If you grep the output of drm.debug=1 you see that drm_calc_timestamping_constants seems to reduce the frequency to 164250 kHz which is not sufficient for 3840x2160. In spite of debugging and backtracing both function calls (drm_calc_timestamping_constants and radeon_get_monitor_bpc) I have not found out by which function and in what way they are called. Please help.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
