38f8fddf05 Add limited sandbox capability to "make check"
== 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.

a97fff1913 hyperv/hn: Fix/enhance receiving path when VF is activated.
- Update hn(4)'s stats properly for non-transparent mode VF.
- Allow BPF tapping to hn(4) for non-transparent mode VF.
- Don't setup mbuf hash, if 'options RSS' is set.
  In Azure, when VF is activated, TCP SYN and SYN|ACK go through hn(4)
  while the rest of segments and ACKs belonging to the same TCP 4-tuple
  go through the VF.  So don't setup mbuf hash, if a VF is activated
  and 'options RSS' is not enabled.  hn(4) and the VF may use neither
  the same RSS hash key nor the same RSS hash function, so the hash
  value for packets belonging to the same flow could be different!
- Disable LRO.
  hn(4) will only receive broadcast packets, multicast packets, TCP
  SYN and SYN|ACK (in Azure), LRO is useless for these packet types.
  For non-transparent, we definitely _cannot_ enable LRO at all, since
  the LRO flush will use hn(4) as the receiving interface; i.e.
  hn_ifp->if_input(hn_ifp, m).

While I'm here, remove unapplied comment and minor style change.

a6e709f29c Add hinted attachment for non-FDT systems. Also, print a message if
setting up the timer fails, because on some types of chips that's the
first attempt to access the device.  If the chip is missing/non-responsive
then you'd get a driver that attached and didn't register the rtc, with
no clue about why.  On other chip types there are inits that come before
timer setup, and they already print messages about errors.

bb2e8108e1 Add a new driver, ds13rtc, that handles all DS13xx series i2c RTC chips.
This driver supports only basic timekeeping functionality.  It completely
replaces the ds133x driver.  It can also replace the ds1374 driver, but that
will take a few other changes in MIPS code and config, and will be committed
separately.  It does NOT replace the existing ds1307 driver, which provides
access to some of the extended features on the 1307 chip, such as controlling
the square wave output signal.  If both ds1307 and ds13rtc drivers are
present, the ds1307 driver will outbid and win control of the device.

This driver can be configured with FDT data, or by using hints on non-FDT
systems.  In addition to the standard hints for i2c devices, it requires
a "chiptype" string of the form "dallas,ds13xx" where 'xx' is the chip id
(i.e., the same format as FDT compat strings).

make gicv3_get_nirqs return the number of available interrupt IDs, and

2db14f97de Add config_intrhook_oneshot(): schedule an intrhook function and unregister
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.

037331ddbd When read requests are sent from a filesystem running above g_journal,
the g_journal level needs to check whether it is holding a newer
copy of the block than that which exists on the disk. If so, it
needs to return its copy. If not, it should pass the request down
to the disk to fulfill. It currently considers six queues:

0) delayed queue,
1) unsent (current queue),
2) in-flight to the journal (flush queue),
3) active journal (active queue),
4) inactive journal (inactive queue), and
5) inflight to the disk (copy queue).

Checking on two of these queues is unnecessary:

0) The delayed requests should not be used for reads because they
   have not yet been entered into the journal, so their value should
   reflect the disk contents, not the future contents that are not
   yet committed.

2) Because all the bio's in the flush queue are also found on the
   active queue, there is no need to inspect the flush queue for
   reads since they will be found when searching the active queue.

bee93d3cf0 The *_meta_* functions include a radix parameter, a blk parameter, and
another parameter that identifies a starting point in the memory address
block.  Radix is a power of two, blk is a multiple of radix, and the
starting point is in the range [blk, blk+radix), so that blk can always be
computed from the other two.  This change drops the blk parameter from the
meta functions and computes it instead.  (On amd64, for example, this
change reduces subr_blist.o's text size by 7%.)

It also makes the radix parameters unsigned to address concerns that the
calculation of '-radix' might overflow without the -fwrapv option.  (See

992029ba10 Reliably enable debug exceptions on all CPUs.
Previously, debug exceptions were only enabled on the boot CPU if
DDB was enabled in the dbg_monitor_init() function.  APs also called
this function, but since mp_machdep.c doesn't include opt_ddb.h, the
APs ended up calling an empty stub defined in <machine/debug_monitor.h>
instead of the real function.  Also, if DDB was not enabled in the kernel,
the boot CPU would not enable debug exceptions.

Fix this by adding a new dbg_init() function that always clears the OS
lock to enable debug exceptions which the boot CPU and the APs call.
This function also calls dbg_monitor_init() to enable hardware breakpoints
from DDB on all CPUs if DDB is enabled.  Eventually base support for
hardware breakpoints/watchpoints will need to move out of the DDB-only
debug_monitor.c for use by userland debuggers.
