Abstract: Embodiments of memory management in a multiprocessor system are disclosed. Embodiments include a system and method for maintaining translation lookaside buffer (TLB) consistency or coherency in a multiprocessor system. A coalescing component receives from a host system a list of TLB pages to be invalidated or purged. The coalescing component uses information of the TLB invalidation broadcast mechanism in use by a processor in the multiprocessor system to evaluate the list of TLB pages. The coalescing component generates a single TLB invalidation message with a variable invalidation range to cover multiple TLB pages of the list or the entire list of TLB pages to be invalidated, and the invalidation message is used to invalidate multiple TLB pages on multiple processors of the host system. Other embodiments are described and claimed.
