Detailed Description

This handler encapsulates the primary definition of MPCI packets. This handler defines the part of the packet that is common to all remote operations.

Define Documentation

#define MP_PACKET_CLASSES_FIRST   MP_PACKET_MPCI_INTERNAL

This constant defines the first entry in the MP_packet_Classes enumeration.

#define MP_PACKET_CLASSES_LAST   MP_PACKET_SIGNAL

This constant defines the last entry in the MP_packet_Classes enumeration.

Referenced by _Mp_packet_Is_valid_packet_class().

#define MP_PACKET_MINIMUM_PACKET_SIZE   64

An MPCI must support packets of at least this size.

#define MP_PACKET_MINIMUN_HETERO_CONVERSION   ( sizeof( MP_packet_Prefix ) / sizeof( uint32_t ) )

The following constant defines the number of uint32_t 's in a packet which must be converted to native format in a heterogeneous system. In packets longer than MP_PACKET_MINIMUN_HETERO_CONVERSION uint32_t 's, some of the "extra" data may a user message buffer which is not automatically endian swapped.

Enumeration Type Documentation

enum MP_packet_Classes

The following enumerated type defines the packet classes.

Note:

In general, each class corresponds to a manager which supports global operations. Each manager defines the set of supported operations.

Function Documentation

RTEMS_INLINE_ROUTINE boolean _Mp_packet_Is_null

(

MP_packet_Prefix *

the_packet

)

This function returns TRUE if the the_packet_class is null, and FALSE otherwise.

RTEMS_INLINE_ROUTINE boolean _Mp_packet_Is_valid_packet_class

(

MP_packet_Classes

the_packet_class

)

This function returns TRUE if the the_packet_class is valid, and FALSE otherwise.

Note:

Check for lower bounds (MP_PACKET_CLASSES_FIRST ) is unnecessary because this enum starts at lower bound of zero.
