Description

Vulkan Version 1.1 promoted a number of key extensions into the core API:

  • VK_KHR_16bit_storage

  • VK_KHR_bind_memory2

  • VK_KHR_dedicated_allocation

  • VK_KHR_descriptor_update_template

  • VK_KHR_device_group

  • VK_KHR_device_group_creation

  • VK_KHR_external_fence

  • VK_KHR_external_fence_capabilities

  • VK_KHR_external_memory

  • VK_KHR_external_memory_capabilities

  • VK_KHR_external_semaphore

  • VK_KHR_external_semaphore_capabilities

  • VK_KHR_get_memory_requirements2

  • VK_KHR_get_physical_device_properties2

  • VK_KHR_maintenance1

  • VK_KHR_maintenance2

  • VK_KHR_maintenance3

  • VK_KHR_multiview

  • VK_KHR_relaxed_block_layout

  • VK_KHR_sampler_ycbcr_conversion

  • VK_KHR_shader_draw_parameters

  • VK_KHR_storage_buffer_storage_class

  • VK_KHR_variable_pointers

All differences in behavior between these extensions and the corresponding Vulkan 1.1 functionality are summarized below.

Differences Relative to VK_KHR_16bit_storage

If the VK_KHR_16bit_storage extension is not supported, support for the storageBuffer16BitAccess feature is optional. Support for this feature is defined by VkPhysicalDevice16BitStorageFeatures::storageBuffer16BitAccess or VkPhysicalDeviceVulkan11Features::storageBuffer16BitAccess when queried via vkGetPhysicalDeviceFeatures2.

Differences Relative to VK_KHR_sampler_ycbcr_conversion

If the VK_KHR_sampler_ycbcr_conversion extension is not supported, support for the samplerYcbcrConversion feature is optional. Support for this feature is defined by VkPhysicalDeviceSamplerYcbcrConversionFeatures::samplerYcbcrConversion or VkPhysicalDeviceVulkan11Features::samplerYcbcrConversion when queried via vkGetPhysicalDeviceFeatures2.

Differences Relative to VK_KHR_shader_draw_parameters

If the VK_KHR_shader_draw_parameters extension is not supported, support for the SPV_KHR_shader_draw_parameters SPIR-V extension is optional. Support for this feature is defined by VkPhysicalDeviceShaderDrawParametersFeatures::shaderDrawParameters or VkPhysicalDeviceVulkan11Features::shaderDrawParameters when queried via vkGetPhysicalDeviceFeatures2.

Differences Relative to VK_KHR_variable_pointers

If the VK_KHR_variable_pointers extension is not supported, support for the variablePointersStorageBuffer feature is optional. Support for this feature is defined by VkPhysicalDeviceVariablePointersFeatures::variablePointersStorageBuffer or VkPhysicalDeviceVulkan11Features::variablePointersStorageBuffer when queried via vkGetPhysicalDeviceFeatures2.

Additional Vulkan 1.1 Feature Support

In addition to the promoted extensions described above, Vulkan 1.1 added support for:

New Macros

New Object Types

New Commands

New Structures

New Enums

New Bitmasks

New Enum Constants
