Linux-2.6.12-rc2v2.6.12-rc2
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

496 * hosts.h: Change attach function to return int, not void.
497 Define number of device slots to allow for loadable devices.
498 Define tags to tell scsi module code what type of module we
499 are loading.
500
501 * scsi.c: Fix scan_scsis so that it can be run by a user process.
502 Do not use waiting loops - use up and down mechanism as long
503 as current != task[0].
504
505 * scsi.c(scan_scsis): Do not use stack variables for I/O - this
506 could be > 16Mb if we are loading a module at runtime (i.e. use
507 scsi_init_malloc to get some memory we know will be safe).
508
509 * scsi.c: Change dma freelist to be a set of pages. This allows
510 us to dynamically adjust the size of the list by adding more pages
511 to the pagelist. Fix scsi_malloc and scsi_free accordingly.
512
513 * scsi_module.c: Fix include.
514
515 * sd.c: Declare detach function. Increment/decrement module usage
516 count as required. Fix init functions to allow loaded devices.
517 Revalidate all new disks so we get the partition tables. Define
518 detach function.
519
520 * sr.c: Likewise.
521
522 * sg.c: Declare detach function. Allow attachment of devices on
523 loaded drivers.
524
525 * st.c: Declare detach function. Increment/decrement module usage
526 count as required.

569
570 * seagate.c: Explicitly include linux/config.h
571
572 * sg.c: Increment/decrement module usage count on open/close.
573

575 information for a valid command. Pass correct size down to
576 scsi_do_cmd.

689 command.
690
691 * scsi.c (scsi_times_out): Pass pid down so that we can protect
692 against race conditions.

707 we can deal with boards that do incomplete decoding of their
708 address lines for the bios chips, but I am not entirely sure.
709
710 * buslogic.c: Set forbidden_addr stuff if using a buggy board.
711
712 * aha1740.c: Test for NULL pointer in SCtmp. This should not
713 occur, but a nice message is better than a kernel segfault.

759 values depending upon bus type (i.e. use 1 if ISA, so we do not
760 hog memory). Use other patches which got lost from 1.1.68.
761
762 * aha1542.c: Spelling.
763

772 changes appear from some unknown corner of the universe.
773
774 * Throughout: Change COMMAND_SIZE() to use SCpnt->cmd_len.
775
776 * Throughout: Change info() low level function to take a Scsi_Host
777 pointer. This way the info function can return specific

809
810 * hosts.h: Add new field to Scsi_Hosts "block" to allow blocking
811 all I/O to certain other cards. Helps prevent problems with some
812 ISA motherboards.
813
814 * hosts.h: Add usage_count to Scsi_Host_Template.
815
816 * hosts.h: Add n_io_port to Scsi_Host (used when releasing module).

827 print correct function name.
828
829 * scsi.c: When incrementing usage count, walk block linked list
830 for host, and or in SCSI_HOST_BLOCK bit. When decrementing usage
831 count to 0, clear this bit to allow usage to continue, wake up
832 processes waiting.
833
834
835 * scsi_ioctl.c: If we have an info() function, call it, otherwise
836 if we have a "name" field, use it, else do nothing.
837
838 * sd.c, sr.c: Clear cmd_len field prior to each command we
839 generate.
840
841 * sd.h: Add "has_part_table" bit to rscsi_disks.
842
843 * sg.[c,h]: Add support for vendor specific 12 byte commands (i.e.
844 override command length in COMMAND_SIZE).
845
846 * sr.c: Bugfix from Gerd in photocd code.
847
848 * sr.c: Bugfix in get_sectorsize - always use scsi_malloc buffer -
849 we cannot guarantee that the stack is < 16Mb.

1129 read the partition table. Attempt to deduce the geometry from
1130 the partition table if possible. Only used by 53c[7,8]xx right
1131 now, but could be used by any device for which we have no way
1132 of identifying the geometry.
1133
1134 * sd.c: Use device letters instead of sd%d in a lot of messages.
1135
1136 * seagate.c: Fix bug that resulted in lockups with some devices.

