Fields

• maintenance7 :: Bool

  maintenance7 indicates that the implementation supports the following:

  • The RENDERING_CONTENTS_INLINE_BIT_KHR and SUBPASS_CONTENTS_INLINE_AND_SECONDARY_COMMAND_BUFFERS_KHR flags can be used to record commands in render pass instances both inline and in secondary command buffers executed with cmdExecuteCommands for dynamic rendering and legacy render passes respectively.
  • Querying information regarding the underlying devices in environments where the Vulkan implementation is provided through layered implementations. This is done by chaining PhysicalDeviceLayeredApiPropertiesListKHR to PhysicalDeviceProperties2.
  • New limits which indicate the maximum total count of dynamic uniform buffers and dynamic storage buffers that can be included in a pipeline layout.
  • 32-bit timestamp queries must wrap on overflow
  • A property that indicates whether a fragment shading rate attachment can have a size that is too small to cover a specified render area.
  • A property that indicates support for writing to one aspect of a depth/stencil attachment without performing a read-modify-write operation on the other aspect

Fields

• robustFragmentShadingRateAttachmentAccess :: Bool

  robustFragmentShadingRateAttachmentAccess indicates whether the scaled size of a fragment shading rate attachment can be less than the size of the render area. If robustFragmentShadingRateAttachmentAccess is FALSE, the size of the attachment multiplied by the texel size must be greater than or equal to the size of the render area. If it is TRUE and the fragment shading rate attachment was created with ImageSubresourceRange::baseMipLevel equal to 0, the scaled size can be smaller than the render area, with missing shading rates defined by out of bounds behavior.

• separateDepthStencilAttachmentAccess :: Bool

  separateDepthStencilAttachmentAccess indicates support for writing to one aspect of a depth/stencil attachment without performing read-modify-write operations on the other aspect. If this property is TRUE, writes to one aspect must not result in read-modify-write operations on the other aspect. If FALSE, writes to one aspect may result in writes to the other aspect as defined by render pass load operations, render pass store operations and render pass resolve operations.

• maxDescriptorSetTotalUniformBuffersDynamic :: Word32

  maxDescriptorSetTotalUniformBuffersDynamic is the maximum total count of dynamic uniform buffers that can be included in a pipeline layout. Descriptors with a type of DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC count against this limit. Only descriptors in descriptor set layouts created without the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit. See https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#descriptorsets-uniformbufferdynamic.

• maxDescriptorSetTotalStorageBuffersDynamic :: Word32

  maxDescriptorSetTotalStorageBuffersDynamic is the maximum total count of dynamic storage buffers that can be included in a pipeline layout. Descriptors with a type of DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC count against this limit. Only descriptors in descriptor set layouts created without the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit. See https://registry.khronos.org/vulkan/specs/latest/html/vkspec.html#descriptorsets-storagebufferdynamic.

• maxDescriptorSetTotalBuffersDynamic :: Word32

  maxDescriptorSetTotalBuffersDynamic is the maximum total count of dynamic uniform buffers and storage buffers that can be included in a pipeline layout. Descriptors with a type of DESCRIPTOR_TYPE_UNIFORM_BUFFER_DYNAMIC or DESCRIPTOR_TYPE_STORAGE_BUFFER_DYNAMIC count against this limit. Only descriptors in descriptor set layouts created without the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set count against this limit.

• maxDescriptorSetUpdateAfterBindTotalUniformBuffersDynamic :: Word32

  maxDescriptorSetUpdateAfterBindTotalUniformBuffersDynamic is similar to maxDescriptorSetTotalUniformBuffersDynamic but counts descriptors from descriptor sets created with or without the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set.

• maxDescriptorSetUpdateAfterBindTotalStorageBuffersDynamic :: Word32

  maxDescriptorSetUpdateAfterBindTotalStorageBuffersDynamic is similar to maxDescriptorSetTotalStorageBuffersDynamic but counts descriptors from descriptor sets created with or without the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set.

• maxDescriptorSetUpdateAfterBindTotalBuffersDynamic :: Word32

  maxDescriptorSetUpdateAfterBindTotalBuffersDynamic is similar to maxDescriptorSetTotalBuffersDynamic but counts descriptors from descriptor sets created with or without the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT bit set. While an application can allocate dynamic storage buffer descriptors from a pool created with the DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT, bindings for these descriptors must not be present in any descriptor set layout that includes bindings created with DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT.

Fields

• layeredApiCount :: Word32

  layeredApiCount is an integer related to the number of layered implementations underneath the Vulkan physical device, as described below.

• layeredApis :: Ptr (PhysicalDeviceLayeredApiPropertiesKHR ('[] :: [Type]))

  pLayeredApis is a pointer to an array of PhysicalDeviceLayeredApiPropertiesKHR in which information regarding the layered implementations underneath the Vulkan physical device are returned.

Fields

• next :: Chain es

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

• vendorID :: Word32

  vendorID is a unique identifier for the vendor of the layered implementation.

• deviceID :: Word32

  deviceID is a unique identifier for the layered implementation among devices available from the vendor.

• layeredAPI :: PhysicalDeviceLayeredApiKHR

  layeredAPI is a PhysicalDeviceLayeredApiKHR specifying the API implemented by the layered implementation.

• deviceName :: ByteString

  deviceName is an array of MAX_PHYSICAL_DEVICE_NAME_SIZE char containing a null-terminated UTF-8 string which is the name of the device.

Fields

• properties :: SomeStruct PhysicalDeviceProperties2

  properties is a PhysicalDeviceProperties2 in which properties of the underlying layered Vulkan implementation are returned.
