18 Of course, for this purpose the test system has to be known to suspend and
20 resolve all suspend/resume-related problems in the test system before you start
21 testing the new driver. Please see Documentation/power/basic-pm-debugging.rst
27 Once you have resolved the suspend/resume-related problems with your test system
28 without the new driver, you are ready to test it:
30 a) Build the driver as a module, load it and try the test modes of hibernation
31 (see: Documentation/power/basic-pm-debugging.rst, 1).
34 "platform" modes (see: Documentation/power/basic-pm-debugging.rst, 1).
