# VkPhysicalDeviceInlineUniformBlockProperties(3) Manual Page

## Name

VkPhysicalDeviceInlineUniformBlockProperties - Structure describing inline uniform block properties that can be supported by an implementation

Loading… please wait.

## C Specification

The `VkPhysicalDeviceInlineUniformBlockProperties` structure is defined as:

    // Provided by VK_VERSION_1_3
    typedef struct VkPhysicalDeviceInlineUniformBlockProperties {
        VkStructureType    sType;
        void*              pNext;
        uint32_t           maxInlineUniformBlockSize;
        uint32_t           maxPerStageDescriptorInlineUniformBlocks;
        uint32_t           maxPerStageDescriptorUpdateAfterBindInlineUniformBlocks;
        uint32_t           maxDescriptorSetInlineUniformBlocks;
        uint32_t           maxDescriptorSetUpdateAfterBindInlineUniformBlocks;
    } VkPhysicalDeviceInlineUniformBlockProperties;

    // Provided by VK_EXT_inline_uniform_block
    // Equivalent to VkPhysicalDeviceInlineUniformBlockProperties
    typedef VkPhysicalDeviceInlineUniformBlockProperties VkPhysicalDeviceInlineUniformBlockPropertiesEXT;

## Members

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

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

## Description

- `maxInlineUniformBlockSize` is the maximum size in bytes of an inline uniform block binding.

- `maxPerStageDescriptorInlineUniformBlocks` is the maximum number of inline uniform block bindings that can be accessible to a single shader stage in a pipeline layout. Descriptor bindings with a descriptor type of VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK count against this limit. Only descriptor bindings in descriptor set layouts created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit.

- `maxPerStageDescriptorUpdateAfterBindInlineUniformBlocks` is similar to `maxPerStageDescriptorInlineUniformBlocks` but counts descriptor bindings from descriptor sets created with or without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set.

- `maxDescriptorSetInlineUniformBlocks` is the maximum number of inline uniform block bindings that can be included in descriptor bindings in a pipeline layout across all pipeline shader stages and descriptor set numbers. Descriptor bindings with a descriptor type of VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK count against this limit. Only descriptor bindings in descriptor set layouts created without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit.

- `maxDescriptorSetUpdateAfterBindInlineUniformBlocks` is similar to `maxDescriptorSetInlineUniformBlocks` but counts descriptor bindings from descriptor sets created with or without the VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set.

If the `VkPhysicalDeviceInlineUniformBlockProperties` 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-VkPhysicalDeviceInlineUniformBlockProperties-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_INLINE_UNIFORM_BLOCK_PROPERTIES
