As an example, modern Intel CPUs in server platform can use this method to handle lowest-priority interrupts. v2: - Add vector-hashing support for non-vt-d PI case - Fix some bugs Radim pointed out in v1 - Use a module parameter to control the vector-hashing mechanism Feng Wu (2): KVM: x86: Use vector-hashing to deliver lowest-priority interrupts KVM: x86: Add lowest-priority support for vt-d posted-interrupts arch/x86/kvm/irq_comm.c | 27 +++++++++-- arch/x86/kvm/lapic.c | 124 ++++++++++++++++++++++++++++++++++++++++++++---- arch/x86/kvm/lapic.h | 4 ++ arch/x86/kvm/vmx.c | 12 ++++- arch/x86/kvm/x86.c | 9 ++++ arch/x86/kvm/x86.h | 1 + 6 files changed, 160 insertions(+), 17 deletions(-) -- 2.1.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
