  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.
