Enable Personal IRIS 4D/20 and 4D/25 support:
- Adapt int(4) to handle the INT1 chip
- Move generic rtc clocks out of hpc/ and into dev/
- Handle the very strangely wired eeprom and other bits in arcemu
- Sprinkle MACH_SGI_IP6 as necessary
- Enable IP6/IP10 devices in GENERIC32_IP12. Yes, the naming is poor but
there's no winning with kernel/hw compatibility on sgimips...

Tested on my 4D/25. Doesn't (appear to) break macallan@'s IP22.

Also, don't use the cursor sprite as text cursor - it's not worth the pain and
the sprite doesn't have an invert-background plane either so the cursor wasn't

Instead blit the cursor using the appropriate ROPs. This way we get rid of the

Provide a pseudo-pci bus for the following PCI ethernet boards, which live

- Set Engineering GIO Fast Ethernet (TI ThunderLAN)
- Phobos G100 (DEC 21140?)
- Phobos G130 (DEC 21143)
- Phobos G160 (DEC 21143)

All boards present the chipsets' pci configuration registers at some
defined offset in their slots' address space as well as device registers.
We simply allow the MI pci subsystem to attach the devices.

This has been tested with a G130 board (DEC 21143) and works well on IP20
and IP24. The Set Engineering board attaches, works fine when receiving and
lightly transmitting, but chokes for unknown reasons on heavy transmits.

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?).

Support the sq(4) interface on the Challenge S's IOPLUS mezzanine. This
requires us to configure the IOPLUS to use the appropriate DMA channel,

was formerly being configured properly by the PROM. Use the same values,
which appear to work fine.

Also, extend the gio_arb_config interface as needed.

NB: We're currently setting the IOPLUS board to long burst, but it may be
better to use realtime. This will require some experimentation.

IP12 (and perhaps other systems) appear to be buggy and incapable of
reliably supporting badaddr(). False negatives appear to occur
approximately 1.8 percent of the time, although neither false positives
nor consecutive false negatives occur. We take advantage of the latter
property and always use a wrapper that makes multiple checks.

My IP12 no longer sees occasional ghost devices and related panics during
boot.

Rework GIO probing a bit.

Devices present on the GIO bus needn't always provide a Product
Indentification Word, even if their address space is the same as the
address space of a slot. Separate the handling of probing for slot-based
devices and graphics devices, matching the latter first, and precluding
addresses probed for the former when a graphics device is known to exist
in a slot's space.

Indigo and Indigo2 machines have only one shared interrupt for the two
GIO slots. This differs from Indy, which has an interrupt per slot, neither
of which is the same as on the other two machines.

This lets my Phobos G160 run in both slots in my Indigo2 and my E++ adapter
works in both slots in my Indigo.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int. The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER! Some subsystems have

#define min(a, b) ((a) < (b) ? (a) : (b))
#define max(a, b) ((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX. Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate. But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all. (Who knows, maybe in some cases integer
truncation is actually intended!)

No need to have two pre-defined screen types - just adapt to whatever video
mode we find. Also, redraw screen when X exits.
TODO: find out why characters are drawn upside down, for some bizarre reason
this happens right after exiting X but the last line is normal.

Don't bother drawing a cursor until wsdisplay attaches. This works around
the deadlock I've seen with the previous version.
While there do some KNF policing.

Become a good vcons citizen.
Also, don't use the cursor sprite as text cursor - it's not worth the pain and
the sprite doesn't have an invert-background plane either so the cursor wasn't
transparent.
Instead blit the cursor using the appropriate ROPs. This way we get rid of the
cursor misplacement problem as well.
While there also use device_t.
TODO: arbitrary font sizes, cleanup, support for mapping all blitter registers
so we can use them from X.

A bunch of bugfixes:
- set blitter direction appropriately so scrolling downwards works now
- remove a bunch of false +1 so we only copy/erase what we really need to
- slightly change the logic for the cursor sprite offset so it works on this
Indy ( I think what matters is VC2 revision 0 )

Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.9.2;
IP12 (and perhaps other systems) appear to be buggy and incapable of
reliably supporting badaddr(). False negatives appear to occur
approximately 1.8 percent of the time, although neither false positives
nor consecutive false negatives occur. We take advantage of the latter
property and always use a wrapper that makes multiple checks.

My IP12 no longer sees occasional ghost devices and related panics during
boot.

Do not rely on the Product ID Word to be 0x04 since there is no such
thing for graphics options. Since we're removing this, ensure that we can
read the probe registers before proceeding.

Add an extra cookie to the ioctl and mmap wsdisplay accessops that points
to the screen on which they are being called. The driver cannot guess
this by itself but it is needed to implement, at least, the getwschar and
putwschar functions in the correct place. There are no functional changes
yet.

More newport driver tweaks:

* detect and store vc2 revision. This is (likely) the important factor in
determining the proper cursor offset, so add a bit of logic that does the
right thing on my revision 0 vc2. This will have to be determined
empirically, revision by revision.
* take a stab at detecting framebuffer depth. SGI does it quite differently,
but their algorithm doesn't work, so we'll do it along the same lines as
linux.
* implement newport_mmap() for use by X. The necessary xsrc commits have been
made (with the notable exception of the config/cf changes, which probably
shouldn't go in until 4.4.0 has been imported).

Remove unused dc_screens from the softc, the driver does not support multiple
screens.

Slight modifications to newport driver:

* Add resolution and depth variables to softc (for use in X driver, although
depth detection is currently problematic),
* Store more information about various chip revisions,
* Implement ioctls to help the X driver detect device presence and geometry.

Correctly read the board revision.

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?).

Overhaul the interface to pci_configure_bus():
- Don't expose how PCI bus configuration resource management is implemented.
Provide a new resource provider API:

==> pciconf_resource_init() -- Initialize a PCI configuration resources
container.
==> pciconf_resource_add() -- Add a PCI configuration resource to the
container (I/O, MEM, or prefetchable MEM). Multiple resources of
each type may be added.
==> pciconf_resource_fini() -- Tear down the PCI configurtation resources
container once the bus has been configured.

This is much easier to use than the previous method of providing an
extent map for each kind of resource, and works better for e.g. ACPI
platforms that provide potentially multiple PCI resources in tables
provided by firmware.

- Re-implement PCI configuration resource management using vmem arenas,
rather than extent maps.

replace EX_NOWAIT with EX_WAITOK in device attach methods.
remove checks for failures that can no longer occur.

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

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:

Provide a pseudo-pci bus for the following PCI ethernet boards, which live
behind custom PCI<->GIO bridges:
- Set Engineering GIO Fast Ethernet (TI ThunderLAN)
- Phobos G100 (DEC 21140?)
- Phobos G130 (DEC 21143)
- Phobos G160 (DEC 21143)

All boards present the chipsets' pci configuration registers at some
defined offset in their slots' address space as well as device registers.
We simply allow the MI pci subsystem to attach the devices.

This has been tested with a G130 board (DEC 21143) and works well on IP20
and IP24. The Set Engineering board attaches, works fine when receiving and
lightly transmitting, but chokes for unknown reasons on heavy transmits.
The tl(4) driver may need some fixing.
