简易查看GPU硬件加速开启GPU硬件加速
(1) 启动桌面的浏览器加速配置脚本(2) 查看启动信息以及相关LOG(3) 开启RGA(4) libmali库的对应选择以及安装
简易查看GPU硬件加速系统的GPU glmark2是正常使用, chrome浏览器正常启动，基本Chrome浏览器硬件加速就可以用起来。
查看方式：chrome://gpu 敲入地址栏可以查看gpu 支持的情况。（硬件加速：WebGL:Hardware accelerated WebGL2:Hardware accelerated）
GPU硬件加速未开启（WebGL:Disabled WebGL2:Disabled）
启动桌面的浏览器加速配置脚本，文件系统Chrome接口配置：
/etc/X11/xorg.conf.d/20-modesetting.conf
Section "Device"
Identifier "Rockchip Graphics"
Driver "modesetting"
Option "AccelMethod" "exa"
# Option "AccelMethod" "glamor"
Option "DRI" "2"
Option "FlipFB" "none"
Option "NoEDID" "true"
(2) 查看启动信息以及相关LOG
上面Chrome接口配置显示使用exa进行GPU硬件加速，查看LOG（路径：/var/log/Xorg.0.log,/var/log/Xorg.0.log.old）
[ 12.503] (II) modeset(0): Using internal exa [ 12.509] (EE) modeset(0): exa initialization failed
kernel的rga没有开启,导致出错（无法启动GPU硬件加速）。
(3) 开启RGA使用RGA进行加速步骤：
先打开RGA进行GPU加速，再选择是用exa还是glamor方式进行GPU的硬件加速。
内核设备树配置GPU打开：
&gpu {
status = "okay";
mali-supply = <&vdd_gpu>;
};
改设备树：
// rga: rga@ff920000 {
// compatible = "rockchip,rk3288-rga";
// reg = <0x0 0xff920000 0x0 0x180>;
// interrupts = ;
// clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA>;
// clock-names = "aclk", "hclk", "sclk";
// power-domains = <&power RK3288_PD_VIO>;
// resets = <&cru SRST_RGA_CORE>, <&cru SRST_RGA_AXI>, <&cru SRST_RGA_AHB>;
// reset-names = "core", "axi", "ahb";
// status = "disabled";
// };
rga: rga@ff920000 {
compatible = "rockchip,rga2";
reg = <0x0 0xff920000 0x0 0x180>;
interrupts = ;
resets = <&cru SRST_RGA_CORE>, <&cru SRST_RGA_AXI>, <&cru
SRST_RGA_AHB>;
reset-names = "core", "axi", "ahb";
clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA>;
clock-names = "aclk_rga", "hclk_rga", "clk_rga";
dma-coherent;
status = "okay";
};
或者在rk3288_linux.dtsi下添加
&rga {
compatible = "rockchip,rga2";
clocks = <&cru ACLK_RGA>, <&cru HCLK_RGA>, <&cru SCLK_RGA>;
clock-names = "aclk_rga", "hclk_rga", "clk_rga";
assigned-clocks = <&cru ACLK_RGA>, <&cru SCLK_RGA>;
assigned-clock-rates = <300000000>, <300000000>;
status = "okay";
};
配置完设备树后，将内核编译重新烧写
在/dev下生成rga节点
root@linaro-alip:/dev# ls -l rga crw-rw---- 1 root video 10, 52 Feb 14 18:11 rga
打开桌面浏览器，报错：
mali ffa30000.gpu: Stride passed to job_submit doesn't match kernel
文件系统里面的libmali库与内核对不上（第一方法：可能是版本问题，换高版本内核），查看启动信息中
[ 0.000000] Linux version 4.4.143 (root@ubuntu) (gcc version 6.3.1 20170404 (Linaro GCC 6.3-2017.05) ) #425 SMP Wed Apr 21 15:42:44 CST 2021 [ 7.729227] I : [File] : drivers/gpu/arm/mali400/mali/linux/mali_kernel_linux.c; [Line] : 417; [Func] : mali_module_init(); svn_rev_string_from_arm of this mali_ko is '-2cda2e6', rk_ko_ver is '5', built at '14:39:09', on 'Apr 21 2021'.[ 7.729536] Mali: Mali device driver loader
第二方法：换Mali安装包
(4) libmali库的对应选择以及安装libmali库是Chrome浏览器打开调用驱动底层的接口，没有对应可能打开会报上面的错误或者打不开浏览器
正常Mali驱动是r14或r18的版本 对应debian10才能跑起来。
Mali安装包在SDK debian/packages/armhf/libmali/libmali-midgard-t76x-r14p0-r*
板子里 debian/binary/packages/libmali
也可在这下载不同版本的Mail安装包
查看核心板使用的gpu型号确定使用的Mali安装包：
root@linaro-alip:/dev# cat /sys/devices/platform/*gpu/gpuinfo Mali-T76x 4 cores r1p0 0x0750
查看目前板子里使用的Mali版本：

使用的是libmali-midgard-t76x-r18p0-r1p0-x11_1.9-1_armhf.deb版本太高出现上面的报错
降低版本：libmali-midgard-t76x-r14p0-r1p0-x11_1.9-1_armhf.deb

可以查出更改为libmali-midgard-t76x-r14p0-r1p0-x11.so版本
重新打开浏览器，chrome://gpu 敲入地址栏可以查看gpu 支持的情况。（硬件加速：WebGL:Hardware accelerated WebGL2:Hardware accelerated）
OK！！
