kqueue provides a stateful and efficient event notification framework
currently supported events include socket, file, directory, fifo,
pipe, tty and device changes, and monitoring of processes and signals
kqueue is supported by all writable filesystems in NetBSD tree
(with exception of Coda) and all device drivers supporting poll(2)
based on work done by Jonathan Lemon for FreeBSD
initial NetBSD port done by Luke Mewburn and Jason Thorpe
to char-cell based vga(4) driver, and fully compatible with existing
apps like XFree86. Currently it supports 80x25, 80x30, 80x40 and 80x50
text modes using emulation. You can enable it by specifying `options
VGA_RASTERCONSOLE' in your kernel config file.
Note that displaying multilingual text doesn't work yet. Necessary
code is already there, but userland stuff and some functionality isn't
ready for prime time yet. I'm working on them.
Define an attribute for each crypto algorithm, and use that attribute
to select the files that implement the algorithm.
* Give the "wlan" attribute a dependency on the "arc4" attribute.
* Give the "cgd" pseudo-device the "des", "blowfish", "cast128", and
"rijndael" attributes.
* Use the new attribute-as-option-dependencies feature of config(8) to
give the IPSEC_ESP option dependencies on the "des", "blowfish", "cast128",
and "rijndael" attributes.
netinet/files.ipfilter, etinet/files.netinet, netinet6/files.netinet6,
and netinet6/files.netipsec.
XXX There are still a few stragglers in conf/files, which are entangled
with other network protocols.
"scsi_core". Make all the files previously selected by the "scsi"
attribute selected by the "scsi_core" attribute. Give the "scsibus"
device the "scsi_core" attribute.
- Split if_fmv.c into MI/MD part and add ISA-PnP attachment for FMV-183.
(XXX FMV-184 is not tested. It would require extra media-select functions..)
- Fix probe functions of fmv_isa so that FMV-181A/182A will also match.
Fixes port-i386/9476.
- Eliminate wi_hostap.c since most of the code are duplicated with
net/if_ieee80211subr.c
- Station for Infrastructure network and IBSS also use service functions
as much as possible to be consistent with other wireless drivers.
Now WEP works for station/ibss/hostap.
Setup sequence obtained from Krups OFW with some CyberPro-specific
magic from Linux driver. The driver still has a lot of hardcoded
stuff, but it is useful enough to bring up wscons on netwinder.
XXX: Proper console attachment needs to be written (the driver was
originally developed on sparc, where our approach to attaching console
is totally different).
Caveat emptor!
This merge changes the device switch tables from static array to
dynamically generated by config(8).
- All device switches is defined as a constant structure in device drivers.
- The new grammer ``device-major'' is introduced to ``files''.
device-major <prefix> char <num> [block <num>] [<rules>]
- All device major numbers must be listed up in port dependent majors.<arch>
by using this grammer.
- Added the new naming convention.
The name of the device switch must be <prefix>_[bc]devsw for auto-generation
of device switch tables.
- The backward compatibility of loading block/character device
switch by LKM framework is broken. This is necessary to convert
from block/character device major to device name in runtime and vice versa.
- The restriction to assign device major by LKM is completely removed.
We don't need to reserve LKM entries for dynamic loading of device switch.
- In compile time, device major numbers list is packed into the kernel and
the LKM framework will refer it to assign device major number dynamically.
from if_ieee80211subr.c, since "wi" devices implement the 802.11
protocol in firmware (for the most part). So, remove the wlan attribute,
which saves a fair bit of kernel text.
counters. These counters do not exist on all CPUs, but where they
do exist, can be used for counting events such as dcache misses that
would otherwise be difficult or impossible to instrument by code
inspection or hardware simulation.
pmc(9) is meant to be a general interface. Initially, the Intel XScale
counters are the only ones supported.

