## Name

VkPhysicalDeviceDescriptorHeapTensorPropertiesARM - Structure describing descriptor heap tensor properties supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceDescriptorHeapTensorPropertiesARM` structure is defined as:

    // Provided by VK_EXT_descriptor_heap with VK_ARM_tensors
    typedef struct VkPhysicalDeviceDescriptorHeapTensorPropertiesARM {
        VkStructureType    sType;
        void*              pNext;
        VkDeviceSize       tensorDescriptorSize;
        VkDeviceSize       tensorDescriptorAlignment;
        size_t             tensorCaptureReplayOpaqueDataSize;
    } VkPhysicalDeviceDescriptorHeapTensorPropertiesARM;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `tensorDescriptorSize` specifies the maximum size of tensor descriptors written by vkWriteResourceDescriptorsEXT.

- `tensorDescriptorAlignment` specifies the required alignment of tensor descriptors within a resource heap. It must be a power-of-two value, and less than or equal to `tensorDescriptorSize`.

- `tensorCaptureReplayOpaqueDataSize` specifies the size of the opaque capture/replay data for an tensor.

## Description

If the `VkPhysicalDeviceDescriptorHeapTensorPropertiesARM` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceDescriptorHeapTensorPropertiesARM-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_DESCRIPTOR_HEAP_TENSOR_PROPERTIES_ARM
