clockrnd(9): Use atomic_load_relaxed for struct clockrnd::needed.

This may be set concurrently by clockrnd_get, so let's match the
atomic_store_relaxed and avoid the appearance of data races.

Improved the performance of kernel profiling on MULTIPROCESSOR, and possible to get profiling data for each CPU.

In the current implementation, locks are acquired at the entrance of the mcount
internal function, so the higher the number of cores, the more lock conflict
occurs, making profiling performance in a MULTIPROCESSOR environment unusable
and slow. Profiling buffers has been changed to be reserved for each CPU,
improving profiling performance in MP by several to several dozen times.

- Eliminated cpu_simple_lock in mcount internal function, using per-CPU buffers.
- Add ci_gmon member to struct cpu_info of each MP arch.
- Add kern.profiling.percpu node in sysctl tree.
- Add new -c <cpuid> option to kgmon(8) to specify the cpuid, like openbsd.
  For compatibility, if the -c option is not specified, the entire system can be
  operated as before, and the -p option will get the total profiling data for
  all CPUs.

entropy: Sample cycle counter or timecounter in hardclock.

Only do so when we're short on entropy, in order to minimize
performance impact.

The sampling should stay close to the time of the actual hardclock
timer interrupt, so that the oscillator driving it determines when we
sample the cycle counter or timecounter, which we hope is driven by
an independent oscillator.

If we used a callout, there might be many other influences -- such as
spin lock delays possibly synchronized with this core's cycle counter
-- that could get between the timer interrupt and the sample.

In the glorious tickless future, this should instead be wired up to
the timer interrupt handler, however that manifests in the future
tickless API.

Refactor interval timers to make it possible to support types other than
the BSD/POSIX per-process timers:

- "struct ptimer" is split into "struct itimer" (common interval timer
  data) and "struct ptimer" (per-process timer data, which contains a
  "struct itimer").

- Introduce a new "struct itimer_ops" that supplies information about
  the specific kind of interval timer, including it's processing
  queue, the softint handle used to schedule processing, the function
  to call when the timer fires (which adds it to the queue), and an
  optional function to call when the CLOCK_REALTIME clock is changed by
  a call to clock_settime() or settimeofday().

- Rename some fuctions to clearly identify what they're operating on
  (ptimer vs itimer).

- Use kmem(9) to allocate ptimer-related structures, rather than having
  dedicated pools for them.

Welcome to NetBSD 9.99.77.

Fix false sharing problems with cpu_info.  Identified with tprof(8).
This was a very nice win in my tests on a 48 CPU box.

- Reorganise cpu_data slightly according to usage.
- Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc).
- On x86, put some items in their own cache lines according to usage, like
  the IPI bitmask and ci_want_resched.

Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

 * Removes "options PERFCTRS", the associated includes, and the associated
   ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
   good.

 * Removes the PMC code of ARM XSCALE.

 * Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

 * Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
   definitions are put in sysarch.h.

 * Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
   and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
   netbsd32 and rump.

 * Removes the pmc_evid_t and pmc_ctr_t types.

 * Removes all the associated man pages. The sets are marked as obsolete.

adapt the cyclic module and profile dtrace provider to netbsd.
for now, just hook the cyclic callback into hardclock().

Back out previous; this should not be done in statclock but when the
allocations change or getrusage(). Plus the += seems wrong, we cannot
keep adding to the stats.

Actually return the computed uptime in microuptime().  Fixes many
wierd timing issues on non-timecounter ports (tested on sbmips, and
omap ARM by Marty Fouts).

Also move the microtime() inside the splclock() block in the same
function - it may be possible for the "time" variable to be updated
after the call to microtime() but before we use it to calculate the
offset from mono_time.

Merge scheduler changes from the vmlocking branch. All discussed on
tech-kern:

- Invert priority space so that zero is the lowest priority. Rearrange
  number and type of priority levels into bands. Add new bands like
  'kernel real time'.
- Ignore the priority level passed to tsleep. Compute priority for
  sleep dynamically.
- For SCHED_4BSD, make priority adjustment per-LWP, not per-process.

- Fix interactivity problems under high load. Beacuse soft interrupts
  are being stacked on top of regular LWPs, more often than not aston()
  was being called on a soft interrupt thread instead of a user thread,
  meaning that preemption was not happening on EOI.

- Don't use bool in a couple of data structures. Sub-word writes are not
  always atomic and may clobber other fields in the containing word.

- For SCHED_4BSD, make p_estcpu per thread (l_estcpu). Rework how the
  dynamic priority level is calculated - it's much better behaved now.

- Kill the l_usrpri/l_priority split now that priorities are no longer
  directly assigned by tsleep(). There are three fields describing LWP
  priority:

        l_priority: Dynamic priority calculated by the scheduler.
                This does not change for kernel/realtime threads,
                and always stays within the correct band. Eg for
                timeshared LWPs it never moves out of the user
                priority range. This is basically what l_usrpri
                was before.

        l_inheritedprio: Lent to the LWP due to priority inheritance
                (turnstiles).

        l_kpriority: A boolean value set true the first time an LWP
                sleeps within the kernel. This indicates that the LWP
                should get a priority boost as compensation for blocking.
                lwp_eprio() now does the equivalent of sched_kpri() if
                the flag is set. The flag is cleared in userret().

