2004-05-05 14:19:43 +00:00
|
|
|
* V1.10 2004/05/05 scottl@freebsd.org
|
|
|
|
* - Massive cleanup of the driver to remove dead code and
|
|
|
|
* non-conformant style.
|
|
|
|
* - Removed most i386-specific code to make it more portable.
|
|
|
|
* - Converted to the bus_space API.
|
2002-05-14 01:09:03 +00:00
|
|
|
* V1.08 2001/08/21 Mark_Salyzyn@adaptec.com
|
|
|
|
* - The 2000S and 2005S do not initialize on some machines,
|
2001-08-21 19:58:16 +00:00
|
|
|
* increased timeout to 255ms from 50ms for the StatusGet
|
|
|
|
* command.
|
2002-05-14 01:09:03 +00:00
|
|
|
* V1.07 2001/05/22 Mark_Salyzyn@adaptec.com
|
|
|
|
* - I knew this one was too good to be true. The error return
|
|
|
|
* on ioctl commands needs to be compared to CAM_REQ_CMP, not
|
|
|
|
* to the bit masked status.
|
|
|
|
* V1.06 2001/05/08 Mark_Salyzyn@adaptec.com
|
|
|
|
* - The 2005S that was supported is affectionately called the
|
|
|
|
* Conjoined BAR Firmware. In order to support RAID-5 in a
|
|
|
|
* 16MB low-cost configuration, Firmware was forced to go
|
|
|
|
* to a Split BAR Firmware. This requires a separate IOP and
|
|
|
|
* Messaging base address.
|
|
|
|
* V1.05 2001/04/25 Mark_Salyzyn@adaptec.com
|
|
|
|
* - Handle support for 2005S Zero Channel RAID solution.
|
|
|
|
* - System locked up if the Adapter locked up. Do not try
|
|
|
|
* to send other commands if the resetIOP command fails. The
|
|
|
|
* fail outstanding command discovery loop was flawed as the
|
|
|
|
* removal of the command from the list prevented discovering
|
|
|
|
* all the commands.
|
|
|
|
* - Comment changes to clarify driver.
|
|
|
|
* - SysInfo searched for an EATA SmartROM, not an I2O SmartROM.
|
|
|
|
* - We do not use the AC_FOUND_DEV event because of I2O.
|
|
|
|
* Removed asr_async.
|
|
|
|
* V1.04 2000/09/22 Mark_Salyzyn@adaptec.com, msmith@freebsd.org,
|
|
|
|
* lampa@fee.vutbr.cz and Scott_Long@adaptec.com.
|
|
|
|
* - Removed support for PM1554, PM2554 and PM2654 in Mode-0
|
|
|
|
* mode as this is confused with competitor adapters in run
|
|
|
|
* mode.
|
|
|
|
* - critical locking needed in ASR_ccbAdd and ASR_ccbRemove
|
|
|
|
* to prevent operating system panic.
|
|
|
|
* - moved default major number to 154 from 97.
|
|
|
|
* V1.03 2000/07/12 Mark_Salyzyn@adaptec.com
|
|
|
|
* - The controller is not actually an ASR (Adaptec SCSI RAID)
|
|
|
|
* series that is visible, it's more of an internal code name.
|
|
|
|
* remove any visible references within reason for now.
|
|
|
|
* - bus_ptr->LUN was not correctly zeroed when initially
|
|
|
|
* allocated causing a possible panic of the operating system
|
|
|
|
* during boot.
|
|
|
|
* V1.02 2000/06/26 Mark_Salyzyn@adaptec.com
|
|
|
|
* - Code always fails for ASR_getTid affecting performance.
|
|
|
|
* - initiated a set of changes that resulted from a formal
|
|
|
|
* code inspection by Mark_Salyzyn@adaptec.com,
|
|
|
|
* George_Dake@adaptec.com, Jeff_Zeak@adaptec.com,
|
|
|
|
* Martin_Wilson@adaptec.com and Vincent_Trandoan@adaptec.com.
|
|
|
|
* Their findings were focussed on the LCT & TID handler, and
|
|
|
|
* all resulting changes were to improve code readability,
|
|
|
|
* consistency or have a positive effect on performance.
|
|
|
|
* V1.01 2000/06/14 Mark_Salyzyn@adaptec.com
|
|
|
|
* - Passthrough returned an incorrect error.
|
|
|
|
* - Passthrough did not migrate the intrinsic scsi layer wakeup
|
|
|
|
* on command completion.
|
|
|
|
* - generate control device nodes using make_dev and delete_dev.
|
|
|
|
* - Performance affected by TID caching reallocing.
|
|
|
|
* - Made suggested changes by Justin_Gibbs@adaptec.com
|
|
|
|
* - use splcam instead of splbio.
|
|
|
|
* - use cam_imask instead of bio_imask.
|
|
|
|
* - use u_int8_t instead of u_char.
|
|
|
|
* - use u_int16_t instead of u_short.
|
|
|
|
* - use u_int32_t instead of u_long where appropriate.
|
|
|
|
* - use 64 bit context handler instead of 32 bit.
|
|
|
|
* - create_ccb should only allocate the worst case
|
|
|
|
* requirements for the driver since CAM may evolve
|
|
|
|
* making union ccb much larger than needed here.
|
|
|
|
* renamed create_ccb to asr_alloc_ccb.
|
|
|
|
* - go nutz justifying all debug prints as macros
|
|
|
|
* defined at the top and remove unsightly ifdefs.
|
|
|
|
* - INLINE STATIC viewed as confusing. Historically
|
|
|
|
* utilized to affect code performance and debug
|
|
|
|
* issues in OS, Compiler or OEM specific situations.
|
|
|
|
* V1.00 2000/05/31 Mark_Salyzyn@adaptec.com
|
|
|
|
* - Ported from FreeBSD 2.2.X DPT I2O driver.
|
|
|
|
* changed struct scsi_xfer to union ccb/struct ccb_hdr
|
|
|
|
* changed variable name xs to ccb
|
|
|
|
* changed struct scsi_link to struct cam_path
|
|
|
|
* changed struct scsibus_data to struct cam_sim
|
|
|
|
* stopped using fordriver for holding on to the TID
|
|
|
|
* use proprietary packet creation instead of scsi_inquire
|
|
|
|
* CAM layer sends synchronize commands.
