 125Wed Apr 12 15:25:52 1995  Eric Youngdale  (eric@andante)
 126
 127        * Linux 1.2.5 released.
 128
 129        * buslogic.c: Update to version 1.15 (From Leonard N. Zubkoff).
 130        Fixed interrupt routine to avoid races when handling multiple
 131        complete commands per interrupt.  Seems to come up with faster
 132        cards.
 133
 134        * eata_dma.c: Update to 2.3.5r. Modularize. Improved error handling
 135        throughout and fixed bug interrupt routine which resulted in shifted
 136        status bytes. Added blink LED state checks for ISA and EISA HBAs.
 137        Memory management bug seems to have disappeared ==> increasing
 138        C_P_L_CURRENT_MAX to 16 for now. Decreasing C_P_L_DIV to 3 for
 139        performance reasons.
 140
 141        * scsi.c: If we get a FMK, EOM, or ILI when attempting to scan
 142        the bus, assume that it was just noise on the bus, and ignore
 143        the device.
 144
 145        * scsi.h: Update and add a bunch of missing commands which we
 146        were never using.
 147
 148        * sd.c: Use restore_flags in do_sd_request - this may result in
 149        latency conditions, but it gets rid of races and crashes.
 150        Do not save flags again when searching for a second command to
 151        queue.
 152
 153        * st.c: Use bytes, not STP->buffer->buffer_size when reading
 154        from tape.
 155
 156

 178
 179        * scsi.c: Detect as NEC (for photo-cd purposes) for the 84
 180        and 25 models as "NEC_OLDCDR".
 181
 182        * scsi.h: Add define for NEC_OLDCDR
 183

 219          NULL pointer panic on odd UDCs fixed, two bugs in diagnostic output
 220          fixed, should initialize correctly if left running, now loadable,
 221          new memory allocation, extraneous diagnostic output suppressed,
 222          splx() replaced with save/restore flags. [ Drew ]

 233        Restore interrupts after unregistering a host.
 234
 235        * sd.c: Use sti instead of restore flags - causes latency problems.

 252        Continuing modularization. Less crashes because of the bug in the
 253        memory management ==> increase C_P_L_CURRENT_MAX to 10
 254        and decrease C_P_L_DIV to 4.
 255
 256        * hosts.c: If we remove last host registered, reuse host number.

