* KVM: MMU: store generation-number into mmio spteXiao Guangrong2013-06-271-4/+6
| | | | | | | | | | | | | | | | Store the generation-number into bit3 ~ bit11 and bit52 ~ bit61, totally 19 bits can be used, it should be enough for nearly all most common cases In this patch, the generation-number is always 0, it will be changed in the later patch [Gleb: masking generation bits from spte in get_mmio_spte_gfn() and get_mmio_spte_access()] Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Reviewed-by: Gleb Natapov <gleb@redhat.com> Reviewed-by: Marcelo Tosatti <mtosatti@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

| | | | | | | | | | | | | Using kvm_mmu_prepare_zap_page() and kvm_mmu_commit_zap_page() to split kvm_mmu_zap_page() function, then we can: - traverse hlist safely - easily to gather remote tlb flush which occurs during page zapped Those feature can be used in the later patches Signed-off-by: Xiao Guangrong <xiaoguangrong@cn.fujitsu.com> Signed-off-by: Avi Kivity <avi@redhat.com>

* KVM: MMU: Drop cr4.pge from shadow page roleAvi Kivity2010-05-171-2/+1
| | | | | | | | | | Since commit bf47a760f66ad, we no longer handle ptes with the global bit set specially, so there is no reason to distinguish between shadow pages created with cr4.gpe set and clear. Such tracking is expensive when the guest toggles cr4.pge, so drop it. Signed-off-by: Avi Kivity <avi@redhat.com>
* KVM: MMU: Replace role.glevels with role.cr4_paeAvi Kivity2010-05-171-2/+3
| | | | | | | | | | | | | There is no real distinction between glevels=3 and glevels=4; both have exactly the same format and the code is treated exactly the same way. Drop role.glevels and replace is with role.cr4_pae (which is meaningful). This simplifies the code a bit. As a side effect, it allows sharing shadow page tables between pae and longmode guest page tables at the same guest page.
