Andrei Vagin 281106f938 selftests: kvm: set rax before vmcall ... kvm_hypercall has to place the hypercall number in rax. Trace events show that kvm_pv_test doesn't work properly: kvm_pv_test-53132: kvm_hypercall: nr 0x0 a0 0x0 a1 0x0 a2 0x0 a3 0x0 kvm_pv_test-53132: kvm_hypercall: nr 0x0 a0 0x0 a1 0x0 a2 0x0 a3 0x0 kvm_pv_test-53132: kvm_hypercall: nr 0x0 a0 0x0 a1 0x0 a2 0x0 a3 0x0 With this change, it starts working as expected: kvm_pv_test-54285: kvm_hypercall: nr 0x5 a0 0x0 a1 0x0 a2 0x0 a3 0x0 kvm_pv_test-54285: kvm_hypercall: nr 0xa a0 0x0 a1 0x0 a2 0x0 a3 0x0 kvm_pv_test-54285: kvm_hypercall: nr 0xb a0 0x0 a1 0x0 a2 0x0 a3 0x0 Signed-off-by: Andrei Vagin <avagin@google.com> Message-Id: <20220722230241.1944655-5-avagin@google.com> Fixes: ac4a4d6de2 ("selftests: kvm: test enforcement of paravirtual cpuid features") Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>		2022-08-01 08:43:05 -04:00
