| 00:14:34 | AlexP | cool |
| 00:15:23 | Torne | it's not very friendly to look at at the moment though because that is 133 branch heads |
| 00:15:32 | Torne | since svn tags are also treated as branches |
| 00:15:45 | Torne | and, er, a bunch of virtual branches for where we have done weird shit with svn is also treated as branches. :) |
| 00:16:04 | AlexP | clean-upable? |
| 00:16:08 | Torne | Yes |
| 00:16:16 | Torne | those are all under refs/remotes |
| 00:16:27 | Torne | we will discard all those refs once we stop needing to update from svn |

| 00:17:02 | Torne | but quite a lot of these branches have no content |
| 00:17:15 | Torne | and i can always put the old ones somewhere that clone won't bother cloning them by default |

| 10:30:13 | wodz | pamaury: can you point me out how usb drivers in rb works? |
| 10:30:40 | wodz | is there any documentation how to write usb driver? |
| 10:31:05 | kugelp | The Code |
| 10:31:11 | pamaury | wodz: sure, not really |
| 10:31:37 | pamaury | there are two different matters, both are very important: 1) usb detection 2) usb driver itself |
| 10:32:05 | wodz | usb detection is easy - the core sets the flag when usb connect occures |
| 10:33:12 | bertrik | I think there's also a separation in high-level more-or-less-generic "USB" code (e.g. the USB HID and MSC) and driver level USB code (to drive a specific USB controller) |
| 10:33:14 | TheLemonMan | wodz, what do you mean with how cache performs ? |
| 10:33:37 | wodz | see jhMikeS question |
| 10:34:04 | pamaury | of, the tricky part with usb detection is to make the whole machine work, it's a bit messy; for the usb driver |
| 10:34:12 | pamaury | you need to implement these functions: |
| 10:34:30 | pamaury | usb_drv_init -> one time init (once per connection); so basically enable the usb core |
| 10:34:45 | pamaury | (and boost if needed, very important on some !) |
| 10:34:53 | pamaury | usb_drv_exit -> the oppositze |
| 10:35:28 | pamaury | usb_drv_port_speed -> return the port speed, I don't remember the value but basically it's 0=full speed, 1=high speed or the converse |
| 10:35:42 | TheLemonMan | oh, usually the best combination is code in IRAM along with the most frequently used data |
| 10:36:20 | pamaury | usb_drv_request_endpoint -> reserve a endpoint; have a look at how other drivers to it; usually this is some administrative stuff + bit stuffing in the usb controller to set the type and max packet size |
| 10:36:24 | wodz | TheLemonMan: thats obvious the question is whats more important on ingenics as Iram is tight |
| 10:36:38 | pamaury | usb_drv_release_endpoint -> converse |
| 10:37:17 | wodz | pamaury: we reserve Control endpoint bulkin, bulkout |
| 10:37:23 | wodz | pamaury, something else? |
| 10:37:33 | pamaury | we don't reserve control |
| 10:37:35 | jhMikeS | I can get it to build if I take the mixer callback out of IRAM. all the loops are fairly small. there's probably junk in pcmbuf.c that is pointless to have in IRAM anyway as well. |
| 10:37:37 | pamaury | it's EP0, always |
| 10:37:57 | pamaury | it is never reserved, so don't alloc it to other drivers ;) |
| 10:38:09 | pamaury | we reserve bulk in/out, int in |
| 10:38:58 | pamaury | usb_drv_cancel_all_transfers -> kill all transfers; usually you need to set a bit for each endpoint and flush fifos. You should also call the completion handler with error status for everything |
| 10:39:17 | pamaury | usb_drv_recv -> setup a receive transfer; *non blocking* |
| 10:39:35 | pamaury | usb_drv_send setup a send transfer, *blocking* |
| 10:39:45 | pamaury | usb_drv_send_nonblocking -> "", *non blocking* |
| 10:40:12 | pamaury | usb_drv_set_test_mode -> set test mode, you can forget that for now, usually it's sufficient to bit copy the argument into some register of the controller |
| 10:41:41 | pamaury | usb_drv_set_address -> set the address (usually it's in a register); there is a problem here: some controller want the address to be set between control out and ack and some want to wait for the end of the transaction. In the first case, you need to write some code special code when getting setup packets and ignore this function (have a look at other drives) |

