31 * Common Interface for SCSI-3 Support driver.
33 * CISS claims to provide a common interface between a generic SCSI
34 * transport and an intelligent host adapter.
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.
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.
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.
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.
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
71 * More thanks must go to John Cagle at HP for the countless hours
72 * spent making this driver "work" with the MSA* series storage
73 * enclosures. Without his help (and nagging), this driver could not
74 * be used with these enclosures.
