Hmmm... since this is for host/hypervisor TLB handling, this makes me think that we should always be setting the ASID valid bit with 0 for the ASID value in EDX[15:0] on all INVLPGB instructions in this series. Otherwise we will also be flushing any guest ASID TLB entries that match the conditions, when that isn't intended. Thanks, Tom > > Thx. >
