+Fri Jan 13 12:54:46 1995  Eric Youngdale  (eric@andante)
+
+	* Linux 1.1.81 released.  Codefreeze for 1.2 release announced.
+
+	Big changes here.
+
+	* eata_dma.*: New files from Michael Neuffer.
+	(neuffer@goofy.zdv.uni-mainz.de).  Should support
+	all eata/dpt cards.
+
+	* hosts.c, Makefile: Add eata_dma.
+
+	* README.st: Document MTEOM.
+
+	Patches from me (ERY) to finish support for low-level loadable scsi.
+	It now works, and is actually useful.
+
+	* Throughout - add new argument to scsi_init_malloc that takes an
+	additional parameter.  This is used as a priority to kmalloc,
+	and you can specify the GFP_DMA flag if you need DMA-able memory.
+
+	* Makefile: For source files that are loadable, always add name
+	to SCSI_SRCS.  Fill in modules: target.
+
+	* hosts.c:  Change next_host to next_scsi_host, and make global.
+	Print hosts after we have identified all of them.  Use info()
+	function if present, otherwise use name field.

+	Define number of device slots to allow for loadable devices.
+	Define tags to tell scsi module code what type of module we
+	are loading.

+	Do not use waiting loops - use up and down mechanism as long
+	as current != task[0].
+
+	* scsi.c(scan_scsis): Do not use stack variables for I/O - this
+	could be > 16Mb if we are loading a module at runtime (i.e. use
+	scsi_init_malloc to get some memory we know will be safe).
+
+	* scsi.c: Change dma freelist to be a set of pages.  This allows
+	us to dynamically adjust the size of the list by adding more pages
+	to the pagelist.  Fix scsi_malloc and scsi_free accordingly.
+
+	* scsi_module.c: Fix include.
+
+	* sd.c: Declare detach function.  Increment/decrement module usage
+	count as required.  Fix init functions to allow loaded devices.
+	Revalidate all new disks so we get the partition tables.  Define
+	detach function.
+
+	* sr.c: Likewise.
+
+	* sg.c: Declare detach function.  Allow attachment of devices on
+	loaded drivers.
+
+	* st.c: Declare detach function.  Increment/decrement module usage
+	count as required.

+
+	* Makefile: Add empty modules: target.
+
+	* Wheee.  Now change register_iomem to request_region.
+
+	* in2000.c: Bugfix - apparently this is the fix that we have
+	all been waiting for.  It fixes a problem whereby the driver
+	is not stable under heavy load.  Race condition and all that.
+	Patch from Peter Lu.
+
+Wed Jan  4 21:17:40 1995  Eric Youngdale  (eric@andante)
+
+	* Linux 1.1.77 released.

+	  scsi_do_cmd.
+
+	* sr.c:  More changes for Photo-CD.  This apparently breaks NEC drives.
+
+	* sr_ioctl.c:  Support CDROMMULTISESSION ioctl.
+
+
+Sun Jan  1 19:55:21 1995  Eric Youngdale  (eric@andante)

+
+	* constants.c: Add type cast in switch statement.
+
+	* scsi.c (scsi_free): Change datatype of "offset" to long.

+
+
+	Lots of changes to use save_state/restore_state instead of cli/sti.
+	Files changed include:
+
+	* aha1542.c:
+	* aha1740.c:
+	* buslogic.c:
+	* in2000.c:

+
+	* u14-34f.c: Use block field in Scsi_Host to prevent commands from
+	being queued to more than one host at the same time (used when

+	hog memory).  Use other patches which got lost from 1.1.68.
+
+	* aha1542.c: Spelling.
+
+Tue Nov 29 15:43:50 1994  Eric Youngdale  (eric@andante.aib.com)
+
+	* Linux 1.1.68 released.

+	Add support for 12 byte vendor specific commands in scsi-generics,
+	more (i.e. the last mandatory) low-level changes to support
+	loadable modules, plus a few other changes people have requested
+	lately.  Changes by me (ERY) unless otherwise noted.  Spelling
+	changes appear from some unknown corner of the universe.
+
+	* Throughout: Change COMMAND_SIZE() to use SCpnt->cmd_len.
+
+	* Throughout: Change info() low level function to take a Scsi_Host
+	pointer.  This way the info function can return specific
+	information about the host in question, if desired.
+
+	* All low-level drivers: Add NULL in initializer for the
+	usage_count field added to Scsi_Host_Template.
+
+	* aha152x.[c,h]: Remove redundant info() function.

