Detailed Description

This group contains the implementation to support SMP systems.

This defines the interface of the SuperCore SMP support.

Macro Definition Documentation

_SMP_Get_current_processor

#define _SMP_Get_current_processor

(

)

Value:

UINT32_C(0)

_SMP_Get_processor_maximum

#define _SMP_Get_processor_maximum

(

)

Value:

UINT32_C(1)

_SMP_Handler_initialize

#define _SMP_Handler_initialize

(

void

)

Value:

do { } while ( 0 )

Initializes SMP Handler.

This method initialize the SMP Handler.

_SMP_Processor_configured_maximum

#define _SMP_Processor_configured_maximum   1

The configured processor maximum.

In SMP configurations, this constant is defined by the application configuration via <rtems/confdefs.h>, otherwise it is a compile-time constant with the value one.

_SMP_Request_shutdown

#define _SMP_Request_shutdown

(

void

)

Value:

do { } while ( 0 )

Requests a shutdown of all processors.

This function is a part of the system termination procedure.

See also

_Terminate().

_SMP_Request_start_multitasking

#define _SMP_Request_start_multitasking

(

void

)

Value:

do { } while ( 0 )

Requests a multitasking start on all configured and available processors.

SMP_MESSAGE_FORCE_PROCESSING

#define SMP_MESSAGE_FORCE_PROCESSING   0x4UL

SMP message to force the message processing in _SMP_Try_to_process_message().

This message bit is never sent to a processor. It is only used to force the message processing in _SMP_Try_to_process_message(). Any non-zero value would do it.

SMP_MESSAGE_PERFORM_JOBS

#define SMP_MESSAGE_PERFORM_JOBS   0x2UL

SMP message to perform per-processor jobs.

See also

_SMP_Send_message().

SMP_MESSAGE_SHUTDOWN

#define SMP_MESSAGE_SHUTDOWN   0x1UL

SMP message to request a processor shutdown.

See also

_SMP_Send_message().
