63e6f39011 When using m_dup(9) to copy more than MHLEN bytes of data, don't create an
mbuf chain that starts with a cluster containing just MHLEN bytes.  This
happened because m_dup called m_get or m_getcl depending on the amount of
data to copy, but then always set the size available in the first mbuf to
MHLEN.

5351742ea2 Mega update to the LSI MegaRAID driver:
1.  Implement a large set of ioctl shims so that the Linux management apps
from LSI will work.  This includes infrastructure to support adding, deleting
and rescanning arrays at runtime.  This is based on work from Doug Ambrosko,
heavily augmented by LSI and Yahoo.

2.  Implement full 64-bit DMA support.  Systems with more than 4GB of RAM
can now operate without the cost of bounce buffers.  Cards that cannot do
64-bit DMA will automatically revert to using bounce buffers.  This option
can be forced off by setting the 'hw.amr.force_sg32" tunable in the loader.
It should only be turned off for debugging purposes.  This work was sponsored
by Yahoo.

3.  Streamline the command delivery and interrupt handler paths after
much discussion with Dell and LSI.  The logic now closely matches the
intended design, making it both more robust and much faster.  Certain
i/o failures under heavy load should be fixed with this.

4.  Optimize the locking.  In the interrupt handler, the card can be checked
for completed commands without any locks held, due to the handler being
implicitely serialized and there being no need to look at any shared data.
Only grab the lock to return the command structure to the free pool.  A
small optimization can still be made to collect all of the completions
together and then free them together under a single lock.

Items 3 and 4 significantly increase the performance of the driver.  On an
LSI 320-2X card, transactions per second went from 13,000 to 31,000 in my
testing with these changes.  However, these changes are still fairly
experimental and shouldn't be merged to 6.x until there is more testing.

Thanks to Doug Ambrosko, LSI, Dell, and Yahoo for contributing towards
this.

6239708b1c Fix the Tigon I/II driver to support 64-bit DMA. In the process, convert it
to use busdma.  Unlike most of the other drivers, but similar to the
if_em driver, pre-allocate the dmamaps at init time instead of allocating
them on the fly when descriptors need to be filled.  This isn't ideal right
now because a map is allocated for every descriptor slot in the tx, rx, mini,
and jumbo rings (which is a lot!) in order to simplify the bookkeeping, even
though the driver might support filling only a subset of those slots.
Luckily, maps are typically NULL on i386 and amd64, so the cost isn't
very high.  It could be an issue with sparc64, but the driver isn't endian
clean either, and that is a much bigger problem to solve first.

Note that jumbo frame support is under-tested, and I'm not even sure if
it till really works correctly given the evil VM magic that is does.
The changes here attempt to preserve the existing semanitcs.

Thanks to Martin Nillson for contributing the Netgear card for this work.

d272fe53a4 Add a new 'show lock' command to ddb. If the argument has a valid lock
class, then it displays various information about the lock and calls a
new function pointer in lock_class (lc_ddb_show) to dump class-specific
information about the lock as well (such as the owner of a mutex or
xlock'ed sx lock).  This is easier than staring at hex dumps of locks to
figure out who owns the lock, etc.  Note that extending lock_class doesn't
affect the ABI for any kernel modules as the only code that deals with
lock_class structures directly is kern_mutex.c, kern_sx.c, and witness.

ec761d7501 Optimize by not doing excessive conversions for handling the sign bit.
This gives an optimization of between 9 and 22% on Athlons (largest
for cbrt() on amd64 -- from 205 to 159 cycles).

We extracted the sign bit and worked with |x|, and restored the sign
bit as the last step.  We avoided branches to a fault by using accesses
to FP values as bits to clear and restore the sign bit.  Avoiding
branches is usually good, but the bit access macros are not so good
(especially for setting FP values), and here they always caused pipeline
stalls on Athlons.  Even using branches would be faster except on args
that give perfect branch misprediction, since only mispredicted branches
cause stalls, but it possible to avoid touching the sign bit in FP
values at all (except to preserve it in conversions from bits to FP
not related to the sign bit).  Do this.  The results are identical
except in 2 of the 3 unsupported rounding modes, since all the
approximations use odd rational functions so they work right on strictly
negative values, and the special case of -0 doesn't use an approximation.

15b7edbeaa Don't check the CPUID_APIC bit in the cpu_features flags field to determine
if the boot CPU has a local APIC because some BIOS vendors are not
competent enough to set this bit.  Instead, just assume that we always have
a local APIC on amd64.  For i386 the check is a bit more subtle.  FreeBSD
requires either an MP Table or an ACPI MADT table to enumerate APICs.  The
only systems that have one of those tables that don't have local APICs are
some presumably rare (and old) SMP 486 systems using external APICs.  Thus,
instead of checking the CPUID_APIC flag, check the CPU class and abort if
we are running on a 486.

b384108ed6 /* You're not supposed to hit this problem */
For some denormalized long double values, a bug in __hldtoa() (called
from *printf()'s %A format) results in a base 16 digit being rounded
up from 0xf to 0x10.

When this digit is subsequently converted to string format, an index
of 10 reaches past the end of the uppper-case hex/char array, picking
up whatever the code segment happen to contain at that address.

This mostly seem to be some character from the upper half of the
byte range.

When using the %a format instead of %A, the first character past
the end of the lowercase hex/char table happens to be index 0 in
the uppercase hex/char table hextable and therefore the string
representation features a '0', which is supposedly correct.

This leads me to belive that the proper fix _may_ be as simple as
masking all but the lower four bits off after incrementing a hex-digit
in libc/gdtoa/_hdtoa.c:roundup().  I worry however that the upper
bit in 0x10 indicates a carry not carried.

Until das@ or bde@ finds time to visit this issue, extend the
hexdigit arrays with a 17th index containing '?' so that we get a
invalid but consistent and printable output in both %a and %A formats
whenever this bug strikes.

This unmasks the bug in the %a format therefore solving the real
issue may both become easier and more urgent.

40b1ae9e00 Add a new feature for optimizining ipfw rulesets - substitution of the
action argument with the value obtained from table lookup. The feature
is now applicable only to "pipe", "queue", "divert", "tee", "netgraph"
and "ngtee" rules.

An example usage:

  ipfw pipe 1000 config bw 1000Kbyte/s
  ipfw pipe 4000 config bw 4000Kbyte/s
  ipfw table 1 add x.x.x.x 1000
  ipfw table 1 add x.x.x.y 4000
  ipfw pipe tablearg ip from table(1) to any

In the example above the rule will throw different packets to different pipes.

TODO:
  - Support "skipto" action, but without searching all rules.
  - Improve parser, so that it warns about bad rules. These are:
    - "tablearg" argument to action, but no "table" in the rule. All
      traffic will be blocked.
    - "tablearg" argument to action, but "table" searches for entry with
      a specific value. All traffic will be blocked.
    - "tablearg" argument to action, and two "table" looks - for src and
      for dst. The last lookup will match.

6bcdd71391 For the amd64 platform, we can depend on the TSC being present. This patch
changes DELAY to use the TSC once it has been calibrated.  This does NOT
use the TSC for long-term timekeeping.   It only uses it to bound the
DELAY() spinloop.  This should not be affected by the Athlon64 X2 TSC
quirks because the cpu is not halted while we use DELAY().
