This project provides the Khronos offical Vulkan SC validation layers.
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.
Before submitting an issue to the validation layers or reaching out to the developers it may be prudent to reach out to the community first. These resources can be helpful to refine your issue, work out an application/driver bug, etc.

Vulkan SC is an API derived from Vulkan with various changes applied to fulfill the special requirements of safety critical applications. The Vulkan SC API has a large overlap with Vulkan. As such, we endeavor to leverage as many of the Vulkan Ecosystem components as possible.
This repository contains the Vulkan SC Validation Layers which is intended for development environments, and is not expected to be used in production (safety) environments.
NOTE: This repository is a downstream fork of KhronosGroup/Vulkan-ValidationLayers which is periodically rebased.
This repository continues to have functioning Vulkan validation layers with equivalent functionality to the upstream branch point.
The choice of Vulkan or Vulkan SC support is determined at build time.

Updates to this repository which correspond to a new Vulkan specification release are tagged using the following format: v<version> (e.g., v1.3.266).
Note: Marked version releases have undergone thorough testing but do not imply the same quality level as SDK tags. SDK tags follow the vulkan-sdk-<version>.<patch> format (e.g., vulkan-sdk-1.3.266.0).
This scheme was adopted following the 1.3.266 Vulkan specification release.
Weekly automated (and untested) tags are generated with the following format: snapshot-<year>wk<week-number>, eg. snapshot-2024wk06.
For Vulkan SC, updates to a new API version will be tagged using the following format vksc<version>.<patch> (e.g., vksc1.0.12).

While this project has been developed primarily by LunarG, Inc., there are many other companies and individuals making this possible: Valve Corporation, funding project development; Google providing significant contributions to the validation layers; Khronos providing oversight and hosting of the project.
