PM / sleep: fix device reference leak in test_suspend

2016-11-02T04:10:04Z

Make sure to drop the reference taken by class_find_device() after opening the RTC device. Fixes: 77437fd4e61f (pm: boot time suspend selftest) Signed-off-by: Johan Hovold Signed-off-by: Rafael J. Wysocki

PM / sleep: Enhance test_suspend option with repeat capability

2014-09-08T23:48:02Z

Enhanced test_suspend boot paramter to repeat tests multiple times, by adding optional repeat count. The new boot param syntax: test_suspend="mem|freeze|standby[,N]" Signed-off-by: Srinivas Pandruvada Signed-off-by: Rafael J. Wysocki

PM / sleep: Support freeze as test_suspend option

2014-09-08T23:48:01Z

Added freeze as one of the option for test_suspend boot param. Signed-off-by: Srinivas Pandruvada Signed-off-by: Rafael J. Wysocki

PM / sleep: Fix test_suspend= command line option

2014-09-02T23:21:03Z

After commit d431cbc53cb7 (PM / sleep: Simplify sleep states sysfs interface code) the pm_states[] array is not populated initially, which causes setup_test_suspend() to always fail and the suspend testing during boot doesn't work any more. Fix the problem by using pm_labels[] instead of pm_states[] in setup_test_suspend() and storing a pointer to the label of the sleep state to test rather than the number representing it, because the connection between the state numbers and labels is only established by suspend_set_ops().

PM / sleep: Simplify sleep states sysfs interface code

2014-07-21T11:41:33Z

Simplify the sleep states sysfs interface /sys/power/state code by redefining pm_states[] as an array of pointers to constant strings such that only the entries corresponding to valid states are set. Signed-off-by: Rafael J. Wysocki

PM / sleep: Use valid_state() for platform-dependent sleep states only

2014-05-26T11:40:53Z

Use the observation that, for platform-dependent sleep states (PM_SUSPEND_STANDBY, PM_SUSPEND_MEM), a given state is either always supported or always unsupported and store that information in pm_states[] instead of calling valid_state() every time we need to check it. Also do not use valid_state() for PM_SUSPEND_FREEZE, which is always valid, and move the pm_test_level validity check for PM_SUSPEND_FREEZE directly into enter_state(). Signed-off-by: Rafael J. Wysocki

PM / sleep: Add state field to pm_states[] entries

2014-05-26T11:40:47Z

To allow sleep states corresponding to the "mem", "standby" and "freeze" lables to be different from the pm_states[] indexes of those strings, introduce struct pm_sleep_state, consisting of a string label and a state number, and turn pm_states[] into an array of objects of that type. This modification should not lead to any functional changes. Signed-off-by: Rafael J. Wysocki

driver-core: constify data for class_find_device()

2013-02-06T20:18:56Z

All in-kernel users of class_find_device() don't really need mutable data for match callback. In two places (kernel/power/suspend_test.c, drivers/scsi/osd/osd_uld.c) this patch changes match callbacks to use const search data. The const is propagated to rtc_class_open() and power_supply_get_by_name() parameters. Note that there's a dev reference leak in suspend_test.c that's not touched in this patch.

PM: Make warning in suspend_test_finish() less likely to happen

2009-10-21T23:23:45Z

Increase TEST_SUSPEND_SECONDS to 10 so the warning in suspend_test_finish() doesn't annoy the users of slower systems so much. Also, make the warning print the suspend-resume cycle time, so that we know why the warning actually triggered. Patch prepared during the hacking session at the Kernel Summit in Tokyo.

PM: Separate suspend to RAM functionality from core

2009-06-12T19:32:33Z

Move the suspend to RAM and standby code from kernel/power/main.c to two separate files, kernel/power/suspend.c containing the basic functions and kernel/power/suspend_test.c containing the automatic suspend test facility based on the RTC clock alarm. There are no changes in functionality related to these modifications. Signed-off-by: Rafael J. Wysocki Acked-by: Pavel Machek
