操作：
1、安装gem5
参考我的gem5使用+se测试的文章
2、配置hgrc文件
vim ~/.hgrc
讲下面的信息复制到hgrc的文件夹中：修改（username，style，from）
[ui]
# Set the username you will commit code with
username=Your Name <your@email.address>
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 =
# Path to the style file for the M5 repository
# This file enforces our coding style requirements
style = /home/用户名/gem5/util/style.py
[email]
method = smtp
from = Your Name <your@email.address>
[smtp]
host = your.smtp.server.here
3、下载nvmain，放置在gem5目录下，nvmain见我的nvmain使用文章
4、安装NVMain补丁
（1）
hg qinit
出现下面信息没有关系
*** failed to import extension style from /home/jabingu/gem5/util/style.py: No module named file_types
abort: patch queue directory already exists
（2） Import the NVMain patch:
hg update 11688
hg qimport -f ./nvmain/patches/gem5/nvmain2-gem5-11688+
（3） Apply the patch:
hg qpush
5、编译
scons EXTRAS=nvmain ./build/X86/gem5.opt
6、测试
（1）se测试
./build/X86/gem5.opt ./configs/example/se.py -c ./tests/test-progs/hello/bin/x86/linux/hello
