/*
 * Drive Tables.
 *
 * The structure and option definitions can be
 * found in <sys/scsi/targets/stdef.h>.
 *
 * Note: that blocksize should be a power of two
 * for fixed-length recording devices.
 *
 * Note: the speed codes are unused at present.
 * The driver turns around whatever is reported
 * from the drive via the mode sense.
 *
 * Note: the read retry and write retry counts
 * are there to provide a limit until warning
 * messages are printed.
 *
 *
 * Note: For drives that are not in this table....
 *
 * The first open of the device will cause a MODE SENSE command
 * to be sent. From that we can determine block size. If block
 * size is zero, than this drive is in variable-record length
 * mode. The driver uses the SCSI-2 specification density codes in
 * order to attempt to determine what kind of sequential access
 * device this is. This will allow determination of 1/4" cartridge,
 * 1/2" cartridge, some helical scan (3.81 && 8 mm cartridge) and
 * 1/2" reel tape devices. The driver will print what it finds and is
 * assuming to the console. If the device you have hooked up returns
 * the default density code (0) after power up, the drive cannot
 * determine what kind of drive it might be, so it will assume that
 * it is an unknown 1/4" cartridge tape (QIC).
 *
 * If the drive is determined in this way to be a 1/2" 9-track reel
 * type device, an attempt will be mode to put it in Variable
 * record length mode.
 *
 * Generic drives are assumed to support only the long erase option
 * and will not to be run in buffered mode.
 */

/*
 * Format for Tape Drive Entry
 *
 * Please maintain the format currently in use for defining the properties
 * associated with each tape drive. This format is intended to make the
 * entries more readable and help increase the accuracy of the entries.
 * See the actual entries for examples of what they should look like.
 *
 * Important points to note about the format:
 *
 * 1. The opening and closing braces are indented 2 spaces.
 * 2. Each line in the entry is indented 4 spaces.
 * 3. The numerical values and text in the .options comments are indented two
 *    spaces in the comment block.
 * 4. The maximum line width is 80 columns; do not exceed this.
 * 5. The comment delimiters should line up, per the example.
 * 6. The OR symbol (|) should line up for multiple options.
 * 7. Hexadecimal values should be capitalized, for consistency.
 * 8. The leading / in the comment block header is indented 2 spaces and the
 *    susequent *'s should all line up.
 * 9. Order of the entries is very important. There are several groups of
 *    entries where the last entry in the grouping acts as a catch-all. If you
 *    place an entry after the catch-all, it will never be used by the driver.
 * 10. TABs should not be used anywhere between the BEGIN CSTYLED and
 *    END CSTYLED lines.

