kadb Macros

The kadb macros described below are particularly useful with the new multithreaded kernel.

thread displays the current thread. The current thread pointer is in SPARC global register g7.

kadb[0]: <g7$<thread

threadlist shows the stack traces of all the kernel threads in the system. This can be a long list.

kadb[0]: $<threadlist

mutex shows you the address of the owning thread. The following example uses the global unsafe driver mutex.

kadb[0]: unsafe_driver$<mutex

kadb[0]: moddebug/W 0x80000000

moddebug

moddebug enables you to watch module loading. See the end of <sys/modctl.h> for legal values for moddebug for debugging purposes only.
