Implements a cache for storing `VkPipeline` objects which are fairly expensive to create and doing so on a per-frame basis was rather wasteful and consumed a significant part of frametime. It should be noted that this is **not** compliant with the Vulkan specification and **will** break unless the driver supports a relaxed version of the Vulkan specification's Render Pass Compatibility clause.
Mostly based off of yuzu's implementation, this will need to be extended in the future to open up a UI for configuring controllers according to the applications requirements.
Skyline's `exception` class now stores a list of all stack frames during the invocation of the exception. These can later be parsed by the exception handler to generate a human-readable stack trace. To assist with more complete stack traces, `-fno-omit-frame-pointer` is now passed on debug builds which forces the inclusion of frames on function calls.
The DMA engine is used to perform DMA buffer/texture copies directly on the GPU. It can deswizzle arbritary regions of input textures, perform component remapping and swizzle into output textures.
This impl only supports 1D buffer copies, 2D ones will come later.
The Kepler compute engine is used to run compute jobs encapsulated in to QMDs on the GPU, this commit doesn't implement compute itself but adds the register and QMD structs that will be needed for it in the future.
Quirk terminology was deemed to be inappropriate for describing the features/extensions of a device. It has been replaced with traits which is far more fitting but quirks will be used as a terminology for errata in devices.
Fermi2D supports macros in addition to Maxwell3D, these both share code memory. To support this we rework the macro interpreter to support passing in a target engine and abstract the communications out into an interface that can be implemented by applicable engines.

The Buffer Manager handles mapping of guest buffers to host buffer views with automatic handling of sub-buffers and eventually supporting recreation of overlapping buffers to create a single larger buffer.
Implements infrastructure for using guest buffers on the host for rendering, a `BufferManager` is still missing which'd handle mapping from guest buffers to host buffers and will be subsequently committed. It should be noted that `BufferView` is also disconnected from `Buffer` and shared for every instance with the same properties like `TextureView` is now.
This class will be entirely responsible for any interop with the shader compiler, it is also responsible for caching and compilation of shaders in itself.
We want to utilize features from C++ 20 ranges but they haven't been entirely implemented in libc++ so in the meantime we use the reference implementation for it which is Ranges v3.
Maxwell3D Registers weren't initialized to the correct values prior, this commit fixes that by doing `HandleMethod` calls with all the register values being initialized. This is in contrast to the registers being set without calling the methods in `GraphicsContext` or otherwise resulting in bugs.
We require a way to track certain host GPU features that are optional such as Vulkan extensions, this is what the `QuirkManager` class does as it checks for all quirks and holds them allowing other components to branch based off these quirks.
A thread local LoggerContext is now used to hold the output file stream instead of the `Logger` class. Before doing any logging operations, a LoggerContext must be initialized.
This commit will not build successfully on purpose.
The Host1x block of the TX1 supports 14 separate channels to which commands can be issued, these all run asynchronously so are emulated the same way as GPU channels with one FIFO emulation thread each. The command FIFO itself is very similar to the GPFIFO found in the GPU however there are some differences, mainly the introduction of classes (similar to engines) and the Mask opcode (which allows writing to a specific set of offsets much more efficiently).
There is an internal Host1x class which functions similar to the GPFIFO class in the GPU, handling general operations such as syncpoint waits, this is accessed via the simple method interface. Other channels such as NVDEC and VIC are behind the 'Tegra Host Interface' (THI) in HW, this abstracts out the classes internal details and provides a uniform method interface ontop of the Host1x method one. We emulate the THI as a templated wrapper for the underlying class.
Syncpoint increments in Host1x are different to GPU, the THI allows submitting increment requests that will be queued up and only be applied after a specific condition in the associated engine is met; however the option to for immediate increments is also available.
host1x channels are generally similar to GPU channels however there is only one channel for each specific class (like a GPU engine) and an address space is shared between them all.
This PR implements the simple IOCTLs with the larger ones that will depend on changes outside of nvdrv being left for future commits. This is enough to partly run oss-nvjpeg.
To offset some of the performance overhead of using debug builds, we now optimize all libraries using `-Ofast` while building Skyline itself with `-O0`.
The version of libcxx shipped with Android NDK is fairly outdated and doesn't contain several features we desire such as C++ 20 ranges. This has been fixed by using libcxx directly from the LLVM Project which has been added as a submodule and can be updated independently of NDK.
