A system and method are provided for managing cache memory in a computer system. A cache controller portions a cache memory into a plurality of partitions, where each partition includes a plurality of physical cache addresses. Then, the method accepts a memory access message from the processor. The memory access message includes an address in physical memory and a domain identification (ID). A determination is made if the address in physical memory is cacheable. If cacheable, the domain ID is cross-referenced to a cache partition identified by partition bits. An index is derived from the physical memory address, and a partition index is created by combining the partition bits with the index. A processor is granted access (read or write) to an address in cache defined by partition index. |
