[PATCH 0/5] KVM: arm64: vcpu preempted check support
From: Zengruan Ye <yezengruan at huawei.com>
This patch set aims to support the vcpu_is_preempted() functionality
under KVM/arm64, which allowing the guest to obtain the vcpu is
currently running or not. This will enhance lock performance on
overcommitted hosts (more runnable vcpus than physical cpus in the
system) as doing busy waits for preempted vcpus will hurt system
performance far

[PATCH v2 0/6] KVM: arm64: VCPU preempted check support
This patch set aims to support the vcpu_is_preempted() functionality
under KVM/arm64, which allowing the guest to obtain the VCPU is
currently running or not. This will enhance lock performance on
overcommitted hosts (more runnable VCPUs than physical CPUs in the
system) as doing busy waits for preempted VCPUs will hurt system
performance far worse than early yielding.
