Structure defining a region.
Ptr SharedRegion_Entry::base |
The base address of the region.
SizeT SharedRegion_Entry::len |
The length of the region.
The length of a region must be the same across all processors in the system.
UInt16 SharedRegion_Entry::ownerProcId |
The MultiProc id of the owner of the region.
The owner id for a shared region must be the same across all processors in the system.
Bool SharedRegion_Entry::isValid |
Whether the region is valid.
Bool SharedRegion_Entry::cacheEnable |
Whether to perform cache operations for the region.
If 'TRUE', a cache invalidate is performed before any read and a cache write back invalidate is performed after any write for the shared region. The cache operations are done for all caches. If 'FALSE', no cache operations are performed.
SizeT SharedRegion_Entry::cacheLineSize |
The cache line size of the region.
The cache line size for a region must be the same across all processors in the system. It is used for structure alignment and padding.
Bool SharedRegion_Entry::createHeap |
Whether a heap is created for the region.
If 'TRUE', a HeapMemMP instance is created with the size spanning the length of the shared region minus any memory that is reserved in the region. If 'FALSE', no heap is created in the shared region.
String SharedRegion_Entry::name |
The name of the region.
The name must be in persistent memory. It is used for displaying in ROV.
