PixelyIon 216e5cee81 Separate Guest and Host Presentation + AChoreographer V-Sync Event 
We had issues when combining host and guest presentation since certain configurations in guest presentation such as double buffering were very unoptimal for the host and would significantly affect the FPS. As a result of this, we've now made host presentation have its own presentation textures which are copied into from the guest at presentation time, allowing us to change parameters of the host presentation independently of the guest.

We've implemented the infrastructure for this which includes being able to create images from host GPU memory using VMA, an optimized linear texture sync and a method to do on-GPU texture-to-texture copies.

We've also moved to driving the V-Sync event using AChoreographer on its on thread in this PR, which more accurately encapsulates HOS behavior and allows games such as ARMS to boot as they depend on the V-Sync event being signalled even when the game isn't presenting.

Skyline is an experimental emulator that runs on ARMv8 Android™ devices and emulates the functionality of a Nintendo Switch™ system, licensed under Mozilla Public License 2.0

Contact

You can contact the core developers of Skyline at our Discord. If you have any questions, feel free to ask. It's also a good place to just keep up with the emulator, as most talk regarding development goes on over there.

Special Thanks

A few noteworthy teams/projects who've helped us along the way are:

  • Ryujinx: We've used Ryujinx for reference throughout the project, the amount of accuracy of their HLE kernel implementation is what makes them such an amazing reference. The team behind the project has been really helpful with any queries we've had. It should be noted that Skyline is not based on Ryujinx.

  • Switchbrew: We've extensively used Switchbrew whether that be their wiki with it's colossal amount of information on the Switch that has saved us countless hours of time or libnx which was crucial to initial development of the emulator to ensure that our HLE kernel and sysmodule implementations were accurate.

  • Atmosphère: We've used libmesosphere as another reference for our HLE kernel, it's faithfulness to the HOS kernel helps us a lot. This makes it invaluably important for us as a tool for writing code that can accurately emulate HOS behavior without missing any crucial parts.
