C Specification
Bits which can be set in VkMemoryAllocateFlagsInfo::flags
,
controlling device memory allocation, are:
typedef enum VkMemoryAllocateFlagBits {
VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT = 0x00000001,
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT_KHR = 0x00000002,
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT_KHR = 0x00000004,
VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT_KHR = VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT,
VK_MEMORY_ALLOCATE_FLAG_BITS_MAX_ENUM = 0x7FFFFFFF
} VkMemoryAllocateFlagBits;
or the equivalent
typedef VkMemoryAllocateFlagBits VkMemoryAllocateFlagBitsKHR;
Description
-
VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT
specifies that memory will be allocated for the devices in VkMemoryAllocateFlagsInfo::deviceMask
. -
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT_KHR
specifies that the memory can be attached to a buffer object created with theVK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT_KHR
bit set inusage
, and that the memory handle can be used to retrieve an opaque address via vkGetDeviceMemoryOpaqueCaptureAddressKHR. -
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT_KHR
specifies that the memory’s address can be saved and reused on a subsequent run (e.g. for trace capture and replay), see VkBufferOpaqueCaptureAddressCreateInfoKHR for more detail.
