[PATCH v8 02/13] target/riscv: Fix the predicate functions for mhpmeventhX CSRs |
|
Date: |
Thu, 11 Jul 2024 15:31:05 -0700 |
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")
