Hello When a process has a page fault and Linux swaps out a page from another process and give it to the page-faulting process. Typically a INVLPG is used to invalidate entries in the TLB. I would like to know whether INVLPG is global ( i.e. across all cores )? Thanks Xin -- To unsubscribe from this list: send the line "unsubscribe linux-8086" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
