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?).

some other constants. These are provided by sys/param.h now.
|
|
- use sc->sc_dev to get device_t
- fix inconsistent aprint_error_dev(9) usage
- some KNF and wrap long lines

XXX: still doesn't work (command timeout on data xfer).

all devices on the bus are really reset.
- Block interrupts on Bus Reset, and check it periodically until the
reset is released. On some 32UDE devices (probably the earlier ones)
the RST line looks unstable without the termination power and may
suffer ~continuous Bus Reset interrupts.
- Change number of scatter/gather segments from 16 to 17, to allow
non-page-aligned 64KB transfer on 4KB/page platforms.

It seems I have always tested with targets those ID >= 3,
and that I am the only user of this driver.

- kthread, callout, devsw API changes
- select()/poll() improvements
- miscellaneous MT safety improvements

future commit will replace use of TRUE and FALSE with true and false.
|
|
|
|
- fix a couple of unused bugs
- no more -Wno-unused for i386
|
|
In this case, the transfer count becomes larger than the reality,
and this fix works around it.
- Add missing bus_dmamap_unload() in attach failure path.

- fix variable shadowing
- remove unneeded casts
