Subject: [PATCH 0/1] RISC-V: kernel parameter for unaligned access speed
Date: Mon,  5 Aug 2024 13:38:16 -0400	[thread overview]
Message-ID: <20240805173816.3722002-2-jesse@rivosinc.com> (raw)
In-Reply-To: <20240805173816.3722002-1-jesse@rivosinc.com>

Add a kernel parameter to the unaligned access speed. This allows
skiping of the speed tests for unaligned accesses, which often is very
slow.

This patch requires (RISC-V: Detect and report speed of unaligned vector
accesses) to be applied first.
