C Specification

The VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE structure is defined as:

// Provided by VK_VALVE_buffer_device_address_allocation_alignment
typedef struct VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE {
    VkStructureType    sType;
    void*              pNext;
    uint32_t           maxBufferDeviceAddressAllocationAlignment;
} VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE;

Members

This structure describes the following features:

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • maxBufferDeviceAddressAllocationAlignment indicates the maximum alignment which can be requested when allocating buffer device addresses.

Description

If the implementation already requires device memory allocation alignments greater-or-equal to the minimum limit of 64 KiB, implementations should not advertise a larger limit than what the implementation already uses internally, effectively making this extension a no-op, while letting the application have some guarantees for returned device addresses.

If the VkPhysicalDeviceBufferDeviceAddressAllocationAlignmentPropertiesVALVE structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
