To dump stack of *any* (all) process you may write a little kld
wich will:
1) go through a process list,
2) get tf_eip, tf_esp, tf_ebp of a process
3) get p->p_vmspace
4) read process stack frames and all you need by manually
written routine based on procfs_rwmem and old good 'pread'
(which dosn't work now)
Another way is to go through proc list and coredump all the
processes for future manual analisys.
I like such way.
Can anybody point me to some difficults wich can appear while
implementing this?
