[PATCH] arm/arm64: KVM: Perform local TLB invalidation when multiplexing vcpus on a single CPU

Architecturally, TLBs are private to the (physical) CPU they're associated with. But when multiple vcpus from the same VM are being multiplexed on the same CPU, the TLBs are not private to the vcpus (and are actually shared across the VMID). Let's consider the following scenario: - vcpu-0 maps

Hi, I have a testcase which fails on host linux kernel 4.1.32. The testcase is that resetting the guest outside while rebooting inside at the same time. By the way, the guest kernel is linux 4.4 with debian filesystem. Here is the qemu command line: qemu-kvm \ -smp 4 \ -enable-kvm \
