IGT (Intel GPU Tool) could commit the following planes during the test: kms_plane: The sub-tests pixel-format-* will create planes with size of 1 or 4512 pixels, these size will be rejected by the original mode configs. Adjust minimum and maximum value of both plane width and height. kms_cursor_crc: If cursor_width and cursor_height is not defined, IGT uses min_width and min_height as the limitation when creating cursor plane so sub-tests like cursor-rapid-movement will be skipped. Set cursor_width and cursor_height to 512 pixel can solve the problem.
