Abstract:
Techniques for implementing early acknowledgement for translation lookaside buffer (TLB) shootdowns are provided. In one set of embodiments, a first (i.e., remote) processing core of a computer system can receive an inter-processor interrupt (IPI) from a second (i.e., initiator) processing core of the computer system for performing a TLB shootdown of the first processing core. Upon receiving the IPI, an interrupt handler of the first processing core can communicate an acknowledgement to the second processing core that the TLB of the first processing core has been flushed, prior to actually flushing the TLB.
