85 To automatically use MSI or MSI-X interrupt vectors, use the following
91 which allocates up to max_vecs interrupt vectors for a PCI device.  It
92 returns the number of vectors allocated or a negative error.  If the device
93 has a requirements for a minimum number of vectors the driver can pass a
95 if it can't meet the minimum number of vectors.
104 vectors, use the following function:
117 MSI interrupt vectors must be allocated consecutively, so the system might
118 not be able to allocate as many vectors for MSI as it could for MSI-X.  On
125 The typical usage of MSI or MSI-X interrupts is to allocate as many vectors
129 vectors supported beforehand:
171 vectors: pci_msi_vec_count() and pci_msix_vec_count().  In general these
173 number of vectors.  If you have a legitimate special use case for the count
174 of vectors we might have to revisit that decision and add a
