f9dff1f9fa Add support for 24/32 bit audio formats/conversion.
It may be the case that you may hear some unwanted noise while
playing back with 24/32 bit. This is a problem in the USB system.
Explanation from Hans Petter Selasky:
---snip---
The current USB sound driver only uses one isochronous
buffer, that is restarted when it is completed. This will lead to a short
period of time, +1ms, where no sound data is sent to the external USB device.
Depending on the load of your computer, this can be as much as 50ms. So the
USB sound driver must use 2 isochronous transfers. At the beginning one will
queue both. Then these are restarted on completion. This will result in a
constant-rate data stream to the external sound device, a minimum sound
buffer equal to the size of the isochronous buffer, and possibly the sound
will reach your ears with less delay. Little delay is a result of constant
data rate. Currently only my USB driver will support that. If one tries that
with the USB driver in *BSD, then it will crash at the first moment one gets
a buffer underrun.

d4426f281d Modify netstat -mb to use libmemstat when accessing a core dump or live
kernel memory and not using sysctl.  Previously, libmemstat was used
only for the live kernel via sysctl paths.

This results in netstat output becoming both more consistent between
core dumps and the live kernel, and also more information in the core
dump case than previously (i.e., mbuf cache information).

Statistics relating to sfbufs still rely on a kvm descriptor as they
are not currently exposed via libmemstat.  netstat -m operating on a
core is still unable to print certain sfbuf stats available on the live
kernel.

2c255e9df6 Moderate rewrite of kernel ktrace code to attempt to generally improve
reliability when tracing fast-moving processes or writing traces to
slow file systems by avoiding unbounded queueuing and dropped records.
Record loss was previously possible when the global pool of records
become depleted as a result of record generation outstripping record
commit, which occurred quickly in many common situations.

These changes partially restore the 4.x model of committing ktrace
records at the point of trace generation (synchronous), but maintain
the 5.x deferred record commit behavior (asynchronous) for situations
where entering VFS and sleeping is not possible (i.e., in the
scheduler).  Records are now queued per-process as opposed to
globally, with processes responsible for committing records from their
own context as required.

- Eliminate the ktrace worker thread and global record queue, as they
  are no longer used.  Keep the global free record list, as records
  are still used.

- Add a per-process record queue, which will hold any asynchronously
  generated records, such as from context switches.  This replaces the
  global queue as the place to submit asynchronous records to.

- When a record is committed asynchronously, simply queue it to the
  process.

- When a record is committed synchronously, first drain any pending
  per-process records in order to maintain ordering as best we can.
  Currently ordering between competing threads is provided via a global
  ktrace_sx, but a per-process flag or lock may be desirable in the
  future.

- When a process returns to user space following a system call, trap,
  signal delivery, etc, flush any pending records.

- When a process exits, flush any pending records.

- Assert on process tear-down that there are no pending records.

- Slightly abstract the notion of being "in ktrace", which is used to
  prevent the recursive generation of records, as well as generating
  traces for ktrace events.

Future work here might look at changing the set of events marked for
synchronous and asynchronous record generation, re-balancing queue
depth, timeliness of commit to disk, and so on.  I.e., performing a
drain every (n) records.

25efbfb212 Fixed some magic numbers.
The threshold for not being tiny was too small.  Use the usual 2**-12
threshold.  This change is not just an optimization, since the general
code that we fell into has accuracy problems even for tiny x.  Avoiding
it fixes 2*1366 args with errors of more than 1 ulp, with a maximum
error of 1.167 ulps.

The magic number 22 is log(DBL_EPSILON)/2 plus slop.  This is bogus
for float precision.  Use 9 (~log(FLT_EPSILON)/2 plus less slop than
for double precision).  The code for handling the interval
[2**-28, 9_was_22] has accuracy problems even for [9, 22], so this
change happens to fix errors of more than 1 ulp in about 2*17000
cases.  It leaves such errors in about 2*1074000 cases, with a max
error of 1.242 ulps.

The threshold for switching from returning exp(x)/2 to returning
exp(x/2)^2/2 was a little smaller than necessary.  As for coshf(),
This was not quite harmless since the exp(x/2)^2/2 case is inaccurate,
and fixing it avoids accuracy problems in 2*6 cases, leaving problems
in 2*19997 cases.

