Keyword substitution: kv
Default branch: MAIN

Convert the Alpha port's bus_space back-end to manage address space
with vmem(9) arenas (using statically-allocated private boundary tags
for very early-in-boot) rather than extent(9).

As a side-effect, there's arguments to some initialization functions
that are no longer required, so garbage-collect those, update all the
call sites.

Merge thorpej-cfargs2.

Adapt to CFARGS().

On LCA45 systems, look at the memory controller's Bcache configuration
to initialize uvmexp.ncolors rather than hard-coding a value per model
(some models can have more than one configuration).

Remove unnecessary #include <sys/malloc.h>

Don't use a bunch of switch() statements in the core logic drivers to select
the PCI interrupt initialization routine.  Instead, register said routines
by systype in a link set, and look them up and invoke them in a new function
alpha_pci_intr_init().

Sprinkle some static.

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?).

Convert config_found_ia() call sites where the device only carries
a single interface attribute to bare config_found() calls.

PCI_FLAGS_IO_ENABLED and PCI_FLAGS_MEM_ENABLED changed their functional
role in NetBSD (drivers are no longer supposed to write these to
pa_flags) without changing name.  Correct that.

Rename PCI_FLAGS_IO_ENABLED to PCI_FLAGS_IO_OKAY and
PCI_FLAGS_MEM_ENABLED to PCI_FLAGS_MEM_OKAY, thus making their names
consistent with the other PCI flags and poisoning 3rd-party driver
sources that use the flags in the old bad way.

This patch produces no binary changes in this set of PCI kernels when
they are compiled w/o 'options DIAGNOSTIC' and w/ -V MKREPRO=yes:

Phase out the use of a string as first "attach args" member to control
which bustype should be attached with a specific call to config_found()
(from a "mainbus" or a bus bridge).
Do it for isa/eisa/mca and pci/agp for now. These buses all attach to
an mi interface attribute "isabus", "eisabus" etc., and the autoconf
framework now allows to specify an interface attribute on config_found()
and config_search(), which limits the search of matching config data
to these which attach to that specific attribute.
So we basically have to call config_found_ia(..., "foobus", ...) where
such a bus is attached.
As a consequence, where a "mainbus" or alike also attaches other
devices (eg CPUs) which do not attach to a specific attribute yet,
we need at least pass an attribute name (different from "foobus") so
that the foo bus is not found at these places. This made some minor
changes necessary which are not obviously related to the mentioned buses.

Handle 64bit DMA addresses on PCI for platforms that can (currently only
enabled on amd64). Add a dmat64 field to various PCI attach structures,
and pass it down where needed. Implement a simple new function called
pci_dma64_available(pa) to test if 64bit DMA addresses may be used.
This returns 1 iff _PCI_HAVE_DMA64 is defined in <machine/pci_machdep.h>,
and there is more than 4G of memory.

* Add "pcitag_t *pba_bridgetag" to pci_attach_args.  This is set to
  NULL for root PCI busses.  For busses behind a bridge, it points to
  a persistent copy of the bridge's pcitag_t.  This can be very useful
  for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
  uses OFW device nodes to enumerate the bus.  When a PCI bus that is
  behind a bridge is attached, pci_attach_hook() allocates a new PCI
  chipset tag for the new bus and sets it's "curnode" to the OFW node
  of the bridge.  This is used as a starting point when enumerating
  that bus.  Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.

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.

- Add a bus space method for getting the translation for a window.
- Add sysarch methods for "get bus window count", "get bus window",

These are a hack, but they're what's necessary in order to make
XFree86 work in its current state.

be more consistent about use of 'cputype'.  e.g. it's in a header, don't
bother 'externing' it everywhere!

Take a stab at EB66 support.  An EB66 is basically an EB64+ with a
21066 LCA instead of a 21064 + APECS.

Oops, forgot option header.

Very preliminary support for the Tadpole/DEC AlphaBook.  These are basically
AXPpci33 machines + power management and a Cirrus PCI-PCMCIA controller.

