ARM设备上的kvm基于ARM虚拟化支持,即需要ARM EL2权限(ARMv8以上架构的SOC)或HYP权限(ARMv7)。在X86设备上就好比,必须在BIOS中启用VT-X或AMD-V才能开启KVM加速。但是问题是,就算我们解开了BL锁,那么我的高通手机也是运行在EL1模式,这个EL2模式不对普通用户所开放的,除非你用的是高通SOC原型机或者高通开发板,...
那么在armv8.0之前呢,如armv7是怎样实现的?如下所示, 这段代码中最核心的也就是ldrex、strex指令了。 (linux/arch/arm/include/asm/atomic.h) static inline void atomic_##op(int i, atomic_t *v) \ { \ unsigned long tmp; int result; \ \ prefetchw(&v->counter); \ __asm__ __volatile__...

Goldfish处理器有两个版本,分别是ARMv5和ARMv7,在一般情况下,只需使用ARMv5版本即可。在Android开源工程的代码仓库中,使用git工具得到Goldfish内核代码的命令如下所示: $git clone git://android.git.kernel.org/kernel/common.git在其Linux源代码的根目录中,配置和编译Goldfish内核的过程如下所示:$makeARCH=arm gol...
