Add CPU mode asserts to kernel on blocking functions.

This scourge finds it's way back in far too often.
Right now, only defined for ARM.

Have fun!

Remove I/O priority. It is harmful when used with the new file code.

2014-08-30T18:01:21+00:00

HAVE_IO_PRIORITY was defined for native targets with dircache.

It is already effectively disabled for the most part since dircache no
longer lowers its thread's I/O priority. It existed primarily for the
aforementioned configuration.

panicf doesn't return so why not tell GCC and $AVE :

Make sure load_context is the last thing in switch_thread.

This should fix the android crash issue (fingers crossed).

Fix warnings from 6ed0087

2014-08-16T10:00:36+00:00

Forgot to (void) an unused parameter when priorityless.

usb-drv-rl27xx.c was using a compound init to initialize a semaphore
but the structure changed so that it is no longer correct. Use
designated initializers to avoid having to complete all fields.

Forgot to break compatibility on all plugins and codecs since the
kernel objects are now different. Take care of that too and do the
sort thing.

Base scheduler queues off linked lists and do cleanup/consolidation

2014-08-16T09:15:37+00:00

Abstracts threading from itself a bit, changes the way its queues are
handled and does type hiding for that as well.

Do alot here due to already required major brain surgery.

Threads may now be on a run queue and a wait queue simultaneously so
that the expired timer only has to wake the thread but not remove it
from the wait queue which simplifies the implicit wake handling.

List formats change for wait queues-- doubly-linked, not circular.
Timeout queue is now singly-linked. The run queue is still circular
as before.

Adds a better thread slot allocator that may keep the slot marked as
used regardless of the thread state. Assists in dumping special tasks
that switch_thread was tasked to perform (blocking tasks).

Deletes alot of code yet surprisingly, gets larger than expected.
Well, I'm not not minding that for the time being-- omlettes and break
a few eggs and all that.

Fix some more straggling stuff

2014-08-08T07:23:29+00:00

* HWCODEC bootloaders

* Remove references to thread structures outside the kernel. They are
private and should not be used elsewhere. The mrobe-100 is an offender
that gets squashed.

* The ata.c hack stuff for large sector disks on iPod Video gets squashed
for the same reason. I will no longer maintain it, period; please find
the real reason for its difficulties.

Do some kernel cleanup

2014-08-08T05:59:59+00:00

* Seal away private thread and kernel definitions and declarations
into the internal headers in order to better hide internal structure.

* Add a thread-common.c file that keeps shared functions together.
List functions aren't messed with since that's about to be changed to
different ones.

* It is necessary to modify some ARM/PP stuff since GCC was complaining
about constant pool distance and I would rather not force dump it. Just
bl the cache calls in the startup and exit code and let it use veneers
if it must.

* Clean up redundant #includes in relevant areas and reorganize them.

* Expunge useless and dangerous stuff like remove_thread().

Fix some stuff for no priority and

2014-08-06T06:27:49+00:00

thread_queue_wake() doesn't need the 2nd parameter. The original purpose
for it never came to be.

Non priority version mrsw_writer_wakeup_readers was left improperly
finished. Get that back into line.
