100 C. Linux source files modified by AdvanSys Driver
101
102 This section for historical purposes documents the changes
103 originally made to the Linux kernel source to add the advansys
104 driver. As Linux has changed some of these files have also
105 been modified.
106
107 1. linux/arch/i386/config.in:
108
109 bool 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS y
110
111 2. linux/drivers/scsi/hosts.c:
112
113 #ifdef CONFIG_SCSI_ADVANSYS
114 #include "advansys.h"
115 #endif
116
117 and after "static struct scsi_host_template builtin_scsi_hosts[] =":
118
119 #ifdef CONFIG_SCSI_ADVANSYS
120 ADVANSYS,
121 #endif
122
123 3. linux/drivers/scsi/Makefile:
124
125 ifdef CONFIG_SCSI_ADVANSYS
126 SCSI_SRCS := $(SCSI_SRCS) advansys.c
127 SCSI_OBJS := $(SCSI_OBJS) advansys.o
128 else
129 SCSI_MODULE_OBJS := $(SCSI_MODULE_OBJS) advansys.o
130 endif
131
132 4. linux/init/main.c:
133
134 extern void advansys_setup(char *str, int *ints);
135
136 and add the following lines to the bootsetups[] array.
137
138 #ifdef CONFIG_SCSI_ADVANSYS
139 { "advansys=", advansys_setup },
140 #endif
141
142 D. Source Comments
143
144 1. Use tab stops set to 4 for the source files. For vi use 'se tabstops=4'.
145
146 2. This driver should be maintained in multiple files. But to make
147 it easier to include with Linux and to follow Linux conventions,
148 the whole driver is maintained in the source files advansys.h and
149 advansys.c. In this file logical sections of the driver begin with
150 a comment that contains '---'. The following are the logical sections
151 of the driver below.

173 or that contains a problem that needs to be addressed.
174
175 4. I have stripped comments from and reformatted the source for the
176 Asc Library and Adv Library to reduce the size of this file. This
177 source can be found under the following headings. The Asc Library
178 is used to support Narrow Boards. The Adv Library is used to
179 support Wide Boards.

185
186 E. Driver Compile Time Options and Debugging
187
188 In this source file the following constants can be defined. They are
189 defined in the source below. Both of these options are enabled by
190 default.
191
192 1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
193
194 Enabling this option adds assertion logic statements to the
195 driver. If an assertion fails a message will be displayed to
196 the console, but the system will continue to operate. Any
197 assertions encountered should be reported to the person
198 responsible for the driver. Assertion statements may proactively
199 detect problems with the driver and facilitate fixing these
200 problems. Enabling assertions will add a small overhead to the
201 execution of the driver.
202
203 2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
204
205 Enabling this option adds tracing functions to the driver and
206 the ability to set a driver tracing level at boot time. This
207 option will also export symbols not required outside the driver to
208 the kernel name space. This option is very useful for debugging
209 the driver, but it will add to the size of the driver execution
210 image and add overhead to the execution of the driver.
211
212 The amount of debugging output can be controlled with the global
213 variable 'asc_dbglvl'. The higher the number the more output. By
214 default the debug level is 0.
215
216 If the driver is loaded at boot time and the LILO Driver Option
217 is included in the system, the debug level can be changed by
218 specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
219 first three hex digits of the pseudo I/O Port must be set to
220 'deb' and the fourth hex digit specifies the debug level: 0 - F.
221 The following command line will look for an adapter at 0x330
222 and set the debug level to 2.
223
224 linux advansys=0x330,0,0,0,0xdeb2
225
226 If the driver is built as a loadable module this variable can be
227 defined when the driver is loaded. The following insmod command
228 will set the debug level to one.
229
230 insmod advansys.o asc_dbglvl=1
231
232 Debugging Message Levels:
233 0: Errors Only
234 1: High-Level Tracing
235 2-N: Verbose Tracing
236
237 To enable debug output to console, please make sure that:
238
239 a. System and kernel logging is enabled (syslogd, klogd running).
