kernel: Break out kernel primitives into separate files and move to separate dir.

2014-03-03T17:11:57+00:00

No code changed, just shuffling stuff around. This should make it easier to
build only select parts kernel and use different implementations.

buflib: Add crc field protecting buflib cookie integrity

2014-01-16T09:17:39+00:00

This should catch the case of buffer misuse which results
in corrupted cookie of next allocation. The check is performed
on move_block() so it may be a bit late.

There is buflib_check_valid() provided which checks the
integrity of all cookies for given context.
On DEBUG build with --sdl-thread this check is carried out
for core_ctx on every context switch to catch problems earlier.

Use commit_dcache() instead of commit_discard_idcache() where possible

2012-02-05T03:27:42+00:00

- PCM playback DMA doesn't need the discard. Only recording DMA would
  need it.
- When creating threads for another core, the core creating the thread only
  needs to commit. The discard on the other core is handled elsewhere.

Fix FS#12559: sigaltstack threads fortify failure

2012-01-27T01:33:28+00:00

Ubuntu defines _FORTIFY_SOURCE=2, which causes glibc longjmp() to check sp
when gcc optimization is enabled. The check does not allow longjmp() to be
used for switching threads and results in a "longjmp causes uninitialized
stack frame" error. This disables the check.

Create fimrware/asm directory for assembly optimized stuff.

2012-01-22T17:46:44+00:00

This dir is suitable for stuff that doesn't fit the target tree, e.g. because
it also builds on hosted or otherwise. It also has a generic subfolder for
fallback C implementations so that not all archs need to provide asm files.

SOURCES should only contain "foo.c" where foo.c includes the specific
/foo.c files from the subdirs using the preprocessor. This way automatic
selection of asm versions or generic C verion is possible.

For the start, the thread support files are moved, since ASM threads can
be used on hosted platforms as well. Since core_sleep() remains platform
specific it's moved to the corresponding system.h headers.

Commit to certain names for cache coherency APIs and discard the aliases.

Wouldn't surprise me a bit to get some non-green.

Change the thread api a bit.

2011-03-05T17:48:06+00:00

* Remove THREAD_ID_CURRENT macro in favor of a thread_self() function, this allows thread functions to be simpler.
* thread_self_entry() shortcut for kernel.c.
