== DETAILS
Hooray for conditional compile directives.
Moving things around broke things in unexpected ways on non-WiiU builds.
Well, not *completely* unexpected. But still.
Changes:
- Move some typedefs around to avoid circular include dependencies
- Include the file where the HID driver definition got moved to
== TESTING
- verified build for Wii U still runs successfully
- did a local build without any errors (some weird warnings, but since they
happen in code I didn't change, I'm assuming they're pre-existing?)
== DETAILS
I think this will fix the problem with duplicate pads--pads weren't properly
de-initializing and registering as disconnected. When a pad is disconnected,
the slot should properly release now.
retro_bits_t turned into input_bits_t and there were parts of my
code that needed to update.
== TESTING
No idea if upstream changes broke anything, but it compiles cleanly
now.
== DETAILS
TIL that it's bad to call synchronization code from callbacks.
To avoid that, I made the following changes:
- Implemented an atomic swap (see previous commit) to avoid explicit
locking when working with the event list
- ensure locks are only acquired in either the main thread or the
I/O polling thread
- use an explicit polling loop; we still use async reads, but the
read doesn't immediately re-invoke itself.
- remove the sleep in the polling thread.
- remove unnecessary locking in the thread cleanup call--verified that
the list can't be modified while it is being executed.
== TESTING
I tested locally, and was able to disconnect/reconnect USB devices several times without the worker thread getting deadlocked.
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.
