Subject: [PATCH v4 03/10] riscv: Make legacy counter enum match the HW numbering
Date:   Thu, 27 Jul 2023 16:14:21 +0200
Message-Id: <20230727141428.962286-4-alexghiti@rivosinc.com>
In-Reply-To: <20230727141428.962286-1-alexghiti@rivosinc.com>

RISCV_PMU_LEGACY_INSTRET used to be set to 1 whereas the offset of this
hardware counter from CSR_CYCLE is actually 2: make this offset match the
real hw offset so that we can directly expose those values to userspace.
