VkMemoryAllocateFlagBits(3)
C Specification
Bits which can be set in VkMemoryAllocateFlagsInfo::flags,
controlling device memory allocation, are:
// Provided by VK_VERSION_1_1
typedef enum VkMemoryAllocateFlagBits {
VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT = 0x00000001,
// Provided by VK_VERSION_1_2
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT = 0x00000002,
// Provided by VK_VERSION_1_2
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT = 0x00000004,
// Provided by VK_EXT_zero_initialize_device_memory
VK_MEMORY_ALLOCATE_ZERO_INITIALIZE_BIT_EXT = 0x00000008,
// Provided by VK_KHR_device_group
VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT_KHR = VK_MEMORY_ALLOCATE_DEVICE_MASK_BIT,
// Provided by VK_KHR_buffer_device_address
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT_KHR = VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT,
// Provided by VK_KHR_buffer_device_address
VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT_KHR = VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_CAPTURE_REPLAY_BIT,
} VkMemoryAllocateFlagBits;// Provided by VK_KHR_device_group
// Equivalent to VkMemoryAllocateFlagBits
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 specifies that the memory can be attached to a buffer object created with the VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT usage flag set.
-
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. If this bit is set, VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT must also be set.
-
VK_MEMORY_ALLOCATE_ZERO_INITIALIZE_BIT_EXT specifies that the memory will be zeroed automatically by the implementation before application is able to access it.
