All devices can now be in GENERIC.

All supported devices.

vax: GENERIC: Enable some features useful for full ATF runs:

- PUFFS and putter
- crypto and swcrypto

Add optoion GENERIC.local include to the end of ~all GENERIC configs

This excludes atari, sgimips, evbmips, evbppc, evbsh3, and hpcarm
all of which have somewhat specific kernel config file layouts

Add comments that "options VAX410" also supports VS3100/m30,m38,m40,m48.

Add a support for gpx(4) color framebuffer found on VAXstation 3100.

Poted from OpenBSD/vax. Note smg(4) monochrome onboard framebuffer
driver is also changed attached only if gpx(4) is not installed
or flags 1 is specified in config files, as OpenBSD did.

Tested on my VAXstation 3100/m30 with and without 8bpp gpx(4).
Revied on port-vax@ and "Please go ahead!" from ragge@.

swwdog(4): Add to GENERIC kernels.

Plus a handful of others that I'm familiar with. Lots of special-
purpose kernels should probably have this too but I'm not going
through all the arm, mips, and ppc evaluation board kernels to see
which ones are relevant.

Omitted from systems I know to be very small:
- sun2/GENERIC
- dreamcast/GENERIC
Feel free to remove it from others that need to be kept smaller.

Compile-tested a few of these just in case:
- alpha/GENERIC
- amd64/GENERIC
- evbmips/OCTEON
- i386/GENERIC
- riscv/GENERIC

PR kern/29702

UFS/LFS dirhash:
- Enable UFS_DIRHASH if the architecture or kernel model specific config
file can use 128MB of RAM or more.
- Remove experimental tag from UFS_DIRHASH; it's been with RUMP kernel
and by a number of NetBSD developers for years.
- Add LFS_DIRHASH if LFS was enabled.
- Be somewhat consistent with FS options order.

vether: Add to kernel configurations

It's only enabled if the kernel enabled bridge AND tap.
Otherwise it's commented out.

Remove references to BRIDGE_IPF, it is now compiled in by default.

Remove FDDI support.

Add il(4). Commented out.

Enable BUFQ_PRIOCSCAN, CARP, Veriexec by default in GENERIC kernel configs.
On ports without a GENERIC kernel config enable in individul files, e.g evbmips.

atari, dreamcast, emips, epoc32, evbppc/VIRTEX*, ia64, luna68x, mvme68k,
mvmeppc, playstation2, riscv, sun2, sun3, x68k, zaurus due to resource
constraints or port infancy.

Add drvctl to kernel which has audio device.
audiocfg(1) requires drvctl(4).

Retire compat_ibcs2, as discussed on tech-kern@. FreeBSD did the same
recently.

Disable compat_ibcs2, it is being retired.

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

Remove support for VERIFIED_EXEC_FP_RMD160, VERIFIED_EXEC_FP_SHA1, and VERIFIED_EXEC_FP_MD5 options.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs

option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

Initial addition of tmpfs, an efficient memory file-system. This project
was developed as part of Google's Summer of Code 2005 program. This
change adds the kernel code, the mount_tmpfs utility, a regression test
suite and does all other related changes to integrate these.

The file-system is still *experimental*. Therefore, it is disabled by
default in all kernels. However, as typically done, a commented-out
entry is added in them to ease its setup.

Note that I haven't commited the required mountd(8) changes to be able
to export tmpfs file-systems because NFS support is still very unstable
and because, before enabling it, I'd like to do some other changes.

Support for VAX 8600/8650 added. Works with lots of Unibus adapters,
and will probably work with Massbus adapters as well. (Not tested,
but it's the same code as for 11/780). Ubareset's may cause crashes
on 8600 also like 11/780, but they are more uncommon. No support
for console RL02 yet, but it's likely to come.

Add VAX780 and DHU11 to the GENERIC file. Put the corresponding
file lines in files.vax.

Add VAX650, mba, hp, ts. Change uba to be *'ed.

DDB file added.

Support for tmscp tapes.

Support for new CPU type (KA630 == uVAXII) added, tape driver.

bring in content of GENERIC.v6 into GENERIC.
remove GENERIC.v6 file (as it is part of GENERIC now).

"faith" interface is commented out by default as it is not really for
general use.
IPsec items are commented out as well, though we can enable "options IPSEC"
without export-related issue ("options IPSEC" will enable authentication
portion only). We may need to think about it again.

if you have problem compiling with INET6 on archs I do not have access to,
please contact me.