| 10:46:31 | max131 | Has the AMSv2 USB code been merged in rockbox already? I've got a patched version running r29857 now on my FuzeV2, and i was wondering if i still need to do patching on the current code base. |
| 10:46:32 | jhMikeS | TheLemonMan: it has no I-cache? the code execution is far more coherent because of small loops than the data |
| 10:47:16 | wodz | jhMikeS: google says it has 16kB I-cache and 16kB d-cache |
| 10:47:29 | TheLemonMan | it has separate D/I-cache so coherency isn't assured |
| 10:47:37 | pamaury | the amsv2 code doesn't work reliably |
| 10:48:12 | pamaury | max131: which patch ? |
| 10:50:51 | max131 | if i remember well i applied both as3525v2-enable-usb.diff and as3525v2-usb.diff |
| 10:51:49 | max131 | never tried the usb-pio.diff though |
| 10:52:02 | jhMikeS | TheLemonMan: I meant that the cached code is used over and over in a loop while the data would miss more often since it's way larger than 16KB. The ARM targets with separate I/D cache don't need much or any IRAM assistance with mixing. |
| 10:53:37 | pamaury | the as3525v2-usb.diff is perhaps not necessary (it's a hacky workaround), the other one is needed to enable usb |
| 10:53:56 | | Quit wodz (Quit: Leaving) |
| 10:55:57 | TheLemonMan | if all the data is used into the looping code then it's a problem |
| 10:56:03 | max131 | @pamaury, when you say the amsv2 code doesn't work reliably, do you mean the stock rockbox code, without any patch applied? |
| 10:56:31 | n1s | max131: the patch just enables the usb code already in svn |
| 10:56:41 | pamaury | the stock have it disable but with the patches it's unreliable; it works for some, doesn't work for others |
| 10:56:44 | n1s | it doesn't work reliably on all players |
| 10:57:09 | max131 | ok, happy to hear that code is checked in in svn |
| 10:57:10 | TheLemonMan | but if just a small part is accessed really often it's better to cache that to avoid frequent misses |
| 10:57:13 | jhMikeS | meh, there's no room on MIPS to be picky anyway |
| 10:58:00 | max131 | and it seems i'm a lucky guy because USB is pretty stable on my FuzeV2 |
| 10:58:28 | jhMikeS | max131: me too :) |
| 10:59:17 | max131 | so is it in autoconf.h that i have to enable USB for the FuzeV2? |
| 11:00 |
| 11:00:00 | pamaury | no, the enable-usb.diff patch is the right way to enable usb |

| 11:22:52 | jhMikeS | [Saint]: Meaning what exactly? |
| 11:24:30 | jhMikeS | I'd expect it could be acting much like the sim did initially |
| 11:24:37 | [Saint] | it's very choppy. |
| 11:24:50 | [Saint] | like it's cutting in/out many, many times a second |
| 11:25:25 | jhMikeS | sound like the same problem because it's not actually mixing at a steady rate |
| 11:25:31 | [Saint] | and that's not even with audio playing |
| 11:26:55 | jhMikeS | yep, that won't change it. it needs to be paced out in the main pcm callback |
| 11:29:00 | jhMikeS | voice decoding buffer latency is only about .06 seconds |

| 12:08:21 | pamaury | TheLemonMan: perhaps try the one I wrote for rockbox ? It might be that the freescale one make some assumption... |
| 12:08:46 | TheLemonMan | does it take the same database format as the official one ? |

