本文主要介绍在OpenHarmony上，基于RK3568移植开源GPU Mesa3D图形驱动，使用的基线版本是openharmony 的RK分支+kernel4.19+Weston。

注意：weston是老版本中使用的，新版中已使用renderservice替换。

1、获取openharmony rk分支版本代码

该基线版本是RK分支的OpenHarmony版本，选用此版本的原因是，该版本使能了闭源的GPU。

创建编译openharmony的docker，安装依赖，下载源码，以及编译

创建docker：
podman run --name hm-rk -it -v /home/test/22-01-30_rk /:/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.7 /bin/bash
git config --global user.name “test”
git config --global user.email “test@com.cn”
git config --global credential.helper store
安装依赖：
curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo
chmod a+x /usr/local/bin/repo
apt-get update && apt-get install -y binutils git git-lfs gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g+±multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z1-dev ccache libgl1-mesa-dev libxml2-utils xsltproc unzip m4 bc gnutls-bin python3.8 python3-pip ruby libssl-dev
pip3 install -i https://repo.huaweicloud.com/repository/pypi/simple requests
下载源码：
repo init -u https://gitee.com/openharmonyrk/manifest -b master -m rk.xml --no-repo-verify
repo sync -c
repo forall -c ‘git lfs pull’
编译：
bash build/prebuilts_download.sh
./build.sh --product-name rk3568 --ccache

编译成功，刷机后，能进入系统，但是没有图形，注意RK版本的代码本省不能进图形是正常的。

2、编译5.10内核

Mesa3D需要高版本内核支持，而RK分支使用的是4.19的内核，所以需要升级内核，当前开源鸿蒙中2022.1.10后主干代码支持kernel5.10，因此编译kernel5.10需要使用Master 1.10以后的代码版本，具体如下：

mkdir hm-master && cd hm-master
podman run --name hm-master -it -v /home/test/hm-master/:/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.7 /bin/bash
git config --global user.name “test”
git config --global user.email “test@.com.cn”
git config --global credential.helper store
curl -s https://gitee.com/oschina/repo/raw/fork_flow/repo-py3 > /usr/local/bin/repo
chmod a+x /usr/local/bin/repo
repo init -u https://gitee.com/openharmony/manifest.git -b master --no-repo-verify
repo sync -c
repo forall -c ‘git lfs pull’
bash build/prebuilts_download.sh
./build.sh --product-name rk3568 --ccache --build-target kernel

注意：文档中只有本小节，即编译510内核才需要使用主干1.10以后的代码版本，其它小节均使用的是RK分支版本代码。

1）修改DTS

2）修改config配置

cd out/kernel/src_tmp/linux-5.10
make menuconfig ARCH=arm64

在graphic support中启用panfrost，

Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

然后在Direct Rendering Manager取消选择Ignore drm ioctl permission，然后保存退出配置。

Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

保存配置，并退出。

使用新的.config配置覆盖rockchip_linux_defconfig配置，使用make-ohos.sh脚本编译时config才能生效，如下：

cp .config arch/arm64/configs/rockchip_linux_defconfig

3）修改drivers/gpu/drm/drm_ioctl.c

修改out/kernel/src_tmp/linux-5.10/drivers/gpu/drm/drm_ioctl.c搜索关键字DUMB，将0修改为DRM_RENDER_ALLOW, 如下：

4）编译

5）刷机

图中所示img全部使用新版内核中编译出来的img刷机，即master部分都需要刷入编译5.10内核出来的img，

3、编译Buildroot

编译环境：ubuntu20.04

1）下载代码

git clone https://gitee.com/xfan1024/oh-buildroot-mesa3d -b rpi3b
cd oh-buildroot-mesa3d
apt-get install cpio ruby -y

