VkCommandBufferInheritanceDescriptorHeapInfoEXT

Structure specifying command buffer inheritance information

If the pNext chain of VkCommandBufferInheritanceInfo includes a VkCommandBufferInheritanceDescriptorHeapInfoEXT structure, then that structure indicates that the secondary will use the same descriptor heaps as the primary command buffer.

The VkCommandBufferInheritanceDescriptorHeapInfoEXT structure is defined as:

typedef struct VkCommandBufferInheritanceDescriptorHeapInfoEXT {
    VkStructureType sType;
    const void* pNext;
    const VkBindHeapInfoEXT* pSamplerHeapBindInfo;
    const VkBindHeapInfoEXT* pResourceHeapBindInfo;
} VkCommandBufferInheritanceDescriptorHeapInfoEXT;
  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • pSamplerHeapBindInfo specifies the VkBindHeapInfoEXT of the sampler heap bound using vkCmdBindSamplerHeapEXT in the primary. If this is NULL, it indicates that no sampler heap is bound.
  • pResourceHeapBindInfo specifies the VkBindHeapInfoEXT of the resource heap bound using vkCmdBindResourceHeapEXT in the primary. If this is NULL, it indicates that no resource heap is bound.

If this structure is not present, the behavior is as if pSamplerHeapBindInfo and pResourceHeapBindInfo were both NULL.

Valid Usage

VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-descriptorHeap-11200

If the descriptorHeap feature is not enabled, pSamplerHeapBindInfo must be NULL

VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-descriptorHeap-11201

If the descriptorHeap feature is not enabled, pResourceHeapBindInfo must be NULL

VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pSamplerHeapBindInfo-11470

If pSamplerHeapBindInfo is not NULL, pSamplerHeapBindInfo→heapRange must be a device address range allocated to the application from a buffer created with the VK_BUFFER_USAGE_DESCRIPTOR_HEAP_BIT_EXT usage flag set

VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pResourceHeapBindInfo-11471

If pResourceHeapBindInfo is not NULL, pResourceHeapBindInfo→heapRange must be a device address range allocated to the application from a buffer created with the VK_BUFFER_USAGE_DESCRIPTOR_HEAP_BIT_EXT usage flag set

Valid Usage (Implicit)

VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-sType-sType

sType must be VK_STRUCTURE_TYPE_COMMAND_BUFFER_INHERITANCE_DESCRIPTOR_HEAP_INFO_EXT

VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pSamplerHeapBindInfo-parameter

If pSamplerHeapBindInfo is not NULL, pSamplerHeapBindInfo must be a valid pointer to a valid VkBindHeapInfoEXT structure

VUID-VkCommandBufferInheritanceDescriptorHeapInfoEXT-pResourceHeapBindInfo-parameter

If pResourceHeapBindInfo is not NULL, pResourceHeapBindInfo must be a valid pointer to a valid VkBindHeapInfoEXT structure
