Change the devhandle_from_*() functions to also take a "super handle",
from which the newly created handle will inherit it's implementation.
The root implementation for a new handle type is used if an invalid
"super handle" is passed.

Merge thorpej-cfargs2.

Adapt to CFARGS().

Associate the OpenBoot / OpenFirmware node with attached devices
at config_found() time.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
  actually needed.
- Don't be explicit about what interface attribute is attaching if
  the device only has one.  (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
  situations, making is visibly easier to see when indirect config is
  in play, and allowing for future change in semantics.  (As of now,
  this is just a wrapper around config_match(), but that is an
  implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance.  This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Sync with HEAD.

Give config_found() the same variadic arguments treatment as
config_search().  This commit only adds the CFARG_EOL sentinel
to the existing config_found() calls.  Conversion of config_found_sm_loc()
and config_found_ia() call sites will be in subsequent commits.

malloc(9) -> kmem(9) -- just the simple, straightforward conversions for now.

Mostly merge changes from HEAD upto 20200411

in many device attach paths, allocate memory with M_WAITOK instead of M_NOWAIT
and remove code to handle failures that can no longer happen.

merge the ebus@pci attach output to be like most PCI drivers:

ebus0 at pci1 dev 1 function 0
ebus0: Sun Microsystems PCIO Ebus2, revision 0x01

becomes:

ebus0 at pci1 dev 1 function 0: Sun Microsystems PCIO Ebus2, revision 0x01

update from HEAD

src is too big these days to tolerate superfluous apostrophes.  It's
"its", people!

Resync to 2012-11-19 00:00:00 UTC

sync with head

Match the Altera ebus bridge, as found on the Tadpole SPARCle.

merge to -current.

avoid writing 1 byte beyond the end of the string promlib.c has given us.
instead of forcing a nul byte afterwards, KASSERT() that the final byte
already is a nul.  if there are broken proms... well, we can fix them.

this, plus one more change, allows my SS20 to boot multiuser.

add per ivec event counters

#include <sys/bus.h> instead of <machine/bus.h>.

Update for new pci_devinfo(9) signature.

Use prom_getpropstring().

Make sure prom_getprop is called with the size pointed to by nitem
initialized. (Some of these are more paranoia, but two were actual bugs.)
Print error codes in some panic messages.

Rename PROM_getprop*() => prom_getprop*().

Nuke bcopy/bzero.

change PROM_getprop() from taking a "void **" for the storage, to a
"void *", and do the extra de-reference directly in the function.  this
avoids having to cast dozens of different types to "void **", which sets
of GCC3's strict-aliasing.  testing by martin@

__KERNEL_RCSID()

Avoid strict-alias warnings in gcc 3.3.

DMA, not dma nor Dma.

Sync with HEAD.

Use aprint_normal() for cfprint routines.

Sync with HEAD.

Remove the `flags' argument from bus_intr_establish().

bus_intr_establish() signature change.
The additional `fast trap' argument is ignored in these drivers.
BUS_INTR_ESTABLISH_FASTTRAP and BUS_INTR_ESTABLISH_SOFTINTR are no longer used.

Catch up to -current.

sync kqueue with -current; this includes merge of gehenna-devsw branch,
merge of i386 MP branch, and part of autoconf rototil work

Add trailing ; to CFATTACH_DECL.

Use CFATTACH_DECL().

Declare all cfattach structures const.

catch up with -current on kqueue branch

Catch up to -current.
(CVS: It's not just a program. It's an adventure!)

convert to using <dev/ebus/ebusvar.h> and it's struct member names.

Get PCI working with the new bus_space*.

Sync kqueue branch with -current.

file ebus.c was added on branch nathanw_sa on 2002-04-01 07:43:00 +0000

clean up ebus:
	- kill dead dma code
	- remove icky self->dv_parent casts

audiocs @ ebus doesn't crash anymore, but it doesn't appear to work
yet either...

Catch up with -current.

getprop* -> PROM_getprop*

Change bus_space_mmap() signature to the official one.