240 b. Kernel messages are routed to console output. Check
241 /etc/syslog.conf for an entry similar to this:
242
243 kern.* /dev/console
244
245 c. klogd is started with the appropriate -c parameter
246 (e.g. klogd -c 8)
247
248 This will cause printk() messages to be be displayed on the
249 current console. Refer to the klogd(8) and syslogd(8) man pages
250 for details.
251
252 Alternatively you can enable printk() to console with this
253 program. However, this is not the 'official' way to do this.
254 Debug output is logged in /var/log/messages.
255
256 main()
257 {
258 syscall(103, 7, 0, 0);
259 }
260
261 Increasing LOG_BUF_LEN in kernel/printk.c to something like
262 40960 allows more debug messages to be buffered in the kernel
263 and written to the console or log file.
264
265 3. ADVANSYS_STATS - Enable statistics (Def: Enabled >= v1.3.0)
266
267 Enabling this option adds statistics collection and display
268 through /proc to the driver. The information is useful for
269 monitoring driver and device performance. It will add to the
270 size of the driver execution image and add minor overhead to
271 the execution of the driver.
272
273 Statistics are maintained on a per adapter basis. Driver entry
274 point call counts and transfer size counts are maintained.
275 Statistics are only available for kernels greater than or equal
276 to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
277
278 AdvanSys SCSI adapter files have the following path name format:
279
280 /proc/scsi/advansys/[0-(ASC_NUM_BOARD_SUPPORTED-1)]
281
282 This information can be displayed with cat. For example:
283
284 cat /proc/scsi/advansys/0
285
286 When ADVANSYS_STATS is not defined the AdvanSys /proc files only
287 contain adapter and device configuration information.
288
289 F. Driver LILO Option
290
291 If init/main.c is modified as described in the 'Directions for Adding
292 the AdvanSys Driver to Linux' section (B.4.) above, the driver will
293 recognize the 'advansys' LILO command line and /etc/lilo.conf option.
294 This option can be used to either disable I/O port scanning or to limit
295 scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
296 PCI boards will still be searched for and detected. This option only
297 affects searching for ISA and VL boards.
298
299 Examples:
300 1. Eliminate I/O port scanning:
301 boot: linux advansys=
302 or
303 boot: linux advansys=0x0
304 2. Limit I/O port scanning to one I/O port:
305 boot: linux advansys=0x110
306 3. Limit I/O port scanning to four I/O ports:
307 boot: linux advansys=0x110,0x210,0x230,0x330
308
309 For a loadable module the same effect can be achieved by setting
310 the 'asc_iopflag' variable and 'asc_ioport' array when loading
311 the driver, e.g.
312
313 insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
314
315 If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
316 I/O Port may be added to specify the driver debug level. Refer to
317 the 'Driver Compile Time Options and Debugging' section above for
318 more information.
319
320 G. Tests to run before releasing new driver
321
322 1. In the supported kernels verify there are no warning or compile
323 errors when the kernel is built as both a driver and as a module
324 and with the following options:
325
326 ADVANSYS_DEBUG - enabled and disabled
327 CONFIG_SMP - enabled and disabled
328 CONFIG_PROC_FS - enabled and disabled
329
330 2. Run tests on an x86, alpha, and PowerPC with at least one narrow
331 card and one wide card attached to a hard disk and CD-ROM drive:
332 fdisk, mkfs, fsck, bonnie, copy/compare test from the
333 CD-ROM to the hard drive.
334
335 H. Release History
336
337 BETA-1.0 (12/23/95):
338 First Release
339
340 BETA-1.1 (12/28/95):
341 1. Prevent advansys_detect() from being called twice.
342 2. Add LILO 0xdeb[0-f] option to set 'asc_dbglvl'.
