Subject: [RFC 35/48] RISC-V: KVM: Add TVM init/destroy calls
Date: Wed, 19 Apr 2023 15:17:03 -0700 [thread overview]
Message-ID: <20230419221716.3603068-36-atishp@rivosinc.com> (raw)
In-Reply-To: <20230419221716.3603068-1-atishp@rivosinc.com>
A TVM can only be created upon explicit request from the VMM via
the vm type if CoVE SBI extensions must supported by the TSM.
