1. 查看源码 perfboot.py( https://cs.android.com/android/platform/superproject/+/master:system/core/init/perfboot.py)里面有个"output_results(filename, record_list, tags)函数"，其中 Comments 部分说明的比较详细:
` # First, count the number of the values of each tag. # This is for dealing with events that occur multiple times. # For instance, boot_progress_preload_start and boot_progress_preload_end # are recorded twice on 64-bit system. One is for 64-bit zygote process # and the other is for 32-bit zygote process. ` |
