Description
This extension allows the use of a null constant initializer on shader Workgroup memory variables, allowing implementations to expose any special hardware or instructions they may have. Zero initialization is commonly used by applications running untrusted content (e.g. web browsers) as way of defeating memory-scraping attacks.
New Structures
- Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
New Enum Constants
VK_KHR_ZERO_INITIALIZE_WORKGROUP_MEMORY_EXTENSION_NAME
VK_KHR_ZERO_INITIALIZE_WORKGROUP_MEMORY_SPEC_VERSION
- Extending VkStructureType:
VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ZERO_INITIALIZE_WORKGROUP_MEMORY_FEATURES_KHR
Promotion to Vulkan 1.3
Functionality in this extension is included in core Vulkan 1.3, with the KHR suffix omitted. The original type, enum, and command names are still available as aliases of the core functionality.