the block comment at the top of the file:
This module provides kernel support for testing network
throughput from the perspective of the kernel. It is
similar in spirit to the classic ttcp network benchmark
program, the main difference being that with kttcp, the
kernel is the source and sink of the data.
Testing like this is useful for a few reasons:
1. This allows us to know what kind of performance we can
expect from network applications that run in the kernel
space, such as the NFS server or the NFS client. These
applications don't have to move the data to/from userspace,
and so benchmark programs which run in userspace don't
give us an accurate model.
2. Since data received is just thrown away, the receiver
is very fast. This can provide better exercise for the
sender at the other end.
3. Since the NetBSD kernel currently uses a run-to-completion
scheduling model, kttcp provides a benchmark model where
preemption of the benchmark program is not an issue.
There is a companion "kttcp" user program which uses the kttcp
pseudo-device.
Largely written by Frank van der Linden, with some modifications
from me.
found on many (all?) of PCI-based ATI graphics cards. It is fully optional

- Temporarily remove `quirk' mechanism. Similar code already exists
in pci_quirks.c.
Makefiles. The main feature added by these targets is that they cover
ONLY the source files used for a given kernel and no other. Thus when
examining MD routines provided by all machines, you will see only
those applicable for your kernel.
behavior changes:
- two iocts used by ndp(8) are now obsolete (backward compat provided).
use sysctl path instead.
- lo0 does not get ::1 automatically. it will get ::1 when lo0 comes up.
by default, and can be enabled by adding the SOSEND_LOAN option to your
kernel config. The SOSEND_COUNTERS option can be used to provide some
instrumentation.
Use of this option, combined with an application that does large enough
writes, gets us zero-copy on the TCP and UDP transmit path.

management bits, and doesn't support older controllers, but that shouldn't
be hard to fix.

If is restricted to SIOP which implement the load/store instruction, and
has 10 scratch registers (basically, 825 and newer, possibly 770).
It implements a different interface between host and script, using a real
ring for command starts, and improved support for reconnect which will allow
256 tag per device. It uses interrupt on the fly to signal complete command,
which allows several commands to be serviced per interrupt and doesn't require
the script to stop to signal command completion.

B-channel and D-channel drivers separately) split the Fritz!PCI card

The new device is called "ifpci" and uses the same D-channel driver as the
isic devices, but has it's own B-channel driver.

Move the BRI registry from layer 2 (duh!) to layer 4, so active cards

using one word as both attribute and device doesn't work well,
radio.c is pulled in even with no such device in the configuration,
and the kernel doesn't link due to missing "radio_cd".
So call the attribute "radiodev" to avoid confusion.
podulebus Ethernet cards. This replaces the NE2000 memory-access routines

This code should perhaps be merged into ne2000.c, but presumably most NE2000
clones won't need it.

target, and tweaking the warnings flags (cesfic, amigappc, and the arm
ports are a little less warning resistant).
Oh, and let's `install' the kernel into ${DESTDIR} if someone says
`make install'. We have to think about cross-compilers here.
not support a value (e.g., it's to be used as "options FOO" instead of
"options FOO=xxx"). options that take a value were converted to
defparam recently.
- minor whitespace & formatting cleanups
that empty values for TEXTADDR and DATAADDR (and ENTRYPOINT) will not
screw things up. Add support for SYSTEM_LD_TAIL_EXTRA which some
ports (not yet converted) are using. Add support for GENASSYM_EXTRAS

- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h
- replace opt_kgdb_machdep.h with opt_kgdb.h
- defparam opt_kgdb.h:
KGDB_DEV KGDB_DEVNAME KGDB_DEVADDR KGDB_DEVRATE KGDB_DEVMODE
- move from opt_ddbparam.h to opt_ddb.h:
DDB_FROMCONSOLE DDB_ONPANIC DDB_HISTORY_SIZE DDB_BREAK_CHAR SYMTAB_SPACE
- replace KGDBDEV with KGDB_DEV
- replace KGDBADDR with KGDB_DEVADDR
- replace KGDBMODE with KGDB_DEVMODE
- replace KGDBRATE with KGDB_DEVRATE
- use `9600' instead of `0x2580' for 9600 baud rate
- use correct quotes for options KGDB_DEVNAME="\"com\""
- use correct quotes for options KGDB_DEV="17*256+0"
- remove unnecessary dependancy on Makefile for kgdb_stub.o
- minor whitespace cleanup
build features (such as ross's DEBUGLIST) can easily be applied to all
