[build][c++23] Allow deprecations in Vulkan validation layers

There's a use of a std::aligned_union which is deprecated in C++23, but
this is gone in newer upstream versions of the code. But the upstream
code has changed significantly, so patching our version would make
updating harder, and updating to the latest upstream code may be
non-trivial.

Vulkan Validation Layers (VVL)

Introduction

Vulkan is an Explicit API, enabling direct control over how GPUs actually work. By design, minimal error checking is done inside a Vulkan driver. Applications have full control and responsibility for correct operation. Any errors in how Vulkan is used can result in a crash. This project provides Vulkan validation layers that can be enabled to assist development by enabling developers to verify their applications correct use of the Vulkan API.

Getting Binaries

For those who don't want to build from source, there are few ways to get working binaries to use

  • The Vulkan SDK will have the most well tested versions of the layer
  • For Android, each SDK tag will have binaries to download (example: vulkan-sdk-1.3.280.0 tag)
  • Every change applied to the main branch runs through GitHub action and will produce artifacts of the latest commit.

Adjusting settings

See settings documentation.

Community Assistance

Before submitting an issue to the validation layers or reaching out to the developers it may be prudent to reach out to the community first. These resources can be helpful to refine your issue, work out an application/driver bug, etc.

Contact Information

  • @KhronosGroup/VVL-CODEOWNERS
  • VVL-CODEOWNERS can also be found on aforementioned Slack channel for direct contact.

Internals

The Validation Layers are broken up as many smaller internal “Validation Objects” each tasked with their own job. Core Checks is what is enabled by default, but there are other validation objects that can be additionally enabled, such as Synchronization Validation, GPU Assisted Validation, and more. There are also a few limitations stemming from the Validation layers being a Vulkan layer.

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.

Weekly automated (and untested) tags are generated with the following format: snapshot-<year>wk<week-number>, eg. snapshot-2024wk06.
