Since we typically do not maintain changelogs as text files in the Linux kernel, and since the ncr53c8xx changelog has not been updated since 2002, remove it.

The driver can now attach any number of - controllers (>40) and does no longer hoger stack space at - initialisation. - - Definitely disable overlapped PCI arbitration for all dual - function chips, since I cannot make sure for what chip revisions - it is actually safe. - - Add support for the SYM53C1510D. - - Update the poor Tekram sync factor table. - - Remove the compilation condition about having to acquire the - io_request_lock since it seems to be a definite feature now.:) - - proc_dir structure no longer needed for kernel >= 2.3.27. - -Sat Sep 11 18:00 1999 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.2c - - Handle correctly (hopefully) jiffies wrap-around. - - Restore the entry used to detect 875 until revision 0xff. - (I removed it inadvertently, it seems :) ) - - Replace __initfunc() which is deprecated stuff by __init which - is not yet so. ;-) - - Add support of some 'resource handling' for linux-2.3.13. - Basically the BARs have been changed to something more complex - in the pci_dev structure. - - Remove some deprecated code. - -Sat May 10 11:00 1999 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision pre-3.2b-1 - - Support for the 53C895A by Pamela Delaney <pam.delaney@xxxxxxxx> - The 53C895A contains all of the features of the 896 but has only - one channel and has a 32 bit PCI bus. It does 64 bit PCI addressing - using dual cycle PCI data transfers. - - Miscellaneous minor fixes. - - Some additions to the README.ncr53c8xx file. - -Sun Apr 11 10:00 1999 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.2a - - Add 'hostid:#id' boot option. This option allows to change the - default SCSI id the driver uses for controllers. - - Remove nvram layouts and driver set-up structures from the C source, - and use the one defined in sym53c8xx_defs.h file. - (shared by both drivers). - - Set for now MAX LUNS to 16 (instead of 8). - -Thu Mar 11 23:00 1999 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.2 (8xx-896 driver bundle) - - Only define the host template in ncr53c8xx.h and include the - sym53c8xx_defs.h file. - - Declare static all symbols that do not need to be visible from - outside the driver code. - - Add 'excl' boot command option that allows to pass to the driver - io address of devices not to attach. - - Add info() function called from the host template to print - driver/host information. - - Minor documentation additions. - -Sat Mar 6 11:00 1999 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1h - - Fix some oooold bug that hangs the bus if a device rejects a - negotiation. Btw, the corresponding stuff also needed some cleanup - and thus the change is a bit larger than it could have been. - - Still some typo that made compilation fail for 64 bit (trivial fix). - -Sun Feb 14:00 1999 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1g - - Deal correctly with 64 bit PCI address registers on Linux 2.2. - Pointed out by Leonard Zubkoff. - - Allow to tune request_irq() flags from the boot command line using - ncr53c8xx=irqm:??, as follows: - a) If bit 0x10 is set in irqm, IRQF_SHARED flag is not used. - b) If bit 0x20 is set in irqm, IRQF_DISABLED flag is not used. - By default the driver uses both IRQF_SHARED and IRQF_DISABLED. - Option 'ncr53c8xx=irqm:0x20' may be used when an IRQ is shared by - a 53C8XX adapter and a network board. - - Tiny misspelling fixed (ABORT instead of ABRT). Was fortunately - harmless. - - Negotiate SYNC data transfers with CCS devices. - -Sat Jan 16 17:30 1999 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1f - - Some PCI fix-ups not needed any more for PPC (from Cort). - - Cache line size set to 16 DWORDS for Sparc (from DSM). - - Waiting list look-up didn't work for the first command of the list. - - Remove 2 useless lines of code. - -Sun Dec 13 18:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1e - - Same work-around as for the 53c876 rev <= 0x15 for 53c896 rev 1: - Disable overlapped arbitration. This will not make difference - since the chip has on-chip RAM. - -Thu Nov 26 22:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1d - - The SISL RAID change requires now remap_pci_mem() stuff to be - compiled for __i386__ when normal IOs are used. - - Minor spelling fixes in doc files. - -Sat Nov 21 18:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1c - - Ignore chips that are driven by SISL RAID (DAC 960). - Change sent by Leonard Zubkoff and slightly reworked. - - Still a buglet in the tags initial settings that needed to be fixed. - It was not possible to disable TGQ at system startup for devices - that claim TGQ support. The driver used at least 2 for the queue - depth but didn't keep track of user settings for tags depth lower - than 2. - -Wed Nov 11 10:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1b - - The driver was unhappy when configured with default_tags > MAX_TAGS - Hopefully doubly-fixed. - - Update the Configure.help driver section that speaks of TAGS. - -Wed Oct 21 21:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.1a - - Changes from Eddie Dost for Sparc and Alpha: - ioremap/iounmap support for Sparc. - pcivtophys changed to bus_dvma_to_phys. - - Add the 53c876 description to the chip table. This is only useful - for printing the right name of the controller. - - DEL-441 Item 2 work-around for the 53c876 rev <= 5 (0x15). - - Add additional checking of INQUIRY data: - Check INQUIRY data received length is at least 7. Byte 7 of - inquiry data contains device features bits and the driver might - be confused by garbage. Also check peripheral qualifier. - - Cleanup of the SCSI tasks management: - Remove the special case for 32 tags. Now the driver only uses the - scheme that allows up to 64 tags per LUN. - Merge some code from the 896 driver. - Use a 1,3,5,...MAXTAGS*2+1 tag numbering. Previous driver could - use any tag number from 1 to 253 and some non conformant devices - might have problems with large tag numbers. - - 'no_sync' changed to 'no_disc' in the README file. This is an old - and trivial mistake that seems to demonstrate the README file is - not often read. :) - -Sun Oct 4 14:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.0i - - Cosmetic changes for sparc (but not for the driver) that needs - __irq_itoa() to be used for printed IRQ value to be understandable. - - Some problems with the driver that didn't occur using driver 2.5f - were due to a SCSI selection problem triggered by a clearly - documented feature that in fact seems not to work: (53C8XX chips - are claimed by the manuals to be able to execute SCSI scripts just - after arbitration while the SCSI core is performing SCSI selection). - This optimization is broken and has been removed. - - Some broken scsi devices are confused when a negotiation is started - on a LUN that does not correspond to a real device. According to - SCSI specs, this is a device firmware bug. This has been worked - around by only starting negotiation if the LUN has previously be - used for at least 1 successful SCSI command. - - The 'last message sent' printed out on M_REJECT message reception - was read from the SFBR i/o register after the previous message had - been sent. - This was not correct and affects all previous driver versions and - the original FreeBSD one as well. The SCSI scripts has been fixed - so that it now provides the right information to the C code. - -Sat Jul 18 13:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.0g - - Preliminary fixes for Big Endian (sent by Eddie C. Dost). - Big Endian architectures should work again with the driver. - Eddie's patch has been partially applied since current 2.1.109 - does not have all the Sparc changes of the vger tree. - - Use of BITS_PER_LONG instead of (~0UL == 0xffffffffUL) has fixed - the problem observed when the driver was compiled using EGCS or - PGCC. - -Mon Jul 13 20:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.0f - - Some spelling fixes. - - linux/config.h misplaced in ncr53c8xx.h - - MODULE_PARM stuff added for linux 2.1. - - check INQUIRY response data format is exactly 2. - - use BITS_PER_LONG if defined. - -Sun Jun 28 12:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.0e - - Some cleanup, spelling fixes, version checks, documentations - changes, etc ... - -Sat Jun 20 20:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.0c - - Add a boot setup option that allows to set up device queue depths - at boot-up. This option is very useful since Linux does not - allow to change scsi device queue depth once the system has been - booted up. - -Sun Jun 15 23:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.0a - - Support for up to 64 TAGS per LUN. - - Rewrite the TARGET vs LUN capabilities management. - CmdQueue is now handled as a LUN capability as it shall be. - This also fixes a bug triggered when disabling tagged command - queuing for a device that had this feature enabled. - - Remove the ncr_opennings() stuff that was useless under Linux - and hard to understand to me. - - Add "setverbose" procfs driver command. It allows to tune - verbose level after boot-up. Setting this level to zero, for - example avoid flooding the syslog file. - - Add KERN_XXX to some printk's. - -Tue Jun 10 23:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 3.0 - - Linux config changes for 2.0.34: - Remove NVRAM detection config option. This option is now enabled - by default but can be disabled by editing the driver header file. - Add a PROFILE config option. - - Update Configure.help - - Add calls to new function mdelay() for milli-seconds delay if - kernel version >= 2.1.105. - - Replace all printf(s) by printk(s). After all, the ncr53c8xx is - a driver for Linux. - - Perform auto-sense on COMMAND TERMINATED. Not sure it is useful. - - Some other minor changes. - -Tue Jun 4 23:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6n - - Code cleanup and simplification: - Remove kernel 1.2.X and 1.3.X support. - Remove the _old_ target capabilities table. - Remove the error recovery code that hasn't been really useful. - Use a single alignment boundary (CACHE_LINE_SIZE) for data - structures. - - Several aggressive SCRIPTS optimizations and changes: - Reselect SCRIPTS code rewritten. - Support for selection/reselection without ATN. - And some others. - - Miscallaneous changes in the C code: - Count actual number of CCB queued to the controller (future use). - Lots of other minor changes. - -Wed May 13 20:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6m - - Problem of missed SCSI bus reset with the 53C895 fixed by - Richard Waltham. The 53C895 needs about 650 us for the bus - mode to settle. Delays used while resetting the controller - and the bus have been adjusted. Thanks Richard! - - Some simplification for 64 bit arch done ccb address testing. - - Add a check of the MSG_OUT phase after Selection with ATN. - - The new tagged queue stuff seems ok, so some informationnal - message have been conditioned by verbose >= 3. - - Do not reset if a SBMC interrupt reports the same bus mode. - - Print out the