* Introduce Jit32 and JitCore32 objects
* Initialize JIT when launching 32bit executables
* Introduce kernel objects for 32bit processes
This commit introduces two new kernel thread types, `KNceThread` and `Jit32Thread`.
`KNceThread`s behave like the previous kernel thread object by setting up thread state and jumping into guest code.
`KJit32Thread`s need to run guest code on a `JitCore32` object, so they perform the necessary state setup and then they also setup the jit core for executing guest code. A loop was introduced because jit execution might return when halted, either for an SVC or for preemption. In those cases the thread needs to wait to be scheduled before executing again.
The process object has also been updated to be able to create 32bit threads when running 32bit processes.
Additionally NCE's ThreadContext has been removed from DeviceState, since a thread is not an NCE thread only anymore, and IPC code has been changed to retrieve the tls region from the thread object.
* Introduce a preemption handler for scheduling with JIT
Scheduler initialization has been delayed until process information is available, as it needs to differentiate between 32bit and 64bit processes.
* Support initializing VMM for 32bit address spaces
* Implement GetThreadContext3 SVC for 32bit processes
* Introduce a thread local pointer to the current guest thread
This also gives easier access to the current guest process structure via the thread structure, just like any kernel does for their internal structures.
* Add a signal handler for JIT threads
* Implement coprocessor 15 accesses
* Implement exclusive memory writes and exclusive monitor
* Enable JIT fastmem
* Enable more JIT optimizations and log exceptions
* Fix incorrect logging call in QueryMemory
* Translate guest virtual addresses on direct accesses from SVCs
* Perform TLS page address translation for direct accesses
This allows the IPC code to work without modifications since `KThread::tlsRegion` now stores a host address that can be accessed directly.
* Add Dynarmic as a submodule
* Revert "Perform TLS page address translation for direct accesses"
This reverts commit 2e25b3f7e4f0687b038fa949648c74e3393da006.
* Revert "Translate guest virtual addresses on direct accesses from SVCs"

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.
NCE is implicitly depended on by the `GPU` class due to the NCE Memory Trapping API so the destruction of it must take place after the destruction of the `GPU` class. Additionally, to prevent bugs the NCE destructor must set `staticNce` to `nullptr` as the signal handler will potentially access a destroyed instance of NCE otherwise.
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.
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.

* Improve `GetFunctionStackTrace` logs when `dli_sname` or `dli_fname` are missing
* Support more RT Formats
Support for subpasses was added by reworking attachment reuse code to account for preserved attachments and subpass dependencies. A lot of RT formats were also added to allow SMO to boot up entirely, it should be noted that it doesn't render anything.
`FenceCycle` had a cyclic dependency which broke clean exit, we now utilize `std::weak_ptr<FenceCycle>` inside the `Texture` object. A minor fix for broken stack traces was also made caused by supplying a `nullptr` C-string to libfmt when a symbol was unresolved which caused an `abort` due to invocation of `strlen` with it.
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.
Support for the following parameters was added to `QueueBuffer`:
* Earliest Present Timestamp
* Swap Interval
* Crop
* Scaling Mode
* Transform
* Frame ID (Not returned to guest yet)
We utilize ANativeWindow APIs directly to achieve all of this in an efficient manner since HWC will be used directly for it, we do plan to introduce Vulkan equivalents for all of these operations later down the line for a port to non-Android platforms.
This commit reworks the `Texture` class to include a Vulkan Image backing that can be optionally owning or non-owning and swapped in with consideration for Vulkan image layout, it also adds CPU-sided synchronization for the texture objects with FenceCycle. It also makes the appropriate changes to `PresentationEngine` and `GraphicBufferProducer` to work with the new `Texture` class while setting the groundwork for supporting swapchain recreation. It also fixes a log in `IpcResponse` and improves the display mode selection algorithm by further weighing refresh rate.
This commit makes GraphicBufferProducer significantly more accurate by matching the behavior of AOSP alongside mirroring the tweaks made by Nintendo.
It eliminates a lot of the magic structures and enumerations used prior and replaces them with the correct values from AOSP or HOS.
There was a lot of functional inaccuracy as well which was fixed, we emulate the exact subset of HOS behavior that we need to. A lot of the intermediate layers such as GraphicBufferConsumer or Gralloc/Sync are not emulated as they're pointless abstractions here.
We decided to restructure Skyline to draw a layer of separation between guest and host GPU. We're reserving the `gpu` namespace and directory for purely host GPU and creating a new `soc` directory and namespace for emulation of parts of the X1 SoC which is currently limited to guest GPU but will be expanded to contain components like the audio DSP down the line.
Add Tracing for SVCs, Services, NVDRV, and Synchronization Primitives. In addition, fix `TRACE_EVENT_END("guest")` being emitted when a signal is received while being in the guest rather than host which would cause an exception. This commit also disables warnings for the Perfetto library as we do not control fixing them.
This reimplements our time backend to be significantly more accurate to
the real PSC and provides complete implementations for every time IPC
allowing many newer games to work properly.
Time is unique in its use of glue services, the core sysmodule is fully
isolated and doesn't interface with any other services. Glue is instead
used where that is needed (e.g. for fetching settings), this distinction
is also present in our implementation.
Another unique feature of time is its global state, as time is
calibrated from the start of the service its state cannot be lost as
that would result in the application offsetting time incorrectly
whenever it closed a session.
A large proportion of this is based off of Thog's 9.0.0 PSC reversing.
This addresses all CR comments including more codebase-wide changes arising from certain review comments like proper usage of its/it's and consistent contraction of it is into it's.
An overhaul was made to the presentation and formatting of `KThread.h` and `LoadBalance` works has been superseded by `GetOptimalCoreForThread` which can be used alongside `InsertThread` or `MigrateToCore`. It makes the API far more atomic and neater. This was a major point of contention for the design prior, it's simplified some code and potentially improved performance.
We've moved to using RS and GS from ASCII as delimiters rather than
'\n' and '|', this allows more robust parsing and increases the
readability of the log files
An exceptional signal handler allows us to convert an OS signal into a C++ exception, this allows us to alleviate a lot of crashes that would otherwise occur from signals being thrown during execution of games and be able to handle them gracefully.
