Updates #3053.
|
|
Use common phrases for the file brief descriptions.
Update #3706.
|
|
Use the following variant which was already used by most source files:
#ifdef HAVE_CONFIG_H
#include "config.h"
#endif
|

Update #3706

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().
Update #2412.
Update #2556.

Provide the scheduler node to initialize or destroy to the corresponding
operations. This makes it possible to have more than one scheduler node
per thread.
|
|
The thread priority is manifest in two independent areas. One area is
the user visible thread priority along with a potential thread queue.
The other is the scheduler. Currently, a thread priority update via
_Thread_Change_priority() first updates the user visble thread priority
and the thread queue, then the scheduler is notified if necessary. The
priority is passed to the scheduler via a local variable. A generation
counter ensures that the scheduler discards out-of-date priorities.
This use of a local variable ties the update in these two areas close
together. For later enhancements and the OMIP locking protocol
implementation we need more flexibility. Add a thread priority
information block to Scheduler_Node and synchronize priority value
updates via a sequence lock on SMP configurations.
Update #2556.

The following scheduler operations return a thread in need for help
- unblock,
- change priority, and
- yield.
A thread in need for help is a thread that encounters a scheduler state
change from scheduled to ready or a thread that cannot be scheduled in
an unblock operation. Such a thread can ask threads which depend on
resources owned by this thread for help.
Add a new ask for help scheduler operation. This operation is used by
_Scheduler_Ask_for_help() to help threads in need for help returned by
the operations mentioned above. This operation is also used by
_Scheduler_Thread_change_resource_root() in case the root of a resource
sub-tree changes. A use case is the ownership change of a resource.
In case it is not possible to schedule a thread in need for help, then
the corresponding scheduler node will be placed into the set of ready
scheduler nodes of the scheduler instance. Once a state change from
ready to scheduled happens for this scheduler node it may be used to
schedule the thread in need for help.
|
|
Replace _Scheduler_Allocate() with _Scheduler_Node_initialize(). Remove
the return status and thus the node initialization must be always
successful.
Rename _Scheduler_Free() to _Scheduler_Node_destroy().
|
|
The thread control block contains fields that point to application
configuration dependent memory areas, like the scheduler information,
the API control blocks, the user extension context table, the RTEMS
notepads and the Newlib re-entrancy support. Account for these areas in
the configuration and avoid extra workspace allocations for these areas.
This helps also to avoid heap fragementation and reduces the per thread
memory due to a reduced heap allocation overhead.
|
|
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_simple_Allocate() in _Scheduler_default_Allocate().
Rename _Scheduler_simple_Free() in _Scheduler_default_Free().
|
|
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.