 418        * buslogic.c: Likewise.
 419
 420        * eata_dma.c: Use min of 2 cmd_per_lun for OCS_enabled boards.
 421
 422        * scsi.c: Make RECOVERED_ERROR a SUGGEST_IS_OK.
 423
 424        * sd.c: Fail if we are opening a non-existent partition.
 425
 426        * sr.c: Bump SR_TIMEOUT to 15000.
 427        Do not probe for media size at boot time(hard on changers).
 428        Flag device as needing sector size instead.
 429
 430        * sr_ioctl.c: Remove CDROMMULTISESSION_SYS ioctl.
 431
 432        * ultrastor.c: Fix bug in call to ultrastor_interrupt (wrong #args).
 433
 434Mon Jan 16 07:18:23 1995  Eric Youngdale  (eric@andante)
 435
 436        * Linux 1.1.82 released.
 437
 438        Throughout.
 439        - Change all interrupt handlers to accept new calling convention.
 440        In particular, we now receive the irq number as one of the arguments.
 441
 442        * More minor spelling corrections in some of the new files.
 443
 444        * aha1542.c, buslogic.c: Clean up interrupt handler a little now
 445        that we receive the irq as an arg.
 446
 447        * aha274x.c: s/snarf_region/request_region/
 448
 449        * eata.c: Update to version 1.12.   Fix some comments and display a
 450        message if we cannot reserve the port addresses.
 451
 452        * u14-34f.c: Update to version 1.13.   Fix some comments and display a
 453        message if we cannot reserve the port addresses.
 454
 455        * eata_dma.c: Define get_board_data function (send INQUIRY command).
 456        Use to improve detection of variants of different DPT boards.  Change
 457        version subnumber to "0g".
 458
 459        * fdomain.c:  Update to version 5.26.  Improve detection of some boards
 460        repackaged by IBM.
 461
 462        * scsi.c (scsi_register_host): Change "name" to const char *.
 463
 464        * sr.c: Fix problem in set mode command for Toshiba drives.
 465
 466        * sr.c: Fix typo from patch 81.
 467
 468Fri Jan 13 12:54:46 1995  Eric Youngdale  (eric@andante)
 469
 470        * Linux 1.1.81 released.  Codefreeze for 1.2 release announced.
 471
 472        Big changes here.
 473
 474        * eata_dma.*: New files from Michael Neuffer.
 475        (neuffer@goofy.zdv.uni-mainz.de).  Should support
 476        all eata/dpt cards.
 477
 478        * hosts.c, Makefile: Add eata_dma.
 479
 480        * README.st: Document MTEOM.
 481
 482        Patches from me (ERY) to finish support for low-level loadable scsi.
 483        It now works, and is actually useful.
 484
 485        * Throughout - add new argument to scsi_init_malloc that takes an
 486        additional parameter.  This is used as a priority to kmalloc,
 487        and you can specify the GFP_DMA flag if you need DMA-able memory.
 488
 489        * Makefile: For source files that are loadable, always add name
 490        to SCSI_SRCS.  Fill in modules: target.
 491
 492        * hosts.c:  Change next_host to next_scsi_host, and make global.
 493        Print hosts after we have identified all of them.  Use info()
 494        function if present, otherwise use name field.
 495
 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.
 527
 528Tue Jan 10 10:09:58 1995  Eric Youngdale  (eric@andante)
 529
 530        * Linux 1.1.79 released.
 531
 532        Patch from some undetermined individual who needs to get a life :-).
 533
 534        * sr.c: Attacked by spelling bee...
 535
 536        Patches from Gerd Knorr:
 537
 538        * sr.c: make printk messages for photoCD a little more informative.
 539
 540        * sr_ioctl.c: Fix CDROMMULTISESSION_SYS ioctl.
 541
 542Mon Jan  9 10:01:37 1995  Eric Youngdale  (eric@andante)
 543
 544        * Linux 1.1.78 released.
 545
 546        * Makefile: Add empty modules: target.
 547
 548        * Wheee.  Now change register_iomem to request_region.
 549
 550        * in2000.c: Bugfix - apparently this is the fix that we have
 551        all been waiting for.  It fixes a problem whereby the driver
 552        is not stable under heavy load.  Race condition and all that.
 553        Patch from Peter Lu.
 554
 555Wed Jan  4 21:17:40 1995  Eric Youngdale  (eric@andante)
 556
 557        * Linux 1.1.77 released.
 558
 559        * 53c7,8xx.c: Fix from Linus - emulate splx.
 560
 561        Throughout:
 562
 563                Change "snarf_region" with "register_iomem".
 564
 565        * scsi_module.c: New file.  Contains support for low-level loadable
 566          scsi drivers. [ERY].
 567
 568        * sd.c: More s/int/long/ changes.
 569
 570        * seagate.c: Explicitly include linux/config.h
 571
 572        * sg.c: Increment/decrement module usage count on open/close.
 573
 574        * sg.c: Be a bit more careful about the user not supplying enough
 575          information for a valid command.  Pass correct size down to
 576          scsi_do_cmd.
 577
 578        * sr.c:  More changes for Photo-CD.  This apparently breaks NEC drives.
 579
 580        * sr_ioctl.c:  Support CDROMMULTISESSION ioctl.
 581
 582
 583Sun Jan  1 19:55:21 1995  Eric Youngdale  (eric@andante)
 584
 585        * Linux 1.1.76 released.
 586
 587        * constants.c: Add type cast in switch statement.
 588
 589        * scsi.c (scsi_free): Change datatype of "offset" to long.
 590          (scsi_malloc): Change a few more variables to long.  Who
 591          did this and why was it important?  64 bit machines?
 592
 593
 594        Lots of changes to use save_state/restore_state instead of cli/sti.
 595        Files changed include:
 596
 597        * aha1542.c:
 598        * aha1740.c:
 599        * buslogic.c:
 600        * in2000.c:
 601        * scsi.c:
 602        * scsi_debug.c:
 603        * sd.c:
 604        * sr.c:
 605        * st.c:

 616
 617        * sd.c: Add support for sd_hardsizes (hard sector sizes).
 618
 619        * ultrastor.c: Use save_flags/restore_flags instead of cli/sti.
 620
 621Fri Dec 23 13:36:25 1994  Eric Youngdale  (eric@andante)
 622
 623        * Linux 1.1.74 released.

