Xiong Zhang bed8b0017d vfio: Add msi support ... crosvm doesn't support MSI/MSI-x, but kvmgt vgpu support MSI only through cfg msi capability. This is a simple msi implementation, it detects msi capability and track msi control, data and address info, then call vfio kernel to enable / disable msi interrupt. Currently it supports one vetor per MSI. It could extend to multi vetors and MSI-x.
