2961fc5ac4 - Fix the device database parsing code so that it actually works.
- Improve the formatting for devices identified by the database.
 - Fix the pcib_route_interrupt method definition, as an old version
   snuck in here somehow 8(
 - Remove a couple of the vendor/device IDs for PCI:ISA bridges which
   correctly identify themselves.

bb0d0a8efc Next phase in the PCI subsystem cleanup.
- Move PCI core code to dev/pci.
 - Split bridge code out into separate modules.
 - Remove the descriptive strings from the bridge drivers.  If you
   want to know what a device is, use pciconf.  Add support for
   broadly identifying devices based on class/subclass, and for
   parsing a preloaded device identification database so that if
   you want to waste the memory, you can identify *anything* we know
   about.
 - Remove machine-dependant code from the core PCI code.  APIC interrupt
   mapping is performed by shadowing the intline register in machine-
   dependant code.
 - Bring interrupt routing support to the Alpha
   (although many platforms don't yet support routing or mapping
   interrupts entirely correctly).  This resulted in spamming
   <sys/bus.h> into more places than it really should have gone.
 - Put sys/dev on the kernel/modules include path.  This avoids
   having to change *all* the pci*.h includes.

689634a3ea Convert the pcib_{read,write}_config args from signed to unsigned,
like the args to the config space accessors these functions replaced.

This reduces the likelyhood of overflow when the args are used in
macros on the alpha.  This prevents memory management faults when
probing the pci bus on sables, multias and nonames.

f53e8493fb Unconditionally turning on the I/O and memory enable bits in the PCI
command register is too aggressive.  Revert to the previous behaviour, but
leave the new behaviour available as an undocumented option.  It's not
clear what the Right, Right Thing is to do here, but the more conservative
approach is safer.

b6c8407840 Get out the roto-rooter and clean up the abuse of nexus ivars by the
i386/isa/pcibus.c.  This gets -current running again on multiple host->pci
machines after the most recent nexus commits.  I had discussed this with
Mike Smith, but ended up doing it slightly differently to what we
discussed as it turned out cleaner this way.  Mike was suggesting creating
a new resource (SYS_RES_PCIBUS) or something and using *_[gs]et_resource(),
but IMHO that wasn't ideal as SYS_RES_* is meant to be a global platform
property, not a quirk of a given implementation.  This does use the ivar
methods but does so properly.  It also now prints the physical pci bus that
a host->pci bridge (pcib) corresponds to.

honour the register.  It seems that quite a few lazy BIOS writers

not u_long.  On i386's with 64-bit longs, returning u_longs indirectly

previous frame pointer in the stack frame, so it was not easy to debug.

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^"

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 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.

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)

2447bec829 Simplify cdevsw registration.
The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it.  cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.

cdevsw_add() will print an message if the d_maj field looks bogus.

Remove nblkdev and nchrdev variables.  Most places they were used
bogusly.  Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

Move bdevsw() and devsw() functions to kern/kern_conf.c

Bump __FreeBSD_version to 400006

This commit removes:
        72 bogus makedev() calls
        26 bogus SYSINIT functions

if_xe.c bogusly accessed cdevsw[], author/maintainer please fix.

I4b and vinum not changed.  Patches emailed to authors.  LINT
probably broken until they catch up.

4e2f199e0c This commit should be a extensive NO-OP:
Reformat and initialize correctly all "struct cdevsw".

        Initialize the d_maj and d_bmaj fields.

        The d_reset field was not removed, although it is never used.

I used a program to do most of this, so all the files now use the
same consistent format.  Please keep it that way.

Vinum and i4b not modified, patches emailed to respective authors.

49e5f1b929 Use the probe priority mechanism to make sure the chip* probes do not
displace a real driver.
Revert rev 1.109.
Pick up a few things from elsewhere (a couple of SiS id's).

As an *experiment*, have the chip* driver claim (for reporting purposes)
IDE controllers if there isn't another PCI-aware ide or ata driver to
grab them.  I've exported the match function since it could be used from
the ata-all.c code replacing ata_pcimatch() - but I have not touched the
ata code.  I'd like to catch a few more devices this way, including USB
and other bridges etc.

46f40af052 Replace the pcidevice_set linker set based configuration mechanism for old
style pci drivers with a simple one-line change to use a module that
registers itself under new-bus and should in theory enable just about all
of the pci drivers to be loadable (kldload and loader(8)) but without
having the impact of converting the APIs yet.

This also fixes the problem of having undefined variables when only
new-style pci drivers are present.

6182fdbda8 Bring the 'new-bus' to the i386. This extensively changes the way the
i386 platform boots, it is no longer ISA-centric, and is fully dynamic.
Most old drivers compile and run without modification via 'compatability
shims' to enable a smoother transition.  eisa, isapnp and pccard* are
not yet using the new resource manager.  Once fully converted, all drivers
will be loadable, including PCI and ISA.

(Some other changes appear to have snuck in, including a port of Soren's
 ATA driver to the Alpha.  Soren, back this out if you need to.)

This is a checkpoint of work-in-progress, but is quite functional.

The bulk of the work was done over the last few years by Doug Rabson and
Garrett Wollman.

92e81ca475 Let drivers specify interrupt flags (INTR_EXCL and/or INTR_FAST)
using the new pci_map_int_right() variant of pci_map_int().  Fast
interrupts work for PCI devices if and only if they are exclusive.
(The PCI interrupt mux doesn't support fast interrupts and can't
support a mixture of fast and slow interrupts even in principle.)

Don't assume that intrmask_t == unsigned in pci_map_int().
