求助大神，RK3288 4.4怎么固定分辨率

在设置里可以固定分辨率啊，具体实现你可以看一下package/apps/Setting代码中的HdmiControllerActivity.java.如果你想第一次开机就默认好分辨率的话，你可以借鉴下我的代码，我的是设置自动获取分辨率的，你改成你对应的就好

应该是这里,hdmi插入后每次会调这个，改成不管怎样都设成default，只是我自己编译的kernel老是卡在启动画面不动。。
kernel/drivers/rockchip/hdmi/hdmi-lcdc.c

int hdmi_set_lcdc(struct hdmi *hdmi)
{
	int rc = 0;
	struct rk_screen screen;
//	printk("%s vic is %d autoset %d\n", __FUNCTION__, hdmi->vic, hdmi->autoset);
/**by xx
	if(hdmi->autoset)
		hdmi->vic = hdmi_find_best_mode(hdmi, 0);
	else
	hdmi->vic = hdmi_find_best_mode(hdmi, hdmi->vic);
//	printk("%s selected vic is %d\n", __FUNCTION__, hdmi->vic);
	if(hdmi->vic == 0)
		hdmi->vic = HDMI_VIDEO_DEFAULT_MODE;
*/
        hdmi->vic = HDMI_VIDEO_DEFAULT_MODE;
