* Added usb hid controllers for the famous ZeroDelay encoder and also for "Kade: Kick Ass Dynamic Encoder" to be able to use some custom arcade sticks.
* Add accidentally missing change to Makefile

* Fix Sixaxis gamepad operation
== DETAILS
It looks like commit 78e7d23c144c862d65ae1bf7ee41a1228bdfa380 broke
the DualShock. Sorry, @revvv, but this is probably going to break the
Retrode driver. We'll need to figure out a different solution.
* Fix a bunch of HID implementations
== DETAILS
As mentioned in the previous commit, the thing that broke the DS3
driver was a change to the wiiu HID handler, which did some pointer
math on the data buffer.
The thing is.. there's no reason to do that pointer math. Yet, I found
the same thing on almost every other HID driver: OSX, libusb, wiiusb.
The only other HID driver that did not do this was the Bluetooth
HID driver.
It doesn't make any sense. The only reason it doesn't crash is because
the memory right before the buffer is valid memory.
Change summary:
- remove the weird pointer math from all HID controllers
- remove the `#ifdef apple ...` in the ds3 and gamecube adapter
drivers, because it's no longer needed.
- in the pad packet handlers, decrement data buffer offset references
to account for the removal of the buffer manipulation.
* Fix DualShock 4
== DETAILS
Should've only subtracted 1, not 2; and now the pad works.
Also, added a PID to cover newer model DS4s. I picked "R2" out of the air
for the constant.
Tested on Mac OS
* Really really fix iohidmanager_set_report
A huge apology to @23rd for insulting your fix. I was wrong to call you
wrong.
That left the question: why did that change break the DS3?
Well, it's because `IOHIDDeviceSetReport` expects the report buffer to be
just the report. All of RA's HID SetReport calls include the report number
in the first byte, so we have to trim that off.
We actually do this in a different invocation of `IOHIDDeviceSetReport`
elsewhere in the file! This commit applies that same logic to
`iohidmanager_set_report`
This has two benefits:
1. The DS3 works
2. The DS3 no longer requres the user to press the PS button to activate
it the first time. You plug it in and it Just Works, just like on Wii U.
* MacOS: Fix sixaxis on MacOS 12.x
== DETAILS
Mac OS 12.x "Monterey" dropped some built-in support for the
Sixaxis controller--exactly what changed is unclear, but other
projects reported similar issues with the OS.
This commit ports the work done on SDL, which is basically to
read two feature reports after writing out the activation report.
I think we did this at one point in the past, but it got lost
among HID driver rewrites.
I've tested this locally and it resolves the issue; after connecting
the sixaxis and pressing the Playstation button, the pad is registered
and works successfully.
I have not tested this on other platforms.
* Gracefully handle incomplete HID implementations
== DETAILS
Not all HID drivers implement all HID methods; since this controller
has a magic sequence that requires the ability to set and get HID
reports, we need to make sure we don't crash if we're running on
an incomplete implementation.
- Add a null check for the driver methods and log useful info if checks
fail
- Fix minor formatting
* (joypad_connection) Small optimizations -
* Turn functions static where possible
* Hose strlen call out of loop
* (input_driver.c) General cleanups:
* Some small code/style nits
task_screenshot.c:
* Move widget callback function for screenshots to task_screenshot.c
(file_path.c):
* Turn get_pathname_num_slashes into static function
* path_linked_list_free - always returns true, so get rid of return value
* path_linked_list_new - fix function signature
* path_get_archive_delim - do not NULL-terminate string, already done by strlcpy later on
General:
* Slight optimizations - use int/size_t for loop counter variable instead of unsigned
* Take advantage of fact that strlcpy already NULL-terminates, so don't do this explicitly
outside if we're just going to end up calling strlcpy/fill_pathname_join on it anyway
Controllers with same VID/PID are distinguished by the device name.
1. The Wii U only sends a prefix of the device name.
2. The check preferred the device name over VID/PID which was not
intended.
Example: The device name "USB Gamepad" is truncated to "USB" which
was mapped to "Generic SNES USB Controller", although VID/PID did not
match.
