Hi, Yes, Samsung likely developed custom firmware based on the Firmware Development Kit (FDK) provided by Inteland signed it. When the firmware is loaded and the file is detected to be incorrect, it will print the log “[ 4.430675] intel_ish_ipc 0000:00:12.0: ISH loader: cmd 2 failed 10”. The vendor can upstream their firmware binary to linux-firmware.git according to the naming rules mentioned in https://docs.kernel.org/hid/intel-ish-hid.html#vendor-custom-firmware-loading.