+	* buslogic.[c,h]: New version (1.13) from Dave Gentzel.
+
+	* hosts.h: Add new field to Scsi_Hosts "block" to allow blocking
+	all I/O to certain other cards.  Helps prevent problems with some
+	ISA motherboards.
+
+	* hosts.h: Add usage_count to Scsi_Host_Template.
+
+	* hosts.h: Add n_io_port to Scsi_Host (used when releasing module).

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

+	of high level devices attached.
+
+	sd.c, sr.c, sg.c, st.c: Adjust init/attach functions to use new

+	we want to use linked lists instead of arrays because it is easier
+	to dynamically add and remove things this way.
+
+	Quite a bit more work is needed before loadable modules are
+	possible (and usable) with scsi, but this is most of the grunge
+	work.
+
+	* Linux 1.1.28 released.
+
+	* scsi.c, scsi.h (allocate_device, request_queueable): Change
+	argument from index into scsi_devices to a pointer to the
+	Scsi_Device struct.
+
+	* Throughout: Change all calls to allocate_device,
+	request_queueable to use new calling sequence.
+
+	* Throughout: Use SCpnt->device instead of
+	scsi_devices[SCpnt->index].  Ugh - the pointer was there all along
+	- much cleaner this way.
+
+	* scsi.c (scsi_init_malloc, scsi_free_malloc): New functions -
+	allow us to pretend that we have a working malloc when we
+	initialize.  Use this instead of passing memory_start, memory_end
+	around all over the place.
+
+	* scsi.h, st.c, sr.c, sd.c, sg.c: Change *_init1 functions to use
+	scsi_init_malloc, remove all arguments, no return value.
+
+	* scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd
+	structs.
+
+	* scsi.c (scsi_dev_init): Set up for scsi_init_malloc.
+	(scan_scsis): Get SDpnt from scsi_init_malloc, and refresh
+	when we discover a device.  Free pointer before returning.
+	Change scsi_devices into a linked list.
+
+	* scsi.c (scan_scsis): Change to only scan one host.
+	(scsi_dev_init): Loop over all detected hosts, and scan them.
+
+	* hosts.c  (scsi_init_free): Change so that  number of extra bytes
+	is stored in struct, and we do not have to pass it each time.
+
+	* hosts.h: Change Scsi_Host_Template struct to include "next" and
+	"release" functions.  Initialize to NULL in all low level
+	adapters.
+
+	* hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked
+	list scsi_hosts, linked together with the new "next" field.
+
+Wed Jul  6 05:45:02 1994  Eric Youngdale  (eric@esp22)
+
+	* Linux 1.1.25 released.
+
+	* aha152x.c: Changes from Juergen - cleanups and updates.
+
+	* sd.c, sr.c: Use new check_media_change and revalidate
+	file_operations fields.
+
+	* st.c, st.h: Add changes from Kai Makisara, dated Jun 22.
+
+	* hosts.h: Change SG_ALL back to 0xff.  Apparently soft error
+	in /dev/brain resulted in having this bumped up.
+	Change first parameter in bios_param function to be Disk * instead
+	of index into rscsi_disks.
+
+	* sd_ioctl.c: Pass pointer to rscsi_disks element instead of index
+	to array.
+
+	* sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk.
+
+	* scsi.c: Remove redundant Maxtor XT8760S from blacklist.
+	In scsi_reset, add printk when DEBUG defined.
+
+	* All low level drivers: Modify definitions of bios_param in
+	appropriate way.
+
+Thu Jun 16 10:31:59 1994  Eric Youngdale  (eric@esp22)
+
+	* Linux 1.1.20 released.
+
+	* scsi_ioctl.c: Only pass down the actual number of characters
+	required to scsi_do_cmd, not the one rounded up to a even number
+	of sectors.
+
+	* ultrastor.c: Changes from Caleb Epstein for 24f cards.  Support
+	larger SG lists.
+
+	* ultrastor.c: Changes from me - use scsi_register to register
+	host.  Add some consistency checking,
+
+Wed Jun  1 21:12:13 1994  Eric Youngdale  (eric@esp22)
+
+	* Linux 1.1.19 released.
+
+	* scsi.h: Add new return code for reset() function:
+	SCSI_RESET_PUNT.
+
