This patch adds a mapping to the game controller database header for the
Sony Dualshock 4 controller in Linux.

Thanks, I added it here: https://github.com/gabomdq/SDL_GameControllerDB

Went a step further and added Windows and Mac OS X support, too.

Tested with USB cable (couldn't coerce Bluetooth to work at all,
unrelated to SDL).

You can send the patch to me (or the mailing list). What did you have to
do to make this work? I literally get an error in the kernel logs on Mac
OS X when I pair the device, and a dictionary that IOKit is supposed to
give me comes in as a string with the same error message as the kernel log.

I discovered that this example application could see all the controller meta-data

https://developer.apple.com/library/mac/samplecode/HID_Dumper/Introduction/Intro.html#//apple_ref/doc/uid/DTS40008869-Intro-DontLinkElementID_2

it uses a different HID api than what SDL uses.
IOHIDManagerCreate etc..

but they're really really similar. So I did something hacky, I match up serial numbers and use
IOHIDManagerCreate to grab the meta-data, turn it into a dictionary and call HIDAddElement(element, pDevice); on it.
Because the API that SDL still works. It just has a problem getting the meta-data of the device. But once you have it, you're good to go.

I changed two files darwin/SDL_sysjoystick.c & darwin/SDL_sysjoystick_c.h

I can just send the files to you?

Really the best long term solution is to re-write the wrapper code to use IOHIDManager API. It seems like that is the newer one of the two?

--david

P.S. I am excited to help! developing with the PS4 controller on mac is so so much fun

dropbox link with the two files

-- david

Ah, yes, this API was introduced in Mac OS X 10.5. Updating SDL to use
it is on the TODO list. I'm just surprised the controller works through
that API and not the older one (I always assumed HIDManager was built on
top of the old HID Utilities API, to offer a nicer API to
programmers...perhaps I was wrong about that).

Bluetooth support requires BlueZ 5.14 or later as there were some issues
preventing the controller from connecting. Unfortunately, Debian based
distros are still on BlueZ version 4.x and won't work unless someone
backports the necessary fixes or they move to version 5.

Currently kernel 3.14 will have full support (rumble, LEDs and
accelerometers) for the DS4 on USB. Full featured support on Bluetooth
required some architectural changes in the Linux HID driver and full
support won't be in until 3.15.
