* Move strncpy() from core to the pluginlib * Introduce strlcpy() and use that instead in most places (use memcpy in a few) in core and some plugins * Drop strncpy() from the codec api as no codec used it * Bump codec and plugin api versions git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21863 a1c6a512-1295-4272-9138-f99709370657

2008-12-10Use cookies for thread identification instead of pointers directly which ↵Michael Sevakis
gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats.

2008-10-23Remove the event object in the kernel since it's rather extraneous at the ↵Michael Sevakis
moment. This makes the codecs and the plugins incompatible, so update fully. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18867 a1c6a512-1295-4272-9138-f99709370657
2008-10-19Codec memory reorganizationNils Wallménius
Based on a patch by Tomasz Malesinski * Merge Codec buffer and Malloc buffer into one large buffer. * The new merged buffer is now 1MB on targets with lots of memory. * Renamed codec_get_memory to codec_get_buffer and made it behave more. like plugin_get_buffer. * Bumped Codec api and min api versions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18834 a1c6a512-1295-4272-9138-f99709370657

2008-03-25Add a complete priority inheritance implementation to the scheduler (all ↵Michael Sevakis
mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16791 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

2007-07-03Initial, work-in-progress, version of a WMA codec using Michael Giacomelli's ↵Dave Chapman
fixed-point and malloc-less WMA decoder (based on the ffmpeg WMA decoder from early 2006, and also building on the work started by Paul Jones). The codec itself and the ASF parsing code were written by me, inspired by the ASF parser in libasf. Current performance is around 400% realtime on gigabeat, 100% realtime on PP and 20% realtime on Coldfire. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13769 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

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
2007-02-24SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of ↵Michael Sevakis
some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12472 a1c6a512-1295-4272-9138-f99709370657
2007-02-10SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback ↵Michael Sevakis
and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12259 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

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