Otherwise autoconfig file can't be found on the Wii U:
VID/PID are not available, so it has to match with 'input_device' and I
don't want to add additional autoconfig files with different
'input_device' strings.
Otherwise the USB gamepad cannot be found, if VID/PID has leading zero.
For example: Retrode gamepad adapter:
vid=1027 (0x403) pid=38849 (0x97c1) becomes
vid=1027 (0x403) pid=-26687 (0xffff97c1)
== DETAILS
The crashes he reported in the gbatemp thread are due to iface
being null (since it's an unsupported device) and unchecked
iface dereferences.
== DETAILS
Put the finishing touches on getting the DS3 to work on Mac OSX.
Basically, there's some differences in the HID interface bewtween
wiiu and osx where OSX expects the first byte of the report to be
the report ID, while wiiu expects that byte to be trimmed off.
I was able to put this behavior in the respective HID
implementations, which eliminated the confusing packet offset
ifdefs.
And, I was able to get the LEDs working again.
== DETAILS
The DS3 driver previously only worked with the Wii U HID implementation.
I adapted this driver from the Linux driver for the DS3. It's not quite
100%--I haven't got the LEDs to work properly--but it's functional.
Going to continue tweaking it to see if I can get the LEDs to work.
== DETAILS
- rewrote the HID deregistration algorithm; it should no longer
cause issues when dealing with multiple pads of the same HID/VID
combo
- fix initialization bug that caused wiimotes to fail to register
without an accessory attached
== DETAILS
The GCA uses a weird HID class that our current filters don't
catch, so we add it.
Needed to do a small amount of tweaking on the GCA driver to
account for iohidmanager weirdness.
== DETAILS
The HID drivers in `input/connect/` were missing an implementation
for button(), so I added it. The only exception is the wii driver,
which is really complicated and more than I wanted to try to tackle--
especially since WIIU has its own wiimote drivers.
== DETAILS
Use a little trickery to ensure the GCA driver continues working
with other HID implementation.
I've expanded the joypad implementation to support multi-pad devices.
However, this requires changes to each HID implementation to actually
function.
I've made the necessary changes for WIIU, but I don't have the means
of making the change in the other HID implementations.
So, I've built in a backwards-compatibilty mode for the driver.
The trick is to have an identifier byte at the top of both data structs
that the driver returns. We can then use that byte to determine which
of the structs has been passed to the pad functions and act accordingly.
In the GCA case, for non-wiiu platforms, it will simply expose port 1
of the GCA and the other 3 ports do nothing.
== DETAILS
cause of crash: trying to deference init when it's null
the reason it was going into deregister: the HID/VID lookup was
failing because it wasn't getting initialized first
cause of 2nd crash: the "end of pad list" method looked for an entry
with a magic value, so we add an end marker
== DETAILS
I'm going to need to re-implement the abstraction between HID device
and gamepad; the changes here lay down some foundation for that work.
- reduce logging priority of some statements I modified while debugging
- factor out the pad driver lookup into its own method
- fix so the pad driver list isn't re-initialized every invocation
- add the button() method for the GCA driver
== DETAILS
When I first implemented the Wii U HID architecture, I ended up
having to design my own implementation because, at the time, I did
not have a way to read the HID device string to allow the existing
code to successfully detect the gamepad.
After spending some time experimenting, I've figured out how to
do this. And that means I can better align the HID driver with other
platforms.
change summary:
- create a single state structure for all three sub-types of wiiu pads
(kpad, wpad, and hid)
- eliminate confusing duplicate pad lists
- eliminate confusing duplicate HID pad drivers (ds3, gamecube
adapter, etc)
- ensure the ds3 driver still works
== DETAILS
After a bisect, the culprit was changing the gamepad interface from
returing a single button (bool) to multiple (int16).
The issue is that the Wii U gamepad (and presumably the Pro controller too)
have more than 16 buttons, which means some buttons get lost. Notably, L3 (18)
and R3 (17).
The solution: use int32 instead of int16.
I did a test build and confirmed that this change restores L3/R3 functionality
with the gamepad. Don't have a pro controller to test, but it should work too.
