Instead of returning 0xffs some controllers, such as Layerscape generate
an external exception when someone attempts to read any register
of config space of a non-existing device other than PCIR_VENDOR.
This causes a kernel panic.
Fix it by bailing during device enumeration if a device vendor register
returns invalid value. (0xffff)
Use this opportunity to replace some hardcoded values with a macro.
I believe that this change won't have any unintended side-effects since
it is safe to assume that vendor == 0xffff -> hdr_type == 0xffff.

So, if we're processing a timeout, and we've sent an ABORT to the
firmware for that timeout, but not yet received the response from the
firmware, AND we get another timeout, we queue the timeout and freeze
the queue. However, when we've finally processed them all, we only
release the queue once. This causes all I/O to halt as the devq remains
frozen forever.
Instead, only freeze the queue when we start the process (eg set INRESET
on the target). This will allow the release when all the timed out I/Os
have finished ABORTing.

frequency = base clock / (prescaler * divisor), where prescaler can be

386BSD provided a MD function sysbeep. This took two arguments (pitch
and period). Pitch was jammed into the PIT's divisor directly (which
means the argument was expected to sound a tone at '1193182 / pitch'
Hz). FreeBSD inherited this interface.
In commit e465985885 (svn 177642, Mar 26 2008), phk changed this
function to take a tone to sound in hz. He converted all in-tree
instances of 1193182 / hz to just hz (and kept the few misguided folks
that passed hz directly unchanged -- this was part of what motivated the
change). He converted the places where we pre-computed the 8254 divisor
from being pitch to 1193182 / pitch (since that converts the divisor to
the frequency and the interfaces that were exposed to userland exposed
it in these units in places, continuing the tradition inherited from SCO
System V/386 Unix in spots).
In 2009, Ed Shouten was contracted by the FreeBSD Foundation to write /
finish newcons. This work was done in perforce and was imported into
subversion in user/ed/newcons in revision 199072
(https://svnweb.freebsd.org/base?view=revision&revision=199072) which
was later imported into FreeBSD by ray@ (Aleksandr Rybalko).
From that earliest import into svn import to this date, we ring the bell
with:
sysbeep(1193182 / VT_BELLPITCH, VT_BELLDURATION);
where VT_BELLPITCH was defined to be 800. This results in a bell
frequency of 1491Hz, more or less today. This is similar to the
frequency that syscons and pcvt used (1493Hz and 1500Hz respectively).
This in turn was inherited from 386BSD, it seems, which used the hard
coded value 0x31b which is 795 -> 1500Hz.
This '800' was intended to be the bell tone (eg 800Hz) and this
interface was one that wasn't converted. The most common terminal prior
to the rise of PCs was the VT100, which had an approximately 800Hz
bell. Ed Shouten has confirmed that the original intent was 800Hz and
changing this was overlooked after the change to -current was made.
This restors that original intent and makes the bell less obnoxious in
the process.

kbdcontrol also parses 'off' but then doesn't send the proper escape
