Defined in /dvs/p4/build/sw/gpgpu/bin/x86_64_Linux_release/stub/cuda.h

struct CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1

External semaphore wait parameters.

Public Members

unsigned long long value

Value of fence to be waited on.

struct CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::[anonymous]::[anonymous] fence

Parameters for fence objects.

void *fence

unsigned long long reserved

union CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::[anonymous]::[anonymous] nvSciSync

Pointer to NvSciSyncFence.

Valid if CUexternalSemaphoreHandleType is of type CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC.

unsigned long long key

Value of key to acquire the mutex with.

unsigned int timeoutMs

Timeout in milliseconds to wait to acquire the mutex.

struct CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::[anonymous]::[anonymous] keyedMutex

Parameters for keyed mutex objects.

unsigned int reserved[10]

struct CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS_v1::[anonymous] params

unsigned int flags

Only when CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS is used to wait on a CUexternalSemaphore of type CU_EXTERNAL_SEMAPHORE_HANDLE_TYPE_NVSCISYNC, the valid flag is CUDA_EXTERNAL_SEMAPHORE_WAIT_SKIP_NVSCIBUF_MEMSYNC which indicates that while waiting for the CUexternalSemaphore, no memory synchronization operations should be performed for any external memory object imported as CU_EXTERNAL_MEMORY_HANDLE_TYPE_NVSCIBUF.

For all other types of CUexternalSemaphore, flags must be zero.
