Dragonboard410c OpenCSD

I want to run opencsd on dragonboard410c, refer to the link below:

1.The problem is that I don’t have a tools/perf directory when I ran the “make -C tools/perf” command.(according to the first link)
2.After entering the instruction according to the second link, it is inconsistent with the content displayed in the tutorial, and there is no CPU0 folder.

How should I operate to have the directory?
