Add missed "rasops1" attribute to smg(4) rasops'fied a year ago.

This fixes silent boot failure on VS3100 with smg(4) framebuffer console.
Should be pulled up to netbsd-10.

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@.
https://mail-index.netbsd.org/port-vax/2023/01/thread1.html#004147

Worth to pullup to netbsd-10.

USB for vax (similar to pmax; no/negligible impact on legacy):
* Add USB device files/majors.
* Make kernel configs with USB work.
* Provide a USB-enabled kernel config.

spelling (DEC called it "TURBOchannel")

Make VAXstation 4000 TURBOchannel adaptor work.
PIO and IRQ tested on VS4000/60 and /96 with TC-USB (slhci) and PMAD-AA (le).
DMA is untested.
vax needs space to be mapped out, so memory space is pre-mapped for TC option
drivers not bus_space'ified yet, also providing custom bus_space methods for
this kludge.

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
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.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

branches: 1.117.6;

branches: 1.115.2;
Patches from Brad Parker to support vax730.

- Separate the COMPAT_13 and COMPAT_16 code into their own files and
compile them only when the relevant config options are set.

- Provide a sendsig_sigcontext() implementation using the existing vax
signal code; it already does the correct thing.

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

Use device_* accessors.

Revert last change.

Add back some includes which were inadvertantly removed.

branches: 1.108.2; 1.108.6;
Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
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.

branches: 1.105.24; 1.105.30;

list it in conf/files instead of in every port's files.*.

branches: 1.98.6;
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.

Remove old dmf/dmz definitions.

branches: 1.96.4;
Give wskbdmap_lk201.c its own attribute.

Argh, dont reference any wscons parts in files.dec yet.

Move the dz driver to dev/dec, since it can be shared with pmax.

Upon further reflection, move udiv/urem to libkern and out of vax/vax.

Rename VAX kernel assembly source from .s to .S (the NetBSD standard)

Switch to MI dev/md_root.c for archs which don't have any special
memory disk hooks (i.e. everything except atari).

- convert usage of "defopt" to "defflag" where the relevant option does
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

- replace "defopt" with "defparam" for options which must take a value,
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

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.

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.

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 :-)

Update for changes to config.

Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

branches: 1.28.2; 1.28.4;
Add clock_subr.c.

New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

Change the way boot device is figured out; now only using DEC numbers
and done when the device get attached.

branches: 1.25.4;
Support for DL11 (-compatible) async ctlr.
Written by Ben Harris (bjh@mail.dotcom.fr).

"md" is declared in sys/conf/files, now.

Add another parent bus for 11/750 (cmi). remove mtc.c.

Update config files for VAX8200 and VAXstations.

Update to match new MSCP device handling.
Remove support for old config system.

Add DZ-11 to GENERIC & files.vax.

Convert all devices according to the changes to config.

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.

Added ns_cksum.c.

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

Support for ka650, tailored in_cksum and removal of a couple needs-count.

maxpartitions added. Kernel now loaded with -Z flag.

DDB file added.

ddb file added.

Reference cninit.c as well as cons.c

Support for tmscp tapes.

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

Program to make a fast convert from new to old config (Ugly!)

add 'maxpartitions' keyword as first 'intesting' thing in the file, to
facilitate the solution of config.new's hardcoded partition number
problems.

Locore.c added.

new RCS ID format.

New filenames; changes applying to 1.o Beta

genconf.c added to files.vax.newconf

Initial VAX port merging.

Add missed "rasops1" attribute to smg(4) rasops'fied a year ago.

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 "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.

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

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 :-)

Update for changes to config.

Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

branches: 1.28.2; 1.28.4;
Add clock_subr.c.

New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.

For the detailed change history, look at the commit log entries for
the is-newarp branch.

Change the way boot device is figured out; now only using DEC numbers
and done when the device get attached.

branches: 1.25.4;
Support for DL11 (-compatible) async ctlr.

Update config files for VAX8200 and VAXstations.

Update to match new MSCP device handling.
Remove support for old config system.

Add DZ-11 to GENERIC & files.vax.

Convert all devices according to the changes to config.

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.

Added ns_cksum.c.

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

Support for ka650, tailored in_cksum and removal of a couple needs-count.

maxpartitions added. Kernel now loaded with -Z flag.

DDB file added.

ddb file added.

Reference cninit.c as well as cons.c

Support for tmscp tapes.

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

Program to make a fast convert from new to old config (Ugly!)

add 'maxpartitions' keyword as first 'intesting' thing in the file, to
facilitate the solution of config.new's hardcoded partition number
problems.

Locore.c added.

new RCS ID format.

New filenames; changes applying to 1.o Beta

genconf.c added to files.vax.newconf

Initial VAX port merging.

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@.
https://mail-index.netbsd.org/port-vax/2023/01/thread1.html#004147

Worth to pullup to netbsd-10.

