* FS#12412 : Delete old buffer allocation code which has been replaced by ↵Boris Gjenero2011-11-29
| | | | | | core_alloc, and move buffer setup code to core_alloc.c git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31088 a1c6a512-1295-4272-9138-f99709370657

| | | | | | | The buffer_offset paramter of audio_init_recording() is removed as it was unused in both implementations. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30310 a1c6a512-1295-4272-9138-f99709370657
* GSoC/Buflib: Replace all direct accesses to audiobuf with buffer API functions.Thomas Martitz2011-08-14
| | | | | | | | | | | | | | | | | | | | | | | Namely, introduce buffer_get_buffer() and buffer_release_buffer(). buffer_get_buffer() aquires all available and grabs a lock, attempting to call buffer_alloc() or buffer_get_buffer() while this lock is locked will cause a panicf() (doesn't actually happen, but is for debugging purpose). buffer_release_buffer() unlocks that lock and can additionally increment the audiobuf buffer to make an allocation. Pass 0 to only unlock if buffer was used temporarily only. buffer_available() is a replacement function to query audiobuflen, i.e. what's left in the buffer. Buffer init is moved up in the init chain and handles ipodvideo64mb internally. Further changes happened to mp3data.c and talk.c as to not call the above API functions, but get the buffer from callers. The caller is the audio system which has the buffer lock while mp3data.c and talk mess with the buffer. mpeg.c now implements some buffer related functions of playback.h, especially audio_get_buffer(), allowing to reduce #ifdef hell a tiny bit. audiobuf and audiobufend are local to buffer.c now. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30308 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.