There is currently no support for the power management facilities, and
the PCI-PCMCIA controller driver needs some work, but this should boot
and run from disk.

Don't call *_dma_init() twice; there's no need to.  Just do it in *attach().

Garbage-collect the old confargs stuff that was used in the Early Days.
It isn't really appropriate anymore.  Replace it with a real mainbus
attach args structure.

Don't assume that we'll be using direct-mapped DMA for PCI.

Adjust for config changes.

Update marc-pcmcia branch from trunk.

Fix a typo.

Pull in DEC_AXPPCI_33 option.

Nuke the idea of <machine/options.h>.  It completely defeats the purpose
of fine-grain option dependencies.

Fix oversight in a previous commit.

Treat bus space tags more like pci chipset tags and bus dma tags: allocate
them statically within a chipset's state structure, and pass them to
the *_bus_{io,mem}_init() functions.

syng thorpej-bus-dma changes with alpha-nwscons branch

Pull thorpej-bus-dma branch into mainline.

sync the nwscons branch up with yesterday's version of the trunk.
Lots of conflicts/changes because of the RCS Id format changes.
Also, a few cleanups and corrections.

- Garbage-collect all DMA-related initialization, calling a separate
  *_dma_init() function instead.
- Pass the appropriate bus dma tag to children.

pass memory- and i/o-enabled flags down via the PCI bus and device attach
arguments, so that a device can tell if its memory and I/O spaces are
enabled.  The flags are cleared, depending on the contents of devices CSR
registers, in the machine-independent PCI bus code.

by default, provide RCS IDs for NetBSD/alpha kernel files in kernel binaries.
This can be disabled (to save a bit of space) with the NO_KERNEL_RCSIDS
options, which is present but commented out in the ALPHA config file.
In ELF-format kernels, these strings are present in the kernel binary but
are not loaded into memory.  (In ECOFF-format kernels, there's no easy way
to keep them from being loaded, so they _are_ loaded into memory.)

clean up NetBSD RCS ID strings, include machine/options.h

clean up some #ifdefs

sync __BROKEN_INDIRECT_CONFIG removal with trunk.

remove all traces of __BROKEN_INDIRECT_CONFIG (except in shared drivers)

mostly sync with changes on the trunk

update these so they compile whether or not __BROKEN_INDIRECT_CONFIG
is defined.

update for new extent management code.  Most importantly, we can't call
the chipset space init functions multiple times, since that would clobber
extent allocations made between the two calls.  Also, deal with the
fact that the APECS and LCA no longer shared common chipset functions.

clean up some spacing in switch statements

update for new bus.h macros.  bus_io_* and bus_mem_* integrated into
single bus_space_* framework.  Unfortunately, bus_space_{read,write}_*
operations still imply barriers.  That will change soon.

backout previous kprintf change

printf -> kprintf, sprintf -> ksprintf

change cfprint_t type definition to take a const char *, rather than
a char *, because that's what was really intended, and because
if the print function modifies the string, various things could become
unhappy (so the string should _not_ be modified).

some cleanup for -Wall

clean and update for new defintions, prototypes, etc.

Corrections from hardware manual, from Trevor Mendez <tmendez@bbn.com>.
Adds comments and sets IOC_CONF correctly (it's write-only!).

clean up copyrights and RCS IDs

partially update for new ISA/EISA/PCI and 'bus' interfaces.  not yet
complete, or tested.

New device attachment scheme:

	- split softc size and match/attach out from cfdriver into
	  a new struct cfattach.

	- new "attach" directive for files.*.  May specify the name of
	  the cfattach structure, so that devices may be easily attached
	  to parents with different autoconfiguration semantics.

wholesale update from my NetBSD/Alpha source tree.  Includes:
	Support for AXPpci CPUs,
	Support for AlphaStation 600 CPUs,
	new boot block structure, which requires an 'installboot'
	    program and works a lot like the NetBSD/sparc boot blocks.
