Subject: [PATCH v2 06/14] target/riscv: Add cfg properties for Zvkn[c|g] extensions
Date: Thu, 26 Oct 2023 23:18:13 +0800 [thread overview]
Message-ID: <20231026151828.754279-7-max.chou@sifive.com> (raw)
In-Reply-To: <20231026151828.754279-1-max.chou@sifive.com>
Vector crypto spec defines the NIST algorithm suite related extensions
(Zvkn, Zvknc, Zvkng) combined by several vector crypto extensions.
