Represents a memory coherence group.
typedef struct OpaqueMPCoherenceID* MPCoherenceID;
A coherence group is the set of processors and other bus controllers that have cache-coherent access to memory. Mac OS 9 defines only one coherence group, which is all the processors that can access internal memory (RAM). Other coherence groups are possible; for example, a PCI card with its own memory and processors can comprise a coherence group.
Introduced with Multiprocessing Services 2.1.
