42 A. Linux Kernel Testing
43
44 This driver has been tested in the following Linux kernels: v1.2.13,
45 v1.3.57, v2.0.33, v2.1.77. These kernel versions are major releases
46 of Linux or the latest Linux kernel versions available when this version
47 of the driver was released. The driver should also work in earlier
48 versions of the Linux kernel. Beginning with v1.3.58 the AdvanSys driver
49 is included with all Linux kernels. Please refer to sections C, D, and
50 E for instructions on adding or upgrading the AdvanSys driver.
51
52 B. Adapters Supported by this Driver
53
54 AdvanSys (Advanced System Products, Inc.) manufactures the following
55 RISC-based, Bus-Mastering, Fast (10 Mhz) and Ultra (20 Mhz) Narrow
56 (8-bit transfer) SCSI Host Adapters for the ISA, EISA, VL, and PCI
57 buses and RISC-based, Bus-Mastering, Ultra (20 Mhz) Wide (16-bit
58 transfer) SCSI Host Adapters for the PCI bus.
59
60 The CDB counts below indicate the number of SCSI CDB (Command
61 Descriptor Block) requests that can be stored in the RISC chip
62 cache and board LRAM. A CDB is a single SCSI command. The driver
63 detect routine will display the number of CDBs available for each
64 adapter detected. The number of CDBs used by the driver can be
65 lowered in the BIOS by changing the 'Host Queue Size' adapter setting.

