linux logo居中，小企鹅的数量问题

logo居中：
1、设置logo图片在屏幕中的位置
vi drivers/video/fbmem.c
找到"fb_show_logo_line"函数，把
image.dx = 0;
image.dy = y;

改为

#ifdef CONFIG_LOGO_LOWERPOWER_WARNING  /*no config*/
if(1 == get_battery_status()){
image.dx = (info->var.xres/2)-(logo->width)/2;
image.dy = (info->var.yres/2)-(logo->height)/2;
}else{
image.dx = 0;
image.dy = y;

}
#else
//image.dx = 0;
//image.dy = y;
image.dx = (info->var.xres/2)-(logo->width)/2; //by jiangdou
image.dy = (info->var.yres/2)-(logo->height)/2;//by jiangdou
#endif
image.width = logo->width;
image.height = logo->height;

2、可以忽略
vi drivers/video/console/fbcon.c
找到"fbcon_prepare_logo"函数，在
logo_height = fb_prepare_logo(info, ops->rotate);
后面加上
logo_height += (info->var.yres/2) - (206/2);

3st, 小企鹅的数量问题，这个和CPU的数量有关，小企鹅显示越多，CPU核心数越多！

修改一个

int fb_show_logo(struct fb_info *info, int rotate){int y;#ifdef CONFIG_LOGO_LOWERPOWER_WARNINGif(1 ==  get_battery_status()){y = fb_show_logo_line(info, rotate, fb_logo.logo, 0,     1);}else{y = fb_show_logo_line(info, rotate, fb_logo.logo, 0,     1);// num_online_cpus());  //jiangdou}#elsey = fb_show_logo_line(info, rotate, fb_logo.logo, 0,        1);// num_online_cpus());//jiangdou#endify = fb_show_extra_logos(info, y, rotate);return y;}#else
