Next: [PATCH 14/22] KVM: MMU: Make walk_addr_generic capable for two-level walking
From: Joerg Roedel on 27 Apr 2010 06:50 Hi, this is the second and reworked version of my nested paging for nested svm patchset. Changes to the previous version include: * Renamed mmu.tdp_enabled to mmu.direct_map * Introduced two helper functions to read physical memory locations of the current running guest level * Fixed a couple of bugs were KVM needs to read l2 physical memory and others This patchset is tested with KVM and Windows 7 XPmode. I also tested in KVM with Linux and Windows 7 as l2 guests. I also tested different pagesize combinations and did a stress tests for a couple of hours. All these tests showed no introduced regressions. Please review this second version of the patch-set. I appreciate your feedback.
