Subject: RE: [PATCH V4 09/11] vfio/pci: Probe and store ability to support
 dynamic MSI-X

> From: Chatre, Reinette <reinette.chatre@...el.com>

> Not all MSI-X devices support dynamic MSI-X allocation. Whether
> a device supports dynamic MSI-X should be queried using
> pci_msix_can_alloc_dyn().
> 
> Instead of scattering code with pci_msix_can_alloc_dyn(),
> probe this ability once and store it as a property of the
> virtual device.
