2007-11-30Move encoder CPU boost control to the core. Allow CPU to sleep a bit when ↵Michael Sevakis
PCM buffer is empty and save some power. Codec API becomes incompatible so full updates! :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15854 a1c6a512-1295-4272-9138-f99709370657

codec swapping and build speex voice decoding directly into the core binary. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15668 a1c6a512-1295-4272-9138-f99709370657

2007-11-02Make bufread and bufgetdata blocking. They now return when enough data is ↵Nicolas Pennequin
available or when EOF is reached. This improves the API and removes the need for several duplicate waiting loops. Also fix a few logfqueue messages. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15412 a1c6a512-1295-4272-9138-f99709370657

2007-11-02Improve upon my hackity hack from before by separating audio into two types: ↵Brandon Low
that which may be large and can be streamed and that which is small and cannot be streamed. While modifying types, allow codecs to split across the buffer wrap and dig out/move around the code that reads a codec off of the buffer to facilitate that simple sounding change. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15408 a1c6a512-1295-4272-9138-f99709370657
2007-10-24logf changes:Nicolas Pennequin
* Disable logf by default and allow per-file enabling with "#define LOGF_ENABLE". To enable globally add that define in the config.h file. * Transform logf calls into DEBUGF calls when ROCKBOX_HAS_LOGF isn't defined, so that they get printed to the console in the sim. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15291 a1c6a512-1295-4272-9138-f99709370657
2007-09-28Commit a subset of the dual core changes that have to do with cache ↵Michael Sevakis
handling, stacks, firmware startup and thread startup. Tested on e200, H10-20GB, iPod Color and 5.5G. Thread function return implemented for all targets. Some changes to plugins to follow shortly. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14879 a1c6a512-1295-4272-9138-f99709370657
2007-05-07Clean up the codec API - remove all unused (and in many cases inappropriate) ↵Dave Chapman
functions, move functions used only by encoders into the HAVE_RECORDING part of the API and document the reasons for the more unexpected functions being present. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13343 a1c6a512-1295-4272-9138-f99709370657
2007-04-21General housekeeping: Make plugin buffer functions take size_t * instead of ↵Michael Sevakis
int * to match the parameter type of the buffer functions called in the core. Get rid of unsafe int * <==> size_t * casting. Use ssize_t where int was used and size_t where unsigned int was used in the buffer calls to not alter signedness in the plugins. No API version change since it should only be an issue for 64-bit sim builds. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13233 a1c6a512-1295-4272-9138-f99709370657
2007-03-16Get rid of the 'center' parameter for splashes. There were only 2 of almost ↵Jens Arnold
500 splashes which were not centered. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12807 a1c6a512-1295-4272-9138-f99709370657
2007-03-04Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - ↵Daniel Ankers
iPod G3 will be coming soon.) This allows threads to be run on either core provided that all communications between the cores is done using uncached memory. There should be no significant change in battery life from doing this. Documentation (on the RockboxKernel wiki page) will follow shortly. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12601 a1c6a512-1295-4272-9138-f99709370657
2007-03-04SWCODEC Recording Codecs: Fix problems with hanging recording screen ↵Michael Sevakis
(chiefly on x5) when no voice file present and source is not FMRadio. Caused by extra audio stops causing encoder to unload prematurely. Fix is to have separate stop flags for each codec type to prevent collisions. Also now safe to plug into USB when recording and encoder will stay loaded and not be stopped by the call to audio_stop_playback. Additional discovery: playback will not be able to restart after a USB plug during recording. Probably an old bug. I recommend in the future that recording have higher priority on system resources than playback and playback be denied access explicitly if recording requires them. Codec API becomes incompatible so do full updates. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12579 a1c6a512-1295-4272-9138-f99709370657
2007-02-07Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis
clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12218 a1c6a512-1295-4272-9138-f99709370657

2006-11-26FS#6357, patch 1: let iramcopy and bss share the same space in codecs andTomasz Malesinski
plugins. Currently, in case of plugins using IRAM bss is cleared twice, once in the loader, once in PLUGIN_IRAM_INIT. For codecs, bss is cleared only during codec initialization. Also, removed double variables in codecs storing a pointer to codec_api. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11606 a1c6a512-1295-4272-9138-f99709370657
2006-11-06Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis
SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11452 a1c6a512-1295-4272-9138-f99709370657

2006-09-16New scheduler, with priorities for swcodec platforms. Frequent taskMiika Pekkarinen
