[PATCH V4 0/3] KVM/Hyper-V: Add Hyper-V direct tlb flush support

2019-08-22 Thread lantianyu1986
From: Tianyu Lan This patchset is to add Hyper-V direct tlb support in KVM. Hyper-V in L0 can delegate L1 hypervisor to handle tlb flush request from L2 guest when direct tlb flush is enabled in L1. Patch 2 introduces new cap KVM_CAP_HYPERV_DIRECT_TLBFLUSH to enable feature from user space. User
