perf vendor events intel: Fix Load_Miss_Real_Latency on SKL/SKX
Fix incorrect event names for the Load_Miss_Real_Latency metric for
Skylake and Skylake Server.
Fixes https://github.com/andikleen/pmu-tools/issues/158
Before:
% perf stat -M Load_Miss_Real_Latency true
event syntax error: '..ss.pending,mem_load_retired.l1_miss_ps,mem_load_retired.fb_hit_ps}:W'
\___ parser error
Usage: perf stat [<options>] [<command>]
-M, --metrics <metric/metric group list>
monitor specified metrics or metric groups (separated by ,)
After:
% perf stat -M Load_Miss_Real_Latency true
Performance counter stats for 'true':
279,204 l1d_pend_miss.pending # 14.0 Load_Miss_Real_Latency
4,784 mem_load_uops_retired.l1_miss
15,188 mem_load_uops_retired.hit_lfb