Fixed naming errors in pseudo-code in comments.

c24b7984fc Fixed some magic numbers.
The threshold for not being tiny was confusing and too small.  Use the
usual 2**-12 threshold and simplify the algorithm slightly so that
this threshold works (now use the threshold for sinhf() instead of one
for 1+expm1()).  This is just a small optimization.

The magic number 22 is log(DBL_EPSILON)/2 plus slop.  This is bogus
for float precision.  Use 9 (~log(FLT_EPSILON)/2 plus less slop than
for double precision).

The threshold for switching from returning exp(x)/2 to returning
exp(x/2)^2/2 was a little smaller than necessary.  This was not quite
harmless since the exp(x/2)^2/2 case is inaccurate.  Fixing it happens
to avoid accuracy problems for 2*6 of the 2*151 args that were handled
by the exp(x)/2 case.  This leaves accuracy problems for about 2*19997
args near the overflow threshold (~89); the maximum error there is
2.5029 ulps.

There are also accuracy probles for args in +-[0.5*ln2, 9] -- 2*188885
args with errors of more than 1 ulp, with a maximum error of 1.384 ulps.

Fixed a syntax error and naming errors in pseudo-code in comments.

d453d31b41 Instead of saving the unit number of the md(4) device name, save the
whole name. This does not unnecessarily close the door that in some
future we want to test on something other than md(4) devices.

Also add a "conf" action so that we can check whether a gctl actually
did the right thing or not. It's one thing to check that the result
strings are as expected, but it doesn't tell us if the end result is
correct. This needs a bit more fleshing out, but for now a visual
(i.e. manual) check suffices.

- Preserve existing method of calling mount() for UFS, until we clean things
  up.
- Preserve existing method of forking and calling external mount programs for
  mfs, msdosfs, nfs, nfs4, ntfs, nwfs, nullfs, portalfs, reiserfs, smbfs,
  udf, umapfs, unionfs
- devfs, linprocfs, procfs, ext2fs call nmount() syscall directly, since
  that is all those external mount programs were doing

d40f7f8b3e Make the kern.geom.conftxt sysctl more usable by also dumping the
MD class. Previously only the DISK class was dumped. The only
consumer of this sysctl is libdisk (i.e. sysinstall) and it tests
explicitly for instances of the DISK class. Dumping other classes
is therefore harmless.
By also dumping the MD class regression tests can be written that
use the MD class for operations that would normally be done on the
DISK class. The sysctl can now be used to test if those operations
took an effect. An example is partitioning.

d4a74de9fc As for the float trig functions, use a minimax polynomial that is
specialized for float precision.  The new polynomial has degree 8
instead of 14, and a maximum error of 2**-34.34 (absolute) instead of
2**-30.66.  This doesn't affect the final error significantly; the
maximum error was and is about 0.8879 ulps on amd64 -01.

The fdlibm expf() is not used on i386's (the "optimized" asm version
is used), but probably should be since it was already significantly
faster than the asm version on athlons.  The asm version has the
advantage of being more accurate, so keep using it for now.

71909edec8 Significant refactoring of the accounting code to improve locking and VFS
happiness, as well as correct other bugs:

- Replace notion of current and saved accounting credential/vnode with a
  single credential/vnode and an acct_suspended flag.  This simplifies the
  accounting logic substantially.

- Replace acct_mtx with acct_sx, a sleepable lock held exclusively during
  reconfiguration and space polling, but shared during log entry
  generation.  This avoids holding a mutex over sleepable VFS operations.

- Hold the sx lock over the duration of the I/O so that the vnode I/O
  cannot occur after vnode close, which could occur previously if
  accounting was disabled as a process exited.

- Write the accounting log entry with Giant conditionally acquired based
  on the file system where the log is stored.  Previously, the accounting
  code relied on the caller acquiring Giant.

- Acquire Giant conditionally in the accounting callout based on the file
  system where the accounting log is stored.  Run the callout MPSAFE.

- Expose acct_suspended via a read-only sysctl so it is possibly to
  programmatically determine whether accounting is suspended or not without
  attempting to parse logs.

- Check both acct_vp and acct_suspended lock-free before entering the
  accounting sx lock in acct().

- When accounting is disabled due to a VBAD vnode (i.e., forceable unmount),
  generate a log message indicating accounting has been disabled.

- Correct a long-standing bug in how free space is calculated and compared
  to the required space: generate and compare signed results, not unsigned
  results, or negative free space will cause accounting to not be suspended
  when required, or worse, incorrectly resumed once negative free space is
  reached.
