ICL Mipi uses dual link mipi which requires DDIA and DDIB IO to be powered on. As dual link MIPI using the DDIB IO, I915 driver gets a reference count of power well PG3 which enables PG3 power well and fails the IGT lpsp test. With reference to ICL Power Well HLD document, we don't need to turn on PG3 for MIPI DSI dual link output . Impact : Power leakage from PG3. Action : Get B.Spec updated with PG3 requirement for MIPI DSI dela link output followed by change in i915 driver.</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>
