Subject: [kvmtool PATCH v2 05/10] riscv: Add vector crypto extensions support
Date: Mon, 25 Mar 2024 21:01:36 +0530 [thread overview]
Message-ID: <20240325153141.6816-6-apatel@ventanamicro.com> (raw)
In-Reply-To: <20240325153141.6816-1-apatel@ventanamicro.com>
When the vector extensions are available expose them to the guest
via device tree so that guest can use it. This includes extensions
Zvbb, Zvbc, Zvkb, Zvkg, Zvkned, Zvknha, Zvknhb, Zvksed, Zvksh,
and Zvkt.
