Lichee_RV学习系列—移植dhrystone
文章目录
一、CoreMark-Pro简介
它也是和dhrystone一样，是一个测试CPU处理能力的一个程序，俗称跑分，CPU能跑多少分，CPU的处理能力就多高。
它可以在8位到64位的CPU上运行，而且跑分的可信度比dhrystone要高。
CoreMark-Pro是一个先进的市场处理器测试基准，跑分可信度高。EEMBC CoreMark和CoreMarkPRO共同提供了涵盖从低端微控制器到高性能计算处理器的标准基准测试。EEMBC CoreMark PRO基准测试包含五个常见的整数工作负载和四个常见的浮点工作负载。
CoMark-Pro分别会生成9个测试文件，分别对于一下测试
cjpeg-rose7-preset.exe linear_alg-mid-100x100-sp.exe parser-125k.exe zip-test.exe
core.exe loops-all-mid-10k-sp.exe radix2-big-64k.exe
nnet_test.exe sha-test.exe
这些文件的测试内容包括：
- JPEG压缩
- ZIP压缩
- XML解析
- CoreMark版本的密集内存测试
- Radix-2 快速傅里叶变换（FFT）
- A simple neural-net
- Livermore循环基准测试的一个大大改进的版本
- LINPACK软件包导出的旋转高斯消去法
二、获取源码
详细的文档源码里面有，在docx目录中，简单的入门在官网github简介下面也有介绍，本文主要是参考github简介和core mark prou移植和xiaojie开源的代码去跑的
三、编译coremark-pro
1、配置coremark-pro
配置两个文件就行，一个是交叉工具链编译的文件，一个是操作系统配置的文件
首先我们需要先进入源码目录，进入配置文件的目录
cd util/make
复制交叉编译工具链的文件
cp gcc-cross-linux.mak gcc-cross-riscv.mak
复制操作系统配置
cp linux64.mak riscv64.mak
配置交叉工具 gcc-cross-riscv.mak文件，配置好TOOLS和TPREF变量即可，这两个你的是交叉编译工具链所在的位置
TOOLS = /home/allwinner/workspace/tina-D1-H/prebuilt/gcc/linux-x86/riscv/toolchain-thead-glibc/riscv64-glibc-gcc-thead_20200702
TPREF = riscv64-unknown-linux-gnu-
# File : util/make/gcc-cross-linux.mak

配置操作系统riscv64.mak文件
这里我们需要配置PLATFORM和TOOLCHAIN
PLATFORM=riscv64 #分别是存放文件的目录名称
TOOLCHAIN=gcc-cross-riscv #交叉编译工具链
# File: util/make/linux64.mak
# Optional specific files for specialized run and results extraction
PLATFORM=riscv64

endif

# Use this flag to define a command needed to run the image
#

RUN =
# Flag: RUN
# Use this flag to supply flags before the image name and parameters

ifeq ($(DO_PROFILE),yes)
RUN_FLAGS =

endif
#Flag: PLATFORM_DEFINES
# Use PLATFORM_DEFINES to set platform specific compiler flags. E.g. set the timer resolution to millisecs with TIMER_RES_DIVIDER=1000

# Define XCMD on command line to pass flag at run time to workloads, or here if you want to override the default in <util/make/common.mak>
#FLAG: COPY_DATA
# How should data be copied so that it is available for the executable?
# Common ways include:
# - scp <target_ip>:<target_dir>(if target allows ssh connection)
# - invoking a special command line tool to transfer the data
# - copy (for file systems that do not support links)
# - link (for file systems where a simple symbolic link will work)
COPY_DATA=cp -Ru --remove-destination
2、编译coremark-pro
回到源码目录
执行编译命令
make TARGET=riscv64 build
编译完成后，九个可执行文件保存在builds目录下，可执行文件在builds/riscv64/gcc-cross-riscv/bin中
如果是这个命令 make TARGET=linux64 XCMD='-c4' certify-all，将运行9个测试，但是前提是开发板中已经有编译工具链和perl脚本，Lichee Rv Docv中并没有，这里仅仅在虚拟机中简单运行跑一跑
下面是我跑的分

五、小问题
小问题就自己记录，以后如果还记得如何解决的话，会回来更新的
问题一：复制交叉编译工具链的文件gcc-cross-linux.mak，用这个编译出来的core.exe不能执行，出现一下错误，但是用gcc64.mak这个文件来配置交叉编译工具链编译的core.exe却能执行
root@MaixLinux:/mnt/gcc-cross-riscv/bin# ./core.exe
ERROR: ee_ptr_int is not a datatype that holds an int pointer!
ERROR: Please modify the datatypes in core_portme.h!
- Info: Starting Run...
Segmentation fault
问题二：用官方的源代码去编译，缺少cjpeg-rose7-preset.exe这个文件，但是使用gitee xiaojie 的代码去编译却没问题，我查看宏也是正常设置好的，不知道为啥
