2 | * version sym53c8xx-1.7.3c | |
3 | - Ensure LEDC bit in GPCNTL is cleared when reading the NVRAM. | |
4 | Fix sent by Stig Telfer <stig@api-networks.com>. | |
5 | - Backport from SYM-2 the work-around that allows to support | |
6 | hardwares that fail PCI parity checking. | |
7 | - Check that we received at least 8 bytes of INQUIRY response | |
8 | for byte 7, that contains device capabilities, to be valid. | |
9 | - Define scsi_set_pci_device() as nil for kernel < 2.4.4. | |
10 | - + A couple of minor changes. | |

13 | * version sym53c8xx-1.7.3b | |
14 | - Fix an unaligned LOAD from scripts (was used as dummy read). | |
15 | - In ncr_soft_reset(), only try to ABORT the current operation | |
16 | for chips that support SRUN bit in ISTAT1 and if SCRIPTS are | |
17 | currently running, as 896 and 1010 manuals suggest. | |
18 | - In the CCB abort path, do not assume that the CCB is currently | |
19 | queued to SCRIPTS. This is not always true, notably after a | |
20 | QUEUE FULL status or when using untagged commands. | |

23 | * version sym53c8xx-1.7.3a | |
24 | - Fix an issue in the ncr_int_udc() (unexpected disconnect) | |
25 | handling. If the DSA didn't match a CCB, a bad write to | |
26 | memory could happen. | |

29 | * version sym53c8xx-1.7.3 | |
30 | - Support for hppa. | |
31 | Tiny patch sent to me by Robert Hirst. | |
32 | - Tiny patch for ia64 sent to me by Pamela Delaney. | |

34 | Tue Feb 6 13:30 2001 Gerard Roudier (groudier@club-internet.fr) | |
35 | * version sym53c8xx-1.7.3-pre1 | |
36 | - Call pci_enable_device() as AC wants this to be done. | |
37 | - Get both the BAR cookies used by CPU and actual PCI BAR | |
38 | values used from SCRIPTS. Recent PCI chips are able to | |
39 | access themselves using internal cycles, but they compare | |
40 | BAR values to destination address to make decision. | |
41 | Earlier chips simply use PCI transactions to access IO | |
42 | registers from SCRIPTS. | |
43 | The bus_dvma_to_mem() interface that reverses the actual | |
44 | PCI BAR value from the BAR cookie is now useless. | |
45 | This point had been discussed at the list and the solution | |
46 | got approved by PCI code maintainer (Martin Mares). | |
47 | - Merge changes for linux-2.4 that declare the host template | |
48 | in the driver object also when the driver is statically | |
49 | linked with the kernel. | |
50 | - Increase SCSI message size up to 12 bytes, given that 8 | |
51 | bytes was not enough for the PPR message (fix). | |
52 | - Add field 'maxoffs_st' (max offset for ST data transfers). | |
53 | The C1010 supports offset 62 in DT mode but only 31 in | |
54 | ST mode, to 2 different values for the max SCSI offset | |
55 | are needed. Replace the obviously wrong masking of the | |
56 | offset against 0x1f for ST mode by a lowering to | |
57 | maxoffs_st of the SCSI offset in ST mode. | |
58 | - Refine a work-around for the C1010-66. Revision 1 does | |
59 | not requires extra cycles in DT DATA OUT phase. | |
60 | - Add a missing endian-ization (abrt_tbl.addr). | |
61 | - Minor clean-up in the np structure for fields accessed | |
62 | from SCRIPTS that requires special alignments. | |

64 | Sun Sep 24 21:30 2000 Gerard Roudier (groudier@club-internet.fr) | |
65 | * version sym53c8xx-1.7.2 | |
66 | - Remove the hack for PPC added in previous driver version. | |
67 | - Add FE_DAC feature bit to distinguish between 64 bit PCI | |
68 | addressing (FE_DAC) and 64 bit PCI interface (FE_64BIT). | |
69 | - Get rid of the boot command line "ultra:" argument. | |
70 | This parameter wasn't that clever since we can use "sync:" | |
71 | for Ultra/Ultra2 settings, and for Ultra3 we may want to | |
72 | pass PPR options (for now only DT clocking). | |
73 | - Add FE_VARCLK feature bit that indicates that SCSI clock | |
74 | frequency may vary depending on board design and thus, | |
75 | the driver should try to evaluate the SCSI clock. | |
76 | - Simplify the way the driver determine the SCSI clock: | |
77 | ULTRA3 -> 160 MHz, ULTRA2 -> 80 MHz otherwise 40 MHz. | |
78 | Measure the SCSI clock frequency if FE_VARCLK is set. | |
79 | - Remove FE_CLK80 feature bit that got useless. | |
