loader: Fix VK_KHR_surface_protected_capabilities Loader is exposing VK_KHR_surface_protected_capabilities instance extension support if one of the ICDs supports it. An ICD, not supporting this extension, will not know about VkSurfaceProtectedCapabilitiesKHR being passed as additional structure to VkPhysicalDeviceSurfaceInfo2KHR in vulkan API vkGetPhysicalDeviceSurfaceCapabilities2KHR(). Reset VkSurfaceProtectedCapabilitiesKHR.supportsProtected to false always before calling vkGetPhysicalDeviceSurfaceCapabilities2KHR(). If a particular ICD supports protected surfaces then it will set it true. An application will always receive either 1/0 in supportsProtected as expected. The issue got exposed through below CTS test failure on a Optimus windows system with different ICDs versions, one supporting this extension and another not supporting it. - dEQP-VK.wsi.win32.surface.query_protected_capabilities
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 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.
