These changes adds support for powerpc ppc64le to kvm-xfstests including building rootfs image. (Note: this requires latest qemu i.e. "qemu-system-ppc64 -machine help" should atleast support pseries-8.1) Here are the cmds which have been tested. 1. ~/src/tools/xfstests-bld/kernel-build/install-kconfig --arch ppc64le 2. ~/src/tools/xfstests-bld/kernel-build/kbuild --arch ppc64le 3. ~/src/tools/xfstests-bld/run-fstests/kvm-xfstests --arch ppc64le \ -N -o "fstesttyp=ext4" -n 4 -r 4096M -c 64k generic/001 -v 4. ./kvm-xfstests -N --kernel ~/src/linux/out-qemu/vmlinux --kernel-arch=ppc64le \ -o "fstesttyp=ext4" -n 4 -r 4096M -c 64k generic/001 -v 5. ./setup-buildchroot --arch=ppc64el && ./build-appliance --chroot=bookworm-ppc64el 6. On a linux build repo, we can directly use ~/src/tools/xfstests-bld/run-fstests/kvm-xfstests -c 4k,64k generic/001 7. On x86 it will default to tcg mode instead of kvm. <log> -------------------- Summary report KERNEL: kernel 6.6.0-rc1-next-20230913-xfstests-dirty #1 SMP Sat Oct 7 13:35:24 IST 2023 ppc64le CMDLINE: -c 4k,64k generic/001 CPUS: 2 MEM: 1982.81 ext4/4k: 1 tests, 3 seconds generic/001 Pass 3s ext4/64k: 1 tests, 5 seconds generic/001 Pass 4s Totals: 2 tests, 0 skipped, 0 failures, 0 errors, 7s Co-developed-by: Ojaswin Mujoo <ojaswin@linux.ibm.com> Signed-off-by: Ritesh Harjani (IBM) <ritesh.list@gmail.com> --- kernel-build/install-kconfig | 3 ++ kernel-build/kbuild | 9 ++++++ kernel-build/kernel-configs/ppc64le-config | 9 ++++++ run-fstests/kvm-xfstests | 35 +++++++++++++++++----- run-fstests/util/arch-funcs | 19 ++++++++++++ run-fstests/util/parse_cli | 5 ++++ run-fstests/util/parse_opt_funcs | 3 ++ 7 files changed, 76 insertions(+), 7 deletions(-) create mode 100644 kernel-build/kernel-configs/ppc64le-config
