  290. additional parameter. This is used as a priority to kmalloc,
  291. and you can specify the GFP_DMA flag if you need DMA-able memory.
  292. * Makefile: For source files that are loadable, always add name
  293. to SCSI_SRCS. Fill in modules: target.

  305. could be > 16Mb if we are loading a module at runtime (i.e. use
  306. scsi_init_malloc to get some memory we know will be safe).
  307. * scsi.c: Change dma freelist to be a set of pages. This allows
  308. us to dynamically adjust the size of the list by adding more pages
  309. to the pagelist. Fix scsi_malloc and scsi_free accordingly.
  310. * scsi_module.c: Fix include.
  311. * sd.c: Declare detach function. Increment/decrement module usage
  312. count as required. Fix init functions to allow loaded devices.

  332. all been waiting for. It fixes a problem whereby the driver
  333. is not stable under heavy load. Race condition and all that.
  334. Patch from Peter Lu.

  347. scsi_do_cmd.
  348. * sr.c: More changes for Photo-CD. This apparently breaks NEC drives.
  349. * sr_ioctl.c: Support CDROMMULTISESSION ioctl.

  410. Fri Dec 2 11:24:53 1994 Eric Youngdale (eric@andante)
  411. * Linux 1.1.71 released.
  412. * sg.c: Clear buff field when not in use. Only call scsi_free if

  466. changes appear from some unknown corner of the universe.
  467. * Throughout: Change COMMAND_SIZE() to use SCpnt->cmd_len.
  468. * Throughout: Change info() low level function to take a Scsi_Host

  501. count to 0, clear this bit to allow usage to continue, wake up
  502. processes waiting.
  503. * scsi_ioctl.c: If we have an info() function, call it, otherwise
  504. if we have a "name" field, use it, else do nothing.
  505. * sd.c, sr.c: Clear cmd_len field prior to each command we
  506. generate.
  507. * sd.h: Add "has_part_table" bit to rscsi_disks.

  510. * sr.c: Bugfix from Gerd in photocd code.
  511. * sr.c: Bugfix in get_sectorsize - always use scsi_malloc buffer -
  512. we cannot guarantee that the stack is < 16Mb.

  700. definition for device template structure which defines the linked
  701. list.
  702. scsi.c: (scan_scsis): Use linked list instead of knowledge about
  703. existing high level device drivers.

  705. instead of explicit list to initialize and attach devices to high
  706. level drivers.

  738. we want to use linked lists instead of arrays because it is easier
  739. to dynamically add and remove things this way.
  740. Quite a bit more work is needed before loadable modules are
  741. possible (and usable) with scsi, but this is most of the grunge
  742. work.
  743. * Linux 1.1.28 released.
  744. * scsi.c, scsi.h (allocate_device, request_queueable): Change
  745. argument from index into scsi_devices to a pointer to the

