HID-BPF Example and Fixup Programs

A set of small eBPF programs distributed with the kernel source that fix or tweak the report descriptors and event streams of specific human-interface devices, such as buggy mice, tablets, and keyboards. They are loaded on demand by userspace tools to correct device quirks without needing a dedicated kernel driver per device.

recommendation

This is not actually a driver directory; it is a collection of small eBPF programs that run alongside the HID subsystem to patch up quirky behaviour in specific input devices (mice, tablets, keyboards) without needing a full kernel driver. The programs are loaded into the kernel at runtime via the HID-BPF infrastructure rather than being compiled as hardware drivers themselves.

codex reasoning notes (technical)

Not a driver directory: contains HID BPF program sources under a `progs` subdirectory, which are eBPF/helper program code rather than a kernel-bound hardware driver.
