Dear all: I've read most of the key code about dtrace, including dtrace(cmd), libdtrace, and dtrace(kernel module, and fbt, profile, etc). Since there're a lot of codes...I still feel puzzle about the module loading process.
When do dtrace modules loaded? After solaris started, checking through modinfo command, there're no dtrace modules in loaded module list. (no result report by "modinfo | grep Tracing") And then I try to use dtrace command to tracing something. After this, all the modules exist in module list now. I know dtrace module is loaded because dtrace cmd need to open dtrace module through the libdtrace. But when are the other modules (profile, systrace, fbt, etc) loaded? Who are the activator to load them? (I mean which function in uts/common/dtrace/dtrace.c will active these modules?) TIA Kind Regards, TJ
