Recent PCI chips are able to - access themselves using internal cycles, but they compare - BAR values to destination address to make decision. - Earlier chips simply use PCI transactions to access IO - registers from SCRIPTS. - The bus_dvma_to_mem() interface that reverses the actual - PCI BAR value from the BAR cookie is now useless. - This point had been discussed at the list and the solution - got approved by PCI code maintainer (Martin Mares). - - Merge changes for linux-2.4 that declare the host template - in the driver object also when the driver is statically - linked with the kernel. - - Increase SCSI message size up to 12 bytes, given that 8 - bytes was not enough for the PPR message (fix). - - Add field 'maxoffs_st' (max offset for ST data transfers). - The C1010 supports offset 62 in DT mode but only 31 in - ST mode, to 2 different values for the max SCSI offset - are needed.

Extended messages of any size are accepted now. - (Size is limited to 8 for now, but a constant is just to be - increased if necessary) - - Fix some bug in the fully untested MDP handling:) and share - some code between MDP handling and residual calculation. - - Calculate the data transfer residual as the 2's complement - integer (A positive value in returned on data overrun, and - a negative one on underrun). - - 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 Jun 5 11:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.5c - - Do not negotiate on auto-sense if we are currently using 8 bit - async transfer for the target. - - Only check for SISL/RAID on i386 platforms. - (A problem has been reported on PPC with that code). - - On MSG REJECT for a negotiation, the driver attempted to restart - the SCRIPT processor when this one was already running. - -Sat May 29 12:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.5b - - Force negotiation prior auto-sense. - This ensures that the driver will be able to grab the sense data - from a device that has received a BUS DEVICE RESET message from - another initiator. - - Complete all disconnected CCBs for a logical UNIT if we are told - about a UNIT ATTENTION for a RESET condition by this target. - - Add the control command 'cleardev' that allows to send a ABORT - message to a logical UNIT (for test purpose). - -Tue May 25 23:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.5a - - Add support for task abort and bus device reset SCSI message - and implement proper synchronisation with SCRIPTS to handle - correctly task abortion without races. - - Send an ABORT message (if untagged) or ABORT TAG message (if tagged) - when the driver is told to abort a command that is disconnected and - complete the command with appropriate error. - If the aborted command is not yet started, remove it from the start - queue and complete it with error. - - Add the control command 'resetdev' that allows to send a BUS - DEVICE RESET message to a target (for test purpose). - - Clean-up some unused or useless code. - -Fri May 21 23:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.5 - - Add support for CHMOV with Wide controllers. - - Handling of the SWIDE (low byte residue at the end of a CHMOV - in DATA IN phase with WIDE transfer when the byte count gets odd). - - Handling of the IGNORE WIDE RESIDUE message. - Handled from SCRIPTS as possible with some optimizations when both - a wide device and the controller are odd at the same time (SWIDE - present and IGNORE WIDE RESIDUE message on the BUS at the same time). - - Check against data OVERRUN/UNDERRUN condition at the end of a data - transfer, whatever a SWIDE is present (OVERRUN in DATA IN phase) - or the SODL is full (UNDERRUN in DATA out phase). - - Handling of the MODIFY DATA POINTER message. - This one cannot be handled from SCRIPTS, but hopefully it will not - happen very often. :) - - Large rewrite of the SCSI MESSAGE handling. - -Sun May 9 11:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.4 - - Support for IMMEDIATE ARBITRATION. - See the README file for detailed information about this feature. - Requires both a compile option and a boot option. - - Minor SCRIPTS optimization in reselection pattern for LUN 0. - - Simpler algorithm to deal with SCSI command starvation. - Just use 2 tag counters in flip/flop and switch to the other - one every 3 seconds. - - Do some work in SCRIPTS after the SELECT instruction and prior - to testing for a PHASE. SYMBIOS say this feature is working fine. - (Btw, only problems with Toshiba 3401B had been reported). - - Measure the PCI clock speed and do not attach controllers if - result is greater than 37 MHz. Since the precision of the - algorithm (from Stefan Esser) is better than 2%, this should - be fine. - - Fix the misdetection of SYM53C875E (was detected as a 876). - - Fix the misdetection of SYM53C810 not A (was detected as a 810A). - - Support for up to 256 TAGS per LUN (CMD_PER_LUN). - Currently limited to 255 due to Linux limitation. :) - - Support for up to 508 active commands (CAN_QUEUE). - - Support for the 53C895A by Pamela Delaney - The 53C895A contains all of the features of the 896 but has only - one channel and has a 32 bit PCI bus.

