perf record: Create two hybrid 'cycles' events by default
When evlist is empty, for example no '-e' specified in perf record, one default 'cycles' event is added to evlist. While on hybrid platform, it needs to create two default 'cycles' events. One is for cpu_core, the other is for cpu_atom. This patch actually calls evsel__new_cycles() two times to create two 'cycles' events. # ./perf record -vv -a -- sleep 1 ... ------------------------------------------------------------ perf_event_attr: size 120 config 0x400000000 { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|ID|CPU|PERIOD read_format ID disabled 1 inherit 1 freq 1 precise_ip 3 sample_id_all 1 exclude_guest 1 ------------------------------------------------------------ sys_perf_event_open: pid -1 cpu 0 group_fd -1 flags 0x8 = 5 sys_perf_event_open: pid -1 cpu 1 group_fd -1 flags 0x8 = 6 sys_perf_event_open: pid -1 cpu 2 group_fd -1 flags 0x8 = 7 sys_perf_event_open: pid -1 cpu 3 group_fd -1 flags 0x8 = 9 sys_perf_event_open: pid -1 cpu 4 group_fd -1 flags 0x8 = 10 sys_perf_event_open: pid -1 cpu 5 group_fd -1 flags 0x8 = 11 sys_perf_event_open: pid -1 cpu 6 group_fd -1 flags 0x8 = 12 sys_perf_event_open: pid -1 cpu 7 group_fd -1 flags 0x8 = 13 sys_perf_event_open: pid -1 cpu 8 group_fd -1 flags 0x8 = 14 sys_perf_event_open: pid -1 cpu 9 group_fd -1 flags 0x8 = 15 sys_perf_event_open: pid -1 cpu 10 group_fd -1 flags 0x8 = 16 sys_perf_event_open: pid -1 cpu 11 group_fd -1 flags 0x8 = 17 sys_perf_event_open: pid -1 cpu 12 group_fd -1 flags 0x8 = 18 sys_perf_event_open: pid -1 cpu 13 group_fd -1 flags 0x8 = 19 sys_perf_event_open: pid -1 cpu 14 group_fd -1 flags 0x8 = 20 sys_perf_event_open: pid -1 cpu 15 group_fd -1 flags 0x8 = 21 ------------------------------------------------------------ perf_event_attr: size 120 config 0x800000000 { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|ID|CPU|PERIOD read_format ID disabled 1 inherit 1 freq 1 precise_ip 3 sample_id_all 1 exclude_guest 1 ------------------------------------------------------------ sys_perf_event_open: pid -1 cpu 16 group_fd -1 flags 0x8 = 22 sys_perf_event_open: pid -1 cpu 17 group_fd -1 flags 0x8 = 23 sys_perf_event_open: pid -1 cpu 18 group_fd -1 flags 0x8 = 24 sys_perf_event_open: pid -1 cpu 19 group_fd -1 flags 0x8 = 25 sys_perf_event_open: pid -1 cpu 20 group_fd -1 flags 0x8 = 26 sys_perf_event_open: pid -1 cpu 21 group_fd -1 flags 0x8 = 27 sys_perf_event_open: pid -1 cpu 22 group_fd -1 flags 0x8 = 28 sys_perf_event_open: pid -1 cpu 23 group_fd -1 flags 0x8 = 29 ------------------------------------------------------------ We have to create evlist-hybrid.c otherwise due to the symbol dependency the perf test python would be failed.
