| 31 | * Common Interface for SCSI-3 Support driver. |
| 32 | * |
| 33 | * CISS claims to provide a common interface between a generic SCSI |
| 34 | * transport and an intelligent host adapter. |
| 35 | * |
| 36 | * This driver supports CISS as defined in the document "CISS Command |
| 37 | * Interface for SCSI-3 Support Open Specification", Version 1.04, |
| 38 | * Valence Number 1, dated 20001127, produced by Compaq Computer |
| 39 | * Corporation. This document appears to be a hastily and somewhat |
| 40 | * arbitrarlily cut-down version of a larger (and probably even more |
| 41 | * chaotic and inconsistent) Compaq internal document. Various |
| 42 | * details were also gleaned from Compaq's "cciss" driver for Linux. |
| 43 | * |
| 44 | * We provide a shim layer between the CISS interface and CAM, |
| 45 | * offloading most of the queueing and being-a-disk chores onto CAM. |
| 46 | * Entry to the driver is via the PCI bus attachment (ciss_probe, |
| 47 | * ciss_attach, etc) and via the CAM interface (ciss_cam_action, |
| 48 | * ciss_cam_poll). The Compaq CISS adapters are, however, poor SCSI |
| 49 | * citizens and we have to fake up some responses to get reasonable |
| 50 | * behaviour out of them. In addition, the CISS command set is by no |
| 51 | * means adequate to support the functionality of a RAID controller, |
| 52 | * and thus the supported Compaq adapters utilise portions of the |
| 53 | * control protocol from earlier Compaq adapter families. |
| 54 | * |
| 55 | * Note that we only support the "simple" transport layer over PCI. |
| 56 | * This interface (ab)uses the I2O register set (specifically the post |
| 57 | * queues) to exchange commands with the adapter. Other interfaces |
| 58 | * are available, but we aren't supposed to know about them, and it is |
| 59 | * dubious whether they would provide major performance improvements |
| 60 | * except under extreme load. |
| 61 | * |
| 62 | * Currently the only supported CISS adapters are the Compaq Smart |
| 63 | * Array 5* series (5300, 5i, 532). Even with only three adapters, |
| 64 | * Compaq still manage to have interface variations. |
| 65 | * |
| 66 | * |
| 67 | * Thanks must go to Fred Harris and Darryl DeVinney at Compaq, as |
| 68 | * well as Paul Saab at Yahoo! for their assistance in making this |
| 69 | * driver happen. |
