Initial support is added for HiSilicon hip08 platform. Some sample usage on Huawei D06 board: $ ./perf list metric List of pre-defined events (to be used in -e): Metrics: bp_misp_flush [BP misp flush L3 topdown metric] branch_mispredicts [Branch mispredicts L2 topdown metric] core_bound [Core bound L2 topdown metric] divider [Divider L3 topdown metric] exe_ports_util [EXE ports util L3 topdown metric] fetch_bandwidth_bound [Fetch bandwidth bound L2 topdown metric] fetch_latency_bound [Fetch latency bound L2 topdown metric] fsu_stall [FSU stall L3 topdown metric] idle_by_icache_miss $ sudo ./perf stat -v -M core_bound sleep 1 Using CPUID 0x00000000480fd010 metric expr (exe_stall_cycle - (mem_stall_anyload + armv8_pmuv3_0@event\=0x7005@)) / cpu_cycles for core_bound found event cpu_cycles found event armv8_pmuv3_0/event=0x7005/ found event exe_stall_cycle found event mem_stall_anyload adding {cpu_cycles -> armv8_pmuv3_0/event=0x7001/ mem_stall_anyload -> armv8_pmuv3_0/event=0x7004/ Control descriptor is not initialized cpu_cycles: 989433 385050 385050 armv8_pmuv3_0/event=0x7005/: 19207 385050 385050 exe_stall_cycle: 900825 385050 385050 mem_stall_anyload: 253516 385050 385050 Performance counter stats for 'sleep': 989,433 cpu_cycles # 0.63 core_bound 19,207 armv8_pmuv3_0/event=0x7005/ 900,825 exe_stall_cycle 253,516 mem_stall_anyload 0.000805809 seconds time elapsed 0.000875000 seconds user 0.000000000 seconds sys perf stat --topdown is not supported, as this requires the CPU PMU to expose (alias) events for the TopDown L1 metrics from sysfs, which arm does not do. To get that to work, we probably need to make perf use the pmu-events cpumap to learn about those alias events. Metric reuse support is added for pmu-events parse metric testcase.
