Description

This extension adds support for performing copies between memory and image regions using indirect parameters that are read by the device from a buffer during execution. This functionality may be useful for performing copies where the copy parameters are not known during the command buffer creation time.

New Commands

• vkCmdCopyMemoryIndirectKHR
• vkCmdCopyMemoryToImageIndirectKHR

New Structures

• VkCopyMemoryIndirectCommandKHR
• VkCopyMemoryIndirectInfoKHR
• VkCopyMemoryToImageIndirectCommandKHR
• VkCopyMemoryToImageIndirectInfoKHR
• VkStridedDeviceAddressRangeKHR
• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
  • VkPhysicalDeviceCopyMemoryIndirectFeaturesKHR
• Extending VkPhysicalDeviceProperties2:
  • VkPhysicalDeviceCopyMemoryIndirectPropertiesKHR

New Enums

• VkAddressCopyFlagBitsKHR

New Bitmasks

• VkAddressCopyFlagsKHR

New Enum Constants

• VK_KHR_COPY_MEMORY_INDIRECT_EXTENSION_NAME
• VK_KHR_COPY_MEMORY_INDIRECT_SPEC_VERSION
• Extending VkFormatFeatureFlagBits2:
  • VK_FORMAT_FEATURE_2_COPY_IMAGE_INDIRECT_DST_BIT_KHR
• Extending VkPipelineStageFlagBits2:
  • VK_PIPELINE_STAGE_2_COPY_INDIRECT_BIT_KHR
• Extending VkStructureType:
  • VK_STRUCTURE_TYPE_COPY_MEMORY_INDIRECT_INFO_KHR
  • VK_STRUCTURE_TYPE_COPY_MEMORY_TO_IMAGE_INDIRECT_INFO_KHR
  • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COPY_MEMORY_INDIRECT_FEATURES_KHR
  • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_COPY_MEMORY_INDIRECT_PROPERTIES_KHR
