loader: Do not remove duplicated layers Linux can support multiple ABIs, but Vulkan Layer manifest does not allow to specify different library paths, based on the ABI. As a solution, for ICDs, we can simply create multiple manifests, one per ABI, and the Loader will try them one by one until it finds the library that is compatible with the executable class. Instead, for Vulkan Layers, this method doesn't work because the Loader will discard the manifests that have a duplicated layer name. To add support for multiple ABIs to Vulkan Layers, and to make the behavior similar to the ICDs, with this commit we remove the duplicated layer name check. Instead we add to the output list all the Vulkan Layers that we find, and only when we are actually going to dlopen them, we discard the layers with the same name that we already successfully opened.

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:
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.
BUILD.md Includes directions for building all components.
Architecture and interface information for the loader is in loader/LoaderAndLayerInterface.md.
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.
This work is released as open source under a Apache-style license from Khronos including a Khronos copyright.
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; Khronos providing oversight and hosting of the project.
