Dear all: In DTrace, when a fbt probe is activated, its related point (instruction) would be replaced with "int $3"(opcode: cc).
I refer to "Intel Architecuture Manual" and "Solaris Internals (2nd)", and find out that "int $3" is used for breakpoint. Then, when "int $3" is executed, what would happen? I mean, how does the kernel handle it? And... any recommended related articles? In the source code, what are the related functions and what are the related source files? TIA! Kind Regards, TJ
