ttyB* minor numbers change; be sure to rerun MAKEDEV if you do not
upgrade with bsd.rd

Adapted from NetBSD by miod@

Split early startup code out of locore.S into locore0.S. Adjust link
run so that this locore0.o is always at the start of the executable.
But randomize the link order of all other .o files in the kernel, so
that their exec/rodata/data/bss segments land all over the place.

Late during kernel boot, smash the startup code with traps so that
it does not point to the other randomly placed code. It has be smashed,
because alpha (insecurely in my view) runs in the KSEG0 space.

As a result, the internal layout of every newly build bsd kernel is
different from past kernels. Internal relative offsets are not known
to an outside attacker. The only known offsets are in the startup code,
which is gone.

Ramdisk kernels cannot be compiled like this, because they are gzip'd.
When the internal pointer references change, the compression dictionary
bloats and results in poorer compression.

Blink leds on the DEC 3000 models (three different led types).

Rework that way that agp attaches.

previously, we had a static list of pcidevs and which agp driver would
be interanlly attached. Instead, split the agp drivers so they work like
audio(4), where we attach a driver, which sets up some callbacks and
initial state, then attaches the interface (agp(4)). Since this allows
us to attach different drivers in different places, and give them
/proper/ probe functions move most of the drivers back to attaching at
pchb, where they should, and intagp (formerly agp_i810) stays attaching
at vga, since it's part of the intel integrated graphics chips.

Diff shrinks the kernel slightly, gets rid of the annoying "no integrated
graphics" warning, and allows more cleanup later.

Tested by many. fix for alpha build (the only other vga_pci.c consumer)
suggested by miod.

Add code to walk the eisa configuration, from NetBSD. This configuration

directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,

There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.

Diff shrinks the kernel slightly, gets rid of the annoying "no integrated
graphics" warning, and allows more cleanup later.

Tested by many. fix for alpha build (the only other vga_pci.c consumer)
suggested by miod.

Add code to walk the eisa configuration, from NetBSD. This configuration
is not used yet, but this seems to ``warm up'' the eisa chips so that
accesses to the eisa bus later do not cause machine checks.

Remove stray "attach com at isapnp with com_isapnp".
ok miod@

crank maxusers on some architectures

Unifdef NO_IEEE in the libkern softfloat code, and put an appropriate rule
in files.alpha to compensate for NO_IEEE kernels.

This will allow the softfloat code to be used by other platforms than alpha.

libkern, begone. Move to a new mechanism where config(8)'s "file"
directive can select between MI and MD versions of these files. At
the same time, adjust the boot programs to pick exactly what they need,
instead of the 7 or 8 mechanisms previously used.

There will be some fallout from this, but testing it all by myself is a
ridiculously slow process; it will be finished in-tree.

Various developers were very nice and avoided making fun of me when I
was gibbering in the corner..

Better dependency rules in files.alpha, also point to cpuconf.c in the
source tree instead of copying it to the kernel compilation directory for
no good reason.

Only compile badaddr() if we have support for TurboChannel, apecs, cia or lca,
as they are the only users of badaddr(); shrinks RAMDISKB a little more.

Remove dead isabeep driver and unused isabeep() function.

Add support for PCI NE2000 clones. I finally got around to doing this :-)
Tested on alpha, should work on i386 as well. Note that we treat
a PCI NE2000 as a 16-bit card for now since the driver can not
deal with > 16 bit cards. To fix this isa16bit in ed_softc needs to
be changed to bus_width (in bytes). I plan to do this as part
of the split ed driver.

Initial revision

Switch DEC 3000 (TURBOchannel) alpha serial code to MI z8530 code.

ttyB* minor numbers change; be sure to rerun MAKEDEV if you do not
upgrade with bsd.rd

Adapted from NetBSD by miod@

Split early startup code out of locore.S into locore0.S. Adjust link
run so that this locore0.o is always at the start of the executable.
But randomize the link order of all other .o files in the kernel, so
that their exec/rodata/data/bss segments land all over the place.

Late during kernel boot, smash the startup code with traps so that
it does not point to the other randomly placed code. It has be smashed,
because alpha (insecurely in my view) runs in the KSEG0 space.

As a result, the internal layout of every newly build bsd kernel is
different from past kernels. Internal relative offsets are not known
to an outside attacker. The only known offsets are in the startup code,
which is gone.

Ramdisk kernels cannot be compiled like this, because they are gzip'd.
When the internal pointer references change, the compression dictionary
bloats and results in poorer compression.

"It's not the years, honey; it's the mileage."

bluetooth support doesn't work and isn't going anywhere. the current
design is a dead end, and should not be the basis for any future support.
general consensus says to whack it so as to not mislead the unwary.

Work in progress work towards SMP, heavily based upon NetBSD. The MP kernel
will boot multiuser, but will deadlock under load, and I can't find my
mistake yet.

remove iop(4) driver. it is entirely unmaintained and supports something
which basically doesn't exist at all.

Include files.agp and files.drm from files.pci. Makes sure "drm.h" gets

remove compat_osf1 support from the kernel
ok deraadt miod

Blink leds on the DEC 3000 models (three different led types).

Rework that way that agp attaches.

previously, we had a static list of pcidevs and which agp driver would
be interanlly attached. Instead, split the agp drivers so they work like
audio(4), where we attach a driver, which sets up some callbacks and
initial state, then attaches the interface (agp(4)). Since this allows
us to attach different drivers in different places, and give them
/proper/ probe functions move most of the drivers back to attaching at
pchb, where they should, and intagp (formerly agp_i810) stays attaching
at vga, since it's part of the intel integrated graphics chips.

Diff shrinks the kernel slightly, gets rid of the annoying "no integrated
graphics" warning, and allows more cleanup later.

Tested by many. fix for alpha build (the only other vga_pci.c consumer)
