Subject: [PATCH v8 06/12] target/riscv: Add support for hpmcounters/hpmevents
Date: Wed, 11 May 2022 14:59:50 -0700 [thread overview]
Message-ID: <20220511215956.2351243-7-atishp@rivosinc.com> (raw)
In-Reply-To: <20220511215956.2351243-1-atishp@rivosinc.com>
From: Atish Patra <atish.patra@wdc.com>
With SBI PMU extension, user can use any of the available hpmcounters to
track any perf events based on the value written to mhpmevent csr.
Add read/write functionality for these csrs.
