| |
The following series implements support within KVM for MSR-based features. The first patch creates the MSR-based feature framework used to retrieve the available MSR-based features. The second patch makes use of the framework to allow a guest to determine if the LFENCE instruction is serializing on AMD processors.
This series is based on the master branch of the KVM git tree.
https://git.kernel.org/pub/scm/virt/kvm/kvm.git
---
Changes from v2: - Moved back to initializing the MSR-based feature list in kvm_init_msr_list() (based on the kvm_x86_ops callback return code) - Removed the definition of KVM_GET_MSR and switched back to using KVM_GET_MSRS - Consolidated the documentation to group the ioctl usage and describe the usage specific to the version of the ioctl used.
