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?).

This change modifies the mainbus(4) entry point for all x86 sub-archs
in the following way:

i) It provides a unified entry point in
   x86/x86/mainbus.c:mainbus_attach()
ii) It carves out the preliminary bus attachment sequence that is
   common to all sub-archs into
   x86/x86/mainbus.c: x86_cpubus_attach()
iii) It consolidates the remaining pathways as internal callee
   functions so that these may be called piecemeal if required. A
   special usecase of this is XEN PVHVM which may need to call the
   native configure path, the xen configure path, or both.
iv) It moves the driver private data structures from
   i386/i386_mainbus.c to an x86/ level one. This allows for other
   sub-arch's to do similar, if needed. (They do not at the moment).
v) For dom0 kernels, it enables 'acpi0 at mainbus?' and
   'acpi0 at hypervisorbus'. This serves two purposes:
   a) To demonstrate the possibility of dynamic configuration tree
      traversal ordering changes.
   b) To allow for the common acpi_check(self, "acpibus") call in
   x86/mainbus.c to not barf when it is called from the dom0 attach
   path. We allow for the acpi0 device to be a child of mainbus with
   the changes to amd64/conf/XEN3_DOM0 and i386/conf/XEN3PAE_DOM0
   without actually probing further in the code. This path will later
   be pursued in a PVHVM boot codepath.

There should be no operative changes with this change. If there are,
please complain loudly.

Revision 1.1 / (download) - annotate - [select for diffs], Sat Dec 22 06:33:36 2018 UTC (5 years, 3 months ago) by cherry
Branch: MAIN

Move mainbus(4) driver files in various x86 sub-archs to name prefixed
versions. This allows us to further modularise them by unifying common
bus probe code in x86/x86/mainbus.c to  be introduced next.

This commit has no functional changes. It is done for ease of
visibility of newer diffs in the queue.
