Add multi-level function table (#2228)
* Add AddressTable<T>

* Use AddressTable<T> for dispatch

* Remove JumpTable & co.

* Add fallback for out of range addresses

* Add PPTC support

* Add documentation to `AddressTable<T>`

* Make AddressTable<T> configurable

* Fix table walk

* Fix IsMapped check

* Remove CountTableCapacity

* Add PPTC support for fast path

* Rename IsMapped to IsValid

* Remove stale comment

* Change format of address in exception message

* Add TranslatorStubs

* Split DispatchStub

Avoids recompilation of stubs during tests.

* Add hint for 64bit or 32bit

* Add documentation to `Symbol`

* Add documentation to `TranslatorStubs`

Make `TranslatorStubs` disposable as well.

* Add documentation to `SymbolType`

* Add `AddressTableEventSource` to monitor function table size

Add an EventSource which measures the amount of unmanaged bytes
allocated by AddressTable<T> instances.

 dotnet-counters monitor -n Ryujinx --counters ARMeilleure

* Add `AllowLcqInFunctionTable` optimization toggle

This is to reduce the impact this change has on the test duration.
Before everytime a test was ran, the FunctionTable would be initialized
and populated so that the newly compiled test would get registered to
it.

* Implement unmanaged dispatcher

Uses the DispatchStub to dispatch into the next translation, which
allows execution to stay in unmanaged for longer and skips a
ConcurrentDictionary look up when the target translation has been
registered to the FunctionTable.

* Remove redundant null check

* Tune levels of FunctionTable

Uses 5 levels instead of 4 and change unit of AddressTableEventSource
from KB to MB.

* Use 64-bit function table

Improves codegen for direct branches:

    mov qword [rax+0x408],0x10603560
 -  mov rcx,sub_10603560_OFFSET
 -  mov ecx,[rcx]
 -  mov ecx,ecx
 -  mov rdx,JIT_CACHE_BASE
 -  add rdx,rcx
 +  mov rcx,sub_10603560
 +  mov rdx,[rcx]
    mov rcx,rax

Improves codegen for dispatch stub:

    and rax,byte +0x1f
 -  mov eax,[rcx+rax*4]
 -  mov eax,eax
 -  mov rcx,JIT_CACHE_BASE
 -  lea rax,[rcx+rax]
 +  mov rax,[rcx+rax*8]
    mov rcx,rbx

* Remove `JitCacheSymbol` & `JitCache.Offset`

* Turn `Translator.Translate` into an instance method

We do not have to add more parameter to this method and related ones as
new structures are added & needed for translation.

* Add symbol only when PTC is enabled

Address LDj3SNuD's feedback

* Change `NativeContext.Running` to a 32-bit integer

* Fix PageTable symbol for host mapped

Ryujinx

An experimental Switch emulator written in C#

As of March 2021, Ryujinx has been tested on over 3,200 titles: ~2,700 boot past menus and into gameplay, with approximately 1,900 of those being considered playable. See the compatibility list here.

Usage

To run this emulator, we recommend that your PC have at least 8GB of RAM; less than this amount can result in unpredictable behavior and may cause crashes or unacceptable performance.

See our Setup & Configuration Guide on how to set up the emulator.

Latest build

These builds are compiled automatically for each commit on the master branch. While we strive to ensure optimal stability and performance prior to pushing an update, our automated builds may be unstable or completely broken.

The latest automatic build for Windows, macOS, and Linux can be found on the Official Website.

Building

If you wish to build the emulator yourself you will need to:

Step one: Install the X64 version of .NET 5.0 (or higher) SDK.

Step two (choose one):
(Variant one)

After the installation of the .NET SDK is done; go ahead and copy the Clone link from GitHub from here (via Clone or Download --> Copy HTTPS Link. You can Git Clone the repo by using Git Bash or Git CMD.

(Variant two):

Download the ZIP Tarball. Then extract it to a directory of your choice.

Step three:

Build the App using a Command prompt in the project directory. You can quickly access it by holding shift in explorer (in the Ryujinx directory) then right clicking, and typing the following command:
Run dotnet build -c Release inside the Ryujinx project folder to build Ryujinx binaries.

Ryujinx system files are stored in the Ryujinx folder. This folder is located in the user folder, which can be accessed by clicking Open Ryujinx Folder under the File menu in the GUI.

Features

  • Audio

    Audio output is entirely supported, audio input (microphone) isn't supported. We use C# wrappers for OpenAL, and libsoundio as the fallback.

  • CPU

    The CPU emulator, ARMeilleure, emulates an ARMv8 CPU and currently has support for most 64-bit ARMv8 and some of the ARMv7 (and older) instructions, including partial 32-bit support. It translates the ARM code to a custom IR, performs a few optimizations, and turns that into x86 code.
    Ryujinx also features an optional Profiled Persistent Translation Cache, which essentially caches translated functions so that they do not need to be translated every time the game loads. The net result is a significant reduction in load times (the amount of time between launching a game and arriving at the title screen) for nearly every game. NOTE: this feature is now enabled by default in the Options menu > System tab. You must launch the game at least twice to the title screen or beyond before performance improvements are unlocked on the third launch! These improvements are permanent and do not require any extra launches going forward.

  • GPU

    The GPU emulator emulates the Switch's Maxwell GPU using the OpenGL API (version 4.5 minimum) through a custom build of OpenTK. There are currently four graphics enhancements available to the end user in Ryujinx: disk shader caching, resolution scaling, aspect ratio adjustment and anisotropic filtering. These enhancements can be adjusted or toggled as desired in the GUI.

  • Input

    We currently have support for keyboard, mouse, touch input, JoyCon input support emulated through the keyboard, and most controllers. Controller support varies by operating system, as outlined below.
    Windows: Xinput-compatible controllers are supported natively; other controllers can be supported with the help of Xinput wrappers such as x360ce.
    Linux: most modern controllers are supported.
    In either case, you can set up everything inside the input configuration menu.

  • DLC & Modifications

    Ryujinx is able to manage add-on content/downloadable content through the GUI. Mods (romfs, exefs, and runtime mods such as cheats) are also supported; the GUI contains a shortcut to open the respective mods folder for a particular game.

  • Configuration

    The emulator has settings for enabling or disabling some logging, remapping controllers, and more. You can configure all of them through the graphical interface or manually through the config file, Config.json, found in the user folder which can be accessed by clicking Open Ryujinx Folder under the File menu in the GUI.

Compatibility

You can check out the compatibility list here.

Don't hesitate to open a new issue if a game isn't already on there!

Help

If you are having problems launching homebrew or a particular game marked status-playable or status-ingame in our compatibility list, you can contact us through our Discord server. We'll take note of whatever is causing the app/game to not work, put it on the watch list and fix it at a later date.

If you need help with setting up Ryujinx, you can ask questions in the #support channel of our Discord server.
