Bugzilla Automation <[email protected]> has asked freebsd-x11 (Nobody) <[email protected]> for maintainer-feedback: Bug 254446: graphics/drm-fbsd12.0-kmod: (radeon) drmn0: forbidden register 0x00028b90 at 1259 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=254446 --- Description --- OS: FreeBSD 12.2-STABLE HW: ATI Radeon HD 2400 PRO (RV610 GPU) After 12.2 upgrade, using the radeonkms module as shipped with the kernel, everything worked but I always got that libGL error: failed to load driver: radeon error for all applications using OpenGL, and in general, graphics appeared to be slow (e.g. when switching virtual screens, xterm took a noticable time to redraw a terminal window). Research indicated to use drm-fbsd12.0-kmod instead of the modules shipped with kernel. Initial attempts to use these resulted in the system quickly panicking after a few minutes of X11 operation. Rebuilt all modules (and GPU firmware) today, now it appears to be stable, and the dreadful "failed to load driver" message is gone. Overall graphics performance appears OK now. Most OpenGL applications to work well. However, cad/horizon-eda (which requires OpenGL 3.2 as minimum) triggers kernel errors, and yields garbage in its drawing areas. forbidden register 0x00028b90 at 1215 Invalid command stream ! Using the deprecated system-supplied kms modules, horizon-eda worked without problems. _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-x11 To unsubscribe, send any mail to "[email protected]"