  748. request_queueable to use new calling sequence.
  749. * Throughout: Use SCpnt->device instead of
  750. scsi_devices[SCpnt->index]. Ugh - the pointer was there all along
  751. - much cleaner this way.
  752. * scsi.c (scsi_init_malloc, scsi_free_malloc): New functions -
  753. allow us to pretend that we have a working malloc when we
  754. initialize. Use this instead of passing memory_start, memory_end
  755. around all over the place.
  756. * scsi.h, st.c, sr.c, sd.c, sg.c: Change *_init1 functions to use
  757. scsi_init_malloc, remove all arguments, no return value.
  758. * scsi.h: Remove index field from Scsi_Device and Scsi_Cmnd
  759. structs.
  760. * scsi.c (scsi_dev_init): Set up for scsi_init_malloc.
  761. (scan_scsis): Get SDpnt from scsi_init_malloc, and refresh
  762. when we discover a device. Free pointer before returning.
  763. Change scsi_devices into a linked list.
  764. * scsi.c (scan_scsis): Change to only scan one host.
  765. (scsi_dev_init): Loop over all detected hosts, and scan them.
  766. * hosts.c (scsi_init_free): Change so that number of extra bytes
  767. is stored in struct, and we do not have to pass it each time.
  768. * hosts.h: Change Scsi_Host_Template struct to include "next" and
  769. "release" functions. Initialize to NULL in all low level
  770. adapters.
  771. * hosts.c: Rename scsi_hosts to builtin_scsi_hosts, create linked
  772. list scsi_hosts, linked together with the new "next" field.
  773. Wed Jul 6 05:45:02 1994 Eric Youngdale (eric@esp22)
  774. * Linux 1.1.25 released.
  775. * aha152x.c: Changes from Juergen - cleanups and updates.
  776. * sd.c, sr.c: Use new check_media_change and revalidate
  777. file_operations fields.
  778. * st.c, st.h: Add changes from Kai Makisara, dated Jun 22.
  779. * hosts.h: Change SG_ALL back to 0xff. Apparently soft error
  780. in /dev/brain resulted in having this bumped up.
  781. Change first parameter in bios_param function to be Disk * instead
  782. of index into rscsi_disks.
  783. * sd_ioctl.c: Pass pointer to rscsi_disks element instead of index
  784. to array.
  785. * sd.h: Add struct name "scsi_disk" to typedef for Scsi_Disk.
  786. * scsi.c: Remove redundant Maxtor XT8760S from blacklist.
  787. In scsi_reset, add printk when DEBUG defined.
  788. * All low level drivers: Modify definitions of bios_param in
  789. appropriate way.
  790. Thu Jun 16 10:31:59 1994 Eric Youngdale (eric@esp22)
  791. * Linux 1.1.20 released.
  792. * scsi_ioctl.c: Only pass down the actual number of characters
  793. required to scsi_do_cmd, not the one rounded up to a even number
  794. of sectors.
  795. * ultrastor.c: Changes from Caleb Epstein for 24f cards. Support
  796. larger SG lists.
  797. * ultrastor.c: Changes from me - use scsi_register to register
  798. host. Add some consistency checking,
  799. Wed Jun 1 21:12:13 1994 Eric Youngdale (eric@esp22)
  800. * Linux 1.1.19 released.
  801. * scsi.h: Add new return code for reset() function:
  802. SCSI_RESET_PUNT.
  803. * scsi.c: Make SCSI_RESET_PUNT the same as SCSI_RESET_WAKEUP for
  804. now.
  805. * aha1542.c: If the command responsible for the reset is not
  806. pending, return SCSI_RESET_PUNT.
  807. * aha1740.c, buslogic.c, wd7000.c, ultrastor.c: Return
  808. SCSI_RESET_PUNT instead of SCSI_RESET_SNOOZE.
  809. Tue May 31 19:36:01 1994 Eric Youngdale (eric@esp22)
  810. * buslogic.c: Do not print out message about "must be Adaptec"
  811. if we have detected a buslogic card. Print out a warning message
  812. if we are configuring for >16Mb, since the 445S at board level
  813. D or earlier does not work right. The "D" level board can be made
  814. to work by flipping an undocumented switch, but this is too subtle.
  815. Changes based upon patches in Yggdrasil distribution.
  816. * sg.c, sg.h: Return sense data to user.
  817. * aha1542.c, aha1740.c, buslogic.c: Do not panic if
  818. sense buffer is wrong size.
  819. * hosts.c: Test for ultrastor card before any of the others.
  820. * scsi.c: Allow boot-time option for max_scsi_luns=? so that
  821. buggy firmware has an easy work-around.
  822. Sun May 15 20:24:34 1994 Eric Youngdale (eric@esp22)
  823. * Linux 1.1.15 released.
  824. Post-codefreeze thaw...
  825. * buslogic.[c,h]: New driver from David Gentzel.
  826. * hosts.h: Add use_clustering field to explicitly say whether
  827. clustering should be used for devices attached to this host
  828. adapter. The buslogic board apparently supports large SG lists,
  829. but it is apparently faster if sd.c condenses this into a smaller
  830. list.
  831. * sd.c: Use this field instead of heuristic.
  832. * All host adapter include files: Add appropriate initializer for
  833. use_clustering field.
  834. * scsi.h: Add #defines for return codes for the abort and reset
  835. functions. There are now a specific set of return codes to fully
  836. specify all of the possible things that the low-level adapter
  837. could do.
  838. * scsi.c: Act based upon return codes from abort/reset functions.
  839. * All host adapter abort/reset functions: Return new return code.
  840. * Add code in scsi.c to help debug timeouts. Use #define
  841. DEBUG_TIMEOUT to enable this.
  842. * scsi.c: If the host->irq field is set, use
  843. disable_irq/enable_irq before calling queuecommand if we
  844. are not already in an interrupt. Reduce races, and we
  845. can be sloppier about cli/sti in the interrupt routines now
  846. (reduce interrupt latency).
  847. * constants.c: Fix some things to eliminate warnings. Add some
  848. sense descriptions that were omitted before.
  849. * aha1542.c: Watch for SCRD from host adapter - if we see it, set
  850. a flag. Currently we only print out the number of pending
  851. commands that might need to be restarted.
  852. * aha1542.c (aha1542_abort): Look for lost interrupts, OGMB still
  853. full, and attempt to recover. Otherwise give up.
  854. * aha1542.c (aha1542_reset): Try BUS DEVICE RESET, and then pass
  855. DID_RESET back up to the upper level code for all commands running
  856. on this target (even on different LUNs).
  857. Sat May 7 14:54:01 1994
  858. * Linux 1.1.12 released.
  859. * st.c, st.h: New version from Kai. Supports boot time
  860. specification of number of buffers.
  861. * wd7000.[c,h]: Updated driver from John Boyd. Now supports
  862. more than one wd7000 board in machine at one time, among other things.
  863. Wed Apr 20 22:20:35 1994
  864. * Linux 1.1.8 released.

