函数名称：measure_l3_residency

函数原型：static int measure_l3_residency(void *_plr)

返回类型：int

参数：

类型参数名称
void *_plr
1087  plr等于_plr
1088  struct residency_counts counts = {0}
1100  当:x86_model恒等于INTEL_FAM6_BROADWELL_X
1102  Type specific configuration information.等于X86_CONFIG(.event = 0x2e, .umask = 0x4f)
1104  Type specific configuration information.等于X86_CONFIG(.event = 0x2e, .umask = 0x41)
1106  退出
1107  默认
1108  转到:out
1111  measure_residency_fn( & Create a perf_event_attr for the hit and miss perf events that will* be used during the performance measurement, & perf_hit_attr, plr, & counts)
1117  miss_after减等于miss_before
1118  如果x86_model恒等于INTEL_FAM6_BROADWELL_X则
1127  hits_after减等于hits_before
1129  hits_after减等于两数取小(miss_after, hits_after)
1130  否则
1131  hits_after减等于hits_before
1134  trace_pseudo_lock_l3(hits_after, miss_after)
1135  out :
1136  thread_done等于1
1137  wake_up_interruptible( & lock_thread_wq)
1138  返回:0
