[PATCH] kvm: qemu: guard destroy memory regions to x86 only

From: Christian Ehrhardt ehrha...@linux.vnet.ibm.com Some parts of the changes made were arch specific e..g vga mem. This is a quick, but ugly workaround until a real arch split is found. Signed-off-by: Christian Ehrhardt ehrha...@linux.vnet.ibm.com Signed-off-by: Avi Kivity a...@redhat.com

[PATCH] kvm: qemu: Enable nested SVM support in userspace

From: Alexander Graf ag...@suse.de In order to use the new nested SVM support in KVM, we need to expose the SVM capability to the virtual machine. The current code masks this bit out. In order to expose the SVM capability to the guest, I added a -enable-nesting command line option, that makes

[PATCH] KVM: MMU: Inherit a shadow page's guest level count from vcpu setup

From: Avi Kivity a...@redhat.com Instead of calculating it on every shadow page allocation, set it once when switching modes, and copy it when allocating pages. This doesn't buy us much, but sets up the stage for inheriting more information related to the mmu setup. Signed-off-by: Avi Kivity

[PATCH] KVM: ia64: Code cleanup

From: Xiantao Zhang xiantao.zh...@intel.com Remove some unnecessary blank lines to accord with Kernel's coding style. Also remove vcpu_get_itir_on_fault due to no reference to it. Signed-off-by: Xiantao Zhang xiantao.zh...@intel.com Signed-off-by: Avi Kivity a...@redhat.com diff --git

[PATCH] KVM: ia64: stack get/restore patch

From: Jes Sorensen j...@sgi.com Implement KVM_IA64_VCPU_[GS]ET_STACK ioctl calls. This is required for live migrations. Patch is based on previous implementation that was part of old GET/SET_REGS ioctl calls. Signed-off-by: Jes Sorensen j...@sgi.com Signed-off-by: Avi Kivity a...@redhat.com

[PATCH] KVM: MMU: Initialize a shadow page's global attribute from cr4.pge

From: Avi Kivity a...@redhat.com If cr4.pge is cleared, we ought to treat any ptes in the page as non-global. This allows us to remove the check from set_spte(). Signed-off-by: Avi Kivity a...@redhat.com diff --git a/arch/x86/kvm/mmu.c b/arch/x86/kvm/mmu.c index 03dc21f..9871d9d 100644 ---

[PATCH] KVM: MMU: Segregate mmu pages created with different cr4.pge settings

From: Avi Kivity a...@redhat.com Don't allow a vcpu with cr4.pge cleared to use a shadow page created with cr4.pge set; this might cause a cr3 switch not to sync ptes that have the global bit set (the global bit has no effect if !cr4.pge). This can only occur on smp with different cr4.pge

Guillaume Thouvenin wrote: This patch emulates CPUID instruction. It should work but when I'm testing it in kvm-userspace, the cpuid instruction seems to have no effect (I mean eax == ebx == ecx == edx == 0x0). Should kvm_cpuid_emulate() be modified? Is cpuid instruction correctly implemented?
