zesDeviceEnumEngineGroups: zero engine groups for iGPU

[Anlarry]

I use zesDeviceEnumEngineGroups(zes_device_handle_t hDevice, uint32_t *pCount, zes_engine_handle_t *phEngine) to get the number of engine groups of iGPU on Lunar Lake. But the pCount result is zero. However, I can get 1 engine group for NPU.

GPU and NPU Driver Version queried by zesDeviceGetProperties are 30A96CBBF49E258B5705D4C and npu-linux-driver-ci-1.10.0.20241107-11729849322.

My OS is ubuntu-24.10, kernel version is 6.12.
