Driver module as illustrated here:
https://www.sparkfun.com/products/13911
A SCMD module is a ARM SOC simular to a Arduino in front of a motor
driver chip. The single SCMD module can control two motors and up to
16 additional modules can be chained together using an internal I2C
bus. One can interface with the SCMD using tty uart commands, SPI or
I2C. The driver in this commit adds a kernel driver for the I2C and
SPI interfaces. The command line utility provides a set of
convenience commands that support most of the functions of the SCMD
and is able to use the tty uart mode, SPI user land or the included
kernel driver in a uniform manor.
The use of the SCMD module is mostly for small robots and the like,
but it can control anything that is controllable by voltage.
in /etc/rc.conf.d are loaded.
Usually this does not matter as rcvar and name are set to the same value.
For pf_boot and npf_boot, rcvar is set to pf and npf respectively.
Prior to the change, if:
rc.conf contains nfp=YES
rc.conf.d/npf does not exist
Then:
/etc/rc.d/npf_boot rcvar
outputs:
# npf_boot
$npf=YES
If:
rc.conf contains npf=NO (or is not set)
rc.conf.d/npf contains npf=YES
Then:
/etc/rc.d/npf_boot rcvar
outputs:
# npf_boot
$npf=NO
This means that in the latter case, at boot time the npfctl start command
is never run and the firewall is not operational.
sensor such as:

This is a higher priced sensor with a lot of features, including the
ability to do sub-second periodic updates. The driver supports
everything about the sensor except for the alert pin.
As well as offering a dynamic amount of iterations and memory usage,
which fits well with NetBSD's goal of running on a diverse range of
hardware devices, Argon2id offers improved resistance to GPU-based
password cracking and side channel attacks.
Introduce a /dev/efi character device that provides a means for accessing
UEFI RT variable services from userland. Compatible with the FreeBSD ioctl
interface for ease of porting their libefivar and associated tools.
The ioctl interface is defined in sys/efiio.h.
To enable support for this on an arch, the kernel needs `pseudo-device efi`
and the MD EFI implementation needs to register its backend by calling
efi_ops_register(). This commit includes an implementation for Arm.
toor is a backup account to be used in case of trouble.
When root's default shell was changed to from /bin/csh to /bin/sh,
toor lost its purpose.
/rescue/sh is an ideal choice here because it's a static binary,
while we've moved to dynamic linking for the rest of the system.
Discussed a few times over the years on tech-userlevel.
a warning to motd pointing at entropy(7) and give instructions how to
re-generate the (weak) keys after fixing up entropy.
Add a "keyregen" command, which forces regeneration of all host keys
to simplify the replacement of weak keys.
This set is only installed on amd64,i386,evbarm.
This set is installed on minimal installs and on install media, in
case someone needs it for basic driver functionality.
Comments:
Switched to a single MK tunable for it - that is probably unneeded.
An upcoming DRM update will include even fatter firmware, and we'd
like to minimize the impact of it.

From their notes:
All new functionality should be explained by the updated manpage.
The manpage has been refactored a bit: A new section "Directives"
has been added and the information about default hostnames and
IPsec directives has been moved there, and the new file include
directive information is also there.
getconfigent has the most major changes. A newline is no longer
read immediately, but is called only by a "goto more" (inside an
if(false) block). This allows multiple definitions or directives
to exist on a single line for anything that doesn't terminate using
a newline. This means a key-values service definition can be followed
by another key-values service definition, a positional definition,
or an ipsec, hostname, or .include directive on the same line.
memset is no longer used explicitly to clear the servtab structure,
a function init_servtab() is used instead, which uses a C struct
initializer.
The servtab se_group field is its own allocation now, and not just
a pointer into the user:group string.
Refactored some stuff out of getconfigent to separate functions
for use by parse_v2.c. These functions in inetd.c are named with
the form parse_*()
parse_v2.c only has code for parsing a key-values service definition
into a provided servtab. It should not have anything that affects
global state other than line and line_number.
Some function prototypes, structures, and #defines have been moved
from inetd.c to inetd.h.
The function config_root replaces config as the function called on
a config file load/reload. The code removed from the end of
config(void) is now called in config_root, so it is not run on each
recursive config call.
setconfig(void) was removed and its code added into config_root
because that is the only place it is called, and redundant checks
for non-null globals were removed because they are always freed by
endconfig. The fseek code was also removed because the config files
are always closed by endconfig.
Rate limiting code was updated to add a per-service per-IP rate
limiting form. Some of that code was refactored out of other places
into functions with names in the form rl_*()
We have not added any of the license or version information to the
new files parse_v2.c, parse_v2.h, and inetd.h and we have not
updated the license or version info for inetd.c.
Security related:
The behavior when reading invalid IPsec strings has changed. Inetd
no longer exits, it quits reading the current config file instead.
Could this impact program security?
We have not checked for memory leaks. Solomon tried to use dmalloc
without success. getconfigent seemed to have a memory leak at each
"goto more". It seems like inetd has never free'd allocated strings
when throwing away erroneous service definitions during parsing
(i.e. when "goto more" is called when parsing fields). OpenBSD's
version calls freeconfig on "goto more"
(c5eae130d6/usr.sbin/inetd/inetd.c (L1049))
but NetBSD only calls it when service definitions are no longer
needed. This has been fixed. freeconfig is called immediately before
any "goto more". There shouldn't be any time when a servtab is in
an invalid state where freeconfig would break.
be there (and the latter was removed by accident.)
regen for everyone (also picks up missing tgmath.h for many ports.)
fixes build of pkgsrc/databases/mongodb for me.
This exists for compatibility with a Linux interface which was apparently
deprecated in Linux 2.6. There are various mailing list threads going
back to 2004 where the usefulness of this driver is discussed, but
the conclusion is that scanner software has all moved to using ugen(4)
instead, and enabling this driver will not help you scan things.
This enables the use of modules for a significant build performance gain
when building with clang as host compiler or when using HAVE_LLVM=yes.
Switch libc++ to using the copy from the mono-repo.
hierarchy. This is identical to netbsd-GENERIC, except it has been
dbsym'd so that the kernel symbols are available when running under
Qemu (which loads the kernel directly, but does not load the symbol
table).
in order to make both framebuffer and serial consoles happy.
Also, change TERM from vt220 to vt100 for console and constty
in accordance with other ports.