343
344 1.2 (1/12/96):
345 1. Prevent re-entrancy in the interrupt handler which
346 resulted in the driver hanging Linux.
347 2. Fix problem that prevented ABP-940 cards from being
348 recognized on some PCI motherboards.
349 3. Add support for the ABP-5140 PnP ISA card.
350 4. Fix check condition return status.
351 5. Add conditionally compiled code for Linux v1.3.X.
352
353 1.3 (2/23/96):
354 1. Fix problem in advansys_biosparam() that resulted in the
355 wrong drive geometry being returned for drives > 1GB with
356 extended translation enabled.
357 2. Add additional tracing during device initialization.
358 3. Change code that only applies to ISA PnP adapter.
359 4. Eliminate 'make dep' warning.
360 5. Try to fix problem with handling resets by increasing their
361 timeout value.
362
363 1.4 (5/8/96):
364 1. Change definitions to eliminate conflicts with other subsystems.
365 2. Add versioning code for the shared interrupt changes.
366 3. Eliminate problem in asc_rmqueue() with iterating after removing
367 a request.
368 4. Remove reset request loop problem from the "Known Problems or
369 Issues" section. This problem was isolated and fixed in the
370 mid-level SCSI driver.
371
372 1.5 (8/8/96):
373 1. Add support for ABP-940U (PCI Ultra) adapter.
374 2. Add support for IRQ sharing by setting the IRQF_SHARED flag for
375 request_irq and supplying a dev_id pointer to both request_irq()
376 and free_irq().
377 3. In AscSearchIOPortAddr11() restore a call to check_region() which
378 should be used before I/O port probing.
379 4. Fix bug in asc_prt_hex() which resulted in the displaying
380 the wrong data.
381 5. Incorporate miscellaneous Asc Library bug fixes and new microcode.
382 6. Change driver versioning to be specific to each Linux sub-level.
383 7. Change statistics gathering to be per adapter instead of global
384 to the driver.
385 8. Add more information and statistics to the adapter /proc file:
386 /proc/scsi/advansys[0...].
387 9. Remove 'cmd_per_lun' from the "Known Problems or Issues" list.
388 This problem has been addressed with the SCSI mid-level changes
389 made in v1.3.89. The advansys_select_queue_depths() function
390 was added for the v1.3.89 changes.
391
392 1.6 (9/10/96):
393 1. Incorporate miscellaneous Asc Library bug fixes and new microcode.
394
395 1.7 (9/25/96):
396 1. Enable clustering and optimize the setting of the maximum number
397 of scatter gather elements for any particular board. Clustering
398 increases CPU utilization, but results in a relatively larger
399 increase in I/O throughput.
400 2. Improve the performance of the request queuing functions by
401 adding a last pointer to the queue structure.
402 3. Correct problems with reset and abort request handling that
403 could have hung or crashed Linux.
404 4. Add more information to the adapter /proc file:
405 /proc/scsi/advansys[0...].
406 5. Remove the request timeout issue form the driver issues list.
407 6. Miscellaneous documentation additions and changes.
408
409 1.8 (10/4/96):
410 1. Make changes to handle the new v2.1.0 kernel memory mapping
411 in which a kernel virtual address may not be equivalent to its
412 bus or DMA memory address.
413 2. Change abort and reset request handling to make it yet even
414 more robust.
415 3. Try to mitigate request starvation by sending ordered requests
416 to heavily loaded, tag queuing enabled devices.
417 4. Maintain statistics on request response time.
418 5. Add request response time statistics and other information to
419 the adapter /proc file: /proc/scsi/advansys[0...].
420
421 1.9 (10/21/96):
422 1. Add conditionally compiled code (ASC_QUEUE_FLOW_CONTROL) to
423 make use of mid-level SCSI driver device queue depth flow
424 control mechanism. This will eliminate aborts caused by a
425 device being unable to keep up with requests and eliminate
426 repeat busy or QUEUE FULL status returned by a device.
