Documentation: admin-guide: PM: Update sleep states documentation

2020-02-03T10:58:26Z

There is some information in Documentation/power/interface.rst that is still missing from Documentation/admin-guide/pm/sleep-states.rst and really should be present in there, so update the latter by adding that information to it and delete the former (as it becomes redundant after that and it is somewhat outdated). While at it, clean up some assorted pieces of sleep-states.rst a bit. Signed-off-by: Rafael J. Wysocki

intel_idle: Introduce 'states_off' module parameter

2020-02-03T10:57:18Z

In certain system configurations it may not be desirable to use some C-states assumed to be available by intel_idle and the driver needs to be prevented from using them even before the cpuidle sysfs interface becomes accessible to user space. Currently, the only way to achieve that is by setting the 'max_cstate' module parameter to a value lower than the index of the shallowest of the C-states in question, but that may be overly intrusive, because it effectively makes all of the idle states deeper than the 'max_cstate' one go away (and the C-state to avoid may be in the middle of the range normally regarded as available). To allow that limitation to be overcome, introduce a new module parameter called 'states_off' to represent a list of idle states to be disabled by default in the form of a bitmask and update the documentation to cover it.

intel_idle: Introduce 'use_acpi' module parameter

2020-02-03T10:57:08Z

For diagnostics, it is generally useful to be able to make intel_idle take the system's ACPI tables into consideration even if that is not required for the processor model in there, so introduce a new module parameter, 'use_acpi', to make that happen and update the documentation to cover it. While at it, fix the 'no_acpi' module parameter name in the documentation. Signed-off-by: Rafael J. Wysocki

Documentation: admin-guide: PM: Add intel_idle document

2020-01-15T09:54:58Z

Add an admin-guide document for the intel_idle driver to describe how it works: how it enumerates idle states, what happens during the initialization of it, how it can be controlled via the kernel command line and so on. Signed-off-by: Rafael J. Wysocki Reviewed-by: Randy Dunlap

cpuidle: Allow idle states to be disabled by default

2019-12-27T10:02:08Z

In certain situations it may be useful to prevent some idle states from being used by default while allowing user space to enable them later on. For this purpose, introduce a new state flag, CPUIDLE_FLAG_OFF, to mark idle states that should be disabled by default, make the core set CPUIDLE_STATE_DISABLED_BY_USER for those states at the initialization time and add a new state attribute in sysfs, "default_status", to inform user space of the initial status of the given idle state ("disabled" if CPUIDLE_FLAG_OFF is set for it, "enabled" otherwise).
