| | | | | Simply annotate the function parameters with __unused, instead of adding the ve-variables. This makes the code build with GCC 4.7 and -Werror.

* Get rid of major/minor number distinction.ed2011-09-281-6/+2
| | | | | | | | | | | | | | | | | | | | | | As of FreeBSD 6, devices can only be opened through devfs. These device nodes don't have major and minor numbers anymore. The st_rdev field in struct stat is simply based a copy of st_ino. Simply display device numbers as hexadecimal, using "%#jx". This is allowed by POSIX, since it explicitly states things like the following (example taken from ls(1)): "If the file is a character special or block special file, the size of the file may be replaced with implementation-defined information associated with the device in question." This makes the output of these commands more compact. For example, ls(1) now uses approximately four columns less. While there, simplify the column length calculation from ls(1) by calling snprintf() with a NULL buffer. Don't be afraid; if needed one can still obtain individual major/minor numbers using stat(1).

* [1] When showing threads, the thread name just appears if the commattilio2009-02-261-2/+24
| | | | | | | | | | | | | | | | | | | label is choosen as last printout (ucomm suffers of this such bug too). That bug is caused by the fact that the fixed size of printout doesn't leave enough space for them to be printed out. Implement ucomm and comm commands with a dynamic size lenght for buffers. [2] On AMD64 architecture pointers don't have enough chars space to be shown (8 chars while they need 16). Fix them by providing a variadic space so that it fits well on both 64 and 32 bits architectures. [3] Check a return value of malloc() that wasn't checked before.

* Introduce a way to make pure kernal threads.julian2007-10-261-4/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.jeff2007-09-171-5/+4
| | | | | | | | | | | | | | - 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.
