We are iterating through each output while testing suspend. This results in extended execution time. In turn this leads to hitting CI enforced timeout. By default limit number of tested outputs to 2. Test each connected output when passing command-line parameter. v3->v4 - indent `case' at same level as switch (Mohammed) v2->v3 - remove blank line (Mohammed) - change output format of help string (Mohammed) v1->v2 - s/OUTPUT_LIMIT/SUSPEND_OUTPUT_LIMIT/ (Mohammed) - fix typos (Mohammed) - fix off-by-one error (Mohammed) Reviewed-by: Mohammed Thasleem <redacted> Signed-off-by: Michał Grzelak <redacted> --- tests/intel/kms_psr.c | 28 +++++++++++++++++++++++++++- 1 file changed, 27 insertions(+), 1 deletion(-)
