DellaOS引导程序篇 1、环境配置

这里环境位centos7（带图形界面）

1.1、centos7没网

cd /etc/sysconfig/network-scripts/
vim ifcfg-ens33

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_onLY=no
BOOTPROTO=dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=86312406-5cb4-4200-9903-2b7745ca4e97
DEVICE=ens33
onBOOT=yes

systemctl restart network

1.2、更新yum

sudo yum install wget -y
sudo wget -O /etc/yum.repos.d/CentOS-base.repo https://mirrors.tencent.com/repo/centos7_base.repo
sudo yum clean all
sudo yum makecache

安装依赖

sudo yum install gtk2 gtk2-devel libXt libXt-devel libXpm libXpm-devel SDL SDL-devel xorg-x11-server-devel nasm gcc-c++ glibc-headers libX11-devel libXrandr-devel lrzsz -y

1.3、zip

yum install -y unzip zip

1.4、安装git

yum -y install git

1.5、VPN（clash，需要在windows上安装过）

C:Usersxumeng03.config
上传到
/root/.config
订阅
wget https://mymonocloud.com/clash/457240/5K9yNAE6yMnc
mv 5K9yNAE6yMnc config.yaml
gunzip clash-linux-amd64-v1.8.0.gz

修改代理如下图

启动

./clash-linux-amd64-v1.8.0

1.6、edk2-UDK2018

安装依赖

yum install build-essential git uuid-dev iasl nasm libuuid-devel

拉取分支

#git clone https://github.com/tianocore/edk2.gitgit clone git://github.com/tianocore/edk2.git

切换分支

cd edk2/git checkout UDK2018

编译

make -C baseTools/baseTools/BuildEnv. ./edksetup.sh

修改配置文件

vim Conf/target.txt

target.txt

# ACTIVE_PLATFORM       = Nt32Pkg/Nt32Pkg.dsc
ACTIVE_PLATFORM = OvmfPkg/OvmfPkgX64.dsc

TARGET                = DEBUG

# TARGET_ARCH           = IA32
TARGET_ARCH = X64

TOOL_CHAIN_CONF       = Conf/tools_def.txt

# TOOL_CHAIN_TAG        = MYTOOLS
TOOL_CHAIN_TAG = GCC48

BUILD_RULE_CONF = Conf/build_rule.txt

git submodule update --init --recursivebuild

2、编译执行UEFI Shell 2.1、U盘分区处理

[root@localhost ~]# fdisk -l /dev/sdb

Disk /dev/sdb: 31.0 GB, 31037849600 bytes, 60620800 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x05353b8c

   Device Boot      Start         End      Blocks   Id  System
/dev/sdb1               1  4294967295  2147483647+  ee  GPT
[root@localhost ~]# ls /dev/sdb*
/dev/sdb  /dev/sdb1  /dev/sdb2

2.2、拷贝UEFI应用程序

[root@localhost ~]# mount /dev/sdb1 /mnt/
[root@localhost ~]# mkdir -p /mnt/EFI/BOOT
[root@localhost ~]# cp /root/Desktop/dellaOS/edk2/Build/OvmfX64/DEBUG_GCC48/X64/Shell.efi /mnt/EFI/BOOT/BOOTx64.EFI
[root@localhost ~]# sync
[root@localhost ~]# umount /mnt/

2.3、新建虚拟机

2.4、配置UEFI固件

cd	显示或修改当前目录
cls	清除终端输出信息或改变前景/背景颜色
cp	复制一个或多个文件或目录到目标路径
date	显示或设置当前系统日期
del	rm命令的别名
devices	显示UEFI驱动的设备管理列表
devtree	显示UEFI驱动的设备管理树
dh	显示UEFI环境的设备句柄
dir	ls命令的别名
dmem	显示系统、IO寄存器、PCI/PCIe配置空间或设备内存空间信息
dmpstore	管理所有UEFI环境变量
drivers	显示UEFI环境里的UEFI驱动列表信息
echo	显示脚本中的打印信息
edit	文件的全屏编辑器
exit	退出UEFI Shell或当前脚本
help	显示UEFI Shell的内建命令列表
mem	dmem命令的别名
memmap	显示UEFI环境维护的内存映射
mkdir	创建一个或多个新的目录
mm	显示或修改内存/MMIO/IO/PCI/PCIe地址空间
mode	显示或修改终端设备的显示模式
mv	移动一个或多个文件到目标路径
pci	显示PCI设备列表或PCI/PCIe配置空间
reset	重启系统
rm	删除一个或多个文件或目录
setsize	调整文件大小
time	显示或设置当前系统时间

ver	显示UEFI Shell和固件的版本信息
vol	显示文件系统的容量信息

3、UEFI下的 ”Hello，world！“ 3.1、helloworld.c

#include 

EFI_STATUS EFIAPI UefiMain(IN EFI_HANDLE ImageHandle,IN EFI_SYSTEM_TABLE *SystemTable)
{
    SystemTable->ConOut->OutputString(SystemTable->ConOut,L"Hello Worldn");
    return EFI_SUCCESS;
}

所有的UEFI程序都要包含头文件Uefi.h，Uefi.h定义了UEFI基本数据类型及核心数据结构
UEFI标准应用程序的入口函数为是UefiMain，入口函数名由工程文件UefiMain.inf指定，入口函数的函数名可以变化但函数签名（即返回值类型和参数列表类型）不能变化
大部分UEFI程序的返回值都为EFI_STATUS，本质为无符号长整数
EFI_SUCCESS为预定义常量，值为0
ImageHandle和SystemTable为参数，ImageHandle表示模块自身加载到内存后生成的Image对象，SystemTable是程序与UEFI内核交互的桥梁，是UEFI内核中一个全局的结构体
字符串“Hello World”前面的大写字母L 用于通知编译器字符串必须按照宽字符保存
向标准输出设备打印字符串是通过SystemTable的ConOut提供的服务完成的。ConOut是EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL的一个实例。而EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL的主要功能是控制字符输出设备。向输出设备打印字符串是通过ConOut 提供的OutputString服务完成的。该服务（函数）的第一个参数是This指针，指向EFI_SIMPLE_TEXT_OUTPUT_PROTOCOL实例(此处为ConOut)本身;第二个参数是Unicode字符串。关于Protocol和This指针将在第4章详细介绍。简而言之，这条打印语句的意义就是通过SystemTable →ConOut →OutputString服务将字符串L“HelloWorld”打印到SystemTable →ConOut所控制的字符输出设备

想要编译UEFI应用程序源代码，必须在源文件所在目录下创建一个后缀名为.inf的工程信息文件

3.2、helloworld.inf

[Defines]
  INF_VERSION                    = 0x00010005
  base_NAME                      = helloworld
  FILE_GUID                      = 6987936E-f301-4a63-9661-fc6030dcc899
  MODULE_TYPE                    = UEFI_APPLICATION
  VERSION_STRING                 = 1.0
  ENTRY_POINT                    = UefiMain

[Sources]

	Cpu32.c
[Sources .x64]
	Cpu64.c

3.2.3、[Packages]块

块内每一行列出一个文件，文件使用相对路径，若[Sources]块内列出了源文件，则在[Packages]块必须列出MdePkg/MdePkg.dec，并将其放在本块的首行

示例

[Packages]
  MdePkg/MdePkg.dec

3.2.4、[LibraryClasses]块

语法格式
