VkPhysicalDeviceDescriptorBufferFeaturesEXT

The VkPhysicalDeviceDescriptorBufferFeaturesEXT structure is defined as:

typedef struct VkPhysicalDeviceDescriptorBufferFeaturesEXT {
    VkStructureType sType;
    void* pNext;
    VkBool32 descriptorBuffer;
    VkBool32 descriptorBufferCaptureReplay;
    VkBool32 descriptorBufferImageLayoutIgnored;
    VkBool32 descriptorBufferPushDescriptors;
} VkPhysicalDeviceDescriptorBufferFeaturesEXT;

This structure describes the following feature:

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• descriptorBuffer indicates that the implementation supports putting shader-accessible descriptors directly in memory.
• descriptorBufferCaptureReplay indicates 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_SAMPLER_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXT, or VK_ACCELERATION_STRUCTURE_CREATE_DESCRIPTOR_BUFFER_CAPTURE_REPLAY_BIT_EXTmust be created before resources of the same types without those flags.
• descriptorBufferImageLayoutIgnored indicates that the implementation will ignore imageLayout in VkDescriptorImageInfo when calling vkGetDescriptorEXT.
• descriptorBufferPushDescriptors indicates that the implementation supports using push descriptors with descriptor buffers.

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. VkPhysicalDeviceDescriptorBufferFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.
