Hi Zi,
When booting the kernel against next-master(20240228)with Arm64 on Marvell Thunder X2 (TX2), the kselftest-mm test 'split_huge_page_test' is failing in our CI (with rootfs over NFS). I can send the full logs if required.
A bisect (full log below) identified this patch as introducing the failure. Bisected it on the tag "next-20240228" at repo "https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git".
This works fine on Linux version 6.8.0-rc6
Hi Aishwarya,
I am trying to fix the issue. When I am compiling selftests/mm, I encountered the error below when I run make under the folder. Am I missing any configuration? Since you are able to run the test, I assume you know what is happening. Thanks.
for what its worth, I usually compile from the top level directory with:
# make headers_install # make -C tools/testing/selftests TARGETS=mm install INSTALL_PATH=~/kself
Perhaps the below is due to the headers not being exported properly. Bad things definitely happen if you omit the headers_install step.
