* GSoC/Buflib: Enable compaction in buflib.Thomas Martitz2011-08-30
| | | | | | | | | | | | | | | | | | | This enables the ability to allocate (and free) memory dynamically without fragmentation, through compaction. This means allocations can move and fragmentation be reduced. Most changes are preparing Rockbox for this, which many times means adding a move callback which can temporarily disable movement when the corresponding code is in a critical section. For now, the audio buffer allocation has a central role, because it's the one having allocated most. This buffer is able to shrink itself, for which it needs to stop playback for a very short moment. For this, audio_buffer_available() returns the size of the audio buffer which can possibly be used by other allocations because the audio buffer can shrink. lastfm scrobbling and timestretch can now be toggled at runtime without requiring a reboot. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30381 a1c6a512-1295-4272-9138-f99709370657
* GSoC/Buflib: Add buflib memory alocator to the core.Thomas Martitz2011-08-30
| | | | | | | | | | | | | | | | | The buflib memory allocator is handle based and can free and compact, move or resize memory on demand. This allows to effeciently allocate memory dynamically without an MMU, by avoiding fragmentation through memory compaction. This patch adds the buflib library to the core, along with convinience wrappers to omit the context parameter. Compaction is not yet enabled, but will be in a later patch. Therefore, this acts as a replacement for buffer_alloc/buffer_get_buffer() with the benifit of a debug menu. See buflib.h for some API documentation. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30380 a1c6a512-1295-4272-9138-f99709370657
