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.
Adds support for InfoType::SystemResourceSize (0x1C) which is required for
proper initialization of the Virtual Address Memory Manager (VAMM). This
implementation:
1. Adds SystemResourceSize to the InfoType enum in svc_types.h
2. Implements the GetInfo handler for SystemResourceSize in svc_info.cpp
3. Returns 512MB (0x20000000 bytes) as the system resource size
4. Adds debug logging for the SVC call
The 512MB value is chosen based on typical system resource allocations
needed for VAMM initialization on the Nintendo Switch.
This fixes crashes in games that rely on VAMM functionality, particularly
during nn::os::detail::VammManager::InitializeIfEnabled().
Updated the ssl stubs to implement ssl:s for Firmware 19
This should make Xenoblade X: Definitive Edition bootable
