I have a query about the FBT provider in DTrace, does FBT provider not need the CTF info for the /kernel binary...
I have this observation, when I disassemble say a 'kernel_funtion' , I see the function is not instrumented... (kgdb) disassemble kernel_function Dump of assembler code for function kernel_function: 0xc04aa05d <kernel_function+0>: push %ebp 0xc04aa05e <kernel_function+1>: mov %esp,%ebp 0xc04aa060 <kernel_function+3>: sub $0x2c,%esp Now after I did a 'fbt::kernel_function:entry', if I disassemble the 'kernel_function'... (kgdb) disassemble kernel_function Dump of assembler code for function kernel_function: 0xc04aa05d <kernel_function+0>: lock mov %esp,%ebp <== FBT instrumentation 0xc04aa060 <kernel_function+3>: sub $0x2c,%esp If I do a 'objdump' on the kernel.debug binary I do not see any CTF sections showing up? -- Shrikanth R K _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[email protected]"
