Subject: [PATCH v2 9/9] member: use accelerated crc on riscv
Date: Fri, 12 Jul 2024 16:46:45 +0100 [thread overview]
Message-ID: <20240712154645.80622-10-daniel.gregory@bytedance.com> (raw)
In-Reply-To: <20240712154645.80622-1-daniel.gregory@bytedance.com>
When the RISC-V Zbc (carryless multiplication) extension is present, an
implementation of CRC hashing using hardware instructions is available.
Use it rather than jhash.
