I've changed /etc/modprobe.d/i915.conf like this:
--- a/modprobe.d/i915.conf

-options i915 i915_enable_rc6=1 i915_enable_fbc=1 lvds_downclock=1
+options i915 i915_enable_rc6=1 i915_enable_fbc=1 lvds_downclock=1
enable_ppgtt=0
and rebooted my laptop. Is there an easy way to check that the enable_ppgtt
option is correctly set to 0?
modinfo only shows me the default, not the current value:
$ sudo modinfo i915 | grep ppgtt
parm: enable_ppgtt:Override PPGTT usage. (-1=auto [default],
0=disabled, 1=aliasing, 2=full) (int)
Speaking of boot options, it looks like "i915_enable_rc6", "i915_enable_fbc"
and "lvds_downclock" aren't part of the "modinfo -p i915" output. I guess I
should remove them?
The first two however do exist without the "i915_" prefix but maybe I should
with the defaults?</pre>
