RE: Réf. : [Xen-ia64-devel] Recipe for getting/building/running Xen/ia64

The current code should work on a multiprocessor system but
will utilize only one of the processors.  SMP support will
be next on the list after getting multiple domains working
well.

        Dan, 
        can the current ia64 code run on a (physical) multiprocessor system ?

Xen/ia64 
        
        A lot has changed in Xen/ia64 since the README files in
        arch/ia64/tools were written.  Attached is the first draft
        of a recipe for getting/building/running Xen/ia64.
        It will need some work, but if you are a Xen/ia64 "newbie"
        and have been eager to give Xen/ia64 a try, please try
        following this recipe and provide changes/feedback.
        It will eventually find its way back into a README file.
        
        Thanks,
        Dan
        
        =======
        
        Preparation:  On your ia64 system, you will need:
        - python2.3, see http://www.python.org
        - the mercurial (aka "hg") open-source source code management software
         version >= 0.6b, see: http://www.selenic.com/mercurial/ 
        - gcc version >= 3.2 (4.0 is not known to work yet though)
        - a copy of linux 2.6.11 (tar file)
        
        Getting and building the Xen/ia64 "tip":
        - create a directory to put it in:
                        $ cd "HOME" # wherever you want to put it
                        $ mkdir xen-ia64-unstable.hg
                        $ cd xen-ia64-unstable.hg
        - get the bits
                        $ hg clone 
http://xenbits.xensource.com/ext/xen-ia64-unstable.hg
                        $ hg update
        - unpack linux (many linux files are directly used by xen/ia64)
                        $ cd "HOME"
                        $ cp ..../linux-2.6.11.tar.gz .
                        $ tar xzf linux-2.6.11.tar.gz
        - build Xen/ia64
                        $ cd "HOME"/xen-ia64-unstable.hg
                        $ cd xen
                        $ bash arch/ia64/tools/mkbuildtree
                        $ make # if using the cross-compiler, use "make
        XEN_TARGET_ARCH=ia64"
