librga-rockchip's Introduction

librga

RGA (Raster Graphic Acceleration Unit)是一个独立的2D硬件加速器,可用于加速点/线绘制,执行图像缩放、旋转、bitBlt、alpha混合等常见的2D图形操作。本仓库代码实现了RGA用户空间驱动,并提供了一系列2D图形操作API。

版本说明

RGA API 版本: 1.9.3

适用芯片平台

编译说明

Android Source Project

​ 下载librga仓库拷贝至android源码工程 hardware/rockchip目录,配置好编译环境后,执行mm进行编译,根据不同的Android版本将自动选择Android.mk或Android.bp作为编译脚本。

$ mm -j16

CMAKE

​ 本仓库示例代码支持CMAKE编译,可以通过修改toolchain_*.cmake文件以及编译脚本实现快速编译。

工具链修改

  • Android NDK(build for android)

​ 参考librga源码目录下toolchains/toolchain_android_ndk.cmake写法,修改NDK路径、Android版本信息等。

工具链选项 描述
CMAKE_ANDROID_NDK NDK编译包路径
CMAKE_SYSTEM_NAME 平台名,默认为Android
CMAKE_SYSTEM_VERSION Android版本
CMAKE_ANDROID_ARCH_ABI 处理器版本
CMAKE_ANDROID_NDK_TOOLCHAIN_VERSION 工具链选择(clang/gcc)
CMAKE_ANDROID_STL_TYPE NDK C++库的链接方式(c++_static/c++_shared)
  • Linux(buildroot/debian)

​ 参考librga源码目录下toolchains/toolchain_linux.cmake写法,修改工具链路径、名称。

工具链选项 描述
TOOLCHAIN_HOME 工具链目录
TOOLCHAIN_NAME 工具链名称

编译脚本修改

​ 修改samples目录或需要编译的示例代码目录下cmake_*.sh,指定toolchain路径。

编译选项 描述
TOOLCHAIN_PATH toolchain的绝对路径,即《工具链修改》小节中修改后的toolchain_*.cmake文件的绝对路径
LIBRGA_PATH 需要链接的librga.so的绝对路径,默认为librga cmake编译时的默认打包路径
BUILD_DIR 编译生成文件存放的相对路径

执行编译脚本

  • Android NDK(build for android)
$ chmod +x ./cmake_android.sh
$ ./cmake_android.sh
  • Linux(buildroot/debian)
$ chmod +x ./cmake_linux.sh
$ ./cmake_linux.sh

Meson

​ 本仓库提供了meson.build,buildroot/debian支持meson编译。单独编译可以使用meson.sh 脚本进行config,需要自行修改meson.sh 内指定install 路径,以及PATH等环境变量,cross目录下是交叉编译工具配置文件,也需要自行修改为对应交叉编译工具路径。

​ 执行以下操作完成编译:

$ ./meson.sh
