* score: Avoid SCORE_EXTERNSebastian Huber2016-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Delete SCORE_INIT. This finally removes the some.h: #ifndef SOME_XYZ_EXTERN #define SOME_XYZ_EXTERN extern #endif SOME_XYZ_EXTERN type xyz; some_xyz.c: #define SOME_XYZ_EXTERN #include <some.h> pattern in favour of some.h: extern type xyz; some_xyz.c #include <some.h> type xyz; Update #2559.

* score: _CPU_SMP_Get_current_processor()Sebastian Huber2014-02-211-2/+1
| | | | | | | Remove RTEMS_COMPILER_PURE_ATTRIBUTE from _SMP_Get_current_processor() and all _CPU_SMP_Get_current_processor(). Make inline ASM statements volatile again. Test smptests/smpmigration01 showed that GCC optimizes too much otherwise.
* score: Add and use <rtems/score/smpimpl.h>Sebastian Huber2014-02-191-64/+2
| | | | | Collect SMP implementation specific parts in the <rtems/score/smpimpl.h> header file.

* score: Rename RTEMS_BSP_SMP_SHUTDOWNSebastian Huber2014-02-191-6/+6
| | | | | Rename RTEMS_BSP_SMP_SHUTDOWN in SMP_MESSAGE_SHUTDOWN since SMP messages have nothing to do with the BSP. Use UINT32_C() instead of casts.
* score: Add RTEMS_FATAL_SOURCE_SMPSebastian Huber2014-02-191-0/+7
| | | | | | Use rtems_fatal() instead of _CPU_Fatal_halt() to shutdown processors in SMP configurations since this allows intervention of BSP or application specific fatal extensions.
* score: Move _SMP_Request_other_cores_to_shutdown()Sebastian Huber2014-02-191-3/+8
| | | | | | Move _SMP_Request_other_cores_to_shutdown() invocation from rtems_shutdown_executive() to _Internal_error_Occurred() to allow a proper shutdown on SMP configurations even in the error case.
* smp: Delete RTEMS_BSP_SMP_SIGNAL_TO_SELFSebastian Huber2013-08-211-7/+0
|
* smp: Delete _SMP_Request_other_cores_to_dispatch()Sebastian Huber2013-07-301-8/+0
| | | | | Use an event triggered unicast to inform remote processors about a necessary thread dispatch instead.
* smp: Add and use _CPU_SMP_Get_current_processor()Sebastian Huber2013-07-171-1/+11
| | | | | | | | | | Add and use _SMP_Get_current_processor() and rtems_smp_get_current_processor(). Delete bsp_smp_interrupt_cpu(). Change type of current processor index from int to uint32_t to match _SMP_Processor_count type.
* smp: Delete RTEMS_BSP_SMP_CONTEXT_SWITCH_NECESSARYSebastian Huber2013-07-171-7/+0
| | | | | The thread dispatch is a side-effect of interrupt processing, thus there is no need to send an explicit message.
* score: Rename rtems_smp_get_number_of_processors()Sebastian Huber2013-06-141-28/+32
| | | | | | | | | 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.
* smp: Simplify SMP initialization sequenceSebastian Huber2013-05-291-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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().
* cpukit: Doxygen group fixes and many warnings addressedJoel Sherrill2013-01-101-3/+3
| | | | | | | The output of the modules.html is much improved. Most filesystem and POSIX API related groups are properly nested. Some formatting issues were addressed as were multiple inconsistencies.

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-2/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
