Compiled and booted on my test system Lenovo P50s: Intel Core i7 No emergency and critical messages in the dmesg

I am a high school student and this is the first kernel I tested. Please let me know if you
would like to know more information about my test system or dmesg.

Thanks

hello,

There was a compilation error....

-----------x--------------x------------------x-- MODPOST vmlinux.symvers
MODINFO modules.builtin.modinfo
GEN modules.builtin
BTF: .tmp_vmlinux.btf: pahole (pahole) is not available Failed to generate BTF for vmlinux
Try to disable CONFIG_DEBUG_INFO_BTF
make: *** [Makefile:1183: vmlinux] Error 1

---------x--------------x-------------x---

i did CONFIG_DEBUG_INFO_BTF=n in .config and then compilation was success.

Compiled and booted 5.15.13-rc2+. dmesg gave no major problems.

Is this a regression? If so, what commit caused this?

Or you can install pahole, right? That's a requirement for that build option I think.

thanks,

Looks like some distros enabled this option - either disable the option or install pahole. Not a regression.

Keep in mind that CONFIG_DEBUG_INFO_BTF is a dependency to build bpf tests. bpf build pulls kernel defines from BTF to generate a header file. Not desirable to generate header that conflicts with standard libgcc defines which is not relevant to this conversation.

thanks,

i installed pahole which is in package "dwarves" in debian after reading yours and shuah's message

i agree with shuah's answer.
thanks shuah
