post collection. This is too error prone and introduces uncertainty into
the timing. We'll simply have to require synchronized TSCs to run
schedgraph on MP.

* Get the kernel module file name rather than hard-coding it like on Solaris.
* Use FreeBSD's process library API.
* Handle FreeBSD's different lock types.
* Get the list of loaded providers via a syscall.
* There are a few placeholders in here for which there isn't libproc
support code yet. This is relevent to userland tracing. This set of
commits is designed to get kernel tracing up and running, with the
userland stuff to follow later.
error is returned all the way back to the dtrace app, it's hard to
figure out where that error came from.
Add a couple of functions to get and set the error location which can
be optionally compiled into the library.
* Handle the different ioctl design.
* Support the freopen() changes.
* Use functions in FreeBSD's process library rather than the CDDL
library that Solaris has which sits on top of their process file
system and is therefore unsuitable for use on FreeBSD. The libproc
API for FreeBSD is deliberately different to that on Solaris because
Sun wouldn't release the libproc.h header under a BSD license.
* On FreeBSD define both LITTLE_ENDIAN and BIG_ENDIAN and then set the
BYTE_ORDER to the one we are using. On Solaris they define one or
the other but not both. For us to keep using FreeBSD header files,
we need to use endian definitions the same way we do in pure BSD
code.
use 'const' and just override it whenever we feel like it. If we use
it at all, then we need to do it properly.
Add a couple of functions that were useful in getting this code ported.
* Use the FreeBSD shell.
* On FreeBSD the tests run from the OBJDIR, so output files go there
rather than in the source tree like they do on Solaris.
* FreeBSD doesn't need a special path to the compiler.
OpenSolaris. This commit resets files to match the versions in the
OpenSolaris tree as of 2008/04/10.
The changes in this import from the previous import are the ones that
will subsequently re-applied to take files off the vendor branch. This
is unfortunately necessary because the Solaris developers won't allow
FreeBSD support #ifdefs in their source code because that creates
'dead code' (stuff that they never compile).
more wlans_<ifn> and create_args_<ifn>
Add documentation for these variants and generally update the wireless
device example.
There is are very short lived shim from vaps_<ifn> which produces
a warning and vap_create_<ifn> which does not. Misuse the MFC
notification service to remind me to remove them.

PR 122839 is fixed in both em and in igb
Second, the issue on building modules since the static kernel
build changes is now resolved. I was not able to get the fancier
directory hierarchy working, but this works, both em and igb
build as modules now.
Third, there is now support in em for two new NICs, Hartwell
(or 82574) is a low cost PCIE dual port adapter that has MSIX,
for this release it uses 3 vectors only, RX, TX, and LINK. In
the next release I will add a second TX and RX queue. Also, there
is support here for ICH10, the followon to ICH9. Both of these are
early releases, general availability will follow soon.
Fourth: On Hartwell and ICH10 we now have IEEE 1588 PTP support,
I have implemented this in a provisional way so that early adopters
may try and comment on the functionality. The IOCTL structure may
change. This feature is off by default, you need to edit the Makefile
and add the EM_TIMESYNC define to get the code.
Enjoy all!!
alowing the DDB output capture buffer to be easily extracted from
user space. Both of these commands include -M/-N arguments, allowing
them to be used with kernel crash dumps (or /dev/mem).
This makes it easier to use DDB scripting and output capture with
minidumps or full dumps rather than with text dumps, allowing DDB
output (scripted or otherwise) to be easily extracted from a crash
dump.

assumptions about the state of the cooling devices. Instead, switch them
off on init and, only after that, we are in TZ_ACTIVE_NONE.
