44653522f6 Add a way to apply CFLAGS only when building the given architecture. This
is useful primarily on a system used for cross-building, when you have a
set of flags to apply to the TARGET_ARCH being cross-built but don't want
those settings applied to building the cross-tools or other components that
run on the build host machine.

9b84048643 Remove unnecessary svn:executable property from source file.
The atf cp_test.sh sample file should have never been marked executable in
the first place because this file needs to be "built" first before being

f5fd950e35 Make bsd.test.mk the only public mk fragment for the building of tests.
Change {atf,plain,tap}.test.mk to be internal implementation details of
bsd.test.mk.  Makefiles that build tests should now only include bsd.test.mk
and declaratively specify what they want to build, without worrying about
the internal implementation of the mk files.

The reason for this change is to permit building test programs of different
interfaces from a single directory, which is something I had a need for
while porting tests over from src/tools/regression/.

Additionally, this change makes it possible to perform some other requested
changes to bsd.test.mk in an easier manner.  Coming soon.

9e684a3a79 Generate plain sh test programs from a source file.
Instead of assuming that plain sh test programs exist in the source
tree in their final form and are marked as executable, generate them
from a list of sources.

By default, just assume that the source file for a program P is P.sh
but allow the caller to customize the inputs.  Similarly, also allow
the caller to apply sed(1) replacements on the output.  These will
both be useful in hooking existing test code from tools/regression/
into the test suite.

21203fdd06 Add some sample test programs.
This change adds some sample test cases to share/examples/tests/
demonstrating the basic usage of the atf and plain interfaces.

These test programs are fully-functional and are installed as part
of the test suite, which guarantees that the sample code remains
correct.  However, they currently mostly serve as a placeholder for
additional examples and may be incomplete (depending on how you
look at them).  I will see what else can be useful while working on
documentation.

As a bonus, the addition of these tests exercise the *.test.mk files,
one of which (plain.test.mk) was not yet in use, and also demonstrates
that it's possible to mix different kinds of test programs into the
same test suite.

ea7f1c8cd2 Add support for PCI-to-ISA LPC bridge emulation. If the LPC bus is attached
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.

cc4d059c03 Merge from project branch. Uninteresting commits are trimmed.
Refactor of /dev/random device. Main points include:

* Userland seeding is no longer used. This auto-seeds at boot time
on PC/Desktop setups; this may need some tweeking and intelligence
from those folks setting up embedded boxes, but the work is believed
to be minimal.

* An entropy cache is written to /entropy (even during installation)
and the kernel uses this at next boot.

* An entropy file written to /boot/entropy can be loaded by loader(8)

* Hardware sources such as rdrand are fed into Yarrow, and are no
longer available raw.

Debugging. My attempt at EVENTHANDLER(multiuser) was a failure; use
EVENTHANDLER(mountroot) instead.

This means we can't count on /var being present, so something will
need to be done about harvesting /var/db/entropy/... .

Some policy now needs to be sorted out, and a pre-sync cache needs
to be written, but apart from that we are now ready to go.

Over to review.

Looking pretty good; this mostly works now. New code includes:

Simplify the harvest queue.

Marginally improve the entropy pool hashing, making it a bit faster

* Remove 'frac' parameter from random_harvest(). This was never
used and adds extra code for no good reason.

* Remove device write entropy harvesting. This provided a weak
attack vector, was not very good at bootstrapping the device. To
follow will be a replacement explicit reseed knob.

* Separate out all the RANDOM_PURE sources into separate harvest
entities. This adds some secuity in the case where more than one
is present.

* Review all the code and fix anything obviously messy or inconsistent.

fdcb645387 Fix examples for overriding INSTALL to not suggest hardcoding
'install' since it breaks buildworld after the introduction and
use of 'install -l' in r245752. Overriding INSTALL causes
/usr/bin/install to be used instead of the proper
/usr/src/tools/install.sh which handles the new flag.

08e90c1491 Tidy up bsd.cpu.mk for X86 CPUs:
- Do not limit recent processors to "prescott" class for i386 target.  There
is no reason for this hack because clang is default now.  On top of that, it
will only grow indefinitely over time.
- Add more CPUTYPEs, i.e., "athlon-fx", "core-avx2", "atom", "penryn", and
"yonah".  Note "penryn" and "yonah" are intentionally undocumented because
they are not supported by gcc and marked deprecated by clang.
- Add more CPUTYPE aliases, i.e., "barcelona" (-> amdfam10), "westmere" and
"nehalem" (-> corei7).  Note these are intentionally undocumented because
they are not supported by (base) gcc and/or clang.  However, LLVM (backend)
seems to "know" the differences.  Most likely, they were deprecated with
other vendor code names and clang did not bother implementing them at all.
- Add i686 to MACHINE_CPU for "c3-2" (VIA Nehemiah).  Both gcc & clang treat
it like an i686-class processor.
- Add IDT "winchip2" and "winchip-c6" for completeness (undocumented).
- Order processors per make.conf example, i.e., CPU vendors and models.
- Tidy up make.conf example, i.e., remove "by gcc" (because we have aliases)
and remove "prescott" from AMD64 architecture (because it is not correct).

04704c638e Remove fictitious support for 80386-class CPUs from bsd.cpu.mk and make(1).
It was removed from head more than 8 years ago (see r137784 and r137785).
