bigdot 说:

希望这个模拟器能够加载 UART、SPI、Ethernet、usb等自定义外设,采用plugin模式,类似device tree。另外,建议提供demo,然后就能实用化了。

谢谢大佬的建议,会把这些建议加入到TODO list.

1. clone this project

git clone https://gitee.com/xunxiaohuii/juice_lc-3

or

git clone https://github.com/xiaoxiaohuixxh/juice_lc-3

2. download and compile verilator simulator
2.1 download verilator source code , install the tools of dependence for compile verilator

# Prerequisites:
sudo apt-get install git perl python3 make autoconf g++ flex bison ccache
sudo apt-get install libgoogle-perftools-dev numactl perl-doc
sudo apt-get install libfl2  # Ubuntu only (ignore if gives error)
sudo apt-get install libfl-dev  # Ubuntu only (ignore if gives error)
sudo apt-get install zlibc zlib1g zlib1g-dev  # Ubuntu only (ignore if gives error)

cd juice_lc-3/juicelc3/tools

git clone https://github.com/verilator/verilator   # Only first time
cd verilator
git pull         # Make sure git repository is up-to-date
git tag          # See what versions exist
git checkout aa86c777f4787db7d10fbbbb5019ed4d20a7fcfb  # switch to v4.220 version

2.2 compile the verilator source code

unset VERILATOR_ROOT  # For bash
autoconf         # Create ./configure script
./configure      # Configure and create Makefile
make -j `nproc`  # Build Verilator itself (if error, try just 'make')
./bin/verilator --version

the version for my verilator is

Verilator 4.221 devel rev v4.220-35-g2b91d764

3. design compile juicelc3 soc demo

pwd

is xxx/juice_lc-3/juicelc3/tools/verilator
switch to juicelc3 soc demo directory

cd ../../sim/verilator/jlc3_soc
chmod +x ../../../tools/LC-3_Assembler/nglc3asm

run design compile

make run # will be automaticlly run dc,compile asm code and run demo
➜  jlc3_soc git:(master) ✗ make run

xiaotianhu 说:

大佬,什么时候会开源啊。非常好奇想学习一下的说

他的外设和组件已经在逐步开源了呢。

gdb组件开源:
https://github.com/juiceRv/gdb_stub_for_juicevm


fb组件开源:
https://github.com/juiceRv/tinygl_sdl_test

暂时不开源虚拟机的cpu部分。
cpu部分以为耦合性比较强,正在拆分成多级流水线的实现方式,使用内置的调度器进行并行处理。所以暂时没有开源时间公布。

#22 Re: RISC-V » [juicevm] 只需要不到5000行代码实现一个risc-v虚拟机,纯c语言实现,无第三方库,支持ESP32 & GDB » 2021-09-02 19:53:28

20210902更新:
可能有小伙伴以为juicevm不更新了,打算做成TLS的,这次更新时间长是因为我把代码框架重构了,为后面的多核和多架构支持做好了准备。
这次更新除了框架重构外还添加了risc-v32 ima的支持(在rv32下暂不支持任何MMU,但是已经在TODO里啦,只要是RV32支持的将全都有),还即将支持用设备树来实现动态的寄存器地址和外设配置呢。下面我们下载下最新的支持体验下吧!!!
这次上传只打包了linux下的版本,window和macos的在路上了。

shaoxi2010 说:

大神,这个能在macOS下编译一个么,试了下NEMU但是无法编译出可以在用户态下运行的程序

juicevm 新增了macos的发行包了,后面上传上来。
这里的用户态是指risc-v里的user mode还是macos的用户程序?
如果是risc-v 的用户模式是支持的,用户程序的话不支持呢。

这里是在解压,压缩率有点高,解压有点慢。

讨论帖:
需要给juicevm添加一个显示器外设,想来坑网投个票:请在讨论里回复自己的想法,谢谢大家的支持
1.类似大多数soc里的做法,实现一个lcd控制器。
2.实现类似vga控制器的做法,控制当前笔的位置和颜色。

