如何在WSL 2中读取物理内存？

#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <sys/mman.h>
#include <fcntl.h>
#include <unistd.h>

#define PHYSICAL_MEMORY_PATH "/dev/mem"

int main() {
    int fd = open(PHYSICAL_MEMORY_PATH, O_RDWR);
    if (fd == -1) {
        perror("Failed to open /dev/mem");
        return 1;
    }

    // 读取物理地址0x1000处的内容
    off_t offset = 0x1000;
    size_t length = 4; // 读取4字节
    uint32_t *ptr = mmap(NULL, length, PROT_READ | PROT_WRITE, MAP_SHARED, fd, offset);

    if (ptr == MAP_FAILED) {
        perror("Failed to mmap");
        close(fd);
        return 1;
    }

    printf("Memory at 0x%lx: 0x%x\n", offset, *ptr);

    munmap(ptr, length);
    close(fd);
    return 0;
}

sudo gcc -o read_physical_memory read_physical_memory.c
sudo ./read_physical_memory