| 12:10:01 | TheLemonMan | not really, i never had working code on that |

| 12:12:37 | pamaury | but it successfully send the code... |
| 12:13:16 | amiconn | jhMikeS: Btw, main lcd framebuffer is exactly the same size on both (0x140c bytes) |
| 12:16:00 | pamaury | TheLemonMan: does your custom code uses the ocram ? |
| 12:16:30 | TheLemonMan | yep |
| 12:16:42 | pamaury | I think the ROM has a limitation: it uses the upper part of the ocram for itself and leaves the lower part for the custom code |
| 12:17:30 | TheLemonMan | the official nand booter is rebased at 0 too so dont think it's a space limitation |
| 12:18:38 | pamaury | I mean, the ocram is 32kb (confirm ?), and the bootloader uses the higher 16kb so you shouldn't load more than 16kb to ocram at address 0 with the sb file |

| 13:00 |
| 13:00:11 | jhMikeS | n1s: the principle increase is 2k for the mixdown double buffer, which can have a smaller size at the expense of more interrupts |
| 13:01:53 | n1s | there seems to be a *lot* of lcd code in iram i wonder how much that actually gains |
| 13:03:46 | n1s | looks like ~4.8k for all the lcd_* functions in icode |

| 13:18:03 | GodEater | what on earth have we done to manage that? |
| 13:18:13 | Torne | well, themes and translate are entirely seperate histories |
| 13:18:21 | Torne | so there's going to be at least three. |
| 13:18:27 | GodEater | www? |
| 13:18:33 | Torne | www is actually branched from inside trunk |
| 13:18:39 | Torne | since it used to be a subdirectory |
| 13:18:46 | n1s | jhMikeS: yeah, i think only pixelma has an m5 though |
| 13:18:48 | Torne | this means the root there is trunk/www, not www |
| 13:18:57 | Torne | and that history includes duplicate copies of all commits that touched trunk/www before the split. |
| 13:19:01 | Torne | which is fun. |
| 13:19:11 | Torne | as it means therea re multiple git commits with the same svn revision number :) |
| 13:19:24 | Torne | likewise for songdbj |
| 13:19:43 | Torne | and then the same thing happens a couple more times possibly by accident where people have sometimes branched only subtrees of trunk for rbutil/bootloaders/etc |
| 13:20:05 | Torne | some of this will go away when i push stuff to seperate repos, but the bootloaders/rbutil subtree branches are.. interesting. |
| 13:25:02 | jhMikeS | n1s: ok, then who cares if it works any more :P |
| 13:25:20 | n1s | i bet she does :) |
| 13:26:19 | jhMikeS | exactly |
| 13:29:44 | jhMikeS | of course I can only test what I have and infer from that if there's an impact |
| 13:32:35 | amiconn | n1s: If you can make sure that all plugins use it from the main thread *only*, they could be on stack. Otherwise they wouldn't be in iram |

| 13:47:31 | kugel | Torne: I wonder why svn tags don't translate to git tags? |
| 13:47:42 | Torne | kugel: because svn tags are normal commits and thus can contain diffs |
| 13:47:52 | Torne | And quite a few of our old ones *do* contain diffs :) |
| 13:48:07 | AlexandrosSchill | Don't worry I won't mess around. I'll fix a few missing links that I found when I was researching putting rockbox on my fuzev2 |
| 13:48:22 | Torne | some because people were "naughty" and some because the git conversion handles tagging only a subdirectory interestingly |
| 13:48:27 | kugel | Torne: oh, that sucks balls |

| 13:49:35 | Torne | Different things were done differently. |
| 13:49:39 | Torne | it's not a problem, seriously. |
| 13:49:53 | Torne | The things that have diffs can also become git tags, the branch is not required |
| 13:50:03 | Torne | the existence of the tag keeps the commit reachable even if no branch head points to it |
| 13:50:16 | Torne | it just looks slightly odd in a history graph, but only if youa ctually bother to look back that far. |
| 13:51:12 | Torne | I'm probably going to keep all the old tags and branches just for historical reference but will put them in refs/oldheads or similar |
| 13:51:26 | Torne | which will mean git clone won't bother to fetch them by default and thus you won't see them unless you explicitly pull them |

| 13:53:56 | Torne | the default refspec for a fresh clone fetches refs/heads/* to refs/remotes/origin/* so anything outside heads won't appear in your tab completion as your local repo won't know about it |
| 13:54:58 | AlexandrosSchill | Nah, my bad. I should have noticed |

