Subject: [PATCH v3 0/2] KVM: MSR-based features
Date: Wed, 21 Feb 2018 13:39:41 -0600 [thread overview]
Message-ID: <20180221193941.12005.34137.stgit@tlendack-t1.amdoffice.net> (raw)
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.