XXX what to do with arch/arm32/SHARK{,.v6}?

branches: 1.2.2; 1.2.8;
Add examples for including the kernel crypto bits from either crypto-us
or crypto-intl, commented out, with instructions to use only one, and
adjust the prefix as necessary.

branches: 1.1.2;
kernel configuration for IPv6/IPsec. should be in GENERIC in the future.

Add comments that "options VAX410" also supports VS3100/m30,m38,m40,m48.

Add a support for gpx(4) color framebuffer found on VAXstation 3100.

Poted from OpenBSD/vax. Note smg(4) monochrome onboard framebuffer
driver is also changed attached only if gpx(4) is not installed
or flags 1 is specified in config files, as OpenBSD did.

Tested on my VAXstation 3100/m30 with and without 8bpp gpx(4).
Revied on port-vax@ and "Please go ahead!" from ragge@.

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Add "options COMPAT_70" to all kernel configuration files that
already had "options COMPAT_60".

Bump INSTALL ramdisk size slightly to allow building with DBG=-g.

bump md image size

branches: 1.66.4;
the bogus number police

remove confusing numeric locators where they are unused.

Add "options COMPAT_60" to all kernel configuration files
that already had "options COMPAT_50".

branches: 1.63.2;
Update all kernel configs mentioning WSEMUL_* but not already including
WSDISPLAY_COMPAT_USL using the following rules:
- If WSEMUL_ is commented out, add commented out out WSDISPLAY_COMPAT_USL
- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL

Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.

Now wsconscfg(8) should be able to switch VTs when expected.

Implemented after no objection from tech-kern to the following:

Sync devices with GENERIC, and include bpfilter to allow dhcpcd to work

All apply to vax only:
- Drop KERNFS from INSTALL kernel
- Add dmesg to sysinst ramdisk
- Add 'ramdisk' target to MAKEDEV and use
- Add dhcpcd to sysinst ramdisk
- Drop old install.md script
- Misc install image cleanup (reduce diff to zaurus of all things)

- Add racd* devices for MSCP based CD-ROM drives (RRD40s), as opposed
to mixing them in with the ra* disks, modelled loosely on how MSCP
rx* floppies are handled
- racd* defaults to the same single iso9660 partition as cd*
- Cleanup config option handling slightly so any combination of ra*,
rx* (and now raccd*) can be defined without build errors.
- Avoid ugly printf when disks have all zero disklabel magic number

Bump the ramdisk size so that the contents fits again.

branches: 1.58.2;
WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.57.2;

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

branches: 1.56.2;
dependant -> dependent

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html
for details.

branches: 1.54.2; 1.54.4;
Remove unused count from pseudo-device md.

Remove unused count (invariably "4") from pseudo-device fss.

branches: 1.52.4; 1.52.6;
Changes to MEMORY_RBFLAGS option:
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)

enable USERCONF by default; it's small and extremely useful to have available.

Ensure all INSTALL config files consistantly include PIPE_SOCKETPAIR,
MALLOC_NOINLINE, and VNODE_OP_NOINLINE. The exceptions are when they
include another config files that already defines the options, or if
they are for an embedded board, just define a few extra options, and
do not already define PIPE_SOCKETPAIR.

Change the uba devices from "xx0" to "xx*". Even if they have an exact
csr there may be multiple uba's in a machine and therefore multiple

branches: 1.26.2; 1.26.4;
Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size

Add VAX 4000/200

Enable VS4000/90 SCSI controller in INSTALL kernel.

Ensure all INSTALL* kernels have two ptys, and a note explaining why:
pseudo-device pty 2 # pseudo-terminals (Sysinst needs two)
(Some installers may not be using sysinst, in which case this just reduces
the number of ptys from 16 that are not used to 2 that are not used)
For i386 conf files, no change other than comments.

Use "options<SPACE><TAB>" not "options<TAB>" - noted by simonb.
Move VNODE_OP_NOINLINE and NFS_V2_ONLY into '# Filesystem options' section.
Consistently label '# Filesystem options' and '#File systems' sections.

Ensure all INSTALL config files have (at least) COPTS="-Os", cincluding bebox

Drop -O[01] hacks for vax; no longer necessary for patched GCC 10

PR port-vax/57646: Import major vax toolchain fix by Kalvis Duckmanton

XXXRO: GCC 12 may require hacks for a while, but it turned out that
GCC 12 should be treated differently from older versions; a lot of new
files need -O[01] flags, while some may no longer require it.

I will take a look later.

Note that these hacks are not required if Kalvis's patches for GCC 12
are applied.

