飞腾FT2000 UEFI BIOS介绍

一. 编译环境

1. 安装VMware

2. 在VMware下安装Ubuntu(64 bit的需要把BIOS SETUP中的CPU的VT打开)

3. 交叉编译环境设置

1. Get the requirements A Universally Unique Id (UUID) header. Needed to build the EDK2 BaseTools.
   On Ubuntu:

	sudo apt-get install uuid-dev
1

2. Get the toolchain: Add Support for ARMGCC

   a. Get the arm-none-eabi Toolchain from Code Sourcery:
      cd $(WORKROOT) 
      wget http://www.codesourcery.com/sgpp/lite/arm/portal/package7813/public/arm-none-eabi/arm-2010.09-51-arm-none-eabi-i686-pc-linux-gnu.tar.bz2 
      tar xjf arm-2010.09-51-arm-none-eabi-i686-pc-linux-gnu.tar.bz2 
   b. Add the arm-none-eabi toolchain to your path
      Add Support for ARMLINUXGCC
      On a Ubuntu based-distribution, add the Linaro toolchain: 
        sudo add-apt-repository ppa:linaro-maintainers/toolchain 
        sudo apt-get update 
        sudo apt-get install gcc-arm-linux-gnueabi 
   c. 环境变量设置：
      切换到用户名下
      gedit /home/username/.bashrc
      添加
      export PATH=$PATH:/my_new_path
      执行
      source /home/username/.bashrc
  d. 输入aarch64-linux-gnu-gcc  -v  看看有没有版本信息，如果Command not found说明没有成功，或者你的虚拟机是64位的，需要在虚拟机能连接网络情况下，输入命令
 sudo apt-get install lib32z1 lib32stdc++6

4. 安装acpica编译ACPI table工具，

工具下载地址如下：

https://acpica.org/downloads

Why ACPICA?

With advanced power management (APM), power management is controlled by the BIOS independently of the operating system. When BIOS settings are exceeded, the BIOS turns off the screen or shuts down the hard drive. This creates an imperfect power management policy because it requires reimplementing the policy for each platform. Plug and play BIOS (PNPBIOS) specification is also unreliable.

With ACPI, power management moves from the BIOS to the operating system.

• An application can tell the operating system that the display is in use, and change its power policy accordingly.
• The operating system does not have the size limitation of the BIOS.
• The ACPI system firmware describes the system’s characteristics by placing data, organized into tables, into the main memory.

ACPICA code is fairly mature and implements the following:

• An AML (ACPI machine language) interpreter
• A table manager
• A namespace manager
• A resource manager
• Fixed and general purpose event support
• ACPI hardware support
• Support for the ACPI 5.0 specification

How It Works

• ACPICA defines and implements a group of software components for both 32-bit and 64-bit platforms.
• The architecture isolates all operating system dependencies to a relatively small translation or conversion layer (called the OS Services Layer)
• This isolation enables the bulk of the ACPICA code to be independent of any individual operating system.
• Requires no source code changes within the ACPICA code itself for new operating systems.

二. 编译BIOS

1. 代码根目录下面的批处理文件：build.sh

1. 编译前要先修改批处理文件的属性

	chmod +x build.sh
1

2. 第一次编译BIOS前要先编译basetool

	./build.sh init
1

3. 编译BIOS

	./build.sh r 编译release版BIOS
	./build.sh d 编译debug版BIOS

2. 整合BIOS image

1. 编译出来的PHYTIUM.fd是不可以直接烧录到主板上启动的，需要把科大提供的PBF头整合到BIOS前面。在上电时会先跑PBP，然后PBP再把BIOS复制到内存里面执行。
   PBP里面会初始化CPU、内存、PCI设备枚举和资源的分配以及AMD显卡的快速初始化。

2. 整合BIOS&PBF

export PBF_DIR=PhytiumPkg/pbf
./${PBF_DIR}/fiptool update --nt-fw PHYTIUM.fd ${PBF_DIR}/fip.bin --align 0x10000 --out fipnew.bin

fw=ft2000plus.fd
cp  ${PBF_DIR}/bl1.bin  $fw
dd  if=${PBF_DIR}/phyinit201707.bin of=$fw bs=1M  seek=1
dd  if=fipnew.bin  of=$fw  bs=1M  seek=2
1

执行完上面几个步骤之后生成的ft2000plus.fd就是最终烧录到主板的BIOS镜像

备注：
使用麒麟系统编译时需要把下面一行添加到build.sh里面：

	export  LANGUAGE=en_US.UTF-8