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

* Make kernel configs with USB work.
* Provide a USB-enabled kernel config.

spelling (DEC called it "TURBOchannel")

Make VAXstation 4000 TURBOchannel adaptor work.
PIO and IRQ tested on VS4000/60 and /96 with TC-USB (slhci) and PMAD-AA (le).
DMA is untested.
vax needs space to be mapped out, so memory space is pre-mapped for TC option
drivers not bus_space'ified yet, also providing custom bus_space methods for
this kludge.

Welcome to 5.99.53! Merge rmind-uvmplock branch:

- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.

- Simplify locking in some pmap(9) modules by removing P->V locking.

- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
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.

- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.

Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

branches: 1.117.6;
A big bunch of bugfixes from Johnny Billquist. Highlights:

- Fix a hard-tracked bug causing VAXen to hang at splhigh.

branches: 1.116.2; 1.116.4;
- add siginfo translation for all arithmetic faults and traps.
- skip the current instruction for all faults, to avoid infinite loops on
SIGFPE (from OpenBSD)

branches: 1.115.2;
Patches from Brad Parker to support vax730.

- Separate the COMPAT_13 and COMPAT_16 code into their own files and
compile them only when the relevant config options are set.

- Provide a sendsig_sigcontext() implementation using the existing vax
signal code; it already does the correct thing.

Make the emulations, exec formats, coredump, NFS, and the NFS server
into modules. By and large this commit:

- shuffles header files and ifdefs
- splits code out where necessary to be modular
- adds module glue for each of the components
- adds/replaces hooks for things that can be installed at runtime

branches: 1.112.2; 1.112.4;

Rototill the vax code. Switch to devicet/PRIV_ALLOC. Cleanup vax autoconf
code. Move to prototype definitions. staticfy, constify, avoid casting.
Use device_* accessors.

Revert last change.

Add back some includes which were inadvertantly removed.

branches: 1.108.2; 1.108.6;
Since files.wscons et al. are included by ~all ports anyway, include
them in the mi "files" file, and remove include statements from md files.
These shouldn't pull in additional kernel code when not in use, so it
shouldn't do any harm except a risk of namespace collisions which
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.

branches: 1.105.24; 1.105.30;
Partially adapt the VAX port to the newlock2 changes. These are untested

Add lcspx console device driver.

Add SA_SIGINFO support for VAX.

Since everyone uses clock_subr.c (or should, if they don't currently),
list it in conf/files instead of in every port's files.*.

branches: 1.98.6;
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.

Remove old dmf/dmz definitions.

branches: 1.96.4;
Give wskbdmap_lk201.c its own attribute.

Argh, dont reference any wscons parts in files.dec yet.

Move the dz driver to dev/dec, since it can be shared with pmax.

Upon further reflection, move udiv/urem to libkern and out of vax/vax.

Rename VAX kernel assembly source from .s to .S (the NetBSD standard)

Switch to MI dev/md_root.c for archs which don't have any special
memory disk hooks (i.e. everything except atari).

- convert usage of "defopt" to "defflag" where the relevant option does
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

- replace "defopt" with "defparam" for options which must take a value,
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

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.

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.

Partially adapt the VAX port to the newlock2 changes. These are untested
but they do at least compile.

Remove RASTERCONSOLE support from the pmax port.

welcome to syscall_intern.

branches: 1.102.4; 1.102.6; 1.102.8; 1.102.10;
merge ktrace-lwp.

branches: 1.101.16;
Add lcspx console device driver.

Add SA_SIGINFO support for VAX.

Since everyone uses clock_subr.c (or should, if they don't currently),
list it in conf/files instead of in every port's files.*.

branches: 1.98.6;
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.

Remove old dmf/dmz definitions.

branches: 1.96.4;
Give wskbdmap_lk201.c its own attribute.

Argh, dont reference any wscons parts in files.dec yet.

Move the dz driver to dev/dec, since it can be shared with pmax.

Upon further reflection, move udiv/urem to libkern and out of vax/vax.

Rename VAX kernel assembly source from .s to .S (the NetBSD standard)

Switch to MI dev/md_root.c for archs which don't have any special
memory disk hooks (i.e. everything except atari).

- convert usage of "defopt" to "defflag" where the relevant option does
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

- replace "defopt" with "defparam" for options which must take a value,
as config(8) will warn for value-less defparam options
- minor whitespace/formatting cleanup
- consolidate opt_tcp_recvspace.h and opt_tcp_sendspace.h into opt_tcp_space.h

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

if_il.c lives in dev/qbus now, and is mentioned in dev/qbus/files.uba.
Remove commented out line for it.

branches: 1.86.2;
remove interlan np100 entry as the referenced files don't exist

Add a VAXANY type. Eventually to used in INSTALL / GENERIC to easily
include support for all VAX platforms

Add ka610, remove TS11.

MD in4_cksum.

Compile vsbus_dma.c if vax53, hinted by Michael Kukat.

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
