Hutterer: udev-hid-bpf: quickstart tooling to fix your HID devices with eBPF

Date:
Mon, 22 Apr 2024 14:44:00 +0000

Description:
Peter Hutterer announces
udev-hid-bpf , a tool to facilitate the loading of BPF programs that
make human-input devices work correctly. eBPF was originally written for 
network packet filters but as of
	kernel v6.3 and thanks to Benjamin, we have BPF in the HID
	subsystem. HID actually lends itself really well to BPF because,
	well, we have a byte array and to fix our devices we need to do
	complicated things like "toggle that bit to zero" or "swap those
	two values". See this article for more information on
the BPF-HID mechanism.
