[Xen-ia64-devel] Shortage of Xen heap problem

[Masaki Kanno <kanno.masaki@xxxxxxxxxxxxxx>]

Hi,

When Xen SMP is supported, it becomes Xen heap shortage with 3 CPUs or more.
Because Xen heap is required 16MB per CPU for VHPT. 
(Refer to attached file Xenheapshortage.txt)

I think that I will expand the size of Xen heap according to the value of 
NR_CPUS. 
I have the idea as follows.

#ifdef CONFIG_SMP
  Xen heap size = 63MB(default) + 16MB * NR_CPUS;
#else
  Xen heap size = 63MB(default);
#endif

Any idea and comment?

Best Regards,
 Kan
