Subject: [PATCH memory-model scripts 07/31] tools/memory-model: Update parseargs.sh for hardware verification
Date: Mon, 20 Mar 2023 18:05:25 -0700 [thread overview]
Message-ID: <20230321010549.51296-7-paulmck@kernel.org> (raw)
In-Reply-To: <4e5839bb-e980-4931-a550-3548d025a32a@paulmck-laptop>
This commit adds a --hw argument to parseargs.sh to specify the CPU
family for a hardware verification. For example, "--hw AArch64" will
specify that a C-language litmus test is to be translated to ARMv8 and
the result verified. This will set the LKMM_HW_MAP_FILE environment
variable accordingly. If there is no --hw argument, this environment
variable will be set to the empty string.