This option allows to change the - default SCSI id the driver uses for controllers. - - Make SCRIPTS not use self-mastering for PCI. - There were still 2 places the driver used this feature of the - 53C8XX family. - - Move some data structures (nvram layouts and driver set-up) to - the sym53c8xx_defs.h file. So, the both drivers will share them. - - Set MAX LUNS to 16 (instead of 8). - -Sat Mar 20 21:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.3b - - Add support for NCR PQS PDS. - James Bottomley - - Allow value 0 for host ID. - - Support more than 8 controllers (> 40 in fact :-) ) - - Add 'excl=#ioaddr' boot option: exclude controller. - (Version 1.3a driver) - -Thu Mar 11 23:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.3 (8xx-896 driver bundle) - - Equivalent changes as ncr53c8xx-3.2 due to the driver bundle. - (See Changelog.ncr53c8xx) - - Do a normal soft reset as first chip reset, since aborting current - operation may raise an interrupt we are not able to handle since - the interrupt handler is not yet established. - -Sat Mar 6 11:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.2b - - 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 21 20:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.2a - - The rewrite of the interrupt handling broke the SBMC interrupt - handling due to a 1 bit mask tiny error. Hopefully fixed. - - If INQUIRY came from a scatter list, the driver looked into - the scatterlist instead of the data.:) Since this should never - happen, we just discard the data if use_sg is not zero. - -Fri Feb 12 23:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.2 - - Major rewrite of the interrupt handling and recovery stuff for - the support of non compliant SCSI removal, insertion and all - kinds of screw-up that may happen on the SCSI BUS. - Hopefully, the driver is now unbreakable or may-be, it is just - quite broken. :-) - Many thanks to Johnson Russel (Symbios) for having responded to - my questions and for his interesting advices and comments about - support of SCSI hot-plug. - - Add 'recovery' option to driver set-up. - - Negotiate SYNC data transfers with CCS devices. - - Deal correctly with 64 bit PCI address registers on Linux 2.2. - Pointed out by Leonard Zubkoff. - -Sun Jan 31 18:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.1a - - Some 896 chip revisions (all for now :-)), may hang-up if the - soft reset bit is set at the wrong time while SCRIPTS are running. - We need to first abort the current SCRIPTS operation prior to - resetting the chip. This fix has been sent to me by SYMBIOS/LSI - and I just translated it into ncr53c8xx syntax. - Must be considered 100 % trustable, unless I did some mistake - when translating it. :-) - -Sun Jan 24 18:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.1 - - Major rewrite of the SCSI parity error handling. - The information contained in the data manuals is incomplete about - this feature. - I asked SYMBIOS about and got in reply the explanations that are - _indeed_ missing in the data manuals. - - Allow to tune request_irq() flags from the boot command line using - ncr53c8xx=irqm:??, as follows: - a) If bit 0x10 is set in irqm, SA_SHIRQ flag is not used. - b) If bit 0x20 is set in irqm, SA_INTERRUPT flag is not used. - By default the driver uses both SA_SHIRQ and SA_INTERRUPT. - Option 'ncr53c8xx=irqm:0x20' may be used when an IRQ is shared by - a 53C8XX adapter and a network board. - - Fix for 64 bit PCI address register calculation. (Lance Robinson) - - Fix for big-endian in phase mismatch handling. (Michal Jaegermann) - -Fri Jan 1 20:00 1999 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.0a - - Waiting list look-up didn't work for the first command of the list. - Hopefully fixed, but tested on paper only. ;) - - Remove the most part of PPC specific code for Linux-2.2. - Thanks to Cort. - - Some other minors changes. - -Sat Dec 19 21:00 1998 Gerard Roudier (groudier@club-internet.fr) - * version sym53c8xx-1.0 - - Define some new IO registers for the 896 (istat1, mbox0, mbox1) - - Revamp slightly the Symbios NVRAM lay-out based on the excerpt of - the header file I received from Symbios. - - Check the PCI bus number for the boot order (Using a fast - PCI controller behind a PCI-PCI bridge seems sub-optimal). - - Disable overlapped PCI arbitration for the 896 revision 1. - - Reduce a bit the number of IO