  • contract, strict liability, or tort (including negligence or otherwise)
  • arising in any way out of the use of this driver software, even if advised
  • of the possibility of such damage.
  • This driver supports the Adaptec I2O RAID and DPT SmartRAID V I2O boards.
  • CREDITS:
  • The original linux driver was ported to Linux by Karen White while at
  • Dell Computer. It was ported from Bob Pasteur’s (of DPT) original
  • non-Linux driver. Mark Salyzyn and Bob Pasteur consulted on the original
  • driver.
  • 2.0 version of the driver by Deanna Bonds and Mark Salyzyn.
  • HISTORY:
  • The driver was originally ported to linux version 2.0.34
  • V2.0 Rewrite of driver. Re-architectured based on i2o subsystem.
  • This was the first full GPL version since the last version used
  • i2osig headers which were not GPL. Developer Testing version.
  • V2.1 Internal testing
  • V2.2 First released version
  • V2.3
  • Changes:
  •  Added Raptor Support

  •  Fixed bug causing system to hang under extreme load with 

  •     management utilities running (removed GFP_DMA from kmalloc flags)
  • V2.4 First version ready to be submitted to be embedded in the kernel
  • Changes: 
  •  Implemented suggestions from Alan Cox

  •  Added calculation of resid for sg layer

  •  Better error handling

  •     Added checking underflow conditions 

  •     Added DATAPROTECT checking

  •     Changed error return codes

  •     Fixed pointer bug in bus reset routine

  •  Enabled hba reset from ioctls (allows a FW flash to reboot and use the new

  •     FW without having to reboot)

  •  Changed proc output
  • TODO:
  •  Add 64 bit Scatter Gather when compiled on 64 bit architectures

  •  Add sparse lun scanning 

  •  Add code that checks if a device that had been taken offline is

  •     now online (at the FW level) when test unit ready or inquiry 

  •     command from scsi-core

  •  Add proc read interface

  •     busrescan command

  •     rescan command

  •  Add code to rescan routine that notifies scsi-core about new devices

  •  Add support for C-PCI (hotplug stuff)

  •  Add ioctl passthru error recovery
  • NOTES:
  • The DPT card optimizes the order of processing commands. Consequently,
  • a command may take up to 6 minutes to complete after it has been sent
  • to the board.
  • The files dpti_ioctl.h dptsig.h osd_defs.h osd_util.h sys_info.h are part of the
  • interface files for Adaptec’s management routines. These define the structures used
  • in the ioctls. They are written to be portable. They are hard to read, but I need
  • to use them ‘as is’ or I can miss changes in the interface.
