Subject: [PATCH 0/6] Refactor handling flow of SET_CPUID*
Date: Fri, 29 May 2020 16:55:39 +0800	[thread overview]
Message-ID: <20200529085545.29242-1-xiaoyao.li@intel.com> (raw)

This serial is the extended version of
https://lkml.kernel.org/r/20200528151927.14346-1-xiaoyao.li@intel.com

First two patches are bug fixing, and the other aim to refactor the flow
of SET_CPUID* as:
1. cpuid check: check if userspace provides legal CPUID settings;

2. cpuid update: Update some special CPUID bits based on current vcpu
                 state, e.g., OSXSAVE, OSPKE, ...

3. update KVM state: Update KVM states based on the final CPUID
                     settings. 

Xiaoyao Li (6):
  KVM: X86: Reset vcpu->arch.cpuid_nent to 0 if SET_CPUID fails
  KVM: X86: Go on updating other CPUID leaves when leaf 1 is absent
  KVM: X86: Introduce kvm_check_cpuid()
  KVM: X86: Split kvm_update_cpuid()
  KVM: X86: Move kvm_x86_ops.cpuid_update() into
    kvm_update_state_based_on_cpuid()
  KVM: X86: Move kvm_apic_set_version() to
    kvm_update_state_based_on_cpuid()
