482 Patches from me (ERY) to finish support for low-level loadable scsi.
483 It now works, and is actually useful.
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.

502 Do not use waiting loops - use up and down mechanism as long
503 as current != task[0].
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).
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.
513 * scsi_module.c: Fix include.
515 * sd.c: Declare detach function. Increment/decrement module usage
516 count as required. Fix init functions to allow loaded devices.

683 * Linux 1.1.71 released.
685 * sg.c: Clear buff field when not in use. Only call scsi_free if
688 * scsi.h: Call wake_up(&wait_for_request) when done with a
691 * scsi.c (scsi_times_out): Pass pid down so that we can protect
692 against race conditions.
694 * scsi.c (scsi_abort): Zero timeout field if we get the
695 NOT_RUNNING message back from low-level driver.
698 * scsi.c (scsi_done): Restore cmd_len, use_sg here.
700 * scsi.c (request_sense): Not here.
702 * hosts.h: Add new forbidden_addr, forbidden_size fields. Who
703 added these and why????
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.
710 * buslogic.c: Set forbidden_addr stuff if using a buggy board.
712 * aha1740.c: Test for NULL pointer in SCtmp. This should not
713 occur, but a nice message is better than a kernel segfault.

727 * u14-34f.h: Non-functional change. [Dario].
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).

760 hog memory). Use other patches which got lost from 1.1.68.
762 * aha1542.c: Spelling.

774 * Throughout: Change COMMAND_SIZE() to use SCpnt->cmd_len.
776 * Throughout: Change info() low level function to take a Scsi_Host
777 pointer. This way the info function can return specific

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
814 * hosts.h: Add usage_count to Scsi_Host_Template.
816 * hosts.h: Add n_io_port to Scsi_Host (used when releasing module).
818 * hosts.c: Initialize block field.
820 * in2000.c: Remove "static" declarations from exported functions.
822 * in2000.h: Likewise.

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.
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
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.
838 * sd.c, sr.c: Clear cmd_len field prior to each command we
841 * sd.h: Add "has_part_table" bit to rscsi_disks.
843 * sg.[c,h]: Add support for vendor specific 12 byte commands (i.e.
844 override command length in COMMAND_SIZE).
846 * sr.c: Bugfix from Gerd in photocd code.
848 * sr.c: Bugfix in get_sectorsize - always use scsi_malloc buffer -
849 we cannot guarantee that the stack is < 16Mb.

1184 (scsi_register_device): New function to insert into this list.
1185 (scsi_init): Call scsi_register_device for each of the known high
1188 hosts.h: Add prototype for linked list header. Add structure
1189 definition for device template structure which defines the linked
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
1198 scsi.h: Add new field "attached" to scsi_device - count of number
1199 of high level devices attached.
1201 sd.c, sr.c, sg.c, st.c: Adjust init/attach functions to use new
1204 Sat Jul 23 13:03:17 1994 Eric Youngdale (eric@esp22)

1246 the task state before sleeping.
1248 Sat Jul 9 15:01:03 1994 Eric Youngdale (eric@esp22)
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.
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
1258 * Linux 1.1.28 released.
1260 * scsi.c, scsi.h (allocate_device, request_queueable): Change
1261 argument from index into scsi_devices to a pointer to the
1264 * Throughout: Change all calls to allocate_device,
1265 request_queueable to use new calling sequence.
1267 * Throughout: Use SCpnt->device instead of
1268 scsi_devices[SCpnt->index]. Ugh - the pointer was there all along
1269 - much cleaner this way.
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.
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.
1279 * scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd
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.
1287 * scsi.c (scan_scsis): Change to only scan one host.
1288 (scsi_dev_init): Loop over all detected hosts, and scan them.
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.
1293 * hosts.h: Change Scsi_Host_Template struct to include "next" and
1294 "release" functions. Initialize to NULL in all low level
1297 * hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked
1298 list scsi_hosts, linked together with the new "next" field.

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.
1316 * sd_ioctl.c: Pass pointer to rscsi_disks element instead of index
1319 * sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk.
1321 * scsi.c: Remove redundant Maxtor XT8760S from blacklist.

