* Ged rid of uisimulator/common/io.c for android builds.Thomas Martitz2010-09-01
| | | | | | | | | | | 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

* Add a complete priority inheritance implementation to the scheduler (all ↵Michael Sevakis2008-03-25
| | | | | | mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16791 a1c6a512-1295-4272-9138-f99709370657
