KVM: VMX: Reset mmu context when entering real mode

2007-12-14T17:50:57Z

patch 8668a3c468ed55d19514117a5a959d91d3d03823 in mainline. Resetting an SMP guest will force AP enter real mode (RESET) with paging enabled in protected mode. While current enter_rmode() can only handle mode switch from nonpaging mode to real mode which leads to SMP reboot failure. Fix by reloading the mmu context on entering real mode.

KVM: VMX: Force vm86 mode if setting flags during real mode

2007-12-14T17:50:57Z

patch 78f7826868da8e27d097802139a3fec39f47f3b8 in mainline. When resetting from userspace, we need to handle the flags being cleared even after we are in real mode. Signed-off-by: Avi Kivity Signed-off-by: Greg Kroah-Hartman

KVM: VMX: Remove unnecessary code in vmx_tlb_flush()

2007-07-16T09:05:49Z

A vmexit implicitly flushes the tlb; the code is bogus. Noted by Shaohua Li. Signed-off-by: Avi Kivity

KVM: VMX: Reinitialize the real-mode tss when entering real mode

2007-07-16T09:05:48Z

Protected mode code may have corrupted the real-mode tss, so re-initialize it when switching to real mode. Signed-off-by: Avi Kivity

KVM: VMX: Fix interrupt checking on lightweight exit

2007-07-16T09:05:48Z

With kernel-injected interrupts, we need to check for interrupts on lightweight exits too. Signed-off-by: Gregory Haskins Signed-off-by: Avi Kivity

KVM: VMX: Ensure vcpu time stamp counter is monotonous

2007-07-16T09:05:47Z

If the time stamp counter goes backwards, a guest delay loop can become infinite. This can happen if a vcpu is migrated to another cpu, where the counter has a lower value than the first cpu. Since we're doing an IPI to the first cpu anyway, we can use that to pick up the old tsc, and use that to calculate the adjustment we need to make to the tsc offset. Signed-off-by: Avi Kivity

KVM: Flush remote tlbs when reducing shadow pte permissions

2007-07-16T09:05:46Z

When a vcpu causes a shadow tlb entry to have reduced permissions, it must also clear the tlb on remote vcpus. We do that by: - setting a bit on the vcpu that requests a tlb flush before the next entry - if the vcpu is currently executing, we send an ipi to make sure it exits before we continue Signed-off-by: Avi Kivity
