…ex for cross-GPU shader rendering Add DXGI shared texture support and keyed mutex synchronization to enable shader-based rendering across dGPU and iGPU. Shader bytecode can be loaded at runtime via a controller pipe and toggled on/off via pipe commands. Routing of shader execution is controlled by igpu-shader XML setting, allowing iGPU to render on the shared texture when enabled. ### Summary Introduce DXGI shared texture resources and mutex-based synchronization to perform GPU shader rendering on a shared target without RAM copies. Shader bytecode can be uploaded through a pipe channel and executed in a GPU-resident path. ### Details - Add shared texture, keyed mutex, SRV/RTV and shader state to Direct3DDevice - Implement pipe commands: loadshader, shader_enable, shader_disable; store shader bytecode in driver memory - Read igpu-shader from vdd_settings.xml and route shader path to iGPU or dGPU - Integrate shader execution into SwapChainProcessor using keyed mutex coordination - Ensure textures are created with D3D11_RESOURCE_MISC_SHARED | D3D11_RESOURCE_MISC_SHARED_KEYEDMUTEX - No host RAM copies; all shader operations stay on GPU; minimal impact on existing DXGI flow

@ReenigneArcher My "Git-Fu" needs improvements... as do most of my actual coding, that is why I went with remarking any code changes. Due to lack of time, I've left this in this manner. In the hope that someone with more skill with implementing shaders, swapchains and share memory between gpus could take a look at it. Ps. I hope to have time to get back to Swedish translation on your software, when things calm down in my personal life. |

Remarked "Shader logic" and example files, AI-help
Here is the code, including using iGPU for shader calcs. I also included 3 shaders, one simple vortex, one framebuffer timed pixel shader and a advanced combine shader. I have not tested it yet, have a bunch of feature still missing or that i want to implement. But due to lack of sleep I've chose to share the foundation, since I'm now don't remember if the code for drawing the shader was added or not. More eyes on it would be good.
Files that are in focus,
All other "bits in the PR" is temporary files and agent bloat.
Every added bit of logic and comments are commented this way: // #--- followed by logic or "// #--- // " if it was an remark. So in order to test the code with a compile you only remove "// #--- " from all lines that has that in the beginning. That's the three files mentioned above.
