sys/dev/Makefile: Split INCS onto separate lines for ease of sorting.

Use HAVE_NVMM for nvmm headers

Revert previous to make iscsi kernel headers optional again, as
required by kamil.

Now, sanitizer in GCC9 has been fixed differently for MKISCSI=no.

Unconditionally install kernel headers for iSCSI as required by
sanitizer shipped with GCC9.

Fix build release with HAVE_GCC=9 for sun2, where MKISCSI=no by default.

Remove filemon(4).

Discussed on tech-kern:
https://mail-index.NetBSD.org/tech-kern/2020/01/13/msg025938.html

This was never (intentionally) enabled by default, and the design has
some shortcomings. You can get mostly the same results with ktrace,
as in usr.bin/make/filemon/filemon_ktrace.c which is now used instead
of filemon for make's meta mode.

If applications require higher performance than ktrace, or nesting
that ktrace doesn't support, we might consider adding something back
into the vfs system calls themselves, without hijacking the syscall
table. (Might want a more reliable output format too, e.g. one that
can handle newlines in file names.)

Revert the removal of filemon.

Retire filemon, discussed on tech-kern@.

Hook spi.

Add NVMM - for NetBSD Virtual Machine Monitor -, a kernel driver that
provides support for hardware-accelerated virtualization on NetBSD.

It is made of an MI frontend, to which MD backends can be plugged. One
MD backend is implemented, x86-SVM, for x86 AMD CPUs.

We install

/usr/include/dev/nvmm/nvmm.h
/usr/include/dev/nvmm/nvmm_ioctl.h
/usr/include/dev/nvmm/{arch}/nvmm_{arch}.h

And the kernel module. For now, the only architecture where we do that
is amd64 (arch=x86).

NVMM is not enabled by default in amd64-GENERIC, but is instead easily
modloadable.

Sent to tech-kern@ a month ago. Validated with kASan, and optimized
with tprof.

Fix fallout from hid factorisation:
- need to install sys/dev/hid/hid.h for userland
- include it where needed - most of the time in place if usb/usbhid.h

move spkrio.h out of isa

branches: 1.37.2;
Install hdmicecio.h

Split hdaudio and PCI attach glue. Even though the driver was written with
this separation in mind, all of the code lived in sys/dev/pci/hdaudio. Move
common parts to sys/dev/hdaudio and PCI attach glue to sys/dev/pci.

Install filemon.h

Make the test for MKISCSI actually work by including bsd.own.mk and
testing the expanded variable, not just the variable name(!) Fixes the
build for sun2.

Build and install new in-kernel iscsi initiator kernel module and associated
binaries (iscsid, iscsictl) if MKISCSI != no. Initiator can also be built
into a kernel by adding 'pseudo-device iscsi' in kernel configuration.

branches: 1.32.2;
Install dev/i2c/i2c_io.h and implement the API in the iic(4) driver.
Obsolete the I2C_SCAN option as this can now be done from userland.

install dtvio.h, dtvio_demux.h, dtvio_frontend.h

Install netbsd-dm.h file to include/dev/dm so it can be used by public.

Add keylock.h to INCS so that it's actually installed (hi, marc!)

Add bio(4) and associated bioctl(8) from OpenBSD, a driver control block
device controllers, and more specifically raid controllers.
Add a new sensor type, ENVSYS_DRIVE, to report drive status. From OpenBSD.
Add bio and sysmon support to mfi(4). This allow userland to query
status for drives and logical volumes attached to a mfi(4) controller. While
there fix some debug printfs in mfi so they compile.
Add bio(4) to amd64 and i386 GENERIC.

Add the 'lockstat' driver, which collects basic information about lock events.

Initial import of bluetooth stack on behalf of Iain Hibbert. (plunky@,
NetBSD Foundation Membership still pending.) This stack was written by
Iain under sponsorship from Itronix Inc.

The stack includes support for rfcomm networking (networking via your
bluetooth enabled cell phone), hid devices (keyboards/mice), and headsets.

Drivers for both PCMCIA and USB bluetooth controllers are included.

Abstract the interface between pckbc(4), and the pckbd(4) and pms(4)
drivers that attach to it. This allows for other host interface chips
that use the same keyboards and mice, such as the ones in the ARM
IOMD20, ARM7500, and SA-1111. The PC-compatible driver is still
called pckbc(4), and the new abstraction layer is "pckbport", so the
child devices have moved from sys/dev/pckbc to sys/dev/pckbport, which
also contains some code shared between all host controllers. To avoid
incompatibility, pckbdreg.h is still installed in
/usr/include/dev/pckbc.

In theory, this shouldn't cause any behavioural changes in the drivers
concerned. Thy just use rather more function pointers than before. Tested
on i386 and (with a new host driver) acorn32. Compiled on several other
affected architectures.

The file system snapshot pseudo driver.

Uses a hook in spec_strategy() to save data written from a mounted
file system to its block device and a hook in dounmount().

Not enabled by default in any kernel config.

Approved by: Frank van der Linden <fvdl@netbsd.org>

Include Vinum.

Add dmover to the list of SUBDIRs.

New Feature: add pseudo device for IEEE 1394 isochronous stream and
isochronous reception routine for IEEE 1394 OHCI (fwohci). The
transmission part is under construction.

The minimum configuration options for this feature are:

# IEEE 1394 (i.LINK)
fwohci* at pci? dev ? function ?
pseudo-device fwiso 1

Remove KDIR=, since SYS_INCLUDE=symlinks and KDIR are not supported any more.

Moved MI APM definitions into dev/apm.

Add cgdvar.h to the list of files installed.

This is the "kttcp" network throughput testing pseudo-device. From
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.

Put back all header files defining ioctls

Only install headers which are actually used by our userland. This
saves about 2.2MB under /usr/include/dev/. Discussed on tech-kern@
recently.

I HOPE to get the list right. The headers I left in are ones
used for MI tools and those whose usage I discovered by grep over tree sources.
Feel free to put needed includes back in if you encounter anything which
should not be removed from lists.

Add `sbus' to SUBDIRS.

Add USB.

Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install. (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.) The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change. Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.
