I try to use high resolution kernel profiling today on FreeBSD 4.6 release. I use config -p -p MYKERNEL and later kgmon -Br to start the profiling. However, the file generate by gprof contains many negative numbers such as -0.00, -0.02 under the columns of self and descendents. Why is the case? Does it mean we should not use high resolution profiling at all? Thanks for any enlightment. -Zhihui -- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
