Features:
|
||||
|
||||
* beef up s2h to implement a battery watch loop: instead of entering
|
||||
hibernation unconditionally after coming back from resume make a decision
|
||||
based on the battery load level: if battery level is above a specific
|
||||
threshold, go to suspend again, only hibernate if below it. This means we'd
|
||||
stick to suspend usually, but fall back to hibernation only when battery runs
|
||||
empty (well, subject to our sampling interval). Related to this, check if we
|
||||
can make ACPI _BTP (i.e. /sys/class/power_supply/*/alarm) work for us too,
|
||||
i.e. see if it can wake up machines from suspend, so that we could resume
|
||||
automatically when the system is low on power and move automatically to
|
||||
hibernation mode. (see
|
||||
https://uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf
|
||||
section 10.2.2.8 and
|
||||
https://docs.microsoft.com/en-us/windows-hardware/design/device-experiences/modern-standby-wake-sources
|
||||
at the end).
|
||||
|
||||
* add an explicit "vertical" mode to format-table, so that "systemctl
|
||||
status"-like outputs (i.e. with a series of field names left and values
|
||||
right) become genuine first class citizens, and we gain automatic, sane JSON
