INF-0007 - DXC Vulkan SDK Release Strategy

Status	Under Consideration
Author	Damyan Pepper
Sponsor	Damyan Pepper

Impacted Projects: DXC

Introduction

DXC is included in the Vulkan SDK. Before each SDK release, the DXC submodule references (SPIRV-Headers, SPIRV-Tools) need to be updated and the product needs to be tested. This process has previously been mostly performed manually. This document details the requirements for ensuring DXC is ready for inclusion in the Vulkan SDK and proposes the changes required in order to satisfy them.

Motivation

SPIRV-Headers and SPIRV-Tools need to be kept up to date so that the most recent SPIRV features are available in DXC. We need to verify that DXC is generating valid SPIRV code and that there are no regressions. The process needs to be documented and automated enough so that it does not rely on individuals with special knowledge. Additionally, we want to align the version included in the Vulkan SDK with a formal DXC release so that it matches up with GitHub and NuGet releases and can be ingested into Godbolt.
