2011-08-30Dircache: Allow dircache to be enabled without reboot.Thomas Martitz
Also add two dircache function, one of which does what dircache_disable() did previously as this now also frees the dircache buffer. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30393 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
2011-06-21Try to handle dircache rebuild event properly. Playlist should nowMiika Pekkarinen
cache new pointers to dircache items when dircache goes offline and comes back onlineagain (during tagcache commit). This should prevent wrong filenames to appear in playlist. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30047 a1c6a512-1295-4272-9138-f99709370657
2011-06-20Dircache: Don't expose struct dircache_entry and pointers into the cache, ↵Thomas Martitz
use IDs instead. Only integer IDs are exposed from dircache with this. This way the cache is isolated from other modules. This is needed for my buflib gsoc project. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30038 a1c6a512-1295-4272-9138-f99709370657
2011-06-20Dircache: Move struct maindata declaration to dircache.c and actually check ↵Thomas Martitz
for DIRCACHE_MAGIC when loading from disk. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30037 a1c6a512-1295-4272-9138-f99709370657
2011-06-20Dircache: Change internal cache layout.Thomas Martitz
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
2011-06-20Dircache: Return the size of the result string in dircache_copy_path() so ↵Thomas Martitz
that callers don't need to call strlen on it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30034 a1c6a512-1295-4272-9138-f99709370657
2011-06-20Dircache: Remove dircache_entry::name_len.Thomas Martitz
It's reduntant, and enlarges the dircache unnecessarily. Saves 4 byte per file in the whole filesystem. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30032 a1c6a512-1295-4272-9138-f99709370657

2010-09-01Ged rid of uisimulator/common/io.c for android builds.Thomas Martitz
Use host's functions for file i/o directly (open(), close() ,etc.), not the sim_* variants. Some dir functions need to be wrapped still because we need to cache the parents dir's path (host's dirent doesn't let us know). For the same reason (incompatibility) with host's dirent) detach some members from Rockbox' dirent struct and put it into an extra one, the values can be retrieved via the new dir_get_info(). Get rid of the sim_ prefix for sleep as well and change the signature to unix sleep(). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27968 a1c6a512-1295-4272-9138-f99709370657
2010-08-01Rockbox as an application: add get_user_file_path().Thomas Martitz
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
2010-06-21Rockbox as an application: Replace many occurences of #ifdef SIMULATOR with ↵Thomas Martitz
#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
2010-03-03FS#10756 - Free unused init codeThomas Martitz
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. More targets could be added, as well as more functions. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@25013 a1c6a512-1295-4272-9138-f99709370657
