Summary:A hybrid scheme is provided for performing translation lookaside buffer (TLB) shootdowns in a computer system whose processing cores support both inter-processor interrupt (IPI) and broadcast TLB invalidate (TLBI) shootdown mechanisms. In one set of embodiments, this hybrid scheme dynamically determines, for each instance where a TLB shootdown is needed, whether to use the IPI mechanism or the broadcast TLBI mechanism to optimize shootdown performance (or otherwise make the TLB shootdown operation functional/practical).