分享下软件的参数说明:
t: enable test mode
进入固件测试模式
当出现下面的状态会结束运行并且打印出通过还是失败的字样
x3_gp寄存器的值为1 和 x17_a7寄存器的值为93时,进入了ecall异常就会触发。x10_a0 寄存器的值为 0时打印pass字样,否则打印fail字样
-------------------------------------------------------------------------------
T: enable trap debug mode
使能异常调试模式,出现异常时会打印当前异常的调试信息
-------------------------------------------------------------------------------
d: enable debug mode
打开虚拟机内所有的调试选项,输出最详细的调试信息,包括指令译码,处理执行,当前寄存器列表,csr列表等
-------------------------------------------------------------------------------
c: print cst operation msg
打开虚拟机的csr寄存器读写调试信息。读写csr寄存器的时候都会打印对应的csr寄存器的值
-------------------------------------------------------------------------------
a: diable all debug msg
关闭所有调试选项,译码调试默认打开
-------------------------------------------------------------------------------
x: enable test mode for exception
打开异常测试模式,当出现异常时结束运行
-------------------------------------------------------------------------------
g: enable better readability printing
使用可读性更好的方式打印信息
-------------------------------------------------------------------------------
e: disable all error msg
关闭所有的错误信息打印
-------------------------------------------------------------------------------
i: enable all instr debug msg
打开所有指令调试信息打印
-------------------------------------------------------------------------------
m: enable mmu debug msg
打开mmu的遍历调试信息
-------------------------------------------------------------------------------
p: print mmu page 8 byte data
hexdump打印mmu页表里的8字节数据
-------------------------------------------------------------------------------
P: print mmu page 4K Byte data
hexdump打印mmu页表里的4K字节数据
-------------------------------------------------------------------------------
s: uart addr not use mmu translation
启用mmu翻译时,忽略uart的外设地址,在启用了mmu的时候也可以直接通过uart原始物理地址来操作uart外设
-------------------------------------------------------------------------------
S: switch mode debug info
打开切换mode时的调试信息,m-mode,s-mode和u-mode切换的时候都会打印调试信息
-------------------------------------------------------------------------------
M: disable mmu err msg
关闭mmu缺页异常,访问异常,加载异常的错误信息
-------------------------------------------------------------------------------
r: enable trap debug msg
打印更详细的进入中断的调试信息
-------------------------------------------------------------------------------
A: enable addr translation debug print
打印地址转换的调试打印
-------------------------------------------------------------------------------
L(n): output_mode_sel n = 0 -> stdout
                          1 -> log_buf UNIX SYS ONLY(buf_size:(2900))
                          2 -> none
选择虚拟机输出的方式,1,直接标准输出。2,使用一个buf先缓存,退出的时候再输出bug大小2900Byte。3,不输出。
-------------------------------------------------------------------------------
l: enable endless loop check (RV_ENDLESS_LOOP_CHECK_EXIT_CNT:(3))
启用死循环监测机制,当有连续3次出现同样的指令执行流程(包括寄存器和csr寄存器的值都没有改变),结束虚拟机的运行。可以搭配-L参数使用,方便调试固件。一般assert都是直接死循环。
-------------------------------------------------------------------------------

opensbi和kernel的代码已发布到github!!!
https://github.com/juiceRv/kernel_juicevm_port
kernel的配置文件在arch/riscv/configs/juicevm_defconfig,make ARCH=riscv juicevm_defconfig
需要修改下arch/riscv/configs/juicevm_defconfig里的CONFIG_INITRAMFS_SOURCE="/mnt/ssd_prj/risc-v_sim/sim/test/opensbi/opensbi-master/rootfs"
修改为opensbi里的路径

然后,使用esp的方式直接编译即可。

如果编译过程总,提供btstack文件找不到的话,做如下修改:
1. main/CMakeLists.txt中,去掉btstack的.c,以及去掉btstack_demo.c
2. source/example/template/config/vsf_usr_cfg/vsf_usr_cfg_esp32s2.h里,APP_USE_BTSTACK_DEMO配置为DISABLED

esp32的windows环境下,遇到一些问题,就是如果参与编译的文件太多,连接会出错,官方没有提供任何解决方案。
linux环境下没问题。
解决方法,去掉一些模块,修改source/vsf/component/CMakeLists.txt,去掉3rd-parth、crypto、debugger、tcpip、ui。当然,实际可能不需要去掉这么多

