Linux Driver for LVDS Output of V2 Video Chip
Based on loongson 2F processor,the authors developed ETX motherboard.Using V2 video chip,this board integrates VGA and LVDS paired video outputs,which support VGA and LVDS video ports displaying at the same time,with resolution ratio reaching 1600×1200.The original source code of Linux video driver already implements VGA port display function,while doesnt support LVDS port display function very well.To realize LVDS display function of V2 video chip,the authors need to modify the video driver source code in Linux kernel.This paper enters into details of the optimization process for LVDS port display.
