Subject: [PATCH v3 25/27] KVM: nVMX: Add FRED VMCS fields
Date: Mon, 30 Sep 2024 22:01:08 -0700	[thread overview]
Message-ID: <20241001050110.3643764-26-xin@zytor.com> (raw)
In-Reply-To: <20241001050110.3643764-1-xin@zytor.com>

From: Xin Li <xin3.li@intel.com>

Add FRED VMCS fields to nested VMX context management.

Signed-off-by: Xin Li <xin3.li@intel.com>
Signed-off-by: Xin Li (Intel) <xin@zytor.com>
Tested-by: Shan Kang <shan.kang@intel.com>
---

Change since v2:
* Add and use nested_cpu_has_fred(vmcs12) because vmcs02 should be set
  from vmcs12 if and only if the field is enabled in L1's VMX config
  (Sean Christopherson).
* Fix coding style (Sean Christopherson).

Change since v1:
* Remove hyperv TLFS related changes (Jeremi Piotrowski).
* Use kvm_cpu_cap_has() instead of cpu_feature_enabled() (Chao Gao).
