c9bf4be3c2 * Factor out the object system from new-bus so that it can be used by
non-device code.
* Re-implement the method dispatch to improve efficiency. The new system
  takes about 40ns for a method dispatch on a 300Mhz PII which is only
  10ns slower than a direct function call on the same hardware.

This changes the new-bus ABI slightly so make sure you re-compile any
driver modules which you use.

35e00e91c8 Connect the ISA and PCI compatability shims to an option. In this case
it's options COMPAT_OLDISA and COMPAT_OLDPCI.  This is meant to be a
fairly strong incentive to update the older drivers to newbus, but doesn't
(quite) leave anybody hanging with no hardware support.  I was talking with
a few folks and I was encouraged to simply break or disable the shims but
that was a bit too drastic for my liking.

a0447a0084 Alpha 8200 port: Until we fix things better, determine which alpha CPU
platform we're running on so we know how many bits to reserve at the top

d801231f79 Put a FYI in the compatability shims so that people are aware that they
are using an old unconverted driver.  Most (if not all) of the drivers
for common hardware are newbus these days.  However, we don't want
to encourage people to take the easy way out and write new drivers
using the shims.  This is just passive "encouragement".

87e31f4b90 Remove the 'ivars' arguement to device_add_child() and

device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know

8bafca417a Backout part of the changes made in 1.111
For unknown devices the output will now be
  pci0: unknown card (vendor=0x109e, dev=0x0878) at 14.1 irq 19
instead of
  pci0: unknown card DD^0878 (vendor=0x109e, dev=0x0878) at 14.1 irq 19

Before this change, the code used to take the PCI vendor id and translate it
into a three letter ASCII name.
For PnP devices, the vendor id _does_ map to a nice ASCII name
(eg Creative Labs PnP ID maps to "CTL", ESS PnP ID maps to "ESS")

But there is no such mapping for PCI devices, as can be seen by the
example above where the Brooktree PCI vendor ID maps to "DD^"

The PCI Special Interest Group confirmed they do not have any mappings
from vendor ID to ASCII.

registration.

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

1b3328c300 Alter the behavior of sys/kern/subr_bus.c:device_print_child()
- device_print_child() either lets the BUS_PRINT_CHILD
	  method produce the entire device announcement message or
	  it prints "foo0: not found\n"

Alter sys/kern/subr_bus.c:bus_generic_print_child() to take on
the previous behavior of device_print_child() (printing the
"foo0: <FooDevice 1.1>" bit of the announce message.)

Provide bus_print_child_header() and bus_print_child_footer()
to actually print the output for bus_generic_print_child().
These functions should be used whenever possible (unless you can
just use bus_generic_print_child())

The BUS_PRINT_CHILD method now returns int instead of void.

Modify everything else that defines or uses a BUS_PRINT_CHILD
method to comply with the above changes.

	- Devices are 'on' a bus, not 'at' it.
	- If a custom BUS_PRINT_CHILD method does the same thing
	  as bus_generic_print_child(), use bus_generic_print_child()
	- Use device_get_nameunit() instead of both
	  device_get_name() and device_get_unit()
	- All BUS_PRINT_CHILD methods return the number of
	  characters output.

6911e1bc28 Implement the BUS_PROBE_NOMATCH method for the PCI bus.
This function is called for each device for which no driver
was found.

Output is similar to the eisa_probe_nomatch() function but with the
added benefit of displaying the assigned IRQ (since PCI gives us
this information up front.)

Output is like so:

pci0: unknown card CPQ0508 (vendor=0x0e11, dev=0x0508) at 11.0 irq 9
pci0: unknown card DFZ0508 (vendor=0x10da, dev=0x0508) at 11.0 irq 9
pci0: unknown card DBL0508 (vendor=0x104c, dev=0x0508) at 11.0 irq 9
pci0: unknown card DDM0011 (vendor=0x108d, dev=0x0011) at 11.0 irq 9

I'm not happy with the 3 lines of macro cruft that got added but
I consider it a temporary annoyance as those bits will be moved to
some place where PCI, EISA and ISAPNP code will be able to use them.

(Not surprisingly, this message is longer than the code in question.)

4d37f3729b On the new Meteor cards, the Philips SAA 7116 is connected to the PCI bus
via an IBM PCI-PCI bridge (82351 or 82352 or 82353)

The driver must identify if it is on a secondary PCI bus, which is
created via the IBM PCI-PCI bridge. If it is, then it must initialise
the IBM PCI-PCI bridge correctly.

