contrib/netbsd-tests
This Makefile snippet handles polluting testcases with -lnetbsd, specific
headers for ATF version differences, and does necessary rewriting for the
testcases to match the format discussed on the TestSuite wiki page
(t_<foo> -> <foo>_test)
One must define SRCTOP (inspired by projects/bmake), OBJTOP, and TESTSRC
(e.g. contrib/netbsd-tests/lib/libc/gen) to use the Makefile snippet
Test programs are specific either via NETBSD_ATF_TESTS_C or NETBSD_ATF_TESTS_SH
C++ analogs aren't currently implemented.
The imported testcases will be cleaned up to use this Makefile snippet pseudo
"API".
In most cases, the buffers and data were resized, but when dealing with the
helpers, some of the code was adjusted to fail more reliably

- The blocksize on FreeBSD is 32kB, not 64kB
- Add some detection for MK_DICT == no; /nonexistent is echoed along with
atf_skip to ensure that the test will fail if dict(..) is called in the
non-final stage of the pipeline

Those tunables are used to set a specific mode in vt(4) instead of using
the default mode.

... and their associated tunables. This gives a way to know the list of
available connectors, no matter the driver.
The problem is that xrandr(1) can list connectors but it uses a
different naming.

Impact on capability races was small: it was possible to get a spurious
ENOTCAPABLE (early return), but it was not possible to bypass checks.
Tidy up some comments.
875. This intersects with the agp_i810.c, which supports all Intels
from i810 to Core i5/7. Both agp_intel.c and agp_i810.c are compiled
into kernel when device agp is specified in config, and agp_i810
attach seems to be selected by chance due to linking order.
Strip support for 810 and later from agp_intel.c. Since 440-class
chipsets do not support any long-mode capable CPUs, remove agp_intel.c
from amd64 kernel file list. Note that agp_intel.c is not compiled
into agp.ko on amd64 already.

By default, vt(4) gets the "preferred mode" from DRM, when using a DRM
video driver as its backend. The preferred mode is usually the native
screen resolution.
Now, if this mode isn't appropriate, a user can use loader tunables to
select a mode. The tunables are read in the following order:
1. kern.vt.fb.modes.$connector_name
2. kern.vt.fb.default_mode
For example, to set a 1024x768 mode, no matter the connector:
kern.vt.fb.default_mode="1024x768"
To set a 800x600 mode only on the laptop builtin screen:
kern.vt.fb.modes.LVDS-1="800x600"

This causes the directory traversing Kyuafile to be installed, which in turn
causes tests/sys/pjdfstest to always be run from /usr/tests/sys
Let KYUAFILE default to auto, so the file generated by suite.test.mk gets
installed instead

pjdfstest execution is opt-in and must be done as root due to some of the
assumptions made by the test suite and lack of error checking in the non-root
case

Currently sizeof(struct filedesc0) is 1096 bytes, which means allocations from
malloc use 2048 bytes.
There is no easy way to shrink the structure <= 1024 an it is likely to grow in
the future.
random_adaptors_lock is held.
- Use sx_sleep instead of tsleep in read and write path to allow
another thread that registers a new random adapter when waiting.
Assert that random_adaptor is not NULL after reacquiring the lock.
- Capture EINTR/ERESTART from sx_sleep to allow the blocking cycle be
stopped when user requests so, while there also make short
read/write's return 0.
- Move M_WAITOK allocations out of lock scope.

support for AVX on i386.
- Similar to amd64, move the FPU save area out of the PCB and instead
store saved FPU state in a variable-sized buffer after the PCB on the
stack.
- To support the variable PCB location, alter the locore code to only use
the bottom-most page of proc0stack for init386(). init386() returns
the correct stack pointer to locore which adjusts the stack for thread0
before calling mi_startup().
- Don't bother setting cr3 in thread0's pcb in locore before calling
init386(). It wasn't used (init386() overwrote it at the end) and
it doesn't work with the variable-sized FPU save area.
- Remove the new-bus attachment from npx. This was only ever useful for
external co-processors using IRQ13, but those have not been supported
for several years. npxinit() is now called much earlier during boot
(init386()) similar to amd64.
- Implement PT_{GET,SET}XSTATE and I386_GET_XFPUSTATE.
- npxsave() is now only called from context switch contexts so it can
use XSAVEOPT.
