我正在尝试在qemu中运行交叉编译的内核。 我正在模拟integratorcp板上的ARM9系列处理器。 这是在qemu-system-arm下支持的，并且这个设置存在于上面的命令行中。 尽管我使用scratchbox提供的交叉构建工具链，但我并没有在scratchbox中进行编译。 这是因为交叉支持对于内核来说相当完善，实际上建议不要在scratchbox中完成。 一切都编译到这个内核中。 尽管可加载模块支持已启用，但未构建模块。 我能够成功生成压缩二进制文件（zImage）。 当qemu-system-arm将它作为内核插入时，它成功解压缩Linux并几乎立即挂起。 将未压缩的内核二进制文件（/usr/src/linux-2.8.16-source/vmlinux）提供给arm-uclibc-gdb以进行符号提取似乎也可以。 设置断点并逐步完成说明似乎是准确的。 我能够使用arm-uclibc-gdb来捕获违规行。 在vgacon_startup（void）函数内的drivers / video / console / vgacon.c：462中发生崩溃。 在尝试进入462行的inb_p（VGA_IS1_RC）指令后，它会蜷缩床。 在__do_kernel_fault处设置断点，callstack如下所示：`
#0 __do_kernel_fault (mm=0xc0225f28, addr=53, fsr=53, regs=0x30001)

...
#15000 0xc0023848 in __dabt_svc () at proc_fs.h:194
...
我最终放弃了试图找到正在调用__dabt_svc
几个兴趣点：
inb_p ，似乎也不可能检查某些变量/函数并设置中断。 inb_p ，man文档明确指出，您需要使用-O或-O2进行编译; 否则，可能会导致子程序未被内联 __show_regs()并手动窥探所有相关的寄存器（pc，fsr等）。 这听起来并不难。 它听起来很乏味。 我会非常感激一双新鲜的眼睛，或者至少在正确的方向点头。 预先感谢您阅读了这篇文章，并提供任何帮助。
看来，QEMU不会在其ARM集成器仿真中模拟VGA设备。

什么是内核命令行？ 您首先使用下面的一行将控制台放在串行端口上：
console=/dev/ttyS0或console=/dev/ttyAMA0
然后消息应该开始流动。 如果你的内核过早死机，你也可以尝试下面的黑客行为：
