+	bool "Always insert extra checks around mmio access by default"
+	default n
+	help
+	  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

+	depends on DRM_I915_DEBUG_GEM
+	help
+	  During development, we often only want the very first failure
+	  as that would otherwise be lost in the deluge of subsequent
+	  failures. However, more casual testers may not want to trigger
+	  a hard BUG_ON and hope that the system remains sufficiently usable
+	  to capture a bug report in situ.
+
+	  Recommended for driver developers only.
+
+	  If in doubt, say "N".
+
+config DRM_I915_ERRLOG_GEM
+	bool "Insert extra logging (very verbose) for common GEM errors"

+
+	  Recommended for driver developers only.

+	select FAULT_INJECTION
+	select PRIME_NUMBERS
+	select CRC32
+	help
+	  Choose this option to allow the driver to perform selftests upon
+	  loading; also requires the i915.selftest=1 module parameter. To
+	  exit the module after running the selftests (i.e. to prevent normal
+	  module initialisation afterwards) use i915.selftest=-1.
+

+	bool "Enable broken and dangerous selftests"

+	depends on BROKEN
+	default n
+	help
+	  This option enables the execution of selftests that are "dangerous"
+	  and may trigger unintended HW side-effects as they break strict
+	  rules given in the HW specification. For science.
+
+	  Recommended for masochistic driver developers only.
+
+	  If in doubt, say "N".
+
+config DRM_I915_LOW_LEVEL_TRACEPOINTS
+	bool "Enable low level request tracing events"
+	depends on DRM_I915

+	  Choose this option to turn on low level request tracing events.
+	  This provides the ability to precisely monitor engine utilisation
+	  and also analyze the request dependency resolving timeline.
+
+	  Recommended for driver developers only.
+
+	  If in doubt, say "N".
+
+config DRM_I915_DEBUG_VBLANK_EVADE
+	bool "Enable extra debug warnings for vblank evasion"
+	depends on DRM_I915
+	default n
+	help
+	  Choose this option to turn on extra debug warnings for the
+	  vblank evade mechanism. This gives a warning every time the
+	  the deadline allotted for the vblank evade critical section
+	  is exceeded, even if there isn't an actual risk of missing
+	  the vblank.
+
+	  Recommended for driver developers only.
+
+	  If in doubt, say "N".
+
+config DRM_I915_DEBUG_RUNTIME_PM
+	bool "Enable extra state checking for runtime PM"
+	depends on DRM_I915
+	default n
+	select STACKDEPOT
+	help
+	  Choose this option to turn on extra state checking for the
+	  runtime PM functionality. This may introduce overhead during
+	  driver loading, suspend and resume operations.
+
+	  Recommended for driver developers only.
+
+	  If in doubt, say "N"
