* Protect savestates while the threaded software renderer is running (#1864)Jesse Talavera2024-01-07
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * First crack at ensuring the render thread doesn't touch GPU state while it's being serialized * Get rid of the semaphore wait * Add some extra fields into GPU3D's serialization * Oops, TempVertexBuffer is already serialized * Move vertex serialization into its own method * Lock the GPU3D state when rendering on the render thread or serializing it * Revert "Lock the GPU3D state when rendering on the render thread or serializing it" This reverts commit 2f49a551c13934b9dc815bbda67a45098f0482a7. * Add comments that describe the synchronization within GPU3D_Soft - I need to understand it before I can solve my actual problem - Now I do * Revert "Revert "Lock the GPU3D state when rendering on the render thread or serializing it"" This reverts commit 1977566a6d8671d72bd94ba4ebf832c3bf08933a. * Let's try locking the GPU3D state throughout NDS::RunFrame - Just to see what happens * Slim down the lock's scope * Narrow the lock's scope some more * Remove the lock entirely * Try protecting the GPU3D state with just a mutex - I'll clean this up once I know it works * Remove a duplicate method definition * Add a missing `noexcept` specifier * Remove an unused function * Cut some non-hardware state from `GPU3D`'s savestate * Assume that the next frame after loading a savestate won't be identical * Actually, it _is_ worth it * Don't serialize the clip matrix - It's recalculated anyway * Serialize `RenderPolygonRAM` as an array of indexes * Clean up some comments - I liked the dialogue style, but oh well * Try restarting the render thread instead of using the lock - Let's see what happens * Put the lock back * Fix some polygon and vertex indexes being saved incorrectly - Taking the difference between two pointers results in the number of elements, not the number of bytes * Remove `SoftRenderer::StateBusy` since it turns out we don't need it - The real synchronization was the friends we made along the way

* Make the initial 3D renderer configurable via `NDSArgs` (#1913)Jesse Talavera2023-12-15
| | | | | | | * Allow 3D renderers to be created without passing `GPU` to the constructor * Make the initial 3D renderer configurable via `NDSArgs` * Fix a compiler error
* Sprinkle `const` around where appropriate (#1909)Jesse Talavera2023-12-12
| | | | | | | | | * Sprinkle `const` around where appropriate - This will make it easier to use `NDS` objects in `const` contexts (e.g. `const` parameters or methods) * Remove the `const` qualifier on `DSi_DSP::DSPRead16` - MMIO reads can be non-pure, so this may not be `const` in the future
* hopefully reset all GPU3D attributes properlyRSDuck2023-12-08

* Clean up the 3D renderer for enhanced flexibility (#1895)Jesse Talavera-Greenberg2023-11-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Give `GPU2D::Unit` a virtual destructor - Undefined behavior avoided! * Add an `array2d` alias * Move various parts of `GPU2D::SoftRenderer` to `constexpr` - `SoftRenderer::MosaicTable` is now initialized at compile-time - Most of the `SoftRenderer::Color*` functions are now `constexpr` - The aforementioned functions are used with a constant value in at least one place, so they'll be at least partially computed at compile-time * Generalize `GLRenderer::PrepareCaptureFrame` - Declare it in the base `Renderer3D` class, but make it empty * Remove unneeded `virtual` specifiers * Store `Framebuffer`'s memory in `unique_ptr`s - Reduce the risk of leaks this way * Clean up how `GLCompositor` is initialized - Return it as an `std::optional` instead of a `std::unique_ptr` - Make `GLCompositor` movable - Replace `GLCompositor`'s plain arrays with `std::array` to simplify moving * Pass `GPU` to `GLCompositor`'s important functions instead of passing it to the constructor * Move `GLCompositor` to be a field within `GLRenderer` - Some methods were moved up and made `virtual` * Fix some linker errors * Set the renderer in the frontend * Remove unneeded `virtual` specifiers * Remove `RenderSettings` in favor of just exposing the relevant member variables * Update the frontend to accommodate the core changes * Add `constexpr` and `const` to places in the interpolator * Qualify references to `size_t` * Construct the `optional` directly instead of using `make_optional` - It makes the Linux build choke - I think it's because `GLCompositor`'s constructor is `private`
* Refactor `NDS` and `DSi` to be objects (#1893)Jesse Talavera-Greenberg2023-11-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * First crack at refactoring NDS and DSi into objects - Remove all global/`static` variables in `NDS` and related classes - Rely more on virtual dispatch when we need to pick methods at runtime - Pass `NDS&` or `DSi&` to its constituent components where necessary - Introduce some headers or move some definitions to break `#include` cycles * Refactor the frontend to accommodate the core's changes * Move up `SchedList`'s declaration - Move it to before the components are initialized so the `map`s inside are initialized - Fields in C++ are initialized in the order they're declared * Fix a crash when allocating memory * Fix JIT-free builds * Fix GDB-free builds * Fix Linux builds - Explicitly qualify some member types in NDS, since they share the same name as their classes * Remove an unnecessary template argument - This was causing the build to fail on macOS * Fix ARM and Android builds * Rename `Constants.h` to `MemConstants.h` * Add `NDS::IsRunning()` * Use an `#include` guard instead of `#pragma once`
* Move all core types into namespaces (#1886)Jesse Talavera-Greenberg2023-11-25
| | | | | | | | * Reorganize namespaces - Most types are now moved into the `melonDS` namespace - Only good chance to do this for a while, since a big refactor is next * Fix the build
* Refactor the GPU to be object-oriented (#1873)Jesse Talavera-Greenberg2023-11-09
| | | | | | | | | | | | | | | | | * Refactor GPU3D to be an object - Who has two thumbs and is the sworn enemy of global state? This guy! * Refactor GPU itself to be an object - Wow, it's used in a lot of places - Also introduce a new `Melon` namespace for a few classes - I expect other classes will be moved into `Melon` over time * Change signature of Renderer3D::SetRenderSettings - Make it noexcept, and its argument const * Remove some stray whitespace
* update copyright yearsArisotura2023-11-04

