* score: Remove idle field of Per_CPU_ControlSebastian Huber2013-05-313-6/+15
| | | | | | 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().
* bsps: Use _Objects_Information_tableSebastian Huber2013-05-311-203/+134
| | | | | | Eliminate copy and paste. Use the _Objects_Information_table since this will take into account that more than one internal thread may exist, e.g. MPCI thread or idle threads of secondary processors.

* smp: Simplify SMP initialization sequenceSebastian Huber2013-05-295-104/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Delete bsp_smp_wait_for(). Other parts of the system work without timeout, e.g. the spinlocks. Using a timeout here does not make the system more robust. Delete bsp_smp_cpu_state and replace it with Per_CPU_State. The Per_CPU_State follows the Score naming conventions. Add _Per_CPU_Change_state() and _Per_CPU_Wait_for_state() functions to change and observe states. Use Per_CPU_State in Per_CPU_Control instead of the anonymous integer. Add _CPU_Processor_event_broadcast() and _CPU_Processor_event_receive() functions provided by the CPU port. Use these functions in _Per_CPU_Change_state() and _Per_CPU_Wait_for_state(). Add prototype for _SMP_Send_message(). Delete RTEMS_BSP_SMP_FIRST_TASK message. The first context switch is now performed in rtems_smp_secondary_cpu_initialize(). Issuing the first context switch in the context of the inter-processor interrupt is not possible on systems with a modern interrupt controller. Such an interrupt controler usually requires a handshake protocol with interrupt acknowledge and end of interrupt signals. A direct context switch in an interrupt handler circumvents the interrupt processing epilogue and may leave the system in an inconsistent state. Release lock in rtems_smp_process_interrupt() even if no message was delivered. This prevents deadlock of the system. Simplify and format _SMP_Send_message(), _SMP_Request_other_cores_to_perform_first_context_switch(), _SMP_Request_other_cores_to_dispatch() and _SMP_Request_other_cores_to_shutdown().
* smp: Delete bsp_smp_secondary_cpu_initialize()Sebastian Huber2013-05-293-8/+12
| | | | | | | Do not call bsp_smp_secondary_cpu_initialize() in rtems_smp_secondary_cpu_initialize(). This allows more flexibilty in the BSP low-level code. Specify context requirements for a call to rtems_smp_secondary_cpu_initialize().
* smp: Simplify main CPU initializationSebastian Huber2013-05-293-14/+8
| | | | | | 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.
* bsp/qoriq: Avoid NULL pointer accessSebastian Huber2013-05-271-5/+11
|
* bsps/arm: Add CLOCK_DRIVER_USE_FAST_IDLE optionSebastian Huber2013-05-272-0/+12
|
* bsps/arm: Move .fast_text sectionSebastian Huber2013-05-271-9/+9
| | | | | | | Move the .fast_text section after the .vector section. The .fast_test section is normally not empty in case some functions should execute from an internal SRAM. This would be also the area for the .vector section. The vector table must be the first content of such an area.
* bsps: Update due to linker changesSebastian Huber2013-05-278-170/+268
| | | | | | | In case the VMA and LMA regions differ, the LMA start address is now no longer aligned with the alignment of the input sections: http://sourceware.org/bugzilla/show_bug.cgi?id=15222
* smp: Add maximum_processors field to configSebastian Huber2013-05-162-7/+7
| | | | | | | 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().
