Linux内核6.10提供了对没有mmu的riscv处理器工作在S模式下的内核的支持，本文介绍基于OpenSBI的linux no mmu的实现，供大家参考。

1、OpenSBI介绍

SBI：Supervisor Software Binary Interface 软件二进制接口

Linux内核工作在S模式下时，不能直接访问机器定时器。而系统的运行依赖于定时器，为了解决这个问题，需要通过SBI接口由工作在M模式下的SBI固件来提供访问定时器等功能。

SBI的实现方式有很多种，常见的包括BBL、OpenSBI、Xvisor、KVM、RustSBI、Diosix、Coffer。

文章将要介绍的OpenSBI应用实例采用了FW_JUMP方式的OpenSBI方案。

FW_JUMP类型的固件假设下一个引导阶段入口的地址是固定的，例如引导加载程序或操作系统内核，而不直接包含下一个阶段的二进制代码。

2、内核配置

在内核配置上，主要涉及到以下选项，也可以通过仓库中的hpmicro_HPM6800evk_defconfig来获取默认的配置。

仓库中还提供了基础的GPIO和PINMUX驱动，爱好者们可以通过修改设备树来实现LED和按键功能，而不用修改内核驱动代码。对于其他的外设的PINMUX配置，也可以通过修改设备树来完成。

3、Loader配置

由于HPM芯片启动时一般是以XIP的方式执行flash中的代码，所以需要一个loader程序来实现将OpenSBI、kernel、设备树等固件拷贝到其运行地址中。

除了搬移固件外，loader还需要做一些基础的初始化工作，包括sdram/ddr的使能，默认console的时钟和串口的pinmux配置等。

做完这些工作后，loader跳转至OpenSBI的入口函数，将系统交给OpenSBI来管理，接着OpenSBI在做完准备工作后，跳转至内核。

4、BuildRoot配置

单独编译loader、OpenSBI、Linux内核和文件系统并进行烧写是可行的，但是不是那么的方便，使用BuildRoot，我们可以方便的将这些固件整合到一起，一次性编译出整个固件。

4.1 loader的添加

首先将编写好loader固件上传到git服务器上。然后在buildroot的boot目录下创建一个文件夹hpmicro_loader,在其中添加两个新文件：Config.in和hpmicro_loader.mk

Config.in中主要是创建了一个Kconfig选项，用来选择是否要使能hpmicro_loader。使能后hpmicro_loader.mk会被加入到编译系统中。

在本文的实现中，loader是基于hpm_sdk进行编写的，其中将hpm_sdk作为submodule引入，所以在hpmicro_loader.mk中，不仅要将loader的仓库地址填入，还需要指定HPMICRO_LOADER_GIT_SUBMODULES = yes来让编译系统去初始化submodule，否则会缺失hpm_sdk文件。同时由于hpm_sdk是基于cmake构建系统的，还需要指定hpmciro_loader的构建系统为cmake：$(eval $(cmake-package))。由于hpm_sdk不支持源文件目录下直接编译，所以要指定HPMICRO_LOADER_SUPPORTS_IN_SOURCE_BUILD = no。再指定一些SDK编译需要的环境变量后，就可以顺利进行编译了。

编译结束后，通过后处理命令，将编译输出的bin文件，拷贝到genimage的工作目录，用于最终的镜像生成。

define HPMICRO_LOADER_INSTALL_TARGET_CMDS
dd if=/dev/zero of=$(@D)/buildroot-build/output/temp.bin bs=1 count=1024
cat $(@D)/buildroot-build/output/temp.bin $(@D)/buildroot-build/output/demo.bin > $(@D)/buildroot-build/output/opensbiloader.bin
$(INSTALL) -D -m 0644 $(@D)/buildroot-build/output/opensbiloader.bin $(BINARIES_DIR)/opensbiloader.bin
endef

