https://bugs.freedesktop.org/show_bug.cgi?id=43487 --- Comment #1 from Rafał Miłecki <zajec5@xxxxxxxxx> 2011-12-03 03:23:42 PST --- ** LVDS corruption ** LVDS corruption consists of two problems: 1) Display is corrupted 2) Everything is moved (bottom and right parts of display are black) Ad 1 After booting (without HDMI connected) register 0x6818 is set to 0x00000640. When I connect HDMI, driver changes it to 0x00000580. I have no idea why does it happen, but it's source of the corruption. Setting it back with: avivotool regset 0x6818 0x00000640 removes corruption. I believe register is defined as: #define EVERGREEN_GRPH_PITCH 0x6818 With fglrx register 0x6818 is set to 0x640 all the time (with HDMI and without) Ad 2 After booting (without HDMI connected) register 0x6810 is set to 0x00000000. When I connect HDMI, driver changes it to 0x00142000. It's the source of moved display. Setting it back with: avivotool regset 0x6810 0x00000000 removes movement. I believe register is defined as: #define EVERGREEN_GRPH_PRIMARY_SURFACE_ADDRESS 0x6810 With fglrx register 0x6810 is set to 0 all the time (with HDMI and without) -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
