Mark Young 383cf8a6d3 Test layer pre-instance functions 
Add tests to verify that the 3 pre-instance functions are properly
intercepted by the layer when everything is well-defined.

Also include two fixes:
 1) Disable environment variable value of 0 should be treated the same as not present
 2) The vkEnumerateInstanceVersion override path was broken, missing a NULL check

Vulkan Ecosystem Components

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

CI Build Status

Build Status

Introduction

Vulkan is an explicit API, enabling direct control over how GPUs actually work. As such, Vulkan supports systems that have multiple GPUs, each running with a different driver, or ICD (Installable Client Driver). Vulkan also supports multiple global contexts (instances, in Vulkan terminology). The ICD loader is a library that is placed between a Vulkan application and any number of Vulkan drivers, in order to support multiple drivers and the instance-level functionality that works across these drivers. Additionally, the loader manages inserting Vulkan layer libraries, such as validation layers, between an application and the drivers.

This repository contains the Vulkan loader that is used for Linux, Windows, MacOS, and iOS. There is also a separate loader, maintained by Google, which is used on Android.

The following components are available in this repository:

Information for Developing or Contributing

Please see the CONTRIBUTING.md file in this repository for more details. Please see the GOVERNANCE.md file in this repository for repository management details.

How to Build and Run

BUILD.md Includes directions for building all components.

Architecture and interface information for the loader is in docs/LoaderInterfaceArchitecture.md.

Version Tagging Scheme

Updates to the Vulkan-Loader 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.
