http://perforce.freebsd.org/chv.cgi?CH=97463 Change 97463 by jb@jb_freebsd2 on 2006/05/19 20:29:01 It's time for the Function Boundary Tracing (FBT) provider. This one provides probes associated with the entry to and return from most functions kernel and kernel modules. The Solaris docs say: "even on the smallest Solaris systems, FBT will provide on the order of 20,000 probes." The advice from Sun was to port this provider before SDT, but I decided SDT was easier. 8-) Affected files ... .. //depot/projects/dtrace/src/sys/modules/dtrace/Makefile#16 edit .. //depot/projects/dtrace/src/sys/modules/dtrace/Makefile.inc#4 edit .. //depot/projects/dtrace/src/sys/modules/dtrace/fbt/Makefile#1 add Differences ... ==== //depot/projects/dtrace/src/sys/modules/dtrace/Makefile#16 (text+ko) ==== @@ -4,6 +4,7 @@ .include "Makefile.inc" SUBDIR= dtrace \ + fbt \ profile \ prototype \ sdt \ ==== //depot/projects/dtrace/src/sys/modules/dtrace/Makefile.inc#4 (text+ko) ==== @@ -4,6 +4,7 @@ -kldload cyclic -kldload dtrace -kldload sdt + -kldload fbt -kldload prototype -kldload profile -kldload systrace @@ -13,6 +14,7 @@ -kldunload systrace -kldunload profile -kldunload prototype + -kldunload fbt -kldunload sdt -kldunload dtrace -kldunload cyclic
