// 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-

// 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).
