C Specification

The VkPhysicalDeviceNestedCommandBufferFeaturesEXT structure is defined as:

// Provided by VK_EXT_nested_command_buffer
typedef struct VkPhysicalDeviceNestedCommandBufferFeaturesEXT {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           nestedCommandBuffer;
    VkBool32           nestedCommandBufferRendering;
    VkBool32           nestedCommandBufferSimultaneousUse;
} VkPhysicalDeviceNestedCommandBufferFeaturesEXT;

Members

This structure describes the following features:

  • nestedCommandBuffer indicates the implementation supports nested command buffers, which allows Secondary Command Buffers to execute other Secondary Command Buffers.

  • nestedCommandBufferRendering indicates that it is valid to call vkCmdExecuteCommands inside a Secondary Command Buffer recorded with VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT.

  • nestedCommandBufferSimultaneousUse indicates that the implementation supports nested command buffers with command buffers that are recorded with VK_COMMAND_BUFFER_USAGE_SIMULTANEOUS_USE_BIT.

Description

If the VkPhysicalDeviceNestedCommandBufferFeaturesEXT structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. VkPhysicalDeviceNestedCommandBufferFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceNestedCommandBufferFeaturesEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_NESTED_COMMAND_BUFFER_FEATURES_EXT
