yes we should compare the results with some hard coded values or a reference test results. I don't know if it's possible to use the result of a previous tests sequence in order to make some comparisons et set a test has passed or failed ? >>> Then, you're right >>> that we must wait a bit before adding some functional tests which test >>> that sched_mc is working as expected (from a power saving point of >>> view) with sched_mc_power_savings=2 > > -----BEGIN PGP SIGNATURE----- > Version: GnuPG v1.4.11 (GNU/Linux) > Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ > > iQEcBAEBAgAGBQJOOl7mAAoJEAKBbMCpUGYATdMIAJ8lkSd5Rxw4iU/ta2GKMCnc > THA2/XdaS/lNXtdCIiQX1u1bIz9YGcRwQhnPA3oFJoDbRs/67EroNhoW8o7gwzk6 > F8AFhbqcjj3YdykJ5k3rxsxdZLnUnprANxc6PTujs/Xj9qKekZ/G0SPfACmfL2aG > oTSHXAQGBl8Pb0vojGOfLDmhOAM88l13Q9vnT2gq6zYbhfSgybGnuCaUQl+DZlCh > xiXFaDgFMVMfaw2XeJQsvlgo2MnxWxo86oMZFICgF01hhCeWc9U6GNtQB0OaaQON > 8UnP04DVCjkXn76F6zua6qVSRrw/GHklXYdKdIEAGlpFEElmhjhwRSUH6Z44/04= > =BuHj > -----END PGP SIGNATURE----- > _______________________________________________ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
