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.

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().
|
|
|
|
|
| |
Do not assume that the scheduler selects the main processor for the
initialization thread.

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().
|
|
|
|
|
| |
Rename open_dev_console() to rtems_libio_post_driver(). Rename
rtems_libio_supp_helper to rtems_libio_post_driver_helper.
|
|
|
|
|
| |
Add and use rtems_libio_helper function type. Add and use
rtems_libio_helper_null() instead of NULL pointer.

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.

This was not used by any BSP and obsolete now that unified memory
is an option for all BSPs.
