Hi Joerg
The problem is this block of code in set_cr0
#ifdef CONFIG_X86_64
if (vcpu->arch.shadow_efer & EFER_LME) {
if (!is_paging(vcpu) && (cr0 & X86_CR0_PG))
enter_lmode(vcpu);
if (is_paging(vcpu) && !(cr0 & X86_CR0_PG))
exit_lmode(vcpu);
}
#endif
and
static inli

By moving the SVM feature detection from the each_cpu code to the hardware
setup code it runs only once. As an additional advance the feature check is now
available earlier in the module setup process.

Let SVM detect if the Nested Paging feature is available on the hardware.
Disable it to keep this patch series bisectable.

Hi,
here is the improved patchset which adds support for the Nested Paging
feature of the AMD Barcelona and Phenom processors to KVM. The patch set
was successfully install- and runtime-tested with various guest
operating systems (64 bit, 32 bit legacy and 32 bit PAE Linux,
Windows 64 bit and 32 b
The mapping function for the nonpaging case in the softmmu does basically the
same as required for Nested Paging. Make this function generic so it can be
used for both.

This patch contains the changes to the KVM MMU necessary for support of the

To disable the use of the Nested Paging feature even if it is available in
hardware this patch adds a module parameter. Nested Paging can be disabled by
passing npt=0 to the kvm_amd module.

The generic x86 code has to know if the specific implementation uses Nested
Paging. In the generic code Nested Paging is called Two Dimensional Paging
(TDP) to avoid confusion with (future) TDP implementations of other vendors.
This patch exports the availability of TDP to the generic x86 code.

The load_pdptrs() function is required in the SVM module for NPT support.

Actually having good Real Mode support will really help KVM running wider
variety of guest OSes.
Very welcome move.
