2022-06-11KVM: selftests: Convert evmcs_test away from VCPU_IDSean Christopherson1-26/+26
Convert evmcs_test to use vm_create_with_one_vcpu() and pass around a 'struct kvm_vcpu' object instead of using a global VCPU_ID. Note, this is a "functional" change in the sense that the test now creates a vCPU with vcpu_id==0 instead of vcpu_id==5. The non-zero VCPU_ID was 100% arbitrary and added little to no validation coverage. If testing non-zero vCPU IDs is desirable for generic tests, that can be done in the future by tweaking the VM creation helpers. Opportunistically use vcpu_run() instead of _vcpu_run(), the test expects KVM_RUN to succeed. Signed-off-by: Sean Christopherson <seanjc@google.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

Rename vm_create() to vm_create_barebones() and drop the @phys_pages param. Pass '0' for the number of pages even though some callers pass 'DEFAULT_GUEST_PHY_PAGES', as the intent behind creating truly barebones VMs is purely to create a VM, i.e. there aren't vCPUs, there's no guest code loaded, etc..., and so there is nothing that will ever need or consume guest memory. Freeing up the name vm_create() will allow using the name for an inner helper to the other VM creators, which need a "full" VM.

Consolidate the helper for retrieving the list of save/restore MSRs and the list of feature MSRs, and use the common helpers in the related get_msr_index_features test. Switching to the common helpers eliminates the testcase that KVM returns the same -E2BIG result if the input number of MSRs is '1' versus '0', but considered that testcase isn't very interesting, e.g. '0' and '1' are equally arbitrary, and certainly not worth the additional code.

Cache the list of MSRs to save restore, mostly to justify not freeing the list in the caller, which simplifies consumption of the list. Opportunistically move the XSS test's so called is_supported_msr() to common code as kvm_msr_is_in_save_restore_list(). The XSS is "supported" by KVM, it's simply not in the save/restore list because KVM doesn't yet allow a non-zero value.
