Poul-Henning Kamp dc08ffec87 Device megapatch 4/6: 
Introduce d_version field in struct cdevsw, this must always be
initialized to D_VERSION.

Flip sense of D_NOGIANT flag to D_NEEDGIANT, this involves removing
four D_NOGIANT flags and adding 145 D_NEEDGIANT flags.

*
* SCSI I2O host adapter driver
*
* V1.08 2001/08/21 Mark_Salyzyn@adaptec.com
* - The 2000S and 2005S do not initialize on some machines,
* increased timeout to 255ms from 50ms for the StatusGet
* command.
* 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.
