// 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). | ||
