2010-05-19KVM: VMX: Atomically switch efer if EPT && !EFER.NXAvi Kivity1-0/+12
When EPT is enabled, we cannot emulate EFER.NX=0 through the shadow page tables. This causes accesses through ptes with bit 63 set to succeed instead of failing a reserved bit check. Signed-off-by: Avi Kivity <[email protected]>
2010-05-19KVM: VMX: Add facility to atomically switch MSRs on guest entry/exitAvi Kivity1-0/+49
Some guest msr values cannot be used on the host (for example. EFER.NX=0), so we need to switch them atomically during guest entry or exit. Add a facility to program the vmx msr autoload registers accordingly. Signed-off-by: Avi Kivity <[email protected]>

vmx and svm vcpus have different contents and therefore may have different alignmment requirements. Let each specify its required alignment. Signed-off-by: Avi Kivity <[email protected]>

2010-05-19KVM: Fix mmu shrinker errorGui Jianfeng1-5/+5
kvm_mmu_remove_one_alloc_mmu_page() assumes kvm_mmu_zap_page() only reclaims only one sp, but that's not the case. This will cause mmu shrinker returns a wrong number.

2010-05-17x86, hweight: Use a 32-bit popcnt for __arch_hweight32()H. Peter Anvin1-4/+6
Use a 32-bit popcnt instruction for __arch_hweight32(), even on x86-64. Even though the input register will *usually* be zero-extended due to the standard operation of the hardware, it isn't necessarily so if the input value was the result of truncating a 64-bit operation. Note: the POPCNT32 variant used on x86-64 has a technically unnecessary REX prefix to make it five bytes long, the same as a CALL instruction, therefore avoiding an unnecessary NOP.

2010-05-17KVM: x86: Allow marking an exception as reinjectedJoerg Roedel4-12/+32
This patch adds logic to kvm/x86 which allows to mark an injected exception as reinjected. This allows to remove an ugly hack from svm_complete_interrupts that prevented exceptions from being reinjected at all in the nested case. The hack was necessary because an reinjected exception into the nested guest could cause a nested vmexit emulation. But reinjected exceptions must not intercept. The downside of the hack is that a exception that in injected could get lost. This patch fixes the problem and puts the code for it into generic x86 files because. Nested-VMX will likely have the same problem and could reuse the code. Signed-off-by: Joerg Roedel <[email protected]> Signed-off-by: Avi Kivity <[email protected]>
2010-05-17KVM: SVM: Report emulated SVM features to userspaceJoerg Roedel1-0/+10
