| H A D | portdrv.h | a1d5f18c Tue May 23 09:23:58 CDT 2017 Gabriele Paoloni <gabriele.paoloni@huawei.com> PCI/portdrv: Support multiple interrupts for MSI as well as MSI-X
Root Ports can generate several different interrupts using either MSI or
MSI-X, but we only support that for MSI-X. Ports that support MSI but not
MSI-X are currently limited to sharing a single interrupt.
Rename pcie_port_enable_msix() to pcie_port_enable_irq_vec() and extend it
to support multiple interrupts using either MSI-X (preferred) or MSI.
