* Introduce a way to make pure kernal threads.julian2007-10-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | kthread_add() takes the same parameters as the old kthread_create() plus a pointer to a process structure, and adds a kernel thread to that process. kproc_kthread_add() takes the parameters for kthread_add, plus a process name and a pointer to a pointer to a process instead of just a pointer, and if the proc * is NULL, it creates the process to the specifications required, before adding the thread to it. All other old kthread_xxx() calls return, but act on (struct thread *) instead of (struct proc *). One reason to change the name is so that any old kernel modules that are lying around and expect kthread_create() to make a process will not just accidentally link. fix top to show kernel threads by their thread name in -SH mode add a tdnam formatting option to ps to show thread names. make all idle threads actual kthreads and put them into their own idled process. make all interrupt threads kthreads and put them in an interd process (mainly for aesthetic and accounting reasons) rename proc 0 to be 'kernel' and it's swapper thread is now 'swapper' man page fixes to follow.
* - Move all of the PS_ flags into either p_flag or td_flags.jeff2007-09-171-2/+2
| | | | | | | | | | | | | | - p_sflag was mostly protected by PROC_LOCK rather than the PROC_SLOCK or previously the sched_lock. These bugs have existed for some time. - Allow swapout to try each thread in a process individually and then swapin the whole process if any of these fail. This allows us to move most scheduler related swap flags into td_flags. - Keep ki_sflag for backwards compat but change all in source tools to use the new and more correct location of P_INMEM.

* Rewrite the kludge-option processing to improve how it handles a fewgad2004-06-011-62/+91
| | | | | | | | | | | | | | | | | | | | more special situations. This is the code which process `ps blah', when "blah" does not include a leading '-'. This change also removes a long-undocumented BACKWARD_COMPATIBILITY compile-time option, where: ps -options arg1 arg2 (with no '-' on "arg1" and "arg2") was treated as: ps -options -N arg1 -M arg2 This also changes `ps' to check for any additional arguments after processing all the '-'-options, and attempt to use those arguments as a pid or pidlist. If an extra argument is not a valid pidlist, then `ps' will print an error and exit. This seems a more generally useful extension of the kludge-option processing than the -N/-M behavior, and has fewer confusing side-effects. Reviewed by: freebsd-arch
