I left a comment explaining why we should rewrite this test as an i915 self test. Essentially reading the values of the powergating registers from the CPU is racy. These register only contain values after the GPU has run at least a single context. This test fails because we've waken up uncore, but no context has been run on the RCS, leaving the EUs still not powered on (hence 0 values).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
