Wed Apr 12 15:25:52 1995  Eric Youngdale  (eric@andante)

	* Linux 1.2.5 released.

	* buslogic.c: Update to version 1.15 (From Leonard N. Zubkoff).
	Fixed interrupt routine to avoid races when handling multiple
	complete commands per interrupt.  Seems to come up with faster
	cards.

	* eata_dma.c: Update to 2.3.5r. Modularize. Improved error handling
        throughout and fixed bug interrupt routine which resulted in shifted
        status bytes. Added blink LED state checks for ISA and EISA HBAs.
        Memory management bug seems to have disappeared ==> increasing
        C_P_L_CURRENT_MAX to 16 for now. Decreasing C_P_L_DIV to 3 for
        performance reasons.

	* scsi.c: If we get a FMK, EOM, or ILI when attempting to scan
	the bus, assume that it was just noise on the bus, and ignore
	the device.

	* scsi.h: Update and add a bunch of missing commands which we
	were never using.

	* sd.c: Use restore_flags in do_sd_request - this may result in
	latency conditions, but it gets rid of races and crashes.
	Do not save flags again when searching for a second command to
	queue.

	* st.c: Use bytes, not STP->buffer->buffer_size when reading
	from tape.


Tue Apr  4 09:42:08 1995  Eric Youngdale  (eric@andante)

	* Linux 1.2.2 released.

	* aha152x.c: Modularize.  Add support for PCMCIA.

	* eata.c: Update to version 2.0.  Fixed bug preventing media
	detection.  If scsi_register_host returns NULL, fail gracefully.

	* scsi.c: Detect as NEC (for photo-cd purposes) for the 84
	and 25 models as "NEC_OLDCDR".

	* scsi.h: Add define for NEC_OLDCDR

	* sr.c: Add handling for NEC_OLDCDR.  Treat as unknown.

	* u14-34f.c: Update to version 2.0.  Fixed same bug as in
	eata.c.


Mon Mar  6 11:11:20 1995  Eric Youngdale  (eric@andante)

	* Linux 1.2.0 released.  Yeah!!!

	* Minor spelling/punctuation changes throughout.  Nothing
	substantive.

Mon Feb 20 21:33:03 1995  Eric Youngdale  (eric@andante)

	* Linux 1.1.95 released.

	* qlogic.c: Update to version 0.41.

	* Linux 1.1.93 released.

	* hosts.h: Change io_port to long int from short.

 	* 53c7,8xx.c: crash on AEN fixed, SCSI reset is no longer a NOP,
 	  NULL pointer panic on odd UDCs fixed, two bugs in diagnostic output
 	  fixed, should initialize correctly if left running, now loadable,
  	  new memory allocation, extraneous diagnostic output suppressed,
 	  splx() replaced with save/restore flags. [ Drew ]

	* hosts.c, hosts.h, scsi_ioctl.c, sd.c, sd_ioctl.c, sg.c, sr.c,
	sr_ioctl.c: Add special junk at end that Emacs will use for
	formatting the file.

	* qlogic.c: Update to v0.40a.  Improve parity handling.

	* scsi.c: Add Hitachi DK312C to blacklist.  Change "};" to "}" in
	many places.  Use scsi_init_malloc to get command block - may
	need this to be dma compatible for some host adapters.
	Restore interrupts after unregistering a host.

	* sd.c: Use sti instead of restore flags - causes latency problems.

	* seagate.c: Use controller_type to determine string used when
	registering irq.

	* sr.c: More photo-cd hacks to make sure we get the xa stuff right.

	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.

	* scsi.c: Fix scan_scsis so that it can be run by a user process.
	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.

	the forbidden regions.  I am not sure - I think this is so that
	we can deal with boards that do incomplete decoding of their
	address lines for the bios chips, but I am not entirely sure.

	* buslogic.c: Set forbidden_addr stuff if using a buggy board.

	* aha1740.c: Test for NULL pointer in SCtmp.  This should not

	* scsicam.c: New file from Drew.  Read block 0 on the disk and
	read the partition table.  Attempt to deduce the geometry from
	the partition table if possible.  Only used by 53c[7,8]xx right
	now, but could be used by any device for which we have no way
	of identifying the geometry.

	* sd.c: Use device letters instead of sd%d in a lot of messages.

	* seagate.c: Fix bug that resulted in lockups with some devices.

	* sr.c (sr_open): Return -EROFS, not -EACCES if we attempt to open
	device for write.

	5.18.  Should now support TMC-3260 PCI card with 18C30 chip.

	* pas16.c: Update with new irq initialization.

	* t128.c: Update with minor cleanups.

	* scsi.c (scsi_pid): New variable - gives each command a unique

Tue Jul 26 21:36:58 1994  Eric Youngdale  (eric@esp22)

	* Linux 1.1.37 released.

	* aha1542.c: Always call aha1542_mbenable, use new udelay
	mechanism so we do not wait a long time if the board does not
	implement this command.

	* g_NCR5380.c: Remove #include <linux/config.h> and #if
	defined(CONFIG_SCSI_*).

	* seagate.c: Likewise.

