2186 | * | |
2187 | * This routine is invoked to enable the MSI-X interrupt vectors. The kernel | |
2188 | * function pci_enable_msix() is called to enable the MSI-X vectors. Note that | |
2189 | * pci_enable_msix(), once invoked, enables either all or nothing, depending | |
2190 | * on the current availability of PCI vector resources. The device driver is | |
2191 | * responsible for calling the individual request_irq() to register each MSI-X | |
2192 | * vector with a interrupt handler, which is done in this function. Note that | |
2193 | * later when device is unloading, the driver should always call free_irq() | |
2194 | * on all MSI-X vectors it has done request_irq() on before calling | |
2195 | * pci_disable_msix(). Failure to do so results in a BUG_ON() and a device | |
2196 | * will be left with MSI-X enabled and leaks its vectors. | |
2197 | * | |
2198 | * Return codes | |
2199 | * 0 - sucessful | |