1166
1167Tue Jul 26 21:36:58 1994 Eric Youngdale (eric@esp22)
1168
1169 * Linux 1.1.37 released.
1170
1171 * aha1542.c: Always call aha1542_mbenable, use new udelay
1172 mechanism so we do not wait a long time if the board does not
1173 implement this command.
1174
1175 * g_NCR5380.c: Remove #include <linux/config.h> and #if
1176 defined(CONFIG_SCSI_*).
1177
1178 * seagate.c: Likewise.
1179
1180 Next round of changes to support loadable modules. Getting closer
1181 now, still not possible to do anything remotely usable.
1182
1183 hosts.c: Create a linked list of detected high level devices.
1184 (scsi_register_device): New function to insert into this list.
1185 (scsi_init): Call scsi_register_device for each of the known high
1186 level drivers.
1187
1188 hosts.h: Add prototype for linked list header. Add structure
1189 definition for device template structure which defines the linked
1190 list.
1191
1192 scsi.c: (scan_scsis): Use linked list instead of knowledge about
1193 existing high level device drivers.
1194 (scsi_dev_init): Use init functions for drivers on linked list
1195 instead of explicit list to initialize and attach devices to high
1196 level drivers.
1197
1198 scsi.h: Add new field "attached" to scsi_device - count of number
1199 of high level devices attached.
1200
1201 sd.c, sr.c, sg.c, st.c: Adjust init/attach functions to use new
1202 scheme.
1203

