Re: [XenPPC] 128 meg domU???


(Just for logging the forgotten part here)

xen_init_early() in <test/lib/xenlib/xen_routines.c> hard-codes the address of xen_start_info as 64MB-16KB, so this should also be modified for 128MB.
From chat with Orran, he already modified it, but 128MB domU still didn't work.

[XenPPC] 128 meg domU???






Been trying to increase the memory used for our library OS to 128Meg,


In ppc970.c switched the rma size to 128 meg:

 

unsigned int cpu_default_rma_order_pages(void)

{

-    return rma_orders[0].order - PAGE_SHIFT;

+    return rma_orders[1].order - PAGE_SHIFT;

}


Also, modified the configuraiton

# Initial memory allocation (in megabytes) for the new domain.

memory = 128


I got a series of hypervisor calls, but console output no longer worked.  My assumption was that start_info was moved, but as far as I can tell the memory location is hardcoded in the domain builder.
Got from amos a linux, and modified its configuraiton the same way.  It hit a bug in Xen:


(XEN) BUG at mm.c:383


I also changed xen to have an rma of 64Meg (i.e., undid the change above) and changed just the configuraiton file, and got the same BUG at mm.c:383


is there anything else needed to support 128 meg domu?