Keep doc/HACKS entries for a while (will be sync with update for GCC 12).

set or not, in the same way as libcompat.

- Specify OPT_MODULAR in the port Makefile instead of KERN_AS.

Now, KERN_AS=library is used for kernels without module(7) for all ports.

Abstract out a large chunk of the kernel build machinery so that new
build features (such as ross's DEBUGLIST) can easily be applied to all
ports. This should reduce the complexity of each port's kernel
Makefile considerably. Line counts:

227 arch/i386/conf/Makefile.i386.orig
98 arch/i386/conf/Makefile.i386
227 arch/alpha/conf/Makefile.alpha.orig
99 arch/alpha/conf/Makefile.alpha

102 arch/sparc/conf/Makefile.sparc
215 arch/vax/conf/Makefile.vax.orig
102 arch/vax/conf/Makefile.vax
253 conf/Makefile.kern.inc

Roll i386, alpha, sparc, and vax over to the new build machinery.

Change defaults for kernel compiles. Default all to USETOOLS?=no and have
the etc Makefile override that by putting USETOOLS into $.MAKEOVERRIDES
This way the default for kernel compiles is still to use the installed
toolchain instead of depending on $TOOLDIR. $TOOLDIR can be used by
simply adding USETOOLS=yes to the command line as usual.

Adjust each ports template to set the default no setting and also pull in
bsd.own.mk if they weren't already to ensure they'll build correctly
with the new toolchain setup.

Remove unused extended attributes kernel options

As Masao Uebayashi pointed to me, UFS_EXTATTR_AUTOSTART, LFS_EXTATTR_AUTOSTART
and UFS_EXTATTR_AUTOCREATE are not used anywhere in the code. Remove them
as they have been obsolete for a long time:
UFS_EXTATTR_AUTOSTART was replaced by mount -o extattr
LFS_EXTATTR_AUTOSTART was created to match obsolete UFS_EXTATTR_AUTOSTART
UFS_EXTATTR_AUTOCREATE was replaced by sysctl vfs.ffs.extattr_autocreate

Support for UFS1 extended attributes in GENERIC and GENERIC-like kernels

This change just brings UFS1 extended attribute *support* in the kernel,
extended attributes are not enabled unless three conditions are met:
1) filesystem is UFS1 (newfs -O1)
2) .attribute/system and .attribute/user directories are created at fs root
3) filesystem is mounted with -o extattr

Some GENERIC kernels are obviously memory constrained, the extended
attributes options were not enabled for them, but just added commented out.
(kernel were considered memory constrained if QUOTA option was disabled)

Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up

Update all kernel configs mentioning WSEMUL_* but not already including

- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL

Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.

Now wsconscfg(8) should be able to switch VTs when expected.

- Add racd* devices for MSCP based CD-ROM drives (RRD40s), as opposed
to mixing them in with the ra* disks, modelled loosely on how MSCP
rx* floppies are handled
- racd* defaults to the same single iso9660 partition as cd*
- Cleanup config option handling slightly so any combination of ra*,
rx* (and now raccd*) can be defined without build errors.

the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).

- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.

should be easy to fix.

Preliminatry TC support.

Refactor in_cksum/in4_cksum/in6_cksum implementations:
- All three functions are included in the kernel by default.
They call a backend function cpu_in_cksum after possibly
computing the checksum of the pseudo header.
- cpu_in_cksum is the core to implement the one-complement sum.
The default implementation is moderate fast on most platforms
and provides a 32bit accumulator with 16bit addends for L32 platforms
and a 64bit accumulator with 32bit addends for L64 platforms.
It handles edge cases like very large mbuf chains (could happen with
native IPv6 in the future) and provides a good base for new native
implementations.
- Modify i386 and amd64 assembly to use the new interface.

This disables the MD implementations on !x86 until the conversion is
done. For Alpha, the portable version is faster.

Merge the gehenna-devsw branch into the trunk.

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.

Support to control the leds on VAXstations, taken from Sun3 and ported
to vax by Shinmyoh Koji (yesu@rb3.so-net.ne.jp).

Giant update from Michael Kukat (michael@unixiron.org).
Fixes support for:
MicroVAX 3100m90
MicroVAX 3100m95
VAX 4000/100 (tested)
VAX 4000/105A (tested)
VAX 4000/108
VAX 4000/400 (tested)
VAX 4000/500 (tested)
VAX 4000/600

A bunch of new CPUs that are supported, from Michael Kukat
(michael@unixiron.org). Among them are 4000/400, 4000/500 and 4000/105A.

