*ERROR* Unsupported linear format at Cluster0-win0

ARMer

RK3568 + forlinx desktop:

在桌面系统上移动鼠标的时候，串口打印 [drm:vop2_plane_atomic_check] *ERROR* Unsupported linear format at Cluster0-win0；
只要移动鼠标，就一直打印。
请问是什么问题？

我如上解决问题后，好像没有引起其它问题，请问可以继续这样用吧？

可以的，新版本主要是添加了gpu、vpu等的支持，优化原生can。

ARMer

问题解决了；
方法是dtsi文件中注释掉以下内容，编译内核，烧写boot.img：
#if 0
&vp0 {
        cursor-win-id = <ROCKCHIP_VOP2_CLUSTER0>;
};

&vp1 {
        cursor-win-id = <ROCKCHIP_VOP2_CLUSTER1>;
};
#endif

========分割线======
以上内容有cursor,win,vop2，CLUSTER0， 与出错的信息内容相关，尝试了一下，居然解决问题了；
不了解以上内容具体含义，估计可能屏幕光标显示有关。
烧写重启后dmesg如下：
forlinx@ok3568:~$ dmesg | grep 'vop2'

可以与上面有问题的dmesg比较一下。

目前把vop0与HDMI关联起来，显示相关这块edp，lvds，dsi1与vop0，vop1都是disabled。
        forlinx_control {
                status = "okay";
                video-hdmi = "hdmi";
                video-mipi-edp = "off";
                video-lvds = "off";
        };

&hdmi {
        status = "okay";
        rockchip,phy-table =
                <92812500  0x8009 0x0000 0x0270>,

&hdmi_in_vp0 {

};

&hdmi_in_vp1 {
        status = "disabled";
};

&route_hdmi {
        status = "okay";
        connect = <&vp0_out_hdmi>;
};
===============分割线==========
还有一个解决办法，“Unsupported linear format”这句出现在rockchip_drm_vop2.c文件中，注释掉这句，重新编译内核下载，串口终端也不会显示这个个错误了，只是觉得这方法掩耳盗铃。具体代码如下：
        /*
         * This is special feature at rk356x, the cluster layer only can support
         * afbc format and can't support linear format;
         */
        if (VOP_MAJOR(vop2_data->version) == 0x40 && VOP_MINOR(vop2_data->version) == 0x15) {
                if (vop2_cluster_window(win) && !vpstate->afbc_en) {
                        DRM_ERROR("Unsupported linear format at %s\n", win->name);
                        return -EINVAL;
                }
        }
//看注释，似乎是光标或者HDMI在cluster上显示格式不对，也许是厂家驱动支持的显示类型不够完善；

这篇文章是解决鼠标拖影，在dts中增加了cursor-win-id=<ROCKCHIP_VOP2_CLUSTER0> 之类的语句；
可见cursor-win-id真的是与鼠标相关；我注释以上内容后，鼠标显示不受影响。

友商fire.....fly论坛有相同的问题，挂了几个月，好像没解决......:L
希望那边的同学能看到这贴。
@forqs ，请问管理员，自己解决自己的问题，有奖励吗？？？:loveliness:

uboot选屏只开这一个屏幕输出试试

forqs您好：我只用到HDMI外接显示器，其余显示接口都没有用到。

1、 根据用户使用手册中，启动时串口终端按空格键，根本停不下来；启动后查询启动信息如下：

HDMI外显是1280X800

ARMer

按芯片内部结构 ，vp0，vp1，vp2配置1个给HDMI，其余禁止就可以了吧？
请问具体到dtsi文件中怎么配置？
dmesg显示启动过程就有错误提示了。
[drm:vop2_bind] Cluster0-win0 as cursor plane for vp0 好像跟鼠标光标有关系，移动鼠标的时候会打印那个错误信息，鼠标停止移动就不打印了。

问题解决了；
方法是dtsi文件中注释掉以下内容，编译内核，烧写boot.img：
#if 0

这个是ubuntuR2版本上会有的问题，您可以看下用户资料里更新的ubutuR3版用户资料，这个烧写后不会出现这个问题，并且适配了硬解码等，不过目前在R3上可能有些小问题，比如hdmi热插拔不显示，正在尝试解决。
