Subject: [PATCH 2/4] KVM: selftests: Move "struct hv_enlightenments" to x86_64/svm.h
Date: Wed, 21 Sep 2022 20:16:05 +0000 [thread overview]
Message-ID: <20220921201607.3156750-3-seanjc@google.com> (raw)
In-Reply-To: <20220921201607.3156750-1-seanjc@google.com>
Move Hyper-V's VMCB "struct hv_enlightenments" to the svm.h header so
that the struct can be referenced in "struct vmcb_control_area".
Alternatively, a dedicated header for SVM+Hyper-V could be added, a la
x86_64/evmcs.h, but it doesn't appear that Hyper-V will end up needing
a wholesale replacement for the VMCB.
No functional change intended.
