  • Exposes NPU-native topology, clock, timestamp frequency, on-chip SRAM, and compiler capability information that has no clean analogue in the GPU-oriented base ze_device_properties_t struct.

  • compilerVersion and maxOVOpsetVersionSupported describe the compiler bundled with the driver, and report identical values for every device reported by a given driver instance.

  • The base ze_device_properties_t fields remain populated on NPU devices for backward compatibility with consumers that predate this extension. New consumers should prefer the NPU-native fields exposed here.

  • Identity (vendorId, deviceId, subdeviceId, uuid, name), capabilities (flags, maxMemAllocSize, maxHardwareContexts, maxCommandQueuePriority), and host/global timestamp validity (timestampValidBits) continue to be sourced from the base ze_device_properties_t struct. NPU does not implement kernel timestamp APIs; kernelTimestampValidBits is 0 on NPU devices.
