 1.38  25-Sep-2022  thorpej Remove unnecessary include of <sys/malloc.h>.
 1.37  21-Jul-2022  andvar fix typos in comments and log messages, mainly s/intrrupt/interrupt/.
 1.36  07-Aug-2021  thorpej Merge thorpej-cfargs2.
 1.35  24-Apr-2021  thorpej branches: 1.35.8;
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?).
 1.34  07-Jul-2020  thorpej branches: 1.34.4;
Overhaul the interface to pci_configure_bus():
- Don't expose how PCI bus configuration resource management is implemented.
Provide a new resource provider API:

==> pciconf_resource_init() -- Initialize a PCI configuration resources
container.
==> pciconf_resource_add() -- Add a PCI configuration resource to the
container (I/O, MEM, or prefetchable MEM). Multiple resources of
each type may be added.
==> pciconf_resource_fini() -- Tear down the PCI configurtation resources
container once the bus has been configured.

This is much easier to use than the previous method of providing an
extent map for each kind of resource, and works better for e.g. ACPI
platforms that provide potentially multiple PCI resources in tables
provided by firmware.

- Re-implement PCI configuration resource management using vmem arenas,
rather than extent maps.
 1.33  14-Jun-2020  chs replace EX_NOWAIT with EX_WAITOK in device attach methods.
remove checks for failures that can no longer occur.
 1.32  02-Oct-2015  msaitoh PCI Extended Configuration stuff written by nonaka@:
- Add PCI Extended Configuration Space support into x86.
- Check register offset of pci_conf_read() in MD part. It returns (pcireg_t)-1
if it isn't accessible.
- Decode Extended Capability in PCI Extended Configuration Space.
Currently the following extended capabilities are decoded:
- Advanced Error Reporting
- Virtual Channel
- Device Serial Number
- Power Budgeting
- Root Complex Link Declaration
- Root Complex Event Collector Association
- Access Control Services
- Alternative Routing-ID Interpretation
- Address Translation Services
- Single Root IO Virtualization
- Page Request
- TPH Requester
- Latency Tolerance Reporting
- Secondary PCI Express
- Process Address Space ID
- LN Requester
- L1 PM Substates
The following extended capabilities are not decoded yet:
- Root Complex Internal Link Control
- Multi-Function Virtual Channel
- RCRB Header
- Vendor Unique
- Configuration Access Correction
- Multiple Root IO Virtualization
- Multicast
- Resizable BAR
- Dynamic Power Allocation
- Protocol Multiplexing
- Downstream Port Containment
- Precision Time Management
- M-PCIe
- Function Reading Status Queueing
- Readiness Time Reporting
- Designated Vendor-Specific

 1.29  27-Jan-2012  para converting extent(9) from malloc(9) to kmem(9)
preceding kmem-vmem-pool-uvm patch

releng@ acknowledged
 1.28  17-May-2011  dyoung branches: 1.28.4; 1.28.8;
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:

Patch by Slava Semushin <slava.semushin@gmail.com>

Again, this was tested by comparing obj files from a pristine and a patched
source tree against an i386/ALL kernel, and also for src/sbin/fsck_ffs,
src/sbin/fsdb and src/usr.sbin/makefs. Only changes in assert() line numbers
were detected in 'objdump -d' output.
 1.14  29-Mar-2006  thorpej branches: 1.14.8;
Use device_private().
 1.13  11-Dec-2005  christos branches: 1.13.4; 1.13.6; 1.13.8; 1.13.10; 1.13.12;

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.
 1.10  14-Jul-2003  lukem add missing __KERNEL_RCSID()
 1.9  12-Jun-2003  scw branches: 1.9.2;
Add basic support for non-PCI host mode.
 1.8  27-May-2003  scw Add an option to control whether the GT's internal PCI Arbiter should
be enabled or not.
 1.7  04-Apr-2003  matt Remove #define DEBUG. (this was working right. The problem I encountered
was due to a bug in PPCBOOT. It was not ordering DIMM space largest to
smallest so that you could badly alignment memory).
 1.6  01-Apr-2003  matt Cleanup PCI support.
 1.5  18-Mar-2003  matt Split PCI initialization out of attach hook.
 1.4  18-Mar-2003  matt Enable I/O & memory access too.
 1.3  18-Mar-2003  matt Do minimal initialization of PCI.
 1.2  16-Mar-2003  matt Cleanup. Move much of the code to bus_space instead of using
private mechanisms.
 1.1  05-Mar-2003  matt Add preliminary support Marvell (Galileo) Discovery System Controllers.
This code was contributed by Allegro Networks.

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.
