Update #3706
|
|
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.
|
|
|
|
Add call to _Scheduler_Schedule() in missing path after
_Thread_Set_transient() in _Thread_Change_priority(). See also
sptests/spintrcritical19.
Add thread parameter to _Scheduler_Schedule(). This parameter is
currently unused but may be used in future SMP schedulers.
Do heir selection in _Scheduler_Schedule(). Use
_Scheduler_Update_heir() for this in the particular scheduler
implementation.
Add and use _Scheduler_Generic_block().

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.

pluggable scheduler interface. Its configuration made a table
of available schedulers and set a pointer to one of the.
This was heavy handed since you can only use one scheduler
in an application. This configuration mechanism resulted in a
scheduler pointer being passed around when you could put all
scheduler configuration in an initialized structure.