  867. * Linux 1.1.4 released.
  868. * scsi.c: Clean up a few printks (use %p to print pointers).
  869. Wed Apr 13 11:33:02 1994
  870. * Linux 1.1.3 released.
  871. * fdomain.c: Update to version 5.16 (Handle different FIFO sizes
  872. better).
  873. Fri Apr 8 08:57:19 1994
  874. * Linux 1.1.2 released.
  875. * Throughout: SCSI portion of cluster diffs added.
  876. Tue Apr 5 07:41:50 1994
  877. * Linux 1.1 development tree initiated.
  878. * The linux 1.0 development tree is now effectively frozen except
  879. for obvious bugfixes.

  996. verify_area in GET_IDLUN ioctl. Add new ioctls for
  997. TAGGED_QUEUE_ENABLE, DISABLE. Only allow IOCTL_SEND_COMMAND by
  998. superuser.
  999. * sd.c: Only pay attention to UNIT_ATTENTION for removable disks.
  1000. Fix bug where sometimes portions of blocks would get lost
  1001. resulting in processes hanging. Add messages when we spin up a
  1002. disk, and fix a bug in the timing. Increase read-ahead for disks
  1003. that are on a scatter-gather capable host adapter.
  1004. * seagate.c: Fix so that some parameters can be set from the lilo
  1005. prompt. Supply jumpstart flag if we are resetting and need the
  1006. command restarted. Fix so that we return 1 if we detect a card
  1007. so that multiple card detection works correctly. Add yet another
  1008. signature for FD cards (950). Add another signature for ST0x.
  1009. * sg.c, sg.h: New files from Lawrence Foard for generic scsi
  1010. access.
  1011. * sr.c: Add type casts for (void*) so that we can do pointer