80 | - Add support for the SYM53C875A (Pamela Delaney). | |

82 | Wed Jul 26 23:30 2000 Gerard Roudier (groudier@club-internet.fr) | |
83 | * version sym53c8xx-1.7.1 | |
84 | - Provide OpenFirmare path through the proc FS on PPC. | |
85 | - Download of on-chip SRAM using memcpy_toio() doesn't work | |
86 | on PPC. Restore previous method (MEMORY MOVE from SCRIPTS). | |
87 | - Remove trailing argument #2 from a couple of #undefs. | |
88 | ||
89 | Sun Jul 09 16:30 2000 Gerard Roudier (groudier@club-internet.fr) | |
90 | * version sym53c8xx-1.7.0 | |
91 | - Remove the PROFILE C and SCRIPTS code. | |
92 | This facility was not this useful and thus was not longer | |
93 | desirable given the increasing complexity of the driver code. | |
94 | - Merges from FreeBSD sym-1.6.2 driver: | |
95 | * Clarify memory barriers needed by the driver for architectures | |
96 | that implement a weak memory ordering. | |
97 | * Simpler handling of illegal phases and data overrun from | |
98 | SCRIPTS. These errors are now immediately reported to | |
99 | the C code by an interrupt. | |
100 | * Sync the residual handling code with sym-1.6.2 and now | |
101 | report `resid' to user for linux version >= 2.3.99 | |
102 | - General cleanup: | |
103 | Move definitions for barriers and IO/MMIO operations to the | |
104 | sym53c8xx_defs.h header files. They are now shared by the | |
105 | both drivers. | |
106 | Remove unused options that claimed to optimize for the 896. | |
107 | If fact, they were not this clever. :) | |
108 | Use SCSI_NCR_IOMAPPED instead of NCR_IOMAPPED. | |
109 | Remove a couple of unused fields from data structures. | |

111 | Thu May 11 12:40 2000 Pam Delaney (pam.delaney@lsil.com) | |
112 | * version sym53c8xx-1.6b | |
113 | - Merged version. | |
114 | ||
115 | Mon Apr 24 12:00 2000 Gerard Roudier (groudier@club-internet.fr) | |
116 | * version sym53c8xx-1.5m | |
117 | - Return value 1 (instead of 0) from the driver setup routine. | |
118 | - Do not enable PCI DAC cycles. This just broke support for | |
119 | SYM534C896 on sparc64. Problem fixed by David S. Miller. | |
120 | ||
121 | Fri Apr 14 9:00 2000 Pam Delaney (pam.delaney@lsil.com) | |
122 | * version sym53c8xx-1.6b-9 | |
123 | - Added 53C1010_66 support. | |
124 | - Small fix to integrity checking code. | |
125 | - Removed requirement for integrity checking if want to run | |
126 | at ultra 3. | |
127 | ||
128 | Sat Apr 1 12:00 2000 Gerard Roudier (groudier@club-internet.fr) | |
129 | * version sym53c8xx-1.5l | |
130 | - Tiny change for __sparc__ appeared in 2.3.99-pre4.1 that | |
131 | applies to cache line size (? Probably from David S Miller). | |
132 | - Make sure no data transfer will happen for Scsi_Cmnd requests | |
133 | that supply SCSI_DATA_NONE direction (this avoids some BUG() | |
134 | statement in the PCI code when a data buffer is also supplied). | |
135 | ||
136 | Sat Mar 11 12:00 2000 Gerard Roudier (groudier@club-internet.fr) | |
137 | * version sym53c8xx-1.6b-5 | |
138 | - Test against expected data transfer direction from SCRIPTS. | |
139 | - Add support for the new dynamic dma mapping kernel interface. | |
140 | Requires Linux-2.3.47 (tested with pre-2.3.47-6). | |
141 | Many thanks to David S. Miller for his preliminary changes | |
142 | that have been useful guidelines. | |
143 | - Get data transfer direction from the scsi command structure | |
144 | (Scsi_Cmnd) with kernels that provide this information. | |
145 | ||
146 | Mon Mar 6 23:30 2000 Gerard Roudier (groudier@club-internet.fr) | |
147 | * version sym53c8xx-1.5k | |
148 | - Test against expected data transfer direction from SCRIPTS. | |
149 | - Revert the change in 'ncr_flush_done_cmds()' but unmap the | |
150 | scsi dma buffer prior to queueing the command to our done | |
151 | list. | |
152 | - Miscellaneous (minor) fixes in the code added in driver | |
153 | version 1.5j. | |
154 | ||
155 | Mon Feb 14 4:00 2000 Pam Delaney (pam.delaney@lsil.com) | |
156 | * version sym53c8xx-pre-1.6b-2. | |
157 | - Updated the SCRIPTS error handling of the SWIDE | |
158 | condition - to remove any reads of the sbdl | |
159 | register. Changes needed because the 896 and 1010 | |
