selftests: kvm: return Kselftest Skip code for skipped tests

2018-08-03T05:47:40Z

[ Upstream commit ab0e9c4b91ca902b1cae593b3dec9c4c7a724f9f ] When kvm test is skipped because of unmet dependencies and/or unsupported configuration, it exits with error which is treated as a fail by the Kselftest framework. This leads to false negative result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Change it to use ksft_exit_skip() when the test is skipped. In addition, refine test_assert() message to include strerror() string and add explicit check for EACCES to cleary identify when test doesn't run when access is denied to resources required e.g: open /dev/kvm failed, rc: -1 errno: 13 Signed-off-by: Shuah Khan (Samsung OSG) Acked-by: Paolo Bonzini Signed-off-by: Shuah Khan (Samsung OSG) Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

KVM: selftests: exit with 0 status code when tests cannot be run

2018-05-11T09:21:12Z

Right now, skipped tests are returning a failure exit code if /dev/kvm does not exists. Consistently return a zero status code so that various scripts over the interwebs do not complain. Also return a zero status code if the KVM_CAP_SYNC_REGS capability is not present, and hardcode in the test the register kinds that are covered (rather than just using whatever value of KVM_SYNC_X86_VALID_FIELDS is provided by the kernel headers).

kvm: selftests: add vmx_tsc_adjust_test

2018-04-16T15:50:23Z

The test checks the behavior of setting MSR_IA32_TSC in a nested guest, and the TSC_OFFSET VMCS field in general. It also introduces the testing infrastructure for Intel nested virtualization. Signed-off-by: Paolo Bonzini
