https://bugzilla.kernel.org/show_bug.cgi?id=216176 --- Comment #5 from Hans de Goede (jwrdegoede@xxxxxxxxxxxxxxxxx) --- I agree that this should be a new userspace API under: /sys/class/power_supply/<BAT-name>/<some-sysfs-attribute> The best way to go about this is to first propose a new uAPI for this in the form of a patch to: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/ABI/testing/sysfs-class-power I think the best thing to do here is to add this as a 4th option to the /sys/class/power_supply/<supply_name>/charge_behaviour attribute: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/ABI/testing/sysfs-class-power#n462 All the modes there are exclusive (so only mode can be active at a time) and I think it would make sense to add a fast-charge option for this "rapid-charge" mode. Note for the driver patch that there are some helpers for implementing the charge_behaviour attribute: ssize_t power_supply_charge_behaviour_show(struct device *dev, unsigned int available_behaviours, enum power_supply_charge_behaviour behaviour, char *buf); int power_supply_charge_behaviour_parse(unsigned int available_behaviours, const char *buf); Notice the "unsigned int available_behaviours" this is a bit mask of supported modes from the enum power_supply_charge_behaviour. -- You may reply to this email to add a comment.