To do this, the following new functions are added.
Because they use the pcici_t tag, they are considered 2.2 compatibility APIs
  pcici_t * pci_get_parent_from_tag(pcici_t tag);
  int       pci_get_bus_from_tag(pcici_t tag);

(The _from_tag suffix is used to prevent clashes with similarly named
 newbus PCI API functions)

aa7402e864 In the cyrix Cx5530, there are null (empty) Base address registers before the
base register that controls Ultra-DMA, so we need to examine all possible

cfea775806 Completely replace the PCI bus driver code to make it better reflect
reality. There will be a new call interface, but for now the file
pci_compat.c (which is to be deleted, after all drivers are converted)
provides an emulation of the old PCI bus driver functions. The only
change that might be visible to drivers is, that the type pcici_t
(which had been meant to be just a handle, whose exact definition
should not be relied on), has been converted into a pcicfgregs* .

The Tekram AMD SCSI driver bogusly relied on the definition of pcici_t
and has been converted to just call the PCI drivers functions to access
configuration space register, instead of inventing its own ...

This code is by no means complete, but assumed to be fully operational,
and brings the official code base more in line with my development code.

A new generic device descriptor data type has to be agreed on. The PCI
code will then use that data type to provide new functionality:

1) userconfig support
2) "wired" PCI devices
3) conflicts checking against ISA/EISA
4) maps will depend on the command register enable bits
5) PCI to Anything bridges can be defined as devices,
   and are probed like any "standard" PCI device.

The following features are currently missing, but will be added back,
soon:

1) unknown device probe message
2) suppression of "mirrored" devices caused by ancient, broken chip-sets

This code relies on generic shared interrupt support just commited to
kern_intr.c (plus the modifications of isa.c and isa_device.h).

d6fd1776b0 Add preliminary support for the Orion PCI chip set. It is special in the
way it attaches multiple PCI buses directly to the CPU, instead of having
them hanging off from PCI to PCI bridges. This code is a hack, and will
be obsoleted by the planned rework of the PCI code, which will change the
dealing with PCI to PCI bridges and other special devices significantly.

The patch also adds a kern_devconf entry for PCI bus 0 which is assumed
to be a child of cpu0. The new PCI code will make it possible to hand out
the kern_devconf structure to a pci device being attached, since this is
(regretably, IMHO) required by a few ISA devices.

Finally there are new PCI ids for some Intel chip set devices, which had
already been known to 2.1.5R, but did not make it into -current. This closes

c772748789 Change message "not supported" to "no driver assigned", because
people tend to assume their devices won't work if they see this
message, though it may indicate that those devices just don't
need any PCI driver (e.g. devices that emulate an ISA card, or
that have been initialised by the BIOS and need no further care).

de5bb9367b Forward-declare kern_devconf for use in a prototype. Some drivers
include <pci/pcivar.h> without including <sys/devconf.h> and other
drivers include <pci/pcivar.h> before including <sys/devconf.h> if
certain identifiers are defined.

The devconf headers have convoluted interdependencies.  <sys/devconf.h>
includes <machine/devconf.h> which includes <pci/pcivar.h>.  Most
drivers include <sys/devconf.h> so even isa drivers depend on
<pci/pcivar.h>.  For similar reasons, most drivers depend on another
pci header, on an isa header and on two scsi headers.

6e667246cd Completely new PCI code:
1) Supports PCI to PCI bridge devices (and tries to initialise them,
   even if the BIOS is brain dead).
2) Supports shared PCI interrupts. Interrupt handlers now MUST return
   '0' if they found nothing to do, '1' otherwise.

New features tested with i486 systems based on the Intel Saturn and
a DEC 4channel Ethernet card only, but expected to work on most systems.

The option PCI_REMAP has been removed !

b553215b12 Added a new field to the pci_device struct called pd_shutdown to specify
a device specific shutdown routine for devconf. Assign the value of this
to the kern_devconf struct. Implement a device shutdown routine for if_de
that disables the device. This will stop the device from corrupting memory
after a reboot.

63cf74f14d Added a bit of missing functionality to make this work correctly on a
wider variety of systems.  Include the deivers from pci_intel.c in
pci_config.c (I hope this is what was intended; my system works ok).
Use pmap_mapdev().  Automatically map any large linear frame buffers
or whatnot in VGA-style devices which ordinarily would not have their
own drivers, and don't call not_supported() for them.  (This shuts up
complaints about my Matrox card.)  Include the beginnings of what could
eventually become dynamically-loadable PCI devices.  Allow for the
possibility of PCI devices simply providing a PCI veneer over an existing
ISA device, and shut up about them, too.
Make autoconfiguration text conform more to the style of other supported
buses.
