On latest Intel x86 CPUs, DMC firmware is required for the iGPU to reach
its lowest power states. If the driver cannot load it, it will print a
warning and unnecessarily make the iGPU draw a bit more power when idle.
GUC firmware (various "offload" mechanisms that deal with scheduling GPU
workloads) and HUC firmware (required for accelerated media codec
operations for HEVC/H.265) are probably more niche, but could also
provde useful for some - for example, when building an
Intel/OpenWrt-based security camera.