| 13:56:48 | Torne | it won't actually disappear in people's existing copies unless they git fetch −−prune |
| 13:56:53 | Torne | but it won't appear in new copies |

| 14:20:41 | amiconn | jhMikeS, n1s: Since coldfire has icache, having code in iram isn't that important. It can still be useful for code that is used a lot |
| 14:20:46 | *** | Saving seen data "./dancer.seen" |
| 14:21:45 | amiconn | The icache is somewhat nasty. Because it's direct mapped,relative location of functions in dram matters. This is probably what you're seeing |
| 14:22:58 | jhMikeS | It's only about 11 fps (4621/4611), just substituting regular lcd_bitmap functions for the greylib calls |
| 14:23:46 | jhMikeS | s/4611/4610/ |
| 14:41:59 | jhMikeS | If those bmp functions are moved to dram, then there's some iram to spare without much to worry about for speed. I just wonder, is it really critical in that sense on any other target to have them as icode? |
| 14:46:17 | amiconn | Substituting what, where? |
| 14:47:41 | jhMikeS | calling rb->lcd_bitmap instead of grey_ub_gray_bitmap since test_fps doesn't do the framebuffer functions by default |
| 14:48:19 | amiconn | Use test_gfx |
| 14:49:10 | jhMikeS | heh...forgot about that one |
| 14:49:11 | amiconn | Hmm, that one doesn't do native bitmaps though |
| 14:49:25 | jhMikeS | oh |
| 14:49:27 | amiconn | But it does text, i.e. mono bitmaps |
| 14:50:52 | amiconn | test_fps() is probably a bad example, because it uses large bitmaps, where most time is spent in lowlevel stuff like memcpy() |
| 14:54:23 | jhMikeS | what do you mean? I just see small loops calling grey_ub_gray_bitmap |
| 15:00 |

| 20:28:09 | pamaury | there can be several request with the same parameters |
| 20:28:15 | pamaury | to request several endpoints |
| 20:31:01 | wodz | hmm I am slowly starting to understand |
| 20:31:37 | pamaury | let's take an example: you device has 3 endpoint, each endpoint can handle any type and is bidirectional |
| 20:31:58 | wodz | mine has 16 endpoints |
| 20:32:02 | pamaury | is someone request a bulk ep IN, you will configure EP1IN as bulk |
| 20:32:19 | pamaury | then if someone request a int ep OUT, you will configure EP2OUT as int |
| 20:32:38 | wodz | ha here is the trick - rk27xx has predefined endpoints |
| 20:32:42 | pamaury | finally, if someone request a bulk ep OUT, you can configure EP1OUT as bulk because EP1 is bidirectional |
| 20:33:06 | pamaury | wait, I'll have a look a the rk27xx datasheet |
| 20:33:12 | wodz | I can't switch BULK1 into something else |
| 20:34:29 | pamaury | indeed, in your case you have unidirectional endpoints |
| 20:36:47 | pamaury | EP1=bulk out,EP2=bulk in,EP3=int in, EP4=bulk out,EP5=bulk in,EP6=int in, ... |
| 20:37:46 | pamaury | so you only need to keep a map of boolean saying for each endpoint if it used or not. when requested for a endpoint, you look for the first endpoint of that type which is free and select it |

