Ubuntu16.04 NVDLA环境搭建

Download the Virtual Simulator
$ git clone https://github.com/nvdla/vp.git
$ cd vp
$ git submodule update --init --recursive

Install Dependencies
1. Install required tools and libraries
$ sudo apt-get install g++ cmake libboost-dev python-dev libglib2.0-dev libpixman-1-dev liblua5.2-dev swig libcap-dev libattr1-dev
2. Download and install SystemC 2.3.0
$ wget -O systemc-2.3.0a.tar.gz http://www.accellera.org/images/downloads/standards/systemc/systemc-2.3.0a.tar.gz
$ tar -xzvf systemc-2.3.0a.tar.gz
$ cd systemc-2.3.0a
$ sudo mkdir -p /usr/local/systemc-2.3.0/
$ mkdir objdir
$ cd objdir
$ ../configure --prefix=/usr/local/systemc-2.3.0
$ make
$ sudo make install
如果遇到make install没有安装到制定目录的问题，查看Makefile中prefix变量赋值
prefix = /usr/local/systemc-2.3.0


3. Download and build NVDLA CMOD
$ git clone https://github.com/nvdla/hw.git
$ cd hw
$ make
如果遇到make install没有安装到制定目录的问题，查看Makefile中prefix变量赋值
prefix = /usr/local/systemc-2.3.0


3. Download and build NVDLA CMOD
$ git clone https://github.com/nvdla/hw.git
$ cd hw
$ make

这步按照提示输入对应工具路径，以下为参考：

DEFAULT_CPP := /usr/bin/cpp

DEFAULT_GCC := /usr/bin/g++

DEFAULT_PERL := /usr/bin/perl

DEFAULT_JAVA := /usr/bin/java

DEFAULT_SYSTEMC := /usr/local/systemc-2.3.0

DEFAULT_VERILATOR := verilator

DEFAULT_CLANG := clang

DEFAULT_PROJ := nv_full

$ tools/bin/tmake -build cmod_top

4. Cmake build

$ cd vp

$ cmake -DCMAKE_INSTALL_PREFIX=build -DSYSTEMC_PREFIX=/usr/local/systemc-2.3.0/ -DNVDLA_HW_PREFIX=/path/to/nvdla/hw -DNVDLA_HW_PROJECT=nv_full

$ make

编译vp中会遇到一些问题，参考以下解决方法

Can't locate YAML.pm/Tee.pm error
安装YAML.pm
downloading from url: http://search.cpan.org/CPAN/authors/id/T/TI/TINITA/YAML-1.24.tar.gz

make;
sudo make install


安装IO/Tee.pm

Deprecated Error

 template<class T> T * get_pointer(std::auto_ptr<T> const& p)
修改vp/CMakeLists.txt
注释下面三行：
# set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DSC_INCLUDE_DYNAMIC_PROCESSES -Wall -Werror ${AWS_FPGA_CFLAGS} ${TRACE_CFLAGS}")
# set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -DSC_INCLUDE_DYNAMIC_PROCESSES -Wall -Werror -DDEBUG_LOG=1 ${AWS_FPGA_CFLAGS} ${TRACE_CFLAGS}")
# set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -DSC_INCLUDE_DYNAMIC_PROCESSES -Wall -Werror ${AWS_FPGA_CFLAGS} ${TRACE_CFLAGS}")
添加如下：
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DSC_INCLUDE_DYNAMIC_PROCESSES -Wall  ${AWS_FPGA_CFLAGS} ${TRACE_CFLAGS}")
set(CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG} -DSC_INCLUDE_DYNAMIC_PROCESSES -Wall  -DDEBUG_LOG=1 ${AWS_FPGA_CFLAGS} ${TRACE_CFLAGS}")
set(CMAKE_CXX_FLAGS_RELEASE "${CMAKE_CXX_FLAGS_RELEASE} -DSC_INCLUDE_DYNAMIC_PROCESSES -Wall  ${AWS_FPGA_CFLAGS} ${TRACE_CFLAGS}")
将子目录下CMakeList.txt中的 CMAKE_CXX_FLAGS语句中的-Werror删除

Python库不是2.x，导致PyString_* 找不到

/home/bg193/works/nvdla/vp/libs/greenlib/greenscript/src/greenscript.cpp: In member function ‘void gs::script::GreenScriptModule::load(const char*)’:
/home/bg193/works/nvdla/vp/libs/greenlib/greenscript/src/greenscript.cpp:221:46: error: ‘PyString_AsString’ was not declared in this scope
       std::string s(PyString_AsString(path_py));
修改vp/libs/greenlib/CMakeLists.txt
  # set(EXTERNAL_INCLUDE_DIRS ${EXTERNAL_INCLUDE_DIRS} ${PYTHON_INCLUDE_DIRS})
  set(EXTERNAL_INCLUDE_DIRS ${EXTERNAL_INCLUDE_DIRS} "/usr/include/python2.7")


5.运行模拟器
VP编译完毕后，复制aarch64_toplevel到sw/prebuild/linux


修改aarch64_nvdla.lua

-kernel /home/bg193/works/nvdla/sw/prebuilt/linux/Image
-drive file=/home/bg193/works/nvdla/sw/prebuilt/linux/rootfs.ext4


在sw/prebuild/linux下执行：
$ export SC_SIGNAL_WRITE_CHECK=DISABLE
$ ./build/bin/aarch64_toplevel -c conf/aarch64_nvdla.lua

执行test测试
将vp/test目录下文件复制到sw/prebuild/linux,命令中r代表模拟器执行目录
# mount -t 9p -o trans=virtio r /mnt
# cd /mnt/tests/hello
# ./aarch64_hello修改vp/libs/greenlib/CMakeLists.txt
  # set(EXTERNAL_INCLUDE_DIRS ${EXTERNAL_INCLUDE_DIRS} ${PYTHON_INCLUDE_DIRS})
  set(EXTERNAL_INCLUDE_DIRS ${EXTERNAL_INCLUDE_DIRS} "/usr/include/python2.7")
