Subject: [RFC kvmtool 07/10] riscv: Define riscv specific vm_type function
Date: Wed, 19 Apr 2023 15:23:47 -0700 [thread overview]
Message-ID: <20230419222350.3604274-8-atishp@rivosinc.com> (raw)
In-Reply-To: <20230419222350.3604274-1-atishp@rivosinc.com>
RISC-V supports CoVE VMs now. It needs to setup correct VM type if the
user requests it.
