docs: power: convert docs to ReST and rename to *.rst
Convert the PM documents to ReST, in order to allow them to
build with Sphinx.
The conversion is actually:
- add blank lines and indentation in order to identify paragraphs;
- fix tables markups;
- add some lists markups;
- mark literal blocks;
- adjust title markups.
At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Wysocki <rjw@sisk.pl>, GPL + +1. Preparing the test system +============================ + +Unfortunately, to effectively test the support for the system-wide suspend and +resume transitions in a driver, it is necessary to suspend and resume a fully +functional system with this driver loaded. Moreover, that should be done +several times, preferably several times in a row, and separately for hibernation +(aka suspend to disk or STD) and suspend to RAM (STR), because each of these +cases involves slightly different operations and different interactions with +the machine's BIOS. + +Of course, for this purpose the test system has to be known to suspend and +resume without the driver being tested. Thus, if possible, you should first +resolve all suspend/resume-related problems in the test system before you start +testing the new driver. Please see Documentation/power/basic-pm-debugging.rst +for more information about the debugging of suspend/resume functionality. + +2. Testing the driver +===================== + +Once you have resolved the suspend/resume-related problems with your test system +without the new driver, you are ready to test it: + +a) Build the driver as a module, load it and try the test modes of hibernation + (see: Documentation/power/basic-pm-debugging.rst, 1). + +b) Load the driver and attempt to hibernate in the "reboot", "shutdown" and + "platform" modes (see: Documentation/power/basic-pm-debugging.rst, 1). + +c) Compile the driver directly into the kernel and try the test modes of + hibernation. + +d) Attempt to hibernate with the driver compiled directly into the kernel + in the "reboot", "shutdown" and "platform" modes. + +e) Try the test modes of suspend (see: Documentation/power/basic-pm-debugging.rst, + 2). [As far as the STR tests are concerned, it should not matter whether or + not the driver is built as a module.] + +f) Attempt to suspend to RAM using the s2ram tool with the driver loaded + (see: Documentation/power/basic-pm-debugging.rst, 2). + +Each of the above tests should be repeated several times and the STD tests +should be mixed with the STR tests. If any of them fails, the driver cannot be +regarded as suspend/resume-safe. |
