cuda.bindings._v2.driver.ExternalSemaphoreWaitFlags

class cuda.bindings._v2.driver.ExternalSemaphoreWaitFlags(value: int)

Flags for ExternalSemaphoreWaitParams_v1.flags_ (CUDA_EXTERNAL_SEMAPHORE_WAIT_*).

SKIP_NVSCIBUF_MEMSYNC: 2

When the flags parameter of CUDA_EXTERNAL_SEMAPHORE_WAIT_PARAMS contains this flag, it indicates that waiting on an external semaphore object should skip performing appropriate memory synchronization operations over all the external memory objects that are imported as CU_EXTERNAL_MEMORY_HANDLE_TYPE_NVSCIBUF, which otherwise are performed by default to ensure data coherency with other importers of the same NvSciBuf memory objects.
