selftests: add tests for the HID-bpf initial implementation The tests are pretty basic: - create a virtual uhid device that no userspace will like (to not mess up the running system) - attach a BPF prog to it - open the matching hidraw node - inject one event and check: * that the BPF program can do something on the event stream * can modify the event stream - add another test where we attach/detach BPF programs to see if we get errors Note: the Makefile is extracted from selftests/bpf so we can rebuild the libbpf and bpftool components from the current kernel tree without relying on system installed components.

selftests: hid: import hid-tools hid-core tests These tests have been developed in the hid-tools[0] tree for a while. Now that we have a proper selftests/hid kernel entry and that the tests are more reliable, it is time to directly include those in the kernel tree. I haven't imported all of hid-tools, the python module, but only the tests related to the kernel. We can rely on pip to fetch the latest hid-tools release, and then run the tests directly from the tree. This should now be easier to request tests when something is not behaving properly in the HID subsystem.

selftests: add tests for the HID-bpf initial implementation The tests are pretty basic: - create a virtual uhid device that no userspace will like (to not mess up the running system) - attach a BPF prog to it - open the matching hidraw node - inject one event and check: * that the BPF program can do something on the event stream * can modify the event stream - add another test where we attach/detach BPF programs to see if we get errors Note: the Makefile is extracted from selftests/bpf so we can rebuild the libbpf and bpftool components from the current kernel tree without relying on system installed components.
