◆ baseAddr
| Addr gem5::prefetch::IndirectMemory::PrefetchTableEntry::baseAddr |
BaseAddr detected.

Referenced by gem5::prefetch::IndirectMemory::calculatePrefetch(), invalidate(), and gem5::prefetch::IndirectMemory::trackMissIndex2().
◆ enabled
| bool gem5::prefetch::IndirectMemory::PrefetchTableEntry::enabled |
Enable bit of the indirect fields.

Referenced by gem5::prefetch::IndirectMemory::calculatePrefetch(), invalidate(), and gem5::prefetch::IndirectMemory::trackMissIndex2().
◆ increasedIndirectCounter
| bool gem5::prefetch::IndirectMemory::PrefetchTableEntry::increasedIndirectCounter |
This variable is set to indicate that there has been at least one match with the current index value.
This information is later used when a new index is updated. If there were no increases in the indirectCounter, the counter is decremented.
