== DETAILS
The current HID implementation assumes a very low-level USB library
is being used. This causes a problem on Wii U, because the Cafe OS
only exposes a high-level interface.
To get these functions exposed to the HID pad drivers, I had to make
three changes:
1. I added the legacy "send_control" function to the HID driver
interface
2. I modified the signature of pad_connection_pad_init() to send the
driver pointer instead of the function pointer
3. I updated the HID pad drivers to keep the pointer to the driver
instead of the function pointer, and updated the calls into the
send_control function as appropriate
4. I updated the HID drivers to use the new pad init signature
== TESTING
Untested, in theory it should work without a hitch because at this
point all I've done is abstract things a little. I still need to
update the HID pad drivers to use the Wii U-specific calls as
appropriate.
== 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.
