Ack all. This also solved one bug by my hand. Thanks!
I observe one point: the performance of high workload interrupt(e.g. 10
gigabyte oplin card) dropped dramatically with smp_send_reschedule() method...
In one environment(the speed of oplin card also limited by cpu performance),
Using smp_call
Intel TXT(Trusted Execution Technology) required VMX off for all cpu to work
when system shutdown.

But AFAIK, the drivers handle it well.
The patch fixed the oplin card performance issue(MSI-X performance is half of
MSI/INTx).

Hi Avi & Marcelo
This patchset would add emulation of MSI-X mask bit for assigned devices in
QEmu.
BTW: We are also purposed an acceleration of MSI-X mask bit for KVM - to get
it done in kernel. That's because sometime MSI-X mask bit was accessed very
frequently by guest and emulation in QEmu cos
This patch enable per-vector mask for assigned devices using MSI-X.

Also add flush_work() according to Marcelo's comments.
Sheng Yang (8):
PCI: MSI: Move MSI-X entry definition to pci_regs.h
irq: Export irq_to_desc() to modules
KVM: x86: Enable ENABLE_CAP capability for x86
KVM: Move struct kvm_io_device to kvm_host.h
KVM: Add kvm_get_irq_rou
Then it can be used in struct kvm_assigned_dev_kernel later.

KVM need to execute mask/unmask directly on MSI/MSI-X devices. The alternative
way of doing this is export mask_msi_irq(), but it lacks of checking if IRQ
type was really MSI.

The feature wouldn't be enabled until later patch set msix_flags_enabled. It
would be enabled along with mask support in kernel.
