Clock scaling appears to be working as expected and I haven't had any visual artifacts or crashes to speak of yet. Using "amdgpu.dc=1" alone didn't make a difference but, "amdgpu.dpm=1" made all the difference. Good work to everyone involved!</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
