SelectPhysicalDevice took the first device exposing a graphics+present
queue. On hybrid-graphics laptops that is the integrated GPU, so the
discrete card went unused - and AMD's integrated driver access-violates
inside vkCreateGraphicsPipelines while compiling some translated guest
shaders, killing the process. The CLR surfaced that native AV as
"Invalid Program: attempted to call a UnmanagedCallersOnly method from
managed code", which made it look like a CPU/threading fault.
Score the candidates instead: NVIDIA parts win, other discrete GPUs come
next, and an integrated GPU is only chosen when nothing else can present.
SHARPEMU_VK_DEVICE=<substring> pins a specific adapter, and the selected
device is logged.
- Enable VertexPipelineStoresAndAtomics/FragmentStoresAndAtomics:
fixes vkCreateGraphicsPipelines() rejecting guestBuffers storage
descriptor as NonWritable in vertex/fragment stages.
- Enable ShaderInt64: fixes vkCreateShaderModule() rejecting SPIR-V
using 64-bit integer capability.
- Query GetPhysicalDeviceFeatures first and only enable what the GPU
actually reports as supported, with a warning fallback otherwise.
Also adds optional Vulkan Validation Layers (SHARPEMU_VK_VALIDATION=1)
to surface these VUID errors during development instead of silent
VK_ERROR_DEVICE_LOST.
* [shader-decoder-part1] Implemented a shader decoder for Gen5 shaders, including IR generation, metadata reading, scalar evaluation, and SPIR-V translation. Updated related exports and video output components to support the new shader decoding functionality.
* [shader decoder] correct RDNA2 operands, fixing synchronization problems
* [shader-decoder] RDNA2 decoder improvements
* [shader-decoder] fix RDNA2 shift masking and sprite draws
* [shader-decoder] improve RDNA2 shader decoder to support more instructions and fix some issues with the previous implementation.
