Scott, please ack.
Alex, you were right. I screwed up the patch description by inverting relax and tight terms :) It should have been more like this: KVM: PPC: e500mc: Enhance tlb invalidation condition on vcpu schedule On vcpu schedule, the condition checked for tlb pollution is too loose. The tlb entries of a vcpu are polluted (vs stale) only when a different vcpu within the same logical partition runs in-between. Optimize the tlb invalidation condition taking into account the lpid. -Mike _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
