首先由el0_sync根据异常发生的原因跳转到 el0_svc,然后由el0_svc 调用 el0_svc_handler、el0_svc_common 函数,将 X8 寄存器中存放的系统调用号传递给 invoke_syscall 函数。 随后执行invoke_syscall函数,将通用寄存器中的内容传入 syscall_fn(),引出系统调用内核处理函数 __arm64_sys_gettimeofday。系统调用内核...

然后用下面的命令运行qemu模拟器: qemu-system-arm -cpu cortex-m4 -machine netduinoplus2 -nographic -semihosting-config enable=on,target=native -kernel target/thumbv7m-none-eabi/debug/allocator-rs 出现了满屏的小点点.,模拟成功!
补丁,你可以到FC的cvs上去找,那个nptl的patch,用google搜索"qemu nptl patch arm"应该也能出来。 如果你的arm-linux-*工具链能编译静态版本的程序,那你可以试试写个简单C hello wolrd程序,编译为静态版本后,用刚才编译出来的静态qemu-arm跑一下试试。 好,现在,准备好你的arm版本的sysroot,把静态版本的qemu-ar...

[小技巧] Minicom和QEMU中触发magic sysrq minicom中触发magic sysrq键: 对于minicom,命令序列:“ctrl-a f”将启动一个中断序列。因此,命令:“ctrl-a f m”将显示有关系统内存的信息。 * What are the 'command' keys? ~~~ 'b' - Will immediately reboot the system...
