Again, for a full explanation of HID-BPF, please refer to the last patch in this series (15/15). This revision contains most notably few fixes from the various kernel CI bots. I also took Alexei's review into account, and we do not pollute tools/include with useless hid headers. I also removed most of the last checkpatch complains about adding external kfunc declarations in C files. And this led me to also show in samples/ how we can link together 2 BPF object files. Impressive how easy it is :) Cheers, Benjamin Benjamin Tissoires (15): HID: fix I2C_HID not selected when I2C_HID_OF_ELAN is HID: Kconfig: split HID support and hid-core compilation HID: initial BPF implementation selftests: add tests for the HID-bpf initial implementation HID: bpf jmp table: simplify the logic of cleaning up programs HID: bpf: allocate data memory for device_event BPF programs selftests/hid: add test to change the report size HID: bpf: introduce hid_hw_request() selftests/hid: add tests for bpf_hid_hw_request HID: bpf: allow to change the report descriptor selftests/hid: add report descriptor fixup tests selftests/hid: Add a test for BPF_F_INSERT_HEAD samples/hid: add new hid BPF example samples/hid: add Surface Dial example Documentation: add HID-BPF docs Documentation/hid/hid-bpf.rst | 512 +++++++++++ Documentation/hid/index.rst | 1 + MAINTAINERS | 3 + drivers/Makefile | 2 +- drivers/hid/Kconfig | 18 +- drivers/hid/Makefile | 2 + drivers/hid/amd-sfh-hid/Kconfig | 2 +- drivers/hid/bpf/Kconfig | 17 + drivers/hid/bpf/Makefile | 11 + drivers/hid/bpf/entrypoints/Makefile | 93 ++ drivers/hid/bpf/entrypoints/README | 4 + drivers/hid/bpf/entrypoints/entrypoints.bpf.c | 34 + .../hid/bpf/entrypoints/entrypoints.lskel.h | 330 +++++++ drivers/hid/bpf/hid_bpf_dispatch.c | 531 +++++++++++ drivers/hid/bpf/hid_bpf_dispatch.h | 28 + drivers/hid/bpf/hid_bpf_jmp_table.c | 565 ++++++++++++ drivers/hid/hid-core.c | 34 +- drivers/hid/i2c-hid/Kconfig | 4 +- include/linux/hid.h | 5 + include/linux/hid_bpf.h | 163 ++++ samples/hid/.gitignore | 8 + samples/hid/Makefile | 250 ++++++ samples/hid/Makefile.target | 75 ++ samples/hid/hid_bpf_attach.bpf.c | 18 + samples/hid/hid_bpf_attach.h | 14 + samples/hid/hid_bpf_helpers.h | 21 + samples/hid/hid_mouse.bpf.c | 112 +++ samples/hid/hid_mouse.c | 155 ++++ samples/hid/hid_surface_dial.bpf.c | 134 +++ samples/hid/hid_surface_dial.c | 226 +++++ tools/testing/selftests/Makefile | 1 + tools/testing/selftests/hid/.gitignore | 4 + tools/testing/selftests/hid/Makefile | 233 +++++ tools/testing/selftests/hid/config | 20 + tools/testing/selftests/hid/hid_bpf.c | 845 ++++++++++++++++++ tools/testing/selftests/hid/progs/hid.c | 196 ++++ .../selftests/hid/progs/hid_bpf_helpers.h | 21 + 37 files changed, 4682 insertions(+), 10 deletions(-) create mode 100644 Documentation/hid/hid-bpf.rst create mode 100644 drivers/hid/bpf/Kconfig create mode 100644 drivers/hid/bpf/Makefile create mode 100644 drivers/hid/bpf/entrypoints/Makefile create mode 100644 drivers/hid/bpf/entrypoints/README create mode 100644 drivers/hid/bpf/entrypoints/entrypoints.bpf.c create mode 100644 drivers/hid/bpf/entrypoints/entrypoints.lskel.h create mode 100644 drivers/hid/bpf/hid_bpf_dispatch.c create mode 100644 drivers/hid/bpf/hid_bpf_dispatch.h create mode 100644 drivers/hid/bpf/hid_bpf_jmp_table.c create mode 100644 include/linux/hid_bpf.h create mode 100644 samples/hid/.gitignore create mode 100644 samples/hid/Makefile create mode 100644 samples/hid/Makefile.target create mode 100644 samples/hid/hid_bpf_attach.bpf.c create mode 100644 samples/hid/hid_bpf_attach.h create mode 100644 samples/hid/hid_bpf_helpers.h create mode 100644 samples/hid/hid_mouse.bpf.c create mode 100644 samples/hid/hid_mouse.c create mode 100644 samples/hid/hid_surface_dial.bpf.c create mode 100644 samples/hid/hid_surface_dial.c create mode 100644 tools/testing/selftests/hid/.gitignore create mode 100644 tools/testing/selftests/hid/Makefile create mode 100644 tools/testing/selftests/hid/config create mode 100644 tools/testing/selftests/hid/hid_bpf.c create mode 100644 tools/testing/selftests/hid/progs/hid.c create mode 100644 tools/testing/selftests/hid/progs/hid_bpf_helpers.h