104 C. Linux v1.2.X - Directions for Adding the AdvanSys Driver
105
106 These directions apply to v1.2.13. For versions that follow v1.2.13.
107 but precede v1.3.57 some of the changes for Linux v1.3.X listed
108 below may need to be modified or included. A patch is available
109 for v1.2.13 from the AdvanSys WWW and FTP sites.
110
111 There are two source files: advansys.h and advansys.c. Copy
112 both of these files to the directory /usr/src/linux/drivers/scsi.
113
114 1. Add the following line to /usr/src/linux/arch/i386/config.in
115 after "comment 'SCSI low-level drivers'":
116
117 bool 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS y
118
119 2. Add the following lines to /usr/src/linux/drivers/scsi/hosts.c
120 after "#include "hosts.h"":
121
122 #ifdef CONFIG_SCSI_ADVANSYS
123 #include "advansys.h"
124 #endif
125
126 and after "static Scsi_Host_Template builtin_scsi_hosts[] =":
127
128 #ifdef CONFIG_SCSI_ADVANSYS
129 ADVANSYS,
130 #endif
131
132 3. Add the following lines to /usr/src/linux/drivers/scsi/Makefile:
133
134 ifdef CONFIG_SCSI_ADVANSYS
135 SCSI_SRCS := $(SCSI_SRCS) advansys.c
136 SCSI_OBJS := $(SCSI_OBJS) advansys.o
137 else
138 SCSI_MODULE_OBJS := $(SCSI_MODULE_OBJS) advansys.o
139 endif
140
141 4. (Optional) If you would like to enable the LILO command line
142 and /etc/lilo.conf 'advansys' option, make the following changes.
143 This option can be used to disable I/O port scanning or to limit
144 I/O port scanning to specific addresses. Refer to the 'Driver
145 LILO Option' section below. Add the following lines to
146 /usr/src/linux/init/main.c in the prototype section:
147
148 extern void advansys_setup(char *str, int *ints);
149
150 and add the following lines to the bootsetups[] array.
151
152 #ifdef CONFIG_SCSI_ADVANSYS
153 { "advansys=", advansys_setup },
154 #endif
155
156 5. If you have the HP 4020i CD-R driver and Linux v1.2.X you should
157 add a fix to the CD-ROM target driver. This fix will allow
158 you to mount CDs with the iso9660 file system. Linux v1.3.X
159 already has this fix. In the file /usr/src/linux/drivers/scsi/sr.c
160 and function get_sectorsize() after the line:
161
162 if(scsi_CDs[i].sector_size == 0) scsi_CDs[i].sector_size = 2048;
163
164 add the following line:
165
166 if(scsi_CDs[i].sector_size == 2340) scsi_CDs[i].sector_size = 2048;
167
168 6. In the directory /usr/src/linux run 'make config' to configure
169 the AdvanSys driver, then run 'make vmlinux' or 'make zlilo' to
170 make the kernel. If the AdvanSys driver is not configured, then
171 a loadable module can be built by running 'make modules' and
172 'make modules_install'. Use 'insmod' and 'rmmod' to install
173 and remove advansys.o.
174
175 D. Linux v1.3.1 - v1.3.57 - Directions for Adding the AdvanSys Driver
176
177 These directions apply to v1.3.57. For versions that precede v1.3.57
178 some of these changes may need to be modified or eliminated. A patch
179 is available for v1.3.57 from the AdvanSys WWW and FTP sites.
180 Beginning with v1.3.58 this driver is included with the Linux
181 distribution eliminating the need for making any changes.
182
183 There are two source files: advansys.h and advansys.c. Copy
184 both of these files to the directory /usr/src/linux/drivers/scsi.
185
186 1. Add the following line to /usr/src/linux/drivers/scsi/Config.in
187 after "comment 'SCSI low-level drivers'":
188
189 dep_tristate 'AdvanSys SCSI support' CONFIG_SCSI_ADVANSYS $CONFIG_SCSI
190
191 2. Add the following lines to /usr/src/linux/drivers/scsi/hosts.c
192 after "#include "hosts.h"":
193
194 #ifdef CONFIG_SCSI_ADVANSYS
195 #include "advansys.h"
196 #endif
197
198 and after "static Scsi_Host_Template builtin_scsi_hosts[] =":
199
200 #ifdef CONFIG_SCSI_ADVANSYS
201 ADVANSYS,
202 #endif
203
204 3. Add the following lines to /usr/src/linux/drivers/scsi/Makefile:
205
206 ifeq ($(CONFIG_SCSI_ADVANSYS),y)
207 L_OBJS += advansys.o
208 else
209 ifeq ($(CONFIG_SCSI_ADVANSYS),m)
210 M_OBJS += advansys.o
211 endif
212 endif
213
214 4. Add the following line to /usr/src/linux/include/linux/proc_fs.h
215 in the enum scsi_directory_inos array:
216
217 PROC_SCSI_ADVANSYS,
218
219 5. (Optional) If you would like to enable the LILO command line
220 and /etc/lilo.conf 'advansys' option, make the following changes.
221 This option can be used to disable I/O port scanning or to limit
222 I/O port scanning to specific addresses. Refer to the 'Driver
223 LILO Option' section below. Add the following lines to
224 /usr/src/linux/init/main.c in the prototype section:
225
226 extern void advansys_setup(char *str, int *ints);
227
228 and add the following lines to the bootsetups[] array.
229
230 #ifdef CONFIG_SCSI_ADVANSYS
231 { "advansys=", advansys_setup },
232 #endif
233
234 6. In the directory /usr/src/linux run 'make config' to configure
235 the AdvanSys driver, then run 'make vmlinux' or 'make zlilo' to
236 make the kernel. If the AdvanSys driver is not configured, then
237 a loadable module can be built by running 'make modules' and
238 'make modules_install'. Use 'insmod' and 'rmmod' to install
239 and remove advansys.o.
240
241 E. Linux v1.3.58 and Newer - Upgrading the AdvanSys Driver
242
243 To upgrade the AdvanSys driver in a Linux v1.3.58 and newer
244 kernel, first check the version of the current driver. The
245 version is defined by the manifest constant ASC_VERSION at
246 the beginning of advansys.c. The new driver should have a
247 ASC_VERSION value greater than the current version. To install
248 the new driver rename advansys.c and advansys.h in the Linux
249 kernel source tree drivers/scsi directory to different names
250 or save them to a different directory in case you want to revert
251 to the old version of the driver. After the old driver is saved
252 copy the new advansys.c and advansys.h to drivers/scsi, rebuild
253 the kernel, and install the new kernel. No other changes are needed.
254
255 F. Source Comments
256
257 1. Use tab stops set to 4 for the source files. For vi use 'se tabstops=4'.
258
259 2. This driver should be maintained in multiple files. But to make
260 it easier to include with Linux and to follow Linux conventions,
261 the whole driver is maintained in the source files advansys.h and
262 advansys.c. In this file logical sections of the driver begin with
263 a comment that contains '---'. The following are the logical sections
264 of the driver below.

288 4. I have stripped comments from and reformatted the source for the
289 Asc Library and Adv Library to reduce the size of this file. This
290 source can be found under the following headings. The Asc Library
291 is used to support Narrow Boards. The Adv Library is used to
292 support Wide Boards.

