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.

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.

Read block 0 on the disk and + read the partition table. Attempt to deduce the geometry from + the partition table if possible.

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.

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.
