[Xen-ia64-devel] Recipe for getting/building/running Xen/ia64

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

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"


Getting and building the Xenlinux/ia64 "tip":
- create a directory to put it in:
        $ cd "HOME" # wherever you want to put it
        $ mkdir xenlinux-ia64-2.6.12.hg
        $ cd xenlinux-ia64-2.6.12.hg
- get the bits
        $ hg clone
http://xenbits.xensource.com/ext/xenlinux-ia64-2.6.12.hg
        $ hg update
- prep the xenlinux build
        $ cd "HOME"/xenlinux-ia64-2.6.12.hg
        $ cd include/asm-xen/
        $ ln -s asm-ia64 asm
        $ cd "HOME"/xenlinux-ia64-2.6.12.hg
        $ # following works for HP zx1-based systems
        $ cp arch/ia64/configs/xen_zx1defconfig .config
        $ # if you build your own .config, ensure that CONFIG_XEN=y
        $ # and there are no modules (replace all "=m" with "=y")
- build xenlinux
        $ cd "HOME"/xenlinux-ia64-2.6.12.hg
        $ yes "" | make oldconfig
        $ make
        $ # resulting xenlinux binary is called vmlinux

- prep the bootloader
        $ # where is your elilo.conf file?  call this "BOOTDIR"
        $ # add an entry to "BOOTDIR"/elilo.conf
        $ # the exact syntax for the "append=" is very system
dependent...
        $ # the part before the '--' is for xen... 
        $ # the part after the '--' should look like your normal linux
bootline
        $ # FIXME: not sure if nomca is still needed
                image=xen
                label=xen
                initrd=xenlinux
                read-only
                read-only
                append="sched=bvt -- nomca console=ttyS0,115200
root=/dev/sda2"
                
Booting Xen/ia64:
        $ cd "HOME"/xen-ia64-unstable.hg
        $ cp xen "BOOTDIR"
        $ cd "HOME"/xenlinux-ia64-2.6.12.hg
        $ cp vmlinux "BOOTDIR"/xenlinux
        $ # if you see no output on your console, you may need to
specify
        $ # a com1= on the Xen part of the "append=" line.  Note that
the
        $ # syntax for this is different than for linux.  FIXME: docs
        $ # for this will be documented in a separate file