We've moved to using a beta AGP as `7.0.2` is breaks `clangd` and other C++ features on Beta/Canary Android Studio. NDK was additionally updated with `mbedtls` to fix warnings caused by it alongside some other minor fixes to code for newer versions of libcxx.
The new AGP has a bug where it does not look for executables specified in `android_gradle_build.json` in `PATH` that includes `ninja` which is provided by the `ninja-build` package on the system rather than Android SDK's CMake on GitHub Actions (Ubuntu 20.04). This has been fixed by symlinking `/usr/bin/ninja` to the project root which is searched in for the `ninja` executable.
Library headers would produce errors that are out of our control and as a result of that, we just want to ignore this. This is possible by including the offending headers as system headers, compilers don't emit any warnings arising from them. This was extended to all libraries rather than just those which currently emitted warnings for consistency's sake.

Allows the execution of multiple channels at the same time, with locking
being performed on the host GPU scheduler layer, address spaces can be
bound to one or more channels.
This commit introduces the `CommandExecutor` which is responsible for creating and orchestrating a Vulkan command graph comprising of `CommandNode`s that construct all the objects required for rendering. As a result of the infrastructure provided by `CommandExecutor`, `ClearBuffers` could be implemented and be appropriately utilized.
A bug regarding scissors was also determined and fixed in the PR, the extent of them were previously inaccurate and this has now been fixed.
Note: We don't synchronize any textures from the guest for now as this would override the contents on the host, this'll be fixed with the appropriate write tracking but it also results in a black screen for anything that writes to FB
This commit implements a filter by type for any validation layer output, this allows filtering out any logs which may be unnecessary and additionally triggering a breakpoint as required.
An issue concerning the `NDEBUG` flag never being set was fixed, it's now supplied as a release compiler flag. The issue can manifest itself by always relying on a validation layer even though it shouldn't on release, this is why the validation layer was mistakenly disabled entirely previously by using `#ifndef` rather than `#ifdef`.
An issue with the initial layout of a texture being supplied as neither `VK_IMAGE_LAYOUT_UNDEFINED` or `VK_IMAGE_LAYOUT_PREINITIALIZED` was fixed, these cases are now handled by transitioning to those layouts after creating the image rather than supplying it within `initialLayout`.
Another issue was fixed regarding not maintaining a transformation after a surface has been destroyed and recreated existed and manifested itself when the user would go out of the app and come back in, they would see the surface having an identity transformation rather than the desired one.
Fixes bugs with the Texture Manager lookup, fixes `RenderTarget` address extraction (`low`/`high` were flipped prior), refactors `Maxwell3D::CallMethod` to utilize a case for the register being modified + preventing redundant method calls when no new value is being written to the register, and fixes the behavior of shadow RAM which was broken previously and would lead to incorrect arguments being utilized for methods.
Implement the groundwork for the texture manager to be able to report basic overlaps and be extended to support more in the future. The Maxwell3D registers `RenderTargetControl`, `RenderTarget` and a stub for `ClearBuffers` were implemented.
A lot of changes were also made to `GuestTexture`/`Texture` for supporting mipmapping and multiple array layers alongside significant architectural changes to `GuestTexture` effectively disconnecting it from `Texture` with it no longer being a parent rather an object that can be used to create a `Texture` object.
Note: Support for fragmented CPU mappings hasn't been added for texture synchronization yet
Utilize Boost Container's `small_vector` for optimizing allocations, fix certain implicit casting issues and make `ILogger` not output an additional newline in the log when the application supplies one at the end of the log
Implements the 'csrng:' service using C++ <random>'s Mersenne Twister, this does make it insecure for cryptographic purposes but it is pointless to attempt to do this regardless as we cannot ensure that the guest will run in a secure environment which cannot be mutated by an attacker. Used by Prison Princess, Pokemon Cafe Mix, Paint your Pet and more.
We've moved from using an AAR for Mbed TLS to a submodule as the AAR was packaged manually and used from a local repository which ended up being very hacky and resulted in Linter errors, it could also not be updated with ease as it would need to be repackaged. All of these issues have been solved by moving to a git submodule tied to the official Mbed TLS GitHub repository.
VI/IHOSBinder suffered from major inaccuracies in their function due to being quickly thrown together initially with little concern for accuracy, this has now been fixed with them being substantially more accurate now.