- Keep track of scheduling class (OTHER, FIFO, RR) in struct lwp, and use
  this to make decisions in a few places where we previously tested for a
  kernel thread.

- Partially fix itimers and usr/sys/intr time accounting in the presence
  of software interrupts.

- Use kthread_create() to create idle LWPs. Move priority definitions
  from the various modules into sys/param.h.

- newlwp -> lwp_create

Introduced nanotime() which is going to be used by some fs code yet to
be committed. This should really be an MD routine and microtime should
be implemented from it, not the opposite (which is what we have now).

Dynamic sysctl.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

New callout implementation.  This is based on callwheel implementation
done by Artur Grabowski and Thomas Nordin for OpenBSD, which is more
efficient in several ways than the callwheel implementation that it is
replacing.  It has been adapted to our pre-existing callout API, and
also provides the slightly more efficient (and much more intuitive)
API (adapted to the callout_*() naming scheme) that the OpenBSD version
provides.

Among other things, this shaves a bunch of cycles off rescheduling-in-
the-future a callout which is already scheduled, which the common case
for TCP timers (notably REXMT and KEEP).

The API has been simplified a bit, as well.  The (very confusing to
a good many people) "ACTIVE" state for callouts has gone away.  There
is now only "PENDING" (scheduled to fire in the future) and "EXPIRED"
(has fired, and the function called).

Kernel version bump not done; we'll ride the 1.6N bump that happened
with the malloc(9) change.

There's a locking order issue with the scheduler and the callwheel locks
as ltsleep() may call callout_reset() with the scheduler lock held.
So, prevent interrupts that may take the scheduler lock while holding
the callwheel lock.

Implement pmc(9) -- An interface to hardware performance monitoring
counters.  These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code

pmc(9) is meant to be a general interface.  Initially, the Intel XScale
counters are the only ones supported.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

Optimization suggested by Bill Sommerfeld:  Keep a hint as to the
"earliest" firing callout in a bucket.  This allows us to skip
the scan up the bucket if no callouts are due in the bucket.

A cheap O(1) hint update is done at callout insertion (if new callout
is earlier than hint) and removal (is bucket empty).  A thorough
refresh of the hint is done when the bucket is traversed.

This doesn't matter much on machines with small values of hz
(e.g. i386), but on systems with large values of hz (e.g. Alpha),
it has a definite positive effect.

Also, keep the callwheel stats in evcnts, so that you can view them
with "vmstat -e".

Introduce PROC_PC(), which is used to get a process's user PC.  If this is
defined, call addupc_intr() directly from statclock() in the system time case,
using the same P_OWEUPC path if the copyin/copyout fails.
Use this in i386 to remove profiling code from the normal userret() path.

More MP clock/scheduler changes:
 - Periodically invoke roundrobin() from hardclock() on all cpu's rather
than from a timer callout; this allows time-slicing on non-primary cpu's.
 - Make pscnt per-cpu.
 - Notice psdiv changes on each cpu, and adjust pscnt at that point.
Also, invoke setstatclockrate() from the clock interrupt when each cpu
notices the divisor change, rather than when starting/stopping the
profiling clock.

Change the semantics of splsoftclock() to be like other spl*() functions,
that is priority is rasied.  Add a new spllowersoftclock() to provide the
atomic drop-to-softclock semantics that the old splsoftclock() provided,
and update calls accordingly.

This fixes a problem with using the "rnd" pseudo-device from within
interrupt context to extract random data (e.g. from within the softnet
interrupt) where doing so would incorrectly unblock interrupts (causing
all sorts of lossage).

XXX 4 platforms do not have priority-raising capability: newsmips, sparc,
XXX sparc64, and VAX.  This platforms still have this bug until their

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.

Add NTP kernel precision timekeeping from Dave Mill's xntp distribution
and the "kernel.tar.Z" distribution on louie.udel.edu, which is older than
xntp 3.4y or 3.5a, but contains newer kernel source fragments.

This commit adds support for a new kernel configuration option, NTP.
If NTP is selected, then the system clock should be run at "HZ", which
must be defined at compile time to be one value from:
  60, 64, 100, 128, 256, 512, 1024.

Powers of 2 are ideal; 60 and 100 are supported but are marginally less
accurate.

If NTP is not configured, there should be no change in behavior relative
to pre-NTP kernels.

These changes have been tested extensively with xntpd 3.4y on a decstation;
almost identical kernel mods work on an i386.  No pulse-per-second (PPS)
line discipline support is included, due to unavailability of hardware
to test it.

With this in-kernel PLL support for NetBSD, both xntp 3.4y and xntp
3.5a user-level code need minor changes. xntp's prototype for
syscall() is  correct for FreeBSD, but not for NetBSD.

* ansifications
* cleaned up hardclock() to avoid checking "p" multiple times, and avoid a
  gcc2 possible-use-before-initialisation warning.
* changed softclock() timeout callback functions to be of type timeout_t -
  a pointer to a void fn(int).  No-one was using the second, tick, argument
  that was being passed to these callbacks - it is much cleaner to drop the
  thing entirely, rather than add a whole heap of casts of dubious
  correctness to calls to timeout(), etc.  The old style is kept in an
  #ifdef, for future reference.
