25 * SCSI I2O host adapter driver
27 * V1.08 2001/08/21 Mark_Salyzyn@adaptec.com
28 * - The 2000S and 2005S do not initialize on some machines,
29 * increased timeout to 255ms from 50ms for the StatusGet
31 * V1.07 2001/05/22 Mark_Salyzyn@adaptec.com
32 * - I knew this one was too good to be true. The error return
33 * on ioctl commands needs to be compared to CAM_REQ_CMP, not
34 * to the bit masked status.
35 * V1.06 2001/05/08 Mark_Salyzyn@adaptec.com
36 * - The 2005S that was supported is affectionately called the
37 * Conjoined BAR Firmware. In order to support RAID-5 in a
38 * 16MB low-cost configuration, Firmware was forced to go
39 * to a Split BAR Firmware. This requires a separate IOP and
40 * Messaging base address.
41 * V1.05 2001/04/25 Mark_Salyzyn@adaptec.com
42 * - Handle support for 2005S Zero Channel RAID solution.
43 * - System locked up if the Adapter locked up. Do not try
44 * to send other commands if the resetIOP command fails. The
45 * fail outstanding command discovery loop was flawed as the
46 * removal of the command from the list prevented discovering
48 * - Comment changes to clarify driver.
49 * - SysInfo searched for an EATA SmartROM, not an I2O SmartROM.
50 * - We do not use the AC_FOUND_DEV event because of I2O.
52 * V1.04 2000/09/22 Mark_Salyzyn@adaptec.com, msmith@freebsd.org,
53 * lampa@fee.vutbr.cz and Scott_Long@adaptec.com.
54 * - Removed support for PM1554, PM2554 and PM2654 in Mode-0
55 * mode as this is confused with competitor adapters in run
57 * - critical locking needed in ASR_ccbAdd and ASR_ccbRemove
58 * to prevent operating system panic.
59 * - moved default major number to 154 from 97.
60 * V1.03 2000/07/12 Mark_Salyzyn@adaptec.com
61 * - The controller is not actually an ASR (Adaptec SCSI RAID)
62 * series that is visible, it's more of an internal code name.
63 * remove any visible references within reason for now.
64 * - bus_ptr->LUN was not correctly zeroed when initially
65 * allocated causing a possible panic of the operating system
67 * V1.02 2000/06/26 Mark_Salyzyn@adaptec.com
68 * - Code always fails for ASR_getTid affecting performance.
69 * - initiated a set of changes that resulted from a formal
70 * code inspection by Mark_Salyzyn@adaptec.com,
71 * George_Dake@adaptec.com, Jeff_Zeak@adaptec.com,
72 * Martin_Wilson@adaptec.com and Vincent_Trandoan@adaptec.com.
73 * Their findings were focussed on the LCT & TID handler, and
74 * all resulting changes were to improve code readability,
75 * consistency or have a positive effect on performance.
76 * V1.01 2000/06/14 Mark_Salyzyn@adaptec.com
77 * - Passthrough returned an incorrect error.
78 * - Passthrough did not migrate the intrinsic scsi layer wakeup
79 * on command completion.
80 * - generate control device nodes using make_dev and delete_dev.
81 * - Performance affected by TID caching reallocing.
82 * - Made suggested changes by Justin_Gibbs@adaptec.com
83 * - use splcam instead of splbio.
84 * - use cam_imask instead of bio_imask.
85 * - use u_int8_t instead of u_char.
86 * - use u_int16_t instead of u_short.
87 * - use u_int32_t instead of u_long where appropriate.
88 * - use 64 bit context handler instead of 32 bit.
89 * - create_ccb should only allocate the worst case
90 * requirements for the driver since CAM may evolve
91 * making union ccb much larger than needed here.
92 * renamed create_ccb to asr_alloc_ccb.
93 * - go nutz justifying all debug prints as macros
94 * defined at the top and remove unsightly ifdefs.
95 * - INLINE STATIC viewed as confusing. Historically
96 * utilized to affect code performance and debug
97 * issues in OS, Compiler or OEM specific situations.
98 * V1.00 2000/05/31 Mark_Salyzyn@adaptec.com
99 * - Ported from FreeBSD 2.2.X DPT I2O driver.
100 * changed struct scsi_xfer to union ccb/struct ccb_hdr
101 * changed variable name xs to ccb
102 * changed struct scsi_link to struct cam_path
103 * changed struct scsibus_data to struct cam_sim
104 * stopped using fordriver for holding on to the TID
105 * use proprietary packet creation instead of scsi_inquire
106 * CAM layer sends synchronize commands.
