Here adds test support for big endian 64-bit PowerPC. The powernv machine of qemu-system-ppc64 is used with powernv_be_defconfig. As the document [1] shows: PowerNV (as Non-Virtualized) is the “bare metal” platform using the OPAL firmware. It runs Linux on IBM and OpenPOWER systems and it can be used as an hypervisor OS, running KVM guests, or simply as a host OS. Note, differs from little endian 64-bit PowerPC, vmlinux is used instead of zImage, because big endian zImage [2] only boot on qemu with x-vof=on (added from qemu v7.0) and a fixup patch [3] for qemu v7.0.51: [1]: https://qemu.readthedocs.io/en/latest/system/ppc/powernv.html [2]: https://github.com/linuxppc/issues/issues/402 [3]: https://lore.kernel.org/qemu-devel/20220504065536.3534488-1-aik@xxxxxxxxx/ Signed-off-by: Zhangjin Wu <falcon@xxxxxxxxxxx> --- tools/testing/selftests/nolibc/Makefile | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/tools/testing/selftests/nolibc/Makefile b/tools/testing/selftests/nolibc/Makefile index fbdf7fd9bf96..cced1d60ecf9 100644 --- a/tools/testing/selftests/nolibc/Makefile +++ b/tools/testing/selftests/nolibc/Makefile @@ -19,6 +19,7 @@ endif XARCH ?= $(or $(XARCH_$(ARCH)),$(ARCH)) # ARCH is supported by kernel +ARCH_powerpc64 = powerpc ARCH_powerpc64le = powerpc ARCH := $(or $(ARCH_$(XARCH)),$(XARCH)) @@ -30,6 +31,7 @@ IMAGE_arm64 = arch/arm64/boot/Image IMAGE_arm = arch/arm/boot/zImage IMAGE_mips = vmlinuz IMAGE_powerpc = vmlinux +IMAGE_powerpc64 = vmlinux IMAGE_powerpc64le= arch/powerpc/boot/zImage IMAGE_riscv = arch/riscv/boot/Image IMAGE_s390 = arch/s390/boot/bzImage @@ -45,6 +47,7 @@ DEFCONFIG_arm64 = defconfig DEFCONFIG_arm = multi_v7_defconfig DEFCONFIG_mips = malta_defconfig DEFCONFIG_powerpc = pmac32_defconfig +DEFCONFIG_powerpc64 = powernv_be_defconfig DEFCONFIG_powerpc64le= powernv_defconfig DEFCONFIG_riscv = defconfig DEFCONFIG_s390 = defconfig @@ -65,6 +68,7 @@ QEMU_ARCH_arm64 = aarch64 QEMU_ARCH_arm = arm QEMU_ARCH_mips = mipsel # works with malta_defconfig QEMU_ARCH_powerpc = ppc +QEMU_ARCH_powerpc64 = ppc64 QEMU_ARCH_powerpc64le= ppc64le QEMU_ARCH_riscv = riscv64 QEMU_ARCH_s390 = s390x @@ -79,6 +83,7 @@ QEMU_ARGS_arm64 = -M virt -cpu cortex-a53 -append "panic=-1 $(TEST:%=NOLIBC QEMU_ARGS_arm = -M virt -append "panic=-1 $(TEST:%=NOLIBC_TEST=%)" QEMU_ARGS_mips = -M malta -append "panic=-1 $(TEST:%=NOLIBC_TEST=%)" QEMU_ARGS_powerpc = -M g3beige -append "console=ttyS0 panic=-1 $(TEST:%=NOLIBC_TEST=%)" +QEMU_ARGS_powerpc64 = -M powernv -append "console=hvc0 panic=-1 $(TEST:%=NOLIBC_TEST=%)" QEMU_ARGS_powerpc64le= -M powernv -append "console=hvc0 panic=-1 $(TEST:%=NOLIBC_TEST=%)" QEMU_ARGS_riscv = -M virt -append "console=ttyS0 panic=-1 $(TEST:%=NOLIBC_TEST=%)" QEMU_ARGS_s390 = -M s390-ccw-virtio -m 1G -append "console=ttyS0 panic=-1 $(TEST:%=NOLIBC_TEST=%)" @@ -95,6 +100,7 @@ else Q=@ endif +CFLAGS_powerpc64 = -m64 -mbig-endian -mmultiple -Wl,-EB,-melf64ppc CFLAGS_powerpc64le = -m64 -mlittle-endian -Wl,-EL,-melf64ppc CFLAGS_s390 = -m64 CFLAGS_mips = -EL -- 2.25.1
