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?).

Kill some more extern struct cfdriver declarations.

- Use aprint*() instead of printf() in xxx_attach().
- Add missing aprint_naive("\n");
- KNF

| 1.18 |
| 20-Aug-2015 |
christos | include "ioconf.h" to get the 'void <driver>attach(int count);' prototype.
|
| 1.17 |

uebayasi | Use needs-count for # of pseudo instances; suggested by cube@.
|
| 1.16 |
| 25-Feb-2014 |
pooka | branches: 1.16.6;
Ensure that the top level sysctl nodes (kern, vfs, net, ...) exist before
the sysctl link sets are processed, and remove redundancy.
Shaves >13kB off of an amd64 GENERIC, not to mention >1k duplicate
lines of code.

| 1.15 |
| 20-May-2013 |
mbalmer | branches: 1.15.2;
Make the gpiosim(4) device a 64 bit wide GPIO.
|
| 1.14 |
| 02-Jun-2012 |
dsl | branches: 1.14.2;
Add some pre-processor magic to verify that the type of the data item
passed to sysctl_createv() actually matches the declared type for
the item itself.
In the places where the caller specifies a function and a structure
address (typically the 'softc') an explicit (void *) cast is now needed.
Fixes bugs in sys/dev/acpi/asus_acpi.c sys/dev/bluetooth/bcsp.c
sys/kern/vfs_bio.c sys/miscfs/syncfs/sync_subr.c and setting
AcpiGbl_EnableAmlDebugObject.
(mostly passing the address of a uint64_t when typed as CTLTYPE_INT).
I've test built quite a few kernels, but there may be some unfixed MD
fallout. Most likely passing &char[] to char *.
Also add CTLFLAG_UNSIGNED for unsiged decimals - not set yet.

mbalmer | branches: 1.13.2;
Unconditionally include <sys/modules.h>.

mbalmer | u_int32_t -> uin32_t.
|

| 14-Aug-2011 |
mbalmer | fix indents
|
| 1.8 |
| 12-Aug-2011 |
mbalmer | gpio(4) and gpiosim(4) can now be built and used as modules. While here,
make some functions static.
|
| 1.7 |
| 06-Dec-2009 |
dyoung | Delete unnecessary device-activation hooks. Simplify the rest.
|
| 1.6 |
| 07-Aug-2009 |
mbalmer | branches: 1.6.2;
Properly teardown the sysctl node and detach child driver if gpiosim gets
detached itself (e.g. when the 'drvctl -d gpiosimX' command is entered).
|
| 1.5 |
| 06-Aug-2009 |
mbalmer | For the sake of correctness, call pmf_device_deregister() in the detach
function.
|
| 1.4 |
| 28-Jul-2009 |
drochner | add dummy pmf registration to allow suspend
|
| 1.3 |
| 27-Jul-2009 |
mbalmer | Do not attach gpiosim(4) at root, but make it a pseudo device.
With help from Matthias Drochner, thanks!
|
| 1.2 |
| 26-Jul-2009 |
mbalmer | Simplify the use _a lot_ by hooking this to sysctl instead of bio(4).
When it attaches, it creates a hw.gpiosimN.value sysctl node which can
then be used to manipulate the simulated device state.
|
| 1.1 |
| 25-Jul-2009 |
mbalmer | Rework the GPIO framework. Tie it to the kauth(9) framework to control
access to the GPIO pins. Device drivers using GPIO pins can now be
attached and detached at runtime. GPIO pins can be named for easier
reference from userland programs. Introduce a new gpiosim(4) driver,
which is used for development.
