07:33 | kugel | http://www.rockbox.org/irc/log-20091020#01:55:13 - basically 10% speedup on my fuze, <5% on my e200 |
| 23:07:49 | kugel | the results are further down |
| 23:08:09 | kugel | starting at 2:45 |
| 23:10:15 | amiconn | hmm |
| 23:10:46 | amiconn | I still wonder how important it is. The usb screen is one of the rare cases that uses transparent bitmap drawing for a large bitmap, isn't it? |
| 23:11:00 | amiconn | Also, is the asm function smaller or larger than the C equivalent? |
| 23:12:52 | kugel | I didn't messure binsize if you mean that |
| 23:13:11 | bertrik | aw, the landscape/portrait swap didn't work .. |
| 23:13:36 | amiconn | I do mean that |
| 23:13:57 | amiconn | The place where this function resides currently is odd. |
| 23:14:03 | | Quit polobricolo (Read error: 110 (Connection timed out)) |
| 23:14:05 | kugel | the inline assembly is only 15 lines, it doesn't make a difference anyway |
| 23:14:28 | kugel | if we have it already we can use it for all (applicable) targets IMO |
| 23:15:09 | | Quit tomers (Read error: 60 (Operation timed out)) |
| 23:15:10 | * | amiconn thinks this could be sped up even further, at least on ARMv6 (beast) |

| 23:17:28 | | Quit n1s ("Lämnar") |
| 23:17:35 | kugel | it has a tad bit different clipping and doesn't calculate dst_end, I wonder what code to keep (apart from the asm) |
| 23:19:00 | | Join faemir [0] (n=faemir@78.33.109.163) |
| 23:21:01 | amiconn | The C code needs to stay anyway, for the sims and the other archs |
| 23:21:08 | kugel | sure |
| 23:21:27 | kugel | I mean the code outside the loop |
| 23:24:19 | Davide-NYC | Comment about iRiver bootloader v7pre4: On CFModded H1x0 targets USB disk mode does not work for all CFCards. Neither does booting from CFCard (for probably the same as of yet unknown reason). |
| 23:24:56 | amiconn | The C code isn't very efficient |
| 23:25:33 | * | amiconn guesses that if the inner loop in the C code is optimised, it will be as fast as the asm, with the added benefit that it'd also speed up things on the other archs |
| 23:27:07 | amiconn | In fact I guess that if this gets optimised, the compiled arm code will look very similar, if not identical, to the asm version |
| 23:29:09 | kugel | that wouldn't surprise me |

| 23:33:17 | kugel | amiconn: so what now? |
| 23:33:55 | amiconn | Imo optimising the C would be the best solution |
| 23:34:31 | amiconn | Less ifdef,s and more targets benefit from that |
| 23:35:52 | kugel | I don't think I'm able to optimize it to be as fast, I could try the count-towards zero thing (but that might actually be sufficient already) but I don't see much more |
| 23:36:35 | amiconn | The inner loop is a for loop atm. That's not the best choice speed wise |
| 23:36:42 | Davide-NYC | I just compiled a patched bootloader from FS #9642, I'm expecting a file called "bootloader.iriver" but instead I have a bootloader.bin file. Are these the same file? |
| 23:36:48 | * | amiconn might have a shot at it tomorrow |
| 23:37:35 | Davide-NYC | Guys, I'm going to be flashing my bootloader and do not want to brink my beloved H1120+mods. Am I doing this correctly? |
| 23:38:23 | AlexP | I wouldn't be flashing an untested H100 bootloader if it were me |
| 23:38:44 | Davide-NYC | AlexP: can you take a look at FS #9642? |
| 23:39:15 | Davide-NYC | I mean, I've gotten a lot of good use out of RB and *somebody* has to test this patch. |
| 23:39:38 | AlexP | Davide-NYC: I'm not testing any H100 bootloader patches |
| 23:39:53 | AlexP | Davide-NYC: I have no way of recovering if it is not good |
| 23:40:25 | * | TheSeven wonders how that bootloader was developed then |
| 23:40:27 | saratoga | someone with a BDM cable should test it so that they can unbrick if needed |
| 23:40:34 | AlexP | yep |
| 23:40:51 | AlexP | TheSeven: By linusn who has a BDM wiggler |
| 23:40:51 | Davide-NYC | No, I'm willing to do it, since I have a spare unit. I was just asking that you look at the patch since I'm not very good at coding and there is a persistent bug in the BL as is. |
| 23:41:08 | AlexP | Davide-NYC: I'm not the person to be commenting on the code :) |
| 23:41:18 | Davide-NYC | OK |
| 23:41:36 | AlexP | I could, but it'd be meaningless :) |
| 23:42:37 | Davide-NYC | Question remains: Is bootloader.bin == bootloader.iriver? (presuming I've configured correctly? |
| 23:43:08 | AlexP | TheSeven: The H100 and H300 bootloaders are a bit of a bugger - they need thorough testing by someone who can recover in the event of problems before release, and this person is LinusN (who is busy and not around much these days). That means that they don't tend to get updated |
| 23:43:41 | AlexP | Davide-NYC: One mo |
| 23:46:47 | | Quit dmb ("Leaving") |
| 23:48:52 | AlexP | Davide-NYC: Sorry, not sure. I was looking something up but couldn't find it |
| 23:49:39 | Davide-NYC | me neither :( |
| 23:51:42 | Davide-NYC | I just tried to flash the bootloader.bin file and the iriverflash utility gave an "unkown filetype" error. |
| 23:51:48 | TheSeven | guessing from the name, it may need to be run though scramble, but honestly I have no idea about that target |

| 23:54:33 | Slasheri | rockbox.iriver is the bootloader.iriver |
| 23:54:39 | Slasheri | (when compiling bootloader) |
| 23:54:41 | Davide-NYC | How do I "make" that? |
| 23:54:54 | Slasheri | you should already have it, if you compiled the bootloader |
| 23:55:09 | saratoga | how trustworthy are data abort addresses on AMS? |
| 23:55:35 | Slasheri | but in order to flash it, you need to override safety mechanism from iriver_flash.c utility (or add then checksum of the new file there) |
| 23:55:35 | Davide-NYC | Slasheri: Got it. |
| 23:55:43 | * | TheSeven tries to get grip on the GUI code and terribly fails... |
| 23:56:34 | saratoga | if i have the address can I disassemble and find the exact line or is it only approximate? |
