Summary:A processor of an aspect includes a plurality of packed data registers, and a decode unit to decode a vector cache line write back instruction. The vector cache line write back instruction is to indicate a source packed memory indices operand that is to include a plurality of memory indices. The processor also includes a cache coherency system coupled with the packed data registers and the decode unit. The cache coherency system, in response to the vector cache line write back instruction, to cause, any dirty cache lines, in any caches in a coherency domain, which are to have stored therein data for any of a plurality of memory addresses that are to be indicated by any of the memory indices of the source packed memory indices operand, to be written back toward one or more memories. Other processors, methods, and systems are also disclosed.
