Re: [Qemu-devel] On x86 MMU modes

[Sandhya Kumar]

Thanks again. One more question.

On versions prior to the mentioned commit, is there any specific reason (in x86 source code of QEMU) to choose separate modes for address translations (of kernel and user mode)? Or was that done just for performance improvement?

Yes, they are specific to QEMU.

Real hardware TLBs probably work in a completely different (and
undocumented) way.