whole driver set-up. Some options were missing and - the print statement was misplaced for modules. - - Ignore a SCSI parity interrupt if the chip is not connected to - the SCSI bus. - -Sat May 1 16:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6l - - Add CCB done queue support for Alpha and perhaps some other - architectures. - - Add some barriers to enforce memory ordering for x86 and - Alpha architectures. - - Fix something that looks like an old bug in the nego SIR - interrupt code in case of negotiation failure. - -Sat Apr 25 21:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6k - - Remove all accesses to the on-chip RAM from the C code: - Use SCRIPTS to load the on-chip RAM. - Use SCRIPTS to repair the start queue on selection timeout. - Use the copy of script in main memory to calculate the chip - context on phase mismatch. - - The above allows now to use the on-chip RAM without requiring - to get access to the on-chip RAM from the C code. This makes - on-chip RAM usable for linux-1.2.13 and for Linux-Alpha for - instance. - - Some simplifications and cleanups in the SCRIPTS and C code. - - Buglet fixed in parity error recovery SCRIPTS (never tested). - - Minor updates in README.ncr53c8xx. - -Wed Apr 15 21:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6j - - Incorporate changes from linux-2.1.95 ncr53c8xx driver version. - - Add SMP support for linux-2.1.95 and above. - - Fix a bug when QUEUE FULL is returned and no commands are - disconnected. This happens with Atlas I / L912 and may happen - with Atlas II / LXY4. - - Nail another one on CHECK condition when requeuing the command - for auto-sense. - - Call scsi_done() for all completed commands after interrupt - handling. - - Increase the done queue to 24 entries. - -Sat Apr 4 20:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6i - - CTEST0 is used by the 53C885 for Power Management and - priority setting between the 2 functions. - Use SDID instead as actual target number. Just have had to - overwrite it with SSID on reselection. - - Split DATA_IN and DATA_OUT scripts into 2 sub-scripts. - 64 segments are moved from on-chip RAM scripts. - If more segments, a script in main memory is used for the - additional segments. - - Since the SCRIPTS processor continues SCRIPTS execution after - having won arbitration, do some stuff prior to testing any SCSI - phase on reselection. This should have the vertue to process - scripts in parallel with the SCSI core performing selection. - - Increase the done queue to 12 entries. - -Sun Mar 29 12:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6h - - Some fixes. - -Tue Mar 26 23:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6g - - New done queue. 8 entries by default (6 always usable). - Can be increased if needed. - - Resources management using doubly linked queues. - - New auto-sense and QUEUE FULL handling that does not need to - stall the NCR queue any more. - - New CCB starvation avoiding algorithm. - - Prepare CCBs for SCSI commands that cannot be queued, instead of - inserting these commands into the waiting list. The waiting list - is now only used while resetting and when memory for CCBs is not - yet available? - -Sun Feb 8 22:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6f - - Some fixes in order to really support the 53C895, at least with - FAST-20 devices. - - Heavy changes in the target/lun resources management to allow - the scripts to jump directly to the CCB on reselection instead - of walking on the lun CCBs list. Up to 32 tags per lun are now - supported without script processor and PCI traffic overhead. - -Sun Jan 11 22:00 1998 Gerard Roudier (groudier@xxxxxxxxxxxxxxxx) - * revision 2.6d - - new (different ?) implementation of the start queue: - Use a simple CALL to a launch script in the CCB. - - implement a minimal done queue (1 entry :-) ). - this avoid scanning all CCBs on INT FLY (Only scan all CCBs, on - overflow). Hit ratio is better than 99.9 % on my system, so no - need to have a larger done queue. - - generalization of the restart of CCB on special condition as - Abort, QUEUE FULL, CHECK CONDITION. - This has been called 'silly scheduler'. - - make all the profiling code conditioned by a config option. - This spare some PCI traffic and C code when this feature is not - needed. - - handle more cleanly the situation where direction is unknown. - The pointers patching is now performed by the SCRIPTS processor. - - remove some useless scripts instructions. - - Ported from driver 2.5 series: - ------------------------------ - - Use FAST-5 instead of SLOW for slow scsi devices according to - new SPI-2 draft. - - Make some changes in order to accommodate with 875 rev <= 3 - device errata listing 397. Minor consequences are: - . Leave use of PCI Write and Invalidate under user control. - Now, by default the driver does not enable PCI MWI and option - 'specf:y' is required in order to enable this feature. - . Memory Read Line is not enabled for 875 and 875-like chips. - . Programmed burst length set to 64 DWORDS (instead of 128). - (Note: SYMBIOS uses 32 DWORDS for the SDMS BIOS) - - Add 'buschk' boot option. - This option enables checking of SCSI BUS data lines after SCSI - RESET (set by default). (Submitted by Richard Waltham). - - Update the README file. - - Dispatch CONDITION MET and RESERVATION CONFLICT scsi status - as OK driver status. - - Update the README file and the Symbios NVRAM format definition - with removable media flags values (available with SDMS 4.09). - - Several PCI configuration registers fix-ups for powerpc. - (Patch sent by Cort).
