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 condtions * 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 Adaptecs managment 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. * */ |
