[Xen-devel][PATCH][VTD]Utilise the snoop control capability in shadow with VT-d code
The patch attached utilise the snoop control capability in shadow with VT-d code. We compute the shadow PAT index in leaf page entries now as: 1) No VT-d assigned: let shadow PAT index as WB, handled already in shadow code before. 2) direct assigned MMIO area: let shadow code compute the shadow PAT with gMTRR=UC and gPAT value. 3) Snoop control enable: let shadow PAT index as WB. 4) Snoop control disable: let shadow code compute the shadow PAT with gMTRR and gPAT, handled already in shadow code before Signed-off-by: Xin, Xiaohui <xiaohui.xin@intel.com> _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
