本文主要介绍在OpenHarmony上，基于RK3568移植开源GPU Mesa3D图形驱动，使用openharmony v3.1-Release 版本，该版本使用了新框架，内核使用了kernel 5.10.79版本，并使用render_service替换了Weston。
1、下载源码
创建编译openharmony的docker，安装依赖，下载源码
mkdir oh31re
cd oh31re/
podman run --name hm-31re -it -v ./:/home/openharmony swr.cn-south-1.myhuaweicloud.com/openharmony-docker/openharmony-docker-standard:0.0.9 /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，并编译：
repo init -u https://gitee.com/openharmony/manifest.git -b refs/tags/OpenHarmony-v3.1-Release --no-repo-verify
repo sync -c
repo forall -c ‘git lfs pull’
bash build/prebuilts_download.sh
./build.sh --ccache --product-name rk3568
编译成功，刷机后，能进入系统，也能进入图形，当前版本使用的是闭源GPU驱动，所以使用起来也是很流畅的。
2、编译mesa 3D库
进入容器：
podman exec -it hm-31re bash
下载源码：
git clone https://gitee.com/openharmony-sig/third_party_mesa3d.git
安装依赖：
apt-get install -y meson cmake llvm
python3 -m pip install meson==0.62.0
python -m pip install --upgrade pip
pip install mako atomic markupsafe
编译依赖库expat：
./build.sh --ccache --product-name rk3568 --build-target expat
编译mesa 3D：
cd third_party_mesa3d/
python ohos/build_ohos.py /home/openharmony/ rk3568 /home/openharmony/third_party_mesa3d/
拷贝库文件到device/hihope/hardware/gpu
cp build-ohos/src/egl/libEGL.so.1.0.0 …/device/hihope/hardware/gpu/
cp build-ohos/install/lib/libGLESv1_CM.so.1.1.0 …/device/hihope/hardware/gpu/
cp build-ohos/install/lib/libGLESv2.so.2.0.0 …/device/hihope/hardware/gpu/
cp build-ohos/install/lib/libgbm.so.1.0.0 …/device/hihope/hardware/gpu/
cp build-ohos/install/lib/libglapi.so.0.0.0 …/device/hihope/hardware/gpu/
cp build-ohos/src/gallium/targets/dri/libgallium_dri.so …/device/hihope/hardware/gpu/
cp build-ohos/install/lib/dri/panfrost_dri.so …/device/hihope/hardware/gpu/
注意，使用编译mesa库需要把third_party_mesa3d放到openharmony源码中。
3、修改内核配置
1）修改内核dtb
修改out/kernel/src_tmp/linux-5.10/arch/arm64/boot/dts/rockchip/rk3568.dtsi适配开源panfrost，如下：

5、编译
./build.sh --ccache --product-name rk3568
6、刷机
刷机后，render_service正常起来了，图形也正常启动，panfrost驱动也正常，点击界面，流畅不卡顿。
7、问题
1）编译mesa库的时候报错ld.lld: error: unable to find library -lexpat
解决办法：
该问题是缺少依赖expat，需要编译expat
./build.sh --ccache --product-name rk3568 --build-target expat
2）编译mesa库的时候报错如下：
解决办法：
该问题是meson版本过低导致，升级该版本解决问题
python3 -m pip install meson==0.62.0
3）编译mesa库的时候报错如下：
解决办法：
该问题是缺少mako依赖，安装该包即可，具体如下：
python -m pip install --upgrade pip
pip install markupsafe
pip install mako
4）编译问题
移植完mesa驱动后，编译报错如下：
解决办法：
该问题原因主要是mesa3d库的软连接导致的，需要修改gn让软连接实体so，并且添加上so的软连接，具体参考第4节中6）修改device/hihope/hardware/gpu/BUILD.gn。
5）刷机后，能进系统，但是图形起不来
解决办法：
ps命令查看发现render_service 服务没有起来，判断是该服务导致的，
该问题是mesa3d库有问题，可能是使用的mesa3d库是ohos/build_wayland_and_gbm.py编译出来的，即使用老框架支持的，在新框架中需要使用ohos/build_ohos.py编译的mesa3d库，具体编译方法请参考第2节编译mesa 3D库。

export LUS_INCLUDE_PATH=/usr/include/python3.6:$CPLUS_INCLUDE_PATH
然后再执行如下命令：
source ~/.bashrc
最后重新安装atomic，安装成功。
