Remove duplicate driver workaround for macOS

On macOS, applications can bundle drivers with themselves. When they do
this and also install the same driver to a global location, the loader
will load 2 separate drivers which happen to be the same binary,
causing the linker to emit warnings.

The fix was to simply only load one driver if the app was bundled.
Because there was only one macOS driver available, this worked. Now that
both KosmicKrisp and LavaPipe are available, this workaround is no
longer appropriate. If apps bundle multiple drivers, they would be
unable to use more than 1.

Vulkan Loader

This project provides the Khronos official Vulkan Loader for all platforms except Android

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 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.
