 1.53 07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.52 24-Apr-2021  thorpej branches: 1.52.8;
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?).
 1.51 18-Nov-2020  thorpej branches: 1.51.2;
malloc(9) -> kmem(9)
 1.50 10-Nov-2019  chs branches: 1.50.8;
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.
 1.49 27-Oct-2012  chs branches: 1.49.38;
split device_t/softc for all remaining drivers.
replace "struct device *" with "device_t".
use device_xname(), device_unit(), etc.
 1.48 06-Mar-2011  tsutsui branches: 1.48.4; 1.48.14;
Remove trailing spaces.
 1.47 16-Dec-2009  matt branches: 1.47.4; 1.47.6;
Fix various build with the 32bit mips ports after the mips64 merge.
 1.46 27-Nov-2009  rmind - Use uvm_lwp_setuarea() instead of directly setting address to lwp_t::l_addr.
- Replace most remaining uses of l_addr with uvm_lwp_getuarea() or lwp_getpcb().
- Amend assembly in ports where it accesses PCB via struct user.
- Rename L_ADDR to L_PCB in few places. Reduce sys/user.h inclusions.
 1.45 19-Aug-2009  dyoung Define, and hook into the isa_chipset_tag_t, isabr_detach_hook().

 1.42 14-Mar-2008  tsutsui Fix spl(9) botch in cpu_intr() on arc:
Don't enable unhandled interrupts before all interrupts are processed,
and also change all interrupt handlers to return processed MIPS_INT_MASK
values, rather than masked values of them.
 1.41 03-Dec-2007  ad branches: 1.41.10; 1.41.14;
Interrupt handling changes, in discussion since February:

- Reduce available SPL levels for hardware devices to none, vm, sched, high.
- Acquire kernel_lock only for interrupts at IPL_VM.
- Implement threaded soft interrupts.
 1.40 17-Oct-2007  garbled branches: 1.40.2;
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.
 1.39 11-Jul-2007  he branches: 1.39.8; 1.39.10;
Adapt to the new signature of callout_init().
 1.38 09-Jul-2007  ad Merge some of the less invasive changes from the vmlocking branch:

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements
 1.37 04-Mar-2007  christos branches: 1.37.2; 1.37.4; 1.37.10;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.
 1.36 02-Jul-2006  tsutsui branches: 1.36.10;
Use register macro defined in <dev/ic/i8259reg.h>.
 1.35 25-Jun-2006  tsutsui Remove unused struct abus stuff.
 1.34 13-Jun-2006  tsutsui branches: 1.34.2;
Before calling the handler of timer at isa for hardclock(9),
clear MIPS_SR_INT_IE in struct clockframe status to prevent
unintentional spllowersoftclock(9) in hardclock(9).
This may be required because current CLKF_BASEPRI() implementation
of NetBSD/arc doesn't check ICU_MASK and all ISA devices share
the same MIPS CPU INT2 interrupt.

BTW, has anyone tried IPL_ICU_MASK on any mips ports?
 1.33 12-Jun-2006  tsutsui Account ISA interrupts by evcnt(9)
 1.32 12-Jun-2006  tsutsui - rename struct intrhand -> struct isa_intrhand
- remove unused ih_what member
 1.31 11-Jun-2006  tsutsui Check whether the specified interrupt handler is valid before referring it.
 1.30 15-Nov-2005  tsutsui branches: 1.30.4; 1.30.8; 1.30.14;
Explicitly enable interrupts before softintr is handled as noted
in the TODO file. At least this fixes "sn0: receive buffers exhausted"
messages on my NEC-JC94.

XXX: does anyone know what "Dont reenable" comment means, which was
XXX: there since initial import of pica (not arc).
 1.29 30-Oct-2005  tsutsui branches: 1.29.2;
Use mips3_cp0_count_read() for precise microtime(9).

XXX microtime(9) function should be moved from machdep.c to timer.c?
 1.28 22-Jan-2005  tsutsui branches: 1.28.8; 1.28.10;
Make all intr_mask value types uint32_t rather than int, u_int,
or unsigned etc.
 1.27 22-Jan-2005  tsutsui - remove __P()
- use ANSI function decls
- u_intNN_t -> uintNN_t
- some KNF
 1.26 30-Aug-2004  drochner branches: 1.26.4;
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.
 1.25 07-Aug-2003  agc Move UCB-licensed code from 4-clause to 3-clause licence.

 1.9 04-Jun-2000  cgd Implement the more flexiable `evcnt' interface as discussed (briefly) on
tech-kern and now documented in evcnt(9).
 1.8 23-Mar-2000  thorpej branches: 1.8.2;
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.

* include <mips/cpuregs.h>, not the old Sprite-derived <machine/machConst.h>.
machConst.h is deprecated.
* dk_establish() must return void, not int.

* Add a "pnpnames" and a linked list of "pnpcompatnames" to the
isa_attach_args. If either of these members are non-NULL,
direct configuration of the bus is being performed. Add an
ISA_DIRECT_CONFIG() macro to test for this.
* Drivers are not allowed to modify the isa_attach_args unless
direct configuration is not being performed and the probe fucntion
is returning success.
* Adapt device drivers -- currently, all driver probe routines return
"no match" if ISA_DIRECT_CONFIG() evaluates to true.

A i386 GENERIC kernel compiles without the siop, ahc and bha drivers

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.

Remove duplicate #includes, patch contributed in private mail
by Slava Semushin <slava.semushin@gmail.com>.

To verify that no nasty side effects of duplicate includes (or their
removal) have an effect here, I've compiled an i386/ALL kernel with
and without the patch, and the only difference in the resulting .o
files was in shifted line numbers in some assert() calls.
The comparison of the .o files was based on the output of "objdump -D".

Thanks to martin@ for the input on testing.
