--- Comment #14 from Jani Nikula <jani.nikula at intel.com> ---
"options i915" means they'll get applied as module parameters for i915.

debug=14 is a module parameter for drm module.

log_buf_len is a kernel parameter, not a module parameter at all. It needs to
be set on the kernel command line.

The conf file you refer to is probably for modprobe. You could start off by
removing the options for i915 altogether, and add them to the kernel command
line. On the kernel command line module specific parameters are set using
modulename.parameter syntax, e.g. drm.debug=14.

You can adjust kernel parameters for each boot at the grub menu, or by editing
/etc/default/grub and running update-grub after that. At least on some distros.
