2008-10-15KVM: x86: Silence various LAPIC-related host kernel messagesJan Kiszka
KVM-x86 dumps a lot of debug messages that have no meaning for normal operation: - INIT de-assertion is ignored - SIPIs are sent and received - APIC writes are unaligned or < 4 byte long (Windows Server 2003 triggers this on SMP) Degrade them to true debug messages, keeping the host kernel log clean for real problems.

2008-10-15KVM: PIC: enhance IPI avoidanceMarcelo Tosatti
The PIC code makes little effort to avoid kvm_vcpu_kick(), resulting in unnecessary guest exits in some conditions. For example, if the timer interrupt is routed through the IOAPIC, IRR for IRQ 0 will get set but not cleared, since the APIC is handling the acks. This means that everytime an interrupt < 16 is triggered, the priority logic will find IRQ0 pending and send an IPI to vcpu0 (in case IRQ0 is not masked, which is Linux's case). Introduce a new variable isr_ack to represent the IRQ's for which the guest has been signalled / cleared the ISR. Use it to avoid more than one IPI per trigger-ack cycle, in addition to the avoidance when ISR is set in get_priority().

2008-10-15KVM: MMU: out of sync shadow coreMarcelo Tosatti
Allow guest pagetables to go out of sync. Instead of emulating write accesses to guest pagetables, or unshadowing them, we un-write-protect the page table and allow the guest to modify it at will. We rely on invlpg executions to synchronize individual ptes, and will synchronize the entire pagetable on tlb flushes.

2008-10-15KVM: MMU: do not write-protect large mappingsMarcelo Tosatti
There is not much point in write protecting large mappings. This can only happen when a page is shadowed during the window between is_largepage_backed and mmu_lock acquision. Zap the entry instead, so the next pagefault will find a shadowed page via is_largepage_backed and fallback to 4k translations. Simplifies out of sync shadow.
