Description

Applications may wish to update a fixed set of descriptors in a large number of descriptors sets very frequently, i.e. during initializaton phase or if it is required to rebuild descriptor sets for each frame. For those cases it is also not unlikely that all information required to update a single descriptor set is stored in a single struct. This extension provides a way to update a fixed set of descriptors in a single DescriptorSet with a pointer to a user defined data structure describing the new descriptors.

Promotion to Vulkan 1.1

cmdPushDescriptorSetWithTemplateKHR is included as an interaction with VK_KHR_push_descriptor. If Vulkan 1.1 and VK_KHR_push_descriptor are supported, this is included by VK_KHR_push_descriptor.

The base functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.

type KHR_DESCRIPTOR_UPDATE_TEMPLATE_EXTENSION_NAME = "VK_KHR_descriptor_update_template" Source #

Arguments

:: forall io. MonadIO io 
=> CommandBuffer

commandBuffer is the command buffer that the descriptors will be recorded in.

-> DescriptorUpdateTemplate

descriptorUpdateTemplate is a descriptor update template defining how to interpret the descriptor information in pData.

-> PipelineLayout

layout is a PipelineLayout object used to program the bindings. It must be compatible with the layout used to create the descriptorUpdateTemplate handle.

-> ("set" ::: Word32)

set is the set number of the descriptor set in the pipeline layout that will be updated. This must be the same number used to create the descriptorUpdateTemplate handle.

-> ("data" ::: Ptr ())

pData is a pointer to memory containing descriptors for the templated update.

-> io () 

vkCmdPushDescriptorSetWithTemplateKHR - Pushes descriptor updates into a command buffer using a descriptor update template

Valid Usage

  • The pipelineBindPoint specified during the creation of the descriptor update template must be supported by the commandBuffer’s parent CommandPool’s queue family

Valid Usage (Implicit)

  • descriptorUpdateTemplate must be a valid DescriptorUpdateTemplate handle
  • layout must be a valid PipelineLayout handle
  • commandBuffer must be in the recording state
  • The CommandPool that commandBuffer was allocated from must support graphics, or compute operations
  • Each of commandBuffer, descriptorUpdateTemplate, and layout must have been created, allocated, or retrieved from the same Device

Host Synchronization

  • Host access to commandBuffer must be externally synchronized
  • Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

DebugReportObjectTypeEXT and Vulkan Handle Relationship

Note

The primary expected use of ERROR_VALIDATION_FAILED_EXT is for validation layer testing. It is not expected that an application would see this error code during normal use of the validation layers.
