Remove duplicated / slightly-tweaked loadustp() (load user segment table)
routines from all of the m68k ports using the shared pmap. Instead, in
pmap_init(), set up a function pointer to the appropriate mmu_load_urp*()

Allocalte enough reserved ST-RAM to make the old Xserver work by default.

Instead, check ST-RAM size and TT-RAM size on startup and restrict

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.

No particular reaction for a month on source-changes-d@,

use the m68k-common procfs_machdep.c on all m68k platforms.

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.

pciide_machdep.c depends on pciide_common, not pciide.
Pointed out and fix tested by Marc Recht.

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: 1.103.2;
Defflag M060SP and PANICBUTTON, since the corresponding include files are
now referenced from atari_init.c and machdep.c.
The PANICBUTTON implementation appears to be incomplete, compared to
the other ports which have this option implemented.

Add support for wsdisplay and wskbd for HADES.
Add config option for et4000 with 2MB memory.

Make things work with the new autoconf stuff:
- The pcibus is now called 'pcib' and the isabus 'isab'. Their attributes are
'pcibus' and 'isabus' respectively. This makes the underlying busses
attach again.
- Initialize the parent structure in the config_console() function.
Otherwise we end up without a console.

use a merged sys_machdep.c for all the motorola-MMU m68k platforms.

enhance the common m68k db_memrw.c to handle read-only kernel text
and switch all the motorola-MMU m68k platforms to use it.

merge the 12 copies of vm_machdep.c on the m68k platforms.
clean up some other stuff along the way, including:
- use m68k/cacheops.*, remove duplicates from cpu.h.
- centralize a few declarations in (all the copies of) cpu.h.
- define M68K_VAC on platforms which have a VAC.
- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.

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.

TRY_SCSI_LINKED_COMMANDS is a param, not a flag.

Remove the atari specific incarnation of wdc_isa.c. We don't need it (in
fact it didn't work that well either), all could be done by simply adding the
NOSTREAM options to the flags of the generic ISA frontend.
There was probably to much byteswapping in my brain when I invented this.

We need the fonts for pci_vga too...

Move over to pciide. My CDROM drive wouldn't work with the wdcisa attachment,
but it does work with the pciide attachment.

Split pci_machdep into a generic/hades/milan part. There is much difference
in configspace and interrupt handling.

Add wscons related includes.

Both isa_hades.c and isa_milan.c are also dependent on 'isa' of course...

Split the ISA common attachment stuff and the interrupt handling.
There are too many differences between the Hades and Milan in this area.

fdisa needs-flag...

Move dma.c away from the mainbus floppy and make it a separate entity with
tag 'mbdma'.

files.atari:
Defopt motherboard type and make ym2149.c dependend on 'standard' atari
boards.
Configfiles:
Add pseudo device mouse. It got dropped in the moves by accident.

Wcd attacment code for the Milan. The Milan has the standard dual IDE port
hardware. A Milan specific attachment is needed to modify the iot so that
the streaming methods do a byteswap.
Configure like:
wdcisa0 at isa? port 0x1f0 irq 14
wdcisa1 at isa? port 0x170 irq 15

Add a tag to the fdcisa.c and isa/fd.c files. So they won't be used
unnecessary (and cause trouble).

Conditionalize inclusion of the interrupt handlers for 'kbd', 'zs' and
'ncrscsi' since they are not present on the Milan.

Atari specific stuff to implement the Milan floppy. The Milan uses standard
ISA floppy hardware. Configure as:
fdcisa0 at isa? port 0x3f0 irq 6 drq 2

Expand bus_dma implementation. It will now handle the bounce buffer
extensions needed to make the isa floppy driver on the Milan work.

(Whoops! I missed checking these in when adding the RAID_AUTOCONFIG stuff.)

Oops! Both grfcc and grfet need the generic grfabs layer.

branches: 1.66.2;
Specify the major number of the md-device. Otherwise config(1) won't emit

pseudo-device -> defpseudo, per grammar change in config(8).

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

Add .../dev/mii/files.mii. Needed for support of the 3C590.

