* KVM: Report IRQ injection status to userspace.Gleb Natapov2009-03-241-2/+10
| | | | | | | | | | | | IRQ injection status is either -1 (if there was no CPU found that should except the interrupt because IRQ was masked or ioapic was misconfigured or ...) or >= 0 in that case the number indicates to how many CPUs interrupt was injected. If the value is 0 it means that the interrupt was coalesced and probably should be reinjected. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Avi Kivity <avi@redhat.com>

| | | | | | | | | | | 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.

* KVM: Userspace controlled irq routingAvi Kivity2009-03-241-0/+5
| | | | | | | | | | | | | | | | | 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: Avi Kivity <avi@redhat.com>

* KVM: New guest debug interfaceJan Kiszka2009-03-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | This rips out the support for KVM_DEBUG_GUEST and introduces a new IOCTL instead: KVM_SET_GUEST_DEBUG. The IOCTL payload consists of a generic part, controlling the "main switch" and the single-step feature. The arch specific part adds an x86 interface for intercepting both types of debug exceptions separately and re-injecting them when the host was not interested. Moveover, the foundation for guest debugging via debug registers is layed. To signal breakpoint events properly back to userland, an arch-specific data block is now returned along KVM_EXIT_DEBUG. For x86, the arch block contains the PC, the debug exception, and relevant debug registers to tell debug events properly apart. The availability of this new interface is signaled by KVM_CAP_SET_GUEST_DEBUG. Empty stubs for not yet supported archs are provided. Note that both SVM and VTX are supported, but only the latter was tested yet. Based on the experience with all those VTX corner case, I would be fairly surprised if SVM will work out of the box.

* KVM: Add kvm_arch_sync_events to sync with asynchronize eventsSheng Yang2009-02-151-0/+4
| | | | | | | | | | | | | kvm_arch_sync_events is introduced to quiet down all other events may happen contemporary with VM destroy process, like IRQ handler and work struct for assigned device. For kvm_arch_sync_events is called at the very beginning of kvm_destroy_vm(), so the state of KVM here is legal and can provide a environment to quiet down other events.

* KVM: ia64: fix fp fault/trap handlerYang Zhang2009-02-151-8/+9
| | | | | | | | | | | | | | | The floating-point registers f6-f11 is used by vmm and saved in kvm-pt-regs, so should set the correct bit mask and the pointer in fp_state, otherwise, fpswa may touch vmm's fp registers instead of guests'. In addition, for fp trap handling, since the instruction which leads to fp trap is completely executed, so can't use retry machanism to re-execute it, because it may pollute some registers.

* KVM: ia64: Fix kvm_arch_vcpu_ioctl_[gs]et_regs()Jes Sorensen2008-12-311-30/+10Star
| | | | | | | | | | | | | | | | | | | | Fix kvm_arch_vcpu_ioctl_[gs]et_regs() to do something meaningful on ia64. Old versions could never have worked since they required pointers to be set in the ioctl payload which were never being set by the ioctl handler for get_regs. In addition reserve extra space for future extensions. The change of layout of struct kvm_regs doesn't require adding a new CAP since get/set regs never worked on ia64 until now. This version doesn't support copying the KVM kernel stack in/out of the kernel. This should be implemented in a seperate ioctl call if ever needed.
