RK3588关于panthor驱动的移植

说明

除了gnome之外，用的GPU驱动都是arm官方的闭源驱动libmali，只支持openGL ES和openCL。
由于wayland方式需要openGL支持，而openGL ES仅仅是openGL的子集，所以官方驱动其实并不支持wayland方式。
也就是说，使用官方驱动的镜像都只能使用xorg的显示服务器。

主要是 Valhall(Mali-G57, Mali-G610 ...)支持

mali GPU 系列：Mali Midgard（T7xx/T8xx）、Bifrost（Gxx）、Valhall（G6x/G7x）。

到6.10就是合入主线内核，直接支持了。
“Arm Mali-G310、Mali-G510、Mali-G610 和 Mali-G710 GPU 的 Panthor 开源驱动程序将成为 Linux 6.10 的一部分 ”一致性测试在 Linux 6.10.0-rc1 下的 Rock5b 板上运行。

环境

我是debian12的文件系统

官方的驱动库

存放rk3588开源panthor驱动的镜像仓库：（并不好用）
[https://gitee.com/yuunnn-w/rk3588-panthor-v0.2#https://gitee.com/link?target=https%3A%2F%2Fgithub.com%2FWillzenZou%2Flinux-orangepi%2Freleases%2Ftag%2Frk3588-panthor-v0.2]

尝试自己移植

# 设置代理

export http_proxy=http://192.168.1.244:7890
export https_proxy=http://192.168.1.244:7890

git clone https://gitlab.freedesktop.org/panfrost/linux.git
git checkout panthor-next+rk3588
cp -rf drivers/gpu/drm/panthor ../../RK3588/xxx-RK3588-MB-kernel-6.1/kernel/drivers/gpu/drm/

make rockchip_linux_defconfig ARCH=arm64

查看两个分支的交点：
panthor-v3+rk3588
panthor-v5+rk3588
git merge-base panthor-v5+rk3588 panthor-v3+rk3588

就知道从哪里开始改的了。

5.10版本mesa/panfrost支持

自己移植还是没有成功

网上找到一个分享的移植的patch

地址：

打上之后，问题：

解决：

# 内核配置 
CONFIG_CPU_FREQ=y
CONFIG_ENERGY_MODEL=y
CONFIG_CPU_FREQ_GOV_SCHEDUTIL=y  # EAS 相关

kernel/power/energy_model.c 是 Linux 内核中与 能量模型（Energy Model, EM） 相关的核心实现文件，主要用于为系统中的设备（尤其是 CPU）提供能耗行为的抽象模型。

检查GPU驱动是否OK

# 驱动：
root@linaro-alip:~# sudo cat /sys/kernel/debug/dri/*/name
rockchip dev=display-subsystem unique=display-subsystem
rockchip dev=display-subsystem unique=display-subsystem
panthor dev=fb000000.gpu-panthor unique=fb000000.gpu-panthor

panthor dev=fb000000.gpu-panthor unique=fb000000.gpu-panthor
rknpu dev=fdab0000.npu unique=fdab0000.npu

正常日志：

mesa库

接下来就是文件系统的opengl接口配置了。

export http_proxy=http://192.168.1.244:7890
export https_proxy=http://192.168.1.244:7890

#配置apt源
root@linaro-alip:~# cat /etc/apt/sources.list
deb http://mirrors.ustc.edu.cn/debian bookworm main contrib
deb-src http://mirrors.ustc.edu.cn/debian bookworm main contrib

deb-src http://mirrors.ustc.edu.cn/debian/ bookworm-backports main contrib
deb http://ftp.cn.debian.org/debian trixie main

# 之后卸载mali官方的deb包

apt remove libmali-*
apt install aptitude

# 就是 https://packages.debian.org/source/trixie/mesa 下面的包

apt install libd3dadapter9-mesa libd3dadapter9-mesa-dev libegl-mesa0 libegl1-mesa-dev libgbm-dev libgbm1 libgl1-mesa-dri libglx-mesa0 libosmesa6 libosmesa6-dev mesa-common-dev mesa-drm-shim mesa-libgallium mesa-opencl-icd mesa-teflon-delegate mesa-va-drivers mesa-vdpau-drivers mesa-vulkan-drivers -y

检查

检查当前 GL 渲染器

glxinfo | grep "OpenGL renderer"

问题：
驱动加载成功但是运行glmark2失败。

桌面：

# 检查
ps aux | grep Xorg
# 重新安装高版本的
sudo apt list -a xserver-common xserver-xorg-core xserver-xorg-legacy
sudo apt install xserver-common xserver-xorg-core xserver-xorg-legacy
# 桌面的鼠标
apt install xserver-xorg-input-all  xserver-xorg-input-evdev xserver-xorg-input-libinput

解决：

glmark2性能检测

apt install glmark2-x11

看上图即可

Chrome浏览器检测

apt install -y chromium

安装之后，播放视频，top命令查看CPU占用率，一般是30-40%左右的。

PS 总结

内核patch还是比较好配置，主要是文件系统的mesa配置，用mesa调用opengl，直接用debian编译好的就行。
