A later change, currently being iterated on in D24459, will in-fact change
the lock type to an sx so that TTY drivers can sleep on it if they need to.
Committing this ahead of time to make the review in question a little more
palatable.
tty_lock_assert() is unfortunately still needed for now in two places to
make sure that the tty lock has not been recursed upon, for those scenarios
where it's supplied by the TTY driver and possibly a mutex that is allowed
to recurse.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

acquiring the tty lock in bvm_tty_close(). Instead just assert that the tty
lock is held before calling callout_reset().

- Set the console name always so that the bvm console device can be used
via conscontrol even if it isn't chosen as the default console.

run as a 1/2 CPU guest on an 8.1 bhyve host.
bhyve/inout.c
inout.h
fbsdrun.c
- Rather than exiting on accesses to unhandled i/o ports, emulate
hardware by returning -1 on reads and ignoring writes to unhandled
ports. Support the previous mode by allowing a 'strict' parameter
to be set from the command line.
The 8.1 guest kernel was vastly cut down from GENERIC and had no
ISA devices. Booting GENERIC exposes a massive amount of random
touching of i/o ports (hello syscons/vga/atkbdc).
bhyve/consport.c
dev/bvm/bvm_console.c
- implement a simplistic signature for the bvm console by returning
'bv' for an inw on the port. Also, set the priority of the console
to CN_REMOTE if the signature was returned. This works better in
an environment where multiple consoles are in the kernel (hello syscons)
bhyve/rtc.c
- return 0 for the access to RTC_EQUIPMENT (yes, you syscons)
amd64/vmm/x86.c
x86.h
- hide a bunch more CPUID leaf 1 bits from the guest to prevent
cpufreq drivers from probing.
The next step will be to move CPUID handling completely into
user-space. This will allow the full spectrum of changes from
presenting a lowest-common-denominator CPU type/feature set, to
exposing (almost) everything that the host can support.

This branch is now considered frozen: future bhyve development will take
place in a branch off -CURRENT.
sys/dev/bvm/bvm_console.c
sys/dev/bvm/bvm_dbg.c
- simple console driver/gdb debug port used for bringup. supported
by user-space bhyve executable
sys/conf/options.amd64
sys/amd64/amd64/minidump_machdep.c
- allow NKPT to be set in the kernel config file
sys/amd64/conf/GENERIC
- mptable config options; bhyve user-space executable creates an mptable
with number of CPUs, and optional vendor extension
- add bvm console/debug
- set NKPT to 512 to allow loading of large RAM disks from the loader
- include kdb/gdb
sys/amd64/amd64/local_apic.c
sys/amd64/amd64/apic_vector.S
sys/amd64/include/specialreg.h
- if x2apic mode available, use MSRs to access the local APIC, otherwise
fall back to 'classic' MMIO mode
sys/amd64/amd64/mp_machdep.c
- support AP spinup on CPU models that don't have real-mode support by
overwriting the real-mode page with a message that supplies the bhyve
user-space executable with enough information to start the AP directly
in 64-bit mode.
sys/amd64/amd64/vm_machdep.c
- insert pause statements into cpu shutdown busy-wait loops
sys/dev/blackhole/blackhole.c
sys/modules/blackhole/Makefile
- boot-time loadable module that claims all PCI bus/slot/funcs specified
in an env var that are to be used for PCI passthrough
sys/amd64/amd64/intr_machdep.c
- allow round-robin assignment of device interrupts to CPUs to be disabled
from the loader
sys/amd64/include/bus.h
- convert string ins/outs instructions to loops of individual in/out since
bhyve doesn't support these yet
sys/kern/subr_bus.c
- if the device was no created with a fixed devclass, then remove it's
association with the devclass it was associated with during probe.
Otherwise, new drivers do not get a chance to probe/attach since the
device will stay married to the first driver that it probed successfully
but failed to attach.
