1a351c9ee4 Make the d_flags of mem devices D_DISK to signify that they are disk-like
random-seekable devices. This lets dd(1) know it can seek on them. It
also affects spec_vnopen() (IIRC), but only makes the path of execution smaller,
and does not change its behavior. This is when securelevel >= 2.

03c6be5cdc Some PnP BIOSsen return garbage in the high byte of the number-of-devices
field (or don't set the high byte at all).  Clear it to avoid reporting
a silly number of devices.

ebb30c0b3a Add the CR4 values for P3 SIMD enabling support. FXSR tells the cpu that
the OS does FXSAVE/FXRESTOR instructions (fast FPU save/restore) during
context switching and also enables SIMD since this enables saving the
extra CPU context that isn't saved with normal FPU regs.  The other
enables the SIMD instructions to use exception 16 (FPU) error reporting.
Note, this doesn't turn on SIMD, just defines the bits.

e5a9fd5435 This commit adds driver support for PCI fast ethernet NICs based on
the Davicom DM9100 and DM9102 chipsets, including the Jaton Corporation
XPressNet. Datasheet is available from www.davicom8.com.

The DM910x chips are still more tulip clones. The API is reproduced
pretty faithfully, unfortunately the performance is pretty bad. The
transmitter seems to have a lot of problems DMAing multi-fragment
packets. The only way to make it work reliably is to coalesce transmitted
packets into a single contiguous buffer. The Linux driver (written by
Davicom) actually does something similar to this. I can't recomment this
NIC as anything more than a "connectivity solution."

This driver uses newbus and miibus and is supported on both i386
and alpha platforms.

9555e59a1e This commit adds driver support for the Silicon Integrated Systems
SiS 900 and SiS 7016 PCI fast ethernet chipsets. Full manuals for the
SiS chips can be found at www.sis.com.tw.

This is a fairly simple chipset. The receiver uses a 128-bit multicast
hash table and single perfect entry for the station address. Transmit and
receive DMA and FIFO thresholds are easily tuneable. Documentation is
pretty decent and performance is not bad, even on my crufty 486. This
driver uses newbus and miibus and is supported on both the i386 and
alpha architectures.

7a2bb3b800 Some reorganization of sysarch() interface:
1. Move definitions of struct i386_*_args to the header file sysarch.h,
   since they are part of the sysarch API. struct i386_get_ldt_args and
   i386_set_ldt_args were identical, therefore make them into one
   struct i386_ldt_args. Libc should use these definitions as well.
2. Return a more sensible EOPNOTSUPP for unknown operations.

Doug Rabson
4249382df0 This represents essentially a complete rewrite of the ISA PnP code. The
new system is integrated with the ISA bus code more cleanly and allows
the future addition of more enumerators such as PnPBIOS and ACPI.

This commit also enables the new pcm driver since it is somewhat tied to
the new PnP code.

4af396a52d Check that there is memory range support before attempting to perform such
an operation, as a kernel client may not have previously checked the CPU

Also correct the function declaration style for the mem_range functions to
match the rest of this file (oops).

9dcbe2404a Convert DEVFS hooks in (most) drivers to make_dev().
Diskslice/label code not yet handled.

Vinum, i4b, alpha, pc98 not dealt with (left to respective Maintainers)

Add the correct hook for devfs to kern_conf.c

The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.

A few drivers had minor additional cleanups performed relating to cdevsw
registration.

A few drivers don't register a cdevsw{} anymore, but only use make_dev().

ca29e71c56 Take advantage of the apm/npx code and let them identify themselves rather
than having explicit hooks here.
Treat the eisa/isa attach a little differently so that we defer the
decision about to attach eisa/isa to the motherboard directly only if
the PCI probe (if it exists) fails to turn up a PCI->EISA/ISA bridge.
This restores the original device geometry where ISA and/or EISA attach
to their bridge rather than bypassing and going to the root.

23e4757cd7 This commit adds device driver support for the Sundance Technologies ST201
PCI fast ethernet controller. Currently, the only card I know that uses
this chip is the D-Link DFE-550TX. (Don't ask me where to buy these: the
only cards I have are samples sent to me by D-Link.)

This driver is the first to make use of the miibus code once I'm sure
it all works together nicely, I'll start converting the other drivers.

The Sundance chip is a clone of the 3Com 3c90x Etherlink XL design
only with its own register layout. Support is provided for ifmedia,
hardware multicast filtering, bridging and promiscuous mode.

f996ef6395 Loosen up the constructed argument segment generation slightly; rather than
trying to size it intelligently just make it 64k and leave it up to the caller
to ensure that the arguments all fit within that range.

This should resolve the issue that some people were seeing with the PnP BIOS
scan crashing on a large PnP node.

9212e4c73a There may exist two kinds of IBM BlueLightning CPU. One is that 5/2
test does not change undefined flag like Cyrix CPUs.  Another is that
5/2 test changes undefined flag like Intel CPUs.  Latter one could not
be detected and was recognized 486DX CPU.  To solve this,
finishidentcpu() calls identblue() when cpu_vendor is null string
(that is, CPUID instruction is not supported) and cpu == CPU_486.
Tests have been done on IBM BlueLightning CPUs, i486SX and i486DX.
