layers: Validate shared presentable image cases

Add validation support for shared presentable images as defined in
VK_KHR_shared_presentable_image extension.

For all uses of shared presentable images, make sure that the image is
appropriately in VK_IMAGE_LAYOUT_PRESENT_SRC_KHR layout.
For two cases where no layout validation was performed, added a TODO
note (vkCmdBlitImage, vkCmdResolveImage) as basic layout validation
should first be added upstream.
Also locked the layout in the case where a front-buffered image is
presented and then flag an error if an attempt is made to transition
the image layout after that point.

Vulkan Ecosystem Components

This project provides Khronos official ICD loader and validation layers for Vulkan developers on Windows and Linux.

Introduction

Vulkan is an Explicit API, enabling direct control over how GPUs actually work. No (or very little) validation or error checking is done inside a Vulkan driver. Applications have full control and responsibility. Any errors in how Vulkan is used often result in a crash. This project provides standard validation layers that can be enabled to ease development by helping developers verify their applications correctly use the Vulkan API.

Vulkan supports multiple GPUs and multiple global contexts (VkInstance). The ICD loader is necessary to support multiple GPUs and the VkInstance level Vulkan commands. Additionally, the loader manages inserting Vulkan layer libraries, including validation layers between the application and the ICD.

The following components are available in this repository:

Contributing

If you intend to contribute, the preferred work flow is for you to develop your contribution in a fork of this repo in your GitHub account and then submit a pull request. Please see the CONTRIBUTING file in this repository for more details

How to Build and Run

BUILD.md includes directions for building all the components, running the validation tests and running the demo applications.

Information on how to enable the various Validation layers is in layers/README.md.

Architecture and interface information for the loader is in loader/LoaderAndLayerInterface.md.

NOTE: Update Nvidia Drivers

  • A recent glslang change exposed a bug in the texel fetch behavior on Nvidia devices under certain situations.
  • Previously, we reverted the glslang change which exposed it.
  • Nvidia has since resolved the issue, and we are now removing the workaround.
  • Driver installs with the fix are available on their download page, just look for:
  • Linux Drivers starting with version 367.35
  • Windows Drivers starting at version 372.54
