--enable-plugins:开启TCG Plugin支持 --disable-stack-protector:关闭QEMU自身的栈保护——我们仿真似乎不用担心被攻击的问题 --extra-cflags="-O3":能让你的QEMU提速5~10%,如果编译时报错,请加上--disable-werror 默认地,configure会编译所有ISA的QEMU,全量编译会耗时20分钟左右,其实很多时候我们不需要绝大多数...

QEMU基础10-QEMU user mode 和system mode不同,user mode不仿真指令集之外的所有,它仅提供Guest上Linux用户态程序的运行支持。 换言之,QEMU user mode是system mode的精简版,只提供TCG层面的支持,他能运行guest Linux上的用户态程序。 一、QEMU user mode可执行文件 QEMU为每一种ISA(Instruction Set Architecture)...
而buf_rw空间中TB对应的Host机器码的开头由TCGContext的code_buf指向,末端由TCGContext的code_ptr指向,两者之差则为机器码的长度。需要翻译第二个TB时,第二个TranslationBlock结构则会在TCGContext.code_ptr的后面再分配,TCGContext的code_buf和code_ptr则再指向第二个TB对...

这用于启用加速器。根据目标体系结构,可以使用kvm,xen,hax,hvf,whpx或tcg。默认情况下,使用tcg。如果指定了多个加速器,则如果前一个初始化失败,则使用下一个。 kernel_irqchip=on|off 如果可用,控制内核对irqchip的支持。 gfx_passthru=on|off 启用对选定计算机的IGD GFX直通支持(如果可用)。
Hi I want to write a TCG plugin to keep track what byte is load/store into memory. But the vcpu_mem stub seems only has the address, but not the value I store/load. How can I do that? static void vcpu_mem(unsigned int cpu_index, qemu_plugin_meminfo_t meminfo, uint64_t vaddr,...
