Today driver will enable HuC firmware authentication by GuC only on Gen11+ platforms as HuC firmware is required to unlock advanced video codecs in media driver. Legacy platforms with GuC/HuC are not affected by this change as for them driver still defaults to disabled(0) in auto mode.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
