92ad4dfbd1 Make the device name in an isa_device a const char * instead of a char *

9a94c9c5c3 - Remove the inthand2_t type and use the equivalent driver_intr_t type from
newbus for referencing device interrupt handlers.
- Move the 'struct intrec' type which describes interrupt sources into
  sys/interrupt.h instead of making it just be a x86 structure.
- Don't create 'ithd' and 'intrec' typedefs, instead, just use 'struct ithd'
  and 'struct intrec'
- Move the code to translate new-bus interrupt flags into an interrupt thread
  priority out of the x86 nexus code and into a MI ithread_priority()
  function in sys/kern/kern_intr.c.
- Remove now-uneeded x86-specific headers from sys/dev/ata/ata-all.c and
  sys/pci/pci_compat.c.

e60463deed Redo the isa compat driver shim so that each driver is self contained
and does not require that evil list of drivers in isa_compat.h.
It uses the same strategy that pci drivers use, namely a
COMPAT_ISA_DRIVER() macro that creates the glue on the fly.
Theoretically old-style isa drivers should be preloadable now.

80060e8897 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.

af88e209a2 Zap isa_device -> id_conflicts. The sole user of it (userconfig) never
actually used it since the only device that specified it (vga0) was marked
as "FLG_INVISIBLE" in userconfig and therefore never shown.

isa_device->id_ri_flags and RI_FAST were not implemented and did nothing.
The two drivers that were mistakenly thinking this was working were
cy.c and loran.c - these should be converted to newbus.

664a31e496 Change #ifdef KERNEL to #ifdef _KERNEL in the public headers. "KERNEL"
is an application space macro and the applications are supposed to be free
to use it as they please (but cannot).  This is consistant with the other
BSD's who made this change quite some time ago.  More commits to come.

479232a2e7 GC some unused stuff relating to the old conflict checking and other lint.
Change haveseen_isadev() to something a little easier to emulate.
Store the device_t for the wrapper in isa_device.
Implement a replacement for haveseen_isadev - namely haveseen_ioport()
which takes a port size as an extra argument for a proper range check.
This (haveseen_ioport()) has not been tested, but I think it'll work.

54a8c69347 Stage 1 of a cleanup of the i386 interrupt registration mechanism.
Interrupts under the new scheme are managed by the i386 nexus with the
awareness of the resource manager.  There is further room for optimizing
the interfaces still.  All the users of register_intr()/intr_create()
should be gone, with the exception of pcic and i386/isa/clock.c.

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.

084d9853ca Don't declare isa device structs or isa interrupt handlers in <sys/conf>,
and don't depend on them being declared there.  This will cause lots of
warnings for a few minutes until config is updated.  Interrupt handlers
should never have been configured by config, and the machine generated
declarations get in the way of changing the arg type from int to void *.

4c9340d45c Add support for shared interrupts to the kernel. This code is meant
be (eventually) architecture independent. It provides an emulation
of the ISA interrupt registration function register_intr(), but that
function does no longer manipulated the interrupt controller and
interrupt descriptor table, but calls the architecture dependent
function setup_icu() for that purpose.

After the ISA/EISA bus code has been modified to directly call the new
interrupt registartion functions (intr_create() and intr_connect()),
the emulation of register_intr() should be dropped.

The C level interrupt handler function should take a (void*) argument,
and the function pointer type (inthand2_t) should defined in some  other
place than isa_device.h.

This commit is a pre-requisite for the removal of the PCI specific shared
interrupt code.

bb625c15c9 #if'ed out the '#include "opt_smp.h"' line.
The SMP source was merged into 3.0-current last nite and this broke
the make of sbin/dset.

Should make things work for non-SMP case.

People making SMP kernels will need to edit i386/isa/isa_device.h, re-enabling
'#include "opt_smp.h"'.  People making SMP worlds will have to punt for now...
I'm thinking about the real solution, but for now the goal is to NOT break
the world!

477a642cee Man the liferafts! Here comes the long awaited SMP -> -current merge!
There are various options documented in i386/conf/LINT, there is more to
come over the next few days.

The kernel should run pretty much "as before" without the options to
activate SMP mode.

There are a handful of known "loose ends" that need to be fixed, but
have been put off since the SMP kernel is in a moderately good condition
at the moment.

This commit is the result of the tinkering and testing over the last 14
months by many people.  A special thanks to Steve Passe for implementing
the APIC code!
