 1.44  20-Dec-2023  thorpej Remove unnecessary <sys/malloc.h>.
 1.43  24-Sep-2023  andvar define i variable in for loop.
mesh_msgin() doesn't have one defined in the function scope.

fixes MESH_DEBUG enabled build for macppc.
 1.42  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.41  24-Apr-2021  thorpej branches: 1.41.8;
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?).
 1.40  05-Mar-2021  rin branches: 1.40.2;
Convert to intr_establish_xname().
 1.39  31-Mar-2017  msaitoh branches: 1.39.26;
Remove extra 0x. This bug was added when replacing bitmask_snprintf(9) with
snprintb(3) (in between NetBSD 5 and 6). Old bitmask_snprint(9) didn't add
0x" automatically for hexadecimal value, so old code used it with "0x%s".
 1.38  15-Feb-2017  tsutsui Fix an inverted logic.
 1.37  15-Jul-2016  macallan branches: 1.37.2;
adjust to dbdma changes
 1.36  14-Mar-2014  mrg branches: 1.36.6; 1.36.10;
remove various set-but-unused variables.
 1.35  30-Jun-2011  matt branches: 1.35.2; 1.35.12; 1.35.16;
Modify mapiodev to take a third argument indicating whether the space
should be prefetchable (true) or not (false).
 1.34  26-Sep-2009  tsutsui Make local functions static.
 1.33  26-Sep-2009  tsutsui Replace shutdownhook_establish(9) with pmf_device_register1(9).
Tested on Apus2000.
 1.32  26-Sep-2009  tsutsui Fix a botch on device_t/softc split:
Don't forget to set sc->sc_dev.
 1.31  15-May-2009  tsutsui Split device_t/softc. Tested on Apus2000.
 1.30  14-Mar-2009  dsl ANSIfy another 1261 function definitions.
The only ones left in sys are beyond by sed script!
(or in sys/dist or sys/external)
Mostly they have function pointer parameters.
 1.29  14-Mar-2009  dsl Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)
 1.28  14-Mar-2009  dsl Remove all the __P() from sys (excluding sys/dist)
Diff checked with grep and MK1 eyeball.
i386 and amd64 GENERIC and sys still build.
 1.27  16-Dec-2008  christos branches: 1.27.2;
replace bitmask_snprintf(9) with snprintb(3)
 1.26  17-Oct-2007  garbled branches: 1.26.16; 1.26.20; 1.26.28;
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.
 1.25  29-Mar-2006  thorpej branches: 1.25.18; 1.25.26; 1.25.36; 1.25.38; 1.25.40; 1.25.42;
Use device_cfdata().
 1.24  24-Dec-2005  perry branches: 1.24.4; 1.24.6; 1.24.8; 1.24.10; 1.24.12;
Remove leading __ from __(const|inline|signed|volatile) -- it is obsolete.
 1.23  17-Dec-2005  macallan return SCSI_CHECK in xs->status instead of xs->xs_status
This fixes a whole bunch of weird errors that plague(d) mesh forever, like
- failure to spin up drives automatically
- occasional bogus 'drive offline' messages
- LONG delays when trying to use a ZIP drive

It will probably expose more problems, we'll see.
 1.22  11-Dec-2005  christos merge ktrace-lwp.
 1.21  09-Dec-2004  briggs branches: 1.21.8; 1.21.10;
Several changes from Michael Lorenz. Adapted from PR port-macppc/27680.
1. Reset SCSI bus & MESH on reboot to keep OF happy.
2. Tweak interrupt handler to clear interrupt register again if we get a
CMDDONE interrupt with DMA active and a 0 fifocnt. It's not clear why
this is necessary, but is well documented in some other open source
drivers. This enables synchronous mode to work.
3. Dump a little more information if we do get a timeout.
 1.20  07-Dec-2004  thorpej Use "struct scsipi_command" in internal command structures so that
we have enough space for 16-byte CDBs.
 1.19  15-Jul-2003  lukem __KERNEL_RCSID()
 1.18  03-May-2003  wiz branches: 1.18.2;
DMA, not dma nor Dma.
 1.17  02-Apr-2003  thorpej Use PAGE_SIZE rather than NBPG.
 1.16  02-Oct-2002  thorpej Use CFATTACH_DECL().
 1.15  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.14  05-Apr-2002  bouyer Implement mstohz() as discussed on tech-kern, and use it in SCSI drivers
to convert xs->timeout to callout() parameter.
 1.13  04-Nov-2001  tsutsui Use common macro to check message length.
 1.12  22-Jul-2001  wiz branches: 1.12.4; 1.12.6;
bcopy -> memcpy, bzero -> memset, bcmp -> memcmp.
Reviewed by Matt Thomas, ok'd by Tsubai Masanari.
 1.11  08-Jun-2001  matt branches: 1.11.2;
Make macppc compile by default with -Wall -Wmissing-prototype in addition
to its currently enabled warnings. For the lack of a better place, most
global function prototype wound up in <machine/autoconf.h> unless there
was a better place for them. ofb_* structs renamed to offb_* to avoid
conflict with ofb_softc in <dev/ofw/openfirm.h>
 1.10  26-Apr-2001  tsubai Remove spaces at EOL.
 1.9  25-Apr-2001  bouyer Pull up the thorpej_scsipi branch to main branch.
This is a completely rewritten scsipi_xfer execution engine, and the
associated changes to HBA drivers. Overview of changes & features:
- All xfers are queued in the mid-layer, rather than doing so in an
ad-hoc fashion in individual adapter drivers.
- Adapter/channel resource management in the mid-layer, avoids even trying
to start running an xfer if the adapter/channel doesn't have the resources.
- Better communication between the mid-layer and the adapters.
- Asynchronous event notification mechanism from adapter to mid-layer and
peripherals.
- Better peripheral queue management: freeze/thaw, sorted requeueing during
recovery, etc.
- Clean separation of peripherals, adapters, and adapter channels (no more
scsipi_link).
- Kernel thread for each scsipi_channel makes error recovery much easier
(no more dealing with interrupt context when recovering from an error).
- Mid-layer support for tagged queueing: commands can have the tag type
set explicitly, tag IDs are allocated in the mid-layer (thus eliminating
the need to use buggy tag ID allocation schemes in many adapter drivers).
- support for QUEUE FULL and CHECK CONDITION status in mid-layer; the command
will be requeued, or a REQUEST SENSE will be sent as appropriate.

 1.8  24-Dec-2000  wiz branches: 1.8.2;
Honour SCSI command timeout -- fixes problems with SCSI commands that take
longer than 10s and were falling into a timeout, e.g. fixating.
 1.7  31-Oct-2000  tsubai Match "chrp,mesh0".
 1.6  23-Oct-2000  tsubai Fix Conner CFP1080 problem (pr 7612) and add debugging messages.
 1.5  29-Jun-2000  mrg remove include of <vm/vm.h>. <vm/vm.h> -> <uvm/uvm_extern.h>
 1.4  23-Mar-2000  thorpej branches: 1.4.4;
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.
 1.3  28-Dec-1999  tsubai Remove two panic conditions.
XXX untested.
 1.2  30-Sep-1999  thorpej branches: 1.2.2;

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.

Follow the merge of pmap.c on i386 and amd64 and move
pmap_init_tmp_pgtbl into arch/x86/x86/pmap.c. Modify the ACPI wakeup
code to restore CR4 before jumping back into kernel space as the large
page option might cover that.
