The Intel ISH (Integrated Sensor Hub) driver `intel_ish_ipc` is loaded, but it only detects the proximity sensor. Diagnostic Output: 1. Kernel Modules: `intel_ish_ipc` and `hid_sensor_hub` are loaded. `hid_sensor_prox` is loaded (Proximity sensor detected). `hid_sensor_accel_3d` or similar accelerometer modules are NOT loaded/used. 2. IIO Devices (`/sys/bus/iio/devices/`): Only `prox` devices are present. No `accel` devices found. 3. Modinfo `intel_ish_ipc`: Firmware `intel/ish/ish_lnlm.bin` is listed as available/supported by the module. Expected Behavior: The accelerometer should be exposed as an IIO device (e.g., `iio:deviceX` with name `accel_3d`) to allow `iio-sensor-proxy` to handle screen rotation. Suspected Cause: Missing or incorrect ISH firmware mapping for this specific HP Lunar Lake device in the Linux kernel or `linux-firmware` package.
