Also disabling the gpu reset is probably not a good idea since that will freeze the complete system if such a hang occurs. Rainer and I are testing with i915.enable_rc6=0 since several hours and for now - we did not have another hang. concerning your parameters: drm.debug=0 drm.vblankoffdelay=1 i915.semaphores=0 <- user per chip defaults (-1) is default i915.modeset=1 <- forces modesetting i915.use_mmio_flip=1 <- this is not documented i915.powersave=1 <- is the default i915.enable_ips=1 <- is the default i915.disable_power_well=1 <- is the default i915.enable_hangcheck=1 <- default i915.enable_cmd_parser=1 <- default i915.fastboot=0 <- default i915.enable_ppgtt=1 <- -1 (auto) is the default i915.reset=0 <- this is probably dangerous as the gpu won't be reset i915.lvds_use_ssc=0 <- default is auto i915.enable_psr=0 <- this is the default So no idea which one makes a difference. The semaphores most likely? I will also start testing with i915.semaphores=0 now.</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>
