Subject: [PATCH v5 03/14] RISC-V: Improve SBI PMU extension related definitions
Date: Sat,  4 Feb 2023 17:15:04 -0800	[thread overview]
Message-ID: <20230205011515.1284674-4-atishp@rivosinc.com> (raw)
In-Reply-To: <20230205011515.1284674-1-atishp@rivosinc.com>

This patch fixes/improve few minor things in SBI PMU extension
definition.

1. Align all the firmware event names.
2. Add macros for bit positions in cache event ID & ops.

The changes were small enough to combine them together instead
of creating 1 liner patches.
