Pointer information

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CU_POINTER_ATTRIBUTE_CONTEXT = 1

< The ::CUcontext on which a pointer was allocated or registered

CU_POINTER_ATTRIBUTE_MEMORY_TYPE = 2

< The ::CUmemorytype describing the physical location of a pointer

CU_POINTER_ATTRIBUTE_DEVICE_POINTER = 3

< The address at which a pointer’s memory may be accessed on the device

CU_POINTER_ATTRIBUTE_HOST_POINTER = 4

< The address at which a pointer’s memory may be accessed on the host

CU_POINTER_ATTRIBUTE_P2P_TOKENS = 5

< A pair of tokens for use with the nv-p2p.h Linux kernel interface

CU_POINTER_ATTRIBUTE_SYNC_MEMOPS = 6

< Synchronize every synchronous memory operation initiated on this region

CU_POINTER_ATTRIBUTE_BUFFER_ID = 7

< A process-wide unique ID for an allocated memory region

CU_POINTER_ATTRIBUTE_IS_MANAGED = 8

< Indicates if the pointer points to managed memory

CU_POINTER_ATTRIBUTE_DEVICE_ORDINAL = 9

< A device ordinal of a device on which a pointer was allocated or registered

CU_POINTER_ATTRIBUTE_IS_LEGACY_CUDA_IPC_CAPABLE = 10

< 1 if this pointer maps to an allocation that is suitable for ::cudaIpcGetMemHandle, 0 otherwise

CU_POINTER_ATTRIBUTE_RANGE_START_ADDR = 11

< Starting address for this requested pointer

CU_POINTER_ATTRIBUTE_RANGE_SIZE = 12

< Size of the address range for this requested pointer

CU_POINTER_ATTRIBUTE_MAPPED = 13

< 1 if this pointer is in a valid address range that is mapped to a backing allocation, 0 otherwise

CU_POINTER_ATTRIBUTE_ALLOWED_HANDLE_TYPES = 14

< Bitmask of allowed ::CUmemAllocationHandleType for this allocation

CU_POINTER_ATTRIBUTE_IS_GPU_DIRECT_RDMA_CAPABLE = 15

< 1 if the memory this pointer is referencing can be used with the GPUDirect RDMA API

CU_POINTER_ATTRIBUTE_ACCESS_FLAGS = 16

< Returns the access flags the device associated with the current context has on the corresponding memory referenced by the pointer given

CU_POINTER_ATTRIBUTE_MEMPOOL_HANDLE = 17

< Returns the mempool handle for the allocation if it was allocated from a mempool. Otherwise returns NULL.

CU_POINTER_ATTRIBUTE_MAPPING_SIZE = 18

< Size of the actual underlying mapping that the pointer belongs to

CU_POINTER_ATTRIBUTE_MAPPING_BASE_ADDR = 19

< The start address of the mapping that the pointer belongs to

CU_POINTER_ATTRIBUTE_MEMORY_BLOCK_ID = 20

< A process-wide unique id corresponding to the physical allocation the pointer belongs to

Trait Implementations

impl Clone for CUpointer_attribute_enum

fn clone(&self) -> CUpointer_attribute_enum

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CUpointer_attribute_enum

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for CUpointer_attribute_enum

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for CUpointer_attribute_enum

fn eq(&self, other: &CUpointer_attribute_enum) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
