Description

This extension allows protected memory access to be specified per pipeline as opposed to per device. Through the usage of this extension, any performance penalty paid due to access to protected memory will be limited to the specific pipelines that make such accesses.

New Structures

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDevicePipelineProtectedAccessFeaturesEXT

New Enum Constants

• EXT_PIPELINE_PROTECTED_ACCESS_EXTENSION_NAME

• EXT_PIPELINE_PROTECTED_ACCESS_SPEC_VERSION

• Extending PipelineCreateFlagBits:

  • PIPELINE_CREATE_NO_PROTECTED_ACCESS_BIT_EXT
  • PIPELINE_CREATE_PROTECTED_ACCESS_ONLY_BIT_EXT

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_PIPELINE_PROTECTED_ACCESS_FEATURES_EXT

Version History

• Revision 1, 2022-07-28 (Shahbaz Youssefi)

VkPhysicalDevicePipelineProtectedAccessFeaturesEXT - Structure describing support for specifying protected access on individual pipelines

Members

This structure describes the following feature:

Description

If the PhysicalDevicePipelineProtectedAccessFeaturesEXT 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. PhysicalDevicePipelineProtectedAccessFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)
