I can remember eDP being special (iirc that is!), but it all boils down to whether it uses the CPU or PCH PLL. The configure failure (<a href="show_bug.cgi?id=89661#c16">comment 16</a>) seemed to be when we couldn't find a PLL to use. It seems like we have a handful of bogons in that code.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
