Subject: [PATCH v10 07/14] riscv: csr: Add CSR encodings for CSR_VXRM/CSR_VXSAT
Date: Wed, 11 Sep 2024 22:55:15 -0700 [thread overview]
Message-ID: <20240911-xtheadvector-v10-7-8d3930091246@rivosinc.com> (raw)
In-Reply-To: <20240911-xtheadvector-v10-0-8d3930091246@rivosinc.com>
The VXRM vector csr for xtheadvector has an encoding of 0xa and VXSAT
has an encoding of 0x9.
