panfrost

panfrost integration for rockchip platform

rk356x Mali-G52

1. Linux kernel部分修改：

1.1 修改arch/arm64/boot/dts/rockchip/rk3568.dtsi中的gpu节点

gpu: gpu@fde60000 {
        compatible = "rockchip,rk3568-mali", "arm,mali-bifrost";
        reg = <0x0 0xfde60000 0x0 0x4000>;
        interrupts = <GIC_SPI 40 IRQ_TYPE_LEVEL_HIGH>,
                     <GIC_SPI 41 IRQ_TYPE_LEVEL_HIGH>,
                     <GIC_SPI 39 IRQ_TYPE_LEVEL_HIGH>;
        interrupt-names = "job", "mmu", "gpu";
        clocks = <&scmi_clk 1>, <&cru CLK_GPU>;
        clock-names = "gpu", "bus";
        operating-points-v2 = <&gpu_opp_table>;
        power-domains = <&power RK3568_PD_GPU>;                                                                                                          
        status = "disabled";
};

1.2 修改arch/arm64/configs/rockchip_linux_defconfig，启用panfrost驱动

CONFIG_DRM_PANFROST=y

1.3 重新编译linux kernel，烧写boot.img，从启动信息中确认panfrost驱动加载情况：

[    3.267980] panfrost fde60000.gpu: clock rate = 594000000
[    3.268023] panfrost fde60000.gpu: bus_clock rate = 200000000
[    3.269270] panfrost fde60000.gpu: mali-g52 id 0x7402 major 0x1 minor 0x0 status 0x0
[    3.269299] panfrost fde60000.gpu: features: 00000000,13de77ff, issues: 00000000,00000400
[    3.269322] panfrost fde60000.gpu: Features: L2:0x07110206 Shader:0x00000002 Tiler:0x00000209 Mem:0x1 MMU:0x00002823 AS:0xff JS:0x7
[    3.269341] panfrost fde60000.gpu: shader_present=0x1 l2_present=0x1
[    3.271985] [drm] Initialized panfrost 1.1.0 20180908 for fde60000.gpu on minor 0

2. 安装mesa

安装必要的软件包：

sudo apt install -y x11proto-core-dev xtrans-dev libpixman-1-dev libx11-dev libxkbfile-dev libxfont-dev nettle-dev systemd libudev-dev libdrm-dev libepoxy-dev mesa-common-dev nettle-dev libudev-dev libgbm-dev libepoxy-dev libxshmfence-dev libxcb-xinput-dev

2.1 编译 libdrm:

git clone https://gitlab.freedesktop.org/mesa/drm.git
cd drm
meson build --prefix=/usr/local
sudo ninja -C build install

2.2 编译 mesa:

git clone https://gitlab.freedesktop.org/mesa/mesa.git
cd mesa
git checkout -f mesa-24.0.0
meson -Dgallium-drivers=panfrost,kmsro -Dvulkan-drivers=panfrost -Dplatforms=x11 -Dprefix=/usr/local build
sudo ninja -C build install

2.3 编译 xserver:

git clone https://gitlab.freedesktop.org/xorg/xserver.git
cd xserver
git checkout -f xorg-server-21.1.3 -b xorg-server-21.1.3
meson build -D prefix=/usr/local -D glamor=true
sudo ninja -C build install
sudo mkdir -p /var/local/log

2.4 编译 libinput:

git clone https://gitlab.freedesktop.org/xorg/driver/xf86-input-libinput.git
cd xf86-input-libinput 
meson build
sudo ninja -C build install

3. 系统配置信息修改

3.1 修改/usr/bin/X, 禁用libdrm-cursor。并修改Xorg启动路径

#export LD_PRELOAD=/usr/lib/aarch64-linux-gnu/libdrm-cursor.so.1
basedir=/usr/local/bin

3.2 修改/etc/ld.so.conf.d/00-aarch64-mali.conf文件，更新系统链接路径，优先加载mesa驱动

/usr/local/lib

修改完成后，执行以下命令更新共享库缓存，并重启机器：

ldconfig
