There is an ongoing work to enable PV TLB flushing for Hyper-V guests: http://driverdev.linuxdriverproject.org/pipermail/driverdev-devel/2017-April/104411.html it utilizes .flush_tlb_others member in pv_mmu_ops. hopefully, this work will be merged in 4.13. -- Vitaly _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
