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.
Use _Objects_Get_local() for _Semaphore_Get_interrupt_disable() to get
rid of the location parameter. Move remote object handling to semaphore
MPCI support.
Rename _ISR_Disable() into _ISR_Local_disable(). Rename _ISR_Enable()
into _ISR_Local_enable(). Remove _Debug_Is_owner_of_giant().
This is a preparation to remove the Giant lock.
Update #2555.
Rename _ISR_Disable_without_giant() into _ISR_Local_disable(). Rename
_ISR_Enable_without_giant() into _ISR_Local_enable().
This is a preparation to remove the Giant lock.
Update #2555.
Replace _Thread_Disable_dispatch() with _Thread_Dispatch_disable().
Replace _Thread_Enable_dispatch() with _Thread_Dispatch_enable().
This is a preparation to remove the Giant lock.
Update #2555.
Add _Thread_Change_life_locked() as a general function to alter the
thread life state. Use it to implement _Thread_Set_life_protection() as
a first step.
Update #2555.
Update #2626.
Added only for evaluation purposes. We have to compare the performance
against the ticket lock on the interesting platforms via
smptests/smplock01.
The following GCC shortcoming affects the MCS lock:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66867
The priority inheritance and ceiling CORE mutexes wrongly used the FIFO
queueing discipline. Delete misleading _CORE_mutex_Is_priority(). Bug
introduced by 1e1a91ed11.
Add test sptests/spmutex01, since no existing uni-processor test covered
the thread priority queueing discipline for CORE mutexes.
Account for the terminating null character. Use _POSIX_PATH_MAX instead
of NAME_MAX according to _POSIX_Semaphore_Manager_initialization() and
_POSIX_Message_queue_Manager_initialization().
The mq_open() function returns a descriptor to a POSIX message queue
object identified by a name. This is similar to sem_open(). In
contrast to the POSIX semaphore the POSIX message queues use a separate
object for the descriptor. This extra object is superfluous, since the
object identifier can be used directly for this purpose, just like for
the semaphores.
Update #2702.
Update #2555.
Remove unused supports_global parameter. Convert
_Objects_Initialize_information() to a macro to avoid use of
RTEMS_MULTIPROCESSING define for each caller.
Add a lock and use a chain iterator for safe iteration during concurrent
user extension addition and removal.
Ensure that dynamically added thread delete and fatal extensions are
called in reverse order.
Update #2555.
Update #2692.
POSIX key destructors must be called during thread restart. Just like
the POSIX cleanup handlers. This ensures that the TLS object
destructors are called during thread restart for example. It is
important for the global construction, which uses a thread restart to
run the Init task in a clean environment.
Close#2689.