	Next round of changes to support loadable modules.  Getting closer
	now, still not possible to do anything remotely usable.

	hosts.c: Create a linked list of detected high level devices.
	(scsi_register_device): New function to insert into this list.
	(scsi_init): Call scsi_register_device for each of the known high
	level drivers.

	hosts.h: Add prototype for linked list header.  Add structure
	definition for device template structure which defines the linked
	list.

	scsi.c: (scan_scsis): Use linked list instead of knowledge about
	existing high level device drivers.
	(scsi_dev_init): Use init functions for drivers on linked list
	instead of explicit list to initialize and attach devices to high
	level drivers.

	scsi.h: Add new field "attached" to scsi_device - count of number
	of high level devices attached.

	sd.c, sr.c, sg.c, st.c: Adjust init/attach functions to use new
	scheme.

Sat Jul 23 13:03:17 1994  Eric Youngdale  (eric@esp22)

Thu Jul 14 10:51:42 1994  Eric Youngdale  (eric@esp22)

	* Linux 1.1.29 released.

	* scsi.c (scan_scsis): Add new devices to end of linked list, not
	to the beginning.

	* scsi.h (SCSI_SLEEP): Remove brain dead hack to try to save
	the task state before sleeping.

Sat Jul  9 15:01:03 1994  Eric Youngdale  (eric@esp22)

	More changes to eventually support loadable modules.  Mainly
	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.

	prompt.  Supply jumpstart flag if we are resetting and need the
	command restarted.   Fix so that we return 1 if we detect a card
	so that multiple card detection works correctly.  Add yet another
	signature for FD cards (950).  Add another signature for ST0x.

	* sg.c, sg.h: New files from Lawrence Foard for generic scsi
	access.

	* sr.c:  Add type casts for (void*) so that we can do pointer
	arithmetic.  Works with GCC without this, but it is not strictly
	correct.  Same bugfix as was in sd.c.  Increase read-ahead a la
	disk driver.

	* sr_ioctl.c: Use scsi_malloc buffer instead of buffer from stack
	since we cannot guarantee that the stack is < 16Mb.

	ultrastor.c: Update to support 24f properly (JFC's driver).

	wd7000.c: Supply jumpstart flag for reset.  Do not round up
	number of cylinders in biosparam function.

Sat Sep  4 20:49:56 1993

    * 0.99pl13 released.

    * Throughout:  Use check_region/snarf_region for all low-level
    drivers.

    * aha1542.c: Do hard reset instead of soft (some ethercard probes
    screw us up).

    * scsi.c: Add new flag ASKED_FOR_SENSE so that we can tell if we are
    in a loop whereby the device returns null sense data.

    * sd.c: Add code to spin up a drive if it is not already spinning.
    Do this one at a time to make it easier on power supplies.

    * sd_ioctl.c: Use sync_dev instead of fsync_dev in BLKFLSBUF ioctl.

    * seagate.c: Switch around DATA/CONTROL lines.

    * st.c: Change sense to unsigned.

Thu Aug  5 11:59:18 1993

    * 0.99pl12 released.

    * constants.c, constants.h: New files with ascii descriptions of
    various conditions.

    * Makefile: Do not try to count the number of low-level drivers,
    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.

    * aha1740.c: Ditto with sizeof().

    * fdomain.c: Update to version 3.18.  Add new signature, register IRQ
    with irqaction.  Use ID 7 for new board.  Be more intelligent about
    obtaining the h/s/c numbers for biosparam.

    * 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
    display info.  Use scsi_malloc buffer for READ_CAPACITY, since
    we cannot guarantee that a stack based buffer is < 16Mb.

    * sd_ioctl.c: Add BLKFLSBUF ioctl.

    * seagate.c: Add new compile time options for ARBITRATE,
    SLOW_HANDSHAKE, and SLOW_RATE.  Update assembly loops for transferring
    data.  Use kernel_scsi_ioctl to request mode page with geometry.

    * sr.c: Use functions in constants.c to display messages.

    * st.c: Support for variable block size.

    * ultrastor.c: Do not use cache for tape drives.  Set
    unchecked_isa_dma flag, even though this may not be needed (gets set
    later).

Sat Jul 17 18:32:44 1993

    * 0.99pl11 released.  C++ compilable.

    * Throughout: Add type casts all over the place, and use "ip" instead
    of "info" in the various biosparam functions.

    * Makefile: Compile seagate.c with C++ compiler.

    * aha1542.c: Always set ccb pointer as this gets trashed somehow on
    some systems.  Add a few type casts.  Update biosparam function a little.

    * aha1740.c: Add a few type casts.

    * fdomain.c: Update to version 3.17 from 3.6.  Now works with
    TMC-18C50.

    * scsi.c: Minor changes here and there with datatypes.  Save use_sg
    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.

    * seagate.c: Minor cleanups here and there.

    NOT_READY to a SUGGEST_ABORT.  Fix timeout race where time might
    get decremented past zero.

    * 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: Allow another condition for power on that are normal

    * aha1542.c: Use (void) instead of () in setup_mailboxes.

    * scsi.c: Initialize transfersize and underflow fields in SCmd to 0.
    Do not panic for unsupported message bytes.

    * scsi.h: Allocate 12 bytes instead of 10 for commands.  Add
    transfersize and underflow fields.

    disconnect/reconnect, and support command linking.  Use
    transfersize and underflow fields.  Support scatter-gather.

    * sr.c, sr_ioctl.c: Use long instead of int for last parameter in sr_ioctl.
    Use buffer and buflength in do_ioctl.  Patches from Chris Newbold for
    scsi-2 audio commands.

    * ultrastor.c: Comment out in_byte (compiler warning).

    * wd7000.c: Change () to (void) in wd7000_enable_dma.

    * 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

    * 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).

    (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.

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.
