# Vulkan API Headers
|
||||
|
||||
仓库包含Vulkan API 和 API 注册表。Vulkan 是一个适用于高性能 3D 图形设备的低开销、跨平台 API。与 OpenGL ES (GLES) 一样，Vulkan 提供用于在应用中创建高品质实时图形的工具。与OpenGL ES相比使用 Vulkan 的优势明显，Vulkan可以大大降低 CPU 开销，另外Vulkan支持 SPIR-V 二进制Shader语言。
|
||||
|
||||
OpenHarmony引入后，在框架层新增加载程序（Vulkan-Loader），负责加GPU驱动实现、加载OpenHarmony平台的Vulkan WSI(Window System Integration, 窗口系统集成)实现，并对外开放Vulkan API。请参考[Vulkan-Loader](https://gitee.com/openharmony/third_party_vulkan-loader/blob/master/README_OpenHarmony.md)
|
||||
|
||||
|
||||
## 南向开发和OpenHarmony发行版
|
||||
|
||||
设备成功运行Vulkan必需的条件：
|
||||
1. Vulkan-Loader，由OpenHarmony提供
|
||||
2. 实现了Vulkan API 的 VulKan 驱动程序，由 SoC 提供。
|
||||
|
||||
### Vulkan Loader
|
||||
|
||||
`third_party/vulkan-loader`中实现的Vulkan加载程序是Vulkan应用与Vulkan驱动之前的Wrapper层。安装在`/system/lib[64]/libvulkan.so`中。
|
||||
Vulkan Loader 会提供标准 Vulkan API 函数符号、OpenHarmony WSI扩展的函数符号，以及许多其他可选扩展。
|
||||
|
||||
|
||||
### Vulkan 驱动程序
|
||||
|
||||
Vulkan-Loader成功加载Vulkan驱动程序的必要条件
|
||||
1.要参考[LoaderDriverInterface](https://gitee.com/openharmony/third_party_vulkan-loader/blob/master/docs/LoaderDriverInterface.md)实现对应的接口;
|
||||
2.提供驱动程序描述json文件，参考[加载GPU驱动](https://gitee.com/openharmony/third_party_vulkan-loader/blob/master/README_OpenHarmony.md#%E5%8A%A0%E8%BD%BDgpu%E9%A9%B1%E5%8A%A8);
|
||||
3.实现OpenHarmony平台的扩展包括`VK_OHOS_native_buffer`和`VK_OpenHarmony_external_memory_OHOS_native_buffer`扩展。
|
||||
|
||||
|
||||
## 北向应用开发者
|
||||
|
||||
### VK_OpenHarmony_OHOS_surface 扩展
|
||||
|
||||
接口：vkCreateOHOSSurfaceOpenHarmony
|
||||
VkResult vkCreateOHOSSurfaceOpenHarmony(
|
||||
VkInstance instance,
|
||||
const VkOHOSSurfaceCreateInfoOpenHarmony pCreateInfo,
|
||||
const VkAllocationCallbacks pAllocator,
|
||||
VkSurfaceKHR pSurface)
|
||||
|
||||
参数：
|
||||
instance是要关联Surface的实例。
|
||||
pCreateInfo是一个指向结构的指针，该VkOHOSSurfaceCreateInfoOpenHarmony 结构包含影响表面对象创建的参数。
|
||||
pAllocator是用于在没有更多特定内存分配器可用时做为Surface对象分配的分配器。
|
||||
pSurface是一个指向VkSurfaceKHR句柄的指针，在该句柄中返回创建的Surface对象。

# Vulkan API Headers

|
||||
|
||||
OpenHarmony引入后，在框架层新增Vulkan Wrapper，负责实现Vulkan WSI(Window System Integration, 窗口系统集成) 与本地窗口(NativeWindow)对接，另外提供Vulkan加载程序。目前仅支持native层调用Vulkan。
|
||||
|
||||
|
||||
## 一、北向开发和OpenHarmony发行版
|
||||
### 1.实现 Vulkan
|
||||
|
||||

|
||||
1. 加载程序，由OpenHarmony提供
|
||||
2. 实现了Vulkan API 的 VulKan 驱动程序，有 SoC 提供。
|
||||
|
||||
### 2. Vulkan Wrapper
|
||||
|
||||
`foundation/graphic/graphic_2d/frameworks/vulkan_wrapper`中实现的Vulkan加载程序是Vulkan应用与Vulkan驱动之前的Wrapper层。Vulkan Wrapper安装在`/system/lib[64]/libvulkan.so`中。Vulkan Wrapper 会提供标准 Vulkan API 函数符号、OpenHarmony WSI扩展的函数符号，以及许多其他可选扩展。
|
||||
|
||||
|
||||
### 3. Vulkan 驱动程序
|
||||
|
||||
Vulkan驱动程序需要对外暴露的函数符号请参考`hdi_vulkan.h`中的定义。
|
||||
|
||||
## 二、南向应用开发者
|
||||
|
||||
### VK_OpenHarmony_OHOS_surface 扩展
|
||||
|
||||

|
||||

|
||||
const VkOHOSSurfaceCreateInfoOpenHarmony pCreateInfo,
|
||||

|
||||
VkSurfaceKHR pSurface)
|
||||
|
||||
参数：
|
||||
instance是要关联Surface的实例。
|
||||
pCreateInfo是一个指向结构的指针，该VkOHOSSurfaceCreateInfoOpenHarmony 结构包含影响表面对象创建的参数。
|