 625        * README.st: Update from Kai Makisara.
 626
 627        * eata.c: New version from Dario - version 1.11.
 628          use scsicam bios_param routine.  Add support for 2011
 629          and 2021 boards.
 630
 631        * hosts.c: Add support for blocking.  Linked list automatically
 632          generated when shpnt->block is set.
 633
 634        * scsi.c: Add sankyo & HP scanjet to blacklist.  Add support for
 635          kicking things loose when we deadlock.
 636
 637        * scsi.c: Recognize scanners and processors in scan_scsis.
 638
 639        * scsi_ioctl.h: Increase timeout to 9 seconds.

 646
 647        * Linux 1.1.73 released.
 648
 649        * buslogic.c: Update from Dave Gentzel.  Version 1.14.
 650          Add module related stuff.   More fault tolerant if out of
 651          DMA memory.
 652
 653        * fdomain.c: New version from Rik Faith - version 5.22.  Add support
 654          for ISA-200S SCSI adapter.
 655
 656        * hosts.c: Spelling.
 657
 658        * qlogic.c: Update to version 0.38a.  Add more support for PCMCIA.
 659
 660        * scsi.c: Mask device type with 0x1f during scan_scsis.
 661          Add support for deadlocking, err, make that getting out of
 662          deadlock situations that are created when we allow the user
 663          to limit requests to one host adapter at a time.
 664
 665        * scsi.c: Bugfix - pass pid, not SCpnt as second arg to
 666          scsi_times_out.
 667
 668        * scsi.c: Restore interrupt state to previous value instead of using
 669          cli/sti pairs.
 670
 671        * scsi.c: Add a bunch of module stuff (all commented out for now).
 672
 673        * scsi.c: Clean up scsi_dump_status.
 674
 675Tue Dec  6 12:34:20 1994  Eric Youngdale  (eric@andante)
 676
 677        * Linux 1.1.72 released.
 678
 679        * sg.c: Bugfix - always use sg_free, since we might have big buff.
 680
 681Fri Dec  2 11:24:53 1994  Eric Youngdale  (eric@andante)
 682
 683        * Linux 1.1.71 released.
 684
 685        * sg.c: Clear buff field when not in use.  Only call scsi_free if
 686        non-null.
 687
 688        * scsi.h: Call wake_up(&wait_for_request) when done with a
 689        command.
 690
 691        * scsi.c (scsi_times_out): Pass pid down so that we can protect
 692        against race conditions.
 693
 694        * scsi.c (scsi_abort): Zero timeout field if we get the
 695        NOT_RUNNING message back from low-level driver.
 696
 697
 698        * scsi.c (scsi_done): Restore cmd_len, use_sg here.
 699
 700        * scsi.c (request_sense): Not here.
 701
 702        * hosts.h: Add new forbidden_addr, forbidden_size fields.  Who
 703        added these and why????
 704
 705        * hosts.c (scsi_mem_init): Mark pages as reserved if they fall in
 706        the forbidden regions.  I am not sure - I think this is so that
 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.
 714
 715        * 53c7,8xx.c: Add new PCI chip ID for 815.
 716
 717Fri Dec  2 11:24:53 1994  Eric Youngdale  (eric@andante)
 718
 719        * Linux 1.1.70 released.

