[Xen-devel] [PATCH v4] x86/pt: fix binding of MSIX entries already unmasked

[Roger Pau Monne <roger.pau@xxxxxxxxxx>]

Hello,

The following two patches fix an issue where a MSIX interrupt bound to
a guest when the MSIX entry is already unmasked would be left masked,
and thus the guest would not receive any interrupts from the device.

This is fixed by adding a new flag to the gflags field used in
XEN_DOMCTL_bind_pt_irq so that the caller can request the interrupt to
be unmasked once bound.

Thanks, Roger.
