Any advice about the patch cr8-acceleration-3.patch? Hi Keir, could you give some comments? Thanks! -- Dexuan -----Original Message----- From: xen-devel-bounces@xxxxxxxxxxxxxxxxxxx [mailto:xen-devel-bounces@xxxxxxxxxxxxxxxxxxx] On Behalf Of Cui, Dexuan Sent: 2006年10月25日 11:12 To: Keir.Fraser@xxxxxxxxxxxx Cc: xen-devel@xxxxxxxxxxxxxxxxxxx Subject: [Xen-devel] [Patch][RESEND] Add hardware CR8 acceleration for TPRaccessing x64 Windows uses CR8 to access TPR very frequently. This patch enables TPR shadow and allows mov-from/to-CR8 to access it directly; tests indicates it can boost greatly the performance of x64 Windows 2003.
