AArch64 has them. I had thought that you'd be able to treat one 128-bit reg as two 64 bit regs (in the same way that in 32-bit ARM the 64 bit register d0 is accessible as the pair of 32 bit regs s0,s1). However AArch64 doesn't overlap its registers in the same way, so userspace will need to access them as 128 bit registers to get the full state. -- PMM -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
