VkMemoryAllocateFlagBits

Bits which can be set in VkMemoryAllocateFlagsInfo::flags, controlling device memory allocation, are:

typedef enum VkMemoryAllocateFlagBits {
    VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT = 0x00000001,
} VkMemoryAllocateFlagBits;

or the equivalent

#define VkMemoryAllocateFlagBitsKHR VkMemoryAllocateFlagBits

• VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT specifies that memory will be allocated for the devices in VkMemoryAllocateFlagsInfo::deviceMask.
• VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT specifies that the memory can be attached to a buffer object created with the VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT bit set in usage, and that the memory handle can be used to retrieve an opaque address via vkGetDeviceMemoryOpaqueCaptureAddress.
• VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT specifies that the memory’s address can be saved and reused on a subsequent run (e.g. for trace capture and replay), see VkBufferOpaqueCaptureAddressCreateInfo for more detail.
