Hello everyone,
this is the very first version of the patch series that introduces ARMv7
with virtualization extensions support in Xen.
The series allows Xen and Dom0 to boot on a Cortex-A15 based Versatile
Express simulator.
See the following announce email for more informations about what we
are trying to achieve, as well as the original git history:
See http://marc.info/?l=xen-devel&m=132257857628098&w=2
The first 7 patches affect generic Xen code and are not ARM specific;
often they fix real issues, hidden in the default X86 configuration.
The following 18 patches introduce ARMv7 with virtualization extensions
support: makefiles first, then the asm-arm header files and finally
everything else, ordered in a way that should make the patches easier
to read.
Although I have been working on cleaning these patches for a week now,
this is just the first version of the series, so expect some rough
edges. You have been warned :-)
Also keep in mind that many functions still have only a dummy
implementation; we hope to fill the gaps as soon as possible.
Please read the patch series and let me know if you find any bugs, have
any comments or suggestions. With your help I am looking forward to
improving the quality of this work.
