Add priority nodes which contribute to the overall thread priority.
The actual priority of a thread is now an aggregation of priority nodes.
The thread priority aggregation for the home scheduler instance of a
thread consists of at least one priority node, which is normally the
real priority of the thread. The locking protocols (e.g. priority
ceiling and priority inheritance), rate-monotonic period objects and the
POSIX sporadic server add, change and remove priority nodes.
A thread changes its priority now immediately, e.g. priority changes are
not deferred until the thread releases its last resource.
Replace the _Thread_Change_priority() function with
* _Thread_Priority_perform_actions(),
* _Thread_Priority_add(),
* _Thread_Priority_remove(),
* _Thread_Priority_change(), and
* _Thread_Priority_update().

Split up the potential thread priority change in the scheduler
release/cancel job operation. Protect the rate monotonic period state
with a dedicated SMP lock. This avoids a race condition during
_Rate_monotonic_Timeout() while _Rate_monotonic_Cancel() is called on
another processor.

Do not use a deadline value of zero to indicate a job cancellation. Use
a dedicated scheduler operation for this.
|

Pass the deadline in watchdog ticks to the scheduler.

Do not allocate the scheduler control structures from the workspace.
This is a preparation step for configuration of clustered/partitioned
schedulers on SMP.
|
| |
|
|
|
| |
Scheduler operations must be free of a global scheduler context to
enable partitioned/clustered scheduling.

Rename _Scheduler_priority_Release_job() into
_Scheduler_default_Release_job().
