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

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

Very good suggestion, I can do this,
What I concern is where xen can put dom0 initrd.img in dom0 physical address 
space?
In native environment, the initrd.img loading address is determined by elilo 
memory allocate function.
How can xen determine this address? In theory, xen should not manage dom0 
physical address space.
any suggestion?

Nice.  I'll give the recipe a try next week.

Should this kind of computation be in a macro
and/or commented?

        module_size-0x1000-4*1024*1024)&(~0xfffUL)
