Re: [Xen-ia64-devel] [PATCH] Allow multiple-time mmap of the privcmddevice

[Isaku Yamahata <yamahata@xxxxxxxxxxxxx>]

Thank you for the log.
The oom-killer of dom0 was triggered. Alex also reporeted it.
Please increase dom0 memory and decrease vti domain memory
as a work around for now. 
When I tested, I used 512MB(default) for dom0 and 128MB for vti domU.

The root cause is the current implementation of foregin domain
page mapping wastes dom0 memory to allocate pseudo physical address.
(xen_ia64_privcmd_entry_mmap() in
 linux-2.6-xen-sparse/arch/ia64/xen/hypervisor.c)
I will fix this waste of dom0 memory by foreign domain page mapping.
