Note that tuxmake does an in tree build of kselftest: make --silent --keep-going --jobs=8 O=/home/tuxbuild/.cache/tuxmake/builds/1/build INSTALL_PATH=/home/tuxbuild/.cache/tuxmake/builds/1/build/kselftest_install ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- CROSS_COMPILE_COMPAT=arm-linux-gnueabihf- 'CC=sccache aarch64-linux-gnu-gcc' 'HOSTCC=sccache gcc' kselftest-install and does it's own tarball build too, whereas kernelci does an out of tree build and uses kselftest-gen_tar: make KBUILD_BUILD_USER=KernelCI FORMAT=.xz ARCH=arm64 HOSTCC=gcc CROSS_COMPILE=aarch64-linux-gnu- CROSS_COMPILE_COMPAT=arm-linux-gnueabihf- CC="ccache aarch64-linux-gnu-gcc" O=/tmp/kci/linux/build -C/tmp/kci/linux -j10 kselftest-gen_tar and that the error is in the dt-extract-compatibles program which is part of the kernel (well, imported into the kernel from dtc upstream): File "/tmp/kci/linux/tools/testing/selftests/../../../scripts/dtc/dt-extract-compatibles", line 107, in compat_ignore_list.extend(parse_compatibles_to_ignore(f)) This all suggests that something to do with how the build is set up is resulting in the source symlink that gets created for out of tree builds blowing up, I guess it's not specifically the DT stuff that's blowing it up but rather that it's tripping over an existing bug. Really does look like a legitimate bug though, the source link is set up by the in tree kernel build infrastructure. I did poke a bit at reproducing outside of the KernelCI scripts but didn't manage to yet. --PzOuAaApHfvNPDUY Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmVD3hgACgkQJNaLcl1U h9CV1Af/XvDWEqs0dEvo3YSlq7hdCU87XwG4tii0WazqGAe4BTjhDtd9QMjkuiHa jbGSp4XI1Ip54USgUpM5MkQSXo2VAz+gAVSnK8Xv6OGHEbSS7ECve7ZUTBnyE7ld F6o2OIR3omBOfmdI8dXZbfemhcsBOMGzos8C1u/AmffeRtn7l75zyARxo2rsO5Dy 2Ljz9xf1g3U2hQySTGRRYpF4ZmsQcevnh3lFoh1mwV6rr2E6+05khAIbpTvGUDhL o0d8MBGvot0pxqdlciZi3LX1Hd6UPe66pHnpf8HDvi1OgM6QTrngIbuCM2tdrVp5 1QLv1gI2QfDJgR47QoV2AzS24XcHcw== =JKT+ -----END PGP SIGNATURE----- --PzOuAaApHfvNPDUY--
