For semaphore object pointer and object validation see
POSIX_SEMAPHORE_VALIDATE_OBJECT().
Destruction or close of a busy semaphore returns an error status. The
object is not flushed.

The fatal is internal indicator is redundant since the fatal source and
error code uniquely identify a fatal error. Keep the fatal user
extension is internal parameter for backward compatibility and set it to
false always.

Resurrect RTEMS_LINKER_SET_BEGIN() and RTEMS_LINKER_SET_END().
Add new macros RTEMS_LINKER_SET_ITEM_COUNT(),
RTEMS_LINKER_SET_IS_EMPTY(), and
RTEMS_LINKER_SET_FOREACH().
Remove confusing RTEMS_LINKER_SET_ASSIGN_BEGIN() and
RTEMS_LINKER_SET_ASSIGN_END().
Fix RTEMS_LINKER_SET_SIZE() to return the size in characters as
specified by the documentation.

Replace the expected thread dispatch disable level with a thread queue
enqueue callout. This enables the use of _Thread_Dispatch_direct() in
the thread queue enqueue procedure. This avoids impossible exection
paths, e.g. Per_CPU_Control::dispatch_necessary is always true.

On SMP configurations, it is a fatal error to call blocking operating
system with interrupts disabled, since this prevents delivery of
inter-processor interrupts. This could lead to executing threads which
are not allowed to execute resulting in undefined behaviour.
The ARM Cortex-M port has a similar problem, since the interrupt state
is not a part of the thread context.
Update #2811.

This function is useful for operations which synchronously block, e.g.
self restart, self deletion, yield, sleep. It helps to detect if these
operations are called in the wrong context. Since the thread dispatch
necessary indicator is not used, this is more robust in some SMP
situations.

The mutex objects use the owner field of the thread queues for the mutex
owner. Use this and add a deadlock detection to
_Thread_queue_Enqueue_critical() for thread queues with an owner.

This helps to detect
* double insert, append, prepend errors, and
* get from empty chain errors.

The _RBTree_Find() is no longer used in the score. Move it to sapi and
make it rtems_rbtree_find(). Move corresponding types and support
functions to sapi.

The _RBTree_Insert() is no longer used in the score. Move it to sapi
and make it rtems_rbtree_insert().

Move the safety check performed by
_CORE_mutex_Check_dispatch_for_seize() out of the performance critical
path and generalize it. Blocking on a thread queue with an unexpected
thread dispatch disabled level is illegal in all system states.
Add the expected thread dispatch disable level (which may be 1 or 2
depending on the operation) to Thread_queue_Context and use it in
_Thread_queue_Enqueue_critical().

This change adds rtems_printf and related functions and wraps the
RTEMS print plugin support into a user API. All references to the
plugin are removed and replaced with the rtems_printer interface.
Printk and related functions are made to return a valid number of
characters formatted and output.
The function attribute to check printf functions has been added
to rtems_printf and printk. No changes to remove warrnings are part
of this patch set.
The testsuite has been moved over to the rtems_printer. The testsuite
has a mix of rtems_printer access and direct print control via the
tmacros.h header file. The support for begink/endk has been removed
as it served no purpose and only confused the code base. The testsuite
has not been refactored to use rtems_printf. This is future work.

The _Objects_Information_table is statically initialized. So, we can
make it read-only.
|
|
|
|
|
|
| |
Remove unused supports_global parameter. Convert
_Objects_Initialize_information() to a macro to avoid use of
RTEMS_MULTIPROCESSING define for each caller.

Delete SCORE_INIT. This finally removes the
some.h:
#ifndef SOME_XYZ_EXTERN
#define SOME_XYZ_EXTERN extern
#endif
SOME_XYZ_EXTERN type xyz;
some_xyz.c:
#define SOME_XYZ_EXTERN
#include <some.h>
pattern in favour of
some.h:
extern type xyz;
some_xyz.c
#include <some.h>
type xyz;
