 1.50  25-Sep-2022  thorpej Remove unnecessary include of <sys/malloc.h>.
 1.49  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.48  24-Apr-2021  thorpej branches: 1.48.8;
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?).
 1.47  05-Mar-2019  msaitoh branches: 1.47.14;
Catch up with MI pci changes to fix compile error.
 1.46  01-Mar-2019  msaitoh - Almost all ppbreg.h's definitions are also in pcireg.h. Remove duplicated
definitions from ppbreg.h and move some definitions from ppbreg.h to
pcireg.h.
- Change fast back-to-back "capable" to "enable" in pci_subr.c.
- Print Primary Discard Timer, Secondary Discard Timer, Discard Timer Status
and Discard Timer SERR# Enable bit in pci_subr.c.
- PCI_BRIDGE_PREFETCHBASE32_REG and PCI_BRIDGE_PREFETCHLIMIT32_REG are
"upper" 32bit registers, rename to *UP32_REG to avoid confusion.
- Use macro.
 1.45  01-Jun-2017  chs branches: 1.45.10;
remove checks for failure after memory allocation calls that cannot fail:

kmem_alloc() with KM_SLEEP
kmem_zalloc() with KM_SLEEP
percpu_alloc()
pserialize_create()
psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.
 1.44  13-Apr-2015  riastradh Convert sys/dev to use <sys/rndsource.h>.
 1.43  17-Oct-2014  uebayasi branches: 1.43.2;
Fix i386 CARDBUS build.
 1.42  02-Feb-2012  tls branches: 1.42.6;
Entropy-pool implementation move and cleanup.

1) Move core entropy-pool code and source/sink/sample management code
to sys/kern from sys/dev.

2) Remove use of NRND as test for presence of entropy-pool code throughout
source tree.

3) Remove use of RND_ENABLED in device drivers as microoptimization to
avoid expensive operations on disabled entropy sources; make the
rnd_add calls do this directly so all callers benefit.

4) Fix bug in recent rnd_add_data()/rnd_add_uint32() changes that might
have lead to slight entropy overestimation for some sources.

5) Add new source types for environmental sensors, power sensors, VM
system events, and skew between clocks, with a sample implementation
for each.

ok releng to go in before the branch due to the difficulty of later
pullup (widespread #ifdef removal and moved files). Tested with release
builds on amd64 and evbarm and live testing on amd64.
 1.41  01-Aug-2011  drochner branches: 1.41.2; 1.41.6;
remove some bloat:
-cardbus doesn't use multiple interrupt lines like PCI, and it doesn't
use machanisms like interrupt line register and swizzling -- no need
to carry around dummy information, this is all dealt with by the
bridge
(I'm asking myself how "rbus_ppb" can work -- a bridge attached to
cardbus just can't work like a normal PCI bridge as far as interrupts
are concerned. I thing that should be a hardware specific driver
because behavior is not covered by a standard.)
-cardbus always uses 3.3V -- no need for a variable to keep track
of the voltage
 1.40  17-May-2011  dyoung 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:

 1.39  05-Mar-2010  dyoung branches: 1.39.2; 1.39.4;
Remove dead code (it is commented out).

Delete the detach routine, it's obviously not finished.
 1.38  04-Mar-2010  dyoung It turns out that ppb at cardbus was not even in ALL. It has probably
not been compiled in a very long time. With some minor changes, it was
possible to make it compile:

Use kmem_zalloc()/kmem_free() instead of alloca()/memset().

Use %zu and %zx for printf'ing bus_size_t.

Delete the declaration of an unused local variable.
 1.37  04-Mar-2010  dyoung Delete unfinished and unreachable code: ppb_cardbus_setup(),
ppb_cardbus_enable(), ppb_cardbus_disable().
 1.36  03-Mar-2010  dyoung Simplify interrupt (dis)establishment by two source transformations:

- cardbus_intr_disestablish(cc, cf, ih);
+ Cardbus_intr_disestablish(ct, ih);

- ih = cardbus_intr_establish(cc, cf, ...);
+ ih = Cardbus_intr_establish(ct, ...);

Compiles. Untested. Let me know if you use this hardware with NetBSD
any longer.
 1.35  26-Feb-2010  dyoung Use PCI_ constants and macros instead of CARDBUS_. Use
Cardbus_conf_{read,write}() instead of cardbus_conf_{read,write}().
Delete all of the CARDBUS_ constants and macros that replicate PCI_.