Add COMPAT_SVR4 for m68k.

branches: 1.60.4;
First step to a framework that can be used to initialize vga-cards on the
pci-bus. The code is called early in the bootphase and tries to initialize

Added COMPAT_LINUX support.

mv vmebus -> avmebus to make room for MI vmebus implementation (per
reqest of Drochner).

Do not include files.isapnp, this file is now included from files.isa...

Circad Leonardo video driver by 'maximum entropy'.

adapt to LANCE driver split

Crazy Dots driver by Julian Coleman.

Add the 'bus' code for a linear big endian bus (like VME).

Add isapnp stuff (Thomas Gerner)

Use MI wdc-driver.

le_bus.c is dependent on pci & isa.

Major overhaul of the atari bus_space implementation.

Move the bus_* functions from machdep.c to bus.c .

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

Amiga uses the common m68k/sig_machdep.c now. Also moved its definition from
the other 68k ports' files.${port} to arch/m68k/conf/files.m68k.

Update for changes to config.

Build the 68060 support package in the kernel build dir.
XXX PCB_ONFAULT is still hardwired to 64 in netbsd060sp.S.

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.

Add wd-driver. The driver is basically the driver present in the arm32
port (Thanks Mark!) with a few atari specific things and the bad block
handling disabled.

Use m68k/sig_machdep.c

Separate bcopy and copypage stuff from copy.s

New ARP system, supports IPv4 over any hardware link.

Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will

Update pathnames of included files for new version of config.

Additions for the et4000 driver & pci-bus.
Note that there are still missing pieces so both et4000 & pci can not yet
be used.

More preps for et-driver.

- Add M68040 option where appropriate
- Reflect changes on the grf/ite/view system for et4000 console support
- Set timezone to 0

adjust to deal with expression support for optional file specs

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Switch to the mi ramdisk driver.

Use files.scsi

Add an nvram-driver. This driver makes it possible to read/write the
configuration info stored in the nvram on the mc146818.

Use files.fpe

Detect type and precence of an FPU in the kernel instead of relying on GEM.

Add Falcon video support. Thanks to Thomas Gerner.

New version of NCR5380-SCSI driver. This version is far more generic than
the previous version. The machine dependent part contains the configuration
for both the TT and FALCON. The configuration files have been changed to
select SCSI-support for either TT, Falcon or both.
The configuration file for the Atari-Falcon will only get _really_ usefull
when the Falcon video part is finished.

Mouse driver added.

Add our own db_memrw.c for ddb.

Add emulator.

Use new files.sunos

Move sunos_machdep.c to m68k

- added sunos_machdep.c for sun3, atari, amiga and mac68k.

- Initialize the parent structure in the config_console() function.
Otherwise we end up without a console.

use a merged sys_machdep.c for all the motorola-MMU m68k platforms.

enhance the common m68k db_memrw.c to handle read-only kernel text
and switch all the motorola-MMU m68k platforms to use it.

merge the 12 copies of vm_machdep.c on the m68k platforms.
clean up some other stuff along the way, including:
- use m68k/cacheops.*, remove duplicates from cpu.h.
- centralize a few declarations in (all the copies of) cpu.h.
- define M68K_VAC on platforms which have a VAC.
- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.

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.

the streaming methods do a byteswap.
Configure like:
wdcisa0 at isa? port 0x1f0 irq 14
wdcisa1 at isa? port 0x170 irq 15

Add a tag to the fdcisa.c and isa/fd.c files. So they won't be used
unnecessary (and cause trouble).

Conditionalize inclusion of the interrupt handlers for 'kbd', 'zs' and
'ncrscsi' since they are not present on the Milan.

Atari specific stuff to implement the Milan floppy. The Milan uses standard
ISA floppy hardware. Configure as:
fdcisa0 at isa? port 0x3f0 irq 6 drq 2

Amiga uses the common m68k/sig_machdep.c now. Also moved its definition from
the other 68k ports' files.${port} to arch/m68k/conf/files.m68k.

Update for changes to config.

Build the 68060 support package in the kernel build dir.
XXX PCB_ONFAULT is still hardwired to 64 in netbsd060sp.S.

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

Use m68k/sig_machdep.c

Separate bcopy and copypage stuff from copy.s

New ARP system, supports IPv4 over any hardware link.

Additions for the et4000 driver & pci-bus.
Note that there are still missing pieces so both et4000 & pci can not yet
be used.

