Daniel Stenberg	2acc0ac542	Updated our source code header to explicitly mention that we are GPL v2 or ... later. We still need to hunt down snippets used that are not. 1324 modified files... http://www.rockbox.org/mail/archive/rockbox-dev-archive-2008-06/0060.shtml git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17847 a1c6a512-1295-4272-9138-f99709370657	2008-06-28 18:10:04 +00:00
Michael Sevakis	af395f4db6	Do core interrupt masking in a less general fashion and save some instructions to decrease size and speed things up a little bit. Small fix to a few places where interrupts would get enabled again where they shouldn't have been (context switching calls when disabled). ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16811 a1c6a512-1295-4272-9138-f99709370657	2008-03-26 01:50:41 +00:00
Michael Sevakis	27cf677339	Add a complete priority inheritance implementation to the scheduler (all 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	2008-03-25 02:34:12 +00:00
Michael Sevakis	c935ed5112	Argh. Forgot to 'svn add' as usual. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15322 a1c6a512-1295-4272-9138-f99709370657	2007-10-26 23:16:41 +00:00
