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.
Written by the indexing model from the issue text.
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.
