From 405ea445781ac27c7bb68bb27eec6086db7922c1 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 27 Sep 2021 15:59:37 +0200 Subject: [PATCH] ABI: sysfs-devices-power: document some RPM statistics Changeset 8d4b9d1bfef1 ("PM / Runtime: Add runtime PM statistics (v3)") added runtime_active_time and runtime_suspended_time, in order to allow powertop to identify the amount of time a device is active/suspended. Add an ABI description for those.
