Subject: [PATCH v1 7/8] selftests/nolibc: add test support for powerpc64le
Date: Wed, 19 Jul 2023 05:17:26 +0800 [thread overview]
Message-ID: <dbf7d642e2bce46e0023827cdd0e4438f8bf90e0.1689713175.git.falcon@tinylab.org> (raw)
In-Reply-To: <cover.1689713175.git.falcon@tinylab.org>
Here adds test support for little endian 64-bit PowerPC.
The powernv machine of qemu-system-ppc64le is used for there is just a
working powernv_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.
