The function to change a thread priority was too complex. Simplify it
with a new scheduler operation. This increases the average case
performance due to the simplified logic. The interrupt disabled
critical section is a bit prolonged since now the extract, update and
enqueue steps are executed atomically. This should however not impact
the worst-case interrupt latency since at least for the Deterministic
Priority Scheduler this sequence can be carried out with a wee bit of
instructions and no loops.
Add _Scheduler_Change_priority() to replace the sequence of
- _Thread_Set_transient(),
- _Scheduler_Extract(),
- _Scheduler_Enqueue(), and
- _Scheduler_Enqueue_first().
Delete STATES_TRANSIENT, _States_Is_transient() and
_Thread_Set_transient() since this state is now superfluous.
With this change it is possible to get rid of the
SCHEDULER_SMP_NODE_IN_THE_AIR state. This considerably simplifies the
implementation of the new SMP locking protocols.
|
|
Rename scheduler per-thread information into scheduler nodes using
Scheduler_Node as the base type. Use inheritance for specialized
schedulers.
Move the scheduler specific states from the thread control block into
the scheduler node structure.
Validate the SMP scheduler node state transitions in case RTEMS_DEBUG is
defined.
|
|
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.
|
|
Delete global variables _Priority_Major_bit_map and _Priority_Bit_map.
This makes it possible to use multiple priority scheduler instances for
example with clustered/partitioned scheduling on SMP.
|
|
|
|
Move implementation specific parts of schedulerpriority.h and
schedulerpriority.inl into new header file schedulerpriorityimpl.h. The
schedulerpriority.h contains now only the application visible API.
Add missing includes. Remove superfluous includes.
Move declaration of _Priority_Bit_map to prioritybitmap.inl since this
variable is used only here.
Remove second declaration of _Priority_Major_bit_map.

This patch is a task from GCI 2012 which improves the Doxygen
comments in the RTEMS source.

Script does what is expected and tries to do it as
smartly as possible.
+ remove occurrences of two blank comment lines
next to each other after Id string line removed.
+ remove entire comment blocks which only exited to
contain CVS Ids
+ If the processing left a blank line at the top of
a file, it was removed.

Significant clean up on Scheduler Plugin Interface. Names were
shortened. Missing operations added. Many scheduler files had
unneeded includes removed. Made pointer to scheduler information in
Thread_Control and Scheduler_Control a void * pointer because the
thread and scheduler wrapper should be unaware of scheduler types AND
this is broken for user provided schedulers.
