https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=198936 Bug ID: 198936 Summary: Xorg consume 100% with XFCE after latest DRM2 changes Product: Base System Version: 11.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: freebsd-bugs@FreeBSD.org Reporter: hselasky@FreeBSD.org Created attachment 154848 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=154848&action=edit Patch suggestion Hi, Without the attached kernel patch(es), Xorg starts consuming alot of CPU and becomes very unresponsive and unusable. Using ktrace reveals that X-org is issuing DRM_IOCTL_MODE_GETCONNECTOR over and over again with no apparent reason. It doesn't happen when using a simple window manager like blackbox. I was not able to use XFCE4 (9-stable userland) with 11-current kernel at all, after the latest DRM2 kernel updates. It worked fine before the update. I'm not sure what is causing it. Going through the new DRM2 code revealed that a mode sorting function did not take all parameters like interlaced or not into account, causing the mode list to be reshuffelled every time a new mode scan was done. Not sure if Xorg cares about this though. I can test patches if you have other suggestions. --HPS -- You are receiving this mail because: You are the assignee for the bug.
