Correct - the makefile and the whole glue code (and much else!)=20 comes from Git - see commits: 0780060: perf_counter tools: add in basic glue from Git d24e473: perf_counter: copy in Git's top Makefile Any suggestions about how best credit everyone there? One central=20 linux/tools/perf/CREDITS file? Ingo
