Based on correlation with the enum for object lookup errors in
cpukit/score/include/rtems/score/objectimpl.h:
typedef enum {
OBJECTS_NAME_OR_ID_LOOKUP_SUCCESSFUL,
OBJECTS_INVALID_NAME,
OBJECTS_INVALID_ADDRESS,
OBJECTS_INVALID_ID,
OBJECTS_INVALID_NODE
} Objects_Name_or_id_lookup_errors;
update the comments regarding the object lookup error to status map to
match.

Add device spin-lock around internal data structures. Since the driver
provides a low-level C API accessing the descriptors the application
still needs to implement part of the SMP synchonization needed between
Interrupt handler and tasks.
Close#2355.
Thread priority changes may append or prepend the thread to its priority
group on the scheduler ready queue. Previously, a separate priority
value and a prepend-it flag in the scheduler node were used to propagate
a priority change to the scheduler.
Now, use an append-it bit in the priority control and reduce the plain
priority value to 63 bits.
This change leads to a significant code size reduction (about 25%) of
the SMP schedulers. The negligible increase of the standard priority
scheduler is due to some additional shift operations
(SCHEDULER_PRIORITY_MAP() and SCHEDULER_PRIORITY_UNMAP()).

Use the boot time to initialize the state. Use the state, the current
CPU counter and a very simple pseudo random number generator for
getentropy(). At least, this enables to pass the test "GETENTROPY 1" on
ERC32.
Update #3239.
If necessary, the BSP can now have it's clock and SDRAM initialization
in the SRAM instead of the SDRAM. This allows to change the clock
frequency during the startup of an SDRAM application.
We must not clear the priority updates in _Thread_queue_Extract_locked()
since this function is used by the priority ceiling surrender operations
after the ceiling priority handover from the previous owner to the new
owner. This is especially important in SMP configurations.
Move the _Thread_queue_Context_clear_priority_updates() invocation to
the callers.
Close#3237.
The thread queue extract operations performed by the
_Thread_queue_Flush_critical() may result in a priority change of the
thread queue owner. Carry out the scheduler priority update operation.
This is especially important in SMP configurations.
Close#3236.
The _Semaphore_Get_operations() must return the proper operations for
priority inheritance semaphores.
Add a test case for rtems_semaphore_flush() with priority inheritance.
Close#3235.
The watchdog routines invoked by the timer server may use mutexes for
synchronization. Ensure that the resource count of the timer server is
zero after each watchdog routine invocation. This helps to detect
broken watchdog routines.
The link time wrap of printf leads to unresolved symbols in the loadable
modules. This resulted in infinite loops and test timeouts. Use
rtems_printf() for output.
Update #3199.
SMP safe by spin-lock protection and semaphore. On spin-lock per SpW/AMBA
port to allow multiple parallel register operations per port. A common
semaphore for general SpW router configuration such as routing table.
Move to a C API instead of using the I/O Manager. The SpW router driver
does not perform any I/O only management of the router.
Update #2355.
- Remove the macro defines and the need for tmacro.h by remapping the
symbols using ld's wrap option.
- Remove FLUSH_OUTPUT, it was empty.
- Move rtems_test_exit to libmisc/testsupport as a function.
Update #3199.
Provide functions to get the version string, major, minor and revision
numbers and the version control identifer that is a unique tag for
the version control system.
Update #3199.
Remove POSIX_API_Control::created_with_explicit_scheduler. Add
Thread_Control::was_created_with_inherited_scheduler. This fixes also
pthread_getattr_np() for Classic tasks.
Update #2514.
In canonical mode, input is made available line by line. We must stop
the canonical buffer filling upon reception of an end-of-line character.
Close#3218.
