Subject: [PATCH] perf vendor events riscv: add StarFive Dubhe-80 JSON file
StarFive's Dubhe-80 supports raw event id 0x00 - 0x22.
The raw events are enabled through PMU node of DT binding.
Example of PMU DT node:
pmu {
compatible = "riscv,pmu";
riscv,raw-event-to-mhpmcounters =
/* Event ID 1-31 */
<0x00 0x00 0xFFFFFFFF 0xFFFFFFE0 0x00007FF8>,
/* Event ID 32-33 */
<0x00 0x20 0xFFFFFFFF 0xFFFFFFFE 0x00007FF8>,
/* Event ID 34 */
<0x00 0x22 0xFFFFFFFF 0xFFFFFF22 0x00007FF8>;
};
Example of Perf stat output:
[root@...r]# perf stat -a \
-e access_mmu_stlb \
-e miss_mmu_stlb \
-e access_mmu_pte_c \
-e rob_flush \
-e btb_prediction_miss \
-e itlb_miss \
-e sync_del_fetch_g \
-e icache_miss \
-e bpu_br_retire \
-e bpu_br_miss \
-e ret_ins_retire \
-e ret_ins_miss \
