Resources on the GPU can be fairly convoluted and involve overlaps which can lead to the same GPU resources being utilized with different views, we previously utilized fences to lock resources to prevent concurrent access but this was overly harsh as it would block usage of resources till GPU completion of the commands associated with a resource. Fences have now been replaced with locks but locks run into the issue of being per-view and therefore to add a common object for tracking usage the concept of "tags" was introduced to track a single context so locks can be skipped if they're from the same context. This is important to prevent a deadlock when locking a resource which has been already locked from the current context with a different view. |

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 accuracy of their HLE implementations of Switch subsystems make it an amazing reference. The team behind the project has been extremely helpful with any queries we've had and have constantly helped us with any issues we've come across. It should be noted that Skyline is not based on Ryujinx.
-
yuzu: Skyline's shader compiler is a fork of yuzu's shader compiler with Skyline-specific changes, using it allowed us to focus on the parts of GPU emulation that we could specifically optimize for mobile while having a high-quality shader compiler implementation as a base. The team behind yuzu has also often helped us and have graciously provided us with a license exemption.
-
Switchbrew: We've extensively used Switchbrew whether that be their wiki with its 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.
