H A DREADME8 The .bpf.c files provided here are not automatically compiled in the kernel.
9 They should be loaded in the kernel by `udev-hid-bpf`:
11 https://gitlab.freedesktop.org/libevdev/udev-hid-bpf
17 Once a .bpf.c file is accepted here, it is duplicated in `udev-hid-bpf`
18 in the `src/bpf/stable` directory, and distributions are encouraged to
19 only ship those bpf objects. So adding a file here should eventually
20 land in distributions when they update `udev-hid-bpf`
30 Just run `sudo udev-hid-bpf install ./my-awesome-fix.bpf.o`
34 - copy the `.bpf.o` you want in `/etc/udev-hid-bpf/`
37 The following should do the trick (assuming udev-hid-bpf is available in

H A Dbpftool-iter.rst35 A bpf iterator combines a kernel iterating of particular kernel data (e.g.,
36 tasks, bpf_maps, etc.) and a bpf program called for each kernel data object
40 The *pin* command creates a bpf iterator from *OBJ*, and pin it to *PATH*.
44 Map element bpf iterator requires an additional parameter *MAP* so bpf
45 program can iterate over map elements for that map. User can have a bpf
49 User can then *cat PATH* to see the bpf iterator output.
