Description

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.

Research direction

Start by reproducing zesDeviceEnumEngineGroups on the reported Lunar Lake system and compare it with zesDeviceGetProperties for the GPU and NPU. The issue names no files or tests; completion requires establishing the expected iGPU engine-group behavior and confirming whether the result is an implementation defect or a driver limitation.
