Adding New CPU Architecture to QEMU - Marek Vašut, DENX Software Engineering

Feedback form is now closed.
This talk provides an overview of the internals of the QEMU system emulator. After a brief introduction of QEMU itself, Marek will explain what pieces need to be filled in to add a new architecture to QEMU. The first topic is TCG, and how it is used to emulate the foreign instruction set on a host system with minimum performance penalty. Since emulating instructions properly has various pitfalls, Marek will point those out in the implementation of the Intel NiosII CPU instruction set for QEMU, which is tiny yet already capable of running Linux. Still, emulating instruction set does not make a usable emulation, thus the second part of the talk will focus on implementing models of real hardware in the context of QEMU. Finally, Marek will explain how to add support for emulating Linux userspace binaries.
