EmuWindow::PollEvents was called from the GPU thread (or the CPU thread
in sync-GPU mode) when swapping buffers. It had three implementations:
- In GRenderWindow, it didn't actually poll events, just set a flag and
emit a signal to indicate that a frame was displayed.
- In EmuWindow_SDL2_Hide, it did nothing.
- In EmuWindow_SDL2, it did call SDL_PollEvents, but this is wrong
because SDL_PollEvents is supposed to be called on the thread that set
up video - in this case, the main thread, which was sleeping in a
busyloop (regardless of whether sync-GPU was enabled). On macOS this
causes a crash.
To fix this:
- Rename EmuWindow::PollEvents to OnFrameDisplayed, and give it a
default implementation that does nothing.
- In EmuWindow_SDL2, do not override OnFrameDisplayed, but instead have
the main thread call SDL_WaitEvent in a loop.
Upon further investigation, these commands allow temporary vibrations even when the "Controller Vibration" system setting is disabled. As a result, vibrations are allowed when either the system setting or this flag is set to true. Therefore, we can only block vibrations when both flags are set to false.
Previously we used a vibration filter that filters out amplitudes close to each other. It turns out there are cases where this results into vibrations that are too inaccurate. Remove this and move the 100Hz vibration filter (Only allowing a maximum of 100 vibrations per second) from sdl_impl to npad when enable_accurate_vibrations is set to false.
A vibration device is an input device that returns an unsigned byte as status.
It represents whether the vibration device supports vibration or not.
If the status returns 1, it supports vibration. Otherwise, it does not support vibration.
Allows for enabling and modifying vibration and vibration strength per player.
Also adds a toggle for enabling/disabling accurate vibrations.

The implementation of these commands seem incomplete and causes rumble in Super Mario Party to stop working since only EndPermitVibrationSession is called. Thus, these are better off being marked as a stub until this can be investigated more thoroughly.
Sending too many state changes in a short period of time can cause massive performance issues.
As a result, we have to use several heuristics to reduce the number of state changes to minimize/eliminate this performance impact while maintaining the quality of these vibrations as much as possible.
This allows setting the vibration strength percentage anywhere from 1% to 100%.
Also hooks up the remaining motion button and checkbox in the Controller Applet.
Some parameters need to be doubleword aligned due to the presence of the applet_resource_user_id.
Previously, this value was invalid in many commands where it was not doubleword aligned when popped.
The first u32 describes the vibration device type which is a Linear Resonant Actuator used in Nintendo Switch controller hardware.
The second u32 describes the vibration device position, in this case distinguishing between left and right vibration actuators.
Pro Controllers have 2 LRAs each that can vibrate independently of each other, which means they have 2 distinct vibration device handles to distinguish between the two actuators.
Similarly for joycons, the left joycon can be distinguished from the right joycon through the vibration device handle since each joycon has 1 LRA.
Resolves numerous deprecation warnings throughout the codebase due to
inclusion of this header. Now building core should be significantly less
noisy (and also relying on less global state).
This also uncovered quite a few modules that were relying on indirect
includes, which have also been fixed.
The interrupt handler contains a std::atomic_bool, which isn't copyable
or movable, so the special move member functions will always be deleted,
despite being defaulted.
This can resolve warnings on clang and GCC.
Some games like Cave Story+ set invalid values in the ControllerPrivateArg's mode and caller fields.
Use other fields to determine the appropriate mode and caller should either or both fields be invalid.
- This works similiar to GetAlbumContentsFileListForApplication.
- Since we do not implement the album, this should be safe to stub for now.
- Used by Super Smash Bros. Ultimate (newer updates) in World of Light.
Unicorn long-since lost most of its use, due to dynarmic gaining support
for handling most instructions. At this point any further issues
encountered should be used to make dynarmic better.
This also allows us to remove our dependency on Python.
This commit aims to implement the NVDEC (Nvidia Decoder) functionality, with video frame decoding being handled by the FFmpeg library.
The process begins with Ioctl commands being sent to the NVDEC and VIC (Video Image Composer) emulated devices. These allocate the necessary GPU buffers for the frame data, along with providing information on the incoming video data. A Submit command then signals the GPU to process and decode the frame data.
To decode the frame, the respective codec's header must be manually composed from the information provided by NVDEC, then sent with the raw frame data to the ffmpeg library.
Currently, H264 and VP9 are supported, with VP9 having some minor artifacting issues related mainly to the reference frame composition in its uncompressed header.
Async GPU is not properly implemented at the moment.