 722
 723Tue Nov 29 18:48:42 1994  Eric Youngdale  (eric@andante)
 724
 725        * Linux 1.1.69 released.
 726
 727        * u14-34f.h: Non-functional change.  [Dario].
 728
 729        * u14-34f.c: Use block field in Scsi_Host to prevent commands from
 730        being queued to more than one host at the same time (used when
 731        motherboard does not deal with multiple bus-masters very well).
 732        Only when SINGLE_HOST_OPERATIONS is defined.
 733        Use new cmd_per_lun field.  [Dario]
 734
 735        * eata.c: Likewise.
 736
 737        * st.c: More changes from Kai.  Add ready flag to indicate drive
 738        status.
 739
 740        * README.st: Document this.
 741
 742        * sr.c: Bugfix (do not subtract CD_BLOCK_OFFSET) for photo-cd
 743        code.
 744
 745        * sg.c: Bugfix - fix problem where opcode is not correctly set up.
 746
 747        * seagate.[c,h]: Use #defines to set driver name.
 748
 749        * scsi_ioctl.c: Zero buffer before executing command.
 750
 751        * scsi.c: Use new cmd_per_lun field in Scsi_Hosts as appropriate.
 752        Add Sony CDU55S to blacklist.
 753
 754        * hosts.h: Add new cmd_per_lun field to Scsi_Hosts.
 755
 756        * hosts.c: Initialize cmd_per_lun in Scsi_Hosts from template.
 757
 758        * buslogic.c: Use cmd_per_lun field - initialize to different
 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
 764Tue Nov 29 15:43:50 1994  Eric Youngdale  (eric@andante.aib.com)
 765
 766        * Linux 1.1.68 released.
 767
 768        Add support for 12 byte vendor specific commands in scsi-generics,
 769        more (i.e. the last mandatory) low-level changes to support
 770        loadable modules, plus a few other changes people have requested
 771        lately.  Changes by me (ERY) unless otherwise noted.  Spelling
 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
 778        information about the host in question, if desired.
 779
 780        * All low-level drivers: Add NULL in initializer for the
 781        usage_count field added to Scsi_Host_Template.
 782
 783        * aha152x.[c,h]: Remove redundant info() function.
 784
 785        * aha1542.[c,h]: Likewise.
 786
 787        * aha1740.[c,h]: Likewise.
 788

 798
 799        * u14-34f.[c,h]: Likewise.
 800
 801        * ultrastor.[c,h]: Likewise.
 802
 803        * wd7000.[c,h]: Likewise.
 804
 805        * aha1542.c: Add support for command line options with lilo to set
 806        DMA parameters, I/O port.  From Matt Aarnio.
 807
 808        * buslogic.[c,h]: New version (1.13) from Dave Gentzel.
 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).
 817
 818        * hosts.c: Initialize block field.
 819
 820        * in2000.c: Remove "static" declarations from exported functions.
 821
 822        * in2000.h: Likewise.
 823
 824        * scsi.c: Correctly set cmd_len field as required.  Save and
 825        change setting when doing a request_sense, restore when done.
 826        Move abort timeout message.  Fix panic in request_queueable to
 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.

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

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

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

1451
1452        * Linux 1.1.3 released.

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.

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

1664
1665        * scsi.c:  Add scsi_device_types array, if NEEDS_JUMPSTART is set
1666        after a low-level reset, start the command again.  Sort blacklist,
1667        and add Maxtor MXT-1240S, XT-4170S, NEC CDROM 84, Seagate ST157N.
1668
1669        * scsi.h: Add constants for tagged queueing.

1672        numbers for major numbers.
1673
1674        * scsi_ioctl.c: Fix bug in buffer length in ioctl_command.  Use
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
1705        number of cylinders in biosparam function.
1706

1708
1709    * 0.99pl13 released.
1710
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
1723    * sd_ioctl.c: Use sync_dev instead of fsync_dev in BLKFLSBUF ioctl.
1724
1725    * seagate.c: Switch around DATA/CONTROL lines.
1726
1727    * st.c: Change sense to unsigned.
1728

1730
1731    * 0.99pl12 released.
1732
1733    * constants.c, constants.h: New files with ascii descriptions of
1734    various conditions.
1735
1736    * Makefile: Do not try to count the number of low-level drivers,
1737    just generate the list of .o files.
1738
1739    * aha1542.c: Replace 16 with sizeof(SCpnt->sense_buffer).  Add tests
1740    for addresses > 16Mb, panic if we find one.
1741
1742    * aha1740.c: Ditto with sizeof().
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
1762    * scsi_ioctl.c (kernel_scsi_ioctl): New function -for making ioctl
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,
1772    SLOW_HANDSHAKE, and SLOW_RATE.  Update assembly loops for transferring
1773    data.  Use kernel_scsi_ioctl to request mode page with geometry.
1774
1775    * sr.c: Use functions in constants.c to display messages.
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
1783Sat Jul 17 18:32:44 1993
1784
1785    * 0.99pl11 released.  C++ compilable.
1786
1787    * Throughout: Add type casts all over the place, and use "ip" instead
1788    of "info" in the various biosparam functions.
1789
1790    * Makefile: Compile seagate.c with C++ compiler.
1791
1792    * aha1542.c: Always set ccb pointer as this gets trashed somehow on
1793    some systems.  Add a few type casts.  Update biosparam function a little.
1794
1795    * aha1740.c: Add a few type casts.
1796
1797    * fdomain.c: Update to version 3.17 from 3.6.  Now works with
1798    TMC-18C50.
1799
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.
1809
1810    * seagate.c: Minor cleanups here and there.
1811
1812    * sr.c: Set up blocksize array for all discs.  Fix bug in freeing
1813    buffers if we run out of dma pool.