160 | chips will check parity in some special circumstances. | |
161 | This will cause a parity error interrupt if not in | |
162 | data phase. Changes based on those made in the | |
163 | FreeBSD driver version 1.3.2. | |
164 | ||
165 | Sun Feb 20 11:00 2000 Gerard Roudier (groudier@club-internet.fr) | |
166 | * version sym53c8xx-1.5j | |
167 | - Add support for the new dynamic dma mapping kernel interface. | |
168 | Requires Linux-2.3.47 (tested with pre-2.3.47-6). | |
169 | Many thanks to David S. Miller for his preliminary changes | |
170 | that have been useful guidelines, for having reviewed the | |
171 | code and having tested this driver version on Ultra-Sparc. | |
172 | - 2 tiny bugs fixed in the PCI wrapper that provides support | |
173 | for early kernels without pci device structure. | |
174 | - Get data transfer direction from the scsi command structure | |
175 | (Scsi_Cmnd) with kernels that provide this information. | |
176 | - Fix an old bug that only affected 896 rev. 1 when driver | |
177 | profile support option was set in kernel configuration. | |
178 | ||
179 | Fri Jan 14 14:00 2000 Pam Delaney (pam.delaney@lsil.com) | |
180 | * version sym53c8xx-pre-1.6b-1. | |
181 | - Merge parallel driver series 1.61 and 1.5e | |
182 | ||
183 | Tue Jan 11 14:00 2000 Pam Delaney (pam.delaney@lsil.com) | |
184 | * version sym53c8xx-1.61 | |
185 | - Added support for mounting disks on wide-narrow-wide | |
186 | scsi configurations. | |
187 | - Modified offset to be a maximum of 31 in ST mode, | |
188 | 62 in DT mode. | |
189 | - Based off of 1.60 | |
190 | ||
191 | Mon Jan 10 10:00 2000 Pam Delaney (pam.delaney@lsil.com) | |
192 | * version sym53c8xx-1.60 | |
193 | - Added capability to use the integrity checking code | |
194 | in the kernel (optional). | |
195 | - Added PPR negotiation. | |
196 | - Added support for 53C1010 Ultra 3 part. | |
197 | - Based off of 1.5f | |
198 | ||
199 | Sat Jan 8 22:00 2000 Gerard Roudier (groudier@club-internet.fr) | |
200 | * version sym53c8xx-1.5h | |
201 | - Add year 2000 copyright. | |
202 | - Display correctly bus signals when bus is detected wrong. | |
203 | - Some fix for Sparc from DSM that went directly to kernel tree. | |
204 | ||
205 | Mon Dec 6 22:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
206 | * version sym53c8xx-1.5g | |
207 | - Change messages written by the driver at initialisation and | |
208 | through the /proc FS (rather cosmetic changes that consist in | |
209 | printing out the PCI bus number and PCI device/function). | |
210 | - Ensure the SCRIPTS processor is stopped while calibrating the | |
211 | SCSI clock (the initialisation code has been a bit reworked). | |
212 | Change moved to the FreeBSD sym_hipd driver). | |
213 | - Some fixes in the MODIFY_DP/IGN_RESIDUE code and residual | |
214 | calculation (moved from FreeBSD sym_hipd driver). | |
215 | - Add NVRAM support for Tekram boards that use 24C16 EEPROM. | |
216 | Code moved from the FreeBSD sym_hipd driver, since it has | |
217 | been that one that got this feature first. | |
218 | - Definitely disable overlapped PCI arbitration for all dual | |
219 | function chips, since I cannot make sure for what chip revisions | |
220 | it is actually safe. | |
221 | - Add support for the SYM53C1510D (also for ncr53c8xx). | |
222 | - Fix up properly the PCI latency timer when needed or asked for. | |
223 | - Get rid of the old PCI bios interface, but preserve kernel 2.0 | |
224 | compatibility from a simple wrapper. | |
225 | - Update the poor Tekram sync factor table. | |
226 | - Fix in a tiny 'printk' bug that may oops in case of extended | |
227 | errors (unrecovered parity error, data overrun, etc ...) | |
228 | (Sent by Pamela Delaney from LSILOGIC) | |
229 | - Remove the compilation condition about having to acquire the | |
230 | io_request_lock since it seems to be a definite feature now.:) | |
231 | - Change get_pages by GetPages since Linux >= 2.3.27 now wants | |
232 | get_pages to ever be used as a kernel symbol (from 2.3.27). | |
233 | - proc_dir structure no longer needed for kernel >= 2.3.27. | |
234 | ||
235 | Sun Oct 3 19:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
236 | * version sym53c8xx-1.5f | |
