> > The set of patches split x86 architecture specific operations from DPDK and put
> > them to x86 arch directory.
> > This will make the adoption of DPDK much easier on other computer architecture.
> > For a new architecture, just add an architecture specific directory and
> > necessary building configuration files, then DPDK eal library can support it.
> > Reviewing patchset from Chao, I ended up modifying it along the way,
> > so here is a new iteration of this patchset.
> > Changes since Chao v2 patchset :
> > - added a preliminary patch for moving rte_atomic.h (for better readability)
> > - fixed documentation generation
> > - implemented a generic header for each arch specific header (cpuflags, memcpy,
> > prefetch were missing)
> > - removed C++ stuff from generic headers
> > - centralised all doxygen stuff in generic headers (no need to have duplicates)
> > - refactored rte_cycles functions
> > - moved vmware tsc stuff to arch rte_cycles.h headers
> > - finished x86 factorisation
> > Little summary of current state :
> > - all applications continue to include the eal headers as before, these headers
> > are the arch-specific ones
> > - the arch specific headers always include the generic ones. The generic headers
> > contain the doxygen documentation and code common to all architectures
> > - a x86 architecture has been defined which handles both 32bits and 64bits
> > peculiarities
> > It builds fine for 32/64 bits (w and w/o "force intrinsics"), but I really would
> > like a lot of eyes on this (and I would say, especially, rte_cycles, rte_memcpy
> > and rte_cpuflags).
> > I still have some concerns about the use of intrinsics for architecture != x86
> > but I think Chao will be the best to look at this.

Thanks for the big clean-up.
Now we are ready to accept new CPUs.
