From 93d6ba0889d0247ac264172858ef57698c960464 Mon Sep 17 00:00:00 2001 From: Alexey Kharlamov Date: Tue, 9 Jan 2018 00:50:06 +0300 Subject: ec/lenovo/h8: Implement ACPI methods to set battery thresholds There are two known reverse-engineered ways to manage battery thresholds. This patch implements them and adds a way to enable them for different mainboards. Tested on W530 with 4.18.3-gentoo kernel and X220 with 4.20.11. Works fine with new Linux userspace API for controlling battery thresholds, available since 4.17. (/sys/class/power_supply/BAT0/charge_(start|stop)_threshold). The new API is supported by TLP (you might need to set NATACPI_ENABLE=1 in /etc/tlp.conf). tpacpi-bat works fine too.