  1013. correct. Same bugfix as was in sd.c. Increase read-ahead a la
  1014. disk driver.
  1015. * sr_ioctl.c: Use scsi_malloc buffer instead of buffer from stack
  1016. since we cannot guarantee that the stack is < 16Mb.
  1017. ultrastor.c: Update to support 24f properly (JFC's driver).
  1018. wd7000.c: Supply jumpstart flag for reset. Do not round up
  1019. number of cylinders in biosparam function.
  1020. Sat Sep 4 20:49:56 1993
  1021. * 0.99pl13 released.
  1022. * Throughout: Use check_region/snarf_region for all low-level
  1023. drivers.
  1024. * aha1542.c: Do hard reset instead of soft (some ethercard probes
  1025. screw us up).
  1026. * scsi.c: Add new flag ASKED_FOR_SENSE so that we can tell if we are
  1027. in a loop whereby the device returns null sense data.
  1028. * sd.c: Add code to spin up a drive if it is not already spinning.
  1029. Do this one at a time to make it easier on power supplies.
  1030. * sd_ioctl.c: Use sync_dev instead of fsync_dev in BLKFLSBUF ioctl.
  1031. * seagate.c: Switch around DATA/CONTROL lines.

  1035. * constants.c, constants.h: New files with ascii descriptions of
  1036. various conditions.
  1037. * Makefile: Do not try to count the number of low-level drivers,
  1038. just generate the list of .o files.
  1039. * aha1542.c: Replace 16 with sizeof(SCpnt->sense_buffer). Add tests
  1040. for addresses > 16Mb, panic if we find one.
  1041. * aha1740.c: Ditto with sizeof().
  1042. * fdomain.c: Update to version 3.18. Add new signature, register IRQ
  1043. with irqaction. Use ID 7 for new board. Be more intelligent about
  1044. obtaining the h/s/c numbers for biosparam.
  1045. * hosts.c: Do not depend upon Makefile generated count of the number
  1046. of low-level host adapters.
  1047. * scsi.c: Use array for scsi_command_size instead of a function. Add
  1048. Texel cdrom and Maxtor XT-4380S to blacklist. Allow compile time
  1049. option for no-multi lun scan. Add semaphore for possible problems
  1050. with handshaking, assume device is faulty until we know it not to be
  1051. the case. Add DEBUG_INIT symbol to dump info as we scan for devices.
  1052. Zero sense buffer so we can tell if we need to request it. When
  1053. examining sense information, request sense if buffer is all zero.
  1054. If RESET, request sense information to see what to do next.
  1055. * scsi_debug.c: Change some constants to use symbols like INT_MAX.
  1056. * scsi_ioctl.c (kernel_scsi_ioctl): New function -for making ioctl
  1057. calls from kernel space.
  1058. * sd.c: Increase timeout to 300. Use functions in constants.h to
  1059. display info. Use scsi_malloc buffer for READ_CAPACITY, since
  1060. we cannot guarantee that a stack based buffer is < 16Mb.
  1061. * sd_ioctl.c: Add BLKFLSBUF ioctl.
  1062. * seagate.c: Add new compile time options for ARBITRATE,
  1063. SLOW_HANDSHAKE, and SLOW_RATE. Update assembly loops for transferring
  1064. data. Use kernel_scsi_ioctl to request mode page with geometry.
  1065. * sr.c: Use functions in constants.c to display messages.
  1066. * st.c: Support for variable block size.
  1067. * ultrastor.c: Do not use cache for tape drives. Set
  1068. unchecked_isa_dma flag, even though this may not be needed (gets set
  1069. later).
  1070. Sat Jul 17 18:32:44 1993
  1071. * 0.99pl11 released. C++ compilable.
  1072. * Throughout: Add type casts all over the place, and use "ip" instead
  1073. of "info" in the various biosparam functions.
  1074. * Makefile: Compile seagate.c with C++ compiler.
  1075. * aha1542.c: Always set ccb pointer as this gets trashed somehow on
  1076. some systems. Add a few type casts. Update biosparam function a little.
  1077. * aha1740.c: Add a few type casts.
  1078. * fdomain.c: Update to version 3.17 from 3.6. Now works with
  1079. TMC-18C50.
  1080. * scsi.c: Minor changes here and there with datatypes. Save use_sg
  1081. when requesting sense information so that this can properly be
  1082. restored if we retry the command. Set aside dma buffers assuming each
  1083. block is 1 page, not 1Kb minix block.
  1084. * scsi_ioctl.c: Add a few type casts. Other minor changes.
  1085. * sd.c: Correctly free all scsi_malloc'd memory if we run out of
  1086. dma_pool. Store blocksize information for each partition.
  1087. * seagate.c: Minor cleanups here and there.
  1088. * sr.c: Set up blocksize array for all discs. Fix bug in freeing
  1089. buffers if we run out of dma pool.
  1090. Thu Jun 2 17:58:11 1993
  1091. * 0.99pl10 released.
  1092. * aha1542.c: Support for BT 445S (VL-bus board with no dma channel).
  1093. * fdomain.c: Upgrade to version 3.6. Preliminary support for TNC-18C50.
  1094. * scsi.c: First attempt to fix problem with old_use_sg. Change

