* posix: Change pthread_once to be SMP safe.Chris Johns2013-08-142-0/+9
| | | | | | | | | | Change pthread_once from using disabled pre-emption to using a pthread mutex making it SMP safe. GCC using a posix threading model uses pthread_once. The pthread mutex requires at least 1 mutex is configured so confdefs.h has been updated to account for the internal mutex.

* Unlimited objects support for POSIX keysZhongwei Yao2013-08-061-5/+29
| | | | | | | This patch enables unlimited model in POSIX key manger and have a decent runtime on POSIX key searching, adding and deleting operations. Memory overhead is lower than current implementation when the size of key and key value becomes big.
* smp: Generalize _Thread_Start_multitasking()Sebastian Huber2013-08-051-2/+4
| | | | | | | | | | Add context parameter to _Thread_Start_multitasking() and use this function in rtems_smp_secondary_cpu_initialize(). This avoids duplication of code. Fix missing floating point context initialization in rtems_smp_secondary_cpu_initialize(). Now performed via _Thread_Start_multitasking().

* score: Error for non-preemptible tasks on SMPSebastian Huber2013-07-221-1/+5
| | | | | | | 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.

| | | | | | | | | | | | | 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.
* scheduler: New simple SMP scheduler implementationSebastian Huber2013-06-141-1/+1
| | | | | | | | | | | | | | | | | 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.
* score: Add and use _Objects_Put()Sebastian Huber2013-06-071-1/+1
| | | | | | 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.
* score: Remove idle field of Per_CPU_ControlSebastian Huber2013-05-312-4/+3
| | | | | | 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().
