(Now with correct Cc-list. I accidentially copied the wrong line from MAINTAINERS in the first post of this. Sorry for the double-post) Hi Avi, Marcelo, here is finally the third round of my NPT virtualization patches for KVM. It took a while to get everything running (including KVM itself) on 32 bit again to actually test it. But testing on 32 bit host and with a 32 bit hypervisor was a very good idea. I found some serious bugs and shortcomings in my code that are fixed now in v3. The patchset was tested in a number of combinations: host(64|32e) ->kvm(shadow|npt) ->guest(64|32e|32) ->test(boot|kbuild) host(64|32e) ->kvm(npt) ->guest(64|32e|32) ->kvm(shadow|kvm) ->guest(64|32e|32) ->test(boot|kbuild) Only the valid combinations where tested of course, so no 64 bit on 32 bit combinations were tested. Except for that I tested all of the above combinations and all worked without any regressions. Other changes since v2 are: * Addressed the review comments from v2: - Rebased everything to latest upstream code - renamed nested_mmu to walk_mmu to make its meaning more clear - the gva_to_gpa functions are not longer swapped between the two mmu states which makes it more consistent - Moved struct vcpu page fault data into seperate sub-struct for better readability - Other minor stuff (coding style, typos) - Renamed the kvm_*_page_x86 functions to kvm_*_page_mmu so that they can be made more generic later. * Made everything work on 32 bit - Introduced mmu->lm_root pointer to let the softmmu shadow 32 bit page tables with a long-mode page table. The lm_root page-table root always just points to the mmu.pae_root, so this builds entirely on the pae-shadow code. - Split mmu_alloc_roots into a shadow and direct_map version to simplify the code and to not break the direct_map paths anymore when changing something in that function. * Probably other changes I forgot about This patchset applies on todays avi/master + the three patches I sent end of last week. These patches are necessary for some of the tests above to run. For the curious and impatient user I put everything in a branch on kernel.org. If you want to test it you can pull the tree from git://git.kernel.org/pub/scm/linux/kernel/git/joro/linux-2.6-kvm.git npt-virt-v3 Please review and/or apply these patches if considered good enough. Otherwise I appreciate your feedback.
