Here's the general technique employed by the pid provider: each traced instruciton is first replaced with a trapping instruction. On sparc we use a ta (trap always) and on x86 (by which I mean i386 and amd64) we use an int3 (0xcc) (see the fasttrap_tracepoint_install() function in usr/src/uts/sparc/dtrace/fasttrap_isa.c and usr/src/uts/intel/dtrace/fasttrap_isa.c).
from this on sparc

This is really good information thank you for help, but as I read I found this module hooks for ta inserted in user level code. What I am looking for here is to hook say dbx (debugger something like int3 on x86) in place of this DTrace kernel module. how can we achieve it.
