== DETAILS
Starting to implement the I/O handling on the HID driver.
The old implementation basically had a never-ending HIDRead() callback
set up, so that callback N would start the read process for invocation
N+1.
We will take the same approach here; but now that the I/O thread is
happenning on its own core, we should be able to let it run full-
throttle without impacting emulator performance.
Of course, this hinges on the callback actually running on the same
core as the syscall was initiated on.
== TESTING
Can confirm that the read_loop_callback gets invoked on the same core
that the HIDRead() was invoked on.
== DETAILS
This implements the WiiU-specific functions.
Since the wiiu_hid_t data structure contains the handle and interface
index, the method signatures can be simplified quite a bit. And since
(at least for now) we want these to be synchronous, we don't need to
expose the callback parameters.
== DETAILS
The handshake stuff is derived from the old HID2VPAD, just in knowing
what data goes in what report.
- Added the HID_REPORT_ flags to syshid.h
- Renamed the generic "REPORT_TYPE" flags to be meaningful
- also fixed incorrect parameter list for set_protocol
== TESTING
The functions aren't implemented in wiiu_hid.c just yet,
so this is gonna crash if you try to run it.
== DETAILS
The old code was crashing; I did a minimalized branch and the crash
went away, so I'm bringing that over here. Meaning I'll have to
redo some of the other work I'd put in, but oh well.
(now watch it start crashing again)
== TESTING
Can confirm it builds. Wii U is busy ATM so I can't test.
== 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.
Thanks for @gblues for finding the strcmp bug.
I've removed the opcode display since it's a bit unsafe - if the
exception handler causes a DSI; Cafe OS will take over and freeze up the
console. This is obviously not a good thing. There are possible
situations where memory is executable and not readable; so this is just
about covering all bases until a better solution can be implemented.
Maybe we can experiment a bit more once this handler isn't being used so
often ;)
Coreinit seems to get special handles, so adding a special case should
make its relative addresses actually become helpful again. Let's just
hope __PPCExit stays at 0x180!
Also added the violating opcode to the DSI message; may have to move it
in case it pushes stuff off the end of the screen.
Untested at time of commit. Hopefully this should make debugging #5357 a
bit easier...
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
- c++ static constructors/destructors fix for rpx builds.
- building both rpx and hbl elf formats doesn't require a clean step
inbetween anymore, both can be now built in a single make call.