+	* scsi.c: Make SCSI_RESET_PUNT the same as SCSI_RESET_WAKEUP for
+	now.
+
+	* aha1542.c: If the command responsible for the reset is not
+	pending, return SCSI_RESET_PUNT.
+
+	* aha1740.c, buslogic.c, wd7000.c, ultrastor.c: Return
+	SCSI_RESET_PUNT instead of SCSI_RESET_SNOOZE.
+
+Tue May 31 19:36:01 1994  Eric Youngdale  (eric@esp22)
+
+	* buslogic.c: Do not print out message about "must be Adaptec"
+	if we have detected a buslogic card.  Print out a warning message
+	if we are configuring for >16Mb, since the 445S at board level
+	D or earlier does not work right.  The "D" level board can be made
+	to work by flipping an undocumented switch, but this is too subtle.
+
+    Changes based upon patches in Yggdrasil distribution.
+
+	* sg.c, sg.h: Return sense data to user.
+
+	* aha1542.c, aha1740.c, buslogic.c: Do not panic if
+	sense buffer is wrong size.
+
+	* hosts.c: Test for ultrastor card before any of the others.
+
+	* scsi.c: Allow boot-time option for max_scsi_luns=? so that
+	buggy firmware has an easy work-around.
+
+Sun May 15 20:24:34 1994  Eric Youngdale  (eric@esp22)
+
+	* Linux 1.1.15 released.
+
+	Post-codefreeze thaw...
+
+	* buslogic.[c,h]: New driver from David Gentzel.
+
+	* hosts.h: Add use_clustering field to explicitly say whether
+	clustering should be used for devices attached to this host
+	adapter.  The buslogic board apparently supports large SG lists,
+	but it is apparently faster if sd.c condenses this into a smaller
+	list.
+
+	* sd.c: Use this field instead of heuristic.
+
+	* All host adapter include files: Add appropriate initializer for
+	use_clustering field.
+
+	* scsi.h: Add #defines for return codes for the abort and reset
+	functions.  There are now a specific set of return codes to fully
+	specify all of the possible things that the low-level adapter
+	could do.
+
+	* scsi.c: Act based upon return codes from abort/reset functions.
+
+	* All host adapter abort/reset functions: Return new return code.
+
+	* Add code in scsi.c to help debug timeouts.  Use #define
+	DEBUG_TIMEOUT to enable this.
+
+	* scsi.c: If the host->irq field is set, use
+	disable_irq/enable_irq before calling queuecommand if we
+	are not already in an interrupt.  Reduce races, and we
+	can be sloppier about cli/sti in the interrupt routines now
+	(reduce interrupt latency).
+
+	* constants.c: Fix some things to eliminate warnings.  Add some
+	sense descriptions that were omitted before.
+
+	* aha1542.c: Watch for SCRD from host adapter - if we see it, set
+	a flag.  Currently we only print out the number of pending
+	commands that might need to be restarted.
+
+	* aha1542.c (aha1542_abort): Look for lost interrupts, OGMB still
+	full, and attempt to recover.  Otherwise give up.
+
+	* aha1542.c (aha1542_reset): Try BUS DEVICE RESET, and then pass
+	DID_RESET back up to the upper level code for all commands running
+	on this target (even on different LUNs).
+
+Sat May  7 14:54:01 1994
+
+	* Linux 1.1.12 released.
+
+	* st.c, st.h: New version from Kai.  Supports boot time
+	specification of number of buffers.
+
+	* wd7000.[c,h]: Updated driver from John Boyd.  Now supports
+	more than one wd7000 board in machine at one time, among other things.
+
+Wed Apr 20 22:20:35 1994
+
+	* Linux 1.1.8 released.
+
+	* sd.c: Add a few type casts where scsi_malloc is called.
+
+Wed Apr 13 12:53:29 1994
+
+	* Linux 1.1.4 released.
+
+	* scsi.c: Clean up a few printks (use %p to print pointers).
+
+Wed Apr 13 11:33:02 1994
+
+	* Linux 1.1.3 released.
+
+	* fdomain.c: Update to version 5.16 (Handle different FIFO sizes
+	better).
+
+Fri Apr  8 08:57:19 1994
+
+	* Linux 1.1.2 released.
+
+	* Throughout: SCSI portion of cluster diffs added.
+
+Tue Apr  5 07:41:50 1994
+
+	* Linux 1.1 development tree initiated.
+
+	* The linux 1.0 development tree is now effectively frozen except
+	for obvious bugfixes.

