Hi, Willy
Most of the suggestions of v2 [1] have been applied in this v3 revision, except the local menuconfig and mrproper targets, as explained in [2].
A fresh run with tinyconfig for ppc, ppc64 and ppc64le:
$ for arch in ppc ppc64 ppc64le; do \ mkdir -p $PWD/kernel-$arch; time make defconfig run DEFCONFIG=tinyconfig ARCH=$arch O=$PWD/kernel-$arch RUN_OUT=$PWD/run.$arch.out; done
rerun for ppc, ppc64 and ppc64le:
$ for arch in ppc ppc64 ppc64le; do \ make rerun ARCH=$arch O=$PWD/kernel-$arch RUN_OUT=$PWD/run.$arch.out; done Running /labs/linux-lab/src/linux-stable/tools/testing/selftests/nolibc/kernel-ppc/vmlinux on qemu-system-ppc >> [ppc] Kernel command line: console=ttyS0 panic=-1 printk: console [ttyS0] enabled Run /init as init process Running test 'startup' Running test 'syscall' Running test 'stdlib' Running test 'vfprintf' Running test 'protection' Leaving init with final status: 0 reboot: Power down powered off, test finish qemu-system-ppc: terminating on signal 15 from pid 190248 ()

A fast report on existing test logs:

Changes from v2 --> v3:
* selftests/nolibc: allow report with existing test log selftests/nolibc: fix up O= option support selftests/nolibc: allow customize CROSS_COMPILE by architecture selftests/nolibc: customize CROSS_COMPILE for 32/64-bit powerpc selftests/nolibc: tinyconfig: add extra common options
No Change.
* selftests/nolibc: add macros to reduce duplicated changes
Remove REPORT_RUN_OUT and LOG_OUT.
* selftests/nolibc: string the core targets
Removed extconfig target from our v3 powerpc patchset [3], the operations have been merged into the defconfig target.
Let kernel depends on $(KERNEL_CONFIG) instead of the removed extconfig.
* selftests/nolibc: add menuconfig and mrproper for development
like the other local nolibc targets, still require local menuconfig and mrproper targets for consistent usage with the same ARCH and no -C /path/to/srctree
Merge them together to reduce duplicated entries.
* selftests/nolibc: allow quit qemu-system when poweroff fails
Enhance timeout logic with more expected strings print and detection about the booting of bios, kernel, init and test.
Add a default 10 seconds of QEMU_TIMEOUT for every architecture to detect all of the potential boog hang or failed poweroff.
* selftests/nolibc: customize QEMU_TIMEOUT for ppc64/ppc64le
Reduce QEMU_TIMEOUT from 60 seconds to a more normal 15 and 20 seconds for ppc64 and ppc64le respectively. the main time cost is the slow bios used.
* selftests/nolibc: tinyconfig: add support for 32/64-bit powerpc
Rename the file names to shorter ones as suggestions from the powerpc patchset.
* selftests/nolibc: speed up some targets with multiple jobs
New to speed up with -j<N> by default.
