23: ! --------------------------------------------------------
24: ! direct access routines to ATA device under Solaris/SPARC
25: ! --------------------------------------------------------
26: !
27: ! Information
28: ! -----------
29: !
30: ! In Solaris, programmer can pass SCSI command to target device directly
31: ! by using USCSI ioctl or using "scg" generic SCSI driver. But, such
32: ! method does not exist for ATA devices.
33: !
34: ! However, I can access Solaris kernel source because I am subscriber of
35: ! Source Foundation Program of Solaris. So, I can find method of
36: ! accessing ATA device directly. The method is to pack command in
37: ! undocumented structure and issue ioctl that appears only in kernel
38: ! source. Yes, that is the same way in using USCSI interface.
39: !
40: ! But, I met difficulty in disclosing this technique. I have signed NDA
41: ! with Sun that inhibits me not to violate their intellectual property.
42: !
43: ! Fortunately, Sun allows licensees to publish "Interfaces" if:
44: !
45: ! (1) he/she treats Solaris code as confidential
46: !
47: ! (2) and he/she doesn't incorporate Sun's code into his/her code
48: !
49: ! (3) and disclose enough information to use "Interface" to everyone.
50: !
51: ! So, I publish that technique in assembly code or object code because:
52: !
53: ! (1) I believe Sun's intellectural property is not invaded because I
54: ! didn't reveal any struct member and ioctl to non-licensee.
55: !
56: ! (2) no piece of kernel source is included in this code.
57: !
58: ! (3) And finally, I publish enough information below in order to use
59: ! this code.
60: !
61: ! For last reason, please don't remove "Calling Interface" section from
62: ! distribution.
63: !
64: !
65: ! Calling Interface
66: ! -----------------
67: !
68: ! Name of function/macro presents corresponding S.M.A.R.T. command.
69: !
70: ! Parameters are described below.
71: !
72: ! int fd
73: !
74: ! File descriptor of ATA device. Device would be
75: ! /dev/rdsk/cXtXdXsX.
76: !
77: ! Device should be raw device serviced by "dada" driver. ATAPI
78: ! CD-ROM/R/RW, DVD-ROM, and so on are not allowed because they are
79: ! serviced by "sd" driver. On x86 Solaris, "cmdk" driver services
80: ! them, this routines doesn't work.
81: !
82: ! int s
83: ! Select sector for service. For example, this indicates log sector
84: ! number for smart_read_log() function. Probably you need to read
85: ! ATA specification for this parameter.
86: !
87: ! void *data
88: ! Data going to be read/written. It don't have to be word aligned,
89: ! But data shall points valid user memory space.
90: !
91: ! This is very tiny routines, but if you feel this insufficient, please
92: ! let me know.
