    perf pmu-events: Fix missing "cpu_clk_unhalted.core" event · 805ed210
    Jin Yao 提交于
    [ Upstream commit 8e6e5bea ]
    
    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
