Don't frob MCR_IEN bit if on a 425e. Problem initially reported
by Christoph Badura:

It looks to me like the 425e uses reverse polarity of the MCR_IEN bit with
respect to the other 4xx models. That could be because it doesn't have
an inverter wired behind the IEN(OUT2) output of the UART.

Fix is inspired by change in OpenBSD. Serial console input is
confirmed working on 425e by Thilo Manske.

Attach apci console as an intio device, not a dio device.
Fixes console attach on 425e noted by Thilo Manske.

Convert ioctl code to use EPASSTHROUGH instead of -1 or ENOTTY for
indicating an unhandled "command". ERESTART is -1, which can lead to

Add a kernel driver for the APCI 8250-like UARTs that live in the
Frodo ASIC, originally contributed by Mike Smith
<mike@pressed.spam.frisbee.net.au>, but reworked by me to:
- Essentially duplicate the dca driver, modifiying where necessary
to work with the APCI.
- Deal with the different Frodo autoconfiguration model.
- Don't attach a tty to the 0th UART - it's not really useful for much
more than the Domain keyboard.
- Added a routine to check for the existence of a DCA at select code 9.
On most models, the 1'th UART is mapped to select code 9 by the PROM,
and on these models, we do _NOT_ want to attach the device as an APCI.
However, on the 425e, this mapping does not take place, so we attach
as an APCI. The 2'th and 3'th UARTs always get tty instances.
- Add console support which will only be invoked on the 425e (i.e. check
for DCA at 9, and defer console to it if it exists).

Move apcireg.h and dcareg.h to stand/common since they are no longer used
by kernel.

Several years ago, the interrupt priority levels for devices were "flattened"
such that IPL_BIO, IPL_NET, and IPL_TTY (logical interrupt priority levels)
became aliases of IPL_VM (the logical interrupt priority level above which
memory allocation is not allowed). Unfortuantely, this meant that any
use of these logical interrupt priority levels to differentiate between
different interrupt service routines at the same auto-vectored interrupt
level was pointless... "when everyone is special, no one is".

Before this flattening happened, these distinct logical interrupt priority
levels levels were dynamically mapped to physical auto-vectored interrupt
levels based on which types of devices registered themselves at which auto-
vectored level. Now, splbio(), splnet(), etc. are all equivalent to splvm(),
which effectively blocks all device interrupts.

Switch to using the ISRPRI_* values provided by the common m68k interrupt
dispatch code, which allows interrupt handlers for devices that are more
latency-sensitive to be sorted earlier in the list of handlers at a given
auto-vectored interrupt level, as was originally intended.

- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency

- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.

it can be called before UVM and related initializations are complete.

Several years ago, the interrupt priority levels for devices were "flattened"
such that IPL_BIO, IPL_NET, and IPL_TTY (logical interrupt priority levels)
became aliases of IPL_VM (the logical interrupt priority level above which
memory allocation is not allowed). Unfortuantely, this meant that any
use of these logical interrupt priority levels to differentiate between
different interrupt service routines at the same auto-vectored interrupt
level was pointless... "when everyone is special, no one is".

Before this flattening happened, these distinct logical interrupt priority
levels levels were dynamically mapped to physical auto-vectored interrupt
levels based on which types of devices registered themselves at which auto-
vectored level. Now, splbio(), splnet(), etc. are all equivalent to splvm(),
which effectively blocks all device interrupts.

Switch to using the ISRPRI_* values provided by the common m68k interrupt
dispatch code, which allows interrupt handlers for devices that are more
latency-sensitive to be sorted earlier in the list of handlers at a given
auto-vectored interrupt level, as was originally intended.

Fix from Steve Peurifoy in PR#18849:

"Occasionally a blocking open of dcm port 0 will hang in ttyopen()
waiting for carrier detect to be asserted when it's already
present.

The problem is that dcmmint() will return before updating the
value of sc->sc_mcndlast if the device is not open. If carrier
detect drops after the device is closed, sc->sc_mcndlast will
no longer correctly represent the "previous" state of the
signals when the next transition of carrier detect occurs.
A subsequent blocking open will wait forever for an event
which has in fact taken place."

Garbage-collect all old-style autoconfiguration support; it is no
longer supported. The hp300 port uses new config now.

Snapshot of new config for NetBSD/hp300. This isn't quite finished yet.
We're about 75% there. SCSI and HP-IB are not yet supported in a new
config kernel; some autoconfiguration hackery has to be done there, yet.
These changes are enough to network boot a diskless kernel.

New config glue is enabled with the "NEWCONFIG" kernel option. If that
option is not present, an old config kernel will be built. Any kernel
configured with config(8) will automatically pick up the NEWCONFIG
option from std.hp300.

Fix computation of the appropriate auto-vector interrupt level to use
for the DMA controller by tracking all of the DIO devices that have
"ISRPRI_BIO" interrupt handlers, and finding the highest auto-vector
level among them and informing the DMA controller.

Previously, in a post-flattening world, the DMA controller was always
told to interrupt at lev5, which is fine I guess although definitely not
ideal, but would not work on aaaancient HP320 Rev A DMA boards. To that
effect, print a warning if a Rev B DMA board ends up at ipl != 3 (we can't
differentiate between a Rev A and a Rev B board).