1229
1230 * Linux 1.1.30 released.
1231
1232 * scsi.c (scan_scsis): Fix detection of some Toshiba CDROM drives
1233 that report themselves as disk drives.
1234
1235 * (Throughout): Use request.sem instead of request.waiting.
1236 Should fix swap problem with fdomain.
1237
1238Thu Jul 14 10:51:42 1994 Eric Youngdale (eric@esp22)
1239
1240 * Linux 1.1.29 released.
1241
1242 * scsi.c (scan_scsis): Add new devices to end of linked list, not
1243 to the beginning.
1244
1245 * scsi.h (SCSI_SLEEP): Remove brain dead hack to try to save
1246 the task state before sleeping.
1247
1248Sat Jul 9 15:01:03 1994 Eric Youngdale (eric@esp22)
1249
1250 More changes to eventually support loadable modules. Mainly
1251 we want to use linked lists instead of arrays because it is easier
1252 to dynamically add and remove things this way.
1253
1254 Quite a bit more work is needed before loadable modules are
1255 possible (and usable) with scsi, but this is most of the grunge
1256 work.
1257
1258 * Linux 1.1.28 released.
1259
1260 * scsi.c, scsi.h (allocate_device, request_queueable): Change
1261 argument from index into scsi_devices to a pointer to the
1262 Scsi_Device struct.
1263
1264 * Throughout: Change all calls to allocate_device,
1265 request_queueable to use new calling sequence.
1266
1267 * Throughout: Use SCpnt->device instead of
1268 scsi_devices[SCpnt->index]. Ugh - the pointer was there all along
1269 - much cleaner this way.
1270
1271 * scsi.c (scsi_init_malloc, scsi_free_malloc): New functions -
1272 allow us to pretend that we have a working malloc when we
1273 initialize. Use this instead of passing memory_start, memory_end
1274 around all over the place.
1275
1276 * scsi.h, st.c, sr.c, sd.c, sg.c: Change *_init1 functions to use
1277 scsi_init_malloc, remove all arguments, no return value.
1278
1279 * scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd
1280 structs.
1281
1282 * scsi.c (scsi_dev_init): Set up for scsi_init_malloc.
1283 (scan_scsis): Get SDpnt from scsi_init_malloc, and refresh
1284 when we discover a device. Free pointer before returning.
1285 Change scsi_devices into a linked list.
1286
1287 * scsi.c (scan_scsis): Change to only scan one host.
1288 (scsi_dev_init): Loop over all detected hosts, and scan them.
1289
1290 * hosts.c (scsi_init_free): Change so that number of extra bytes
1291 is stored in struct, and we do not have to pass it each time.
1292
1293 * hosts.h: Change Scsi_Host_Template struct to include "next" and
1294 "release" functions. Initialize to NULL in all low level
1295 adapters.
1296
1297 * hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked
1298 list scsi_hosts, linked together with the new "next" field.
1299
1300Wed Jul 6 05:45:02 1994 Eric Youngdale (eric@esp22)
1301
1302 * Linux 1.1.25 released.
1303
1304 * aha152x.c: Changes from Juergen - cleanups and updates.
1305
1306 * sd.c, sr.c: Use new check_media_change and revalidate
1307 file_operations fields.
1308
1309 * st.c, st.h: Add changes from Kai Makisara, dated Jun 22.
1310
1311 * hosts.h: Change SG_ALL back to 0xff. Apparently soft error
1312 in /dev/brain resulted in having this bumped up.
1313 Change first parameter in bios_param function to be Disk * instead
1314 of index into rscsi_disks.
1315
1316 * sd_ioctl.c: Pass pointer to rscsi_disks element instead of index
1317 to array.
1318
1319 * sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk.
1320
1321 * scsi.c: Remove redundant Maxtor XT8760S from blacklist.
1322 In scsi_reset, add printk when DEBUG defined.
1323
1324 * All low level drivers: Modify definitions of bios_param in
1325 appropriate way.
1326
1327Thu Jun 16 10:31:59 1994 Eric Youngdale (eric@esp22)
1328
1329 * Linux 1.1.20 released.
1330
1331 * scsi_ioctl.c: Only pass down the actual number of characters
1332 required to scsi_do_cmd, not the one rounded up to a even number
1333 of sectors.
1334
1335 * ultrastor.c: Changes from Caleb Epstein for 24f cards. Support
1336 larger SG lists.
1337
1338 * ultrastor.c: Changes from me - use scsi_register to register
1339 host. Add some consistency checking,
1340
1341Wed Jun 1 21:12:13 1994 Eric Youngdale (eric@esp22)
1342
1343 * Linux 1.1.19 released.
1344
1345 * scsi.h: Add new return code for reset() function:
1346 SCSI_RESET_PUNT.
1347
1348 * scsi.c: Make SCSI_RESET_PUNT the same as SCSI_RESET_WAKEUP for
1349 now.
1350
1351 * aha1542.c: If the command responsible for the reset is not
1352 pending, return SCSI_RESET_PUNT.
1353
1354 * aha1740.c, buslogic.c, wd7000.c, ultrastor.c: Return
1355 SCSI_RESET_PUNT instead of SCSI_RESET_SNOOZE.
1356
1357Tue May 31 19:36:01 1994 Eric Youngdale (eric@esp22)
1358
1359 * buslogic.c: Do not print out message about "must be Adaptec"
1360 if we have detected a buslogic card. Print out a warning message
1361 if we are configuring for >16Mb, since the 445S at board level
1362 D or earlier does not work right. The "D" level board can be made
1363 to work by flipping an undocumented switch, but this is too subtle.
1364
1365 Changes based upon patches in Yggdrasil distribution.
1366
1367 * sg.c, sg.h: Return sense data to user.
1368
1369 * aha1542.c, aha1740.c, buslogic.c: Do not panic if
1370 sense buffer is wrong size.
1371
1372 * hosts.c: Test for ultrastor card before any of the others.
1373
1374 * scsi.c: Allow boot-time option for max_scsi_luns=? so that
1375 buggy firmware has an easy work-around.
1376
1377Sun May 15 20:24:34 1994 Eric Youngdale (eric@esp22)
1378
1379 * Linux 1.1.15 released.
1380
1381 Post-codefreeze thaw...
1382
1383 * buslogic.[c,h]: New driver from David Gentzel.
1384
1385 * hosts.h: Add use_clustering field to explicitly say whether
1386 clustering should be used for devices attached to this host
1387 adapter. The buslogic board apparently supports large SG lists,
1388 but it is apparently faster if sd.c condenses this into a smaller
1389 list.
1390
1391 * sd.c: Use this field instead of heuristic.
1392
1393 * All host adapter include files: Add appropriate initializer for
1394 use_clustering field.
1395
1396 * scsi.h: Add #defines for return codes for the abort and reset
1397 functions. There are now a specific set of return codes to fully
1398 specify all of the possible things that the low-level adapter
1399 could do.
1400
1401 * scsi.c: Act based upon return codes from abort/reset functions.
1402
1403 * All host adapter abort/reset functions: Return new return code.
1404
1405 * Add code in scsi.c to help debug timeouts. Use #define
1406 DEBUG_TIMEOUT to enable this.
1407
1408 * scsi.c: If the host->irq field is set, use
1409 disable_irq/enable_irq before calling queuecommand if we
1410 are not already in an interrupt. Reduce races, and we
1411 can be sloppier about cli/sti in the interrupt routines now
1412 (reduce interrupt latency).
1413
1414 * constants.c: Fix some things to eliminate warnings. Add some
1415 sense descriptions that were omitted before.
1416
1417 * aha1542.c: Watch for SCRD from host adapter - if we see it, set
1418 a flag. Currently we only print out the number of pending
1419 commands that might need to be restarted.
1420
1421 * aha1542.c (aha1542_abort): Look for lost interrupts, OGMB still
1422 full, and attempt to recover. Otherwise give up.
1423
1424 * aha1542.c (aha1542_reset): Try BUS DEVICE RESET, and then pass
1425 DID_RESET back up to the upper level code for all commands running
1426 on this target (even on different LUNs).
1427
1428Sat May 7 14:54:01 1994
1429
1430 * Linux 1.1.12 released.
1431
1432 * st.c, st.h: New version from Kai. Supports boot time
1433 specification of number of buffers.
1434
1435 * wd7000.[c,h]: Updated driver from John Boyd. Now supports
1436 more than one wd7000 board in machine at one time, among other things.
1437
1438Wed Apr 20 22:20:35 1994
1439
1440 * Linux 1.1.8 released.
1441
1442 * sd.c: Add a few type casts where scsi_malloc is called.
1443
1444Wed Apr 13 12:53:29 1994
1445
1446 * Linux 1.1.4 released.
1447
1448 * scsi.c: Clean up a few printks (use %p to print pointers).
1449
1450Wed Apr 13 11:33:02 1994
1451
1452 * Linux 1.1.3 released.
1453
1454 * fdomain.c: Update to version 5.16 (Handle different FIFO sizes
1455 better).
1456
1457Fri Apr 8 08:57:19 1994
1458
1459 * Linux 1.1.2 released.
1460
1461 * Throughout: SCSI portion of cluster diffs added.
1462
1463Tue Apr 5 07:41:50 1994
1464
1465 * Linux 1.1 development tree initiated.
1466
1467 * The linux 1.0 development tree is now effectively frozen except
1468 for obvious bugfixes.

