loader: const fixes

Make the 'source_override' parameter of loader_get_manifest_files() const.
The const was removed in 74d013a5, seemingly for convenience of calling
loader_free_getenv(), not because it was incorrect.

Give loader_free_getenv() the same signature in all implementations.

Fix a memory leak where it was possible to exit loader_get_manifest_files()
without calling loader_free_getenv().

Don't pass a potentially NULL value to loader_log().

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 respository 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
