Since we\nanticipate requiring a third walk (for invlpg), it makes sense to have\na generic facility for shadow walk.\n\nThis patch adds such a shadow walker, walks the page tables and calls a\nmethod for every spte encountered. The method can examine the spte,\nmodify it, or even instantiate it. The walk can be aborted by returning\nnonzero from the method.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "6c41f428b72afe5a581b967590c12538db31d399", "tree": "8b1cd1520469b23d033d7046db2d03ef727d54a4", "parents": [ "0be9e929e398d6da6406183a8732dbfd0937fafe" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Tue Aug 26 16:16:08 2008 +0300" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Wed Oct 15 10:15:22 2008 +0200" }, "message": "KVM: MMU: Infer shadow root level in direct_map()\n\nIn all cases the shadow root level is available in mmu.shadow_root_level,\nso there is no need to pass it as a parameter.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "0be9e929e398d6da6406183a8732dbfd0937fafe", "tree": "7556b5d3bf220d5536b1089f71e7578a1bfa205b", "parents": [ "6e37d3dc3e358dbf907f8b96a51282966934124b" ], "author": { "name": "Xiantao Zhang", "email": "xiantao.zhang@intel.com", "time": "Tue Aug 26 08:58:53 2008 +0800" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Wed Oct 15 10:15:22 2008 +0200" }, "message": "KVM: ia64: Enable virtio driver for ia64 in Kconfig\n\nkvm/ia64 uses the virtio drivers to optimize its I/O subsytem.\n\nSigned-off-by: Xiantao Zhang \u003cxiantao.zhang@intel.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "6e37d3dc3e358dbf907f8b96a51282966934124b", "tree": "9a759cc77d4ca952b4c2aca2f10d8b4239f682a3", "parents": [ "135f8c2b078533cc74e75f696e73d47304a61125" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Fri Aug 22 19:14:17 2008 +0300" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Wed Oct 15 10:15:22 2008 +0200" }, "message": "KVM: MMU: Unify direct map 4K and large page paths\n\nThe two paths are equivalent except for one argument, which is already\navailable.