2）修改配置

make mesa3d_rpi3b_defconfig
make menuconfig ARCH=arm64

修改如下：

如果需要测试glmark2，还应该选中glmaster2

选中glmark2，然后保存退出，重新编译

3）编译

make -j8

4）刷机测试

在system分区刷入buildroot编译出来rootfs.ext2镜像，刷机成功后，在终端运行glmark2-es2-wayland，验证内核panfrost驱动和用户态panfrost驱动是否可以正常工作，具体如下：

mkdir /tmp/xdg
export XDG_RUNTIME_DIR=/tmp/xdg
weston --tty 1 &
glmark2-es2-wayland

4、重新编译rk分支

1）找到编译好的二进制文件

将通过buildroot编译出来的二进制文件拷贝到rk分支的device/rockchip/hardware/gpu/中，

output/target/usr/lib/libEGL.so.1  
output/target/usr/lib/libGLESv1_CM.so.1  
output/target/usr/lib/libGLESv2.so.2  
output/target/usr/lib/libgbm.so.1  
output/target/usr/lib/libglapi.so.0

2）修改rk分支代码对应的编译配置项

修改device/rockchip/rk3568/BUILD.gn

import("//build/ohos.gni")  
  
print("rk3568_group in")  
group("rk3568_group") {  
  deps = [

  ]  
}

mesa3d_common_prebuilts = [

3）重新编译

./build.sh --product-name rk3568 –ccache

4）刷机

System、vendor、userdata 3个分区刷入rk分支新编译出来的img，

Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

刷机成功后，能正常进入系统，图形也正常启动，使用中速度明显感觉快了很多，即使输入wifi密码也能成功。

5、问题

1）内核编译报错：

Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区
解决办法：

使用命令，

PRODUCT_PATH=“vendor/hihope/rk3568” ./make-ohos.sh TB-RK3568X0

2）内核刷机后进不了系统

把rk编译出来的img刷机后能进入系统，但是没有图形，把之前编译出来的rootfs.ext2和新编译出来的510内核boot_linux.img刷机后，串口显示如下：

Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

解决办法：

有两种办法，一是把新老boot_linux.img 解压开对比

Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

新老版中extlinux.conf对比发现都是类似的内容，唯一的区别就是有如TC031C的标识，串口输出中有找不到extlinux.conf.TC031C的打印

Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

把old中extlinux.conf.TC031C拷贝到新版中，并复制toybrick.dtb为toybrick.dtb.TC031C

cd new
cp toybrick.dtb toybrick.dtb.TC031C
cp …/old/extlinux.conf.TC031C ./

重新刷入新的boot_linux.img，正常进入系统。

二是图中所示img全部使用新版内核中编译出来的img刷机（推荐该办法）。

3）编译buildroot报错

编译报如下：
Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

解决办法：

删除output目录，修改编译参数重新编译

rm -rf output/
make -j8

4）编译rk报错undefined symbol: wl_egl_window_create

错误提示如下：

使用nm -D 或者 objdump -tT 确定 glEnable 在哪个库文件中定义

nm -D libGLESv2.so.2 |grep glEnable
000068fc T glEnable
00006918 T glEnableVertexAttribArray
00006934 T glEnablei

然后修改配置foundation/graphic/standard/frameworks/animation_server/BUILD.gn，增加对应的依赖，

+++ b/frameworks/animation_server/BUILD.gn  
@@ -116,6 +116,7 @@ ohos_executable("animation_server") {

编译成功。

6）刷机进入系统后图形起不来

在终端执行ps -ef|grep weston，如果没有weston，即weston没有起来，如下：
Openharmony之GPU Mesa3D移植一（weston 老框架）-鸿蒙开发者社区

原因则是weston.cfg配置中没有加入export LIBGL_DRIVERS_PATH /system/lib环境变量。

如果出现如下：

# ps -ef |grep weston

最终定位到third_party/weston/weston.cfg 配置问题，weston服务启动时不能添加–use-pixman参数，如果有该参数，需要删除该参数，一下是基于RK分支代码weston的修改：
