KVM: selftests: Fix build for evmcs.h

2020-05-27T15:48:12+00:00

[ Upstream commit 8ffdaf9155ebe517cdec5edbcca19ba6e7ee9c3c ]

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.

Add the basic infrastructure needed to test AMD nested SVM.
This is largely copied from the KVM unit test infrastructure.

selftests: KVM: Replace get_{gdt,idt}_base() by get_{gdt,idt}()

2020-02-12T19:09:38+00:00

get_gdt_base() and get_idt_base() only return the base address
of the descriptor tables. Soon we will need to get the size as well.
Change the prototype of those functions so that they return
the whole desc_ptr struct instead of the address field.

tools/x86: Sync msr-index.h from kernel sources

2020-01-13T16:42:57+00:00

Sync msr-index.h to pull in recent renames of the IA32_FEATURE_CONTROL
MSR definitions.  Update KVM's VMX selftest and turbostat accordingly.
Keep the full name in turbostat's output to avoid breaking someone's
workflow, e.g. if a script is looking for the full name.

While using the renamed defines is by no means necessary, do the sync
now to avoid leaving a landmine that will get stepped on the next time
msr-index.h needs to be refreshed for some other reason.

No functional change intended.
