=== DETAILS
Replaced includes for things that aren't standard library headers so
they use quotes instead of brackets.
Also fixed up a couple of headers that had include-order dependencies.
=== DETAILS
Since @aliaspider wants the `wiiu/` to be something of a mini-SDK, I've
reorganized the code I put in there:
- `wiiu/main.c` now only has the ELF/RPX entrypoints, and the code used
by those entrypoints, with RA code removed (e.g. swapped retro_sleep()
for usleep()). These entrypoints then call main() ...
- Moved `main()` and its support functions back into `frontend/drivers/platform_wiiu.c`
I also renamed some of the support functions I wrote, and better
organized them within the code.
- Moved `wiiu/input/` into the `input/` hierarchy:
* The joypad drivers now live in `input/drivers_joypad/wiiu/`
* The HID driver now lives in `input/drivers_hid/`
* The Wii U specific headers now live in `input/include/wiiu`
* I added `input/include` into the include search path to avoid
using really ugly relative includes
== DETAILS
Whereas the last commit had a hack (that disabled the wiimote
driver in the process), this has.. well, a *different* hack that
allows pads to register in any order.
Note that due to the initialization routines, the gamepad will still
likely always get slot 0. Not sure if this can be overridden via config
or not.
== TESTING
Tested locally with GC adapter
== DETAILS
Now that I have a working implementation, it's time to tidy up a bit:
- there was no need for the HID subsystem's object data to have a reference
to the global hid state (since it's global), so removed it.
- refactored the users of that member to use the global state, defining
reusable macros.
- reorganized the information in *.h files
- removing the hid state also made the constructor changes to the hid driver
unneeded, so I reverted those changes.
== TESTING
Confirmed clean build. Haven't tested the build yet to make sure everything
still works, though.
== DETAILS
- Added a new method to the joypad_connection_t interface for
getting a single button
- wired everything into the hidpad driver
- for testing purposes, hacking the top-level joypad driver
so that kpad isn't used
- add a new RARCH_LOG_BUFFER method to verbosity for logging the
contents of a binary buffer (useful for writing/debugging pad drivers)
- fix a few bugs in the wiiu GC pad driver
The button mapping isn't quite right, and I'm not sure what's
going wrong.
== DETAILS
We're trying to track down the source of crashes when switching cores.
To rule out the HID code, this commit does the following:
- Wraps the library imports in an ifdef
- Wraps the object files in conditionals in Makefile.wiiu
- In wiiu_joypad, calls into the hidpad driver are wrapped in ifdef
== TESTING
This didn't solve the "System memory error" crash I've been experiencing.
But, maybe it will impact the other flavors of crashes others are seeing.
== DETAILS
Well, after a lot of code analysis, this seems like the
best way to handle things on the Wii U without also completely
re-architecting the I/O handling in RetroArch.
How it works:
- the top-level wiiu_joypad driver is now nothing more than a
delegator.
- the wiiu-specific drivers live in `wiiu/input/`
- wpad_driver.c handles the WiiU gamepad
- kpad_driver.c handles the wiimotes
- hidpad_driver.c will handle HID devices like the GC adapter, DS3/DS4, etc.
(I say "will" because this isn't implemented yet)
== TESTING
Haven't actually tried the build to see if it works, but it does
compile.
== DETAILS
Looking at the apple input driver gave me an idea--moving the
HID driver into the wiiu_input_t data instead of piggy-backing
it off the wiiu_joypad driver.
- Remove changes to wiiu_joypad
- Add equivalent to wiiu_input
This is probably broke as hell. Haven't tried to compile.
== DETAILS
I did a minimalist edit of the HID thread that stripped out all
HID* syscalls, and this stopped the crashing. I then re-added just
the HIDSetup() and HIDTeardown() calls, and the crash came back.
This smells like an OS bug. To work around it, I've put the
HIDSetup() and HIDTeardown() calls into the app init/shutdown
section, so they only get called once in the application lifetime
and not each time the input driver is initialized.
== DETAILS
We discovered that the controller_patcher code was causing
the WiiU to intermittently crash when switching ROMs.
Changes:
- Completely extricates the controller_patcher code
- Create a skeleton wiiu_hid driver
- Wire up the build system to build/link it successfully
== TESTING
Has not been tested. Probably doesn't crash, since the
skeleton driver is just a copy of the null driver.
As discussed in libretro#5357; controller_patcher is now optional. It's
off by default; though this could be changed with a simple makefile
tweak (ENABLE_CONTROLLER_PATCHER ?= 1, perhaps?)
To re-enable controller_patcher; append ENABLE_CONTROLLER_PATCHER=1 to
your usual make command.
controller_patcher was the only user of c++ constructors in the Wii U
port, so you'll need 26a006c in your tree otherwise you will have a
blackscreen on startup.
Oops! Didn't do this quite right the first time round.
This commit fixes RETRO_DEVICE_ID_POINTER_PRESSED, which would always
return 0 due to to an implicit case to int16_t. Basically, we'd do
(val & 0x00080000) & 0xFFFF; which would return 0 every time. Fixed that
by wrapping it in a ternary. Yes, I know we could use a rotation, but
for a boolean value it really doesn't matter.
I also rewrote scaleTP to deal entirely in integers. While the
floating-point math was theoretically faster on PowerPC; it gets awkward
to cast -0x7FFF to a float.
Speaking of, the driver now actually conforms to the libretro API. Not
sure how I managed to not see the spec; but hey, now its fixed.
RETRO_DEVICE_POINTER_ID_X/Y will now return values between -0x7FFF and
0x7FFF like they're supposed to.
Big thanks to @r-type for hounding me to fix this.
Partially addresses #5294; we still need mouse emulation.
This hopefully fixes the issues when you try to use 2 Controllers with
the same vid/pid at the same time.
Tested with 2 DS4 controller via the Hid to VPAD Network Client.
Adapters with multiple ports (like the official GC-Adapter) are still
working
Allow using the Gamepad's touch screen as a RETRO_DEVICE_POINTER.
Methodology could use some work, had to add an extra axis to
joypad in order to get the data transferred into the input driver.
Feel free to change this.
Needs to emulate RETRO_DEVICE_LIGHTGUN to really be useful.
Potential for Wiimote IR in future.
Partially addresses libretro/RetroArch#5294
