* score: Create thread implementation headerSebastian Huber2013-07-261-437/+17
| | | | | | | | Move implementation specific parts of thread.h and thread.inl into new header file threadimpl.h. The thread.h contains now only the application visible API. Remove superfluous header file includes from various files.

* score: Changes due to Newlib __DYNAMIC_REENT__Sebastian Huber2013-07-171-0/+3
| | | | | | | | | | | | | 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 Huber2013-06-141-0/+28
| | | | | | | | | | | | | | | | | 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.
* scheduler: Add start idle thread operationSebastian Huber2013-06-141-1/+5
| | | | Add and use _Scheduler_Start_idle().
* score: Move thread dispatch content to new fileSebastian Huber2013-06-071-105/+0
| | | | | | | Move thread dispatch declarations and inline functions to new header <rtems/score/threaddispatch.h> to make it independent of the Thread_Control structure. This avoids a cyclic dependency in case thread dispatch functions are used for the object implementation.
* smp: New SMP lock APISebastian Huber2013-05-311-1/+8
| | | | | | | | | | | | | | Move the SMP lock implementation to the CPU port. An optimal SMP lock implementation is highly architecture dependent. For example the memory models may be fundamentally different. The new SMP lock API has a flaw. It does not provide the ability to use a local context for acquire and release pairs. Such a context is necessary to implement for example the Mellor-Crummey and Scott (MCS) locks. The SMP lock is currently used in _Thread_Disable_dispatch() and _Thread_Enable_dispatch() and makes them to a giant lock acquire and release. Since these functions do not pass state information via a local context there is currently no use case for such a feature.