427 2. Incorporate miscellaneous Asc Library bug fixes.
428 3. To allow the driver to work in kernels with broken module
429 support set 'cmd_per_lun' if the driver is compiled as a
430 module. This change affects kernels v1.3.89 to present.
431 4. Remove PCI BIOS address from the driver banner. The PCI BIOS
432 is relocated by the motherboard BIOS and its new address can
433 not be determined by the driver.
434 5. Add mid-level SCSI queue depth information to the adapter
435 /proc file: /proc/scsi/advansys[0...].
436
437 2.0 (11/14/96):
438 1. Change allocation of global structures used for device
439 initialization to guarantee they are in DMA-able memory.
440 Previously when the driver was loaded as a module these
441 structures might not have been in DMA-able memory, causing
442 device initialization to fail.
443
444 2.1 (12/30/96):
445 1. In advansys_reset(), if the request is a synchronous reset
446 request, even if the request serial number has changed, then
447 complete the request.
448 2. Add Asc Library bug fixes including new microcode.
449 3. Clear inquiry buffer before using it.
450 4. Correct ifdef typo.
451
452 2.2 (1/15/97):
453 1. Add Asc Library bug fixes including new microcode.
454 2. Add synchronous data transfer rate information to the
455 adapter /proc file: /proc/scsi/advansys[0...].
456 3. Change ADVANSYS_DEBUG to be disabled by default. This
457 will reduce the size of the driver image, eliminate execution
458 overhead, and remove unneeded symbols from the kernel symbol
459 space that were previously added by the driver.
460 4. Add new compile-time option ADVANSYS_ASSERT for assertion
461 code that used to be defined within ADVANSYS_DEBUG. This
462 option is enabled by default.
463
464 2.8 (5/26/97):
465 1. Change version number to 2.8 to synchronize the Linux driver
466 version numbering with other AdvanSys drivers.
467 2. Reformat source files without tabs to present the same view
468 of the file to everyone regardless of the editor tab setting
469 being used.
470 3. Add Asc Library bug fixes.
471
472 3.1A (1/8/98):
473 1. Change version number to 3.1 to indicate that support for
474 Ultra-Wide adapters (ABP-940UW) is included in this release.
475 2. Add Asc Library (Narrow Board) bug fixes.
476 3. Report an underrun condition with the host status byte set
477 to DID_UNDERRUN. Currently DID_UNDERRUN is defined to 0 which
478 causes the underrun condition to be ignored. When Linux defines
479 its own DID_UNDERRUN the constant defined in this file can be
480 removed.
481 4. Add patch to AscWaitTixISRDone().
482 5. Add support for up to 16 different AdvanSys host adapter SCSI
483 channels in one system. This allows four cards with four channels
484 to be used in one system.
485
486 3.1B (1/9/98):
487 1. Handle that PCI register base addresses are not always page
488 aligned even though ioremap() requires that the address argument
489 be page aligned.
490
491 3.1C (1/10/98):
492 1. Update latest BIOS version checked for from the /proc file.
493 2. Don't set microcode SDTR variable at initialization. Instead
494 wait until device capabilities have been detected from an Inquiry
495 command.
496
497 3.1D (1/21/98):
498 1. Improve performance when the driver is compiled as module by
499 allowing up to 64 scatter-gather elements instead of 8.
500
501 3.1E (5/1/98):
502 1. Set time delay in AscWaitTixISRDone() to 1000 ms.
503 2. Include SMP locking changes.
504 3. For v2.1.93 and newer kernels use CONFIG_PCI and new PCI BIOS
505 access functions.
506 4. Update board serial number printing.
507 5. Try allocating an IRQ both with and without the IRQF_DISABLED
508 flag set to allow IRQ sharing with drivers that do not set
509 the IRQF_DISABLED flag. Also display a more descriptive error
510 message if request_irq() fails.
