From acaefd60493e265f1aefbc1b79d92367df6f676a Mon Sep 17 00:00:00 2001 From: Eric Lin Date: Wed, 12 Feb 2025 17:21:37 -0800 Subject: [PATCH] perf vendor events riscv: Add SiFive Bullet version 0x07 events SiFive Bullet microarchitecture cores with mimpid values starting with 0x07 or greater add new PMU events to support debug, trace, and counter sampling and filtering (Sscofpmf). All other PMU events are unchanged from earlier Bullet cores.
