** Description changed: - It seems that the i915 intel grafic driver in newer kernels (observed with 5.3) doesn't support energy saving. + It seems that the i915 intel graphic driver in newer kernels (observed with 5.3) doesn't support energy saving. How do I know that? Using powertop shows in idle tab the GPU - and this shows only : GPU power on 100% - no rc6 or deeper states are used. For some strange reason also the packet (summery?) shows in all states 0%, although I can observe the individual CPU cores are in different power states. The previous parameter enable_rc6 is not existing anymore. The other possible energy saving parameter enable_dc (if set to 1 or 2) results in log with: - setting dangerous option enable_dc - tainting kernel. + setting dangerous option enable_dc - tainting kernel. Any idea what might go wrong there?
