C Specification
The VkPhysicalDeviceDescriptorBufferFeaturesEXT structure is defined
as:
// Provided by VK_EXT_descriptor_buffer
typedef struct VkPhysicalDeviceDescriptorBufferFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 descriptorBuffer;
VkBool32 descriptorBufferCaptureReplay;
VkBool32 descriptorBufferImageLayoutIgnored;
VkBool32 descriptorBufferPushDescriptors;
} VkPhysicalDeviceDescriptorBufferFeaturesEXT;Members
This structure describes the following feature:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
descriptorBufferindicates that the implementation supports putting shader-accessible descriptors directly in memory. -
descriptorBufferCaptureReplayindicates that the implementation supports capture and replay when using descriptor buffers. If this is VK_TRUE, all resources created with VK_BUFFER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT, VK_IMAGE_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT, VK_IMAGE_VIEW_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT, VK_TENSOR_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_ARM, VK_TENSOR_VIEW_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_ARM, VK_SAMPLER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT, or VK_ACCELERATION_STRUCTURE_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT must be created before resources of the same types without those flags. -
descriptorBufferImageLayoutIgnoredindicates that the implementation will ignoreimageLayoutinVkDescriptorImageInfowhen calling vkGetDescriptorEXT. -
descriptorBufferPushDescriptorsindicates that the implementation supports using push descriptors with descriptor buffers.
Description
If the VkPhysicalDeviceDescriptorBufferFeaturesEXT structure is included in the pNext chain of the
VkPhysicalDeviceFeatures2 structure passed to
vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each
corresponding feature is supported.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceDescriptorBufferFeaturesEXT, it must add an instance of the structure,
with the desired feature members set to VK_TRUE, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
