Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.

branches: 1.82.2;
add a special rule to build m68k/fpu.c to avoid passing -msoft-float.
fixes GCC 6 kernel builds that use this file.

make sure opt_sunkbd.h exists

branches: 1.80.4;
Merge copy-and-pasted fpu_probe() function (to share it among more m68k ports).
Tested on TT030, Sun3/80, and X68030.

branches: 1.79.2;
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: 1.78.32; 1.78.42;
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.

branches: 1.77.28;
Make sun3 use common sun68k/sun68k/isr.c, sun68k/include/cpu.h and
sun68k/include/intr.h.

This also means now sun3 has GENERIC_SOFT_INTERRUPTS support,
so also adapt fd.c and zs.c to MI softintr(9) APIs.

(I'll also update related sources in yamt-splraiseipl branch later)

Make sun3 port use MI mk48txx(4) and intersil7170(4) TOD clock drivers
with bus_space(9) support.
Note clock device name in obio.sun3 is renamed to oclock to use the same
MI attribute (intersil7170) with sun3x.

Tested on 3/80 and TME emulating 3/120 (but not on 3/4xx VME monsters).

First attempt at bus_space(9) support for sun3 with common sun68k/bus.c:
- make sun3 port use common sun68k files as much as possible
- add temporary options _SUN2_ in std.sun2 until sun3 can share all
sun68k files (autoconf.c and isr.c are not yet)
- move sun68kvme declaration temporary as well from files.sun68k to files.sun2
- rename and move sun68k_find_prom_map() function to MD sources since it
can't be shared with sun3
- add bus tag members to struct confargs and initilize them where appropriate

XXX1: MD bus_dma(9) backends are not implemented (yet).
XXX2: more code (obio etc.) should be shared among sun3, sun3x and sun2.

Remove local declaration of the 'fb' attribute now that it's declared
globally.

merge ktrace-lwp.

branches: 1.72.12;
use the m68k-common procfs_machdep.c on all m68k platforms.

Commit changes proposed on tech-kern Thu, 6 Nov 2003
- factor out disksubr.c between sun3, sparc and sparc64. Keep the sun3
groveling code to find a NetBSD disklabel in the first sector (so that it
can find a label at the old sun3 LABELOFFSET) as a fallback is not
label at LABELOFFSET, or sun label is present.
- Fix the sun3 LABELOFFSET (was 64, but the kernel wrote the NetBSD label at
128)
- Make next68k disksubr.c always write a next-compatible disklabel.
- remove #ifdef __sparc__ hack from disklabel(8), and change it to issue
a DIOCWDINFO after writing the disklabel to the raw partition in the
-r/-I case (so that the kernel can convert the label if needed).

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: 1.69.6;
merge all the m68k copies of kgdb_machdep.c.

finish conversion to the common m68k cacheops:
add support for machine-specific flavors of the ops for off-chip caches.
many thanks to Izumi Tsutsui for his help with this.

include wscons definitions, dev/sun/kbdvar.h needs it now.

now that mem_no is emitted by config(8), there is no reason to keep
copy of more or less identical iskmemdev() for every arch; move the function
to spec_vnop.c, and g/c machine-dependant copies

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.

Refactor kbd and mouse drivers so that they can use different middle
layers. Common middle layer shared by kbd_zs and sunkbd is moved into
the new file. Move shared config directives to files.sun and adjust
ports' files.* accordingly.

Need this to support console/Xsun on Mr.Coffee JavaStation.

Tested on sparc, sparc64 (by martin) and sun3 (by jdc).

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.

branches: 1.62.8;
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\""

branches: 1.61.2; 1.61.8;
Add an e_trapsignal member to struct emul, so that emulated processes can
send the appropriate signal depending on the trap type.

branches: 1.60.2;
switch sun3 to ELF. highlight include:
add "%" prefix to register names in assembly code.
change assembly functions to return values in %a0 instead of %d0.
C symbols no longer prepend an underscore, adjust assembly code for this.
32-bit values are now 32-bit aligned instead of 16-bit aligned,
adjust structure packing and padding to override this where necessary.
make EXEC_ELF std, make EXEC_AOUT and COMPAT_AOUT_M68K optional.
use the MI loadfile() instead of several home-grown versions.

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.

Switch to MI md_root.c. Tested on RAMDISK3X kernel.

The declaration for esp has moved to conf/files. (Hi Charles!)

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.)

branches: 1.55.2;
Normalize include paths.

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

split the sun ms/kbd drivers into frontend/backend parts at the serial
interface border, so that other serial interfaces can be attached to the
ms/kbd. zero functional changes and mostly involves moving code around
a bit. tested on the SS2.

this is necessary to attach the PCI ultrasparc keyboard/mouse drivers.

Add COMPAT_SVR4 for m68k.

Normalize path of files.sunos.

branches: 1.50.2; 1.50.4;
Make "dma" a real device so it can attach before esp.

Added COMPAT_LINUX support.

Add xyc to the dev/xy.c line, similar for xd.

adapt to LANCE driver split

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

Merge arch/sun3x into arch/sun3

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.

branches: 1.43.2;
Update for changes to config.

Add Sun3/E stuff, and re-organize.

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: 1.40.2; 1.40.4;
Kill an obsolete comment.

Remove redundant file directives

Add /dev/leds (closes PR#2172 from der Mouse)

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
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.

Use arch/m68k/m68k/sig_machdep.c

Add dev/clock_subr.c

Add bus_subr.c

Add sun3/regdump.c

Add sun3/sig_machdep.c

Replace sun3/kgdb_stub.c with sun3/kgdb_machdep.c

branches: 1.29.4;
Add sun3/sunmon.c (also kill trailing spaces)

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

rename: ramdisk => md

The new cg4 driver does not use dev/bt_subr.c

Changed "../../m68k/fpe/files.fpe" to "arch/m68k/fpe/files.fpe" because of config changes

Make the MI LANCE driver standalone, and use cfattach to resolve
naming conflicts between bus attachments on ports that can have
multiple instances of the LANCE.

New autoconfig design that controls attach order.

adjust to deal with expression support for optional file specs

fix typos in recent attachment changes.

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.

Add some things needed by KGDB

Include m68k/fpe/files.fpe for FPU emulation support (fixes PR 1773)

Update for the new z8530 driver

ncr5380sbc attribute is now defined in sys/conf/files.

The xy goes on VME16, not VME32.

New SCSI driver for the NCR5380, by David Jones.
Does DMA with interrupts. Much faster than our old
driver which did only PIO transfers. (Thanks David!)
Could be used on the amiga, and probably others...

branches: 1.13.2;
Use sys/scsi/files.scsi

Add RAMDISK, move some things around.
Add rd*, xd*, xy* (only rd is done).

New DVMA interface, and various cleanup.

Leave pseudo-device prom in for now (even though it doesn't work)
so config will create prom.h

Retool for native build.

Merged locore code back into locore.s

rename files files for new config/config.old naming

make config -g work, add timesink config

it links with out any unresolved symbols, last few are just stubs
because we aren't likely to get near execing init for a while

toasted a whole load more undefined symbols

added more files. marked idprom as a device-driver

use gas; add support for more stuff

initial commit. little of this actually works
