// 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).
