CPU从内存中读取指令进行译码并执行,执行的过程中需要去访问内存中的数据,CPU内部的寄存器可以暂存中间的指令和数据等信息,通常说的CPU的context指的就是CPU寄存器值; 在硬件支持虚拟化之前,Qemu纯软件虚拟化方案,是通过tcg(tiny code generator)的方式来进行指令翻译,翻译成Host处理器架构的指令来执行。硬件虚拟化技术...
在QEMU中,翻译器每翻译一个块都会把翻译后可以在目标机上执行的代码存放到Code cache中,但是由于自修代码的出现使得在Code cache中的块与源代码块在语义上不一致,因此必须清除掉Code cache中的翻译好的块,否则将执行与原来语义不一致的代码,造成翻译的错误。QEMU在自修改代码发生时对Code cache采用全清空策略[6],...
