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

As discussed in KhronosGroup#5084, the default branch of this repository is now 'main'. This change should be largely transparent to repository users, since github rewrites many references to the old 'master' branch to 'main'. However, if you have a checked-out local clone, you may wish to take the following steps as recommended by github:

git branch -m master main
git fetch origin
git branch -u origin/main main
git remote set-head origin -a

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.

This repository contains both the Validation Layers source as well as Tests for them.

Updates to the Vulkan-ValidationLayers repository which correspond to a new Vulkan specification release are tagged using the following format: v<version> (e.g., v1.1.96).

Note: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the sdk-<version>.<patch> format (e.g., sdk-1.1.92.0).

This scheme was adopted following the 1.1.96 Vulkan specification release.