1644
1645 * aha1542.c: Support for more than one 1542 in the machine
1646 at the same time. Make functions static that do not need
1647 visibility.
1648
1649 * aha1740.c: Set NEEDS_JUMPSTART flag in reset function, so we
1650 know to restart the command. Change prototype of aha1740_reset
1651 to take a command pointer.
1652
1653 * constants.c: Clean up a few things.
1654
1655 * fdomain.c: Update to version 5.6. Move snarf_region. Allow

1675 verify_area in GET_IDLUN ioctl. Add new ioctls for
1676 TAGGED_QUEUE_ENABLE, DISABLE. Only allow IOCTL_SEND_COMMAND by
1677 superuser.
1678
1679 * sd.c: Only pay attention to UNIT_ATTENTION for removable disks.
1680 Fix bug where sometimes portions of blocks would get lost
1681 resulting in processes hanging. Add messages when we spin up a
1682 disk, and fix a bug in the timing. Increase read-ahead for disks
1683 that are on a scatter-gather capable host adapter.
1684
1685 * seagate.c: Fix so that some parameters can be set from the lilo
1686 prompt. Supply jumpstart flag if we are resetting and need the
1687 command restarted. Fix so that we return 1 if we detect a card
1688 so that multiple card detection works correctly. Add yet another
1689 signature for FD cards (950). Add another signature for ST0x.
1690
1691 * sg.c, sg.h: New files from Lawrence Foard for generic scsi
1692 access.
1693
1694 * sr.c: Add type casts for (void*) so that we can do pointer
1695 arithmetic. Works with GCC without this, but it is not strictly
1696 correct. Same bugfix as was in sd.c. Increase read-ahead a la
1697 disk driver.
1698
1699 * sr_ioctl.c: Use scsi_malloc buffer instead of buffer from stack
1700 since we cannot guarantee that the stack is < 16Mb.
1701
1702 ultrastor.c: Update to support 24f properly (JFC's driver).
1703
1704 wd7000.c: Supply jumpstart flag for reset. Do not round up

1711 * Throughout: Use check_region/snarf_region for all low-level
1712 drivers.
1713
1714 * aha1542.c: Do hard reset instead of soft (some ethercard probes
1715 screw us up).
1716
1717 * scsi.c: Add new flag ASKED_FOR_SENSE so that we can tell if we are
1718 in a loop whereby the device returns null sense data.
1719
1720 * sd.c: Add code to spin up a drive if it is not already spinning.
1721 Do this one at a time to make it easier on power supplies.
1722

