+// Registry key that when enabled, will enable use of GPU firmware.
+//
+// Possible mode values:
+//  0 - Do not enable GPU firmware
+//  1 - Enable GPU firmware
+//  2 - (Default) Use the default enablement policy for GPU firmware
+//
+// Setting this to anything other than 2 will alter driver firmware-
+// enablement policies, possibly disabling GPU firmware where it would
+// have otherwise been enabled by default.
+//
+// Policy bits:
+//
+// POLICY_ALLOW_FALLBACK:
+//  As the normal behavior is to fail GPU initialization if this registry
+//  entry is set in such a way that results in an invalid configuration, if
+//  instead the user would like the driver to automatically try to fallback
+//  to initializing the failing GPU with firmware disabled, then this bit can
+//  be set (ex: 0x11 means try to enable GPU firmware but fall back if needed).
+//  Note that this can result in a mixed mode configuration (ex: GPU0 has
+//  firmware enabled, but GPU1 does not).
