26 | ======= | |

28 | The original linux driver was ported to Linux by Karen White while at | |
29 | Dell Computer. It was ported from Bob Pasteur's (of DPT) original | |
30 | non-Linux driver. Mark Salyzyn and Bob Pasteur consulted on the original | |
31 | driver. | |
32 | ||
33 | 2.0 version of the driver by Deanna Bonds and Mark Salyzyn. | |

35 | History | |
36 | ======= | |
37 | ||
38 | The driver was originally ported to linux version 2.0.34 | |

40 | ==== ========================================================================== | |
41 | V2.0 Rewrite of driver. Re-architectured based on i2o subsystem. | |
42 | This was the first full GPL version since the last version used | |
43 | i2osig headers which were not GPL. Developer Testing version. | |
44 | V2.1 Internal testing | |
45 | V2.2 First released version | |
46 | ||
47 | V2.3 Changes: | |
48 | ||
49 | - Added Raptor Support | |
50 | - Fixed bug causing system to hang under extreme load with | |
51 | - management utilities running (removed GFP_DMA from kmalloc flags) | |
52 | ||
53 | V2.4 First version ready to be submitted to be embedded in the kernel | |
54 | ||
55 | Changes: | |
56 | ||
57 | - Implemented suggestions from Alan Cox | |
58 | - Added calculation of resid for sg layer | |
59 | - Better error handling | |
60 | - Added checking underflow conditions | |
61 | - Added DATAPROTECT checking | |
62 | - Changed error return codes | |
63 | - Fixed pointer bug in bus reset routine | |
64 | - Enabled hba reset from ioctls (allows a FW flash to reboot and use | |
65 | the new FW without having to reboot) | |
66 | - Changed proc output | |
67 | ==== ========================================================================== | |
68 | ||
69 | TODO | |
70 | ==== | |
71 | - Add 64 bit Scatter Gather when compiled on 64 bit architectures | |
72 | - Add sparse lun scanning | |
73 | - Add code that checks if a device that had been taken offline is | |
74 | now online (at the FW level) when test unit ready or inquiry | |
75 | command from scsi-core | |
76 | - Add proc read interface | |
77 | - busrescan command | |
78 | - rescan command | |
79 | - Add code to rescan routine that notifies scsi-core about new devices | |
80 | - Add support for C-PCI (hotplug stuff) | |
81 | - Add ioctl passthru error recovery | |

83 | Notes | |
84 | ===== | |
85 | The DPT card optimizes the order of processing commands. Consequently, | |
86 | a command may take up to 6 minutes to complete after it has been sent | |
87 | to the board. | |
88 | ||
89 | The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the | |
90 | interface files for Adaptec's management routines. These define the structures used | |
91 | in the ioctls. They are written to be portable. They are hard to read, but I need | |
92 | to use them 'as is' or I can miss changes in the interface. |
