走天涯摘要：A system and method for using a toggle command for setting and releasing a lock, i.e. a locktoggle. In an exemplary computer system, one or more processors (110A; 110B) are each coupled to a bus bridge (130). The locktoggle command is used to transmit both a lock request and an unlock request from a processor (110A) to a system coherency point, e.g. the bus bridge (130). The system coherency point acknowledges when the lock has been established or released. While the lock is active, other processors are inhibited from accessing at least the memory locations for which the lock was initiated. Locks are thus established at the system coherency point, which may advantageously allow for locking functionality in a non-shared bus system. The use of the locktoggle command may advantageously allow for the use of a single command code point, leaving other points available for other uses.
