In linux kernel since version 5.1 (release Date: 2019-05-05)
By default, always enables the extra sanity checks (extra register
reads) around every mmio (register) access that will slow the system
down. This sets the default value of i915.mmio_debug to -1 and can
be overridden at module load.
Recommended for driver developers only.
If in doubt, say "N".