register reads for phase mismatch - by reading DWORDS at a time instead of BYTES. - -Thu Dec 3 24:00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.18 - - I received this afternoon a 896 from SYMBIOS and started testing - the driver with this beast. After having fixed 3 buglets, it worked - with all features enabled including the phase mismatch handling - from SCRIPTS. Since this feature is not yet tested enough, the - boot option 'ncr53c8xx=specf:1' is still required to enable the - driver to handle PM from SCRIPTS. - -Sun Nov 29 18:00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.17 - - The SISL RAID change requires now remap_pci_mem() stuff to be - compiled for __i386__ when normal IOs are used. - - The PCI memory read from SCRIPTS that should ensure ordering - was in fact misplaced. BTW, this may explain why broken PCI - device drivers regarding ordering are working so well. ;-) - - Rewrite ncr53c8xx_setup (boot command line options) since the - binary code was a bit too bloated in my opinion. - - Make the code simpler in the wakeup_done routine. - -Tue Nov 24 23:00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.16 - - Add SCSI_NCR_OPTIMIZE_896_1 compile option and 'optim' boot option. - When set, the driver unconditionally assumes that the interrupt - handler is called for command completion, then clears INTF, scans - the done queue and returns if some completed CCB is found. If no - completed CCB are found, interrupt handling will proceed normally. - With a 896 that handles MA from SCRIPTS, this can be a great win, - since the driver will never performs PCI read transactions, but - only PCI write transactions that may be posted. - If the driver haven't to also raise the SIGP this would be perfect. - Even with this penalty, I think that this will work great. - Obviously this optimization makes sense only if the IRQ is not - shared with another device. - - 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. - -Thu Nov 19 23:00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.15 - - Add support for hardware LED control of the 896. - - Ignore chips that are driven by SISL RAID (DAC 960). - Change sent by Leonard Zubkoff and slightly reworked. - - Prevent 810A rev 11 and 860 rev 1 from using cache line based - transactions since those early chip revisions may use such on - LOAD/STORE instructions (work-around). - - Remove some useless and bloat code from the pci init stuff. - - Do not use the readX()/writeX() kernel functions for __i386__, - since they perform useless masking operations in order to deal - with broken driver in 2.1.X kernel. - -Wed Nov 11 10:00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.14 - - The driver was unhappy when configured with default_tags > MAX_TAGS - Hopefully doubly-fixed. - - Set PCI_PARITY in PCI_COMMAND register in not set (PCI fix-up). - - Print out some message if phase mismatch is handled from SCRIPTS. - -Sun Nov 1 14H00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.13 - - Some rewrite of the device detection code. This code had been - patched too much and needed to be face-lifted a bit. - Remove all platform dependent fix-ups that was not needed or - conflicted with some other driver code as work-arounds. - Reread the NVRAM before the calling of ncr_attach(). This spares - stack space and so allows to handle more boards. - Handle 64 bit base addresses under linux-2.0.X. - Set MASTER bit in PCI COMMAND register if not set. - -Wed Oct 30 22H00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.12 - - Damned! I just broke the driver for Alpha by leaving a stale - instruction in the source code. Hopefully fixed. - - Do not set PFEN when it is useless. Doing so we are sure that BOF - will be active, since the manual appears to be very unclear on what - feature is actually used by the chip when both PFEN and BOF are - set. - -Sat Oct 24 16H00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.11 - - LOAD/STORE instructions were miscompiled for register offsets - beyond 0x7f. This broke accesses to 896' new registers. - - Disable by default Phase Mismatch handling from SCRIPTS, since - current 896 rev.1 seems not to operate safely with the driver - when this feature is enabled (and above LOAD/STORE fix applied). - I will change the default to 'enabled' when this problem will be - solved. - Using boot option 'ncr53c8xx=specf:1' enables this feature. - - Implement