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.

VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR - Structure describing support for zero initialization of workgroup memory by an implementation

Members

This structure describes the following feature:

Description

If the PhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
