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.

Subject	[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?_______________________________________________
