explorer 6b24c4b0fd Cleanup (in preparation for using gzip to estimate entropy) 
(1) remove unused and probably bad (from an API POV) ioctls,
(2) split tyfl into type and flags,
(3) collect an array of samples, and add them all at once.  Soon, this
    will be using gzip to estimate the entropy, but for now the original
    estimation methods are still used.
(4) kill rnd_add_data() -- it compliated the API for little benefit

drochner 0d46b0d0fd Make "1" an acceptable result in port tests. 
This is a workaround for crappy hardware, normal keyboard controllers
return a "0".
Should fix PR port-i386/6636 by Krister Walfridsson and problems
reported by chopps and fvdl.

fvdl c0fb2ab4f2 Use a SETRECURSE lock before calling VFS_MOUNT in the mount() system call, 
since the lock may be taken again. This was the intention of the CANRECURSE
lock already there, but didn't work.

Only fill in the vnode<->mountpoint links (mountedhere and vnodecovered)
after VFS_MOUNT returned succesfully. It might happen that something called
from VFS_MOUNT mistook the vnode for an already successfully mounted on
one because of this.

fvdl 09469c565c Define LK_SETRECURSE. 1999-02-28 14:09:45 +00:00
fvdl 080ad305ff Recursive locks were previously only available with LK_CANRECURSE. This 
could be done in one of 2 ways:

	* call lk_init with LK_CANRECURSE, resulting in a lock that
 	  always can be used recursively.
	* call lockmgr with LK_CANRECURSE, meaning that it's ok if this
	  lock is already held by us.

Sometimes we need a locking type that says: take this lock now, exclusively,
but while I am holding it, I may go through a code path which could attempt
to get the lock again, and which is unaware that the lock might already
be taken.  Implement LK_SETRECURSE for this purpose. Assume that locks and
unlocks come in matching pairs (they should), and check for this 'level'
using SETRECURSE locks.

thorpej 07304bd858 On multiprocessor systems, it is possible that a lev1map might be in use 
by two processors concurrently.  This means that we cannot modify the
lev1map in use by the processor which wishes to use the PROM.

Fix this by creating a separate lev1map for PROM users.  This lev1map
is a copy of the kernel_lev1map, with the exception of the necessary
PROM mapping.  When a processor wishes to use the PROM, it switches
its PTBR to point at the prom_lev1map, performs the PROM operation,
and switches back to its previous lev1map.

Note that kernels without multiprocessor support use the old method
of modifying the current lev1map.

Also, serialize access to the PROM via a spin lock.

thorpej 76e4555f2c Now that we have the kthread mechanism, massively clean up the way 
additional processors are spun up on multiprocessor Alpha systems.
Now, each processor gets its own idle thread (the primary processor
uses proc0).  This idle thread is used in switch_exit(), rather than
explicitly referencing proc0.

Also, make `curproc', `fpcurproc', and `curpcb' per-cpu values.  This
required some data structure rearrangement; cpu info is now statically
allocated in the BSS, rather than via malloc(), and cpu_softc is gone.
(Modeled somewhat after NetBSD/sparc's multiprocessor info structures.)

ross b4a33c4e60 Scheduler bug fixes and reorganization 
* fix the ancient nice(1) bug, where nice +20 processes incorrectly
  steal 10 - 20% of the CPU, (or even more depending on load average)
* provide a new schedclk() mechanism at a new clock at schedhz, so high
  platform hz values don't cause nice +0 processes to look like they are
  niced
* change the algorithm slightly, and reorganize the code a lot
* fix percent-CPU calculation bugs, and eliminate some no-op code

=== nice bug === Correctly divide the scheduler queues between niced and
compute-bound processes. The current nice weight of two (sort of, see
`algorithm change' below) neatly divides the USRPRI queues in half; this
should have been used to clip p_estcpu, instead of UCHAR_MAX.  Besides
being the wrong amount, clipping an unsigned char to UCHAR_MAX is a no-op,
and it was done after decay_cpu() which can only _reduce_ the value.  It
has to be kept <= NICE_WEIGHT * PRIO_MAX - PPQ or processes can
scheduler-penalize themselves onto the same queue as nice +20 processes.
(Or even a higher one.)

=== New schedclk() mechansism === Some platforms should be cutting down
stathz before hitting the scheduler, since the scheduler algorithm only
works right in the vicinity of 64 Hz. Rather than prescale hz, then scale
back and forth by 4 every time p_estcpu is touched (each occurance an
abstraction violation), use p_estcpu without scaling and require schedhz
to be generated directly at the right frequency. Use a default stathz (well,
actually, profhz) / 4, so nothing changes unless a platform defines schedhz
and a new clock.  Define these for alpha, where hz==1024, and nice was
totally broke.

=== Algorithm change === The nice value used to be added to the
exponentially-decayed scheduler history value p_estcpu, in _addition_ to
be incorporated directly (with greater wieght) into the priority calculation.
At first glance, it appears to be a pointless increase of 1/8 the nice
effect (pri = p_estcpu/4 + nice*2), but it's actually at least 3x that
because it will ramp up linearly but be decayed only exponentially, thus
converging to an additional .75 nice for a loadaverage of one. I killed
this, it makes the behavior hard to control, almost impossible to analyze,
and the effect (~~nothing at for the first second, then somewhat increased
niceness after three seconds or more, depending on load average) pointless.

=== Other bugs === hz -> profhz in the p_pctcpu = f(p_cpticks) calcuation.
Collect scheduler functionality. Try to put each abstraction in just one
place.

 available for cleanup, don't pass it around anymore where the
 "struct nfs_diskless" is already passed
-add a "cleanup" function which shuts the interface down
-in the protocol-specific parts, either return with "everything
 ready" or "completely shut down"
-use common functions for interface initialization and shutdown
-add a function to delete all routes associate to an interface

size prefixes around if the size of the operation is not explicitely
specified, even if the result is nonsense, eg for moves to segment
registers or control registers.
