Handle invalid files & symlinks properly If loader_get_json fails due to the file missing or the file being a stale symlink, it returns VK_ERROR_INITIALIZATION_FAILED which loader_parse_icd_manifest passed upwards. Since the caller of loader_parse_icd_manifest wasn't expecting that error code, it didn't skip the ICD, causing an infinite recusion in EnumInstExtProps due to the call to dlsym("vkEnumerateInstanceExtensionProperties"); This also required changes to callers of loader_get_json which would propagate VK_ERROR_INITIALIZATION failed during layer searching to no longer cause vkCreateInstance to abort if any invalid files were found. Added tests for symlinks as the origin of this bug is due to 'stale' symlinks after driver installers
This project provides the Khronos official Vulkan ICD desktop loader for Windows, Linux, and MacOS.
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 docs/LoaderInterfaceArchitecture.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.
