Title:
intel grafic i915 driver no power saving states rc6
Status in linux package in Ubuntu:
Confirmed
Bug description:
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.
Any idea what might go wrong there?
