3e368a3368 Alpha 8200: Reinsert licence from NetBSD that should have been there
to begin with. Redo newbus attachment code so that all the DMA mapping
and further pci attachment is done right. Insert config space functions
(jeez- how do you do type 1 cycles?). Do the interrupt setups, etc.
Basically, this is the core I/O module for 8200s, even though logically
it's the 3rd level down from the nominal principle backplane bus
(turbolaser). Still to be done here: S/G code isn't done yet, so we
better live with 2GB or less primary memory.

47eb9b40b9 Alpha 8200: Remove clause 3 of licence. Redo KFTXX bus attachment
code (merge in progress made in NetBSD since the initial import to
FreeBSD). Create dwlpx as the child device. Of course, if we had
more h/w and time, we could find out whether the child device was
a FutureBus module, etc...Anyone ever actually seen one?

clean MI/MD driver, but it *does* actually work at this time. Updated
to use new make_dev stuff. A CONS_DRIVER declaration is also put in
so that this can be the real console for the 8200s.

87e31f4b90 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
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
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

279ad30025 Removal of sys/device.h
- Move intrhook stuff into kernel.h
- Remove all occurrences of #device <device.h>
- Add kernel.h were necessary (nowhere)
- delete device.h

This file contained the structures for cfdata (old style config) and is no
longer used. It was included by most drivers.

It confuses the remote debugger as the definition of 'struct device' in
device.h is found before the one in bus_private.h.

a2c68c62db This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll
        a few adjustments to these changes in the generic code
        a bump of __FreeBSD_version
        add a couple of FreeBSD tags

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.

7e4a9dced9 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.

693dd58bb3 Continue where Julian left off in July 1998:
Virtualize bdevsw[] from cdevsw.  bdevsw() is now an (inline)
        function.

        Join CDEV_MODULE and BDEV_MODULE to DEV_MODULE (please pay attention
        to the order of the cmaj/bmaj arguments!)

        Join CDEV_DRIVER_MODULE and BDEV_DRIVER_MODULE to DEV_DRIVER_MODULE
        (ditto!)

(Next step will be to convert all bdev dev_t's to cdev dev_t's
before they get to do any damage^H^H^H^H^H^Hwork in the kernel.)

16e3fbd2c1 Suser() simplification:
1:
  s/suser/suser_xxx/

2:
  Add new function: suser(struct proc *), prototyped in <sys/proc.h>.

3:
  s/suser_xxx(\([a-zA-Z0-9_]*\)->p_ucred, \&\1->p_acflag)/suser(\1)/

The remaining suser_xxx() calls will be scrutinized and dealt with
later.

There may be some unneeded #include <sys/cred.h>, but they are left
as an exercise for Bruce.

More changes to the suser() API will come along with the "jail" code.

087d4857e5 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.

982e80577d Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

3331f029dc * Add hooks to allow the X server to access I/O ports and memory.
* Update drivers to the latest version of the bus interface.

The ISA drivers' use of the new resource api is minimal.  Garrett has
some much cleaner drivers which should be more easily shared between
i386 and alpha.  This has only been tested on cia based machines.  It
should work on lca and apecs but I might have broken something.
