Description
-
VK_DESCRIPTOR_SET_LAYOUT_CREATE_PUSH_DESCRIPTOR_BIT_KHRspecifies 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_BITspecifies that descriptor sets using this layout must be allocated from a descriptor pool created with theVK_DESCRIPTOR_POOL_CREATE_UPDATE_AFTER_BIND_BITbit 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_NVspecifies that descriptor sets using this layout allows them to be bound with compute pipelines that are created withVK_PIPELINE_CREATE_INDIRECT_BINDABLE_BIT_NVflag set to be used in Device-Generated Commands. -
VK_DESCRIPTOR_SET_LAYOUT_CREATE_DESCRIPTOR_BUFFER_BIT_EXTspecifies that this layout must only be used with descriptor buffers. -
VK_DESCRIPTOR_SET_LAYOUT_CREATE_EMBEDDED_IMMUTABLE_SAMPLERS_BIT_EXTspecifies 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_EXTspecifies that descriptor sets using this layout must be allocated from a descriptor pool created with theVK_DESCRIPTOR_POOL_CREATE_HOST_ONLY_BIT_EXTbit 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_NVspecifies that binding numbers in descriptor sets using this layout may represent different resources and/or types of resources in each stage.