299 G. Driver Compile Time Options and Debugging
300
301 In this source file the following constants can be defined. They are
302 defined in the source below. Both of these options are enabled by
303 default.
304
305 1. ADVANSYS_ASSERT - Enable driver assertions (Def: Enabled)
306
307 Enabling this option adds assertion logic statements to the
308 driver. If an assertion fails a message will be displayed to
309 the console, but the system will continue to operate. Any
310 assertions encountered should be reported to the person
311 responsible for the driver. Assertion statements may proactively
312 detect problems with the driver and facilitate fixing these
313 problems. Enabling assertions will add a small overhead to the
314 execution of the driver.
315
316 2. ADVANSYS_DEBUG - Enable driver debugging (Def: Disabled)
317
318 Enabling this option adds tracing functions to the driver and
319 the ability to set a driver tracing level at boot time. This
320 option will also export symbols not required outside the driver to
321 the kernel name space. This option is very useful for debugging
322 the driver, but it will add to the size of the driver execution
323 image and add overhead to the execution of the driver.
324
325 The amount of debugging output can be controlled with the global
326 variable 'asc_dbglvl'. The higher the number the more output. By
327 default the debug level is 0.
328
329 If the driver is loaded at boot time and the LILO Driver Option
330 is included in the system, the debug level can be changed by
331 specifying a 5th (ASC_NUM_IOPORT_PROBE + 1) I/O Port. The
332 first three hex digits of the pseudo I/O Port must be set to
333 'deb' and the fourth hex digit specifies the debug level: 0 - F.
334 The following command line will look for an adapter at 0x330
335 and set the debug level to 2.
336
337 linux advansys=0x330,0,0,0,0xdeb2
338
339 If the driver is built as a loadable module this variable can be
340 defined when the driver is loaded. The following insmod command
341 will set the debug level to one.
342
343 insmod advansys.o asc_dbglvl=1
344
345 Debugging Message Levels:
346 0: Errors Only
347 1: High-Level Tracing
348 2-N: Verbose Tracing
349
350 I don't know the approved way for turning on printk()s to the
351 console. Here's a program I use to do this. Debug output is
352 logged in /var/adm/messages.
353
354 main()
355 {
356 syscall(103, 7, 0, 0);
357 }
358
359 I found that increasing LOG_BUF_LEN to 40960 in kernel/printk.c
360 prevents most level 1 debug messages from being lost.
361
362 3. ADVANSYS_STATS - Enable statistics (Def: Enabled >= v1.3.0)
363
364 Enabling this option adds statistics collection and display
365 through /proc to the driver. The information is useful for
366 monitoring driver and device performance. It will add to the
367 size of the driver execution image and add minor overhead to
368 the execution of the driver.
369
370 Statistics are maintained on a per adapter basis. Driver entry
371 point call counts and transfer size counts are maintained.
372 Statistics are only available for kernels greater than or equal
373 to v1.3.0 with the CONFIG_PROC_FS (/proc) file system configured.
374
375 AdvanSys SCSI adapter files have the following path name format:
376
377 /proc/scsi/advansys/[0-(ASC_NUM_BOARD_SUPPORTED-1)]
378
379 This information can be displayed with cat. For example:
380
381 cat /proc/scsi/advansys/0
382
383 When ADVANSYS_STATS is not defined the AdvanSys /proc files only
384 contain adapter and device configuration information.
385
386 H. Driver LILO Option
387
388 If init/main.c is modified as described in the 'Directions for Adding
389 the AdvanSys Driver to Linux' section (B.4.) above, the driver will
390 recognize the 'advansys' LILO command line and /etc/lilo.conf option.
391 This option can be used to either disable I/O port scanning or to limit
392 scanning to 1 - 4 I/O ports. Regardless of the option setting EISA and
393 PCI boards will still be searched for and detected. This option only
394 affects searching for ISA and VL boards.
395
396 Examples:
397 1. Eliminate I/O port scanning:
398 boot: linux advansys=
399 or
400 boot: linux advansys=0x0
401 2. Limit I/O port scanning to one I/O port:
402 boot: linux advansys=0x110
403 3. Limit I/O port scanning to four I/O ports:
404 boot: linux advansys=0x110,0x210,0x230,0x330
405
406 For a loadable module the same effect can be achieved by setting
407 the 'asc_iopflag' variable and 'asc_ioport' array when loading
408 the driver, e.g.
409
410 insmod advansys.o asc_iopflag=1 asc_ioport=0x110,0x330
411
412 If ADVANSYS_DEBUG is defined a 5th (ASC_NUM_IOPORT_PROBE + 1)
413 I/O Port may be added to specify the driver debug level. Refer to
414 the 'Driver Compile Time Options and Debugging' section above for
415 more information.
416
417 I. Release History
418
419 BETA-1.0 (12/23/95):

