* kernel: Break out kernel primitives into separate files and move to separate ↵Thomas Martitz2014-03-03
| | | | | | | | | dir. No code changed, just shuffling stuff around. This should make it easier to build only select parts kernel and use different implementations. Change-Id: Ie1f00f93008833ce38419d760afd70062c5e22b5
* Refactor audio thread to run both recording and playback.Michael Sevakis2013-05-31
| | | | | | | | | | | | | | | | Eliminates the pcmrec thread and keeps playback and recording engine operation mutually-exclusive. audio_thread.c contains the audio thread which branches to the correct engine depending upon the request. It also handles the main audio initialization. Moves pcm_init into main.c just before dsp_init because I don't want that one in audio_init in the new file. (Also makes revision df6e1bc pointless ;) Change-Id: Ifc1db24404e6d8dd9ac42d9f4dfbc207aa9a26e1

* Create fimrware/asm directory for assembly optimized stuff.Thomas Martitz2012-01-22
| | | | | | | | | | | | | | | | This dir is suitable for stuff that doesn't fit the target tree, e.g. because it also builds on hosted or otherwise. It also has a generic subfolder for fallback C implementations so that not all archs need to provide asm files. SOURCES should only contain "foo.c" where foo.c includes the specific <arch>/foo.c files from the subdirs using the preprocessor. This way automatic selection of asm versions or generic C verion is possible. For the start, the thread support files are moved, since ASM threads can be used on hosted platforms as well. Since core_sleep() remains platform specific it's moved to the corresponding system.h headers. Change-Id: Iebff272f3407a6eaafeb7656ceb0ae9eca3f7cb9

* Implement cooperative threads on hosted platforms using C code.Thomas Martitz2011-02-18
| | | | | | | | This replaces SDL threads with real cooperative threads, which are less cpu intensive and allow priority scheduling. The backend for context switching is dependant on the host (sigaltstack/longjmp on Unix, Fibers on Windows). configure has options to force or disallow SDL threads. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29327 a1c6a512-1295-4272-9138-f99709370657

Change queue clearing to simply catch read up to write rather than reset both to 0 to ensure sane results for queue_count and queue_empty with concurrency.

* Rockbox as an application: Commit current Android port progress.Thomas Martitz2010-08-02
| | | | | | | | | | | | | | | | General state is: Rockbox is usable (plays music, saves configuration, touchscreen works too). Problems: - Playing music in the background (i.e. when switching to another app) doesn't work reliably, but I'm working on that now. - no cabbiev2 (only some preliminary files for it), no other default theme. - screen flickers sometimes if the updates are too frequent - no multi screen apk/package - strange behavior when a phone call comes in The java files (and the eclipse project) resides in android/, which is also supposed to be the build folder. I've put a small README in there for instructions. There are some steps needed after the make part, which are described there, and which eclipse mostly handles. But there ought to be some script/makefile rules which do that instead in the future. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27668 a1c6a512-1295-4272-9138-f99709370657
* Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with ↵Thomas Martitz2010-06-21
| | | | | | | | | | | #if (CONFIG_PLATFORM & PLATFORM_HOSTED) (or equivalently). The simulator defines PLATFORM_HOSTED, as RaaA will do (RaaA will not define SIMULATOR). The new define is to (de-)select code to compile on hosted platforms generally. Should be no functional change to targets or the simulator. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27019 a1c6a512-1295-4272-9138-f99709370657

* FS#10756 - Free unused init codeThomas Martitz2010-03-03
| | | | | | | Introduce a new .init section for initialisation code, so that it can be copied to an area which is later overwritten before calling. The stack/bss can then overwrite that code, effectively freeing the code size that the initialisation routines need. Gives a few kB ram usage back. Only implemented for PP and as3525 so far.

* Add a complete priority inheritance implementation to the scheduler (all ↵Michael Sevakis2008-03-25
| | | | | | 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

* Finally commit Metadata on Buffer!Nicolas Pennequin2007-10-25
| | | | | | | | | buffering.c and buffering.h implement the new buffering API. playback.c is translated to that API. For more information about the whole concept, see http://www.rockbox.org/wiki/MetadataOnBuffer. There should be no major visible changes, but most existing bugs remain (though fixing them should be easier now that playback.c is a bit less complex) and there probably will be new ones. Please report any problem!

Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible.
