Vulkan Ecosystem Components

This project provides the Khronos official Vulkan ICD desktop loader and the Vulkan validation layers for Windows, Linux, Android, and MacOS.

Vulkan is an Explicit API, enabling direct control over how GPUs actually work. By design, minimal error checking is done inside a Vulkan driver. Applications have full control and responsibility for correct operation. Any errors in how Vulkan is used can result in a crash. This project provides Vulkan validation layers that can be enabled to assist development by enabling developers to verify their applications correct use of the Vulkan API.

Vulkan supports multiple GPUs and multiple global contexts (VkInstance). The ICD loader is necessary to support multiple GPUs and VkInstance-level Vulkan commands. Additionally, the loader manages inserting Vulkan layer libraries such as validation layers between the application and the ICD.

The following components are available in this repository:
