VKMEMORYPROPERTYDEVICELOCALBIT

VKMEMORYPROPER is a structure in the Vulkan API, which is a low-level graphics and compute API. It is used to describe the properties of a memory object, such as its type, heap index, and usage flags. The structure is defined as follows:

typedef struct VkMemoryPropertyFlags {

VkFlags flags;

} VkMemoryPropertyFlags;

The flags field is a bitmask of VkMemoryPropertyFlagBits values, which describe the properties of the memory object. The possible values are:

VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT: The memory is located on the device and is not accessible by the host.

VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT: The memory is visible to the host and can be accessed using host pointers.

VK_MEMORY_PROPERTY_HOST_COHERENT_BIT: The memory is coherent between the host and the device.

VK_MEMORY_PROPERTY_HOST_CACHED_BIT: The memory is cached on the host.

VK_MEMORY_PROPERTY_LAZILY_ALLOCATED_BIT: The memory is lazily allocated and may not be physically allocated until it is used.

The VKMEMORYPROPER structure is used in conjunction with other Vulkan structures, such as VkMemoryRequirements and VkMemoryAllocateInfo, to allocate and manage memory objects in Vulkan. It is an important part of the Vulkan API, as it allows developers to control the properties of memory objects and optimize their performance.
