Subject: [PATCH v7 07/13] riscv: csr: Add CSR encodings for CSR_VXRM/CSR_VXSAT
Date: Wed, 24 Jul 2024 12:13:58 -0700	[thread overview]
Message-ID: <20240724-xtheadvector-v7-7-b741910ada3e@rivosinc.com> (raw)
In-Reply-To: <20240724-xtheadvector-v7-0-b741910ada3e@rivosinc.com>

The VXRM vector csr for xtheadvector has an encoding of 0xa and VXSAT
has an encoding of 0x9.
