Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

Description

  • minSubgroupSize is the minimum subgroup size supported by this device. minSubgroupSize is at least one if any of the physical device’s queues support VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT. minSubgroupSize is a power-of-two. minSubgroupSize is less than or equal to maxSubgroupSize. minSubgroupSize is less than or equal to subgroupSize.

  • maxSubgroupSize is the maximum subgroup size supported by this device. maxSubgroupSize is at least one if any of the physical device’s queues support VK_QUEUE_GRAPHICS_BIT or VK_QUEUE_COMPUTE_BIT. maxSubgroupSize is a power-of-two. maxSubgroupSize is greater than or equal to minSubgroupSize. maxSubgroupSize is greater than or equal to subgroupSize.

  • maxComputeWorkgroupSubgroups is the maximum number of subgroups supported by the implementation within a workgroup.

  • requiredSubgroupSizeStages is a bitfield of what shader stages support having a required subgroup size specified.

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

  • maxPerStageDescriptorInlineUniformBlock 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.

  • maxInlineUniformTotalSize is the maximum total size in bytes of all inline uniform block bindings, across all pipeline shader stages and descriptor set numbers, that can be included in a pipeline layout. Descriptor bindings with a descriptor type of VK_DESCRIPTOR_TYPE_INLINE_UNIFORM_BLOCK count against this limit.

If the VkPhysicalDeviceVulkan13Properties structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

These properties correspond to Vulkan 1.3 functionality.

The members of VkPhysicalDeviceVulkan13Properties must have the same values as the corresponding members of VkPhysicalDeviceInlineUniformBlockProperties and VkPhysicalDeviceSubgroupSizeControlProperties.
