20 * This driver supports the Adaptec I2O RAID and DPT SmartRAID V I2O boards.
21 *
22 * CREDITS:
23 * The original linux driver was ported to Linux by Karen White while at
24 * Dell Computer. It was ported from Bob Pasteur's (of DPT) original
25 * non-Linux driver. Mark Salyzyn and Bob Pasteur consulted on the original
26 * driver.
27 *
28 * 2.0 version of the driver by Deanna Bonds and Mark Salyzyn.
29 *
30 * HISTORY:
31 * The driver was originally ported to linux version 2.0.34
32 *
33 * V2.0 Rewrite of driver. Re-architectured based on i2o subsystem.
34 * This was the first full GPL version since the last version used
35 * i2osig headers which were not GPL. Developer Testing version.
36 * V2.1 Internal testing
37 * V2.2 First released version
38 *
39 * V2.3
40 * Changes:
41 * Added Raptor Support
42 * Fixed bug causing system to hang under extreme load with
43 * management utilities running (removed GFP_DMA from kmalloc flags)
44 *
45 *
46 * V2.4 First version ready to be submitted to be embedded in the kernel
47 * Changes:
48 * Implemented suggestions from Alan Cox
49 * Added calculation of resid for sg layer
50 * Better error handling
51 * Added checking underflow condtions
52 * Added DATAPROTECT checking
53 * Changed error return codes
54 * Fixed pointer bug in bus reset routine
55 * Enabled hba reset from ioctls (allows a FW flash to reboot and use the new
56 * FW without having to reboot)
57 * Changed proc output
58 *
59 * TODO:
60 * Add 64 bit Scatter Gather when compiled on 64 bit architectures
61 * Add sparse lun scanning
62 * Add code that checks if a device that had been taken offline is
63 * now online (at the FW level) when test unit ready or inquiry
64 * command from scsi-core
65 * Add proc read interface
66 * busrescan command
67 * rescan command
68 * Add code to rescan routine that notifies scsi-core about new devices
69 * Add support for C-PCI (hotplug stuff)
70 * Add ioctl passthru error recovery
71 *
72 * NOTES:
73 * The DPT card optimizes the order of processing commands. Consequently,
74 * a command may take up to 6 minutes to complete after it has been sent
75 * to the board.
76 *
77 * The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the
78 * interface files for Adaptec's management routines. These define the structures used
79 * in the ioctls. They are written to be portable. They are hard to read, but I need
80 * to use them 'as is' or I can miss changes in the interface.
