This allows cpufreq governors to realize when the system becomes
non-CPU-bound due to GPU rendering activity, which will cause the
intel_pstate LP controller to behave more conservatively: CPU energy
usage will be reduced when there isn't a good chance for system
performance to scale with CPU frequ
