Hi everyone,
Following commit 13b25489b6f8 ("kbuild: change working directory to
external module directory with M="), the Makefiles for both bpf and hid
samples are broken due to the use of the relative vmlinux path (i.e.,
./vmlinux) when generating vmlinux.h. Additionally, samples/hid experience
the same problem that was fixed for samples/bpf in commit 5a6ea7022ff4
("samples/bpf: Remove unnecessary -I flags from libbpf EXTRA_CFLAGS").
This patchset makes the following changes to fix these two problems:
- It applies the same fix from commit 5a6ea7022ff4 ("samples/bpf: Remove
unnecessary -I flags from libbpf EXTRA_CFLAGS") to samples/hid.
- It replaces the relative vmlinux paths in samples/{bpf,hid}/Makefile
with $(objtree)/vmlinux to correctly refer to the kernel output
directory and vmlinux, following the recent working directory change in
kbuild.
Changelog:
v1 -> v2:
- v1: https://lore.kernel.org/all/20250120023027.160448-1-jinghao7@xxxxxxxxxxxx/
- Address feedback from Daniel
- Apply vmlinux path fix to samples/hid
- Add a second patch that fixes the include path issue in samples/hid,
i.e., the same issue fixed fpr samples/bpf in commit 5a6ea7022ff4
("samples/bpf: Remove unnecessary -I flags from libbpf EXTRA_CFLAGS").
- Address feedback from Masahiro and Nicolas
- Use $(objtree) instead of $(srctree) in the path when referring to
vmlinux, as it is an artifact of kbuild.
