1f601186eb Now that we can bind cdevsw to the individual dev_t, divorce the PERFMON
stuff from mem.c.  If PERFMON is there, it will "steal" a minor from
mem.c, but mem.c doesn't need to know about this.

Fixed type of cmd argument in perfmon_ioctl().

663cbe4fc2 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().

56dea87fc0 Zap a heap of unused cruft now. We don't need the ISA/EISA/PCI hooks
here any more as they are self identifying.  Only PNP remains but that
will be replaced any day now.
Also reword a comment that had been XXX'ed to death to make it clear[er]
why we don't enable interrupts before probing.

9dc99a106d 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.

db4fdbd041 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.

cdea47dc6e This commit adds support for the NetBSD MII abstraction layer and
MII-compliant PHY drivers. Many 10/100 ethernet NICs available today
either use an MII transceiver or have built-in transceivers that can
be programmed using an MII interface. It makes sense then to separate
this support out into common code instead of duplicating it in all
of the NIC drivers. The mii code also handles all of the media
detection, selection and reporting via the ifmedia interface.

This is basically the same code from NetBSD's /sys/dev/mii, except
it's been adapted to FreeBSD's bus architecture. The advantage to this
is that it automatically allows everything to be turned into a
loadable module. There are some common functions for use in drivers
once an miibus has been attached (mii_mediachg(), mii_pollstat(),
mii_tick()) as well as individual PHY drivers. There is also a
generic driver for all PHYs that aren't handled by a specific driver.
It's possible to do this because all 10/100 PHYs implement the same
general register set in addition to their vendor-specific register
sets, so for the most part you can use one driver for pretty much
any PHY. There are a couple of oddball exceptions though, hence
the need to have specific drivers.

There are two layers: the generic "miibus" layer and the PHY driver
layer. The drivers are child devices of "miibus" and the "miibus" is
a child of a given NIC driver. The "miibus" code and the PHY drivers
can actually be compiled and kldoaded as completely separate modules
or compiled together into one module. For the moment I'm using the
latter approach since the code is relatively small.

Currently there are only three PHY drivers here: the generic driver,
the built-in 3Com XL driver and the NS DP83840 driver. I'll be adding
others later as I convert various NIC drivers to use this code.

I realize that I'm cvs adding this stuff instead of importing it
onto a separate vendor branch, but in my opinion the import approach
doesn't really offer any significant advantage: I'm going to be
maintaining this stuff and writing my own PHY drivers one way or
the other.

b51f157bff Implement a new generic mechanism for attaching handler functions to

implementations currently in use.

Retire the at_shutdown family of functions and replace them with
new event handler lists.

c540cb886d 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.

02a6338c26 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.

e6adc2c52e Fix short timeout problems with the pt(4) driver:
- increase the default timeout from 10 seconds to 60 seconds
- add a new kernel option, SCSI_PT_DEFAULT_TIMEOUT, that lets users specify
  the default timeout for the pt driver to use
- add two new ioctls, one to get the timeout for a given pt device, the
  other to set the timeout for a given pt device.  The idea is that
  userland applications using the device can set the timeout to suit their
  purposes.  The ioctls are defined in a new header file, sys/ptio.h

8ffe59d0bf Undo my previous commit and do it differently. Break the ffs() etc macros
into two parts - one to do the bsfl and the other to convert the result
(base 0) to ffs()-like (base 1) in inline C.  This enables the optimizer
to be a lot smarter in certain cases, like where it knows that the argument
is non-zero and we want ffs(known non zero arg) - 1.  This appears to
produce identical code to the old inline when the argument is unknown.

4515ed49ed Welcome devtoname(), to most likely be used when printing information

printf("%x", dev) now becomes printf("%s", devtoname(dev)) because
printing actual information about the device is much more useful then
printing a pointer to an address that would never help the developer debug.

c1329f8c5d Major rewrite.
The first reason for this rewrite is KNF conformance.

The second reason is to avoid redundancy. Each function printed the same
string, with only the syscall name being different. The actual printing is now
performed by a single function, which gets the syscall name as an argument.

The third reason is that of convenience. It's now very easy to add a new
dummy implementation. Just add ``DUMMY(foo);'' to the file. It's also a lot
easier now to see if a syscall has a dummy implementation or not.

The dummies are ordered on syscall number. Please maintain this when adding
new dummies (there're 32 candidates at the time of writing :-)