422 BETA-1.1 (12/28/95):
423 1. Prevent advansys_detect() from being called twice.
424 2. Add LILO 0xdeb[0-f] option to set 'asc_dbglvl'.
425
426 1.2 (1/12/96):
427 1. Prevent re-entrancy in the interrupt handler which
428 resulted in the driver hanging Linux.

430 recognized on some PCI motherboards.
431 3. Add support for the ABP-5140 PnP ISA card.
432 4. Fix check condition return status.
433 5. Add conditionally compiled code for Linux v1.3.X.
434
435 1.3 (2/23/96):
436 1. Fix problem in advansys_biosparam() that resulted in the
437 wrong drive geometry being returned for drives > 1GB with
438 extended translation enabled.
439 2. Add additional tracing during device initialization.
440 3. Change code that only applies to ISA PnP adapter.
441 4. Eliminate 'make dep' warning.
442 5. Try to fix problem with handling resets by increasing their
443 timeout value.
444
445 1.4 (5/8/96):
446 1. Change definitions to eliminate conflicts with other subsystems.
447 2. Add versioning code for the shared interrupt changes.
448 3. Eliminate problem in asc_rmqueue() with iterating after removing
449 a request.
450 4. Remove reset request loop problem from the "Known Problems or
451 Issues" section. This problem was isolated and fixed in the
452 mid-level SCSI driver.
453
454 1.5 (8/8/96):
455 1. Add support for ABP-940U (PCI Ultra) adapter.
456 2. Add support for IRQ sharing by setting the SA_SHIRQ flag for
457 request_irq and supplying a dev_id pointer to both request_irq()
458 and free_irq().
459 3. In AscSearchIOPortAddr11() restore a call to check_region() which
460 should be used before I/O port probing.
461 4. Fix bug in asc_prt_hex() which resulted in the displaying
462 the wrong data.

465 7. Change statistics gathering to be per adapter instead of global
466 to the driver.
467 8. Add more information and statistics to the adapter /proc file:
468 /proc/scsi/advansys[0...].
469 9. Remove 'cmd_per_lun' from the "Known Problems or Issues" list.
470 This problem has been addressed with the SCSI mid-level changes
471 made in v1.3.89. The advansys_select_queue_depths() function
472 was added for the v1.3.89 changes.
473

479 of scatter gather elements for any particular board. Clustering
480 increases CPU utilization, but results in a relatively larger
481 increase in I/O throughput.
482 2. Improve the performance of the request queuing functions by
483 adding a last pointer to the queue structure.
484 3. Correct problems with reset and abort request handling that