+    just generate the list of .o files.
+
+    * aha1542.c: Replace 16 with sizeof(SCpnt->sense_buffer).  Add tests
+    for addresses > 16Mb, panic if we find one.
+

+
+    * fdomain.c: Update to version 3.18.  Add new signature, register IRQ
+    with irqaction.  Use ID 7 for new board.  Be more intelligent about

+
+    * hosts.c: Do not depend upon Makefile generated count of the number
+    of low-level host adapters.
+
+    * scsi.c: Use array for scsi_command_size instead of a function.  Add
+    Texel cdrom and Maxtor XT-4380S to blacklist.  Allow compile time
+    option for no-multi lun scan.  Add semaphore for possible problems
+    with handshaking, assume device is faulty until we know it not to be
+    the case.  Add DEBUG_INIT symbol to dump info as we scan for devices.
+    Zero sense buffer so we can tell if we need to request it.  When
+    examining sense information, request sense if buffer is all zero.
+    If RESET, request sense information to see what to do next.
+
+    * scsi_debug.c: Change some constants to use symbols like INT_MAX.
+
+    * scsi_ioctl.c (kernel_scsi_ioctl): New function -for making ioctl
+    calls from kernel space.
+
+    * sd.c: Increase timeout to 300.  Use functions in constants.h to

+
+    * seagate.c: Add new compile time options for ARBITRATE,

+    when requesting sense information so that this can properly be
+    restored if we retry the command.  Set aside dma buffers assuming each
+    block is 1 page, not 1Kb minix block.
+
+    * scsi_ioctl.c: Add a few type casts.  Other minor changes.
+
+    * sd.c:  Correctly  free all scsi_malloc'd memory if we run out of
+    dma_pool. Store blocksize information for each partition.
+

+    * sd.c: Add block_fsync function to dispatch table.
+
+    * sr.c: Increase timeout to 500 from 250.  Add entry for sync in
+    dispatch table (supply NULL).  If we do not have a sectorsize,
+    try to get it in the sd_open function.  Add new function just to
+    obtain sectorsize.
+
+    * sr.h: Add needs_sector_size semaphore.
+
+    * st.c: Add NULL for fsync in dispatch table.
+