511 6. Update to latest Asc and Adv Libraries.
512
513 3.2A (7/22/99):
514 1. Update Adv Library to 4.16 which includes support for
515 the ASC38C0800 (Ultra2/LVD) IC.
516
517 3.2B (8/23/99):
518 1. Correct PCI compile time option for v2.1.93 and greater
519 kernels, advansys_info() string, and debug compile time
520 option.
521 2. Correct DvcSleepMilliSecond() for v2.1.0 and greater
522 kernels. This caused an LVD detection/BIST problem problem
523 among other things.
524 3. Sort PCI cards by PCI Bus, Slot, Function ascending order
525 to be consistent with the BIOS.
526 4. Update to Asc Library S121 and Adv Library 5.2.
527
528 3.2C (8/24/99):
529 1. Correct PCI card detection bug introduced in 3.2B that
530 prevented PCI cards from being detected in kernels older
531 than v2.1.93.
532
533 3.2D (8/26/99):
534 1. Correct /proc device synchronous speed information display.
535 Also when re-negotiation is pending for a target device
536 note this condition with an * and footnote.
537 2. Correct initialization problem with Ultra-Wide cards that
538 have a pre-3.2 BIOS. A microcode variable changed locations
539 in 3.2 and greater BIOSes which caused WDTR to be attempted
540 erroneously with drives that don't support WDTR.
541
542 3.2E (8/30/99):
543 1. Fix compile error caused by v2.3.13 PCI structure change.
544 2. Remove field from ASCEEP_CONFIG that resulted in an EEPROM
545 checksum error for ISA cards.
546 3. Remove ASC_QUEUE_FLOW_CONTROL conditional code. The mid-level
547 SCSI changes that it depended on were never included in Linux.
548
549 3.2F (9/3/99):
550 1. Handle new initial function code added in v2.3.16 for all
551 driver versions.
552
553 3.2G (9/8/99):
554 1. Fix PCI board detection in v2.3.13 and greater kernels.
555 2. Fix comiple errors in v2.3.X with debugging enabled.
556
557 3.2H (9/13/99):
558 1. Add 64-bit address, long support for Alpha and UltraSPARC.
559 The driver has been verified to work on an Alpha system.
560 2. Add partial byte order handling support for Power PC and
561 other big-endian platforms. This support has not yet been
562 completed or verified.
563 3. For wide boards replace block zeroing of request and
564 scatter-gather structures with individual field initialization
565 to improve performance.
566 4. Correct and clarify ROM BIOS version detection.
567
568 3.2I (10/8/99):
569 1. Update to Adv Library 5.4.
570 2. Add v2.3.19 underrun reporting to asc_isr_callback() and
571 adv_isr_callback(). Remove DID_UNDERRUN constant and other
572 no longer needed code that previously documented the lack
573 of underrun handling.
574
575 3.2J (10/14/99):
576 1. Eliminate compile errors for v2.0 and earlier kernels.
577
578 3.2K (11/15/99):
579 1. Correct debug compile error in asc_prt_adv_scsi_req_q().
580 2. Update Adv Library to 5.5.
581 3. Add ifdef handling for /proc changes added in v2.3.28.
582 4. Increase Wide board scatter-gather list maximum length to
583 255 when the driver is compiled into the kernel.
584
585 3.2L (11/18/99):
586 1. Fix bug in adv_get_sglist() that caused an assertion failure
587 at line 7475. The reqp->sgblkp pointer must be initialized
588 to NULL in adv_get_sglist().
589
590 3.2M (11/29/99):
591 1. Really fix bug in adv_get_sglist().
592 2. Incorporate v2.3.29 changes into driver.
593
594 3.2N (4/1/00):
595 1. Add CONFIG_ISA ifdef code.
596 2. Include advansys_interrupts_enabled name change patch.
597 3. For >= v2.3.28 use new SCSI error handling with new function
598 advansys_eh_bus_reset(). Don't include an abort function
599 because of base library limitations.
