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

2007-10-22T10:03:29+00:00

When resetting from userspace, we need to handle the flags being cleared
even after we are in real mode.

KVM: VMX: Reset mmu context when entering real mode

2007-10-22T10:03:28+00:00

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: Handle NMIs before enabling interrupts and preemption

2007-10-22T10:03:28+00:00

This makes sure we handle NMI on the current cpu, and that we don't service
maskable interrupts before non-maskable ones.

KVM: VMX: Fix exit qualification width on i386

2007-10-13T08:18:28+00:00

According to Intel Software Developer's Manual, Vol. 3B, Appendix H.4.2,
exit qualification should be of natural width. However, current code
uses u64 as the data type for this register, which occasionally
introduces invalid value to VMExit handling logics. This patch fixes
this bug.

I have tested Windows and Linux guest on i386 host, and they can boot
successfully with this patch.

KVM: Rename kvm_arch_ops to kvm_x86_ops

2007-10-13T08:18:27+00:00

This patch just renames the current (misnamed) _arch namings to _x86 to
ensure better readability when a real arch layer takes place.

KVM: enable in-kernel APIC INIT/SIPI handling

2007-10-13T08:18:26+00:00

This patch enables INIT/SIPI handling using in-kernel APIC by
introducing a ->mp_state field to emulate the SMP state transition.

KVM: Migrate lapic hrtimer when vcpu moves to another cpu

2007-10-13T08:18:26+00:00

This reduces overhead by accessing cachelines from the wrong node, as well
as simplifying locking.