1329 * Linux 1.1.20 released.
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
1335 * ultrastor.c: Changes from Caleb Epstein for 24f cards. Support
1338 * ultrastor.c: Changes from me - use scsi_register to register
1339 host. Add some consistency checking,

1343 * Linux 1.1.19 released.
1345 * scsi.h: Add new return code for reset() function:

1351 * aha1542.c: If the command responsible for the reset is not
1352 pending, return SCSI_RESET_PUNT.
1354 * aha1740.c, buslogic.c, wd7000.c, ultrastor.c: Return
1355 SCSI_RESET_PUNT instead of SCSI_RESET_SNOOZE.
1357 Tue May 31 19:36:01 1994 Eric Youngdale (eric@esp22)
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.
1365 Changes based upon patches in Yggdrasil distribution.
1367 * sg.c, sg.h: Return sense data to user.
1369 * aha1542.c, aha1740.c, buslogic.c: Do not panic if
1370 sense buffer is wrong size.
1372 * hosts.c: Test for ultrastor card before any of the others.
1374 * scsi.c: Allow boot-time option for max_scsi_luns=? so that
1375 buggy firmware has an easy work-around.
1377 Sun May 15 20:24:34 1994 Eric Youngdale (eric@esp22)
1379 * Linux 1.1.15 released.
1381 Post-codefreeze thaw...
1383 * buslogic.[c,h]: New driver from David Gentzel.
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
1391 * sd.c: Use this field instead of heuristic.
1393 * All host adapter include files: Add appropriate initializer for
1394 use_clustering field.
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
1401 * scsi.c: Act based upon return codes from abort/reset functions.
1403 * All host adapter abort/reset functions: Return new return code.
1405 * Add code in scsi.c to help debug timeouts. Use #define
1406 DEBUG_TIMEOUT to enable this.
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).
1414 * constants.c: Fix some things to eliminate warnings. Add some
1415 sense descriptions that were omitted before.
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.
1421 * aha1542.c (aha1542_abort): Look for lost interrupts, OGMB still
1422 full, and attempt to recover. Otherwise give up.
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).
1428 Sat May 7 14:54:01 1994
1430 * Linux 1.1.12 released.
1432 * st.c, st.h: New version from Kai. Supports boot time

1457 Fri Apr 8 08:57:19 1994
1459 * Linux 1.1.2 released.
1461 * Throughout: SCSI portion of cluster diffs added.
1463 Tue Apr 5 07:41:50 1994
1465 * Linux 1.1 development tree initiated.
1467 * The linux 1.0 development tree is now effectively frozen except
1468 for obvious bugfixes.

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.
1653 * constants.c: Clean up a few things.
1655 * fdomain.c: Update to version 5.6. Move snarf_region. Allow

1669 * scsi.h: Add constants for tagged queueing.
1671 * Throughout: Use constants from major.h instead of hardcoded
1672 numbers for major numbers.
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
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.
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.
1691 * sg.c, sg.h: New files from Lawrence Foard for generic scsi
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
1699 * sr_ioctl.c: Use scsi_malloc buffer instead of buffer from stack
1700 since we cannot guarantee that the stack is < 16Mb.
1702 ultrastor.c: Update to support 24f properly (JFC's driver).
1704 wd7000.c: Supply jumpstart flag for reset. Do not round up

1737 just generate the list of .o files.
1739 * aha1542.c: Replace 16 with sizeof(SCpnt->sense_buffer). Add tests
1740 for addresses > 16Mb, panic if we find one.
1742 * aha1740.c: Ditto with sizeof().
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.
1748 * hosts.c: Do not depend upon Makefile generated count of the number
1749 of low-level host adapters.
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.
1760 * scsi_debug.c: Change some constants to use symbols like INT_MAX.
1762 * scsi_ioctl.c (kernel_scsi_ioctl): New function -for making ioctl
1763 calls from kernel space.
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.
1769 * sd_ioctl.c: Add BLKFLSBUF ioctl.
1771 * seagate.c: Add new compile time options for ARBITRATE,
1772 SLOW_HANDSHAKE, and SLOW_RATE. Update assembly loops for transferring

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.
1805 * scsi_ioctl.c: Add a few type casts. Other minor changes.
1807 * sd.c: Correctly free all scsi_malloc'd memory if we run out of
1808 dma_pool. Store blocksize information for each partition.

1889 * scsi.h: Define COMMAND_SIZE. Define a SCSI specific version of
1890 INIT_REQUEST that can run with interrupts off.
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.
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).
1902 * seagate.c: Use volatile keyword for memory-mapped register pointers.
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
1909 * st.c: If ioctl not found in st.c, try scsi_ioctl for others.

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.
1973 Tue Jan 12 14:33:36 1993
1977 * fdomain.c: Update to version 3.3 (a few new signatures).

1986 * st.c: Changes from Kai.
1988 Wed Dec 30 20:03:47 1992
1992 * scsi.c: Blacklist back in. Remove Newbury drive as other bugfix
1993 eliminates need for it here.
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.
1998 * sr.c: Same as above for sd.c.
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.