Switch hp300 over to the common interrupt dispatch code.

XXX There are still some things to fix up here, but it's no worse
than it was before (the problems date back to when we flattened
the device interrupt levels into IPL_VM).

Merge thorpej-cfargs2.

branches: 1.40.8;
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?).

Clean-up the DIO bus. Includes two main changes:

The hack to allow the nhpib driver to support internal and DIO
controllers appears to be a leftover from 4.3BD where it was not

If sysflags tells us we have an internal HP-IB interface, don't bother
reading the DIO device ID at select code 7, but rather hard-wire the ID
to the IHPIB ID. This prevents us reading what might look like a valid
ID to another device when IHPIB is present. (IHPIB doesn't always return
a correct device ID, grumble.)

Fix topcat(4) problems on some models that cause garbages on screen.

- Make sure that windowmove (hardware BITBLT) ops complete by checking
tc_busywait() before calling putchar functions by MI rasops(9).
It looks CPU accesses against VRAM during windowmove (copy, erase,
and cursor) ops causes unexpected garbages at least on 98543 on HP360,
98547 on HP370, and also on 98543 on 040 HP380 (but not on 98549).

- Handle 'sparse VRAM' on 98543 (and probably 98542) properly:
- Prepare and use own topcat_putchar1_4() function for sparse VRAM.
- Pass proper 'VRAM width' rather than actuall font width to all
windowmove (copycols, erasecols, copyrows, eraserows, and do_cursor)
operation functions.

Now all topcat(4) consoles on 98543 on HP360/HP380 and 98547 on HP370
work fine, and no visible regression on 98549 on HP380 and 98544 on HP360.

Move a check of topcat(4) specific fb width quirks to topcat.c.

Also add a comment that it looks these 1 bpp and 4 bpp boards have
VRAM with sparse address layout and we have to handle
512 pixels per line with 1024 bytes per line.

Fix another fatal typo that prevents dma(4) interrupts.

Fix computation of the appropriate auto-vector interrupt level to use
for the DMA controller by tracking all of the DIO devices that have
"ISRPRI_BIO" interrupt handlers, and finding the highest auto-vector

Previously, in a post-flattening world, the DMA controller was always
told to interrupt at lev5, which is fine I guess although definitely not
ideal, but would not work on aaaancient HP320 Rev A DMA boards. To that
effect, print a warning if a Rev B DMA board ends up at ipl != 3 (we can't
differentiate between a Rev A and a Rev B board).

Several years ago, the interrupt priority levels for devices were "flattened"
such that IPL_BIO, IPL_NET, and IPL_TTY (logical interrupt priority levels)
became aliases of IPL_VM (the logical interrupt priority level above which
memory allocation is not allowed). Unfortuantely, this meant that any
use of these logical interrupt priority levels to differentiate between
different interrupt service routines at the same auto-vectored interrupt
level was pointless... "when everyone is special, no one is".

Before this flattening happened, these distinct logical interrupt priority
levels levels were dynamically mapped to physical auto-vectored interrupt
levels based on which types of devices registered themselves at which auto-
vectored level. Now, splbio(), splnet(), etc. are all equivalent to splvm(),
which effectively blocks all device interrupts.

Switch to using the ISRPRI_* values provided by the common m68k interrupt
dispatch code, which allows interrupt handlers for devices that are more
latency-sensitive to be sorted earlier in the list of handlers at a given
auto-vectored interrupt level, as was originally intended.

TAB/space cleanup.

fix PR 6724 - convert m68k options to defflag's. this means that
M680[12346] are now available from opt_m68k_arch.h. FPSP meantioned
in the PR has already been fixed, and i could not find any more.

Don't recompute an ipl level for IPL_VM during or after cpu_configure(9)
and use a static and possible highest ipl value (ipl 5) for IPL_VM
so that we can put ipl2psl_table[] conversion into makeiplcookie(9),
which could be called before cpu_configure(9).

Fixes "panic: sbappendaddr" on NFS load.

Unify splraiseipl(9) implementation among m68k ports as per
suggestion from isaki@ on port-m68k.

For hp300:
- use ipl2psl_table[] for makeiplcookie() conversion
- use uint16_t for ipl2psl_table[]

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Use PAGE_SIZE rather than NBPG.

Make the DMA controller a separate device attached to intio. Intio
devices can use the DMA controller too.

merge the 12 copies of vm_machdep.c on the m68k platforms.
clean up some other stuff along the way, including:
- use m68k/cacheops.*, remove duplicates from cpu.h.
- centralize a few declarations in (all the copies of) cpu.h.
- define M68K_VAC on platforms which have a VAC.
- switch the sun platforms to the (now common) proc_trampoline().
- do the phys_map thang on the sun platforms too, no reason not to.

Add RCSIDs.

New callout mechanism with two major improvements over the old
timeout()/untimeout() API:
- Clients supply callout handle storage, thus eliminating problems of
resource allocation.
- Insertion and removal of callouts is constant time, important as
this facility is used quite a lot in the kernel.

The old timeout()/untimeout() API has been removed from the kernel.
