+ 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

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

+
+Tue Nov 29 15:43:50 1994 Eric Youngdale (eric@andante.aib.com)

+ 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.

+ ISA motherboards.
+
+ * hosts.h: Add usage_count to Scsi_Host_Template.
+
+ * hosts.h: Add n_io_port to Scsi_Host (used when releasing module).

+ Move abort timeout message. Fix panic in request_queueable to
+ 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.

+
+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_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.

+ 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.

+ 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.

+ 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.
+

+
+ * seagate.c: Add new compile time options for ARBITRATE,
+ SLOW_HANDSHAKE, and SLOW_RATE. Update assembly loops for transferring

+
+ * sd.c: Fix race condition for multiple disks. Use INIT_SCSI_REQUEST
+ instead of INIT_REQUEST. Allow sector sizes of 1024 and 256. For

+
+ * seagate.c: Use volatile keyword for memory-mapped register pointers.
+
+ * sr.c: Fix race condition, a la sd.c. Increase the number of retries
