8ad895a6a9 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.

6beeb2a4cd 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?

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.

fe0d408987 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.

3e2c6ca3b9 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.

ae8e1d08d7 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

15317dd875 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.

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.

46eede0058 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.)

f711d546d2 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.

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.

2127f26023 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.

08b6a4cbee * 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.

99d11cde56 Major changes to the generic device framework for FreeBSD/alpha:
* Eliminate bus_t and make it possible for all devices to have
  attached children.

* Support dynamically extendable interfaces for drivers to replace
  both the function pointers in driver_t and bus_ops_t (which has been
  removed entirely.  Two system defined interfaces have been defined,
  'device' which is mandatory for all devices and 'bus' which is
  recommended for all devices which support attached children.

* In addition, the alpha port defines two simple interfaces 'clock'
  for attaching various real time clocks to the system and 'mcclock'
  for the many different variations of mc146818 clocks which can be
  attached to different alpha platforms.  This eliminates two more
  function pointer tables in favour of the generic method dispatch
  system provided by the device framework.

Future device interfaces may include:

* cdev and bdev interfaces for devfs to use in replacement for specfs
  and the fixed interfaces bdevsw and cdevsw.

* scsi interface to replace struct scsi_adapter (not sure how this
  works in CAM but I imagine there is something similar there).

* various tailored interfaces for different bus types such as pci,
  isa, pccard etc.
