Add deprecation notice for bvmconsole and bvmdebug.
Now that bhyve(8) supports UART, bvmconsole and bvmdebug are no longer needed.
Mark the '-b' and '-g' flag as deprecated for bhyve(8).
These will be removed/gone in 13.
MFC r360051: tty: convert tty_lock_assert to tty_assert_locked2020-04-24T13:31:22ZKyle Evanskevans@FreeBSD.org2020-04-24T13:31:22Zurn:sha1:74727284b626971c5209f162f593ec65d4606b64
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.
sys/dev: further adoption of SPDX licensing ID tags.2017-11-27T14:52:40ZPedro F. Giffunipfg@FreeBSD.org2017-11-27T14:52:40Zurn:sha1:718cf2ccb9956613756ab15d7a0e28f2c8e91cab
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.

Changes to allow the GENERIC+bhye kernel built from this branch to2011-05-19T21:53:25ZPeter Grehangrehan@FreeBSD.org2011-05-19T21:53:25Zurn:sha1:1f3025e13378bfb7be746e15743c2050fae45a93
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.
