# RHIDevice::CreatePipelineState

```cpp
virtual RHIPipelineState* CreatePipelineState(const PipelineStateDesc& desc) = 0;
```

创建渲染管线状态对象（PSO）。

**参数：**
- `desc` - 管线状态描述符，包含编译好的着色器字节码

**返回：** 新创建的管线状态指针，失败返回 `nullptr`

**复杂度：** O(1)

**示例：**

```cpp
PipelineStateDesc psoDesc;
psoDesc.pBlob = compiledShaderBytecode;
psoDesc.size = bytecodeSize;

RHIPipelineState* pipelineState = device->CreatePipelineState(psoDesc);
```
