11926 | * service routine when device with SLI-4 interface spec is enabled with | |
11927 | * MSI-X multi-message interrupt mode and there is a fast-path FCP IOCB | |
11928 | * ring event in the HBA. However, when the device is enabled with either | |
11929 | * MSI or Pin-IRQ interrupt mode, this function is called as part of the | |
11930 | * device-level interrupt handler. When the PCI slot is in error recovery | |
11931 | * or the HBA is undergoing initialization, the interrupt handler will not | |
11932 | * process the interrupt. The SCSI FCP fast-path ring event are handled in | |
11933 | * the intrrupt context. This function is called without any lock held. | |
11934 | * It gets the hbalock to access and update SLI data structures. Note that, | |
11935 | * the FCP EQ to FCP CQ are one-to-one map such that the FCP EQ index is | |
11936 | * equal to that of FCP CQ index. | |
11937 | * | |
67d12733 JS |
11938 | * The link attention and ELS ring attention events are handled |
11939 | * by the worker thread. The interrupt handler signals the worker thread | |
11940 | * and returns for these events. This function is called without any lock | |
11941 | * held. It gets the hbalock to access and update SLI data structures. | |
