Linux 4.6 Adding Synaptics RMI4 To Better Handle Touchscreens, Touchpads

Written by Michael Larabel in Hardware on 19 March 2016 at 09:41 AM EDT. Add A Comment
There are a number of input driver improvements en route for the Linux 4.6 kernel.

Perhaps most significant about the input updates for Linux 4.6 is support for the Synaptics RMI4 protocol. RMI4 is the native protocol used by all current Synaptics devices including touchscreens and touchpads. The RMI4 support is there while in later Linux kernel releases they will switch devices to using RMI4 rather than HID/PS2 protocol emulation.

The input pull also has BYD PS/2 touchpad protocol support, MELFAS MIP4 touchscreen driver, and an assortment of other fixes. More details on the Linux 4.6 input updates can be found via this pull request.
