[Xen-devel][PATCH] Enable VPID (Virtual Processor Identification)
The vpid.patch attached enables the VPID feature. When present, it allows TLB entries to be retained across VM entry and VM exit, and Xen can now identify distinct address spaces through a new virtual-processor ID (VPID) field of the VMCS. The patch should be applied after ept.patch. arch/x86/hvm/vmx/vmcs.c | 17 ++++++++ arch/x86/hvm/vmx/vmx.c | 82 +++++++++++++++++++++++++++++++++++++++-- include/asm-x86/hvm/domain.h | 1 include/asm-x86/hvm/vmx/vmcs.h | 8 ++++ include/asm-x86/hvm/vmx/vmx.h | 34 +++++++++++++++++ 5 files changed, 138 insertions(+), 4 deletions(-) Signed-off-by: Xin Li xin.b.li@intel.com Signed-off-by: Jun Nakajima jun.nakajima@intel.com Signed-off-by: Xiaohui Xin <Xiaohui.xin@intel.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