Compile-tested, only.
 1.34  25-Feb-2010  dyoung Make fxp at cardbus detach during shutdown.

Stop calling (*cardbus_ctrl) to enable bus mastering, I/O and memory
spaces on the CardBus bridge. cbb(4) always enables that stuff,
anyway. In the process, avoid remembering what BAR we mapped by
writing CARDBUS_{IO,MEM}_ENABLE to sc_cben or sc_cbenable, and
record the BAR in use sc_bar, instead.

Replace more CARDBUS_ constants with PCI_ constants.

Compile-tested, only.
 1.33  25-Feb-2010  dyoung Don't create the device's PCI tag with Cardbus_make_tag(9), but save and
use the tag found in the cardbus_attach_args. Compile-tested, only.
 1.32  24-Feb-2010  dyoung Start to tuck Cardbus under the PCI abstraction. Step #1, textual
substitution: for all practical purposes, pcitag_t and cardbustag_t
are interchangeable, so just use pcitag_t. Ditto pcireg_t and
cardbusreg_t.

While I'm here, don't make a copy (sc_intrline) of
cardbus_attach_args.ca_intrline unless we use it, later.
 1.31  12-May-2009  cegger branches: 1.31.2;
struct device * -> device_t, no functional changes intended.
 1.30  12-May-2009  cegger struct cfdata * -> cfdata_t, no functional changes intended.
 1.29  18-Mar-2009  cegger bzero -> memset
 1.28  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.
 1.27  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.)

merge ktrace-lwp.
 1.16  09-Sep-2005  drochner make this compile again (shadow and const warnings)
I doubt this serves any useful purpose.
 1.15  27-Feb-2005  perry branches: 1.15.4;
nuke trailing whitespace
 1.14  04-Feb-2005  perry de-__P
 1.13  30-Aug-2004  drochner branches: 1.13.4; 1.13.6;
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.
 1.12  02-Aug-2004  mycroft cardbusdevs -> pcidevs
 1.11  23-Apr-2004  itojun pass string length (= boundary info) to pci_devinfo so that we do not run over
the end of memory region
 1.10  24-Nov-2003  lukem fix uninitialised variable warning. XXX: not sure if this is correct
 1.9  01-Jan-2003  thorpej branches: 1.9.2;
Use aprint_normal() in cfprint routines.
 1.8  02-Oct-2002  thorpej Add trailing ; to CFATTACH_DECL.
 1.7  30-Sep-2002  thorpej Use CFATTACH_DECL().
 1.6  27-Sep-2002  thorpej Declare all cfattach structures const.
 1.5  27-Sep-2002  provos remove trailing \n in panic(). approved perry.
 1.4  02-Jun-2002  lukem make this compile again
 1.3  16-May-2002  thorpej branches: 1.3.2; 1.3.4;
* Add "pcitag_t *pba_bridgetag" to pci_attach_args. This is set to
NULL for root PCI busses. For busses behind a bridge, it points to
a persistent copy of the bridge's pcitag_t. This can be very useful
for machine-dependent PCI bus enumeration code.
* Implement a machine-dependent pci_enumerate_bus() for sparc64 which
uses OFW device nodes to enumerate the bus. When a PCI bus that is
behind a bridge is attached, pci_attach_hook() allocates a new PCI
chipset tag for the new bus and sets it's "curnode" to the OFW node
of the bridge. This is used as a starting point when enumerating
that bus. Root busses get the OFW node of the host bridge (psycho).
* Garbage-collect "ofpci" and "ofppb" from the sparc64 port.
