Userspace "s2ram" != PM_SUSPEND_MEM ("suspend-to-RAM") though. I'm not even sure there's a globally acceptable definition of what PM_SUSPEND_MEM indicates, beyond the fact that one expects it saves more power than PM_SUSPEND_STANDBY. Yes, the Documentation/power/states.txt regurgitates ACPI spec text. But lots of non-ACPI systems don't have any reason to do things like ACPI says. And in terms of latency, I've seen a lot of that be due to the PM framework taking so long to walk the device tree, with no substantial difference between "standby" and "str" costs. ------------------------------------------------------------------------- Take Surveys.
