I am trying to debug a hang in our kext. I have been using gdb and the kgmacro command showallstacks to get a dump of all the stacks in the kernel. Using the output from showallstacks and the gdb list command, I can map the return address in every frame in every stack to a location in the source code (as long as it's in our driver).
What I would like to do is get a listing of each threads stack which included the parameters for each call. I would like something similar to the backtrace command, but for all stacks. Is this possible in gdb? Is it possible to get a list of the parameters for all the calls on a particular stack?
Thanks,