237 | - Change the way the driver checks the PCI clock frequency, so | |
238 | that overclocked PCI BUS up to 48 MHz will not be refused. | |
239 | The more the BUS is overclocked, the less the driver will | |
240 | guarantee that its measure of the SCSI clock is correct. | |
241 | - Backport some minor improvements of SCRIPTS from the sym_hipd | |
242 | driver. | |
243 | - Backport the code rewrite of the START QUEUE dequeuing (on | |
244 | bad scsi status received) from the sym_hipd driver. | |
245 | ||
246 | Sat Sep 11 11:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
247 | * version sym53c8xx-1.5e | |
248 | - New linux-2.3.13 __setup scheme support added. | |
249 | - Cleanup of the extended error status handling: | |
250 | Use 1 bit per error type. | |
251 | - Also save the extended error status prior to auto-sense. | |
252 | - Add the FE_DIFF chip feature bit to indicate support of | |
253 | diff probing from GPIO3 (825/825A/876/875). | |
254 | - Remove the quirk handling that has been useless since day one. | |
255 | - Work-around PCI chips being reported twice on some platforms. | |
256 | - Add some redundant PCI reads in order to deal with common | |
257 | bridge misbehaviour regarding posted write flushing. | |
258 | - Add some other conditionnal code for people who have to deal | |
259 | with really broken bridges (they will have to edit a source | |
260 | file to try these options). | |
261 | - Handle correctly (hopefully) jiffies wrap-around. | |
262 | - Restore the entry used to detect 875 until revision 0xff. | |
263 | (I removed it inadvertently, it seems :) ) | |
264 | - Replace __initfunc() which is deprecated stuff by __init which | |
265 | is not yet so. ;-) | |
266 | - Rewrite the MESSAGE IN scripts more generic by using a MOVE | |
267 | table indirect. Extended messages of any size are accepted now. | |
268 | (Size is limited to 8 for now, but a constant is just to be | |
269 | increased if necessary) | |
270 | - Fix some bug in the fully untested MDP handling:) and share | |
271 | some code between MDP handling and residual calculation. | |
272 | - Calculate the data transfer residual as the 2's complement | |
273 | integer (A positive value in returned on data overrun, and | |
274 | a negative one on underrun). | |
275 | - Add support of some 'resource handling' for linux-2.3.13. | |
276 | Basically the BARs have been changed to something more complex | |
277 | in the pci_dev structure. | |
278 | - Remove some deprecated code. | |
279 | ||
280 | Sat Jun 5 11:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
281 | * version sym53c8xx-1.5c | |
282 | - Do not negotiate on auto-sense if we are currently using 8 bit | |
283 | async transfer for the target. | |
284 | - Only check for SISL/RAID on i386 platforms. | |
285 | (A problem has been reported on PPC with that code). | |
286 | - On MSG REJECT for a negotiation, the driver attempted to restart | |
287 | the SCRIPT processor when this one was already running. | |
288 | ||
289 | Sat May 29 12:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
290 | * version sym53c8xx-1.5b | |
291 | - Force negotiation prior auto-sense. | |
292 | This ensures that the driver will be able to grab the sense data | |
293 | from a device that has received a BUS DEVICE RESET message from | |
294 | another initiator. | |
295 | - Complete all disconnected CCBs for a logical UNIT if we are told | |
296 | about a UNIT ATTENTION for a RESET condition by this target. | |
297 | - Add the control command 'cleardev' that allows to send a ABORT | |
298 | message to a logical UNIT (for test purpose). | |
299 | ||
300 | Tue May 25 23:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
301 | * version sym53c8xx-1.5a | |
302 | - Add support for task abort and bus device reset SCSI message | |
303 | and implement proper synchonisation with SCRIPTS to handle | |
304 | correctly task abortion without races. | |
305 | - Send an ABORT message (if untagged) or ABORT TAG message (if tagged) | |
306 | when the driver is told to abort a command that is disconnected and | |
307 | complete the command with appropriate error. | |
