   1Sat Dec 30 21:30 2000 Gerard Roudier 
   2        * version sym-2.1.0-20001230
   3        - Initial release of SYM-2.
   4
   5Mon Jan 08 21:30 2001 Gerard Roudier 
   6        * version sym-2.1.1-20010108
   7        - Change a couple of defines containing ncr or NCR by their 
   8          equivalent containing sym or SYM instead.
   9
  10Sun Jan 14 22:30 2001 Gerard Roudier 
  11        * version sym-2.1.2-20010114
  12        - Fix a couple of printfs:
  13          * Add the target number to the display of transfer parameters.
  14          * Make the display of TCQ and queue depth clearer.
  15
  16Wed Jan 17 23:30 2001 Gerard Roudier 
  17        * version sym-2.1.3-20010117
  18        - Wrong residual values were returned in some situations.
  19          This broke cdrecord with linux-2.4.0, for example.
  20
  21Sat Jan 20 18:00 2001 Gerard Roudier 
  22        * version sym-2.1.4-20010120
  23        - Add year 2001 to Copyright.
  24        - A tiny bug in the dma memory freeing path has been fixed.
  25          (Driver unload failed with a bad address reference).
  26
  27Wed Jan 24 21:00 2001 Gerard Roudier 
  28        * version sym-2.1.5-20010124
  29        - Make the driver work under Linux-2.4.x when statically linked 
  30          with the kernel.
  31        - Check against memory allocation failure for SCRIPTZ and add the 
  32          missing free of this memory on instance detach.
  33        - Check against GPIO3 pulled low for HVD controllers (driver did 
  34          just the opposite).
  35          Misdetection of BUS mode was triggered on module reload only, 
  36          since BIOS settings were trusted instead on first load.
  37
  38Wed Feb 7 21:00 2001 Gerard Roudier 
  39        * version sym-2.1.6-20010207
  40        - Call pci_enable_device() as wished by kernel maintainers.
  41        - Change the sym_queue_scsiio() interface.
  42          This is intended to simplify portability.
  43        - Move the code intended to deal with the dowloading of SCRIPTS 
  44          from SCRIPTS :) in the patch method (was wrongly placed in 
  45          the SCRIPTS setup method).
  46        - Add a missing cpu_to_scr()  (np->abort_tbl.addr)
  47        - Remove a wrong cpu_to_scr() (np->targtbl_ba)
  48        - Cleanup a bit the PPR failure recovery code.
  49
  50Sat Mar 3 21:00 2001 Gerard Roudier 
  51        - Add option SYM_OPT_ANNOUNCE_TRANSFER_RATE and move the 
  52          corresponding code to file sym_misc.c.
  53          Also move the code that sniffes INQUIRY to sym_misc.c.
  54          This allows to share the corresponding code with NetBSD 
  55          without polluating the core driver source (sym_hipd.c).
  56        - Add optionnal code that handles IO timeouts from the driver.
  57          (not used under Linux, but required for NetBSD)
  58        - Donnot assume any longer that PAGE_SHIFT and PAGE_SIZE are 
  59          defined at compile time, as at least NetBSD uses variables 
  60          in memory for that.
  61        - Refine a work-around for the C1010-33 that consists in 
  62          disabling internal LOAD/STORE. Was applied up to revision 1.
  63          Is now only applied to revision 0.
  64        - Some code reorganisations due to code moves between files.
  65
  66Tues Apr 10 21:00 2001 Gerard Roudier 
  67        * version sym-2.1.9-20010412
  68        - Reset 53C896 and 53C1010 chip according to the manual.
  69          (i.e.: set the ABRT bit in ISTAT if SCRIPTS are running)
  70        - Set #LUN in request sense only if scsi version <= 2 and
  71          #LUN <= 7.
  72        - Set busy_itl in LCB to 1 if the LCB is allocated and a 
  73          SCSI command is active. This is a simplification.
  74        - In sym_hcb_free(), do not scan the free_ccbq if no CCBs 
  75          has been allocated. This fixes a panic if attach failed.
  76        - Add DT/ST (double/simple transition) in the transfer 
  77          negotiation announce.
  78        - Forces the max number of tasks per LUN to at least 64.
  79        - Use pci_set_dma_mask() for linux-2.4.3 and above.
  80        - A couple of comments fixes.
  81
  82Wed May 22:00 2001 Gerard Roudier 
  83        * version sym-2.1.10-20010509
  84        - Mask GPCNTL against 0x1c (was 0xfc) for the reading of the NVRAM.
  85          This ensure LEDC bit will not be set on 896 and later chips.
  86          Fix sent by Chip Salzenberg <chip@perlsupport.com>.
  87        - Define the number of PQS BUSes supported.
  88          Fix sent by Stig Telfer <stig@api-networks.com>
  89        - Miscellaneous common code rearrangements due to NetBSD accel 
  90          ioctl support, without impact on Linux (hopefully).
  91
  92Mon July 2 12:00 2001 Gerard Roudier 
  93        * version sym-2.1.11-20010702
  94        - Add Tekram 390 U2B/U2W SCSI LED handling.
  95          Submitted by Chip Salzenberg <chip@valinux.com>
  96        - Add call to scsi_set_pci_device() for kernels >= 2.4.4.
  97        - Check pci dma mapping failures and complete the IO with some 
  98          error when such mapping fails.
  99        - Fill in instance->max_cmd_len for kernels > 2.4.0.
 100        - A couple of tiny fixes ...
 101
 102Sun Sep 9 18:00 2001 Gerard Roudier 
 103        * version sym-2.1.12-20010909
 104        - Change my email address.
 105        - Add infrastructure for the forthcoming 64 bit DMA addressing support.
 106          (Based on PCI 64 bit patch from David S. Miller)
 107        - Donnot use anymore vm_offset_t type.
 108
 109Sat Sep 15 20:00 2001 Gerard Roudier 
 110        * version sym-2.1.13-20010916
 111        - Add support for 64 bit DMA addressing using segment registers.
 112          16 registers for up to 4 GB x 16 -> 64 GB.
 113
 114Sat Sep 22 12:00 2001 Gerard Roudier 
 115        * version sym-2.1.14-20010922
 116        - Complete rewrite of the eh handling. The driver is now using a 
 117          semaphore in order to behave synchronously as required by the eh 
 118          threads. A timer is also used to prevent from waiting indefinitely.
 119
 120Sun Sep 30 17:00 2001 Gerard Roudier 
 121        * version sym-2.1.15-20010930
 122        - Include <linux/module.h> unconditionnaly as expected by latest
 123          kernels.
 124        - Use del_timer_sync() for recent kernels to kill the driver timer 
 125          on module release.
 126
 127Sun Oct 28 15:00 2001 Gerard Roudier 
 128        * version sym-2.1.16-20011028
 129        - Slightly simplify driver configuration.
 130        - Prepare a new patch against linux-2.4.13.
 131
 132Sat Nov 17 10:00 2001 Gerard Roudier 
 133        * version sym-2.1.17
 134        - Fix a couple of gcc/gcc3 warnings.
 135        - Allocate separately from the HCB the array for CCBs hashed by DSA.
 136          All driver memory allocations are now not greater than 1 PAGE 
 137          even on PPC64 / 4KB PAGE surprising setup.
 138
 139Sat Dec 01 18:00 2001 Gerard Roudier 
 140        * version sym-2.1.17a
 141        - Use u_long instead of U32 for the IO base cookie. This is more 
 142          consistent with what archs are expecting.
 143        - Use MMIO per default for Power PC instead of some fake normal IO,
 144          as Paul Mackerras stated that MMIO works fine now on this arch.
