| 19 | **************************************************************** |
| 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 conditions |
| 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. |
