Description

tp_smapi kernel module: https://github.com/evgeni/tp_smapi

SMAPI a useful feature for setting the battery charge threshold. The firmware part of SMAPI is implemented in the boot firmware (IMO the SMM part). Maybe we have to reverse engineer the factory firmware to know how the firmware code talk to the EC. We also need to change the cmos.layout of the supported laptops.
