* KVM: selftests: Move evmcs.h to x86_64/Vitaly Kuznetsov2021-06-171-1102/+0
| | | | | | | | | evmcs.h is x86_64 only thing, move it to x86_64/ subdirectory. Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <20210521095204.2161214-30-vkuznets@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
* KVM: selftests: Fix build for evmcs.hPeter Xu2020-05-061-2/+2
| | | | | | | | | | | | | | | | I got this error when building kvm selftests: /usr/bin/ld: /home/xz/git/linux/tools/testing/selftests/kvm/libkvm.a(vmx.o):/home/xz/git/linux/tools/testing/selftests/kvm/include/evmcs.h:222: multiple definition of `current_evmcs'; /tmp/cco1G48P.o:/home/xz/git/linux/tools/testing/selftests/kvm/include/evmcs.h:222: first defined here /usr/bin/ld: /home/xz/git/linux/tools/testing/selftests/kvm/libkvm.a(vmx.o):/home/xz/git/linux/tools/testing/selftests/kvm/include/evmcs.h:223: multiple definition of `current_vp_assist'; /tmp/cco1G48P.o:/home/xz/git/linux/tools/testing/selftests/kvm/include/evmcs.h:223: first defined here I think it's because evmcs.h is included both in a test file and a lib file so the structs have multiple declarations when linking. After all it's not a good habit to declare structs in the header files.

* KVM: selftests: define and use EVMCS_VERSIONVitaly Kuznetsov2020-03-161-0/+2
| | | | | | | | | | KVM allows to use revision_id from MSR_IA32_VMX_BASIC as eVMCS revision_id to workaround a bug in genuine Hyper-V (see the comment in nested_vmx_handle_enlightened_vmptrld()), this shouldn't be used by default. Switch to using KVM_EVMCS_VERSION(1). Signed-off-by: Vitaly Kuznetsov <vkuznets@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
