官方網址: http://www.gem5.org/Main_Page

它是什麼呢? 官方的說明如下:
The gem5 simulator is a modular platform for computer-system architecture research, encompassing system-level architecture as well as processor microarchitecture.

你可以先看看底下的Video, 它介紹了Gem5運行過程以及最後跑起來的狀況:

首先要下載Gem5的系統模擬程式 (Gem5 Download)
它是使用hg指令下載, 因此你的系統必需有安裝mercurial套件.
(1)sudo apt-get install mercurial
(2)hg clone http://repo.gem5.org/gem5-stable
你也可以先去http://repo.gem5.org/gem5-stable看看過去開發的歷史狀況
下圖的參考過程:

載完之後, 你會看到下面的檔案資料

這個目錄的架構大約如下面的介紹:

The basic source release includes these subdirectories:
   - configs: example simulation configuration scripts
   - ext: less-common external packages needed to build gem5
   - src: source code of the gem5 simulator
   - system: source for some optional system software for simulated systems
   - tests: regression tests
   - util: useful utility programs and files

下載完gem5原始程式後, 就可以編譯gem5的執行檔出來了.
Gem5採用SCons作為其開發工具, 因此你除了需要先安裝編譯程之外還需要安裝SCons相關的東西.
(1)sudo apt-get install scons swig python python-dev zlib1g-dev m4 protobuf{-c,}-compiler libgoogle-perftools-dev g++ build-essential
(2)scons build/ARM/gem5.opt -j 20 <==這個是開始編譯Gem5.

編譯方式可分為gem5.debug, gem5.opt, gem5.fast, gem5.prof四種

下載所需要的系統映像檔
它目前有提供三種(1)ARM(2)X86(3)ALPHA, 我們先下載ARM的, 因為前面是編譯ARM的版本.
(1)下載ARM Full-System Files
wget http://www.gem5.org/dist/current/arm/aarch-system-2014-10.tar.xz

(2)先建個目錄, 進到這個目錄把aarch-system-2014-10.tar.xz解壓縮
mkdir aarch-system
cd aarch-system
tar vxf ../aarch-system-2014-10.tar.xz

使用Gem5系統模擬器把系統映像檔運行起來
這時要回到gem5-stable的目錄下
首先要先做一件事, 設定一個M5_PATH環境變數, 將它的內容設定到你的系統映像檔位置.
export M5_PATH=/home/stanley/aarch-system
當然你也可以使用如同影片裏的方法, 將這個export放到~/.bashrc裏去

接著就可以開始運行模擬了, 輸入下面的指令.
build/ARM/gem5.opt -d /tmp/output configs/example/fs.py

模擬的方式也可分為兩種
(1)Full System(FS)

For booting operating systems
Models bare hardware, including devices
Interrupts, exceptions, privileged instructions, fault handlers
Simulated UART output
Simulated frame buffer output

(2)Syscall Emulation(SE)

For running individual applications, or set of applications on MP
Models user-visible ISA plus common system calls
System calls emulated, typically by calling host OS
Simplified address translation model, no scheduling

執行過程如下:

上面這個是模擬器的訊息. 接下來我們要開一個新的terminal使用telnet連上這台機器
telnet 127.0.0.1 3456
然後你會看到開機訊息如下

接下來我們看看/tmp/output這個目錄下的東西, 共產生了四個檔案
config.ini及config.json是屬於Files describing the configuration
(1)config.ini - ini formatted file that has all the objects and their parameters
(2)config.json - json formatted file which is easy to parse for input into other simulators (e.g. power)
stats.txt屬於Statistics
(3)stats.txt
*.terminal屬於系統資訊輸出檔
(4)system.terminal - Serial port output from the simulation
