During SDK testing we identified that the runtime copyrights were out-of-date. The loader runtime includes two separate MIT copyrights, each attributed to a pair of source files, one initiated by Dave Gamble and one by joseph werle. I examined these files to discover that the last LunarG change to three out of the four was actually in 2017, not 2016. This date should be attributed to Khronos, Valve, and LunarG. By updating the copyright notice in these files, we ensure that the license registry remains up-to-date. Note that no real content changed (which is why the copyrights are not being updated to 2021).
Vulkan Ecosystem Components
This project provides the Khronos official Vulkan ICD desktop loader for Windows, Linux, and MacOS.
CI 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:

How to Build and Run
BUILD.md Includes directions for building all components.
Architecture and interface information for the loader is in loader/LoaderAndLayerInterface.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.
License
This work is released as open source under a Apache-style license from Khronos including a Khronos copyright.
