describes the minimum versions of each feature and each chipset type
supported by this driver. Basically, unless you have a very modern
version of firmware on a Prism card, you won't be able to use these
cards for much on modern networks that have any kind of protection
enabled, except for the few WEP-only stranglers that appear at some
conferences...
This gives significant performance improvements when many raw sockets used.
Benchmarks of mpd handeling 1000 simultaneous PPTP connections show up to 50%
performance boost. With higher number of connections benefit becomes even
bigger. PopTop snd others should also get some benefits.
the beginning. There's a race in the shared interrutp case. If
another interrupt happens after the interrupt is setup, then we'd try
to lock an uninitialized mutex. In addition, if we bailed out due to
a too old version of firmware, we'd leave the interrupt enabled with
all the fun that ensues....

Yes, it means some old bugs returned, like not setted rs_stired = 1 in
arc4random_stir(3) causing double stirring.
The ttyinfo() routine generates the fancy output when pressing ^T. Right
now it is stored in tty.c. In the MPSAFE TTY code it is already stored
in tty_info.c. To make integration of the MPSAFE TTY code a little
easier, take the same approach.
This makes the TTY code a little bit more readable, because having the
proc_*/thread_* routines in tty.c is very distractful.

When I turned sgtty into a binary-only interface (last month), I added
this explicit #error to the header file, to make sure nobody forgot to
remove the header file after updating world.
I think it is now a good moment to remove this header file.

The kbd, kbdmux, ugen and uhid drivers included <sys/tty.h>, because
they needed clists, which have been moved to <sys/clist.h> some time
ago. In the MPSAFE TTY branch, <sys/tty.h> does not include
<sys/clist.h>, which means we have to teach these drivers to include
this header file directly.

We're very lucky, because the flags used by our TIOCPKT implementation
are the same as flags used by Linux. We can safely enable TIOCPKT,
assuming EXTPROC is not used.
TIOCSPTLCK is used by unlockpt(). Because we don't need unlockpt() in
our implementation, make this ioctl a no-op.

but removed too much, breaking the build in other places instead. Now
that the ipfilter issue has been fixed (or hacked around), address the
second issue by restoring r180755, with one small change. I don't feel
comfortable using assert(3) in a header that will be included in userland
code that may or may not already have an assertion mechanism in place,
so KASSERT() evaluates to a no-op in the !_KERNEL case.
own purposes. To pull this off, it defines _KERNEL before including the
headers where these structures are defined. This leads to no end of
trouble when some of these headers, or other headers that they include,
change, as demonstrated by r180755.
The quick fix in this particular case is to define _WANT_FILE instead of
_KERNEL, conditional on __FreeBSD__. A better long-term fix is left as
an exercise to the reader.
behavior. Specifically, probe Host-PCI bridges in the order they are
encountered in the tree. For CPUs, just use an order of 100000 and assume
that no Host-PCI bridges will be more than 10000 levels deep in the
namespace. This fixes an issue on some boxes where the HPET timer stopped
attaching.
vnode buffers locked at once. In particular, there are indirect buffers
among locked ones. The bdwrite() may start the flushing to keep dirty
buffer list at the bounds. If any buffer on the dirty list requires
translation from logical to physical block number, code may ends up
trying to lock an indirect buffer already locked in ffs_balloc_ufsX.
Prevent the bdflush() activity when several buffers are locked at once
by setting the TDP_INBDFUSH for the problematic code blocks.

when stack realignment is turned on (it is ALWAYS on for main), however
in a profiling build %ecx would be clobbered by mcount(), this would lead
to a segmentation fault when the code tries to reference any argument.
This fix changes mcount() to preserve %ecx.

return NDIS_STATUS_PENDING. In this case, it's waiting for 5 secs to
get the response from drivers now. However, some NDIS drivers can send
the response before NDIS framework gets ready to receive it so we might
always be blocked for 5 secs in current implementation. NDIS framework
should reset the event before calling NDIS driver's callback not after.

This commit will,

device and the MSI address matches the HT mapping window.
2. enable MSI mapping on a bridge only when a downstream device is
allocated an MSI address in the mapping window
