Subject: [PATCH 00/11] KVM: x86: TDX preparation of introducing vm_type and blocking ioctls based on vm_type
Date: Fri, 12 Nov 2021 23:37:22 +0800 [thread overview]
Message-ID: <20211112153733.2767561-1-xiaoyao.li@intel.com> (raw)
This patchset is split from the TDX series[1].
It introduces vm_type for x86 at Patch 1, which leaves vaule 0 for normal
VM and adds a new type KVM_X86_TDX_VM for upcoming TDX guest. Following
patches (2, 4 - 11) block the ioctls that doesn't support for TDX from
userspace for TDX by checking the VM type.
Patch 3 is a cleanup.
Note, it doesn't block the ioctls for SEV-ES at all because I'm not sure
if each one applied to SEV-ES or not. Folks can introduce new vm_type for
SEV-* and extend each helper function kvm_xxx_feature_disallowed() for
SEV-* vm type.
Paolo,
Please let us know if you want this series sent together with whole
TDX support.