  1096. get decremented past zero.
  1097. * sd.c: Add block_fsync function to dispatch table.
  1098. * sr.c: Increase timeout to 500 from 250. Add entry for sync in
  1099. dispatch table (supply NULL). If we do not have a sectorsize,
  1100. try to get it in the sd_open function. Add new function just to
  1101. obtain sectorsize.
  1102. * sr.h: Add needs_sector_size semaphore.
  1103. * st.c: Add NULL for fsync in dispatch table.
  1104. * wd7000.c: Allow another condition for power on that are normal
  1105. and do not require a panic.

  1107. * 0.99pl9 released.
  1108. * aha1542.c: Use (void) instead of () in setup_mailboxes.
  1109. * scsi.c: Initialize transfersize and underflow fields in SCmd to 0.
  1110. Do not panic for unsupported message bytes.
  1111. * scsi.h: Allocate 12 bytes instead of 10 for commands. Add
  1112. transfersize and underflow fields.
  1113. * scsi_ioctl.c: Further bugfix to ioctl_probe.
  1114. * sd.c: Use long instead of int for last parameter in sd_ioctl.
  1115. Initialize transfersize and underflow fields.
  1116. * sd_ioctl.c: Ditto for sd_ioctl(,,,,);
  1117. * seagate.c: New version from Drew. Includes new signatures for FD
  1118. cards. Support for 0ws jumper. Correctly initialize
  1119. scsi_hosts[hostnum].this_id. Improved handing of
  1120. disconnect/reconnect, and support command linking. Use
  1121. transfersize and underflow fields. Support scatter-gather.
  1122. * sr.c, sr_ioctl.c: Use long instead of int for last parameter in sr_ioctl.
  1123. Use buffer and buflength in do_ioctl. Patches from Chris Newbold for
  1124. scsi-2 audio commands.
  1125. * ultrastor.c: Comment out in_byte (compiler warning).
  1126. * wd7000.c: Change () to (void) in wd7000_enable_dma.
  1127. Wed Mar 31 16:36:25 1993

  1134. media removal prevented. Add another signature for flopticals.
  1135. (allocate_device): Fix race condition. Allow more space in dma pool
  1136. for blocksizes of up to 4Kb.
  1137. * scsi.h: Define COMMAND_SIZE. Define a SCSI specific version of
  1138. INIT_REQUEST that can run with interrupts off.
  1139. * scsi_ioctl.c: Make ioctl_probe function more idiot-proof. If
  1140. a removable device says ILLEGAL REQUEST to a door-locking command,
  1141. clear lockable flag. Add SCSI_IOCTL_GET_IDLUN ioctl. Do not attempt
  1142. to lock door for devices that do not have lockable semaphore set.
  1143. * sd.c: Fix race condition for multiple disks. Use INIT_SCSI_REQUEST
  1144. instead of INIT_REQUEST. Allow sector sizes of 1024 and 256. For
  1145. removable disks that are not ready, mark them as having a media change
  1146. (some drives do not report this later).
  1147. * seagate.c: Use volatile keyword for memory-mapped register pointers.
  1148. * sr.c: Fix race condition, a la sd.c. Increase the number of retries
  1149. to 1. Use INIT_SCSI_REQUEST. Allow 512 byte sector sizes. Do a
  1150. read_capacity when we init the device so we know the size and
  1151. sectorsize.
  1152. * st.c: If ioctl not found in st.c, try scsi_ioctl for others.
  1153. * ultrastor.c: Do not truncate number of cylinders at 1024 for
  1154. biosparam call.
  1155. * wd7000.c: Ditto.
  1156. Throughout: Use COMMAND_SIZE macro to determine length of scsi
  1157. command.
  1158. Sat Mar 13 17:31:29 1993
  1159. * 0.99pl7 released.
  1160. Throughout: Improve punctuation in some messages, and use new
  1161. verify_area syntax.
  1162. * aha1542.c: Handle unexpected interrupts better.
  1163. * scsi.c: Ditto. Handle reset conditions a bit better, asking for
  1164. sense information and retrying if required.
  1165. * scsi_ioctl.c: Allow for 12 byte scsi commands.
  1166. * ultrastor.c: Update to use scatter-gather.
  1167. Sat Feb 20 17:57:15 1993
  1168. * 0.99pl6 released.
  1169. * fdomain.c: Update to version 3.5. Handle spurious interrupts
  1170. better.

