We have to handle more than one interrupt with one handler for MSI-X. Avi suggested to use a flag to indicate the pending. So here is it. Signed-off-by: Sheng Yang --- include/linux/kvm_host.h |1 + virt/kvm/kvm_main.c | 66 +- 2 files

[PATCH 3/3] KVM: Enable MSI-X for KVM assigned device

idn't implement MSI-X mask all and mask single entry. I would implement the former in driver/pci/msi.c later. And for single entry, userspace should have reposibility to handle it. Signed-off-by: Sheng Yang --- arch/x86/include/asm/kvm.h |1 + include/linux/kvm.h|8