More preps for et-driver.

- Add M68040 option where appropriate
- Reflect changes on the grf/ite/view system for et4000 console support
- Set timezone to 0

adjust to deal with expression support for optional file specs

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Switch to the mi ramdisk driver.

Use files.scsi

Add an nvram-driver. This driver makes it possible to read/write the

Use files.fpe

Detect type and precence of an FPU in the kernel instead of relying on GEM.

Add Falcon video support. Thanks to Thomas Gerner.

New version of NCR5380-SCSI driver. This version is far more generic than
the previous version. The machine dependent part contains the configuration
for both the TT and FALCON. The configuration files have been changed to
select SCSI-support for either TT, Falcon or both.
The configuration file for the Atari-Falcon will only get _really_ usefull
when the Falcon video part is finished.

Mouse driver added.

Add our own db_memrw.c for ddb.

Add emulator.

Use new files.sunos

Move sunos_machdep.c to m68k

Initial revision

Refactor the 68040 writeback() from each m68k port's trap handler into a
shared copy: m68040_writeback(). It is essentially a copy of the Atari

from the mvme68k port.

Tested by rjs@ on a Quadra 950. (Thanks!)

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.

http://mail-index.NetBSD.org/source-changes/2010/11/13/msg014416.html

No particular reaction for a month on source-changes-d@,
no responsible person on atari port, and probably
no active user still using ET4000 on TT030 running NetBSD/atari.

Add support for the EtherNEC.

The EtherNEC is yet another user designed device for Atari machines,
an NE2000 based ISA board connected to Atari's ROM cartridge slot with
simple but ingenious interface and cartridge port adapter, and
it's the most available network solution for the old Atari machines.

See following pages for more details about EtherNEC:

- change kernel address space layout (i.e. move Sysmap to the end of KVA)
to match other m68k ports, which should be done on yamt-km merge
- rework pmap_zero_page(), pmap_copy_page() and some more other functions
to make them compatible with m68k/pmap_motorola.c
- move pmap_bootstrap() into a separate file to allow using either
the atari pmap.c or the m68k common pmap_motorola.c
- use common m68k include files, pcb.h, pmap_motorola.h, and pte_motorola.h

These shouldn't pull in additional kernel code when not in use, so it

use the m68k-common procfs_machdep.c on all m68k platforms.

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.

pciide_machdep.c depends on pciide_common, not pciide.

Add the Hades floppy driver.

Update pathnames of included files for new version of config.

Additions for the et4000 driver & pci-bus.
Note that there are still missing pieces so both et4000 & pci can not yet
be used.

More preps for et-driver.

- Add M68040 option where appropriate
- Reflect changes on the grf/ite/view system for et4000 console support
- Set timezone to 0
- Document FPSP option

misc.c ->stalloc.c

- Add printer device
- Add ym2149 files
- Make ramdisk a pseudo-device

adjust to deal with expression support for optional file specs

New device attachment scheme:

- split softc size and match/attach out from cfdriver into
a new struct cfattach.

- new "attach" directive for files.*. May specify the name of
the cfattach structure, so that devices may be easily attached
to parents with different autoconfiguration semantics.

Switch to the mi ramdisk driver.

Use files.scsi

Add an nvram-driver. This driver makes it possible to read/write the
configuration info stored in the nvram on the mc146818.

Use files.fpe

Detect type and precence of an FPU in the kernel instead of relying on GEM.

Add Falcon video support. Thanks to Thomas Gerner.

New version of NCR5380-SCSI driver. This version is far more generic than
the previous version. The machine dependent part contains the configuration
for both the TT and FALCON. The configuration files have been changed to
select SCSI-support for either TT, Falcon or both.
The configuration file for the Atari-Falcon will only get _really_ usefull
when the Falcon video part is finished.

Mouse driver added.

Add our own db_memrw.c for ddb.

Add emulator.

Use new files.sunos

Move sunos_machdep.c to m68k

- added sunos_machdep.c for sun3, atari, amiga and mac68k.
- changed machdep.c and trap.c to use struct emul.
- remove ep_setup references.
- added struct emul to all emulations.

Added maxpartitions.

Reference cninit.c as well as cons.c