600 4. For >= v2.3.28 use per board lock instead of io_request_lock.
601 5. For >= v2.3.28 eliminate advansys_command() and
602 advansys_command_done().
603 6. Add some changes for PowerPC (Big Endian) support, but it isn't
604 working yet.
605 7. Fix "nonexistent resource free" problem that occurred on a module
606 unload for boards with an I/O space >= 255. The 'n_io_port' field
607 is only one byte and can not be used to hold an ioport length more
608 than 255.
609
610 3.3A (4/4/00):
611 1. Update to Adv Library 5.8.
612 2. For wide cards add support for CDBs up to 16 bytes.
613 3. Eliminate warnings when CONFIG_PROC_FS is not defined.
614
615 3.3B (5/1/00):
616 1. Support for PowerPC (Big Endian) wide cards. Narrow cards
617 still need work.
618 2. Change bitfields to shift and mask access for endian
619 portability.
620
621 3.3C (10/13/00):
622 1. Update for latest 2.4 kernel.
623 2. Test ABP-480 CardBus support in 2.4 kernel - works!
624 3. Update to Asc Library S123.
625 4. Update to Adv Library 5.12.
626
627 3.3D (11/22/00):
628 1. Update for latest 2.4 kernel.
629 2. Create patches for 2.2 and 2.4 kernels.
630
631 3.3E (1/9/01):
632 1. Now that 2.4 is released remove ifdef code for kernel versions
633 less than 2.2. The driver is now only supported in kernels 2.2,
634 2.4, and greater.
635 2. Add code to release and acquire the io_request_lock in
636 the driver entrypoint functions: advansys_detect and
637 advansys_queuecommand. In kernel 2.4 the SCSI mid-level driver
638 still holds the io_request_lock on entry to SCSI low-level drivers.
639 This was supposed to be removed before 2.4 was released but never
640 happened. When the mid-level SCSI driver is changed all references
641 to the io_request_lock should be removed from the driver.
642 3. Simplify error handling by removing advansys_abort(),
643 AscAbortSRB(), AscResetDevice(). SCSI bus reset requests are
644 now handled by resetting the SCSI bus and fully re-initializing
645 the chip. This simple method of error recovery has proven to work
646 most reliably after attempts at different methods. Also now only
647 support the "new" error handling method and remove the obsolete
648 error handling interface.
649 4. Fix debug build errors.
650
651 3.3F (1/24/01):
652 1. Merge with ConnectCom version from Andy Kellner which
653 updates Adv Library to 5.14.
654 2. Make PowerPC (Big Endian) work for narrow cards and
655 fix problems writing EEPROM for wide cards.
656 3. Remove interrupts_enabled assertion function.
657
658 3.3G (2/16/01):
659 1. Return an error from narrow boards if passed a 16 byte
660 CDB. The wide board can already handle 16 byte CDBs.
661
662 3.3GJ (4/15/02):
663 1. hacks for lk 2.5 series (D. Gilbert)
664
665 3.3GJD (10/14/02):
666 1. change select_queue_depths to slave_configure
667 2. make cmd_per_lun be sane again
668
669 3.3K [2004/06/24]:
670 1. continuing cleanup for lk 2.6 series
671 2. Fix problem in lk 2.6.7-bk2 that broke PCI wide cards
672 3. Fix problem that oopsed ISA cards
673
674 I. Known Problems/Fix List (XXX)
675
676 1. Need to add memory mapping workaround. Test the memory mapping.
677 If it doesn't work revert to I/O port access. Can a test be done
678 safely?
679 2. Handle an interrupt not working. Keep an interrupt counter in
680 the interrupt handler. In the timeout function if the interrupt
681 has not occurred then print a message and run in polled mode.
682 3. Allow bus type scanning order to be changed.
683 4. Need to add support for target mode commands, cf. CAM XPT.
