new header file semaphoreimpl.h. The semaphore.h contains now only the
application visible API.
A common use case for disabled preemption was to ensure mutual exclusion
on single-processor configurations. On SMP this does not work.
To abandon non-preemptible tasks simplifies the scheduler.
Add a configuration field which indicates if the SMP mode of operation
is enabled. This can be used to disable features unsupported on SMP,
e.g task variables.
Move implementation specific parts of mutex.h and mutex.inl into new
header file muteximpl.h. The mutex.h contains now only the application
visible API.
Delete _Thread_libc_reent and add __getreent() instead according to
__DYNAMIC_REENT__ define.
For SMP configurations __DYNAMIC_REENT__ must be defined.
A Newlib including the following patch is required:
2013-07-09 Sebastian Huber <sebastian.huber@embedded-brains.de>
* libc/include/sys/config.h (__DYNAMIC_REENT__): Define for RTEMS.
The new Simple SMP Scheduler allocates a processor for the processor
count highest priority ready threads. The thread priority and position
in the ready chain are the only information to determine the scheduling
decision. Threads with an allocated processor are in the scheduled
chain. After initialization the scheduled chain has exactly processor
count nodes. Each processor has exactly one allocated thread after
initialization. All enqueue and extract operations may exchange threads
with the scheduled chain. One thread will be added and another will be
removed. The scheduled and ready chain is ordered according to the
thread priority order. The chain insert operations are O(count of ready
threads), thus this scheduler is unsuitable for most real-time
applications.
The thread preempt mode will be ignored.
Add and use _Objects_Put_without_thread_dispatch(). These two functions
pair with the _Objects_Get() function. This helps to introduce object
specific SMP locks to avoid lock contention.
This field is unused except for special case simulator clock drivers.
In these places use an alternative. Add and use
_Thread_Set_global_exit_status() and _Thread_Get_global_exit_status().
Call _SMP_Handler_initialize() later and move bsp_smp_initialize() into
_SMP_Handler_initialize(). Change bsp_smp_initialize() prototype to
match integer types of calling context.
Delete rtems_configuration_get_smp_maximum_processors(). Delete
rtems_configuration_smp_maximum_processors variable. Add
maximum_processors field to rtems_configuration_table if RTEMS_SMP is
defined. Add rtems_configuration_get_maximum_processors().
Add and use rtems_libio_exit_helper. Add rtems_libio_exit().
The fclose(stdin) etc. makes no sense during exit. This would use the
_REENT structure of the thread calling _exit().
Only one of the following can be defined.
+ CONFIGURE_APPLICATION_NEEDS_CLOCK_DRIVER
+ CONFIGURE_APPLICATION_DOES_NOT_NEED_CLOCK_DRIVER
+ CONFIGURE_APPLICATION_NEEDS_TIMER_DRIVER
Otherwise it is a configuration error which can be detected at
compilation time.
The output of the modules.html is much improved. Most
filesystem and POSIX API related groups are properly nested.
Some formatting issues were addressed as were multiple
inconsistencies.