/*
 * Supported Drive Options
 *
 * The descriptions for the supported drive options are taken from stdef.h.
 *
 * ST_VARIABLE                          Device supports variable length record
 *                                      sizes.
 * ST_QIC                               QIC tape device.
 * ST_REEL                              1/2-inch reel tape device.
 * ST_BSF                               Device supports backspace file as in
 *                                      mt(1) bsf backspace over EOF marks.
 *                                      Devices not supporting bsf will fail
 *                                      with ENOTTY upon use of bsf.
 * ST_BSR                               Device supports backspace record as in
 *                                      mt(1) bsr : backspace over records. If
 *                                      the device does not support bsr, the st
 *                                      driver emulates the action by rewinding
 *                                      the tape and using forward space file
 *                                      (fsf) to the correct file and then uses
 *                                      forward space record (fsr) to the
 *                                      correct record.
 * ST_LONG_ERASE                        Device needs a longer time than normal
 *                                      to erase.
 * ST_AUTODEN_OVERRIDE                  Autodensity override flag Device can
 *                                      figure out the tape density
 *                                      automatically,without issuing a mode-
 *                                      select/mode-sense.
 * ST_NOBUF                             Don't use buffered mode. This disables
 *                                      the device's ability for buffered writes
 *                                      i.e. The device acknowledges write
 *                                      completion after the data is written to
 *                                      the device's buffer, but before all the
 *                                      data is actually written to tape.
 * ST_RESERVED_BIT1                     Reserved bit parity while talking to it.
 * ST_KNOWS_EOD                         Device knows when EOD (End of Data) has
 *                                      been reached. If the device knows EOD,
 *                                      st uses fast file skipping. If it does
 *                                      not know EOD, file skipping happens one
 *                                      file at a time.
 * ST_UNLOADABLE                        Device will not complain if the st
 *                                      driver is unloaded & loaded again;
 *                                      e.g. will return the correct inquiry
 *                                      string.
 * ST_SOFT_ERROR_REPORTING              Do request or log sense on close to
 *                                      report soft errors.Currently only
 *                                      Exabyte and DAT drives support this
 *                                      feature.
 * ST_LONG_TIMEOUTS                     Device needs 5 times longer timeouts
 *                                      for normal operation.
 * ST_BUFFERED_WRITES                   The data is buffered in the driver and
 *                                      pre-acked to the application.
 * ST_NO_RECSIZE_LIMIT                  For variable record size devices only.
 *                                      If flag is set,then don't limit record
 *                                      size to 64k as in pre-Solaris 2.4
 *                                      releases. The only limit on the record
 *                                      size will be the max record size the
 *                                      device can handle or the max DMA
 *                                      transfer size of the machine, which ever
 *                                      is smaller. Beware of incompatabilities
 *                                      with tapes of pre-Solaris 2.4 OS's
 *                                      written with large (>64k) block sizes,
 *                                      as their true block size is a max of
 *                                      approx 64k.
 * ST_MODE_SEL_COMP                     Use mode select of device configuration
 *                                      page (0x10) to enable/disable
 *                                      compression instead of density codes
 *                                      for the "c" and "u" devices.
 * ST_NO_RESERVE_RELEASE                For devices which do not support
 *                                      RESERVE/RELEASE SCSI command. If this
 *                                      is enabled then RESERVE/RELEASE would
 *                                      not be used during open/close for High
 *                                      Availability.
 * ST_READ_IGNORE_ILI                   This flag is only applicable to
 *                                      variable block devices which support
 *                                      the SILI bit option. It indicates that
 *                                      the SILI bit will be ignored during
 *                                      reads.
 * ST_READ_IGNORE_EOFS                  When this flag is set two EOF marks do
 *                                      not indicate an EOM. This option is
 *                                      only supported on 1/2" reel tapes.
 * ST_SHORT_FILEMARKS                   This option applies only to EXABYTE 8mm
 *                                      tape drives which support short
 *                                      filemarks. When this flag is set, short
 *                                      filemarks will be used for writing
 *                                      filemarks.
 * ST_EJECT_ON_CHANGER_FAILURE          When this flag is set and the tape is
 *                                      trapped in the medium changer, the
 *                                      tape is automatically ejected.
 * ST_RETRY_ON_RECOVERED_DEFERRED_ERROR This option applies only to IBM MAGSTAR
 *                                      3590. If this flag is set, the st
 *                                      driver will retry the last cmd if the
 *                                      last error cause a check condition with
 *                                      error code 0x71 and sense code 0x01.

   *
   *  o This is an unsupported drive.

   * [1] Low density is a vendor unique density code.
   *     This gives us 9 Track QIC-11. Supposedly the MT02 can
   *     read 4 Track QIC-11 while in this mode. If that doesn't
   *     work, change one of the duplicated QIC-24 fields to 0x4.
   * [2] The MT-02 has only one speed (if the driver ever cares).

   *     NOTES
   *     -----
   * [1] Compression on the 8900 is controlled via the Device Configuration mode
   *     page or the Data Compression page (either one). Even when enabled, the
   *     8900 automatically disables compression on-the-fly if it determines
   *     that it cannot achieve a reasonable compression ratio on the data.
   * [2] The 8900 can write in only one format, which is selected overtly by
   *     setting Density Code in the block descriptor to 27h; in addition to
   *     this native format, the 8900 can read tapes written in 8200, 8500 and
   *     8500-compressed formats. We set the density to 27h at all times: we
   *     _can_ do this because the format is changed automatically to match the
   *     data on any previously-written tape; we _must_ do this to ensure that
   *     never-before-written 8900 AME tapes are written in "8900 format" (all
   *     writes to them in any other format will fail). By establishing
   *     MT_DENSITY4 (corresponding to the "c" and "u" minor devices) as the
   *     default, applications which open '/dev/rmt/x' write compressed data
   *     automatically (but see Note [1]).
   * [3] The 8900 has only one speed (if the driver ever cares).
   * [4] max_rretries and max_wretries are driver anachronisms.

   *     NOTES

   *  o  The M4 Data 9303 is in non-buffered mode because it doesn't
   *     flush the buffer at end of tape writes. If you don't care
   *     about end of tape conditions (e.g., you use dump(8) which
   *     cannot handle end-of-tape anyhow), take out the ST_NOBUF.
   *
   *  o This is an unsupported drive.
   *
   * [1] The density code entry requires four values, even if there are less
   *     than four values for the drive.
   * [2] The M4 Data has only one speed (if the driver ever cares).
   * [3] max_rretries and max_wretries are driver anachronisms.
