RE: [Xen-ia64-devel] RE: [elilo-discuss] a patch to make elilo loadanother module

["Xu, Anthony" <anthony.xu@xxxxxxxxx>]

Brett,

Please pull the attached elilo patch which is to add support for extra
module load for Xen in ia64 environment.
The following elilo.conf entry highlighted the new added support

image=xen.gz          <=== Xen image to be loaded by elilo
        label=xen
        initrd=initrd-2.6.12.EL 
        module=vmlinuz-2.6.12.EL.img   <=== Linux kernel to be run in
Domain0 Linux in Xen
        read-only
        append="console=tty0 root=/dev/sda2"

The attached patch has been validated to work in Linux2.6 environment.

Regards,

Anthony Xu
Intel Corp.

Hi Brett --

I haven't studied the details, but implemented a similar
patch on top of elilo for a previous HP research project
a couple years ago...  mine was really a hack though and
I'm sure you want this one to be more generally useful.

If the patch:
1) allows at least one additional "initrd-like" file to be
   specified, and
2) elilo loads the additional file(s) into physical
   memory, and
3) elilo somehow communicates the location of the additional
   file via some kind of backwards-compatible extension to
   ia64_boot_param, and
4) the patch gets into the mainline elilo source asap

then the patch meets my needs (which I believe are the same
as Anthony's).

I've also cc'ed the xen-ia64-devel list so other Xen/ia64
folks can chime in.

Dan
