The exception is target code for particular CPUs where proper allocation is fixed. playlist.c was a little odd too-- use one mutex for the current playlist and a separate one for created playlists (still pondering the necessity of more than one). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@29305 a1c6a512-1295-4272-9138-f99709370657

* Implement chasing bitswap for reading. Speeds up reading single 512-byte ↵Jens Arnold2008-09-14
| | | | | | blocks by 15..20%. * Restructure the write buffer handling a bit, making it more readable and a bit smaller. Also fixes an old corner case bug: writing data from address 0x0 (archos boot ROM dump) would have written wrong data. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18516 a1c6a512-1295-4272-9138-f99709370657
* Simplify & fix the MMC driver. After more than 3 years I found that the MMC ↵Jens Arnold2008-09-14
| | | | | | specs were a bit misleading, and the 'large' MMC which state a block size of 1024 or 2048 bytes and no partial read and/or partial write capability are happily accepting a block size of 512 bytes. So go KISS and remove all the variable/partial block handling code. This fixes the driver for the Transcend 4GB MMCplus, which doesn't cope when we actually set the 2048 byte block size it states. It also makes write operations involving small blocks faster and more reliable. * Note: The 4GB Transcend still doesn't work when plugged at boot, but works when hotplugged. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18515 a1c6a512-1295-4272-9138-f99709370657

* Finally full multicore support for PortalPlayer 502x targets with an eye ↵Michael Sevakis2007-10-16
| | | | | | towards the possibility of other types. All SVN targets the low-lag code to speed up blocking operations. Most files are modified here simple due to a name change to actually support a real event object and a param change to create_thread. Add some use of new features but just sit on things for a bit and leave full integration for later. Work will continue on to address size on sensitive targets and simplify things if possible. Any PP target having problems with SWP can easily be changed to sw corelocks with one #define change in config.h though only PP5020 has shown an issue and seems to work without any difficulties. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15134 a1c6a512-1295-4272-9138-f99709370657
