[Xen-ia64-devel] [PATCH][IA64] configure VHPT size per HVM domain

2007-10-16 Thread Kouya Shimura
Hi Keir and Alex, A Virtual Hash Page Table(VHPT) is a special feature of IA64. It's an extension of TLB that resides in memory and can be automatically searched by the processor. This patch allows user to configure VHPT size per HVM domain. We have an interesting result. We tried some large

Hi Kouya. I guess Linux PV domains (especially dom0) possibly can gain similar performance improvement by increasing VHPT size too. So would it be easy to make vhpt parameter non hvm specific? I know your concern is hvm domain, though. On Tue, Oct 16, 2007 at 03:21:39PM +0900, Kouya Shimura

I've cleaned up the xc.hvm_build() interface in changeset 16116. Please merge against that. The main change will be that you will set the new HVM parameter in IA64_HVM_ImageHandler.buildDomain(), rather than passing the new parameter down to xc.hvm_build(). -- Keir On 16/10/07 07:21, Kouya

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