a work-around (DEL 472 - ITEM 5) that should allow the - driver to safely enable hardware phase mismatch with 896 rev. 1. - -Tue Oct 20 22H00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.10 - - Add the 53c876 description to the chip table. This is only useful - for printing the right name of the controller. - - 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. - - 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. - - Use NAME53C and NAME53C8XX for chip name prefix chip family name. - Just give a try using "sym53c" and "sym53c8xx" instead of "ncr53c" - and "ncr53c8xx". :-) - -Sun Oct 11 17H00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.9 - - DEL-441 Item 2 work-around for the 53c876 rev <= 5 (0x15). - - Break ncr_scatter() into 2 functions in order to guarantee best - possible code optimization for the case we get a scatter list. - - Add the code intended to support up to 1 tera-byte for 64 bit systems. - It is probably too early, but I wanted to complete the thing. - -Sat Oct 3 14H00 1998 Gerard Roudier (groudier@club-internet.fr) - * version pre-sym53c8xx-0.8 - - Do some testing with io_mapped and fix what needed to be so. - - Wait for SCSI selection to complete or time-out immediately after - the chip won arbitration, since executing SCRIPTS while the SCSI - core is performing SCSI selection breaks the selection procedure - at least for some chip revisions. - - Interrupt the SCRIPTS if a device does not go to MSG OUT phase after - having been selected with ATN. Such a situation is not recoverable, - better to fail when we are stuck. diff --git a/Documentation/scsi/ChangeLog.sym53c8xx_2 b/Documentation/scsi/ChangeLog.sym53c8xx_2 deleted file mode 100644 index 9180eb343991..000000000000 --- a/Documentation/scsi/ChangeLog.sym53c8xx_2 +++ /dev/null @@ -1,144 +0,0 @@ -Sat Dec 30 21:30 2000 Gerard Roudier - * version sym-2.1.0-20001230 - - Initial release of SYM-2. - -Mon Jan 08 21:30 2001 Gerard Roudier - * version sym-2.1.1-20010108 - - Change a couple of defines containing ncr or NCR by their - equivalent containing sym or SYM instead. - -Sun Jan 14 22:30 2001 Gerard Roudier - * version sym-2.1.2-20010114 - - Fix a couple of printfs: - * Add the target number to the display of transfer parameters. - * Make the display of TCQ and queue depth clearer. - -Wed Jan 17 23:30 2001 Gerard Roudier - * version sym-2.1.3-20010117 - - Wrong residual values were returned in some situations. - This broke cdrecord with linux-2.4.0, for example. - -Sat Jan 20 18:00 2001 Gerard Roudier - * version sym-2.1.4-20010120 - - Add year 2001 to Copyright. - - A tiny bug in the dma memory freeing path has been fixed. - (Driver unload failed with a bad address reference). - -Wed Jan 24 21:00 2001 Gerard Roudier - * version sym-2.1.5-20010124 - - Make the driver work under Linux-2.4.x when statically linked - with the kernel. - - Check against memory allocation failure for SCRIPTZ and add the - missing free of this memory on instance detach. - - Check against GPIO3 pulled low for HVD controllers (driver did - just the opposite). - Misdetection of BUS mode was triggered on module reload only, - since BIOS settings were trusted instead on first load. - -Wed Feb 7 21:00 2001 Gerard Roudier - * version sym-2.1.6-20010207 - - Call pci_enable_device() as wished by kernel maintainers. - - Change the sym_queue_scsiio() interface. - This is intended to simplify portability. - - Move the code intended to deal with the downloading of SCRIPTS - from SCRIPTS :) in the patch method (was wrongly placed in - the SCRIPTS setup method). - - Add a missing cpu_to_scr() (np->abort_tbl.addr) - - Remove a wrong cpu_to_scr() (np->targtbl_ba) - - Cleanup a bit the PPR failure recovery code. - -Sat Mar 3 21:00 2001 Gerard Roudier - - Add option SYM_OPT_ANNOUNCE_TRANSFER_RATE and move the - corresponding code to file sym_misc.c. - Also move the code that sniffes INQUIRY to sym_misc.c. - This allows to share the corresponding code with NetBSD - without polluating the core driver source (sym_hipd.c). - - Add optional code that handles IO timeouts from the driver. - (not used under Linux, but required for NetBSD) - - Do not assume any longer that PAGE_SHIFT and PAGE_SIZE are - defined at compile time, as at least NetBSD uses variables - in memory for that. - - Refine a work-around for the C1010-33 that consists in - disabling internal LOAD/STORE.
