This driver supports both NTB-to-NTB and NTB-to-Root Port modes (though
the second with predictable complications on hot-plug and reboot events).
I tested it with PEX 8717 and PEX 8733 chips, but expect it should work
with many other compatible ones too. It supports up to two NT bridges
per chip, each of which can have up to 2 64-bit or 4 32-bit memory windows,
6 or 12 scratchpad registers and 16 doorbells. There are also 4 DMA engines
in those chips, but they are not yet supported.
While there, rename Intel NTB driver from generic ntb_hw(4) to more specific
ntb_hw_intel(4), so now it is on par with this new ntb_hw_plx(4) driver and
alike to Linux naming.

Also disable this if NO_SAFE_LIBINSTALL is defined.
There is little harm in always using -S and it fixes several issues:
- A race during 'make libraries' where, for example, libgcc_s is being
installed while another library is trying to link against it. This is
possible because libgcc_s is connected in both _prereq_libs and
_startup_libs. The first build (_prereq_libs) sets MK_PROFILE=no
while the 2nd pass (_startup_libs) enables MK_PROFILE. Thus the
libgcc_s library *is* present in WORLDTMP for other libraries to
link to, so serializing further items in _startup_libs is not
required. Just ensuring that libgcc_s is installed atomically (via
rename(2)) is enough. [1]
- Installation to a running system where some library that cannot be
detected, copied and used from the temporary INSTALLTMP with LD_LIBRARY_PATH
that the build itself uses for installation. Such an example is having the
install an NSS module for user lookups that install(1) uses while
concurrently installing the module in another process. This is not
a problem for the FreeBSD base build but can be for downstream
vendors. While this is a very specific case, installation to a
running system with non-atomic library installation is prone to many
problems. A further step still is to install in proper dependency
ordering.

== Rationale ==
r295380 introduced "make check" and consolidated means for running
test code in an attempt to simplify running tests. One could either
install files/libraries/programs and run "make check", or run "make check"
with an explicit CHECKDIR, e.g., `make check CHECKDIR=$(make -V.OBJDIR)``.
One criticism that was received is that "make check" should be run with
the intent of making dev->test->commit easier, which means that the target
audience's workflow should be developers. One developer pattern available
in other opensource projects is to run test code from a developer sandbox,
instead of installing to a system.
== Method ==
This approach is slightly different from the standard approach, in the sense
that it builds and installs into a deterministic directory under .OBJDIR (as I call it,
the "sandbox"), then runs "make check" against that. In the event the test
run is successful, the deterministic directory is removed to save space.
== Approach ==
bsd.lib.mk, bsd.prog.mk:
To support this functionality, a new variable `HAS_TESTS` is being added.
HAS_TESTS enables appropriate behavior with bsd.lib.mk and bsd.prog.mk, as
follows:
- Add "make check" as an available target from the directory.
- Pass down appropriate variables via ${TESTS_ENV}, i.e.,
${TESTS_LD_LIBRARY_PATH} and ${TESTS_PATH}.
One should add "HAS_TESTS" to directories containing tests in them, e.g. from
bin/sh/Makefile,
HAS_TESTS=
SUBDIR.${MK_TESTS}+= tests
HAS_TESTS doesn't automatically add the tests subdirectory for flexibility
reasons.
bsd.opts.mk, src.opts.mk:
- The knob ${MK_MAKE_CHECK_USE_SANDBOX} has been added, both to explicitly
direct (internally) when to set a deterministic ${DESTDIR} and to also allow
users to disable this behavior globally, i.e., via src.conf.
- MK_TESTS has been promoted from src.opts.mk to bsd.opts.mk to leverage
syntactic sugar for having MK_TESTS be a dependency for
MK_MAKE_CHECK_USE_SANDBOX, but to also ensure that src.opts.mk isn't required
to use suite.test.mk (which is a dependency of bsd.test.mk).
suite.test.mk:
- beforecheck behavior (when MK_MAKE_CHECK_USE_SANDBOX is enabled) is modified
from a no-op to:
-- Build.
-- Run "make hierarchy" on the sandbox dir.
-- Install the tests/files to the sandbox dir.
- aftercheck behavior (when MK_MAKE_CHECK_USE_SANDBOX is enabled) is modified
from a no-op to:
-- Remove the sandbox dir.
Again, because the dependency order set in bsd.test.mk is
beforecheck -> check -> aftercheck, "make check" will not be run unless
"beforecheck" completes successfully, and "aftercheck" will not be run unless
"beforecheck" and "check" complete successfully.
== Caveats ==
- This target must either be run with MK_INSTALL_AS_USER or as root. Otherwise
it will fail when running "make install" as the default user/group for many
makefiles when calling INSTALL is root/wheel.
- This target must be run from a suitable top-level directory. For example,
running tests from `tests/sys/fs/tmpfs` won't work, but `tests/sys/fs` will,
because `tests/sys/fs/tmpfs` relies on files installed by `tests/sys/fs`.
- Running MK_INSTALL_AS_USER may introduce determinism issues. However, using
it could identify deficiences in tests in terms of needing to be run as
root, which are not properly articulated in the test requirements.
- The doesn't negate the need for running "make installworld" and
"make checkworld", etc. Again, this just is intended to simplify the
dev->test->commit workflow.
== Cleanup done ==
- CHECKDIR is removed; one can use "MK_MAKE_CHECK_USE_SANDBOX=no" to enable
"legacy" (r295380) behavior.

it automatically after it runs.
The config_intrhook mechanism allows a driver to stall the boot process
until device(s) required for booting are available, by not allowing system
inits to proceed until all intrhook functions have been unregistered.
Virtually all existing code simply unregisters from within the hook function
when it gets called.
This new function makes that common usage more convenient. Instead of
allocating and filling in a struct, passing it to a function that might (in
theory) fail, and checking the return code, now a driver can simply call
this cannot-fail routine, passing just the intrhook function and its arg.

Implement disk_add_alias to allow aliases to be added to disks. All
disk have a primary name (say "foo") can also have secondary names
(say "bar") such that all instances of "foo" also have a "bar"
alias. So if you have foo0, foo0p1, foo1, foo1s1 and foo1s1a nodes
created by the foo driver and gpart, device nodes bar0, bar0p1, bar1,
bar1s1 and bar1s1a will appear as symlinks back to the original nodes.
This generalizes to multiple aliases. However, since the unit number
follows the primary name, multiple device drivers can't create the
same aliases unless those drives coorinate the unit number space (eg
you couldn't add an alias 'disk' to both 'da' and 'ada' because it's
possible to have da0 and ada0, because 'disk0' is ambiguous).

This removes a need for passing CLEANDIRS in to "make clean" in a slightly
convoluted way.
Also, remove the ${MAKE_CHECK_SANDBOX_DIR} is already present -> bail logic.
It was incredibly annoying dealing with false positives/failures (of which
there are a handful in the tree with tests). It's better to just assume that
the user is smart enough to do the right thing and not invoke "make check"
(sandboxed) multiple times, keeping ${MAKE_CHECK_SANDBOX_DIR}.