493 in which a kernel virtual address may not be equivalent to its
494 bus or DMA memory address.
495 2. Change abort and reset request handling to make it yet even
496 more robust.
497 3. Try to mitigate request starvation by sending ordered requests
498 to heavily loaded, tag queuing enabled devices.
499 4. Maintain statistics on request response time.
500 5. Add request response time statistics and other information to
501 the adapter /proc file: /proc/scsi/advansys[0...].
502
503 1.9 (10/21/96):
504 1. Add conditionally compiled code (ASC_QUEUE_FLOW_CONTROL) to
505 make use of mid-level SCSI driver device queue depth flow
506 control mechanism. This will eliminate aborts caused by a
507 device being unable to keep up with requests and eliminate
508 repeat busy or QUEUE FULL status returned by a device.
509 2. Incorporate miscellaneous Asc Library bug fixes.
510 3. To allow the driver to work in kernels with broken module
511 support set 'cmd_per_lun' if the driver is compiled as a
512 module. This change affects kernels v1.3.89 to present.
513 4. Remove PCI BIOS address from the driver banner. The PCI BIOS
514 is relocated by the motherboard BIOS and its new address can
515 not be determined by the driver.
516 5. Add mid-level SCSI queue depth information to the adapter
517 /proc file: /proc/scsi/advansys[0...].
518
519 2.0 (11/14/96):
520 1. Change allocation of global structures used for device
521 initialization to guarantee they are in DMA-able memory.
522 Previously when the driver was loaded as a module these
523 structures might not have been in DMA-able memory, causing
524 device initialization to fail.
525
526 2.1 (12/30/96):
527 1. In advansys_reset(), if the request is a synchronous reset
528 request, even if the request serial number has changed, then
529 complete the request.
530 2. Add Asc Library bug fixes including new microcode.
531 3. Clear inquiry buffer before using it.
532 4. Correct ifdef typo.
533
534 2.2 (1/15/97):
535 1. Add Asc Library bug fixes including new microcode.
536 2. Add synchronous data transfer rate information to the
537 adapter /proc file: /proc/scsi/advansys[0...].
538 3. Change ADVANSYS_DEBUG to be disabled by default. This
539 will reduce the size of the driver image, eliminate execution
540 overhead, and remove unneeded symbols from the kernel symbol
541 space that were previously added by the driver.
542 4. Add new compile-time option ADVANSYS_ASSERT for assertion
543 code that used to be defined within ADVANSYS_DEBUG. This
544 option is enabled by default.
545
546 2.8 (5/26/97):
547 1. Change version number to 2.8 to synchronize the Linux driver
548 version numbering with other AdvanSys drivers.
549 2. Reformat source files without tabs to present the same view
550 of the file to everyone regardless of the editor tab setting
551 being used.
552 3. Add Asc Library bug fixes.
553
554 3.1A (1/8/98):
555 1. Change version number to 3.1 to indicate that support for
556 Ultra-Wide adapters (ABP-940UW) is included in this release.
557 2. Add Asc Library (Narrow Board) bug fixes.
558 3. Report an underrun condition with the host status byte set
559 to DID_UNDERRUN. Currently DID_UNDERRUN is defined to 0 which
560 causes the underrun condition to be ignored. When Linux defines
561 its own DID_UNDERRUN the constant defined in this file can be
562 removed.
563 4. Add patch to AscWaitTixISRDone().
564 5. Add support for up to 16 different AdvanSys host adapter SCSI
565 channels in one system. This allows four cards with four channels
566 to be used in one system.
567
568 3.1B (1/9/98):
569 1. Handle that PCI register base addresses are not always page
570 aligned even though ioremap() requires that the address argument
571 be page aligned.
572
573 3.1C (1/10/98):
574 1. Update latest BIOS version checked for from the /proc file.
575 2. Don't set microcode SDTR variable at initialization. Instead
576 wait until device capabilities have been detected from an Inquiry
577 command.
578
579 3.1D (1/21/98):
580 1. Improve performance when the driver is compiled as module by
581 allowing up to 64 scatter-gather elements instead of 8.
582
583 3.1E (5/1/98):
584 1. Set time delay in AscWaitTixISRDone() to 1000 ms.
585 2. Include SMP locking changes.
586 3. For v2.1.93 and newer kernels use CONFIG_PCI and new PCI BIOS
587 access functions.
588 4. Update board serial number printing.
589 5. Try allocating an IRQ both with and without the SA_INTERRUPT
590 flag set to allow IRQ sharing with drivers that do not set
591 the SA_INTERRUPT flag. Also display a more descriptive error
592 message if request_irq() fails.
593 5. Update to latest Asc and Adv Libraries.
594
595 J. Known Problems or Issues
596
597 1. Remove conditional constants (ASC_QUEUE_FLOW_CONTROL) around
598 the queue depth flow control code when mid-level SCSI changes
599 are included in Linux.

601 K. Credits
602
603 Nathan Hartwell <mage@cdc3.cdc.net> provided the directions and
604 basis for the Linux v1.3.X changes which were included in the
605 1.2 release.
606
607 Thomas E Zerucha <zerucha@shell.portal.com> pointed out a bug
608 in advansys_biosparam() which was fixed in the 1.3 release.
609
610 Erik Ratcliffe <erik@caldera.com> has done testing of the
611 AdvanSys driver in the Caldera releases.
612
613 Rik van Riel <H.H.vanRiel@fys.ruu.nl> provided a patch to
614 AscWaitTixISRDone() which he found necessary to make the
615 driver work with a SCSI-1 disk.
616
617 Mark Moran <mmoran@mmoran.com> has helped test Ultra-Wide
618 support in the 3.1A driver.
