I am trying to configure the i915 driver on my XPS 13 (9360) running Ubuntu 16.04 for better battery runtime.
I have created a kernel config file with this name:
Content of the file:
options i915 modeset=1 enable_rc6=1 enable_fbc=1 enable_guc_loading=1 enable_guc_submission=1 enable_huc=1 enable_psr=1 disable_power_well=0
I have restarted the machine and checked the driver parameters with this:
systool -v -m i915
This doesn't list my options in the "Parameters" section.
Seems like my options are not set to the driver at all (only the "enable_hangcheck" option with its "Y" default value).
What am I doing wrong?