  1173. * st.c: Use register_chrdev function.
  1174. * wd7000.c: Undo previous change.
  1175. Sat Feb 6 11:20:43 1993
  1176. * 0.99pl5 released.
  1177. * scsi.c: Fix bug in testing for UNIT_ATTENTION.
  1178. * wd7000.c: Check at more addresses for bios. Fix bug in biosparam
  1179. (heads & sectors turned around).
  1180. Wed Jan 20 18:13:59 1993
  1181. * 0.99pl4 released.
  1182. * scsi.c: Ignore leading spaces when looking for blacklisted devices.
  1183. * seagate.c: Add a few new signatures for FD cards. Another patch
  1184. with SCint to fix race condition. Use recursion_depth to keep track
  1185. of how many times we have been recursively called, and do not start
  1186. another command unless we are on the outer level. Fixes bug
  1187. with Syquest cartridge drives (used to crash kernel), because
  1188. they do not disconnect with large data transfers.
  1189. Tue Jan 12 14:33:36 1993
  1190. * 0.99pl3 released.
  1191. * fdomain.c: Update to version 3.3 (a few new signatures).
  1192. * scsi.c: Add CDU-541, Denon DRD-25X to blacklist.
  1193. (allocate_request, request_queueable): Init request.waiting to NULL if
  1194. non-buffer type of request.
  1195. * seagate.c: Allow controller to be overridden with CONTROLLER symbol.
  1196. Set SCint=NULL when we are done, to remove race condition.
  1197. * st.c: Changes from Kai.
  1198. Wed Dec 30 20:03:47 1992
  1199. * 0.99pl2 released.
  1200. * scsi.c: Blacklist back in. Remove Newbury drive as other bugfix
  1201. eliminates need for it here.
  1202. * sd.c: Return ENODEV instead of EACCES if no such device available.
  1203. (sd_init) Init blkdev_fops earlier so that sd_open is available sooner.
  1204. * sr.c: Same as above for sd.c.
  1205. * st.c: Return ENODEV instead of ENXIO if no device. Init chrdev_fops
  1206. sooner, so that it is always there even if no tapes.
  1207. * seagate.c (controller_type): New variable to keep track of ST0x or
  1208. FD. Modify signatures list to indicate controller type, and init
  1209. controller_type once we find a match.
  1210. * wd7000.c (wd7000_set_sync): Remove redundant function.
  1211. Sun Dec 20 16:26:24 1992
  1212. * 0.99pl1 released.
  1213. * scsi_ioctl.c: Bugfix - check dev->index, not dev->id against
  1214. NR_SCSI_DEVICES.
  1215. * sr_ioctl.c: Verify that device exists before allowing an ioctl.
  1216. * st.c: Patches from Kai - change timeout values, improve end of tape
  1217. handling.
  1218. Sun Dec 13 18:15:23 1992
  1219. * 0.99 kernel released. Baseline for this ChangeLog.
