2011-11-17Buflib: Make shrinking and buflib_available() smarter.Thomas Martitz
* shrinking now considers freespace just before the alloc-to-be-shrinked, that means less (or sometimes none at all) is taken from the audio buffer. * core_available() now searches for the best free space, instead of simply the end, i.e. it will not return 0 if the audio buffer is allocated and there's free space before it. It also runs a compaction to ensure maximum contiguous memory. audio_buffer_available() is also enhanced. It now considers the 256K reserve buffer, and returns free buflib space instead if the audio buffer is short. This all fixes the root problem of FS#12344 (Sansa Clip+: PANIC occurred when dircache is enabled), that alloced from the audio buffer, even if it was very short and buflib had many more available as free space before it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31006 a1c6a512-1295-4272-9138-f99709370657

2011-11-06hwcodec: fix shrink_callback resuming playback wrongly, and add checksThomas Martitz
if the voice is bigger than the audiobuffer. NOTE: This is the case on the sim so voice doesn't appear to work currently on hwcodec. Someone needs to verify on a real target. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30910 a1c6a512-1295-4272-9138-f99709370657
2011-10-09Another fix for audio_get_buffer() on hwcodec by Thomas Martitz.Jens Arnold
Some functions must only be called when audio is already initialized, due to talk <-> audio interdependency, same as on swcodec. This makes hwcodec boot and play music again. Voice menus also working again, talk clips not yet. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30738 a1c6a512-1295-4272-9138-f99709370657

2011-08-30GSoC/Buflib: Enable compaction in buflib.Thomas Martitz
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
2011-08-30GSoC/Buflib: Add buflib memory alocator to the core.Thomas Martitz
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

2011-08-14GSoC/Buflib: Replace all direct accesses to audiobuf with buffer API functions.Thomas Martitz
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

swcodec: search for a .cue during buffering (with the possibility of adding embedded cuesheets later) hwcodec: search for a .cue when the id3 info for the current track is requested for the first time (disk should be spining so non issue) major beenfit from this is simplofy cuesheet handling code a bit... if mp3entry.cuesheet != NULL then there is a valid cuesheet.. no need to worry about if its enabled and preloaded. There is the possibility of putting the next/prev subtrack handling inside the playback code (as well as the id3 updating stuff (see FS#9789 for more info), but thats probably not a good idea. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21978 a1c6a512-1295-4272-9138-f99709370657

2009-04-06FS9795 - some playback cleanup. Jonathan Gordon
* Use events to notify things when the track has changed instead of the nasty has_track_changed() * Event for when the mp3entry for the next track is avilable (which allows alot more tags to be static which means less redrawing in the WPS) * virtually guarentee that the mp3entry sturct returned by audio_current/next_track() is going to be valid for the duration of the current track. The only time it wont be now is during the time between the codec finishing the previous track and the next track actually starting (~2s), but this is not an issue as long as it is called again when the TRACK_CHANGED event happens (or just use the pointer that gives) It is still possible to confuse the WPS with the next tracks id3 info being displayed but this should fix itself up faster than it used to (and be harder to do) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20633 a1c6a512-1295-4272-9138-f99709370657