1822
1823    * scsi.c: First attempt to fix problem with old_use_sg.  Change
1824    NOT_READY to a SUGGEST_ABORT.  Fix timeout race where time might
1825    get decremented past zero.
1826
1827    * sd.c: Add block_fsync function to dispatch table.
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.
1837
1838    * wd7000.c: Allow another condition for power on that are normal
1839    and do not require a panic.

1848    Do not panic for unsupported message bytes.
1849
1850    * scsi.h: Allocate 12 bytes instead of 10 for commands.  Add
1851    transfersize and underflow fields.
1852
1853    * scsi_ioctl.c: Further bugfix to ioctl_probe.
1854
1855    * sd.c: Use long instead of int for last parameter in sd_ioctl.
1856    Initialize transfersize and underflow fields.
1857
1858    * sd_ioctl.c: Ditto for sd_ioctl(,,,,);
1859
1860    * seagate.c: New version from Drew.  Includes new signatures for FD
1861    cards.  Support for 0ws jumper. Correctly initialize
1862    scsi_hosts[hostnum].this_id.  Improved handing of
1863    disconnect/reconnect, and support command linking.  Use
1864    transfersize and underflow fields.  Support scatter-gather.
1865
1866    * sr.c, sr_ioctl.c: Use long instead of int for last parameter in sr_ioctl.

1885    media removal prevented.  Add another signature for flopticals.
1886    (allocate_device): Fix race condition.  Allow more space in dma pool
1887    for blocksizes of up to 4Kb.
1888
1889    * scsi.h: Define COMMAND_SIZE.  Define a SCSI specific version of
1890    INIT_REQUEST that can run with interrupts off.
1891
1892    * scsi_ioctl.c: Make ioctl_probe function more idiot-proof.  If
1893    a removable device says ILLEGAL REQUEST to a door-locking command,
1894    clear lockable flag.  Add SCSI_IOCTL_GET_IDLUN ioctl.  Do not attempt
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.
1915    Throughout: Use COMMAND_SIZE macro to determine length of scsi
1916    command.
1917
1918
1919
1920Sat Mar 13 17:31:29 1993
1921
1922    * 0.99pl7 released.
1923
1924    Throughout: Improve punctuation in some messages, and use new
1925    verify_area syntax.
1926
1927    * aha1542.c: Handle unexpected interrupts better.
1928
1929    * scsi.c: Ditto.  Handle reset conditions a bit better, asking for
1930    sense information and retrying if required.
1931
1932    * scsi_ioctl.c: Allow for 12 byte scsi commands.
1933
1934    * ultrastor.c: Update to use scatter-gather.

1944
1945    * sr.c: Ditto.
1946
1947    * st.c: Use register_chrdev function.
1948

1961
1962    * 0.99pl4 released.
1963
1964    * scsi.c: Ignore leading spaces when looking for blacklisted devices.
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
1973Tue Jan 12 14:33:36 1993
1974
1975    * 0.99pl3 released.

1989
1990    * 0.99pl2 released.
1991
1992    * scsi.c: Blacklist back in.  Remove Newbury drive as other bugfix
1993    eliminates need for it here.
1994
1995    * sd.c: Return ENODEV instead of EACCES if no such device available.
1996    (sd_init) Init blkdev_fops earlier so that sd_open is available sooner.
1997
1998    * sr.c: Same as above for sd.c.
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
2005    controller_type once we find a match.
2006
2007    * wd7000.c (wd7000_set_sync): Remove redundant function.
2008

2017
2018    * st.c: Patches from Kai - change timeout values, improve end of tape
2019    handling.
2020
2021Sun Dec 13 18:15:23 1992
