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: 1.10.3

适用芯片平台

克隆下载源码

源码地址：https://github.com/tsukumijima/librga-rockchip

cd ~
git clone https://github.com/tsukumijima/librga-rockchip.git
cd librga-rockchip
nano toolchains/toolchain_linux.cmake

修改toolchain_linux.cmake如下

#SET(TOOLCHAIN_HOME "/home/yqw/workspace/linux/common/prebuilts/gcc/linux-x86/aarch64/gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu")
#SET(TOOLCHAIN_NAME "aarch64-rockchip1031-linux-gnu")SET(TOOLCHAIN_HOME "/usr")
SET(TOOLCHAIN_NAME "aarch64-linux-gnu")# this is required
#SET(CMAKE_SYSTEM_NAME Linux)# specify the cross compiler
SET(CMAKE_C_COMPILER ${TOOLCHAIN_HOME}/bin/${TOOLCHAIN_NAME}-gcc)
SET(CMAKE_CXX_COMPILER ${TOOLCHAIN_HOME}/bin/${TOOLCHAIN_NAME}-g++)# where is the target environment
SET(CMAKE_FIND_ROOT_PATH  ${TOOLCHAIN_HOME})# search for programs in the build host directories (not necessary)
SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
# for libraries and headers in the target directories
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

说明：这一步是修改交叉编译工具的主目录和文件名，可以用find / -name gnu-gcc 查找到。

生成make文件

$ chmod +x ./cmake-linux.sh
$ ./cmake-linux.sh

生成编译目录build/build_linux，进入该目录编译

cd build/build_linux
make -j4
make install