* Make the NDS teardown more robust (#1798)Jesse Talavera-Greenberg2023-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Make cleanup a little more robust to mitigate undefined behavior - Add some null checks before cleaning up the GPU3D renderer - Make sure that all deleted objects are null - Move cleanup logic out of an assert call - Note that deleting a null pointer is a no-op, so there's no need to check for null beforehand - Use RAII for GLCompositor instead of Init/DeInit methods * Replace a DeInit call that I missed * Make ARMJIT_Memory less likely to generate errors - Set FastMem7/9Start to nullptr at the end - Only close and unmap the file if it's initialized * Make Renderer3D manage its resources with RAII * Don't try to deallocate frontend resources that aren't loaded * Make ARMJIT_Memory::DeInit more robust on the Switch * Reset MemoryFile on Windows to INVALID_HANDLE_VALUE, not nullptr - There is a difference * Don't explicitly store a Valid state in GLCompositor or the 3D renderers - Instead, create them with static methods while making the actual constructors private * Make initialization of OpenGL resources fail if OpenGL isn't loaded * assert that OpenGL is loaded instead of returning failure

* Allow for a more modular renderer backends (#990)Wunk2021-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * Draft GPU3D renderer modularization * Update sources C++ standard to C++17 The top-level `CMakeLists.txt` is already using the C++17 standard. * Move GLCompositor into class type Some other misc fixes to push towards better modularity * Make renderer-implementation types move-only These types are going to be holding onto handles of GPU-side resources and shouldn't ever be copied around. * Fix OSX: Remove 'register' storage class specifier `register` has been removed in C++17... But this keyword hasn't done anything in years anyways. OSX builds consider this "warning" an error and it stops the whole build. * Add RestartFrame to Renderer3D interface * Move Accelerated property to Renderer3D interface There are points in the code base where we do: `renderer != 0` to know if we are feeding an openGL renderer. Rather than that we can instead just have this be a property of the renderer itself. With this pattern a renderer can just say how it wants its data to come in rather than have everyone know that they're talking to an OpenGL renderer. * Remove Accelerated flag from GPU * Move 2D_Soft interface in separate header Also make the current 2D engine an "owned" unique_ptr. * Update alignment attribute to standard alignas Uses standardized `alignas` rather than compiler-specific attributes. https://en.cppreference.com/w/cpp/language/alignas * Fix Clang: alignas specifier Alignment must be specified before the array to align the entire array. https://en.cppreference.com/w/cpp/language/alignas * Converted Renderer3D Accelerated to variable This flag is checked a lot during scanline rasterization. So rather than having an expensive vtable-lookup call during mainline rendering code, it is now a public constant bool type that is written to only once during Renderer3D initialization.