4.2 Kernel版本的指定

Kernel的自定义版本指定功能是BuildRoot自带的，我们可以通过修改以下两个选项来指定Kernel的版本。

· 指定Kernel版本

BR2_LINUX_KERNEL_CUSTOM_TARBALL=y
BR2_LINUX_KERNEL_CUSTOM_TARBALL_LOCATION="$(call github,hpmicro,linux,7b088c87b6758e413bd316bf883438f7134f1e7f)/linux-7b088c87b6758e413bd316bf883438f7134f1e7f.tar.gz"

其中github,hpmicro,linux代表了仓库地址为github/hpmicro/linux.git,后边的7b088c87b6758e413bd316bf883438f7134f1e7f为指定的提交编号

也可以通过menuconfig在图形界面中去修改。

· 指定Kernel的配置文件

 BR2_LINUX_KERNEL_DEFCONFIG="nommu_hpmicro"

· 指定设备树文件

BR2_LINUX_KERNEL_DTS_SUPPORT=y
BR2_LINUX_KERNEL_INTREE_DTS_NAME="hpmicro/hpm6800-evk"

4.3 OpenSBI版本的指定

OpenSBI的版本指定和Kernel的版本指定类似

BR2_TARGET_OPENSBI_CUSTOM_REPO_URL="https://github.com/hpmicro/opensbi.git"
BR2_TARGET_OPENSBI_CUSTOM_REPO_VERSION="2900da09af75c80ed8c4a8553a35e94e0f3f5c0d"
BR2_TARGET_OPENSBI_VERSION="2900da09af75c80ed8c4a8553a35e94e0f3f5c0d"

· 指定OpenSBI的平台名称：

 BR2_TARGET_OPENSBI_PLAT="hpmicro"

4.4 镜像排布的指定

采用genimage对各个独立的镜像进行整合:创建genimage脚本文件genimage_opensbi.cfg, 指定每个镜像文件存放的位置:

flash w25q128 {
pebsize = 64K
numpebs = 256
minimum-io-unit-size = 1
}
image flash.img {
flash {
}
flashtype = "w25q128"
partition opensbiloader {
size = 64k
image = "opensbiloader.bin"
}
partition opensbi {
offset = 64K
image = "fw_jump.bin"
size = 192K
}

partition kernel {
image = "Image"
offset = 256K
size = 2880K
}
partition dtb {
image = "hpm6800-evk.dtb"
offset = 3136K
size = 64K
}
partition rootfs {
image = "rootfs.squashfs"
offset = 4M
size = 1M
}
}

5、编译过程

5.1 OpenSBI单独编译：

· Github仓库地址

https://github.com/hpmicro/opensbi.git

· 编译命令

 make all PLATFORM=hpmicro CROSS_COMPILE=riscv32-unknown-elf- HPMSOC=HPM6800 O={build_dir}

编译完成后可以在{build_dir}中找到platform/hpmicro/firmware/fw_jump.bin，需要loader将其拷贝到地址0然后再跳转到地址0来运行。

5.2 Loader参考：

· Github仓库地址

https://github.com/hpmicro/hpm_opensbi_loader.git

· 编译命令

 HPM_SDK_BASE={SDKBASE} GNURISCV_TOOLCHAIN_PATH={RISCV TOOLCHAIN PATH} HPM_SDK_TOOLCHAIN_VARIANT=gcc cmake -GNinja -DBOARD=hpm6800evk -DHPM_BUILD_TYPE=flash_xip -B build

5.3 buildroot工程编译：

· Github仓库地址

https://github.com/hpmicro/buildroot.git

· 编译命令

make hpmicro_hpm6800evk_defconfig
make all

6、烧录和运行

· 烧录需要用到hpm_manufacturing_tool，仓库地址：

https://github.com/hpmicro/hpm_manufacturing_tool.git

将buildroot生成的镜像output/images/flash.img重命名成flash.bin烧录到0x80000000即可。