Add machdep file for procfs. Currently only used for linux-style
/proc/cpuinfo (only active when procfs is mounted with -o linux).
For ports other than the i386 this currently produces an empty
string.

Recent lkkbd/lkms/lkc changes.

Reverse polarity on INSN_EMULATION to NO_INSN_EMULATION. Thus by default
all kernels will have instruction emulation.

Write code to handle unimplemented instructions trapped via SCB vector 0x18.
This may happen on machines missing parts of the instruction set (like
some floating point formats).
Only one new instruction added; POLYD, so that the libm assembly files can
be used on architectures missing that instruction.
Also; include emulation code if compile-time option INSN_EMULATE is defined
instead of trying to match on which cputype it is.
N.B. POLYD isn't fully implemented, just enough to make libm happy.

nmi files.

Enable emulation for everything but 7xx/8xxxx

Add xmi_mainbus.c file.

branches: 1.71.2;
Rename ncr[5380] device to si to more consistent with other ports.
Add VAX660 to cputype.h. Remove needs-flag from si & asc entries.

Put all cputype definitions in one file instead of separate files.
This was becoming unmaintainable.

Code to spin up other CPUs on a VAX 8200 system.
Haven't solved the printf() problem yet, though.

branches: 1.68.2;
Add 4000/200 and 4000/500.

Add "rl" disk.

Add the RAIDframe device major to the machine-dependent config files
so that the right entries get added to dev_name2blk[]. Needed for / on RAID.
(Whoops! I missed checking these in when adding the RAID_AUTOCONFIG stuff.)

expunge vm_offset_t and vm_size_t.
add bus_dma support for the vs4000 dma translation map (sgmap).
enhance the vsbus for the lance to work with it.
remove the sgmap init code from ka46/48/49.c

Allow arch-specific code to specify in4_cksum() like it can specify
in_cksum().

More files that were changed.

defopt VAXnnn so the make depend does the right thing.

Add VS4000 scsi attachment (does not yet work).
Add COMPAT_IBCS2 hook (for running DEC VAX SVR3 images).

branches: 1.60.2;
Support for 4000/90.

Support for ibus-attached LANCE.

Add support for the SGEC.

Clean up all bus handling stuff, it has become a mess the latest years.
Add a new bus; "ibus" that is the internal MicroVAX bus.

smg/lkc must have "qfont".

BI bus has become MI now.

Normalize include paths.

Use uba & mscp code from dev/ instead.

Only declare block major numbers for devices which can be the root device.

bus.h'ify more of the vax code.

Better and more understandable way to find out CPU type.

First towards use of bus.h routines on vax. Allocate DMA memory for
LANCE chip on vaxstations.

branches: 1.48.4;
Buggfixes for VS 4000/VLC. Basic support for VS4000/90 and MV4000/300.
From Michael Kukat.

Change vsbus to take a locator for all devices.
Figure out interrupt vector/mask on vsbus by forcing all devices to
generate interrupts in the match routine, like on unibus.

Basic KA48 (VAXstation 4000 VLC) support.
From Michael Kukat <michael@camaronet.de>

Allocate (almost) all interrupt vectors dynamically. Simplifies much
work when adding support for new machines and devices.

Memory disk support.

Support for KA820 console RX50. From 4.4, ported to NetBSD by Sergey Svishchev.

Support for DWBUA (BI to Unibus adapter) and KLESI-B (TMSCP tape ctlr) added.

Change backplace0 to mainbus0 (for consistency with other ports).
Remove unused function protocols from ka410.h and ka43.h
Fix some ka46 missing references

Support for VS4000/60. Some needs-count -> needs-flag.

Change not-in-tree drier stubs to use needs-flag, not needs-count,
and use needs-count only where acutally used (qvss, qdss, ts-11)

Don't compile in any rasterconsole code.

Rudimentary support for the VS3100 builtin graphics console.

Remove unneccessary file. Remove stale dependency. Disable not-working
devices by default.

Change to use newly committed ln- and dz-drivers.

Add support for QDSS graphic console. Code originated from 4.4BSD,
ported to NetBSD by Boris Gjenero <bgjenero@undergrad.math.uwaterloo.ca>

Remove random.s.

Remove "class" declarations, and add "devclass" declarations where
appropriate. Fix several inconsistencies between device class and
attributes. Mostly from Chris Demetriou.

Split out MSCP floppies as a separate device (rx) instead of handling
them as disk drives. It is now also allowed to change floppies without
the system complaining :-)
