4. Get kms_flip basic test cases ..//kms_flip --list-subtests | grep -i basic >
<path location>
5. Execute igt test sudo -E ./run-tests.sh `cat <path location>` 
                or run one bye one
        $sudo -E ./run-tests.sh -t kms_flip at basic-plain-flip
        $sudo -E ./run-tests.sh-t kms_flip at basic-flip-vs-dpms
        $sudo -E ./run-tests.sh-t kms_flip at basic-flip-vs-modeset
        $sudo -E ./run-tests.sh-t kms_flip at basic-flip-vs-wf_vblank
