線上安裝gem5並整合nvmain：

1 安裝Mercurial
整合NVMain到GEM5中需要用到一個原始碼控制管理工具：Mercurial

apt-get install mercurial

2 安裝GEM5

使用hg clone命令下載GEM5（推薦使用最新版本的GEM5）：

hg clone http://repo.gem5.org/gem5

配置GEM5的執行環境， 參考該教程。

3 配置hgrc檔案

3.1 開啟hgrc檔案：

vim hgrc

3.2 把以下內容加入到hgrc檔案中，並將相關配置（如：username，from）修改成自己的資訊：

[ui]
# Set
 
 the username you will commit code with
username=Your Name <[email protected]>
ssh = ssh -C
# Always use git diffs since they contain permission changes and rename info
[defaults]
qrefresh = --git
email = --git
diff = --git
[extensions]
# These are various extensions we find useful
# Mercurial Queues -- allows managing of
 
 changes as a series of patches
hgext.mq =
# PatchBomb -- send a series of changesets as e-mailed patches
hgext.patchbomb =
# External Diff tool (e.g. kdiff3, meld, vimdiff, etc)
hgext.extdiff =
# Fetch allows for a pull/update operation to be done with one command and automatically commits a merge changeset
hgext.fetch =
[email]
method
 
 = smtp
from = Your Name <your@email.address>
[smtp]
host = your.smtp.server.here

4 下載NVMain

4.1 註冊bitbucket賬號；

4.2 按照NVMain網站上的說明獲取NVMain的使用權；

4.3 進入GEM5根目錄，使用hg clone命令下載NVMain；

5 安裝NVMain補丁

5.1 進入GEM5根目錄；

5.2 Initialize queues in gem5:

hg qinit

5.3 Import the NVMain patch:

hg qimport -f ../nvmain/patches/gem5/nvmain2-gem5-10688+

注意：我這裡的gem5和nvmain是在同一級目錄。
5.4 Apply the patch:

hg qpush

6 編譯GEM5 with NVMain

scons EXTRAS=../nvmain ./build/X86/gem5.opt

7 用spec cpu 2006來測試：

./build/X86/gem5.opt ./configs/example/se.py -c ../../download/speccpu2006/benchspec/CPU2006/450.soplex/exe/soplex_base.gcc41-64bit -o ../../download/speccpu2006/benchspec/CPU2006/450.soplex/data/test/input/test.mps 

注意：這裡的spec cpu 2006路徑寫成自己的。
