Four patches to improve "classic" device assigment /wrt IRQs. Highlight is the last one that resolves the host IRQ sharing issue for all PCI 2.3 devices. Quite essential when passing non-MSI-ready devices like many USB host controllers. Changes in v2: - Reworked IRQ forwarding path to use threaded IRQs (direct signalling from IRQ context does not work out of the box and may be too lengthy) - Refactored host IRQ naming of assigned devices (cosmetic change) - Avoid unmask on ack when the next IRQ is pending, rather reassert the guest line (PCI-2.3 patch) - Refactored PCI-2.3 patch (but still no control knob for shared mode - is that a must?) Jan Kiszka (4): KVM: Clear assigned guest IRQ on release KVM: Switch assigned device IRQ forwarding to threaded handler KVM: Refactor IRQ names of assigned devices KVM: Allow host IRQ sharing for passed-through PCI 2.3 devices include/linux/kvm_host.h | 14 +-- virt/kvm/assigned-dev.c | 279 +++++++++++++++++++++++++++++++++------------ 2 files changed, 208 insertions(+), 85 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
