^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 200) By default the driver uses both IRQF_SHARED and IRQF_DISABLED.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 201) Option 'ncr53c8xx=irqm:0x20' may be used when an IRQ is shared by

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 248) for printing the right name of the controller.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 250) - Add additional checking of INQUIRY data:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 251) Check INQUIRY data received length is at least 7. Byte 7 of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 252) inquiry data contains device features bits and the driver might
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 253) be confused by garbage. Also check peripheral qualifier.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 254) - Cleanup of the SCSI tasks management:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 255) Remove the special case for 32 tags. Now the driver only uses the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 256) scheme that allows up to 64 tags per LUN.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 257) Merge some code from the 896 driver.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 258) Use a 1,3,5,...MAXTAGS*2+1 tag numbering. Previous driver could
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 259) use any tag number from 1 to 253 and some non conformant devices
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 260) might have problems with large tag numbers.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 261) - 'no_sync' changed to 'no_disc' in the README file. This is an old
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 262) and trivial mistake that seems to demonstrate the README file is

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 270) were due to a SCSI selection problem triggered by a clearly

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 275) - Some broken scsi devices are confused when a negotiation is started
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 276) on a LUN that does not correspond to a real device. According to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 277) SCSI specs, this is a device firmware bug. This has been worked
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 278) around by only starting negotiation if the LUN has previously be

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 439) - New auto-sense and QUEUE FULL handling that does not need to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 440) stall the NCR queue any more.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 441) - New CCB starvation avoiding algorithm.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 442) - Prepare CCBs for SCSI commands that cannot be queued, instead of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 443) inserting these commands into the waiting list. The waiting list
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 444) is now only used while resetting and when memory for CCBs is not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 445) yet available?

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 448) * revision 2.6f
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 449) - Some fixes in order to really support the 53C895, at least with
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 450) FAST-20 devices.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 451) - Heavy changes in the target/lun resources management to allow
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 452) the scripts to jump directly to the CCB on reselection instead
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 453) of walking on the lun CCBs list. Up to 32 tags per lun are now
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 454) supported without script processor and PCI traffic overhead.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 457) * revision 2.6d
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 458) - new (different ?) implementation of the start queue:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 459) Use a simple CALL to a launch script in the CCB.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 460) - implement a minimal done queue (1 entry :-) ).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 461) this avoid scanning all CCBs on INT FLY (Only scan all CCBs, on
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 462) overflow). Hit ratio is better than 99.9 % on my system, so no
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 463) need to have a larger done queue.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 464) - generalization of the restart of CCB on special condition as
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 465) Abort, QUEUE FULL, CHECK CONDITION.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 466) This has been called 'silly scheduler'.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 467) - make all the profiling code conditionned by a config option.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 468) This spare some PCI traffic and C code when this feature is not
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 469) needed.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 470) - handle more cleanly the situation where direction is unknown.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 471) The pointers patching is now performed by the SCRIPTS processor.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 472) - remove some useless scripts instructions.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 473)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 474) Ported from driver 2.5 series:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 475) ------------------------------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 476) - Use FAST-5 instead of SLOW for slow scsi devices according to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 477) new SPI-2 draft.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 478) - Make some changes in order to accommodate with 875 rev <= 3
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 479) device errata listing 397. Minor consequences are:
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 480) . Leave use of PCI Write and Invalidate under user control.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 481) Now, by default the driver does not enable PCI MWI and option
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 482) 'specf:y' is required in order to enable this feature.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 483) . Memory Read Line is not enabled for 875 and 875-like chips.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 484) . Programmed burst length set to 64 DWORDS (instead of 128).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 485) (Note: SYMBIOS uses 32 DWORDS for the SDMS BIOS)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 486) - Add 'buschk' boot option.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 487) This option enables checking of SCSI BUS data lines after SCSI
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 488) RESET (set by default). (Submitted by Richard Waltham).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 489) - Update the README file.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 490) - Dispatch CONDITION MET and RESERVATION CONFLICT scsi status
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 491) as OK driver status.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 492) - Update the README file and the Symbios NVRAM format definition
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 493) with removable media flags values (available with SDMS 4.09).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 494) - Several PCI configuration registers fix-ups for powerpc.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 495) (Patch sent by Cort).
