Date: Wed, 4 May 2022 22:48:53 +0000 From: Sean Christopherson <seanjc@...gle.com> To: Paolo Bonzini <pbonzini@...hat.com> Cc: linux-kernel@...r.kernel.org, kvm@...r.kernel.org, Vitaly Kuznetsov <vkuznets@...hat.com>, Andrew Jones <drjones@...hat.com>, David Matlack <dmatlack@...gle.com>, Ben Gardon <bgardon@...gle.com>, Oliver Upton <oupton@...gle.com>, Sean Christopherson <seanjc@...gle.com> Subject: [PATCH 107/128] KVM: selftests: Convert s390x/diag318_test_handler away from VCPU_ID Convert diag318_test_handler to use vm_create_with_vcpus() and pass around a 'struct kvm_vcpu' object instead of passing around vCPU IDs. Note, this is a "functional" change in the sense that the test now creates a vCPU with vcpu_id==0 instead of vcpu_id==6. 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.