支持,难见的好项目

关于risc-v的mtime的简单描述
在risc-v里mtime是作为外设存在的,他的寄存器地址不在risc-v的规范范围内,是有soc设计厂商自己定义的。mtime包括了两个寄存器mtimemtimecmp。这两个寄存器的长度在官方的规范里规定是64bit(无论xlen是多少

mtime的中断使能在csrji寄存器mie(machine interrupt enable)里指定。

mtime中断发生时,ecode为7(特权文档版本:1.12-draft里描述到),flag为1.
下面引用原文。
The mtime register has a 64-bit precision on all RV32 and RV64
systems. Platforms provide a 64- bit memory-mapped machine-mode timer
compare register (mtimecmp). A timer interrupt becomes 34 Volume II:
RISC-V Privileged Architectures V1.12-draft pending whenever mtime
contains a value greater than or equal to mtimecmp, treating the
values as unsigned integers. The interrupt remains posted until
mtimecmp becomes greater than mtime (typically as a result of writing
mtimecmp). The interrupt will only be taken if interrupts are enabled
and the MTIE bit is set in the mie register.

mtime寄存器里的值 大于等于 mtimecmp寄存器的值时(比较时使用无符号的大小比较方式),需要触发mtime中断。

而且中断会一直触发直到mtimecmp寄存器的值 大于 mtime寄存器里的值 。

下一篇文章会描述freertos里对于risc-v的mtime相关的适配。

为什么不叫移植freertos-kernel呢?因为从下面freertos-kernel的发布历史可以看到,freertos内核从FreeRTOS V10.1.1 and FreeRTOS V10.2.0开始就支持risc-v了,但是这个版本对于64bit的risc-v的支持好像还有点小问题。一直到FreeRTOS V10.2.1 and FreeRTOS V10.2.0 的发布支持了32位和64位的risc-v。如果要使用建议从这个版本开始进行适配工作。

 Changes between FreeRTOS V10.2.1 and FreeRTOS V10.2.0 released May 13
 2019:
 
     + Added ARM Cortex-M23 port layer to complement the pre-existing ARM
       Cortex-M33 port layer.     + The RISC-V port now automatically
 switches between 32-bit and 64-bit       cores.

 February 25 2019:
  
   + Added GCC RISC-V MCU port with three separate demo applications. 
   ...    

## 做下准备
下面我们整理下适配一个比较规范的risc-v内核需要进行哪些工作和需要risc-v内核支持哪些外设才可以让freertos-kernel正常运行.

我们都知道,最简单的rtos运行只需要一个时钟为他提供一个基准时钟用于任务时间分片的计算,触发上下文切换和任务间通信的超时等操作。在freertos里还需要一片空间用户存放任务的栈。
在freertos适配risc-v的时候我们通常还会使用risc-v里的机器时钟mtime,他是一个只有计时用途的简易计数器,可以为freertos提供一个基准时钟。也可以使用一个硬件定时器代替。
freertos默认还会使用ecall指令,用于出让cpu控制权。通过修改也可以使用其他指令(如果是自己设计的核,你用着开心就好)。
## 应该准备好了,开始
好了,到现在我们已经准备好了freertos需要的运行条件。

1. 设置栈顶
    我们需要指定

__freertos_irq_stack_top

这个符号,告诉freertos任务的栈需要存放到哪里。
2. 设置mtime寄存器信息
     在FreeRTOSConfig.h文件里设置mtime寄存器信息
   

	#define configMTIME_BASE_ADDRESS 	( pdev_mtime_mtime_addr )
	#define configMTIMECMP_BASE_ADDRESS( pdev_mtime_mtimecmp_addr )
	

3. 确认HOOK配置

   

	#define configUSE_IDLE_HOOK				0
	#define configUSE_TICK_HOOK				1
	

4. 设置cpu频率和Tick中断的频率

   

