perf pmu-events: Fix missing "cpu_clk_unhalted.core" event
The events defined in pmu-events JSON are parsed and added into perf tool. For fixed counters, we handle the encodings between JSON and perf by using a static array fixed[]. But the fixed[] has missed an important event "cpu_clk_unhalted.core". For example, on the Tremont platform, [root@localhost ~]# perf stat -e cpu_clk_unhalted.core -a event syntax error: 'cpu_clk_unhalted.core' \___ parser error With this patch, the event cpu_clk_unhalted.core can be parsed. [root@localhost perf]# ./perf stat -e cpu_clk_unhalted.core -a -vvv ------------------------------------------------------------ perf_event_attr: type 4 size 112 config 0x3c sample_type IDENTIFIER read_format TOTAL_TIME_ENABLED|TOTAL_TIME_RUNNING disabled 1 inherit 1 exclude_guest 1 ------------------------------------------------------------ ...