Update the kqueue branch to HEAD.

Get rid of spurious OF_getprop().

Sun Blade 100 support (and some psycho fixes from Jason Wright).

update to -current

Don't match ebus nodes not called "ebus" like the ones on hme cards.

PCI overhaul.

Catch up to -current.

fix lint exposed by GCC 3.0 20010604 (prerelease).

correct some comments.  <80 char debug statements.

do not force ebus interrupts to have bit 0x20 set.

Pull up revision 1.17 (requested by martin):
  Fix a bug: ``sc'' is a pointer, so use it correctly.

Sync with head (for UBC+NFS fixes, mostly).

ebus_find_node(): plug memory leak; make debug output meaningfuller.

Sync with HEAD.

Warning police. Mostly useless format warnings. Switch Makefile for
kernel compiles to the warning flags that other ports also use.

Update thorpej_scsipi to -current as of a month ago
A i386 GENERIC kernel compiles without the siop, ahc and bha drivers
(will be updated later). i386 IDE/ATAPI and ncr work, as well as
sparc/esp_sbus. alpha should work as well (untested yet).
siop, ahc and bha will be updated once I've updated the branch to current
-current, as well as machine-dependant code.

ebus sc_is is a pointer now, already.

pullup the contents of -current arch/sparc64.  this gives us significant
ultrasparc PCI support (ultra5, ultra10, AXi, and E250 tested so far),
plus many other small fixes.  netbooting is now supported.

If there is no "interrupt-map" property on the ebus node, assume the
child "interrupt" properties are already in a format suitable for
the parent bus.

Add a `device class' interrupt level argument (from machine/intr.h)
to bus_interrupt_establish().

It's currently only used in sparc64/dev/psycho.c to assign a CPU interrupt
level to devices in PCI slots.

remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>

remove/move more mach vm header files:

	<vm/pglist.h> -> <uvm/uvm_pglist.h>
	<vm/vm_inherit.h> -> <uvm/uvm_inherit.h>
	<vm/vm_kern.h> -> into <uvm/uvm_extern.h>
	<vm/vm_object.h> -> nothing
	<vm/vm_pager.h> -> into <uvm/uvm_pager.h>

also includes a bunch of <vm/vm_page.h> include removals (due to redudancy
with <vm/vm.h>), and a scattering of other similar headers.

Enable interrupts.

Sync w/ netbsd-1-5-base.

ebus_ca needs to specify enough memory to hold an ebus_softc, not a struct device.

ensure an ebus really does exist in ebus_match; fixes spurious attachments with the ebus on a hme pci card.

expand a comment slightly.

whole bunch of changes:
- merge IOMMU DVMA code from sbus/psycho into iommu.c.  this code was
  identical and a few minor inconsistencies had crept in.  this way
  keeps them all in sync.
- with this code gone from psycho, merge the psycho.c and psycho_bus.c
  files.  same with ebus/ebus_bus.c.  delete the _bus.c files.
- add a _ds_boundary member to the dma segment structure, so that later
  dma mappings can find this value.
- set _ds_boundary in machdep.c:_bus_dmamem_alloc().
- kill much dead code.

- auxio cleanup and sbus support.
- make GENERIC64 include GENERIC and set the 3 optoins it needs.  suggested
  by hubert feyrer.
- add a comment that we maybe should use the `bpp' driver, not the lpt, on
  the ebus because the `bpp' driver does DMA already.
- ebus_attach_args got a member renamed

avoid a potential memory leak.

- store the ebus's parent so we can find the IOMMU
- use generic iommu routines in the ebus code (uses the above)
- add some more comments.

be slightly more verbose when attaching ebus devices.

Sync w/ -current.

find ebus device INO values via the "interrupt-map" and "interrupt-map-mask" properties.

avoid uninitalised pointers.

support for the UltraSPARC `Extension Bus' found on the PCI machines.
the bus space/dma code is cloned from the PCI code to do the same thing
which itself was cloned from the sbus bus space/dma code.  the bus dma
code is non-functional at this point.
