Hi Bruce,
Resend a v2 patch, changes:
Add mainline commit id in patches log and using short commit from mainline
instead of linux-yocto in cover letter.
When we enable CONFIG_DEBUG_INFO and CONFIG_DEBUG_INFO_BTF option in yocto and
build the linux-yocto kernel again,
the error happens and the error message is about missing libelf.h and gelf.h in
tools/resolve_btfids source code.
The resolve_btfids needs a library named libelf, it contains in package
elfutils, and there is a limitation in
linux 5.15 kernel that when libelf was not installed in the standard
location(e.g /usr), it cannot be located
by the current building config.
So could you please help to merge those patches or cherry-pick the following
commits from linux-yocto 6.1 and
linux-yocto-dev to v5.15/standard/nxp-sdk-5.10/nxp-s32g and v5.15/standard/base:
commits from git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
mainline:
