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 PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR

New Enum Constants

• KHR_ZERO_INITIALIZE_WORKGROUP_MEMORY_EXTENSION_NAME

• KHR_ZERO_INITIALIZE_WORKGROUP_MEMORY_SPEC_VERSION

• Extending StructureType:

  • 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.

Version History

• Revision 1, 2020-11-18 (Alan Baker)