308 | If the aborted command is not yet started, remove it from the start | |
309 | queue and complete it with error. | |
310 | - Add the control command 'resetdev' that allows to send a BUS | |
311 | DEVICE RESET message to a target (for test purpose). | |
312 | - Clean-up some unused or useless code. | |
313 | ||
314 | Fri May 21 23:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
315 | * version sym53c8xx-1.5 | |
316 | - Add support for CHMOV with Wide controllers. | |
317 | - Handling of the SWIDE (low byte residue at the end of a CHMOV | |
318 | in DATA IN phase with WIDE transfer when the byte count gets odd). | |
319 | - Handling of the IGNORE WIDE RESIDUE message. | |
320 | Handled from SCRIPTS as possible with some optimizations when both | |
321 | a wide device and the controller are odd at the same time (SWIDE | |
322 | present and IGNORE WIDE RESIDUE message on the BUS at the same time). | |
323 | - Check against data OVERRUN/UNDERRUN condition at the end of a data | |
324 | transfer, whatever a SWIDE is present (OVERRUN in DATA IN phase) | |
325 | or the SODL is full (UNDERRUN in DATA out phase). | |
326 | - Handling of the MODIFY DATA POINTER message. | |
327 | This one cannot be handled from SCRIPTS, but hopefully it will not | |
328 | happen very often. :) | |
329 | - Large rewrite of the SCSI MESSAGE handling. | |
330 | ||
331 | Sun May 9 11:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
332 | * version sym53c8xx-1.4 | |
333 | - Support for IMMEDIATE ARBITRATION. | |
334 | See the README file for detailed information about this feature. | |
335 | Requires both a compile option and a boot option. | |
336 | - Minor SCRIPTS optimization in reselection pattern for LUN 0. | |
337 | - Simpler algorithm to deal with SCSI command starvation. | |
338 | Just use 2 tag counters in flip/flop and switch to the other | |
339 | one every 3 seconds. | |
340 | - Do some work in SCRIPTS after the SELECT instruction and prior | |
341 | to testing for a PHASE. SYMBIOS say this feature is working fine. | |
342 | (Btw, only problems with Toshiba 3401B had been reported). | |
343 | - Measure the PCI clock speed and do not attach controllers if | |
344 | result is greater than 37 MHz. Since the precision of the | |
345 | algorithm (from Stefan Esser) is better than 2%, this should | |
346 | be fine. | |
347 | - Fix the misdetection of SYM53C875E (was detected as a 876). | |
348 | - Fix the misdetection of SYM53C810 not A (was detected as a 810A). | |
349 | - Support for up to 256 TAGS per LUN (CMD_PER_LUN). | |
350 | Currently limited to 255 due to Linux limitation. :) | |
351 | - Support for up to 508 active commands (CAN_QUEUE). | |
352 | - Support for the 53C895A by Pamela Delaney <pam.delaney@lsil.com> | |
353 | The 53C895A contains all of the features of the 896 but has only | |
354 | one channel and has a 32 bit PCI bus. It does 64 bit PCI addressing | |
355 | using dual cycle PCI data transfers. | |
356 | - Miscellaneous minor fixes. | |
357 | - Some additions to the README.ncr53c8xx file. | |
358 | ||
359 | Tue Apr 15 10:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
360 | * version sym53c8xx-1.3e | |
361 | - Support for any number of LUNs (64) (SPI2-compliant). | |
362 | (Btw, this may only be ever useful under linux-2.2 ;-)) | |
363 | ||
364 | Sun Apr 11 10:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
365 | * version sym53c8xx-1.3d | |
366 | - Add 'hostid:#id' boot option. This option allows to change the | |
367 | default SCSI id the driver uses for controllers. | |
368 | - Make SCRIPTS not use self-mastering for PCI. | |
369 | There were still 2 places the driver used this feature of the | |
370 | 53C8XX family. | |
371 | - Move some data structures (nvram layouts and driver set-up) to | |
372 | the sym53c8xx_defs.h file. So, the both drivers will share them. | |
373 | - Set MAX LUNS to 16 (instead of 8). | |

376 | * version sym53c8xx-1.3b | |
377 | - Add support for NCR PQS PDS. | |
378 | James Bottomley <James.Bottomley@columbiasc.ncr.com> | |
379 | - Allow value 0 for host ID. | |
380 | - Support more than 8 controllers (> 40 in fact :-) ) | |
381 | - Add 'excl=#ioaddr' boot option: exclude controller. | |
