This actually describes what is going on, rather than alerting the reader that something strange is going on. Signed-off-by:Avi Kivity <avi@redhat.com>

Zeroing on mmu_memory_cache_alloc is unnecessary since: - Smaller areas are pre-allocated with kmem_cache_zalloc. - Page pointed by ->spt is overwritten with prefetch_page and entries in page pointed by ->gfns are initialized before reading. [avi: zeroing pages is unnecessary] Signed-off-by:

While the PIT is masked the guest cannot ack the irq, so the reinject logic will never allow the interrupt to be injected. Fix by resetting the reinjection counters on unmask. Unbreaks Xen. Signed-off-by: -
Avi Kivity authored
Allow clients to request notifications when the guest masks or unmasks a particular irq line. This complements irq ack notifications, as the guest will not ack an irq line that is masked. Currently implemented for the ioapic only. Signed-off-by: -

Two KVM archs support irqchips and two don't. Add a Kconfig item to make selecting between the two models easier. Signed-off-by: -

Using kvm_mmu_lookup_page() will result in multiple scans of the hash chains; use hlist_for_each_entry_safe() to achieve a single scan instead. Signed-off-by: -

VMware ESX checks if the microcode level is correct when using a barcelona CPU, in order to see if it actually can use SVM. Let's tell it we're on the safe side... Signed-off-by:

MSI is always enabled by default for msi2intx=1. But if msi2intx=0, we have to disable MSI if guest require to do so. The patch also discard unnecessary msi2intx judgment if guest want to update MSI state. Notice KVM_DEV_IRQ_ASSIGN_MSI_ACTION is a mask which should cover all MSI related operations, though we only got one for now. Signed-off-by:

If we aren't doing mmio there's no need to exit to userspace (which will just be confused). Signed-off-by: -

Allow emulate_pop() to read into arbitrary memory rather than just the source operand. Needed for complicated instructions like far returns. Signed-off-by: -
Avi Kivity authored
If we've just emulated an instruction, we won't have any valid exit reason and associated information. Fix by moving the clearing of the emulation_required flag to the exit handler. This way the exit handler can notice that we've been emulating and abort early. Signed-off-by: -

The ususable bit is important for determining state validity; don't clobber it. Signed-off-by: -

The vmx guest state validity checks are full of bugs. Make them conform to the manual. Signed-off-by: -

Hollis Blanchard authored
The Book E code will be shared with e500. I've left PID in kvmppc_core_emulate_op() just so that we don't need to move kvmppc_set_pid() right now. Once we have the e500 implementation, we can probably share that too. Signed-off-by:

Certain clocks (such as TSC) in older 2.6 guests overaccount for lost ticks, causing severe time drift. Interrupt reinjection magnifies the problem. Provide an option to disable it. [avi: allow room for expansion in case we want to disable reinjection of other timers] Signed-off-by: -

Since we advertise MSR_VM_HSAVE_PA, userspace will attempt to read it even on Intel. Implement fake support for this MSR to avoid the warnings. Signed-off-by: -
