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().

Sync with HEAD.

Liberally sprinkle static around to get more symbols out of the
global namespace.  A small bit of const poisoning in the TC code.

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?).

config_found_ia() -> config_found() w/ CFARG_IATTR.

Mechanical conversion of config_found_sm_loc() -> config_found().
CFARG_IATTR usage needs to be audited.

isa_detach_hook() needs two arguments, the first an isa_chipset_tag_t.

Define isa_dmadestroy and isa_detach_hook.  Hook up a couple of
isa_detach_hook implementations.

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.

Avoid NULL pointer dereference in MD device_register() function.
Fixes a part of PR port-alpha/36628.
Backout changes on lpt_jensenio.c rev 1.2.
lpt at jensenio doesn't seem to have a specific interrupt vector
but uses a normal EISA interrupt.
Fixes another part of PR port-alpha/36628 and PR port-alpha/20386.
More fixes for Jensen, reported and tested by Christoph Franzen
in PR port-alpha/36628:
- make jensenio_eisa_maxslots() return 8 (instead of 16) since
  EISA config for slot 8-15 on jensen could return invalid values
- pass eisa_chipset_tag_t to eisa_init() and check eisa_maxslots()
  on probing EISA config space
- pass M_ZERO to malloc(9) and make sure malloc(9) doesn't fail
- fix typo in a debug printf, add more debug printfs, and
  use #ifdef EISA_DEBUG to enable them
- cast uint8_t value to uint32_t before shift more than 8 bits
- check buffer region on reading compressed data from EISA config space
Check a correct value on a sanity check in jensenio_eisa_intr_map().
Fixes yet another bug on Jensen found on tracking PR port-alpha/36628.

merge ktrace-lwp.

Sync with HEAD. Here we go again...

kill some more simple submatch() functions, use config_stdsubmatch()

replace the "locdesc_t" structure carrying the number of locators
explicitely by a plain integer array
the length in now known to all relevant parties, so this avoids
duplication of information, and we can allocate that thing in
drivers without hacks

Fix the sync with head I botched.

include "locators.h" explicitely (don't rely on isavar.h doing so)

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.

Use aprint_normal() for cfprint routines.

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

Use CFATTACH_DECL().

Declare all cfattach structures const.

Introduce a new routine, config_match(), which invokes the
cfattach->ca_match function in behalf of the caller.  Use it
rather than invoking cfattach->ca_match directly.

Rather than referencing the cfdriver directly in the cfdata entries,
instead use a string naming the driver.  The cfdriver is then looked
up in a list which is built at run-time.

update to -current

file jensenio.c was added on branch nathanw_sa on 2002-10-18 02:34:15 +0000

Rework the interrupt code, shaving some cycles off in the process.
Rather than an "iointr" routine that decomposes a vector into an
IRQ, we maintain a vector table directly, hooking up each "iointr"
routine at the correct vector.  This also allows us to hook device
interrupts up to specific vectors (c.f. Jensen).

We can shave even more cycles off, here, and I will, but it requires
some changes to the alpha_shared_intr stuff.

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.
