SVN rev 191695 on 2009-04-30 17:35:44Z by jkim
General sleep state change clean up.
- Probe supported sleep states from acpi_attach() just once and do not
call AcpiGetSleepTypeData() again. It is redundant because
AcpiEnterSleepStatePrep() does it any way.
- Treat UNKNOWN sleep state as NONE, i.e., "do nothing", and remove obscure
NONE state (ACPI_S_STATES_MAX + 1) to avoid confusions.
- Do not set unsupported sleep states as default button/switch events.
If the default sleep state is not supported, just set it as UNKNOWN/NONE.
- Do not allow sleep state change if the system is not fully up and running.
This should prevent entering S5 state multiple times, which causes strange
behaviours later.
- Make sleep states case-insensitive when they are used with sysctl(8).
For example,
sysctl hw.acpi.lid_switch_state=s1
sysctl hw.acpi.sleep_button_state=none
are now legal and equivalent to the uppercase ones.
