Vulkan and Vulkan SC Ecosystem Components

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

CI Build Status

Introduction

Vulkan

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.

The Vulkan-ValidationLayer repository contains the official Vulkan validation layers that are used for Linux, Windows, MacOS, and iOS.

Vulkan SC

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

The following components are available in this repository:

• Validation Layers
• Tests

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.

The sc_main branch is currently based on the sdk-1.2.198 Vulkan-ValidationLayers tag and contains Vulkan SC modifications to support the Vulkan SC 1.0 API.

• Daniel Koch for Vulkan SC-specific concerns.

General validation issues these should be reported to the upstream repository:

• KhronosGroup/Vulkan-ValidationLayers

How to Build and Run

BUILD.md Includes directions for building all components as well as running validation tests.

Information on how to enable the various Validation layers is in LAYER_CONFIGURATION.md.

Version Tagging Scheme

Updates to the VulkanSC-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.

For Vulkan SC, updates to a new API version will be tagged using the following format vksc<version>.<patch> (e.g., vksc1.0.11).