382 | (Version 1.3a driver) | |
383 | ||
384 | Thu Mar 11 23:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
385 | * version sym53c8xx-1.3 (8xx-896 driver bundle) | |
386 | - Equivalent changes as ncr53c8xx-3.2 due to the driver bundle. | |
387 | (See Changelog.ncr53c8xx) | |
388 | - Do a normal soft reset as first chip reset, since aborting current | |
389 | operation may raise an interrupt we are not able to handle since | |
390 | the interrupt handler is not yet established. | |
391 | ||
392 | Sat Mar 6 11:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
393 | * version sym53c8xx-1.2b | |
394 | - Fix some oooold bug that hangs the bus if a device rejects a | |
395 | negotiation. Btw, the corresponding stuff also needed some cleanup | |
396 | and thus the change is a bit larger than it could have been. | |
397 | - Still some typo that made compilation fail for 64 bit (trivial fix). | |
398 | ||
399 | Sun Feb 21 20:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
400 | * version sym53c8xx-1.2a | |
401 | - The rewrite of the interrupt handling broke the SBMC interrupt | |
402 | handling due to a 1 bit mask tiny error. Hopefully fixed. | |
403 | - If INQUIRY came from a scatter list, the driver looked into | |
404 | the scatterlist instead of the data.:) Since this should never | |
405 | happen, we just discard the data if use_sg is not zero. | |
406 | ||
407 | Fri Feb 12 23:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
408 | * version sym53c8xx-1.2 | |
409 | - Major rewrite of the interrupt handling and recovery stuff for | |
410 | the support of non compliant SCSI removal, insertion and all | |
411 | kinds of screw-up that may happen on the SCSI BUS. | |
412 | Hopefully, the driver is now unbreakable or may-be, it is just | |
413 | quite brocken. :-) | |
414 | Many thanks to Johnson Russel (Symbios) for having responded to | |
415 | my questions and for his interesting advices and comments about | |
416 | support of SCSI hot-plug. | |
417 | - Add 'recovery' option to driver set-up. | |
418 | - Negotiate SYNC data transfers with CCS devices. | |
419 | - Deal correctly with 64 bit PCI address registers on Linux 2.2. | |
420 | Pointed out by Leonard Zubkoff. | |

422 | Sun Jan 31 18:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
423 | * version sym53c8xx-1.1a | |
424 | - Some 896 chip revisions (all for now :-)), may hang-up if the | |
425 | soft reset bit is set at the wrong time while SCRIPTS are running. | |
426 | We need to first abort the current SCRIPTS operation prior to | |
427 | resetting the chip. This fix has been sent to me by SYMBIOS/LSI | |
428 | and I just translated it into ncr53c8xx syntax. | |
429 | Must be considered 100 % trustable, unless I did some mistake | |
430 | when translating it. :-) | |
431 | ||
432 | Sun Jan 24 18:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
433 | * version sym53c8xx-1.1 | |
434 | - Major rewrite of the SCSI parity error handling. | |
435 | The informations contained in the data manuals are incomplete about | |
436 | this feature. | |
437 | I asked SYMBIOS about and got in reply the explanations that are | |
438 | _indeed_ missing in the data manuals. | |
439 | - Allow to tune request_irq() flags from the boot command line using | |
440 | ncr53c8xx=irqm:??, as follows: | |
441 | a) If bit 0x10 is set in irqm, SA_SHIRQ flag is not used. | |
442 | b) If bit 0x20 is set in irqm, SA_INTERRUPT flag is not used. | |
443 | By default the driver uses both SA_SHIRQ and SA_INTERRUPT. | |
444 | Option 'ncr53c8xx=irqm:0x20' may be used when an IRQ is shared by | |
445 | a 53C8XX adapter and a network board. | |
446 | - Fix for 64 bit PCI address register calculation. (Lance Robinson) | |
447 | - Fix for big-endian in phase mismatch handling. (Michal Jaegermann) | |
448 | ||
449 | Fri Jan 1 20:00 1999 Gerard Roudier (groudier@club-internet.fr) | |
450 | * version sym53c8xx-1.0a | |
451 | - Waiting list look-up didn't work for the first command of the list. | |
452 | Hopefully fixed, but tested on paper only. ;) | |
453 | - Remove the most part of PPC specific code for Linux-2.2. | |
454 | Thanks to Cort. | |
455 | - Some other minors changes. | |
