Yes, definitely we should add some tests for measurements, not only for cpu hotplug but also for the other pm blocks. But I would like to postpone that as a separate test set focused on perf and measurements. Lava is waiting for "succeed", "fail", "skip" results, so adding numerical results will make the test suite to fail. I hope we can discuss at UDS-P about adding some perf tests and integrate them in lava. > It would also be interesting to know what happens when processes > pinned to a cpu have the cpu offlined underneath them. Right, I think it is the test David proposed. - -- <http://www.linaro.org/> Linaro.org │ Open source software for ARM SoCs Follow Linaro: <http://www.facebook.com/pages/Linaro> Facebook | <http://twitter.com/#!/linaroorg> Twitter | <http://www.linaro.org/linaro-blog/> Blog -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iQEcBAEBAgAGBQJOgxDdAAoJEAKBbMCpUGYAdvcH/iRg2bUU5E62LsyWx1yfvYtG hIdPQEI/ONUiukYk7eool8h5o5NmiAbDqHTQAJJCukJhA/ejPpmNOVeR+qf/XvNS VEvxUt/2U8b+420Novdw4Pl8CWR2TTSN9OT14npr1LEGOtOytfW6s5BRA/cfhwIC GIB/NT9Nim4QaUCI3bAK21mneEUsivaXuQa6ZndaJ/6qFiA9r9IidG/n8UwCBmuD S/8hksDjnLxb6pojRgAKbvP1g4M7oS/630JH4QT2/u2Z4el/UGEfePIz5xCvB/Zg EbeNPK8vmyD+1QrGgOJeVSiGHJovpogmoLXyXzh8nL5vaJR8vreAsPGLRBRxMqQ= =YU9j -----END PGP SIGNATURE----- _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
