cuda::experimental::places::locality_domain_native_raw_count

inline int cuda::experimental::places::locality_domain_native_raw_count(

int dev_id

)

Locality-domain count as answered by the driver, or 0 when the driver cannot answer (internal).

Queries CU_DEVICE_ATTRIBUTE_LOCALITY_DOMAIN_COUNT. A non-positive answer (old driver, attribute unsupported, …) is reported as 0 so callers in this header can select the whole-device degrade; the public locality_domain_count() never exposes it.
