Subject: [PATCH v5 8/8] selftest: run vector prctl test for ZVE32X
Date: Fri, 10 May 2024 00:26:58 +0800 [thread overview]
Message-ID: <20240510-zve-detection-v5-8-0711bdd26c12@sifive.com> (raw)
In-Reply-To: <20240510-zve-detection-v5-0-0711bdd26c12@sifive.com>
The minimal requirement for running Vector subextension on Linux is
ZVE32X. So change the test accordingly to run prctl as long as it find
it.
