Re: [Xen-devel] Re: [Xen-ia64-devel] [PATCH][IA64] configure VHPT size p
Hi Yamahata-san,
I'm now thinking about PV domain. Please stay tuned.
As I mentioned before, vTLB is already minimum size(16KB)
and no collision for windows.
http://lists.xensource.com/archives/html/xen-ia64-devel/2007-08/msg00108.html
So I feel it's enough about vTLB. If smaller vTLB size is required,
we have to prepare a brand new hash function.
Thanks,
Kouya
