* score: Use common names for per-CPU variablesSebastian Huber2014-04-2215-183/+183
| | | | | | | | | | | | | | | | Use "cpu" for an arbitrary Per_CPU_Control variable. Use "cpu_self" for the Per_CPU_Control of the current processor. Use "cpu_index" for an arbitrary processor index. Use "cpu_index_self" for the processor index of the current processor. Use "cpu_count" for the processor count obtained via _SMP_Get_processor_count(). Use "cpu_max" for the processor maximum obtained by rtems_configuration_get_maximum_processors().

* score: Critical fix for SMPSebastian Huber2014-04-163-18/+21
| | | | | | The _Scheduler_SMP_Allocate_processor() and _Thread_Dispatch() exchange information without locks. Make sure we use the right load/store ordering.
* score: Add clustered/partitioned schedulingSebastian Huber2014-04-1520-91/+486
| | | | | | | | | | | | | | | Clustered/partitioned scheduling helps to control the worst-case latencies in the system. The goal is to reduce the amount of shared state in the system and thus prevention of lock contention. Modern multi-processor systems tend to have several layers of data and instruction caches. With clustered/partitioned scheduling it is possible to honour the cache topology of a system and thus avoid expensive cache synchronization traffic. We have clustered scheduling in case the set of processors of a system is partitioned into non-empty pairwise-disjoint subsets. These subsets are called clusters. Clusters with a cardinality of one are partitions. Each cluster is owned by exactly one scheduler instance.

* score: Task get/set affinitySebastian Huber2014-04-159-90/+243
| | | | | Make rtems_task_get_affinity() and rtems_task_set_affinity() available on non-SMP configurations. Allow larger CPU sets.
* score: Simplify thread control initializationSebastian Huber2014-04-1525-419/+200
| | | | | | | | | | | The thread control block contains fields that point to application configuration dependent memory areas, like the scheduler information, the API control blocks, the user extension context table, the RTEMS notepads and the Newlib re-entrancy support. Account for these areas in the configuration and avoid extra workspace allocations for these areas. This helps also to avoid heap fragementation and reduces the per thread memory due to a reduced heap allocation overhead.
* score: Static scheduler configurationSebastian Huber2014-04-1579-662/+867
| | | | | | Do not allocate the scheduler control structures from the workspace. This is a preparation step for configuration of clustered/partitioned schedulers on SMP.
* score: Add and use RTEMS_ZERO_LENGTH_ARRAYSebastian Huber2014-04-153-2/+9

* capture: Use ISR lock for SMP supportSebastian Huber2014-04-141-71/+72
|
* score: SMP initialization changesSebastian Huber2014-04-147-19/+85
| | | | | | | | | | | | | | | | | Add and use _CPU_SMP_Start_processor(). Add and use _CPU_SMP_Finalize_initialization(). This makes most _CPU_SMP_Initialize() functions a bit simpler since we can calculate the minimum value of the count of processors requested by the application configuration and the count of physically or virtually available processors in the high-level code. The CPU port has now the ability to signal a processor start failure. With the support for clustered/partitioned scheduling the presence of particular processors can be configured to be optional or mandatory. There will be a fatal error only in case mandatory processors are not present. The CPU port may use a timeout to monitor the start of a processor.

* rtems: Rename rtems_smp_get_current_processor()Sebastian Huber2014-04-114-7/+31
| | | | | | | Rename rtems_smp_get_current_processor() in rtems_get_current_processor(). Make rtems_get_current_processor() a function in uni-processor configurations to enable ABI compatibility with SMP configurations.
* rtems: Rename rtems_smp_get_processor_count()Sebastian Huber2014-04-115-6/+31
| | | | | | Rename rtems_smp_get_processor_count() in rtems_get_processor_count(). Make rtems_get_processor_count() a function in uni-processor configurations to enable ABI compatibility with SMP configurations.
* score: Statically initialize IO managerSebastian Huber2014-04-106-109/+18
| | | | | | | | | | | | This simplifies the RTEMS initialization and helps to avoid a memory overhead. The workspace demands of the IO manager were not included in the <rtems/confdefs.h> workspace size estimate. This is also fixed as a side-effect. Update documentation and move "Specifying Application Defined Device Driver Table" to the section end. This sub-section is not that important for the user. Mentioning this at the beginning may lead to confusion.
