cuda.bindings._v2.driver.ExternalSemaphoreSignalFlags

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

Flags for ExternalSemaphoreSignalParams_v1.flags_ (CUDA_EXTERNAL_SEMAPHORE_SIGNAL_*).

SKIP_NVSCIBUF_MEMSYNC: 1

When the flags parameter of CUDA_EXTERNAL_SEMAPHORE_SIGNAL_PARAMS contains this flag, it indicates that signaling 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.
