Hi,


This patch series rearranges and tidies various parts of kvmtool to pave the way
for the addition of support for another architecture -- SPAPR PPC64.  A second
patch series will follow to present the PPC64 support.

kvmtool is extremely x86-specific, so a fair chunk of refactoring into "common
code" vs "architecture-specific code" is performed in this set.  It also has a
(refreshingly small) set of endian bugs that are fixed, plus assumptions about
the hardware presented to the guest.

I've started the series with the main meat-- moving/renaming things like bios,
CPU setup, guest address space layout, interrupts, ioports etc., into a new x86/
directory.  The Makefile determines an architecture and builds the appropriate
dir, devices, etc.

Follow-on patches change some of the mechanics, for example modifying the loop
around ioctl(KVM_RUN) so that whilst it stays generic, it calls into
arch-specific code to handle specific exit reasons, MMIO etc.  The builtin-run
initialisation path is rationalised so that PCI & IRQs are initialised before
devices, and all of this happens before arch-specific code is given the chance
to initialise any firmware and generate any device trees.

Most of this series is fairly trivial, in moving code, making definitions
arch-local or available via a header, endian sanitisation.  The PCI code changes
are probably most 'interesting', in that I have made the config space accesses
available to those not using the PC ioport access method, plus wrapped
initialisations of config space with cpu_to_leXX accesses.

If there's anything in this series that'll cause the world to end, or stain, do
let me know. :)


Cheers,


Matt
