== DETAILS
- DS3 analog wasn't working mainly because I forgot to actually declare the
axes in input/input_autoconfig.c when declaring the pad. Whoops.
- I also moved the axis decoding logic to a more central place, because it
clearly is not Wii U specific.
- Removed some dead commented-out code
== TESTING
Can use analog inputs on both GCA and DS3. Tested in Mario 3 on Nestopia core.
Haven't tested with any actual analog games, but I did confirm via logging
that the correct ranges are produced.
Fortunately, the gcc port implements the builtins and, from basic
testing, they seem to work.
This is only really useful on Wii U--other platforms have more
robust atomic operations, or aren't using gcc to build.
== DETAILS
1. Noticed that the HID driver wasn't loading after setting WIIU_HID=1. Found
that the HID driver init was ifdef'd out. Removed that.
2. Current theory around "System Memory Error 160-2203" is in-memory
corruption. So, to try to identify it:
- Created a routine that does a hex dump of the RPX over the logger. (I
have a python3 script that can extract the hex dump back into a binary
file). If a SME occurs with this routine enabled, we can see if the
corruption is happening at read-time, or somewhere between when we send
the RPX to the loader and try to execute it.
- I noticed that we allocate slightly more memory than the RPX actually
needs, and we don't zero the memory, which means there's a handful of
bytes at the end that could be anything. I added a call to memset() to
zero out the memory prior to loading the RPX off the SD card.
And, of course, after adding those, I haven't been able to reproduce the
System Memory Error, so maybe the uninitialized memory was the problem?
Here's hoping.
== DETAILS
- Add *.swp to gitignore so editor swap files don't get committed
- Remove unneeded commented-out defines from WiiU build
- Start on fix for DSI when switching cores on WiiU
== TESTING
Sigh. I'm back at "System Memory error", which makes me think the problem
might be the SD card. (On the plus side, I manually verified the hash so
at least the copy process is working).
So, that's to say that I can't actually test to see if the DSI error is
fixed.
== 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.
can load *.slangp and *.slang files. since there is no runtime compiler,
precompiled shaders (*.gsh) need to be present next to each *.slang
source file.
== DETAILS
RetroArch's general HID drivers are intended as a full-on substitute for
other input drivers such as XInput, DInput, SDL, etc. The Wii U port is,
to my knowledge, the first case of heterogenous input drivers working
concurrently.
As such, I've moved things around:
- The HID driver source is moved into the wiiu/input/ directory alongside
the joypad subdrivers.
- We no longer use the input_hid_init_first() method to instantiate; instead
we just init the wiiu HID driver directly.
- The HID pad driver and HID subsystem driver enjoy a tighter coupling,
mainly having to do with the initialization of the joypad connections
list, because there's no way to inform the HID driver's init() method
how many slots to allocate.
== TESTING
Will test in a moment, but at least it compiles cleanly. ;)
== 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
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.
There was some type confusion around IOS_Open with libiosuhax, leading
to it treating the first instruction of that function as an address to
point to. Adding -D__WUT__ lets it know that we are using proper symbols
and not function pointers.
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.
Inspired by Makefile.win; this commit will hide compiler commands from
being printed to the shell. Old behaviour can be restored by running
"make -f Makefile.wiiu V=1". Should make it harder to miss warnings now.
