From 01d3240a04f4c09392e13c77b54d4423ebce2d72 Mon Sep 17 00:00:00 2001 From: Sean Young Date: Thu, 6 Dec 2018 13:01:03 +0000 Subject: media: bpf: add bpf function to report mouse movement Some IR remotes have a directional pad or other pointer-like thing that can be used as a mouse. Make it possible to decode these types of IR protocols in BPF.
