They have the file(s) +/sys/sundev/ st_conf.c (older versions have st_reg.h). This has records +for setting up each device, e.g.: +{ + "ArchiveST 4mm DAT/DAT-DC", 14, "ARCHIVE python", 0x30, 512, + (ST_KNOWS_EOD | ST_BSF | ST_BSR | ST_VARIABLE), 5000, 5000, + {0, 0, 0, 0, }, {0, 0, 0, 0} +} + + The interesting part is the capabilities field. I guess we could +infer capabilities from the density perhaps? All drives supporting DAT +density does probably have ST_KNOWS_EOD | ST_BSF | ST_BSR | +ST_VARIABLE. + The Sun driver uses several st/mt fsf if ST_KNOWS_EOD is not present. + +Jonas + +*** src/sys/sys/mtio.h~ Thu Nov 18 04:07:52 1993 +--- src/sys/sys/mtio.h Fri Aug 5 11:12:14 1994 +*************** +*** 74,79 **** +--- 74,82 ---- + #define MTSETDNSTY 11 + #endif + ++ #define MTEOM 12 /* space to end of media */ ++ #define MTERASE 13 /* erase the whole tape */ ++ + /* structure for MTIOCGET - mag tape get status command */ + + struct mtget { +*** src/sys/scsi/st.c.orig Fri Aug 5 11:01:26 1994 +--- src/sys/scsi/st.c Fri Aug 5 11:13:00 1994 +*************** +*** 1152,1157 **** +--- 1152,1163 ---- + errcode = st_space(unit, number - nmarks, + SP_FILEMARKS, flags); + break; ++ case MTEOM: /* space to end of media */ ++ errcode = st_chkeod(unit, FALSE, &nmarks, flags); ++ if (errcode == ESUCCESS) ++ errcode = st_space(unit, 1, ++ SP_EOM, flags); ++ break; + case MTBSR: /* backward space record */ + number = -number; + case MTFSR: /* forward space record */ +*** src/sbin/st/st.c~ Thu Nov 18 00:05:24 1993 +--- src/sbin/st/st.c Fri Aug 5 11:14:41 1994 +*************** +*** 62,67 **** +--- 62,68 ---- + { "weof", MTWEOF, 0 }, + { "eof", MTWEOF, 0 }, + { "fsf", MTFSF, 1 }, ++ { "eom", MTEOM, 1 }, + { "bsf", MTBSF, 1 }, + { "fsr", MTFSR, 1 }, + { "bsr", MTBSR, 1 }, |
