Account for number of online cpus and use that in loops iterating over the list of vpus instead of scanning the full array unconditionally. This patch is a building block to facilitate allowing to bump up the size of MAX_VCPUS significantly. Signed-off-by:

This patch fixes the SET PREFIX interrupt if triggered by userspace. Until now, it was not necessary, but life migration will need it. In addition, it helped me creating SMP support for my kvm_crashme tool (lets kvm execute random guest memory content). Signed-off-by:

The kernel handles some priviledged instruction exits. While I was unable to trigger such an exit from guest userspace, the code should check for supervisor state before emulating a priviledged instruction. I also renamed kvm_s390_handle_priv to kvm_s390_handle_b2. After all there are non priviledged b2 instructions like stck (store clock). Signed-off-by:

KVM on s390 does not support the ESA/390 architecture. We refuse to change the architecture mode and print a warning. This patch removes the printk for several reasons: o A malicious guest can flood host dmesg o The old message had no newline o there is no connection between the message and the failing guest This patch simply removes the printk. We already set the condition code to 3 - the guest knows that something went wrong. Reported-by:

For windows 2008, it needs more pal calls to implement for booting. In addition, also changes the name of set_{sal, pal}_call_result to get_{sal,pal}_call_result for readability. Signed-off-by:Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by:

Kconfig symbols are not available in userspace, and are not stripped by headers-install. Avoid their use by adding #defines in <asm/kvm.h> to suit each architecture. Signed-off-by: -

Currently KVM has a static routing from GSI numbers to interrupts (namely, 0-15 are mapped 1:1 to both PIC and IOAPIC, and 16:23 are mapped 1:1 to the IOAPIC). This is insufficient for several reasons: - HPET requires non 1:1 mapping for the timer interrupt - MSIs need a new method to assign interrupt numbers and dispatch them - ACPI APIC mode needs to be able to reassign the PCI LINK interrupts to the ioapics This patch implements an interrupt routing table (as a linked list, but this can be easily changed) and a userspace interface to replace the table. The routing table is initialized according to the current hardwired mapping. Signed-off-by: -

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: -

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:

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: -