456 | ||
457 | Sat Dec 19 21:00 1998 Gerard Roudier (groudier@club-internet.fr) | |
458 | * version sym53c8xx-1.0 | |
459 | - Define some new IO registers for the 896 (istat1, mbox0, mbox1) | |
460 | - Revamp slighly the Symbios NVRAM lay-out based on the excerpt of | |
461 | the header file I received from Symbios. | |
462 | - Check the PCI bus number for the boot order (Using a fast | |
463 | PCI controller behing a PCI-PCI bridge seems sub-optimal). | |
464 | - Disable overlapped PCI arbitration for the 896 revision 1. | |
465 | - Reduce a bit the number of IO register reads for phase mismatch | |
466 | by reading DWORDS at a time instead of BYTES. | |
467 | ||
468 | Thu Dec 3 24:00 1998 Gerard Roudier (groudier@club-internet.fr) | |
469 | * version pre-sym53c8xx-0.18 | |
470 | - I received this afternoon a 896 from SYMBIOS and started testing | |
471 | the driver with this beast. After having fixed 3 buglets, it worked | |
472 | with all features enabled including the phase mismatch handling | |
473 | from SCRIPTS. Since this feature is not yet tested enough, the | |
474 | boot option 'ncr53c8xx=specf:1' is still required to enable the | |
475 | driver to handle PM from SCRIPTS. | |
476 | ||
477 | Sun Nov 29 18:00 1998 Gerard Roudier (groudier@club-internet.fr) | |
478 | * version pre-sym53c8xx-0.17 | |
479 | - The SISL RAID change requires now remap_pci_mem() stuff to be | |
480 | compiled for __i386__ when normal IOs are used. | |
481 | - The PCI memory read from SCRIPTS that should ensure ordering | |
482 | was in fact misplaced. BTW, this may explain why broken PCI | |
483 | device drivers regarding ordering are working so well. ;-) | |
484 | - Rewrite ncr53c8xx_setup (boot command line options) since the | |
485 | binary code was a bit too bloated in my opinion. | |
486 | - Make the code simpler in the wakeup_done routine. | |
487 | ||
488 | Tue Nov 24 23:00 1998 Gerard Roudier (groudier@club-internet.fr) | |
489 | * version pre-sym53c8xx-0.16 | |
490 | - Add SCSI_NCR_OPTIMIZE_896_1 compile option and 'optim' boot option. | |
491 | When set, the driver unconditionnaly assumes that the interrupt | |
492 | handler is called for command completion, then clears INTF, scans | |
493 | the done queue and returns if some completed CCB is found. If no | |
494 | completed CCB are found, interrupt handling will proceed normally. | |
495 | With a 896 that handles MA from SCRIPTS, this can be a great win, | |
496 | since the driver will never performs PCI read transactions, but | |
497 | only PCI write transactions that may be posted. | |
498 | If the driver haven't to also raise the SIGP this would be perfect. | |
499 | Even with this penalty, I think that this will work great. | |
500 | Obviously this optimization makes sense only if the IRQ is not | |
501 | shared with another device. | |
502 | - Still a buglet in the tags initial settings that needed to be fixed. | |
503 | It was not possible to disable TGQ at system startup for devices | |
504 | that claim TGQ support. The driver used at least 2 for the queue | |
505 | depth but did'nt keep track of user settings for tags depth lower | |
506 | than 2. | |
507 | ||
508 | Thu Nov 19 23:00 1998 Gerard Roudier (groudier@club-internet.fr) | |
509 | * version pre-sym53c8xx-0.15 | |
510 | - Add support for hardware LED control of the 896. | |
511 | - Ignore chips that are driven by SISL RAID (DAC 960). | |
512 | Change sent by Leonard Zubkoff and slightly reworked. | |
513 | - Prevent 810A rev 11 and 860 rev 1 from using cache line based | |
514 | transactions since those early chip revisions may use such on | |
515 | LOAD/STORE instructions (work-around). | |
516 | - Remove some useless and bloat code from the pci init stuff. | |
517 | - Do not use the readX()/writeX() kernel functions for __i386__, | |
518 | since they perform useless masking operations in order to deal | |
519 | with broken driver in 2.1.X kernel. | |
520 | ||
521 | Wed Nov 11 10:00 1998 Gerard Roudier (groudier@club-internet.fr) | |
522 | * version pre-sym53c8xx-0.14 | |
523 | - The driver was unhappy when configured with default_tags > MAX_TAGS | |
524 | Hopefully doubly-fixed. | |