| 20:41:50 | amiconn | nope |
| 20:41:59 | wodz | why? |
| 20:42:15 | amiconn | DMA with auto-align is broken, and without it it's slower than using the cpu |
| 20:42:39 | wodz | broken i which way? |
| 20:43:06 | wodz | I recall we set aa mode in pcm driver |
| 20:43:29 | amiconn | It transfers garbage if enabled |
| 20:44:06 | wodz | so why we use this in pcm transfers? |
| 20:44:19 | amiconn | Auto-align? |
| 20:44:22 | amiconn | Afaik we don't |
| 20:44:32 | wodz | hmm pcm transfers are 4byte aligned I guess |
| 20:44:51 | wodz | DCR0 = DMA_INT | DMA_EEXT | DMA_CS | DMA_AA | DMA_SINC | DMA_SSIZE(DMA_SIZE_LINE) | DMA_START; |
| 20:44:58 | wodz | so I guess we use AA |
| 20:45:07 | amiconn | There are further restrictions. (1) memcpy/memmove might be called in an isr, potentially interrupting another memcpy/memmove. We'd have to protect from this and resort to using the cpu if it happens -> more complexity |
| 20:45:32 | rudi_s | Hi. http://www.rockbox.org/wiki/MajorChanges still lists changes since 3.8 (SVN), maybe this could get updated. Thanks for the new release. |
| 20:45:41 | amiconn | (2) Iirc DMA can only copy forward -> it can't be used for memove if the kind of overlap demands backwards copying |
| 20:45:59 | amiconn | (3) There are memory blocks (namely the second iram bank) which aren't dma capable |
| 20:46:53 | amiconn | wodz: It may be that auto-align works in (dma capable) iram, but when I tried it with dram (for H300 lcd) it didn't work |
| 20:48:12 | wodz | the fact that pcm samples are 4bytes alligned may be the reason it just work |
| 20:49:06 | amiconn | It would only be useful if dma would actually be faster, because we'd have to busy-poll for completion |
| 20:49:50 | amiconn | Usually we'd set up an isr for signalling completion and then yield(), but we can't do those things in stuff as low-level as memcpy |
| 20:50:10 | amiconn | It might be called before the threading system is set up, or with interrupts disabled etc... |
| 20:51:13 | wodz | At least in my tests on mpios dma was faster than somehow optimized writes to lcd. But other problems with DMA are predominant here |
| 20:51:41 | wodz | anyway memcpy/memmove *are* the monsters :-) |

| 20:56:24 | wodz | interrupt ep is always in? |
| 20:56:44 | gevaerts | no |
| 20:57:01 | gevaerts | Most uses probably are though |
| 20:57:15 | wodz | hmm so looks like rk27xx has no out interrupt endpoint |
| 20:58:05 | gevaerts | In fact, I can't really think of anything more or less common that actually uses interrupt out |

| 21:02:41 | jhMikeS | Is there possibly an objection to IRAM splits between core and codec that are smaller grained than 0x1000? |
| 21:05:43 | amiconn | Not from me. Just keep in mind that you need to bum the codec and plugin api versions (including minimum version) when changing iram split |
| 21:06:19 | jhMikeS | oh, definitely. they won't link at the correct address. |
| 21:06:36 | jhMikeS | or currently be linked rather |
| 21:06:36 | amiconn | Actually this isn't necessary when moving the boundary down, but it definitely is when moving it up |
| 21:07:10 | jhMikeS | Well, I plan so far to move it up by 0x800 |
| 21:07:12 | amiconn | The codecs and plugins would load and run, but they would overwrite part of core iram |
| 21:07:25 | jhMikeS | which is bad? :) |
| 21:07:42 | amiconn | You might wait whether we can free some iram elsewhere |
| 21:07:49 | amiconn | *might want to |
| 21:08:37 | jhMikeS | Sure, np. It still works anyway for what it has to do right now. Though, from where would it come? |
| 21:08:55 | amiconn | icode, probably |
| 21:09:16 | amiconn | E.g. the monster I mentioned ~half an hour ago |
| 21:09:27 | jhMikeS | ah, the memcpy/move monster |
| 21:13:15 | jhMikeS | it'll sure get used alot now unless I implement a cut-down specialty version like I did for arm, but for arm it's simple |

| 21:39:31 | jhMikeS | Torne: whee...props then! :) |

| 21:40:23 | Torne | jhMikeS: but that's the only metadata you can break ;) |
| 21:41:19 | gevaerts | wodz: the important bit is that you get the interrupts :) I don't think it matters much whether you enable them from usb_drv_request_endpoint() or the controller init |

| 23:44:51 | sideral | Which target's Rockbox keymap is considered the most generic one (with the fewest deviations from the "Rockbox standard")? |