1743
1744 * fdomain.c: Update to version 3.18. Add new signature, register IRQ
1745 with irqaction. Use ID 7 for new board. Be more intelligent about
1746 obtaining the h/s/c numbers for biosparam.
1747
1748 * hosts.c: Do not depend upon Makefile generated count of the number
1749 of low-level host adapters.
1750
1751 * scsi.c: Use array for scsi_command_size instead of a function. Add
1752 Texel cdrom and Maxtor XT-4380S to blacklist. Allow compile time
1753 option for no-multi lun scan. Add semaphore for possible problems
1754 with handshaking, assume device is faulty until we know it not to be
1755 the case. Add DEBUG_INIT symbol to dump info as we scan for devices.
1756 Zero sense buffer so we can tell if we need to request it. When
1757 examining sense information, request sense if buffer is all zero.
1758 If RESET, request sense information to see what to do next.
1759
1760 * scsi_debug.c: Change some constants to use symbols like INT_MAX.
1761

1763 calls from kernel space.
1764
1765 * sd.c: Increase timeout to 300. Use functions in constants.h to
1766 display info. Use scsi_malloc buffer for READ_CAPACITY, since
1767 we cannot guarantee that a stack based buffer is < 16Mb.
1768
1769 * sd_ioctl.c: Add BLKFLSBUF ioctl.
1770
1771 * seagate.c: Add new compile time options for ARBITRATE,

1776
1777 * st.c: Support for variable block size.
1778
1779 * ultrastor.c: Do not use cache for tape drives. Set
1780 unchecked_isa_dma flag, even though this may not be needed (gets set
1781 later).
1782

1800 * scsi.c: Minor changes here and there with datatypes. Save use_sg
1801 when requesting sense information so that this can properly be
1802 restored if we retry the command. Set aside dma buffers assuming each
1803 block is 1 page, not 1Kb minix block.
1804
1805 * scsi_ioctl.c: Add a few type casts. Other minor changes.
1806
1807 * sd.c: Correctly free all scsi_malloc'd memory if we run out of
1808 dma_pool. Store blocksize information for each partition.

1828
1829 * sr.c: Increase timeout to 500 from 250. Add entry for sync in
1830 dispatch table (supply NULL). If we do not have a sectorsize,
1831 try to get it in the sd_open function. Add new function just to
1832 obtain sectorsize.
1833
1834 * sr.h: Add needs_sector_size semaphore.
1835
1836 * st.c: Add NULL for fsync in dispatch table.

1895 to lock door for devices that do not have lockable semaphore set.
1896
1897 * sd.c: Fix race condition for multiple disks. Use INIT_SCSI_REQUEST
1898 instead of INIT_REQUEST. Allow sector sizes of 1024 and 256. For
1899 removable disks that are not ready, mark them as having a media change
1900 (some drives do not report this later).
1901
1902 * seagate.c: Use volatile keyword for memory-mapped register pointers.
1903
1904 * sr.c: Fix race condition, a la sd.c. Increase the number of retries
1905 to 1. Use INIT_SCSI_REQUEST. Allow 512 byte sector sizes. Do a
1906 read_capacity when we init the device so we know the size and
1907 sectorsize.
1908
1909 * st.c: If ioctl not found in st.c, try scsi_ioctl for others.
1910
1911 * ultrastor.c: Do not truncate number of cylinders at 1024 for
1912 biosparam call.
1913
1914 * wd7000.c: Ditto.

1965
1966 * seagate.c: Add a few new signatures for FD cards. Another patch
1967 with SCint to fix race condition. Use recursion_depth to keep track
1968 of how many times we have been recursively called, and do not start
1969 another command unless we are on the outer level. Fixes bug
1970 with Syquest cartridge drives (used to crash kernel), because
1971 they do not disconnect with large data transfers.
1972

1999
2000 * st.c: Return ENODEV instead of ENXIO if no device. Init chrdev_fops
2001 sooner, so that it is always there even if no tapes.
2002
2003 * seagate.c (controller_type): New variable to keep track of ST0x or
2004 FD. Modify signatures list to indicate controller type, and init
