2013-06-14scheduler: New simple SMP scheduler implementationSebastian Huber1-3/+3
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.
2013-06-14scheduler: Add and use _Scheduler_default_Tick()Sebastian Huber1-2/+2
Delete _Scheduler_priority_Tick(). Use _SMP_Get_processor_count() for default tick operation. Delete _Scheduler_simple_smp_Tick().
2013-06-14scheduler: Add start idle thread operationSebastian Huber1-0/+1
Add and use _Scheduler_Start_idle().
2013-06-14score: Rename rtems_smp_get_number_of_processors()Sebastian Huber1-3/+1
Rename in rtems_smp_get_processor_count(). Always provide <rtems/score/smp.h> and <rtems/rtems/smp.h>. Add _SMP_Get_processor_count(). This function will be a compile time constant defined to be one on uni-processor configurations. This allows iterations over all processors without overhead on uni-processor configurations.
2013-06-12score: Always provide <rtems/score/smplock.h>Sebastian Huber1-1/+1
2013-06-07score: Move thread dispatch content to new fileSebastian Huber1-0/+1
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.
2013-05-31smp: New SMP lock APISebastian Huber1-1/+1
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.

2012-11-22score: PR1607: Add and use CPU_SIZEOF_POINTERSebastian Huber1-0/+1
Add and use new CPU port define CPU_SIZEOF_POINTER. It must be an integer literal that can be used by the assembler. This value will be used to calculate offsets of structure members. These offsets will be used in assembler code. The size of a pointer is part of the application binary interface (ABI) and thus independent of the actual programming language. The compiler will provide defines to determine the current ABI. We use these defines to select the appropriate CPU_SIZEOF_POINTER value. Static assertions in the new file "cpukit/score/src/percpuasm.c" will ensure that the value of CPU_SIZEOF_POINTER is consistent with the current compiler settings. Also the offset values used by assembler code are verfied.
2012-11-22score: Inline _User_extensions_Thread_switch()Sebastian Huber1-2/+1

2012-11-13score: Add and use _User_extensions_Iterate()Sebastian Huber1-3/+1
Replace the separate user extension iterations with a single iteration function. This reduces code size and improves maintainability since the iteration logic is only in one function. The runtime overhead is insignificant.
2012-10-25score: Change _Heap_Extend() APISebastian Huber1-1/+1
The _Heap_Extend() has now the same signature as _Heap_Initialize(). The 4th parameter is ignored (page size in _Heap_Initialize()). Add Heap_Area and Heap_Initialization_or_extend_handler. Add and test _Heap_No_extend(). This helps to do a table based heap initialization and extension. Create a table of Heap_Area elements and iterate through it. Set the handler to _Heap_Initialize() in the first iteration and then to _Heap_Extend().
2012-08-06PR2069: [CBS Scheduler] Memory leak and enqueue problemAndreas Heinig1-0/+1
Due to the fact that CBS extends the EDF scheduler, most parts of EDF are reused. One part is the allocation of the per-thread data. However, the CBS per-thread structure defines a further element (while including the rest of Scheduler_EDF_Per_thread)

2012-02-10Added support functions for greedy heap allocationSebastian Huber1-1/+2
Various tests must check program paths that result due to failed memory allocations from the heap. To avoid tinkering with internal heap structures throughout the test code these functions should be used.
