Author: avos Date: Sun Jan 13 02:19:01 2019 New Revision: 342981 URL: https://svnweb.freebsd.org/changeset/base/342981
Log: MFC r342810: powerd(8): allow to force a method of battery state query This change allows to determine power source via sysctl or /dev/apm when devd(8) is running (used by default). Based on patch from PR; other changes on top of it: - '-f' (force) -> '-s' (source) parameter renaming; - allow 'apm' -> 'devd' transition when '-s devd' is set (if APM is enabled); - man page update.
