VkDescriptorSetLayoutCreateFlagBits

Bitmask specifying descriptor set layout properties

Bits which can be set in VkDescriptorSetLayoutCreateInfo::flags, specifying options for descriptor set layout, are:

typedef enum VkDescriptorSetLayoutCreateFlagBits {

} VkDescriptorSetLayoutCreateFlagBits;
  • VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHR specifies that descriptor sets must not be allocated using this layout, and descriptors are instead pushed by vkCmdPushDescriptorSetKHR.
  • VK_DESCRIPTOR_SET_LAYOUT_CREATE_UPDATE_AFTER_BIND_POOL_BIT specifies that descriptor sets using this layout must be allocated from a descriptor pool created with the VK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BIT bit set. Descriptor set layouts created with this bit set have alternate limits for the maximum number of descriptors per-stage and per-pipeline layout. The non-UpdateAfterBind limits only count descriptors in sets created without this flag. The UpdateAfterBind limits count all descriptors, but the limits may be higher than the non-UpdateAfterBind limits.
  • VK_DESCRIPTOR_SET_LAYOUT_CREATE_INDIRECT_BINDABLE_BIT_NV specifies that descriptor sets using this layout allows them to be bound with compute pipelines that are created with VK_PIPELINE_CREATE_INDIRECT_BINDABLE_BIT_NV flag set to be used in Device-Generated Commands.
  • VK_DESCRIPTOR_SET_LAYOUT_CREATE_DESCRIPTOR_BUFFER_BIT_EXT specifies that this layout must only be used with descriptor buffers.
  • VK_DESCRIPTOR_SET_LAYOUT_CREATE_EMBEDDED_IMMUTABLE_SAMPLERS_BIT_EXT specifies that this is a layout only containing immutable samplers that can be bound by vkCmdBindDescriptorBufferEmbeddedSamplersEXT. Unlike normal immutable samplers, embedded immutable samplers do not require the application to provide them in a descriptor buffer.
  • VK_DESCRIPTOR_SET_LAYOUT_CREATE_HOST_ONLY_POOL_BIT_EXT specifies that descriptor sets using this layout must be allocated from a descriptor pool created with the VK_DESCRIPTOR_POOL_CREATE_HOST_ONLY_BIT_EXT bit set. Descriptor set layouts created with this bit have no expressible limit for maximum number of descriptors per-stage. Host descriptor sets are limited only by available host memory, but may be limited for implementation specific reasons. Implementations may limit the number of supported descriptors to UpdateAfterBind limits or non-UpdateAfterBind limits, whichever is larger.
  • VK_DESCRIPTOR_SET_LAYOUT_CREATE_PER_STAGE_BIT_NV specifies that binding numbers in descriptor sets using this layout may represent different resources and/or types of resources in each stage.
