HID: bpf: fix bpf compilation with -fms-extensions

2026-01-07T14:03:48Z

Similar to commit 835a50753579 ("selftests/bpf: Add -fms-extensions to bpf build flags") and commit 639f58a0f480 ("bpftool: Fix build warnings due to MS extensions") The kernel is now built with -fms-extensions, therefore generated vmlinux.h contains types like: struct slab { .. struct freelist_counters; }; Use -fms-extensions and -Wno-microsoft-anon-tag flags to build bpf programs that #include "vmlinux.h" Signed-off-by: Benjamin Tissoires

HID: bpf: error on warnings when compiling bpf objects

2024-06-14T09:20:20Z

There is no real reasons to paper over warnings for such small programs. Link: https://lore.kernel.org/r/20240608-hid_bpf_struct_ops-v3-13-6ac6ade58329@kernel.org Signed-off-by: Benjamin Tissoires

HID: bpf: add first in-tree HID-BPF fix for the XPPen Artist 24

2024-05-07T13:38:53Z

This commit adds a fix for XPPen Artist 24 where the second button on the pen is used as an eraser. It's a "feature" from Microsoft, but it turns out that it's actually painful for artists. So we ship here a HID-BPF program that turns this second button into an actual button. Note that the HID-BPF program is not directly loaded by the kernel itself but by udev-hid-bpf[0]. But having the sources here allows us to also integrate tests into tools/testing/selftests/hid to ensure the HID-BPF program are actually tested.