525 | - Set PCI_PARITY in PCI_COMMAND register in not set (PCI fix-up). | |
526 | - Print out some message if phase mismatch is handled from SCRIPTS. | |
527 | ||
528 | Sun Nov 1 14H00 1998 Gerard Roudier (groudier@club-internet.fr) | |
529 | * version pre-sym53c8xx-0.13 | |
530 | - Some rewrite of the device detection code. This code had been | |
531 | patched too much and needed to be face-lifted a bit. | |
532 | Remove all platform dependent fix-ups that was not needed or | |
533 | conflicted with some other driver code as work-arounds. | |
534 | Reread the NVRAM before the calling of ncr_attach(). This spares | |
535 | stack space and so allows to handle more boards. | |
536 | Handle 64 bit base addresses under linux-2.0.X. | |
537 | Set MASTER bit in PCI COMMAND register if not set. | |
538 | ||
539 | Wed Oct 30 22H00 1998 Gerard Roudier (groudier@club-internet.fr) | |
540 | * version pre-sym53c8xx-0.12 | |
541 | - Damned! I just broke the driver for Alpha by leaving a stale | |
542 | instruction in the source code. Hopefully fixed. | |
543 | - Do not set PFEN when it is useless. Doing so we are sure that BOF | |
544 | will be active, since the manual appears to be very unclear on what | |
545 | feature is actually used by the chip when both PFEN and BOF are | |
546 | set. | |
547 | ||
548 | Sat Oct 24 16H00 1998 Gerard Roudier (groudier@club-internet.fr) | |
549 | * version pre-sym53c8xx-0.11 | |
550 | - LOAD/STORE instructions were miscompiled for register offsets | |
551 | beyond 0x7f. This broke accesses to 896' new registers. | |
552 | - Disable by default Phase Mismatch handling from SCRIPTS, since | |
553 | current 896 rev.1 seems not to operate safely with the driver | |
554 | when this feature is enabled (and above LOAD/STORE fix applied). | |
555 | I will change the default to 'enabled' when this problem will be | |
556 | solved. | |
557 | Using boot option 'ncr53c8xx=specf:1' enables this feature. | |
558 | - Implement a work-around (DEL 472 - ITEM 5) that should allow the | |
559 | driver to safely enable hardware phase mismatch with 896 rev. 1. | |
560 | ||
561 | Tue Oct 20 22H00 1998 Gerard Roudier (groudier@club-internet.fr) | |
562 | * version pre-sym53c8xx-0.10 | |
563 | - Add the 53c876 description to the chip table. This is only useful | |
564 | for printing the right name of the controller. | |
565 | - Add additional checking of INQUIRY data: | |
566 | Check INQUIRY data received length is at least 7. Byte 7 of | |
567 | inquiry data contains device features bits and the driver might | |
568 | be confused by garbage. Also check peripheral qualifier. | |
569 | - Use a 1,3,5,...MAXTAGS*2+1 tag numbering. Previous driver could | |
570 | use any tag number from 1 to 253 and some non conformant devices | |
571 | might have problems with large tag numbers. | |
572 | - Use NAME53C and NAME53C8XX for chip name prefix chip family name. | |
573 | Just give a try using "sym53c" and "sym53c8xx" instead of "ncr53c" | |
574 | and "ncr53c8xx". :-) | |
575 | ||
576 | Sun Oct 11 17H00 1998 Gerard Roudier (groudier@club-internet.fr) | |
577 | * version pre-sym53c8xx-0.9 | |
578 | - DEL-441 Item 2 work-around for the 53c876 rev <= 5 (0x15). | |
579 | - Break ncr_scatter() into 2 functions in order to guarantee best | |
580 | possible code optimization for the case we get a scatter list. | |
581 | - Add the code intended to support up to 1 tera-byte for 64 bit systems. | |
582 | It is probably too early, but I wanted to complete the thing. | |
583 | ||
584 | Sat Oct 3 14H00 1998 Gerard Roudier (groudier@club-internet.fr) | |
585 | * version pre-sym53c8xx-0.8 | |
586 | - Do some testing with io_mapped and fix what needed to be so. | |
587 | - Wait for SCSI selection to complete or time-out immediately after | |
588 | the chip won arbitration, since executing SCRIPTS while the SCSI | |
589 | core is performing SCSI selection breaks the selection procedure | |
590 | at least for some chip revisions. | |
591 | - Interrupt the SCRIPTS if a device does not go to MSG OUT phase after | |
592 | having been selected with ATN. Such a situation is not recoverable, | |
593 | better to fail when we are stuck. |