	#define configCPU_CLOCK_HZ				( 1000 )
	#define configTICK_RATE_HZ				( ( TickType_t ) 1 )
	

5. 设置最小栈大小限制和堆的总大小

   

	#define configMINIMAL_STACK_SIZE		( ( unsigned short ) 105 )
	#define configTOTAL_HEAP_SIZE			( ( size_t ) 14500 )
	

6. 设置任务名称最大的长度(如无特殊,保持默认即可)

   

	#define configMAX_TASK_NAME_LEN			( 16 )
	

7. 通过宏定义 __riscv_xlen 指定指令长度
    如果是64bit的risc-v平台可以参考下面编译参数
   

	CFLAGS      += -D__riscv_xlen=64 -D__riscv64
	

    如果是32bit的risc-v平台可以参考下面编译参数
   

	CFLAGS      += -D__riscv_xlen=32
	

   

8. 第7点声明的__riscv64宏定义主要作用

   

	#ifdef __riscv64
		#define portBYTE_ALIGNMENT			8
	#else
		#define portBYTE_ALIGNMENT			16
	#endif
	

    从上面的代码可以看出主要是用于设置字节对齐大小

到这里freertos的基本设置已经完成!!下面需要编写平台初始化的代码,然后初始化freertos,创建任务,调用调度函数即可。

# 平台初始化
下面附上简单的平台初始化代码
start.S

    #include "rv_mtvec_map.h"
    .macro init;
    .endm
    .section .init;
    .option norvc
    .option nopic
    .align  6;
    .weak reset_vector;
    .globl _start;
    .type _start,@function
    
_start:
    la sp, __stack_end                                    
    /* reset vector */
    addi s2, x0, 'a';
    li  t1, pdev_uart0_write_addr;
    sb s2,0(t1);

    addi s2, x0, 'b';
    li  t1, pdev_uart0_write_addr;
    sb s2,0(t1);

    addi s2, x0, '\n';
    li  t1, pdev_uart0_write_addr;
    sb s2,0(t1);
    
    j reset_vector
    .align  4;                                             
reset_vector:
    addi s2, x0, 'r';
    li  t1, pdev_uart0_write_addr;
    sb s2,0(t1);

    addi s2, x0, '\n';
    li  t1, pdev_uart0_write_addr;
    sb s2,0(t1);
    
    la a0,e_vertor;

2:
	/* Clear bss section */
	la a0, __bss_start;
	la a1, __bss_end;
	bgeu a0, a1, 2f;
1:
	# sw zero, (a0);
	addi a0, a0, 4;
	bltu a0, a1, 1b;
2:

    call main;
    unimp

main.c

void main(void){
    // *(uint64_t *)(pdev_mtime_mtimecmp_addr+1) = 300;
    uint64_t i;
    puts("main\n");
    extern void main_blinky( void );
    main_blinky();
    puts("main_blinky\n");
    while(1){
        i = 1000;
        while(i--);
        puts("wait for cb\n");
    }
}

freertos的适配到此为止,感谢观看!!发现有疑问或者错误的地方欢迎发邮件到juicemail@163.com联系作者,谢谢!!期待您的参与!!!

换成字符串来表示了,使用cjson请不要使用64bit的变量了,防止出现和楼主一样的情况出现。cjson的issue可以看到2018年的时候已经有人提出过这个疑问,但是官方认为64bit很少使用所以被否决了提议。所以cjson在2020-11-30年还是不支持64bit的。

if not str or str == "" then return end 这是如果这个变量不存在或者为nil或者为空字符就退出。
if str ~= true then这里是str不为true,因为lua是弱类型脚本语言,write(uid, false)就是不为true了哦。write(uid, 1)就是不为true了哦。

更新beta0.3.1
更新日志:
1,测试raw repl mode,注意此模式无回显而且输入命令后按ctrl+d执行。
2,移植了freertos仅供测试,还没对接到micropython的api,just for funny。
欢迎使用测试脚本:
import utime
while 1:
    print("delay 1s")
    utime.sleep_ms(1000)