+
+    * wd7000.c: Change () to (void) in wd7000_enable_dma.
+
+Wed Mar 31 16:36:25 1993
+
+    * 0.99pl8 released.
+
+    * aha1542.c: Handle mailboxes better for 1542C.
+        Do not truncate number of cylinders at 1024 for biosparam call.
+
+    * aha1740.c: Fix a few minor bugs for multiple devices.
+        Same as above for biosparam.
+
+    * scsi.c: Add lockable semaphore for removable devices that can have
+    media removal prevented.  Add another signature for flopticals.
+    (allocate_device): Fix race condition.  Allow more space in dma pool
+    for blocksizes of up to 4Kb.
+
+    * scsi.h: Define COMMAND_SIZE.  Define a SCSI specific version of
+    INIT_REQUEST that can run with interrupts off.
+
+    * scsi_ioctl.c: Make ioctl_probe function more idiot-proof.  If
+    a removable device says ILLEGAL REQUEST to a door-locking command,
+    clear lockable flag.  Add SCSI_IOCTL_GET_IDLUN ioctl.  Do not attempt
+    to lock door for devices that do not have lockable semaphore set.
+
+    * sd.c: Fix race condition for multiple disks.  Use INIT_SCSI_REQUEST
+    instead of INIT_REQUEST.  Allow sector sizes of 1024 and 256.  For
+    removable disks that are not ready, mark them as having a media change
+    (some drives do not report this later).
+
+    * seagate.c: Use volatile keyword for memory-mapped register pointers.
+
+    * sr.c: Fix race condition, a la sd.c.  Increase the number of retries
+    to 1.  Use INIT_SCSI_REQUEST.  Allow 512 byte sector sizes.  Do a
+    read_capacity when we init the device so we know the size and
+    sectorsize.
+
+    * st.c: If ioctl not found in st.c, try scsi_ioctl for others.
+
+    * ultrastor.c: Do not truncate number of cylinders at 1024 for
+    biosparam call.
+
+    * wd7000.c: Ditto.
+    Throughout: Use COMMAND_SIZE macro to determine length of scsi
+    command.
+
+
+
+Sat Mar 13 17:31:29 1993
+
+    * 0.99pl7 released.
+
+    Throughout: Improve punctuation in some messages, and use new
+    verify_area syntax.
+
+    * aha1542.c: Handle unexpected interrupts better.
+
+    * scsi.c: Ditto.  Handle reset conditions a bit better, asking for
+    sense information and retrying if required.
+
+    * scsi_ioctl.c: Allow for 12 byte scsi commands.
+
+    * ultrastor.c: Update to use scatter-gather.
+
+Sat Feb 20 17:57:15 1993
+
+    * 0.99pl6 released.
+
+    * fdomain.c: Update to version 3.5.  Handle spurious interrupts
+    better.
+
+    * sd.c: Use register_blkdev function.
+
+    * sr.c: Ditto.
+
+    * st.c: Use register_chrdev function.
+
+    * wd7000.c: Undo previous change.
+
+Sat Feb  6 11:20:43 1993
+
+    * 0.99pl5 released.
+
+    * scsi.c: Fix bug in testing for UNIT_ATTENTION.
+
+    * wd7000.c: Check at more addresses for bios.  Fix bug in biosparam
+    (heads & sectors turned around).
+
+Wed Jan 20 18:13:59 1993
+
+    * 0.99pl4 released.
+
+    * scsi.c: Ignore leading spaces when looking for blacklisted devices.
+
+    * seagate.c: Add a few new signatures for FD cards.  Another patch
+    with SCint to fix race condition.  Use recursion_depth to keep track
+    of how many times we have been recursively called, and do not start
+    another command unless we are on the outer level.  Fixes bug
+    with Syquest cartridge drives (used to crash kernel), because
+    they do not disconnect with large data transfers.
+
+Tue Jan 12 14:33:36 1993
+
+    * 0.99pl3 released.
+
+    * fdomain.c: Update to version 3.3 (a few new signatures).
+
+    * scsi.c: Add CDU-541, Denon DRD-25X to blacklist.
+    (allocate_request, request_queueable): Init request.waiting to NULL if
+    non-buffer type of request.
+
+    * seagate.c:  Allow controller to be overridden with CONTROLLER symbol.
+    Set SCint=NULL when we are done, to remove race condition.
+
+    * st.c: Changes from Kai.
+
+Wed Dec 30 20:03:47 1992
+
+    * 0.99pl2 released.
+
+    * scsi.c: Blacklist back in.  Remove Newbury drive as other bugfix
+    eliminates need for it here.
+
+    * sd.c: Return ENODEV instead of EACCES if no such device available.
+    (sd_init) Init blkdev_fops earlier so that sd_open is available sooner.
+
+    * sr.c: Same as above for sd.c.
+
+    * st.c: Return ENODEV instead of ENXIO if no device.  Init chrdev_fops
+    sooner, so that it is always there even if no tapes.
+
+    * seagate.c (controller_type): New variable to keep track of ST0x or
+    FD.  Modify signatures list to indicate controller type, and init
+    controller_type once we find a match.
+
+    * wd7000.c (wd7000_set_sync): Remove redundant function.
+
+Sun Dec 20 16:26:24 1992
+
+    * 0.99pl1 released.
+
+    * scsi_ioctl.c: Bugfix - check dev->index, not dev->id against
+    NR_SCSI_DEVICES.
+
+    * sr_ioctl.c: Verify that device exists before allowing an ioctl.
+
+    * st.c: Patches from Kai - change timeout values, improve end of tape
+    handling.
+
+Sun Dec 13 18:15:23 1992
+
+    * 0.99 kernel released.  Baseline for this ChangeLog.
