一、优化启动时间的流程

1、系统启动流程：先使用nxp提供的系统方案启动系统。分析系统启动流程。优化启动时间工作在验证系统必须功能正常的前提下进行。系统可以独立下载源码进行编译，也可以通过yocto工程构建。

本次优化启动时间的优化目标为冷启动到进入界面的启动时间为3秒。

2、优化思路

二、启动快速启动裁剪原则

从优化的最后一步开始进行优化
先不要一开始就裁剪掉那些可以帮助我们判断和测量那些组件可以优化的工具和模块
先从应用程序开始优化
可以先简化systemd，移除不必要的服务。若是使用BusyBox，则减少启动脚本加载的命令和启动的进程，尽量减少启动应用程序所占用的时间。
下一步就是简化和优化kernel，内核模块裁剪，去除调试功能，裁剪不必要驱动
再然后才是bootloader优化。这时候内核优化应该已经接入尾声，而且，bootargs应该是一个定值。

三、测量启动时间的方法

在优化工作下，总是需要各种各样的启动时间测量工具，以及分析工具。让自己的优化时间工作高效快速

1. 串口终端工具：grabserial

这是一个python开源工具，可以在每行串口输出追加时间戳。在打印数据前加时间戳，优势是可以从进入bootloader就开始测量启动时间，而且不会影响系统启动的流程。当然也有缺点，就是不准确，而且不能够测量Power up ssequence时间。
使用grabserial：grabserial工具会从第一个节后到的字符开始计算，并没有统计到Power up ssequence时间。要统计Power up ssequence时间，可以示波器一个通道测量Power引脚，一个通道测量TXD引脚。然后测量两者时间差。达到测量Power up ssequence时间的目的。

Ubuntu16.04安装：

获取链接：http://elinux.org/Grabserial

安装grabserial

$ tar xzvf grabserial-1.9.3.tar.gz
$ cd grabserial-1.9.3/
$ sudo python setup.py install

若出现问题：

$ sudo python setup.py install
[sudo] l 的密码：
Traceback (most recent call last):File "setup.py", line 5, in <module>from setuptools import setup
ImportError: No module named setuptools

则安装：setuptools，然后在回滚之前的grabserial流程。

wget --no-check-certificate https://pypi.python.org/packages/source/s/setuptools/setuptools-12.0.3.tar.gz#md5=f07e4b0f4c1c9368fcd980d888b29a65
tar xvf setuptools-12.0.3.tar.gz
cd setuptools-12.0.3
sudo python setup.py install

使用grabserial

 sudo grabserial -d /dev/ttyUSB0 -t -e 20

2. dmesg命令分析kernel启动

dmesg可以输出启动启动的打印信息，其信息输出可以通过各种工具加工成图形表格，有助于帮助我们分析，系统在启动的时候到底花了多少时间在哪一些事情上。

dmesg使用准备工作

配置内核：增大log缓冲区

$ make menuconfig> General setup ─────────────────────────────────────────────────│ │ (16) Kernel log buffer size (16 => 64KB, 17 => 128KB)  │ │  │ │ (16) CPU kernel log buffer sizecontribution (13 => 8 KB, 17 => 128KB) │ │

bootargs配置：

setenv console 'ttymxc0,115200 earlycon=ec_imx6q,0x30860000,115200 initcall_debug printk.time=1'

使用kernel/scripts下的bootgraph.pl脚本生成图形

准备dmesg.log

$ dmesg > dmesg.log

生成bootgraph.svg，不好看，不直观。

$ cat dmesg.log | perl bootgraph.pl > bootgraph.svg

编写dmesg-initcall.pl脚本和FlameGraph生成图形
dmesg-initcall.pl脚本会调用到kernel/scripts下的bootgraph.pl脚本，算是一种改进版。

dmesg-initcall.pl脚本

获取FlameGraph

$ git clone https://github.com/brendangregg/FlameGraph.git

生成linux-boot-flamegraph.svg

cat dmesg.log | perl dmesg-initcall.pl > boot-initcall.log
cat boot-initcall.log | ./FlameGraph/flamegraph.pl > linux-boot-flamegraph.svg

生成linux-boot-gnuplot.svg直方图

准备linux-boot.gnuplot脚本

set terminal svg size 800,300 fsize 4
set output 'linux-boot-gnuplot.svg'
set style data histograms
set style histogram clustered gap 1 title offset character 0, 0, 0
set style fill solid 0.4 border
set xtics rotate by -45
set boxwidth 0.9 absolute
plot './boot-initcall.log' using 2:xticlabels(1)

安装gnuplot-x11

$ sudo apt-get install gnuplot-x11

生成linux-boot-gnuplot.svg

$ gnuplot < linux-boot.gnuplot

生成linux-boot-histogram.svg

准备TinyDrow

$ git clone https://github.com/tinyclub/tinydraw.git

生成linux-boot-histogram.svg

$ ./tinydraw/histogram/histogram.sh boot-initcall.log > linux-boot-histogram.svg

6. 统一生成所有svg

#!/bin/bash
cat dmesg.log | perl bootgraph.pl > bootgraph.svgcat dmesg.log | perl dmesg-initcall.pl > boot-initcall.log
cat boot-initcall.log | ./FlameGraph/flamegraph.pl > linux-boot-flamegraph.svggnuplot < linux-boot.gnuplot./tinydraw/histogram/histogram.sh boot-initcall.log > linux-boot-histogram.svgrm boot-initcall.log
mv *.svg /mnt/hgfs/D/

4、使用systemd-analyze分析systemd启动

$ systemd-analyze plot > systemd.svg

nxp提供源码编译启动分析

启动时间记录：下面是nxp出厂时的启动信息。做个记录。不要往下滑了…
好长。。。
这些信息可以利用上面的工具生成图表，容易分析。
这里截取关键部分分析：
