* Fix FS#12325 - screen corruption on early usb.Thomas Martitz2011-10-28
| | | | | | | | | | When booting with USB inserted, the dircache build can get interrupted by the usb connection, in which case the dircache buffer is freed. Due to a bug the re-creation of dircache used the old freed buffer and overwrite new allocs (causing screen corruption). Set allocated_size to 0 to make it not take the code path that assumes an existing buffer, and bring that and freeing together in the code. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30845 a1c6a512-1295-4272-9138-f99709370657

* 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
* Dircache: Fix memory leak (and recently panic).Thomas Martitz2011-08-16
| | | | | | | | | | | | | If the dircache was interrupted during generation (e.g. through USB insertion), then the allocated buffer was leaked and a new one was allocated for the second cache generation. This causes a panic since r30308 since playback holds the control over the audiobuffer at that time. The fix is to simply check allocated_size instead of dircache_size which is reset to 0 upon cancellation. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30321 a1c6a512-1295-4272-9138-f99709370657
* Dircache: Fix bug introduced in r30308.Thomas Martitz2011-08-15
| | | | | | | dircache_root wasn't initialized at all and the giving allocated_size passed to buffer_release_buffer() didn't account for alignment padding. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30318 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
* Dircache: Fix 2 nasty bugs introduced with the reworks starting with r30032.Thomas Martitz2011-07-30
| | | | | | | | | The first is an off-by-one that leads to miscalculation of the dircache size. The format string size was used but dircache size was incremented by the snprintf() result which is smaller. The other forgot to update the location of the "." and ".." strings upon compaction, so that new folders got assigned orphaned pointers for those directory entires. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30224 a1c6a512-1295-4272-9138-f99709370657

* Dircache: Change internal cache layout.Thomas Martitz2011-06-20
| | | | | | | | | The dircache_entry structs are now allocated subsequently from the front, allowing to treat them as an array. The d_names are allocated from the back (in reverse order, growing downwards). This allows the cache to be moved around (needed for my buflib gsoc project). It is utilized when loading the cache from disk (on the h100), now the pointer to the cache begin doesn't need to be the same across reboots anymore. This should save a bit memory usage, since there's no need for aligning padding bytes after d_names anymore. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30036 a1c6a512-1295-4272-9138-f99709370657

* Rockbox as an application: add get_user_file_path().Thomas Martitz2010-08-01
| | | | | | | | | | | For RaaA it evaluates user paths at runtime. For everything but codecs/plugins it will give the path under $HOME/.config/rockbox.org if write access is needed or if the file/folder in question exists there (otherwise it gives /usr/local/share/rockbox). This allows for installing themes under $HOME as well as having config.cfg and other important files there while installing the application (and default themes) under /usr/local. On the DAPs it's a no-op, returing /.rockbox directly. Not converted to use get_user_file_path() are plugins themselves, because RaaA doesn't build plugins yet. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27656 a1c6a512-1295-4272-9138-f99709370657
