Thank you to Ryujinx (riperiperi specifically) for the pointer towards clip distances
Huge thanks to crueter for finding where the code works and Camille for giving pointers along the way.
Enhances the Vulkan memory allocator with better OOM handling and memory
alignment:
* Add memory recovery by cleaning up empty allocations before failing
* Implement proper fallback to non-device-local memory
* Simplify memory alignment handling for different vendors
* Add better error logging for allocation failures
* Add IsEmpty() helper to track unused allocations
* Fix alignment requirements for Adreno (4KB) vs other vendors
These changes improve the robustness of memory allocation, particularly
in low-memory situations, and streamline vendor-specific alignment
requirements.
Add workarounds for Samsung Xclipse GPUs:
- Disable extendedDynamicState3ColorBlendEquation as it is broken in Samsung
drivers, similar to AMD drivers
- Add Samsung's proprietary driver to the validated driver list for clock
boosting
- Fix log message to indicate both AMD and Samsung drivers have broken
color blend equation support
Remove stray logical OR operator from validated_driver condition.
- Added missing <thread> header for std::thread usage
- Added <fcntl.h> for O_CLOEXEC and O_NONBLOCK definitions
- Fixed struct initialization order in uffdio_copy to match declaration order

This commit adds Windows-specific implementation of the fault-managed memory
system, providing similar functionality to the existing Linux/Android implementation.
Key changes:
- Added Windows-specific memory management using VirtualAlloc/VirtualFree
- Implemented Windows vectored exception handler for page fault handling
- Added proper memory protection and page fault handling on Windows
- Updated memory snapshot functionality to work on Windows
- Added proper cleanup of Windows-specific resources
- Fixed type conversion issues in memory management code
- Added proper error handling for Windows memory operations
- Fixed VRAM Memory Layout Mode to allow up to 12Gb
The implementation uses Windows-specific APIs:
- VirtualAlloc/VirtualFree for memory management
- AddVectoredExceptionHandler for page fault handling
- VirtualProtect for memory protection management
This change maintains feature parity with the Linux/Android implementation
while using Windows-native APIs for better performance and reliability.

Adds a new cross-platform memory management system with enhanced capabilities:
- Fault-managed memory allocation for Linux/Android platforms
- Memory snapshot and differential snapshot support
- Predictive memory reuse tracking for optimized access patterns
- Vulkan compute buffer integration
- User-configurable settings for enabling features
The system integrates with the existing Vulkan renderer to provide more
efficient memory handling, especially for compute-intensive workloads.

Implement a robust asynchronous shader compilation system inspired by commit
1fd5fefcb1. This enhancement provides:
- True multi-threaded shader compilation with atomic status tracking
- Persistent disk caching for faster shader loading
- Command queue system for background processing
- Integration with Citron's scheduler for better resource management
- Parallel shader loading to reduce startup times
- Improved error handling and recovery mechanisms
These changes significantly reduce shader compilation stuttering and improve
overall performance when using asynchronous shaders. The implementation
maintains compatibility with Citron's existing architecture while adding
more robust threading capabilities.

This commit adds improved Vulkan functionality to the Citron emulator:
- Add thread-safe texture management with automatic error recovery
- Implement shader caching with validation support
- Add robust error handling for Vulkan operations
- Implement platform-specific initialization for Windows, Linux, and Android
These enhancements improve stability when handling texture loading errors
and provide better recovery mechanisms for Vulkan failures.

The functionality acts much more like a real-time downscale since the FSR1 used by Yuzu is not compatible with a real interpolation and is just upscale and downscale.
Refactors and improves the texture format conversion system in the Vulkan
renderer:
- Adds proper sRGB to linear conversion for depth formats
- Improves shader accuracy for ABGR8 SRGB to D24S8 conversion
- Adds gamma correction and proper depth range clamping
- Moves GetSupportedFormat implementation to header
- Cleans up format conversion switch statement
- Removes redundant format conversion paths
The changes improve accuracy when converting between color and depth
formats, particularly for sRGB sources. The shader improvements ensure
proper gamma correction and depth range handling.
Technical changes:
- Improves sRGB to linear conversion in fragment shader
- Adds proper depth value clamping
- Consolidates format conversion logic
- Removes duplicate GetSupportedFormat implementation
Adds several new shader-based format conversion pipelines to support additional
texture formats and operations:
- RGBA8 to BGRA8 conversion
- YUV420/RGB conversions
- BC7 to RGBA8 decompression
- ASTC HDR to RGBA16F decompression
- RGBA16F to RGBA8 conversion
- Temporal dithering
- Dynamic resolution scaling
Updates the texture cache runtime to handle these new conversion paths and adds
helper functions to check format compatibility for dithering and scaling
operations.
The changes include:
- New shader files and CMake entries
- Additional conversion pipeline setup in BlitImageHelper
- Extended format conversion logic in TextureCacheRuntime
- New format compatibility check helpers
Implements conversion from sRGB color formats to D24S8 depth-stencil format
in the Vulkan renderer. This change includes:
- New fragment shader convert_abgr8_srgb_to_d24s8.frag that handles proper
sRGB to linear conversion before depth calculation
- Added shader to CMake build system
- Extended BlitImageHelper with new conversion pipeline and methods
- Updated texture cache to handle sRGB to D24S8 format conversion paths
The conversion properly handles sRGB color space by first converting to
linear space before calculating luminance values for the depth component,
while preserving alpha channel data for the stencil component.
- Modify DmaPusher to use safe memory reads when handling compute
operations at High GPU accuracy
- Prevent potential memory corruption issues that could lead to
invalid dispatch parameters
- Previously, unsafe reads could result in corrupted launch_description
data in KeplerCompute::ProcessLaunch, causing invalid vkCmdDispatch
calls
- By enforcing safe reads specifically for compute operations, we
maintain performance for other GPU tasks while ensuring compute
dispatch stability
This change requires >= High GPU accuracy level to take effect.
