Gem5 Simulator

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
