Subject: [PATCH 3/3] target/riscv: Fix the predicate functions for mhpmeventhX CSRs
Date: Mon, 29 Apr 2024 12:28:06 -0700 [thread overview]
Message-ID: <20240429-countinhibit_fix-v1-3-802ec1e99133@rivosinc.com> (raw)
In-Reply-To: <20240429-countinhibit_fix-v1-0-802ec1e99133@rivosinc.com>
mhpmeventhX CSRs are available for RV32. The predicate function
should check that first before checking sscofpmf extension.
Fixes: 14664483457b ("target/riscv: Add sscofpmf extension support")
