drm_display_mode.vdisplay = 1080;
drm_display_mode.vrefresh = 60;
drm_display_mode.hsync_start = 2008;
drm_display_mode.hsync_end = 2052;
drm_display_mode.htotal = 2200;
drm_display_mode.vsync_start = 1084;
drm_display_mode.vsync_end = 1089;
drm_display_mode.vtotal = 1125;
drm_display_mode.vscan = 0;
drm_display_mode.flags = 5;
drm_display_mode.clock = 148500;
framebuffer_info参数为：
framebuffer_info.framebuffer_width = 0;
framebuffer_info.framebuffer_height = 0;
framebuffer_info.fps = 60;
