== 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.
== DETAILS
Turns out the cause of the crash was a bad cast, resulting in a
function call to nowhere.
Also, I think the DSI exception handler only works on the primary core;
when this was happening in the background thread, I got a black
screen error instead.
Next up: finishing up the GCA driver.
== DETAILS
I've created the concept of a hid_driver_instance_t which is basically
a central place to store the hid pad driver, hid subsystem driver,
the pad list, and the instance data for the above in a central location.
The HID pad device drivers can use it to perform HID operations in a
generic manner.
This is more-or-less a pause point so I can catch up with upstream.
== TESTING
Haven't tested this yet. Compiles without warnings though!
== DETAILS
- detect() methods in device_* files now check for VID/PID
instead of just returning false
- add "name" field on hid device, mainly for logging purposes
== TESTING
Verified my WiiU GC adapter detected properly
