bhyve supports a single timer block with 8 timers. The timers are all 32-bit
and capable of being operated in periodic mode. All timers support interrupt
delivery using MSI. Timers 0 and 1 also support legacy interrupt routing.
At the moment the timers are not connected to any ioapic pins but that will
be addressed in a subsequent commit.
This change is based on a patch from Tycho Nightingale (tycho.nightingale@pluribusnetworks.com).

- A call was misplaced at the wrong level of nested if blocks, so that
the buffers for unix domain sockets (/dev/log, /dev/klog) were never
increased at all; they remained at a way-too-small default size of 4096.
- The function that was supposed to double the size of the buffer
sometimes did nothing, and sometimes installed a wildly-wrong buffer
size (either too large or too small) due to an unitialized 'slen'
variable passed to getsockopt(). Most often it doubled the UDP buffers
from 40k to 80k because accidentally there would be harmless stack
garbage in the unitialized variables.
- The whole concept of blindly doubling a socket's buffer size without
knowing what size it started at is a design flaw that has to be called a
bug. If the double_rbuf() function had worked at all (I.E., if the
other two bugs didn't exist) this would lead to UDP sockets having an
80k buffer while unix dgram sockets get an 8k buffer. There's nothing
about the problem being solved that requires larger buffers for UDP than
for unix dgram sockets -- the buffering requirements are the same
regardless of socket type.
This change renames the double_rbuf() function to increase_rbuf() and
increases the buffer size on all types of sockets to 80k. 80k was
chosen only because it appears to be the size the original change was
shooting for, and it certainly seems to be reasonably large (I might
have picked 64k in the absence of any historical guidance).

The effects of this patch would only be noticeable if you were purposefully

When bsdinstall(8) sources the bsdconfig(8) common.subr file,
PKG_ABI is set by calling 'pkg -vv' and searching for the ABI
pkg(8) will use.
When pkg(8) is run for the first time, the bootstrap process
is run, which prompts for 'y/N' input from stdin if running with
TERM set.
Since TERM is set and it is the first time pkg(8) is run, which
happens automatically, bsdinstall(8) hangs waiting for user input
which is never displayed since a specific line is expected by
awk(1), and stdin is expected by pkg(8).
Set ASSUME_ALWAYS_YES=1, which will cause pkg(8) to assume the
'-y' flag is also used for the bootstrap process, allowing
bsdinstall(8) to proceed to the keymap lookup, otherwise
bsdinstall(8) appears to hang after selecting 'Install' from the

+ Remove some unnecessary default ZFS datasets from the automatic "zfsboot"
script. Such as: /usr/ports/distfiles /usr/ports/packages /usr/obj /var/db
/var/empty /var/mail and /var/run (these can all be created as-needed once

+ Fix some i18n string violations in "zfsboot".
+ Bolster debugging output in "zfsboot".
+ Fix some string quoting issues in "zfsboot".
+ Fix some variable scope issues in "zfsboot".
+ Change "Create" to "Install" in "zfsboot" main menu.
+ Increase error checking in "zfsboot" (type-check arguments and such).
+ Add call to "graid destroy" killing automatic metadata (part of the series
of pedantic destructions we do when bootstrapping a new/naked disk).
+ Make judicious use of new f_eval_catch() in "zfsboot".
+ Fixup some variable names for consistency (zfsboot).
+ Fix an underride syntax parameter expansion folly (zfsboot).
+ Confirm layout if not explicitly chosen when blindly proceeding (no
longer have to touch anything on the ZFS menu if it scares you, just
choose the omnibus "Install" option at the top and you'll be prompted to
select vdev type and disks in the layout confirmation dialog).
+ Change numbered menu items to alphabetic for more efficient navigation.
+ Consolidate vdev selection and disk selection into a single stateful
menu which performs validation and allows backing out to each previous
menu as you go deeper.
+ Redesign the ``Last Chance'' dialog (still using the same colors, but
make it conform to a tolerable width and make disks appear in a block-
quote style indented region).
+ Fix a bug wherein we used the a lowercase variable name by accident
(actual variable name declared as all-uppercase) at the time of
initializing fstab(5) (not believed to cause any issues though).
+ Update the geli setup infobox for each provider being initialized
(not just at the onset -- since each ``geli init'' causes kernel messages
to push our infobox off-screen).

to a virtual machine then we implicitly create COM1 and COM2 ISA devices.
Prior to this change the only way of attaching a COM port to the virtual
machine was by presenting it as a PCI device that is mapped at the legacy
I/O address 0x3F8 or 0x2F8.
There were some issues with the original approach:
- It did not work at all with UEFI because UEFI will reprogram the PCI device
BARs and remap the COM1/COM2 ports at non-legacy addresses.
- OpenBSD GENERIC kernel does not create a /dev/console because it expects
the uart device at the legacy 0x3F8/0x2F8 address to be an ISA device.
- It was functional with a FreeBSD guest but caused the console to appear
on /dev/ttyu2 which was not intuitive.
The uart emulation is now independent of the bus on which it resides. Thus it
is possible to have uart devices on the PCI bus in addition to the legacy
COM1/COM2 devices behind the LPC bus.
The command line option to attach ISA COM1/COM2 ports to a virtual machine is
"-s <bus>,lpc -l com1,stdio".
The command line option to create a PCI-attached uart device is:
"-s <bus>,uart[,stdio]"
The command line option to create PCI-attached COM1/COM2 device is:
"-S <bus>,uart[,stdio]". This style of creating COM ports is deprecated.
